NASA’s newest spacecraft concept looks like it belongs in a steampunk convention more than a distant moon, but that’s exactly where it’s supposed to be headed.

Steam power sounds like a relic of the Victorian era only glamorized by steampunk culture, but NASA is developing SPARROW (Steam Propelled Autonomous Retrieval Robot for Ocaen Worlds), a new steam-powered robot concept that could potentially unearth life on moons like Enceladus or Europa. Sure, our space agency might be known for the most cutting-edge technology, but even that could face potential disaster on frozen moons whose surfaces could be perilous. This relatively simple contraption is capable of doing things more complex robots can’t.

The flight computers and avionics of NASA’s Space Launch System (SLS) rocket’s core stage for the Artemis I mission were powered on and have completed a thorough systems checkout. The test used Green Run software that was developed for the test and loaded in the flight computers for the first time. The SLS avionics power on and checkout was the second of eight tests in the Green Run test series at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, where the core stage is installed in the B-2 Test Stand. The test steadily brought the core stage flight hardware, which controls the rocket’s first eight minutes of flight, to life for the first time. The three flight computers and avionics are located in the forward skirt, the top section of the 212-foot tall core stage, with more avionics distributed in the core’s intertank and engine section as shown in the right image. Engineers from NASA and Boeing, the core stage prime contractor, worked in control rooms as the avionic systems inside the Artemis I core stage, shown in the left image, were checked out. While this is the first time the Green Run software was used to control all the avionics in the flight core stage, engineers qualified the avionics and computers with earlier tests in the Systems Integration and Test Facility at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

The core stage will provide more than 2 million pounds of thrust to help launch Artemis I, the first in a series of increasingly complex missions to the Moon through NASA’s Artemis program. NASA is working to land the first woman and next man on the Moon by 2024. SLS is part of NASA’s backbone for deep space exploration, along with NASA’s Orion spacecraft, the human landing system, and the Gateway in orbit around the Moon.

“Even though we are living during unprecedented, challenging times, the spirit and resolute will of our country and all Americans has never been stronger.”

NASA Astronauts Chris Cassidy, Doug Hurley, and Bob Behnken, the three Americans living in space, paused this week to commemorate the nation’s 244th birthday. They shared this message, featuring the famous flag that flew on the first and last space shuttle missions and will be returned to Earth by Hurley and Behnken later this year.

Last fall, NASA unveiled the new suits that Artemis astronauts will wear when they take humanity’s first steps on the lunar surface for the first time since way back in 1972. The look of the A7LB pressure suit variants that accompanied those earlier astronauts to the Moon, and later to Skylab, has since gone on to signify for many the definitive, iconic symbol of humanity’s most ambitiously-realized space dreams.

With Artemis’ 2024 launch target approaching, NASA’s original Moon suit could soon be supplanted in the minds of a new generation of space dreamers with the xEMU, the first ground-up suit made for exploring the lunar landscape since Apollo 17’s Eugene Cernan and Harrison Schmitt took humanity’s last Moon walk (to date). Unlike those suits, the xEMU’s design is getting an assist from a source of “brain” power that simply wasn’t available back then: artificial intelligence.

The space-faring firm has completed its latest launch, and it means big things for the phone in your pocket.

NASA has completed the structural test campaign for NASA’s Space Launch System rocket at NASA’s Marshall Space Flight Center in Huntsville, Alabama. A test version of the rocket’s liquid oxygen tank was purposely pushed to its limits on June 22.

The final test concludes a nearly three-year structural test series that qualified the structural design of multiple hardware elements for the rocket that will launch NASA’s Artemis missions and astronauts to the Moon. WATCH go.nasa.gov/9312

Before NASA astronauts fly the Orion spacecraft on Artemis missions to the Moon and back, engineers needed to thoroughly test its ability to withstand the stresses of launch, climb to orbit, the harsh conditions of deep space transit, and return to Earth. NASA designed Orion from the beginning specifically to support astronauts on missions farther from Earth than any other spacecraft built for humans.

In June 2020, engineers completed testing on a duplicate of Orion called the Structural Test Article (STA), needed to verify the spacecraft is ready for Artemis I — its first uncrewed test flight. NASA and its prime contractor, Lockheed Martin, built the STA to be structurally identical to Orion’s main spacecraft elements: the crew module, service module and launch abort system.

The STA testing required to qualify Orion’s design began in early 2017 and involved 20 tests, using six different configurations — from a single element, to the entire full stack — and various combinations in between. At completion, the testing verified Orion’s structural durability for all flight phases of Artemis I.

SpaceX has gotten good enough at reuse that it’s building fewer rockets.
