The mission, which is named after the Greek goddess of hunting, wilderness and the moon, will follow-on from Apollo - a six flight program that put 12 men on the moon 50 years ago.
Artemis 3 would bring astronauts to the orbiting mini-station in 2024 prior to a lunar surface and return to Gateway.
A top NASA official appointed head of strategy for the space agency's planned mission to the moon in 2024 quit his role on Wednesday, just weeks after starting the job.
NASA on Thursday unveiled the calendar for the "Artemis" program that will return astronauts to the Moon for the first time in half a century, including eight scheduled launches and a mini-station in lunar orbit by 2024. Following the completion of the power and propulsion element, habitation, logistics and airlock capabilities will be added.
The program will also test claims about how the Apollo 1 fire started; study one of NASA's last existing Lunar Lander prototypes that Neil Armstrong trained on; gain access to NASA archives to uncover photos and footage never-before-seen by the general public, and more.
The rest of the new money will go towards ensuring that Nasa's SLS rocket and Orion crew capsule are developed on time; that robotic explorations of the moon's south pole prepare the way for human landings; and that new technology can be developed that will allow resources such as water to be "mined" from the moon.
Even if the official naming of these companies is a late action, NASA had the basis for it ever since April, when they sent out what they call 'pre-solicitations.' The first pre-solicitation disclosed NASA's plan to ask for suggestions from companies to create the ascent element on the next lunar lander.
Sirangelo "was escorted out of NASA's headquarters in Washington" after he resigned, according to two sources who spoke to Reuters, "to pursue other opportunities". NASA will not specify it in every detail but instead will buy it as a service, Bridenstine said. Aerospace giants such as Boeing and Lockheed Martin are vying for the contract as are new players like Jeff Bezos' Blue Origin. "2024 is right around the corner".
