Sizing up the contenders for NASA’s lunar-lander program

For the first time in a dog's age, NASA's human spaceflight program seems to be in a hurry. Although few in the aerospace industry expect the agency to meet its 2024 goal of landing humans on the South Pole of the Moon, this deadline has nonetheless spurred the space agency to move quickly with contracts on offer for a lunar space station, spacesuits, Moon cargo delivery, and more.

And then there is the space agency's grand prize. At the end of September, NASA asked industry to bid for large contracts-which eventually will be worth at least several billion dollars-to build a "human landing system" that will take astronauts from lunar orbit down to the Moon's surface. There is a lot to digest in these documents, which entail three-dozen attachments and several amendments. But now the time has nearly expired-the deadline for companies to respond is November 5.

These are hugely consequential contracts. If NASA's return to the Moon survives into future presidential administrations, the company that builds a human lunar lander will earn both prestige for landing astronauts on another world, but also potentially long-term contracts that may one day include landing humans on Mars.
