NASA on track for SLS launch between August 23 and September 6 for Artemis I lunar mission

NASA conducted its fourth wet dress rehearsal attempt for its Space Launch System rocket this week, completing a critical trial run at fueling the rocket mostly without issue. Officials were uncertain one day after the test if the Moon rocket would require another round of fueling. The agency has since communicated that it intends to launch SLS as early as last August without a fifth go at working out the kinks during fueling.

NASA selects SpaceX to develop human landing system for Artemis moon mission using Starship

NASA is actively working on Artemis, a space exploration program that includes a mission to send the first woman and first person of color to the Moon during this decade. Astronauts will travel from Earth in NASA’s Orion spacecraft which will launch on the space agency’s Space Launch System rocket. SLS gives Orion the boost it needs to reach the Moon, but Orion doesn’t touch down on the lunar surface. A third vehicle called a human landing system is needed to transport astronauts to the surface of the Moon. One year ago, NASA selected three potential partners for providing the human landing system for Artemis 3, the first mission in the program that includes walking on the Moon.

Later today, the U.S. space agency will officially announce which partner it will proceed in funding for development. Ace Washington Post space reporter and author Christian Davenport has scooped the 4 p.m. EDT press conference with source selection details. According to Davenport, SpaceX has won the contract with its Starship-based human landing system bid.

Why did Space Launch System’s Green Run hot fire test abruptly end early? NASA can explain …

NASA released a statement this week detailing information about some of the findings that contributed to the early shutdown of the Artemis 1 Core Stage during the Green Run Hot Fire test on Saturday.

[UPDATED] NASA’s upgraded mobile launcher for larger Space Launch System rocket moving forward

NASA recently submitted a permit detailing facility construction and modification plans to support its next Mobile Launch Platform for Space Launch System, the agency’s nearly complete rocket to the Moon. We first have to go back to where SLS all started with the Constellation program to understand why NASA is building a new Mobile Launch Platform.

The current Mobile Launcher, ML-1, was initially built for the Constellation program between 2009 and 2010. When the Constellation program was canned in October 2010, NASA started reworking ML-1 to support their new program for the Space Launch System. With the increased complexity and weight of SLS, issues quickly began to arise.

SLS: Green Run engine test ends early, likely pushing back first Artemis Moon mission [Gallery]

NASA is returning astronauts to the Moon for the first time since the Apollo program ended in the 1970s, but first the space agency must develop a new rocket capable of reaching lunar orbit. Space Launch System is that rocket, and it’s been in development for several years.

Over the weekend, NASA’s Stennis Space Center in South Mississippi conducted a critical engine test on the core stage of Space Launch System and its four RS-25 engines. While these engines aren’t new — they actually date back to use on the space shuttle — but being configured on a rocket to the Moon is untested.

The epic engine test wasn’t a total success, however, as the vehicle detected an anomaly and stopped firing its engines well before the required test duration. The good news is NASA says both the rocket core stage and its engines remain in good shape.
