Nasa is turning to the private sector in hopes it can build the first lunar landers for astronauts in half a century.
Three competing designs have been made with one ultimately chosen to return humans to the moon.
Nasa administrator Jim Bridenstine announced this week that the companies that will develop, build and fly the lunar landers, with the goal of returning astronauts to the moon in 2024 and ultimately on to Mars.
The companies are SpaceX in Hawthorne, California, led by Elon Musk; Blue Origin in Kent, Washington, founded by Amazon’s Jeff Bezos; and Dynetics, a Huntsville, Alabama, subsidiary of Leidos.
‘This is the last piece that we need in order to get to the moon’ by 2024, Mr Bridenstine said.
He noted it will be the first lunar lander since the last Apollo moon mission in 1972.
Over the next 10 months, each company will refine its concept and Nasa will decide which lander to test first.
Mr Bridenstine said Nasa will go with the company that has the highest probability of success by 2024.
Nasa will rely on its own Orion capsules and Space Launch System megarockets – still under development – to launch astronauts to the moon.
The two other companies, Boeing and Vivace, put in bids but were eliminated early on, leaving the three awarded contracts.
SpaceX’s proposed Starship lander is so tall that astronauts will use an elevator to get to and from the lunar surface.
Blue Origin’s version comes with a big ladder, according to artistic renderings. The Dynetics lander is so low to the ground that only a few steps are needed, like a front porch, a feature that Nasa gave high marks for safety and efficiency.
SpaceX is using its own Starship spacecraft – still under development in Texas – and its own rockets. Blue Origin and Dynetics are partnering with numerous subcontractors, including commercial launch companies.
Going commercial, Mr Bridenstine said, will drive down costs while increasing access.
It builds off of Nasa’s commercial cargo and crew programs for the International Space Station.
Just last November, SpaceX and Blue Origin were among the companies that won contracts to make cargo deliveries to the moon.
Nasa wants the new Artemis moon-landing programme to be sustainable, unlike Apollo, with multiple missions and multiple locations on the lunar surface.
While only one company will carry the first woman and next man to the lunar surface, all three will participate over the long haul, officials noted.
By learning how to live and work on another world – the moon – Nasa will be better equipped to eventually send astronauts to Mars, Mr Bridenstine said.
