The space agency is already testing the Orion spacecraft, a capsule designed by Lockheed Martin that is expected to deliver astronauts there. Plans are also underway for an orbiting space station called the Lunar Gateway, which could serve as a base of operations for astronauts shuttling to and from the lunar surface.

CU Boulder’s Jack Burns, who served on the Trump administration’s NASA transition team and was present for Pence’s pledge, has been waiting a long time for this moment — not for the sake of adventure or geopolitics, but for science. He envisions humans living and working on the moon, using it as a platform for seeing the cosmos’ origins.

“When I hear people say ‘been there, done that for science on the moon, I tell them ‘You are nuts,’” said Burns, a professor of astrophysical and planetary sciences who also directs the NASA-funded Network for Exploration and Space Science at CU. Read more...
