4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) By Wayne Smith Investigators at NASA’s Marshall Space Flight Center in Huntsville, Alabama, will use observations from a recently-launched sounding rocket mission to provide a clearer image of how and why the Sun’s corona grows so much hotter than the visible surface of Earth’s parent star. The MaGIXS-2 mission – short for the second flight of the Marshall Grazing Incidence X-ray Spectrometer – launched from White Sands Missile Range in New Mexico on Tuesday, July 16. NASA’s MaGIXS-2 sounding rocket mission successfully launched from White Sands Missile Range in New Mexico on July 16.…

These images from NASA’s LRO spacecraft show a collection of pits detected on the Moon. Each image covers an area about 728 feet wide. An international team of scientists using data from NASA’s LRO (Lunar Reconnaissance Orbiter) has discovered evidence of caves beneath the Moon’s surface. In re-analyzing radar data collected by LRO’s Mini-RF (Miniature Radio-Frequency) instrument in 2010, the team found evidence of a cave extending more than 200 feet from the base of a pit. The pit is located 230 miles northeast of the first human landing site on the Moon in Mare Tranquillitatis. The full extent of the cave is unknown, but it could stretch for miles beneath the mare. …

NASA/Eric Bordelon & Michael DeMocker On July 16, 2024, the first core stage of NASA’s SLS (Space Launch System) rocket for the agency’s Artemis II mission began a journey from NASA’s Michoud Assembly Facility in New Orleans. The core stage was moved onto the agency’s Pegasus barge, where it will be ferried 900 miles to NASA’s Kennedy Space Center in Florida. Once at Kennedy, engineers will prepare it in the Vehicle Assembly Building for attachment to other rocket and Orion spacecraft elements. The SLS rocket’s core stage is the largest NASA has ever produced. At 212 feet tall, it consists of five major elements, including two huge propellant tanks that collecti…

5 min read NASA: Life Signs Could Survive Near Surfaces of Enceladus and Europa Europa, a moon of Jupiter, and Enceladus, a moon of Saturn, have evidence of oceans beneath their ice crusts. A NASA experiment suggests that if these oceans support life, signatures of that life in the form of organic molecules (e.g. amino acids, nucleic acids, etc.) could survive just under the surface ice despite the harsh radiation on these worlds. If robotic landers are sent to these moons to look for life signs, they would not have to dig very deep to find amino acids that have survived being altered or destroyed by radiation. “Based on our experiments, the ‘safe’ sampling depth for…

“She gets things done.” This is how colleagues describe Brooke Weborg, machine learning data scientist and engineer at NASA. Weborg was nominated as Digital Transformer of the Month for her work on the AI/ML (artificial intelligence/machine learning) consultation portal, the type of ambitious project that computer scientist Herb Schilling had seen fail in the past. “Some of these things that you try to do just get bogged down in people saying no. But [Brooke] was never fazed by that at all…she just went ahead with it.” Reflecting on what makes Weborg a Digital Transformer, Schilling says, “A big part of digital transformation is communication, and she’s just a reall…

NASA-supported scientists have examined the long and intricately linked history of microbial life and the Earth’s environment. By reviewing the current state of knowledge across fields like microbiology, molecular biology, and geology, the study looks at how microorganisms have both shaped and been shaped by chemical properties of our planet’s oceans, land, and atmosphere. The study combines data across multiple fields of study and discusses how information on the complicated history of life on our planet from a single field cannot be viewed in isolation.

NASA’s VIPER – short for the Volatiles Investigating Polar Exploration Rover – sits assembled inside the cleanroom at the agency’s Johnson Space Center.Credit: NASA Following a comprehensive internal review, NASA announced Wednesday its intent to discontinue development of its VIPER (Volatiles Investigating Polar Exploration Rover) project. NASA stated cost increases, delays to the launch date, and the risks of future cost growth as the reasons to stand down on the mission. The rover was originally planned to launch in late 2023, but in 2022, NASA requested a launch delay to late 2024 to provide more time for preflight testing of the Astrobotic lander. Since that ti…
