NASA’s Artemis II mission, which is scheduled for launch on 1 April, aims to send humans back to the Moon for the first time since 1972. If all goes to plan, the ten-day mission will see a crew of four astronauts fly by the Moon as soon as 6 April, and could set the record for the farthest a human has ever travelled from Earth.
The mission’s main goals are to test aspects of human space flight ahead of future, more complex missions. So far, however, Artemis II and its scientific projects, which range from geology to astronaut health, have yet to spark widespread enthusiasm among researchers. “A fly-by makes sense to demonstrate the systems before attempting a landing,” says Marc Norman, a planetary geochemist at the Australian National University in Canberra. But he says he is “not especially excited at this stage”. “Maybe my excitement level will increase as the program evolves,” he adds.
Human space flight is a major focus for US President Donald Trump’s administration, which has sought to accelerate some projects, including an effort to send astronauts to Mars, while also making cuts to NASA’s space science and robotic missions. Earlier this year, the agency announced an ambitious goal of landing astronauts on the Moon in 2028, and starting to build a permanent lunar base soon after that.
Ahead of Artemis’s launch, Nature asked researchers worldwide for their views on the upcoming mission, and why they will — or won’t — be watching the lunar fly-by.
The good
“On the science side, this is one of the first steps in a very long-term plan to get a human base on the Moon,” says Catherine Heymans, Astronomer Royal for Scotland in Edinburgh, UK. “The science that will be facilitated by making that happen is very exciting.” Although the mission will produce some research results, its greatest value for now will be in inspiring young people about science, and in showing — by including a Black man, Victor Glover, and a woman, Christina Koch, among the crew — that “space is for everyone”, she adds.
John Womersley, a former chief executive of the UK Science and Technology Facilities Council who is now at the University of Edinburgh, says that scientists, like the general public, have a wide range of opinions about Artemis II and crewed space exploration in general. “Among my colleagues now, though, there is some genuine admiration for the fact that NASA is actually trying to do something ambitious in space once more, and going beyond low Earth orbit.”
Jevin West, a computational social scientist at the University of Washington in Seattle, agrees. “In times like this, these are the things that can give us a reprieve,” he says.
