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.

[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.

SLS: NASA proceeding with wet dress rehearsal next week after fuel temperature paused test

NASA is preparing to send the first woman and next man to the Moon in this decade with the Artemis program. Our return to the Moon won’t be like the Apollo program, however, as NASA wants to return in a sustainable fashion: lunar orbit station called gateway, Moon base called Artemis Base Camp, and international partnerships.

The agency briefly paused a critical step in testing the core stage of its new Space Launch System rocket at Stennis Space Center this week. NASA now says it will resume what’s called the wet dress rehearsal test next week. Launching NASA’s Space Launch System rocket and sending the Orion spacecraft around the Moon next year on the Artemis I mission is key to pushing forward with the Artemis program.

The team at the space center in South Mississippi briefly suspended fueling the rocket core stage on Monday after liquid oxygen temperature readings outside of the expected range were detected. Officials described the issue as operational and not caused by the rocket core stage. Now the team believes it has readjusted its fueling procedure to hit the target LOX delivery temperature.

Here’s the latest from NASA’s Artemis blog:

SLS core stage wet dress rehearsal paused for ‘days’ to adjust propellant loading procedure

NASA hopes to conduct a critical hot fire test of the core stage of its Space Launch System rocket at Stennis Space Center later this month. The test is the last major step in developing NASA’s new powerful rocket to the Moon. If all goes well this month, NASA will be on track to conduct its first lunar flyby mission called Artemis I with SLS and the Orion spacecraft as early as November 2021.

It’s too early to know if NASA will have to kick back the hot fire test into next year, but a scheduled wet dress rehearsal that started over the weekend was paused on Monday after initial propellant loading to the rocket. NASA says the team at Stennis Space Center will now study data collected during initial propellant loading and adjust the fueling process before completing the wet dress rehearsal.

NASA is GO for Space Launch System Wet Dress Rehearsal at Stennis Space Center

NASA conducted a readiness review from the teams at Stennis Space Center before the long-awaited Green Run Wet Dress Rehearsal (WDR) for Space Launch System’s core stage. The teams are all “Go” to begin the seventh and final test before teams ignite the four RS-25 engines (former Space Shuttle main engines) for a full duration burn strapped into the B-2 test stand in South Mississippi near Interstate-10 and the Louisiana state line.

Ultimately, the Wet Dress Rehearsal marks one of a few preliminary steps remaining before NASA launches its Artemis I mission in November 2021. Artemis I will be the first flight of Space Launch System, in which NASA’s new rocket sends its Orion spacecraft around the Moon for a lunar flyby mission. Artemis II will introduce astronauts to the lunar flyby route, and Artemis III will deliver the first woman and next man to the Moon.

Watch NASA’s mobile launcher rollout to Launch Pad 39B ahead of first Artemis lunar mission

NASA is returning astronauts to the Moon for the first time since the final Apollo mission took flight in 1972. The new Artemis program currently includes three missions starting with an uncrewed lunar flyby mission to test the Space Launch System (SLS) rocket and Orion spacecraft as soon as next year. The second Artemis spaceflight mission will introduce astronauts, and the third mission will make history as the first woman steps foot on the Moon.

Each Space Launch System rocket will lift off from Launch Pad 39B at Kennedy Space Center in Cape Canaveral, Florida. Today NASA’s Exploration Ground Systems team practiced moving the mobile launcher, a 380-foot-tall structure, to the launch pad where EGS will “complete a thorough top-to-bottom washdown, removing any FOD, or foreign object debris, as an added safety measure in addition to the walk downs performed prior to launch.”

Space Explored photographer Jared Base attended NASA’s sunrise mobile launcher rollout today and captured up-close shots and video of the 10.5 million pound structure traveling from the Vehicle Assembly Building to Launch Pad 39B.

NASA is returning to the Moon, but first a key component of its rocket must pass these tests

October 5: Six of eight steps have been completed. NASA plans to conduct the final step, an 8-minute long hot fire test, in November.

October 13: Boeing is tentatively planning the hot fire test for November 14.


Just north of Interstate I-10 along the Gulf Coast of Mississippi is a gigantic, orange core stage that will soon be used to send NASA’s most powerful rocket ever to the Moon. The 212-foot-tall core stage of Space Launch System, the vehicle for Artemis lunar missions starting next year, is currently hoisted up on the red, white, and meatball’d B-2 Test Stand at Stennis Space Center.

Engineers at the space center in south Mississippi are responsible for ensuring that the giant fuel tank and RS-25 engines are ready for action before being transferred to Kennedy Space Center in Florida. Steps range from testing flight electronics to loading and draining 350 tons of rocket fuel.

The ultimate step in the Green Run test is to fire up the four Aerojet Rocketdyne RS-25 engines fueled by the core stage. The static fire test will occur for up to eight minutes, creating a thunderous roar as the SLS core stage is held down by the B-2 Test Stand. Make no mistake: This engine test fire will be epic.

So how far along is NASA’s Green Run test for the Space Launch System core stage? Follow along here as NASA completes each step of the Green Run test:
