How long did it take to get to the moon in 1969?
The first crewed mission to reach the Moon – The Apollo 11 mission in 1969, crewed by three astronauts took four days, six hours and 45 minutes. Apollo 10 holds the record for the highest velocity reached by a crewed spacecraft at 24,791 miles per hour.

- The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph).
- The trip to Mars will take about seven months and about 300 million miles (480 million kilometers).
- During that journey, engineers have several opportunities to adjust the spacecraft’s flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
The first tweak to the spacecraft’s flight path happens about 15 days after launch.
How quickly can we get to the moon?
- Science & Astronomy
It takes about 3 days to get to the moon using current rocket technology. (Image credit: peepo via Getty Images) If you wanted to go to the moon, how long would it take? Well, the answer depends on a number of factors ranging from the positions of Earth and the moon, to whether you want to land on the surface or just zip past, and especially to the technology used to propel you there.
The average travel time to the moon (providing the moon is your intended destination), using current rocket propulsion is approximately three days. The fastest flight to the moon without stopping was achieved by NASA’s New Horizons probe when it passed the moon in just 8 hours 35 minutes while en route to Pluto,
Currently, the fastest crewed flight to the moon was Apollo 8. The spacecraft entered lunar orbit just 69 hours and 8 minutes after launch according to NASA, Here we take a look at how long a trip to the moon would take using available technology and explore the travel times of previous missions to our lunar companion.
How long did it take Apollo 11 to reach the moon?
How Long Does It Take to Get to the Moon? American geologist and astronaut Harrison Hagan Schmitt takes rock samples from the surface of the moon during America’s last lunar landing mission of the 20th century, Apollo 17, December 1972. Space Frontiers/Getty Images Shining brightly overhead most nights, we often take the for granted.
Our nearest celestial neighbor and satellite has a lot more impact in our lives than we realize though, helping affect the, animal sleep cycles (including !), and, It has also long inspired us to look up and reach beyond the atmosphere of our own planet; that’s part of why President John F. Kennedy set his sights and in the 1960s.
So far, American astronauts have made nine journeys to the moon – six of which landed on the lunar surface. Based on this data, we now have a good idea about how long it takes to get to the moon. NASA, other governments, and other private companies are now planning crewed missions back to the moon and will give us even more data about how long it takes to reach the moon.
Like other orbiting bodies in space, the moon’s orbit is not exactly circular; it is, This means that the moon is closer to Earth at some times and further than others – that’s why we keep hearing about “” when the moon is closer. (The point of orbit when the moon is closest to Earth is called ; the point of orbit when it is furthest away from Earth is called apogee).
Taking advantage of orbital mechanics, astrophysicists can plan lunar missions to coincide when those times that the moon is closer to Earth. Historically, most lunar missions have taken about three days to reach the moon, assuming the moon is at an ideal distance of,
This means astronauts travel roughly 3,333 mph (5,364 kph) on their journey to the moon. Some uncrewed missions have taken longer in an attempt to save on fuel weight (such as China’s Chang’e missions which have taken ). The fastest-ever mission to the moon was the very first one: 1959’s unmanned Luna 1 took just at a speed of roughly 6,500 mph (10,500 kph).
In 2006, New Horizons zoomed past the moon on its way to Pluto just after launch and at a speed of 36,373 mph (58,536 kph). Now That’s Interesting Want proof that orbital mechanics are real? The Apollo 11 mission demonstrates that well. It took the Apollo 11 astronauts three days, three hours and 49 minutes to reach the moon, but they returned in,
When did Russia land on the moon?
Successful impact at 21:02 on 14 September 1959. First spacecraft to reach lunar surface. The impact made the Soviet Union the 1st country to reach the surface of the Moon. Returned first images of the far side of the Moon.
Why did it take 3 days to get to the Moon?
It takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon. The specific distance depends on the specific path chosen.
Do we age faster in space?
Previous research has shown that spending time in space causes bone density loss, immune dysfunction, cardiovascular issues such as stiffening of arteries, and loss of skeletal muscle mass and strength in both humans and rodent models. These changes resemble aging in people age on Earth, but happen more quickly.
How long would it take to get to Pluto?
How Long Does It Take to Get to Pluto? It’s a long way out to the dwarf planet Pluto. So, just how fast could we get there? Pluto, the Dwarf planet, is an incomprehensibly long distance away. Seriously, it’s currently more than 5 billion kilometers away from Earth.
- It challenges the imagination that anyone could ever travel that kind of distance, and yet, NASA’s New Horizons has been making the journey, and it’s going to arrive there July, 2015.
- You may have just heard about this news.
- And I promise you, when New Horizons makes its close encounter, it’s going to be everywhere.
So let me give you the advanced knowledge on just how amazing this journey is, and what it would take to cross this enormous gulf in the Solar System. Pluto travels on a highly elliptical orbit around the Sun. At its closest point, known as “perihelion”, Pluto is only 4.4 billion kilometers out.
That’s nearly 30 AU, or 30 times the distance from the Earth to the Sun. Pluto last reached this point on September 5th, 1989. At its most distant point, known as “aphelion”, Pluto reaches a distance of 7.3 billion kilometers, or 49 AU. This will happen on August 23, 2113. I know, these numbers seem incomprehensible and lose their meaning.
So let me give you some context. Light itself takes 4.6 hours to travel from the Earth to Pluto. If you wanted to send a signal to Pluto, it would take 4.6 hours for your transmission to reach Pluto, and then an additional 4.6 hours for their message to return to us.
Let’s talk spacecraft. When New Horizons blasted off from Earth, it was going 58,000 km/h. Just for comparison, astronauts in orbit are merely jaunting along at 28,000 km/h. That’s its speed going away from the Earth. When you add up the speed of the Earth, New Horizons was moving away from the Sun at a blistering 160,000 km/h.
Unfortunately, the pull of gravity from the Sun slowed New Horizons down. By the time it reached Jupiter, it was only going 68,000 km/h. It was able to steal a little velocity from Jupiter and crank its speed back up to 83,000 km/h. When it finally reaches Pluto, it’ll be going about 50,000 km/h.
- So how long did this journey take? Artist’s conception of the New Horizons spacecraft at Pluto.
- Credit: Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute (JHUAPL/SwRI) New Horizons launched on January 19, 2006, and it’ll reach Pluto on July 14, 2015.
- Do a little math and you’ll find that it has taken 9 years, 5 months and 25 days.
The Voyager spacecraft did the distance between Earth and Pluto in about 12.5 years, although, neither spacecraft actually flew past Pluto. And the Pioneer spacecraft completed the journey in about 11 years. Could you get to Pluto faster? Absolutely. With a more powerful rocket, and a lighter spacecraft payload, you could definitely shave down the flight time.
But there are a couple of problems. Rockets are expensive, coincidentally bigger rockets are super expensive. The other problem is that getting to Pluto faster means that it’s harder to do any kind of science once you reach the dwarf planet. New Horizons made the fastest journey to Pluto, but it’s also going to fly past the planet at 50,000 km/h.
That’s less time to take high resolution images. And if you wanted to actually go into orbit around Pluto, you’d need more rockets to lose all that velocity. So how long does it take to get to Pluto? Roughly 9-12 years. You could probably get there faster, but then you’d get less science done, and it probably wouldn’t be worth the rush.

: How Long Does It Take to Get to Pluto?
Is the flag on the Moon still there?
Guests at public star parties often ask us, “Can we see the flags on the Moon erected by the Apollo astronauts over 50 years ago?” This question contains two questions within it. First, “Can we directly see the flags on the Moon with an Earthbound telescope?” and second, “Can we see the flags on the Moon with a space telescope?” Let’s tackle them one at a time.
- Can we directly see the flags on the Moon with an Earthbound telescope? The answer is no.
- The largest of the American flags on the Moon is the one left by Apollo 17.
- It spans six feet when unfurled.
- A target that small at the quarter million-mile lunar distance is beyond the reach of any Earthbound telescope, even the most sophisticated professional observatories equipped with state-of-the-art optics.
To show the limitations of Earthly telescopes in observing ultra-small detail on the Moon, well-known astronomer Yuri Beletsky at the European Southern Observatory in Chile conducted an experiment using an eight-meter adaptive optics telescope. He tried to visually spot the 150-foot-long shadow of one of the Apollo landing stages still resting on the Moon.
- His attempt failed, showing that viewing the flags, targets at least ten times smaller, is impossible with current technology.
- Can we see the flags on the Moon with a space telescope? What about space-based telescopes that don’t have to contend with such vast distances and the Earth’s atmosphere? Here we have better news.
NASA’s Lunar Reconnaissance Orbiter (LRO) satellite, tasked with mapping the Moon’s surface from lunar orbit for a decade, does achieve sufficient resolution to spot the shadows of three Apollo flags. In fact, LRO’s cameras can see objects as small as 20 inches on the surface of the Moon, sufficient to positively identify the extended shadows streaming from the Apollo 12, 16, and 17 flags.
- What happened to the six American flags on the Moon? Why have we only seen three of the six flags American astronauts planted on the Moon? Let’s look at the status of the flags from the six Apollo expeditions that landed on the Moon between 1969 and 1972.
- Buzz Aldrin saw the Apollo 11 flag blow over when the Lunar Module Eagle took off from the Moon on July 21st, 1969.
Aldrin and fellow Moonwalker Neil Armstrong planted the flag just 27 feet from the centerline of the lunar lander. The flagpole did not withstand the rocket exhaust of liftoff. Subsequent missions placed the flag farther from the lander to ensure they remained upright.
The LRO images clearly show that the Apollo 12, 16, and 17 flags are still intact on their flagpoles after half a century of exposure to harsh lunar environments. While it is true that there is no wind and weather on the Moon to damage the flags, unfiltered solar radiation and temperature extremes have not been kind to the flags.
The LRO has not yet captured the shadows of the Apollo 14 and 15 flags, so their status remains unknown. The extremes of the lunar environment may explain why the shadows of the Apollo 14 and 15 flags have not yet been identified. Since the astronauts first unfurled the flags, they have endured 600 cycles of broiling +100C two Earth-week-long lunar days and equally long frigid -150C lunar nights.
Unfiltered solar ultraviolet radiation on the airless lunar surface has likely bleached all the flags white. The radiation has rendered the nylon thread in the flags very brittle, and the Apollo 14 and 15 flags may have disintegrated. However, LRO photography has positively confirmed the Apollo 12, 16, and 17 flags are still erect on the Moon.
More about the American flags on the Moon There is nothing special or “high-tech” about the flags the Apollo astronauts left behind on the Moon. Except for the larger Apollo 17 flag, they are all ordinary three-by-five-foot nylon cloth flags ordered from a 1969 government supply catalog for $5.50 apiece.
Since there is no wind on the Moon to make the flag wave, each of the Apollo flags was modified with a stitched hem at the top to accept a one-inch diameter horizontal tube to display the unfurled flag. Using gold anodized aluminum tubing, workers at the Johnson Space Center in Houston created a two-piece flagpole with a hinged latch at the top to support the horizontal display tube.
Each of the lunar flag poles costs about $70. The lunar flags and their poles traveled to the Moon in an insulated tube attached to the landing stage of the lunar module. Engineers designed the tubes to withstand rocket exhaust temperatures that reached 2,000C in the final seconds before the lunar touchdown.
- The Apollo 17 flag deserves special note because it is the only American flag to fly to the Moon twice.
- This larger, six-foot-wide flag initially flew to the Moon and back aboard Apollo 11, then hung on the wall in Houston’s Mission Control Center during Apollo 12 through 16.
- Finally, Apollo 17 returned the flag to the Moon, where astronauts Gene Cernan and Harrison Schmidt erected it in the Taurus-Littrow Valley.
To date, the six American flags the Apollo astronauts raised are the only flags planted on another world by humans. Many “old-timers” in astronomy remember the pride we felt during the heady days of the Apollo landings. We look up at the Moon with fond memories of how it lured us into this fascinating hobby. The American flags erected on the Moon by the Apollo astronauts were off-the-shelf nylon flags supported by a gold-anodized aluminum flagpole pushed into the lunar soil by the astronauts.

How many countries have walked on the Moon?
Which countries have landed on the moon? The United States is the only country that has successfully landed humans on the moon, which it did six times from 1967 to 1972. However, the US and three other countries—the USSR/Russia, China, and India—have landed unmanned probes on the moon.
How many times have we gone to moon?
Why haven’t we been back to the Moon? – The Apollo 11 Moon landing in July 1969 was a huge feat of human endeavour, engineering and science. It was a moment that the world had been waiting for. Apollo 11 was followed by six further trips to the Moon, five of which landed successfully.12 men walked on the lunar surface in total.
Has any human been to Mars?
Not yet, but we’ve sent rovers, landers, and orbiters to. gather the information we’ll need to keep future. astronauts safe, and with NASA Artemis, we’re. working on new tech that could one day get humans to.
How much does it cost to go to the moon?
NASA this week revealed details about its forthcoming Artemis missions to the Moon. NASA NASA yesterday revealed that its forthcoming Artemis missions to the Moon—including crewed landings on the lunar surface— will cost around $28 billion, Think that’s a lot of money for a NASA moon mission? Shouldn’t that money be spent on something else? Why is it so expensive? “Pushing the boundaries of space exploration, science and technology once again, America is on the verge of exploring more of the Moon than ever before,” said Jim Bridenstine, NASA administrator, in a new NASA document on the Artemis missions published this week.

Why is Russia going to moon?
Science Updated on Aug 10, 2023 7:48 PM EDT — Published on Aug 10, 2023 6:50 PM EDT TALLINN, Estonia (AP) — A rocket carrying a lunar landing craft blasted off Friday on Russia’s first moon mission in nearly 50 years, racing to land on Earth’s satellite ahead of an Indian spacecraft.
- The launch from Russia’s Vostochny spaceport in the Far East of the Luna-25 craft to the moon is Russia’s first since 1976 when it was part of the Soviet Union.
- The Russian lunar lander is expected to reach the moon on Aug.23, about the same day as an Indian craft which was launched on July 14,
- The Russian spacecraft will take about 5.5 days to travel to the moon’s vicinity, then spend three to seven days orbiting at about 100 kilometers (62 miles) before heading for the surface.
Only three governments have managed successful moon landings: the Soviet Union, the United States and China, India and Russia are aiming to be the first to land at the moon’s south pole. Roscosmos, Russia’s space agency, said it wants to show Russia “is a state capable of delivering a payload to the moon,” and “ensure Russia’s guaranteed access to the moon’s surface.” “Study of the moon is not the goal,” said Vitaly Egorov, a popular Russian space analyst.
“The goal is political competition between two superpowers — China and the USA — and a number of other countries which also want to claim the title of space superpower.” Sanctions imposed on Russia after it invaded Ukraine make it harder for it to access Western technology, impacting its space program.
The Luna-25 was initially meant to carry a small moon rover but that idea was abandoned to reduce the weight of the craft for improved reliability, analysts say. READ MORE: Tokyo private company loses contact with moon lander moments before touchdown “Foreign electronics are lighter, domestic electronics are heavier,” Egorov said.
While scientists might have the task of studying lunar water, for Roscosmos the main task is simply to land on the moon — to recover lost Soviet expertise and learn how to perform this task in a new era.” The Luna-25 launched flawlessly from the Vostochny Cosmodrome in Russia’s Far East, according to video feed from Roscosmos.
The spaceport is a pet project of Russian President Vladimir Putin and is key to his efforts to make Russia a space superpower and move Russian launches from the Baikonur Cosmodrome in Kazakhstan. A previous Indian attempt to land at the moon’s south pole in 2019 ended when the lander crashed into the moon’s surface.
The lunar south pole is of particular interest to scientists, who believe the permanently shadowed polar craters may contain water. The frozen water in the rocks could be transformed by future explorers into air and rocket fuel. READ MORE: Moon holds more water in more places than ever thought “The moon is largely untouched and the whole history of the moon is written on its face,” said Ed Bloomer, an astronomer at Britain’s Royal Observatory, Greenwich.
“It is pristine and like nothing you get on Earth. It is its own laboratory.” The Luna-25 is to take samples of moon rock and dust. The samples are crucial to understanding the moon’s environment ahead of building any base there, “otherwise we could be building things and having to shut them down six months later because everything has effectively been sand-blasted,” Bloomer said.

How many Russians have walked on the moon?
Updated on: September 1, 2023 / 8:05 AM / CBS News Russia’s robotic moon craft crashes Russia’s robotic moon craft crashes 00:21 Russia’s Luna-25 probe likely left a 33-foot-wide crater on the surface of the moon last month when it lost control and crashed down, NASA said Thursday, revealing images that show the suspected impact site. Russia’s first moon mission in 47 years ended in failure on August 19 when the Luna-25 probe smashed into the moon after a thruster firing went awry, cutting off communications and putting the spacecraft on the wrong orbital path, according to Roscosmos, the Russian space agency. NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft captured images last week of what the U.S. space agency described as a ” new crater ” after Roscosmos published an estimate of where the probe had struck. During the descent to the surface on August 19, the Russian spacecraft Luna-25 experienced an anomaly that caused it to smash into the moon’s surface. The faiint arrow in this NASA image shows where the agency believes the probe made impact. NASA’s Goddard Space Flight Center/Arizona State University “Since this new crater is close to the Luna-25 estimated impact point,” NASA wrote in a statement, “the LRO team concludes it is likely to be from that mission, rather than a natural impactor.” Moscow has set up a commission to investigate exactly why Luna-25 crashed.
The failure was a major disappointment for the Russian space program, which was attempting to up its game amid renewed interest in the moon’s southern polar region, where ice deposits may exist in permanently shadowed craters. Ice could offer future space missions a way to produce breathable air, water and even hydrogen rocket fuel.
The Russians have had little success with independent space exploration since the Luna-24 robot landed on the moon in 1976. It scooped up about six ounces of lunar soil and returned it to Earth in Russia’s third successful robotic lunar sample return mission.
- Twelve NASA astronauts walked on the moon a half century ago in the agency’s Apollo program, but no Russian cosmonauts ever made the trip.
- Russia’s only previous post-Soviet deep space robotic missions, both targeting Mars, ended in failure.
- Former NASA astronaut breaks down India’s moon landing 04:34 Luna-25 was an attempt to pick up the torch and put Russia back into a new space race of sorts, as the U.S., China, India, Japan and the private sector all plan multiple moon missions that could lay the foundations for lunar bases and eventual flights to Mars.
India’s Chandrayaan-3 Vikram lunar lander made a historic touch-down near the moon’s south pole just several days after the Russian probe crashed. It delivered a lunar rover that has already sent back data from soil samples, William Harwood contributed to this report.

Has Russia sent a person to the moon?
The Soviet crewed lunar programs were a series of programs pursued by the Soviet Union to land humans on the Moon, in competition with the United States Apollo program, The Soviet government publicly denied participating in such a competition, but secretly pursued two programs in the 1960s: crewed lunar flyby missions using Soyuz 7K-L1 (Zond) spacecraft launched with the Proton-K rocket, and a crewed lunar landing using Soyuz 7K-LOK and LK spacecraft launched with the N1 rocket,
- Following the dual American successes of the first crewed lunar orbit on 24–25 December 1968 ( Apollo 8 ) and the first Moon landing on July 20, 1969 ( Apollo 11 ), and a series of catastrophic N1 failures, both Soviet programs were eventually brought to an end.
- The Proton-based Zond program was canceled in 1970, and the N1-L3 program was de facto terminated in 1974 and officially canceled in 1976.
Soviet cosmonauts never orbited nor landed on the Moon. Details of both Soviet programs were kept secret until 1990 when the government allowed them to be published under the policy of glasnost,
Why can’t we go back to the Moon?
The challenges beyond politics – Foto: Many space enthusiasts have long hoped to build a base on the moon, but the lunar surface’s harsh environment wouldn’t be an ideal place for humans to thrive.sourceNASA The political tug-of-war over NASA’s mission and budget isn’t the only reason people haven’t returned to the moon.
The moon is also a 4.5-billion-year-old death trap for humans and must not be trifled with or underestimated. Its surface is littered with craters and boulders that threaten safe landings. Leading up to the first moon landing in 1969, the US government spent what would be billions in today’s dollars to develop, launch, and deliver satellites to the moon to map its surface and help mission planners scout for possible Apollo landing sites.
But a bigger worry is what eons of meteorite impacts have created: regolith, also called moon dust. Madhu Thangavelu, an aeronautical engineer at the University of Southern California, wrote in 2014 that the moon is covered in “a fine, talc-like top layer of lunar dust, several inches deep in some regions, which is electrostatically charged through interaction with the solar wind and is very abrasive and clingy, fouling up spacesuits, vehicles and systems very quickly.” Peggy Whitson, an astronaut who lived in space for a total of 665 days, previously told Business Insider that the Apollo missions “had a lot of problems with dust.” “If we’re going to spend long durations and build permanent habitats, we have to figure out how to handle that,” Whitson said.
- There’s also a problem with sunlight.
- For about 14 days at a time, the lunar surface is a boiling hellscape that is exposed directly to the sun’s harsh rays; the moon has no protective atmosphere.
- The next 14 days are in total darkness, making the moon’s surface one of the colder places in the universe.
A small nuclear reactor being developed by NASA called Kilopower could supply astronauts with electricity during weeks-long lunar nights – and would be useful on other worlds, including Mars. “There is not a more environmentally unforgiving or harsher place to live than the moon,” Thangavelu wrote.
Why haven’t we tried to go to the Moon again?
So, why haven’t they sent humans back to the moon yet? – The two primary causes are money and priorities. The race to put people on the moon was sparked in 1962 by US President John F. Kennedy’s ‘We Choose to Go to the Moon’ address, in which he pledged that by the end of the decade, an American would walk on the moon’.
Why hasn’t anyone went back to the Moon?
Why Didn’t We Go Back to the Moon? | SpaceNext50 The U.S. National Aeronautics and Space Administration (NASA) landed 12 people on the Moon between 1969 and 1972 as a part of the Apollo project. Despite several subsequent policy initiatives by American presidents, however, no humans have landed on the Moon in the decades since.
The Apollo program was a costly endeavor for the United States. While the cost of the program varies between historical sources, most agree that it cost at least $20 billion in 1973 dollars (the equivalent of about $116 billion in 2019). At its peak in the mid-1960s, NASA consumed about 4 percent of annual federal spending, compared with roughly 0.5 percent in recent years.
Cost of Apollo program in 1973 Equivalent cost in 2019 dollars NASA initially planned to send human missions to the Moon through Apollo 20 and then adapt its Moon mission technology for other exploration through the Apollo Applications Program (AAP).
- Congressional cutbacks in NASA allocations, however, accelerated the end of the Moon program to Apollo 17, in 1972.
- Most AAP programs were shelved, with the exception of the space station Skylab.
- There are many reasons why Congress reduced funding to NASA.
- The initial impetus to go to the Moon came from the space race, a competition between the Soviet Union and the United States to show technological and military superiority to other nations.
Later in the 1960s, however, the mood of competition cooled to détente, removing the strategic urgency of investing in NASA. Other public priorities were also coming to the fore, high among them the expensive Vietnam War that required a large share of federal funds.
- Public interest in space also faded after the first human Moon landing, Apollo 11, on July 20, 1969.
- Space historians Roger D.
- Launius and Howard E.
- McCurdy further argue, in their 1997 book Spaceflight and the Myth of Presidential Leadership, that Apollo arose because of a unique circumstance.
- Specifically, U.S.
Pres. John F. Kennedy pursued the space program and Moon landings as one of the chief policies of the United States, due to concern about Soviet military capabilities. After détente, NASA and its programs moved to ancillary policy and have remained there ever since.
- In line with congressional desires, NASA’s priorities changed in the coming decades and its more limited human spaceflight money went to projects other than Moon exploration.
- The next major initiative after Apollo was the partially reusable space shuttle, whose five space vehicles flew 135 missions between 1981 and 2011.
NASA also worked on various space station concepts that eventually culminated in it contributing to the International Space Station (ISS), whose first pieces were launched in 1998. The ISS was billed partly as a science laboratory and partly as an international policy platform—especially with Russia, which was then a new nation just establishing itself after the collapse of the Soviet Union.
Three presidents have proposed new Moon initiatives over the decades, but most ideas were abandoned due to funding and waning congressional will. These were George H.W. Bush’s Space Exploration Initiative to land humans by the turn of the century, and George W. Bush’s Vision for Space Exploration advocating for Moon missions by 2020.
Both initiatives were terminated shortly after each president finished his term. The current administration of Donald Trump has two major Moon initiatives planned: the Gateway lunar space station and Project Artemis, aiming for human landings by the year 2024.
- In June 2019 NASA administrator Jim Bridenstine told reporters that the new Moon landings under Project Artemis could cost NASA between $20 billion and $30 billion in current-day dollars.
- This would be much cheaper than the cost of Apollo, pegged in excess of $115 billion.
- Project Artemis could cost between $20 billion and $30 billion.
Besides the United States and the Soviet Union, no nation in the 1960s had space programs sufficiently advanced to consider human Moon landings. In recent years, however, China, India, Japan, Russia, and the countries within the European Space Agency have all publicly speculated on future Moon landings.
NASA is soliciting its ISS partners for Artemis and Gateway collaborations. As of this writing, Canada is the only partner to commit; it has signed on to provide robotics to the Gateway. Any country or agency that does choose to land people on the Moon will need to accept a certain amount of risk and budgetary commitment.
Human Moon landings require more resources than robotic landings, since humans require water, oxygen, food, and other amenities to remain alive. That said, several nations—including private companies from those nations—are working on robotic Moon initiatives that could support future human missions.
How long did it take to get to the Moon with Neil Armstrong?
How long did it take to reach the moon? – The trio of career astronauts launched on 16 July 1969 from Kennedy Space Center in Cape Canaveral, Florida, It took them four days to travel the 55,200 miles to the surface of the moon. The shuttle landed on the moon’s surface close to midnight on 20 July.
- Early in the wee hours of the morning on 21 July, more than a billion people from around the world watched as Niel Armstrong became the first person to step foot on the moon.
- After taking his first steps, he recited his famous words, ” That’s one small step for a man, one giant leap for mankind.
- Aldrin joined him around twenty minutes later, describing the moon’s surface as ” magnificent desolation,” The two spent a few hours snapping photographs and collecting lunar materials,
As they finish up their moonwalk, they plant an American flag as a memorial to the astronauts killed during the Apollo 1 mission. The plaque left behind with the flag reads, ” Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind,” Armstrong and Aldrin return to the shuttle and are guided back to earth, making landfall on 24 July.
Did it cost to go to the Moon in 1969?
Apollo 11, the first mission to successfully land man on the moon, cost approximately 355 million dollars, and the final mission, Apollo 17, cost approximately 450 million dollars.
Has anyone gone to the Moon after 1969?
Fifty years ago, on December 19, 1972, the Apollo 17 astronauts splashed down in the Pacific. They were the last humans to visit the Moon —and the last to be more than 400 miles from the Earth. Since that date, astronauts have only been in low Earth orbit.
It is thus richly symbolic that NASA’s Artemis I mission had its own Pacific splashdown recently, during Apollo 17’s 50th-anniversary celebration. It was, of course, only an uncrewed test of the space agency’s new lunar craft. Humans will not fly around the Moon for two to three years. Why has it taken more than five decades to send humans back to the Moon? It was certainly not Apollo 17 commander Eugene Cernan ‘s expectation when he stepped off the lunar surface for the last time on December 14, 1972,
He was aware, as was everyone in the space agency, that lean times were ahead. Two years earlier, NASA had deleted Apollos 18 and 19 to save money and focus on the Space Shuttle. Congress and two presidential administrations had been cutting NASA’s budget since 1967 as the Vietnam War, poverty, urban problems, and environmental crises made the space program less and less popular.
Once Neil Armstrong and Buzz Aldrin stepped on the surface in July 1969, many Americans wondered why we didn’t stop. We had beaten the Soviets and proved American technological superiority—the fundamental purpose of Project Apollo. Although the later landings yielded a huge scientific haul of samples and data, the public did not much care about lunar science’s value to understanding solar system history.
It seemed like a waste of billions of dollars to voters preoccupied with other problems. Thus, Cernan knew it could be two decades before a new human lunar program would be feasible. But it was hard to believe that American astronauts wouldn’t make it back before the end of the century. Apollo 17 landed on the Moon in the valley of Taurus-Littrow on December 11, 1972.

(Image courtesy of NASA) The Space Shuttle finally orbited in 1981, after thin NASA budgets and challenging new technologies caused years of delay.
- With a new, space enthusiast president in office, Ronald Reagan, NASA leadership set about pushing what they had always believed was the “next logical step” to a sustainable space infrastructure, a space station.
- The shuttle had been sold to the Nixon administration as a way to make spaceflight much cheaper (a promise never fulfilled), but it was originally supposed to be a crew and cargo transport vehicle to a permanent space base.
In late 1983, Reagan approved what eventually became the International Space Station (ISS). It fell to his successor, George H.W. Bush, to propose sending humans back to the Moon and on to Mars. Bush spoke on the steps of our Museum on July 20, 1989: the 20th anniversary of Armstrong and Aldrin’s historic first Moonwalk.
But his Space Exploration Initiative was short-lived. NASA’s 90-day study produced a politically toxic estimate of half a trillion dollars to establish a Moon base and land humans on Mars. Congress quickly lost interest. As it was, the agency was preoccupied with keeping the shuttle flying after recovering from the Challenger disaster of 1986, while advancing a space station project already years late and billions over budget.
The year 1990 saw major technical embarrassments, notably the discovery that the newly launched Hubble Space Telescope had a flawed mirror. Politicians and the media attacked NASA as bloated and bureaucratic, leading to cost overruns and failures. The collapse of the Soviet Union and the end of the Cold War also undercut one of the civil space program’s key rationales.
The space station came within one vote of being canceled in 1992 and was only politically safe after the Clinton administration merged it with the tottering Russian program to create the ISS in 1993-1994. Although the Cold War’s end ushered in an era of stagnant NASA budgets, it did have the ironic effect of saving the station, based on the argument that it would keep Russian rocket engineers from working for Iran, Iraq, or North Korea.
Going back to the Moon was not on the agenda. The Space Shuttle first orbited in 1981, after NASA budgets and challenging new technologies caused years of delay. Pictured here is Space Shuttle Discovery at the Steven F. Udvar Hazy Center. (Smithsonian Institution) The next attempt came after the second shuttle disaster, that of Columbia in 2003.
Criticisms of NASA, beyond those specific to the accident, focused on a human space program that seemed to have little direction beyond keeping the shuttle and ISS alive. In response, President George W. Bush announced the Vision for Space Exploration in early 2004. The shuttle would be phased out once the ISS was complete.
NASA would create new vehicles to go back to the Moon and on to Mars. Then, as now, the agency argued that we needed to develop at the Moon the experience and technology necessary to go to the Red Planet. NASA created the Constellation Program, which was to put Americans on the Moon by the 50th anniversary of Apollo 11—2019.
- But it was predicated on the shuttle program ending sooner than it did, freeing up money.
- Constellation was underfunded and soon fell behind schedule, producing cost overruns.
- President Barack Obama canceled it soon after coming into office.
- That leads us to the last, and in many ways, most unusual part of the story.
Constellation’s cancellation did not actually kill the human lunar program. Democratic and Republican senators, particularly those from states with NASA centers or industries tied to the human space program, banded together. They funded a giant booster and a spacecraft based on Constellation designs and shuttle technologies.
- Thus the Space Launch System (SLS) rocket and the Orion spacecraft emerged in the early 2010s.
- But they had no clear destination.
- Eventually, Congress directed NASA to build a small station in lunar orbit and develop the capability to land and create a Moon base.
- Under the Trump administration, the program got a name, Artemis (the sister of Apollo in Greek mythology), and a new objective: carry out a landing by 2024.
While that date was never realistic, it put Artemis on a path that has continued under the Biden administration. After 50 years, the United States again has a sustained program to send astronauts back to the Moon. Project Artemis gives the United States a sustained program to send astronauts back to the Moon, after 50 years. (Image courtesy of NASA) Why for over 40 years was there no such program and why has one emerged in the last decade? The answers are rooted in money, national prestige, and space program jobs.
Apollo’s success undercut the logic of a program based primarily on Cold War competition; the failure of the Soviets to send any cosmonauts to the Moon only reinforced the disinterest in more missions. In an era of cutbacks, just building a presence in low Earth orbit became NASA’s only feasible human spaceflight program.
The attempts of the two Bush presidencies to change that dynamic ran into a lack of support in the public and the political class for greatly increasing the agency’s budget. What changed after 2010? The shuttle program’s end in 2011 freed up budget money but threatened massive layoffs in NASA centers and the aerospace industry.
Congress wanted to sustain jobs in key states and felt that the human spaceflight program needed a higher purpose than just keeping ISS operational. Artemis has thus continued without a broad popular mandate or clear international competition, contradicting the pattern of the previous 40 years. China is mounting a space program that now includes robotic lunar and Mars probes, a permanent space station, and ambitions to build a Moon base.
Competition with a foreign power may again become a major factor in the future, helping to sustain Artemis, but has not been critical so far. The Orion spacecraft for the Artemis I mission successfully splashed down on December 11, 2022. (Image courtesy of NASA) How will the American public react when astronauts go back to the Moon? Undoubtedly with excitement, just as there was in the 1960s.
- But what happens afterward? Will the public quickly lose interest, as it did after Apollo, and even if that happens, will it matter? Is there now a political base to keep Artemis in business at some level? Given the pattern of the last decade, I would say yes.
- Whatever happens, I look forward to humans once again traveling to the Moon in the next few years, whether on Artemis II or SpaceX’s Starship, both of which may fly there by 2025.

How long will it take Artemis 3 to get to the Moon?
– The third Artemis mission will last 30 days, and is set to be the first human Moon landing since Apollo 17 in 1972. Four astronauts will fly to the Moon on board Orion, where they will dock with Gateway in orbit around the Moon. The Human Landing System will be designed by SpaceX and will be a lunar-adapted version of its reusable rocket Starship.
- Starship will take two astronauts down to the Moon’s South Pole, a region previously unvisited by humans.
- The two astronauts selected will be the first woman and first person of colour to land on the Moon.
- They will spend almost a week living in Starship and exploring the lunar surface, performing a variety of scientific studies including sampling water ice – first detected on the Moon in 1971.
Meanwhile, Orion and the remaining astronauts will complete one full orbit of the Moon, lasting 6.5 days, before being rejoined by their fellow crew from Starship. Artemis 3 projected flightpath | Source: NASA, July 2022
