The researchers observed unexpected, rapid “electron precipitation” from low-Earth orbit using the ELFIN mission, a pair of tiny satellites built and operated on the UCLA campus by undergraduate and graduate students guided by a small team of staff mentors. By combining the ELFIN data with more distant observations from NASA’s THEMIS spacecraft, the scientists determined Read more about Researchers discover source of super-fast electron rain[…]

On Feb. 3, SpaceX launched 49 small satellites into low earth orbit as a part of its Starlink program, an advanced satellite internet service that, as with many other products and services pioneered by American billionaire Elon Musk, is at least a little controversial. The satellites were carried into the atmosphere without a problem and Read more about Solar Storm Destroys 40 New SpaceX Starlink Satellites[…]

Chinese satellite was observed grabbing another satellite and pulling it out of its normal geosynchronous orbit and into a “super-graveyard drift orbit.” The maneuver raises questions about the potential applications of these types of satellites designed to maneuver close to other satellites for inspection or manipulation and adds to growing concerns about China’s space program Read more about A Chinese Satellite Just Grappled Another And Pulled It Out Of Orbit[…]

Just over 1,500 light-years away in the constellation of Hercules there’s a rugby ball-shaped exoplanet orbiting a star. It’s the first time astronomers have been able to detect such an unusual shape of an alien world. Most planets are more or less spherical due to gravitational forces that pull matter equally in from all sides, Read more about Massive rugby ball-shaped exoplanet spotted 1,500 ly away[…]

In a study published today in Nature, they describe an amorphous, 1,000-light-year-wide bubble ensconcing Earth that is responsible for those stars. Called the Local Bubble, the researchers believe it formed from a series of large explosions that blasted energy into space over the last 14 million years. Those explosions were supernovae—spectacular collapses of stars that Read more about Earth Is in a 1,000-Light-Year-Wide Bubble That Cooks Up Stars[…]

Heads up, future space travelers: No more commercial astronaut wings will be awarded from the Federal Aviation Administration after this year. The FAA said Friday it’s clipping its astronaut wings because too many people are now launching into space and it’s getting out of the astronaut designation business entirely. The news comes one day ahead Read more about FAA: No more commercial astronaut wings, too many launching. You still get to be on a list.[…]

Astrophysicists believe the heliosphere protects the planets within our solar system from powerful radiation emanating from supernovas, the final explosions of dying stars throughout the universe. They believe the heliosphere extends far beyond our solar system, but despite the massive buffer against cosmic radiation that the heliosphere provides Earth’s life-forms, no one really knows the Read more about Studying our solar system’s protective bubble[…]

The ranks of orbit-capable spaceflight companies just grew ever so slightly. TechCrunch reports Astra has reached orbit for the first time when its Rocket 3 booster launched shortly after 1AM Eastern today (November 20th). The startup put a mass simulator into a 310-mile-high orbit as part of a demonstration for the US Air Force’s Rapid Read more about Launch startup Astra reaches orbit for the first time[…]

[…] South Australian company Neumann Space has developed an “in-space electric propulsion system” that can be used in low Earth orbit to extend the missions of spacecraft, move satellites, or de-orbit them. Now Neumann is working on a plan with three other companies to turn space junk into fuel for that propulsion system. Japanese start-up Read more about ‘Gas station in space’: new plan to make rocket fuel from junk in Earth’s orbit[…]

In a test of its missile technology, Russia destroyed an old space satellite on Monday, littering Earth’s orbit with fragments and forcing astronauts on the International Space Station to temporarily take shelter. The cloud of debris was generated when Cosmos 1408, a 2,200-kg defunct signals intelligence satellite launched in 1982, was blown up by a Read more about ISS crew shelters from debris after Russia blows up old sat – US angry[…]

A U.S. space launch start-up has, for the first time, demonstrated a kinetic-based system that’s intended one day to put small spacecraft into orbit. The SpinLaunch concept, which feels ripped right from the classic age of science fiction, is based around a vacuum-sealed centrifuge that spins an unpowered projectile at several times the speed of Read more about Space Launch Start-Up Spinlaunch Just Used A Giant Centrifuge To Fling A Projectile Into The Upper Atmosphere[…]

this report from the New York Times about a “particularly unusual” star about 150 light-years away that’s orbited by three planets: What’s unusual is the inclinations of the outer two planets, HD 3167 c and d. Whereas in our solar system all the planets orbit in the same flat plane around the sun, these two Read more about Star System With Right-Angled Planets Surprises Astronomers[…]

The astronauts who will depart the International Space Station on Sunday will be stuck using diapers on the way home because of their capsule’s broken toilet. NASA astronaut Megan McArthur described the situation Friday as “suboptimal” but manageable. She and her three crewmates will spend 20 hours in their SpaceX capsule, from the time the Read more about No toilet for returning SpaceX crew, stuck using diapers – had just eaten chilli and tacos[…]

Chinese astronauts began Saturday their six-month mission on China’s first permanent space station, after successfully docking aboard their spacecraft. The astronauts, two men and a woman, were seen floating around the module before speaking via a live-streamed video. […] The space travelers’ Shenzhou-13 spacecraft was launched by a Long March-2F rocket at 12:23 a.m. Saturday Read more about New crew docks at China’s first permanent space station[…]

New Federal Aviation Administration (FAA) rules say astronaut hopefuls must be part of the flight crew and make contributions to space flight safety. That means Jeff Bezos and Sir Richard Branson may not yet be astronauts in the eyes of the US government. These are the first changes since the FAA wings programme began in Read more about FAA changes definition of “Astronaut” on day Bezos flies to space[…]

The rocket ship launched the 70-year-old and his crew from Spaceport America in the New Mexico desert. Tropical storms had delayed the launch before setting off at around 3.30pm. Branson – known as ‘Astronaut 001’ – soared into space in his blue spacesuit aboard Virgin Space Ship Unity, a 62ft rocket-powered space plane nestled between Read more about Richard Branson becomes first billionaire in space[…]

Virgin Orbit had a successful first commercial launch, meaning there’s now officially another small satellite launch provider in operation with a track record of delivering payloads to space. Virgin Orbit’s LauncherOne rocket took off from its carrier aircraft at around 11:45 AM EDT today, and the spacecraft had a successful series of engine fires and Read more about Virgin Orbit successfully launches its first commercial payloads to space[…]

China has launched three astronauts into orbit to begin occupation of the country’s new space station. The three men – Nie Haisheng, Liu Boming and Tang Hongbo – are to spend three months aboard the Tianhe module some 380km (236 miles) above the Earth.

The inevitable has occurred. A piece of space debris too small to be tracked has hit and damaged part of the International Space Station – namely, the Canadarm2 robotic arm. The instrument is still operational, but the object punctured the thermal blanket and damaged the boom beneath. It’s a sobering reminder that the low-Earth orbit’s Read more about Space Debris Has Hit And Damaged The International Space Station[…]
