NASA tweaks require lunar landing concepts



WASHINGTON – NASA has updated a planned call for proposals for Lunar Landers to enable a human mission in 2024 and to extend its scope to include integrated lander concepts.

In a complaint released on April 26, NASA has updated an earlier announcement released on April 8, plans to call for proposals for an ascent stage for a human-rated Moon Lander. Instead, the upcoming procurement process will seek proposals for a "fully integrated landing craft" that includes a promotion module, a descent module, and a transfer phase.

A formal call for proposals, which is part of NASA's Next Space Technologies for Exploration Partnership (NASA) NextSTEP program, and officially known as Appendix H, has yet to be published by the agency. NASA said on the NextSTEP website that it is expected to publish such a call by the end of May, covering both studies and vehicle development options.

"NASA will seek proposals from the US industry for development, integration and occupation demonstrating these elements as a functional human land system that can meet the requirements of NASA and industry," the agency said. Until the appointment of humans on the moon in 2024.

Prior to announcing Vice President Mike Pence on March 26, he called for a Human Moon Landing In five years, NASA embarked on a two-pronged approach to the development of lunar human strains. In February, it issued a separate call to investigate transfer vehicles and descent stages, also referred to as part of NextSTEP and designated as Appendix E. NASA said it would lead studies of the ascent phase within the agency.

Following Pence's speech, NASA changed course and announced plans for promotion work in the April 8 announcement. NASA Administrator Jim Bridenstine said in a speech at the 35th Space Symposium in Colorado Springs on April 9 that the message was developed within a week. He added that he expected the lunar landing systems to be built as public-private partnerships.

The updated plans provide a second chance for those who did not attend the earlier Lander Student Application or did not receive any awards. "Suppliers of Annex H who are not prize winners in Annex E will be given the opportunity to suggest similar work, as required for their proposals in Annex H," NASA said in the revised procurement documents.
