NASA Mega Moon Rocket Passes Key Test, Readies For Launch
The largest rocket element NASA has ever built, the core stage of NASA’s Space Launch System (SLS) rocket, fired its four RS-25 engines for 8 minutes and 19 seconds Thursday at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
The successful test, known as a hot fire, is a critical milestone ahead of the agency’s Artemis I mission, which will send an uncrewed Orion spacecraft on a test flight around the Moon and back to Earth, paving the way for future Artemis missions with astronauts.

NASA Analysis: Earth Is Safe From Asteroid Apophis for 100-Plus Years
After its discovery in 2004, asteroid 99942 Apophis had been identified as one of the most hazardous asteroids that could impact Earth. But that impact assessment changed as astronomers tracked Apophis and its orbit became better determined.
Now, the results from a new radar observation campaign combined with precise orbit analysis have helped astronomers conclude that there is no risk of Apophis impacting our planet for at least a century.

Space Debris Removal Demonstration Launches
Among the payloads was a 500kg Earth imager developed by the South Korean space agency; and a pair of spacecraft from the Tokyo-headquartered Astroscale company which will give a demonstration of how to clean up orbital debris.
Astroscale’s showcase will be run from an operations centre in the UK. The Soyuz flight lasted nearly five hours following a 06:07 GMT lift-off.
The long duration was a consequence of having to put so many different satellites in three different orbits roughly 500km to 550km above the Earth.

Static Test Of SSLV’s First Stage Solid Motor Unsuccessful: ISRO
The static test of first stage solid motor (SS1) of ISRO’s Small Satellite Launch Vehicle (SSLV) — a new-generation compact rocket — was not successful, according to sources in ISRO. “Oscillation was noticed after 60 seconds into the test and nozzle was blown out near the bucket flange where it’s attached with the motor at around 95 seconds”, sources in the Bengaluru-headquartered space agency said. It was supposed to be tested for a total duration of about 110 seconds, officials said.

SPACE HAZARDS AND STM
Decommissioned NOAA Weather Satellite Breaks Up
A polar-orbiting weather satellite decommissioned nearly eight years ago has broken up, adding to the growing debris population in a key orbit.
The Space Force’s 18th Space Control Squadron said March 18 it hard confirmed the NOAA-17 satellite broke up March 10. The squadron said it was tracking 16 pieces of debris associated with the satellite, and that there was no evidence the breakup was caused by a collision.

Suspected Space Junk From Satellite Launch Puts On Light Show Over Southern B.C.
A cluster of bright, falling lights lit up the skies over B.C.’s South Coast and much of the U.S. Pacific Northwest on Thursday night, the suspected result of rocket debris burning up as it re-entered the atmosphere.
Videos of the phenomenon were posted on social media by residents of the Seattle area, Oregon and B.C.
On Vancouver Island, the Saanich Fire Department tweeted that it had “received reports of flames in the sky” from multiple callers.

Algorithms Inspired By Social Networks Reveal Lifecycle Of Substorms, A Key Element Of Space Weather
Space weather often manifests as substorms, where a beautiful auroral display such as the Northern Lights is accompanied by an electrical current in space which has effects at earth that can interfere with and damage power distribution and electrical systems. Now, the lifecycle of these auroral substorms has been revealed using social media-inspired mathematical tools to analyse space weather observations across the Earth’s surface.
Analysis by researchers led by the University of Warwick has revealed that these substorms manifest as global-scale electrical current systems associated with the spectacular aurora, reaching across over a third of the globe at high latitudes.

New Imaging Algorithm Can Spot Fast-Moving And Rotating Space Junk
A new imaging algorithm devised by researchers in the US could improve our ability to track space junk orbiting the Earth. Through simulated tests, the team has showed how a cross-correlation of the signals reflected by a piece of debris could be used to extract high-resolution, undistorted images of how an object spins as it travels through space – allowing it to be tracked more accurately. Their algorithm could soon prove invaluable in protecting satellite systems from colliding with space junk.

Water Mission Takes On Space Weather
For well over a decade, ESA’s SMOS satellite has been delivering a wealth of data to map moisture in soil and salt in the surface waters of the oceans for a better understanding of the processes driving the water cycle. While addressing key scientific questions, this exceptional Earth Explorer has repeatedly surpassed expectations by returning a wide range of unexpected results, often leading to practical applications that improve everyday life. Adding to SMOS’ list of talents, new findings show that what was considered noise in the mission’s data can actually be used to monitor solar activity and space weather, which can damage communication and navigation systems.

Spaceblower: A Rocket To Combat Space Debris
SpaceBlower is a light suborbital rocket designed to eject a cloud of particles into the path of large non-manoeuvrable space debris. Its goal is to avoid collisions likely to generate thousands more debris fragments and thus to keep satellites and their orbits safe. Space Blower is a preliminary project initiated and funded by CNES and its partner Bertin Technologies (now CT France). Christophe Bonnal, senior expert at CNES’s Launch Vehicles Directorate, outlines what this project is aiming to accomplish.
