\n As he took his final steps before leaving the moon, Apollo 17 commander Gene Cernan had some poignant closing words<\/a>: \u201cWe leave as we came, and, God willing, as we shall return, with peace and hope for all mankind.\u201d\n <\/p>\n

\n It was December 14, 1972, and Cernan knew his footprints would be the last to impress the lunar soil for a while, because the planned Apollo missions that were supposed to follow \u2014 18, 19 and 20 \u2014 had long since been canceled. But he probably wouldn\u2019t have guessed that, over 50 years later, his speech would stand as the last words spoken by a human on the moon.\n <\/p>\n

\n Artemis II<\/a>, which NASA is preparing to launch as soon as March after recent testing delays, will perform a lunar fly-by rather than a landing. Still, the mission will mark humanity\u2019s first journey to the vicinity of the moon since Apollo 17.\n <\/p>\n

\n So why has it taken so long for astronauts to go back?\n <\/p>\n

\n \u201cThe short answer to that question is political will,\u201d said Teasel Muir-Harmony, a historian of science and technology and the curator of the Apollo Collection at the Smithsonian National Air and Space Museum in Washington, DC. \u201cIt takes a whole lot of political will to send humans to the moon. These are extremely complex, really costly, major national investments. It has to be a priority over a sustained period of time.\u201d\n <\/p>\n

\"Earth<\/p>\n

\n In the years since the Apollo program ended due to budget cuts, there have been a number of other federal initiatives to send humans to the moon again, Muir-Harmony added. \u201cBut what\u2019s happened is that as presidential administrations changed, space priorities for these large-scale programs also changed. And so we just haven\u2019t seen the sustained political will to follow through with a program that will take many years, significant funding and lots of resources in general.\u201d\n <\/p>\n

\n Les Johnson, a former NASA chief technologist who worked at the agency for over three decades, agreed that rapidly changing political objectives have been a key factor: \u201cEvery four to eight years, NASA has its human spaceflight goals and objectives completely, totally, radically altered,\u201d he said.\n <\/p>\n

\n \u201cWhen I joined NASA in 1990, we were directed to go back to the moon by then President George H.W. Bush. But when President Clinton took office in 1993, he canceled that. He said, we\u2019re going to make the space station happen \u2014 don\u2019t do anything associated with going back to the moon,\u201d Johnson said. \u201cWe did that for eight years, and then in 2001 we got George W. Bush, and he said, cancel all this other stuff and let\u2019s focus on going back to the moon. So we did, and a project called Constellation was born, which survived the two terms of the second Bush presidency.\u201d\n <\/p>\n

\n The cycle continued with Barack Obama moving NASA\u2019s priorities more toward sampling asteroids, and President Donald Trump coming in and shifting back to lunar goals. Then, after 2020, Joe Biden broke up the pattern.\n <\/p>\n

\n \u201cHe was the first president in my career at NASA who did not change everything,\u201d Johnson said of Biden. \u201cHe said, I really didn\u2019t like a lot of what Trump did, but I think going back to the moon is a good idea. Let\u2019s just keep going.\u201d Now, in Trump\u2019s second term, his administration has recently doubled down on returning astronauts to the lunar surface \u2014 intent on outpacing China in the new space race.\n <\/p>\n

\n Political hurdles aside, however, moon missions also present a remarkable technical challenge<\/a>. Earth\u2019s natural satellite is roughly a quarter of a million miles (over 400,000 kilometers) away, and over half of all lunar landing attempts have ended in failure. The Artemis program \u2014 making use of a rocket and spacecraft that have taken two decades and more than $50 billion to complete \u2014 is NASA\u2019s latest and most promising attempt to bring such feats within reach.\n <\/p>\n

\n Many similarities between Apollo and Artemis are undeniable, including a near match in the mission profile between Apollo 8 and Artemis II, but re-creating the Apollo program today wouldn\u2019t have been a practical \u2014 or logical \u2014 option.\n <\/p>\n

\n Long gone are the supply chains and skilled machinists that built the hardware for those mid-20th century moon missions.\n <\/p>\n

\"Apollo<\/p>\n

\n \u201cPeople ask what was wrong with Apollo,\u201d Wayne Hale, a former NASA space shuttle program manager, previously said during a Human Exploration and Operations Committee meeting<\/a>. \u201cThe thing that was wrong with Apollo was it ended.\u201d\n <\/p>\n

\n One oft-mentioned<\/a> piece of Apollo lore is that the program\u2019s spacecraft and rockets were controlled by computers less powerful than a modern smartphone. And NASA has put many of those advancements to use, particularly when it comes to the robotic exploration<\/a> of other worlds.\n <\/p>\n

\n But spaceflight \u2014 and human spaceflight in particular \u2014 is far too complex, dangerous and expensive to directly translate computing advancements to easier, cheaper moon missions.\n <\/p>\n

\n The technology regular folks interact with on Earth also has the benefit of being tested by millions of users and improved over decades of mass production.\n <\/p>\n

\n Complex missions to deep space, however, require multibillion-dollar contracts and years of continuous work toward the same goal \u2014 a scenario that has been hard to come by in the years since Apollo as presidential administrations have stopped and started various flagship human exploration programs.\n <\/p>\n

\n The Artemis program is the most successful moon program the United States has had in decades, noted Casey Dreier, the chief of space policy at The Planetary Society, a nonprofit exploration advocacy group \u2014 \u201cbecause it still exists.\u201d\n <\/p>\n

\n At the technical level, the differences<\/a> between the Apollo and Artemis spacecraft are vast. For starters, Orion\u2019s flight computers are 20,000 times faster and possess 128,000 times more memory than the lone machine that guided Apollo.\n <\/p>\n

\"Buzz<\/p>\n

\n The Orion capsule offers the crew \u2014 increased from three to four \u2014 more space and opportunities for exercise and entertainment. And a much better toilet. \u201cWith the Apollo program, the astronauts had a waste collection device which was like a plastic bag with a rim, and they would stick it upon themselves. Not the most pleasant experience,\u201d Muir-Harmony said.\n <\/p>\n

\n Aboard Orion, which has about a third more habitable space than Apollo, the crew will enjoy the luxury of a real bathroom. \u201cIt\u2019s a little room tucked into the spacecraft that they can go inside,\u201d Muir-Harmony said. \u201cIt looks like a little closet or a little phone booth. It\u2019s small, but there\u2019s some privacy, which is pretty essential when you have a crew that\u2019s both men and women.\u201d\n <\/p>\n

\n During the Apollo era, she added, the bathroom issue was part of the discussion around whether women should be astronauts. \u201cThe Soviet program had a woman fly in space 20 years before the United States did. But some people said that designing bathroom technology for women in space was going to be too complicated,\u201d Muir-Harmony said. \u201cYou can debate that, but it is important to think through privacy when you have a crew of both men and women, and so they were able to achieve that with the design of the Orion spacecraft.\u201d\n <\/p>\n

\n In-space bathrooms have come a long way since Apollo. The International Space Station, for example, has a comparatively spacious stall for washing and using the toilet. And the SpaceX Crew Dragon capsule<\/a>, which since 2020 has transported astronauts to and from the orbiting laboratory, has a small private area with a vacuum toilet.\n <\/p>\n

\"Scientist-astronaut<\/p>\n

\n The goals of the two programs are also markedly different. Apollo already accomplished the one-off \u201cflags and footprints\u201d missions, Hale said.\n <\/p>\n

\n Now, NASA wants to create the infrastructure that will allow astronauts to live and work at a lunar base \u2014 eventually creating a sustainable, permanent human presence on the moon.\n <\/p>\n

\n \u201cThat means the landers that are being developed are designed to remain for longer than a day. They\u2019re meant to be a part of a bigger architecture or system that will eventually have habitats on the moon,\u201d Johnson said, adding that while the upcoming flight of Artemis II is reminiscent of Apollo 8, the programs will diverge dramatically after that.\n <\/p>\n

\n The rise of the commercial space industry has helped fuel this decisive push toward revamping moon plans, according to Brian Odom, NASA\u2019s chief historian.\n <\/p>\n

\n \u201cNASA is now a customer to a private industry where we have SpaceX, Boeing, Blue Origin. That\u2019s an enabling factor that\u2019s helped us,\u201d Odom said.\n <\/p>\n

\n SpaceX is among the biggest of those partners, and its CEO, Elon Musk, recently announced a dramatic shift<\/a> in the company\u2019s focus from prioritizing sending humans to Mars to first building \u201ca self-growing city on the Moon.\u201d\n <\/p>\n

\"An<\/p>\n

\n However, Odom added, getting back to the moon has always been dependent on a number of pieces falling into place. \u201cSpace is very difficult and requires a lot of different things coming together at one time. Commercial commitments, international commitments and now the government \u2014 all three working together, is what\u2019s really enabled us to get to this point,\u201d he said.\n <\/p>\n

\n \u201cIt\u2019s been a long road, but going back has always been a strategy, and it\u2019s emerged in a couple of different moments. Now we have the infrastructure in place, we have partners in place \u2014 and it\u2019s becoming possible.\u201d\n <\/p>\n

\n Crucially, prolonged human presence on lunar soil will also benefit from the experience gained through the programs that followed the Apollo era, such as the International Space Station, where humans have had a permanent presence for over 25 years.\n <\/p>\n

\n \u201cReturning to the moon will require long-term stays on the lunar surface, and thus understanding the effects of space habitation on the human body,\u201d said James W. Head, a research professor of Earth, environmental and planetary sciences at Brown University who worked on the Apollo program.\n <\/p>\n

\n \u201cAnd robotic missions flown in the interim, such as NASA\u2019s Lunar Reconnaissance Orbiter<\/a>, have provided information on where to go and find the resources necessary to support human presence, indicating the possibility of water resources trapped at the lunar poles.\u201d\n <\/p>\n

\n And if world leaders need extra motivation, Head added, they should look to the words of Apollo 16 Commander John Young, who was asked before retiring in 2004 what the point was of spending money to go to the moon. \u201cEarth\u2019s geologic history is pretty clear: It says, quite frankly, that single-planet species don\u2019t last,\u201d Young said<\/a>.\n <\/p>\n

\n The Apollo program had to contend with the deadline imposed by President John F. Kennedy, who in 1961 declared to Congress his goal to land a man on the moon before the decade was out. He wanted to beat the Soviet Union, which had already put a satellite and a man in orbit before the US.\n <\/p>\n

\"Wernher<\/p>\n

\n \u201cA critical element to understanding the early space race and why the United States sent humans to the moon was the Cold War context, and the competition for the hearts and minds of the world,\u201d Muir-Harmony said. \u201cThe United States was quite worried about Soviet influence, especially in newly established countries. Space exploration was seen as a really important tool of influence internationally.\u201d\n <\/p>\n

\n Today, the United States considers China to be its archrival, and the government has sought allies to sign onto its vision of the future of lunar exploration with a set of international agreements called the Artemis Accords, which over 60 nations have now joined.\n <\/p>\n

\n The nonbinding accords outline a safe, peaceful and sustainable approach to civil space exploration. They build upon the existing 1967 Outer Space Treaty<\/a>, which states that no nation can claim territory in space as its own or use it to harbor weapons of mass destruction. However, the Artemis Accords<\/a> were not negotiated multilaterally in the same manner as the Outer Space Treaty, and some analysts argue that they violate some of its principles, for example by allowing commercial mining on the moon.\n <\/p>\n

\n Going back to the moon for a long-term presence and building an infrastructure in the lunar environment wouldn\u2019t be sustainable for a single country, Odom said. \u201cI think that\u2019s what makes the Artemis Accords so good \u2014 they create a framework for opportunity, but they also double down on the idea that this is for humanity, not just one nation.\u201d\n <\/p>\n

\n However, even though no other country has ever come close to sending a crewed mission to the moon, China also has concrete plans to do so by 2030 \u2014 and is not a signatory of the Artemis Accords.\n <\/p>\n

\n \u201cThere may be a perception that the US is in a race with China to the moon,\u201d Odom said.\n <\/p>\n

\n \u201cMaybe there\u2019s a second space race, but I think that\u2019s always going to be balanced with understanding risk, something that had become problematic in the early years of Apollo, when the idea that you had to do it before the end of the decade became a primary driver, and may have cost the lives of three crewmen,\u201d he added, referring to the Apollo 1 accident in 1967 that killed all three crew members as a fire broke out in the cabin during a launch rehearsal.\n <\/p>\n

\n Since Apollo, Odom noted, the Challenger and Columbia disasters also cemented a more grounded approach to risk: \u201cWe\u2019ve learned so many lessons the hard way, and now those lessons are being applied.\u201d\n <\/p>\n
