How the Apollo 11 Moon Landing Worked (Infographic)

Landing 12 people on the moon remains one of NASA's greatest achievements, if not the greatest. Astronauts collected rocks, took photos , performed experiments , planted flags , and then came home. But those stays during the Apollo program didn't establish a lasting human presence on the moon. More than 45 years after the most recent crewed moon landing — Apollo 17 in December — there are plenty of reasons to return people to Earth's giant, dusty satellite and stay there.

Vice President Mike Pence has promised that we will see US astronauts on the moon by including the first women to ever touch the lunar surface , in a program called Artemis.

But on a recent phone call with reporters, NASA Administrator Jim Bridenstine said that ambitious goal is going to require quite a lot more federal cash, something that's historically been a political sticking point in Washington.

Apollo 9 astronaut Rusty Schweickart recently told Business Insider that he wishes Bridenstine "good luck" with this goal. Researchers and entrepreneurs have long pushed for the creation of a crewed base on the moon — a lunar space station. It's only three days away. We can afford to get it wrong and not kill everybody," Chris Hadfield, a former astronaut, previously told Business Insider.

A lunar base could evolve into a fuel depot for deep-space missions , lead to the creation of unprecedented space telescopes , make it easier to live on Mars , and solve longstanding scientific mysteries about Earth and the moon's creation. It could could even spur a thriving off-world economy, perhaps one built around lunar space tourism.

But many astronauts and other experts suggest the biggest impediments to making this and moon missions in general a reality are banal and somewhat depressing. Bloomsbury Auctions. A tried-and-true hurdle for any spaceflight program, especially missions that involve people, is the steep cost. Those amounts may sound like a windfall, until you consider that the total gets split among all the agency's divisions and ambitious projects: the James Webb Space Telescope , the giant rocket project called Space Launch System SLS , and far-flung missions to the sun , Jupiter , Mars , the asteroid belt , the Kuiper belt , and the edge of the solar system.

Trump's budget calls for a return to the moon , and then later an orbital visit to Mars. But given the ballooning costs and snowballing delays related to NASA's SLS rocket program, there may not be enough funding to make it to either destination, even if the International Space Station gets defunded early.

He added, according to Scientific American : "Unless the country, which is Congress here, decided to put more money in it, this is just talk that we're doing here.

Referring to Mars missions and a return to the moon, Cunningham said, "NASA's budget is way too low to do all the things that we've talked about. US President Donald Trump. If the Trump administration succeeds in landing astronauts back on to the moon in , that would come at the tail end of what could be Trump's second term, if he gets reelected. The process of designing, engineering, and testing a spacecraft that could get people to another world easily outlasts a two-term president.

But incoming presidents and lawmakers often scrap the previous leader's space-exploration priorities. In , for example, the Bush administration tasked NASA with coming up with a way to replace the space shuttle, which was set to retire, and also return to the moon.

The agency came up with the Constellation program to land astronauts on the moon using a rocket called Ares and a spaceship called Orion. Trump hasn't scrapped SLS. But he did change Obama's goal of launching astronauts to an asteroid , shifting priorities to moon and Mars missions. I'll just see things as they come. Buzz Aldrin said in testimony to Congress in that he believes the will to return to the moon must come from Capitol Hill. We demonstrated that for a brief time 45 years ago.

I do not believe we have done it since," Aldrin wrote in a statement. The real driving force behind that government commitment to return to the moon is the will of the American people, who vote for politicians and help shape their policy priorities. But public interest in lunar exploration has always been lukewarm. Others who want the US to land on the moon say robots could do the lunar exploring.

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. 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. Its surface is littered with craters and boulders that threaten safe landings. Leading up to the first moon landing in , 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 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 days, previously told Business Insider that the Apollo missions "had a lot of problems with dust. 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. NASA has designed dust- and sun-resistant spacesuits and rovers , though it's uncertain whether that equipment is anywhere near ready to launch.

Today, more American kids polled say they dream about becoming YouTube stars, rather than astronauts. Schweickart echoed that concern, noting that the average age of someone today at NASA's Johnson Space Center is closer to 60 years old.

Excitement comes from when you've got teenagers and year-olds running programs," Schweickart said. Musk is part of what astronaut Jeffrey Hoffman has called a "generation of billionaires who are space nuts," developing a new, private suite of moon-capable rockets.

Many astronauts' desire to return to the moon aligns with Bezos' long-term vision. Bezos has floated a plan to start building the first moon base using Blue Origin's upcoming New Glenn rocket system. Musk has also spoken at length about how SpaceX's forthcoming Starship launch system could pave the way for affordable, regular lunar visits. Someday I think the moon will be, and that's something to work for.

Astronauts don't doubt whether or not we'll get back to the moon and onto Mars. It's just a matter of when.

Dave Mosher and Hilary Brueck. Over the decades, NASA has planned to send people back to the moon but has yet to succeed. The Trump administration wants to get astronauts back there by Astronauts often say the reasons humans haven't returned to the lunar surface are budgetary and political hurdles, not scientific or technical challenges.

Private companies like Blue Origin and SpaceX may be the first entities to return people to the moon. Visit Business Insider's homepage for more stories.

8 Little-Known Facts About the Moon Landing

Armstrong and Aldrin stayed on Moon for just more 21 hours-two-and-a-half hours of which were spent outside the Lunar Module exploring and conducting scientific experiments. At pm on July 21 the astronauts lifted off from the Moon in the module's ascent stage and then rendezvoused with Collins and the orbiting spacecraft. The three explorers fired away from lunar orbit on July 22 and returned to Earth on July Armstrong and Edwin E.

Launched from Earth on July 16, , the three astronauts of Apollo 11 arrived in orbit of the moon on July Mission Commander Neil A. Armstrong was born Aug.

At p. ET on July 24, , the Columbia capsule splashed down miles southwest of Hawaii, ending the historic Apollo 11 mission. On July 20, , the U. After a series of embarrassing defeats at the hands of the Soviets, the engineering marvel that was the Saturn V had captured victory through brute force, taking three Americans to lunar orbit, and successfully depositing two on the surface below. For many Americans, it was a day of celebration, but for the three men that had secured victory—Neil Armstrong, Buzz Aldrin, and Michael Collins—the challenges were far from over.

The Art of the Return Trip: How NASA Got Apollo 11 Home

Apollo 11 was the spaceflight that first landed humans on the Moon. Armstrong became the first person to step onto the lunar surface six hours and 39 minutes later on July 21 at UTC; Aldrin joined him 19 minutes later. They spent about two and a quarter hours together outside the spacecraft, and they collected Command module pilot Michael Collins flew the Command Module Columbia alone in lunar orbit while they were on the Moon's surface. Armstrong and Aldrin spent 21 hours, 36 minutes on the lunar surface at a site they named Tranquility Base before lifting off to rejoin Columbia in lunar orbit.

It was a feat for the ages. Along the way to achieving JFK's vision, there was plenty of hard work, drama and surprise.
