On 23 December 2021, Copernicus Sentinel-1B experienced an anomaly related to the instrument electronics power supply provided by the satellite platform, leaving it unable to deliver radar data. Since then spacecraft operators and engineers have been working tirelessly to rectify the issue. Unfortunately, despite all concerted efforts, ESA and the European Commission announce that it is the end of the mission for Sentinel-1B. Copernicus Sentinel-1A remains fully operational and plans are in force to launch Sentinel-1C as soon as possible.

JWST Turns Its Gaze on the Cartwheel Galaxy
The Cartwheel Galaxy, also known as ESO 350-40, is one disturbed-looking piece of cosmic real estate. To look at it now, especially in the latest JWST view, you’d never know it used to be a gorgeous spiral galaxy. That was before it got involved in a head-on collision with a companion. The encounter happened somewhere around 200-300 million years ago. Essentially, the smaller galaxy “bulls-eyed” the Cartwheel, right through its heart. A shock wave swept through the system, changing everything. The aftermath is what we see in this latest image from JWST.

New Russian space chief clarifies comments about International Space Station departure
Russia won't rush its exit from the International Space Station, but the nation is planning ahead for when that day arrives.
Perseverance Mars rover snags 11th rock sample
NASA's Perseverance Mars rover bagged its 11th sample on Mars, targeting a sedimentary rock that may preserve "biosignatures" of ancient life on the Red Planet.
Smithsonian to debut reimagined Air and Space Museum galleries on Oct. 14
The countdown is now on for the launch of the first reimagined galleries in the National Air and Space Museum. The Smithsonian announced that it will reopen half of the flagship building on Oct. 14.
Stunning James Webb Space Telescope image shows stars forming in strange wheel-shaped galaxy
The James Webb Space Telescope peered through dust and gas to reveal star formation in a rare wheel-shaped galaxy that formed in a long-ago galactic crash.
NASA looks to private outposts to build on International Space Station's legacy
The ISS can't fly forever, and NASA officials envision a diverse market of commercial space stations taking its place as demand for access to low Earth orbit continues to increase.
Russians reportedly building a satellite-blinding laser — an expert explains the technology
Russia is building a new ground-based laser facility for interfering with satellites orbiting overhead, according to a recent report. Here's what that means.
Space philosopher Frank White on 'The Overview Effect' and humanity's connection with Earth
Frank White's "overview effect" has increasingly become iconic for explaining a very human condition attached to the space travel experience.
Virgin Galactic plans new astronaut training facility near Spaceport America
Virgin Galactic has acquired land for a new astronaut campus and training facility in New Mexico close to Spaceport America.
The Record for the Farthest Galaxy just got Broken Again, now just 250 million years after the Big Bang
In a recent study submitted to MNRAS, a collaborative research team has utilized the first set of data from the James Webb Space Telescope (JWST) discovering a galaxy candidate, CEERS-93316, that formed approximately 250 million years after the Bing Bang, which also set a new redshift record of z = 16.7. This finding is extremely intriguing as it demonstrates the power of JWST, which only started sending back its first set of data a few weeks ago. CEERS stands for Cosmic Evolution Early Release Science Survey, and was specifically created for imaging with JWST.
Curiosity rover: The ultimate guide
NASA's Curiosity rover is still exploring the Martian surface and looking for signs of life on Mars. We explore the rover in more detail here.

James Webb Space Telescope glimpses Earendel, the most distant star known in the universe
The James Webb Space Telescope has caught a glimpse of the most distant star known in the universe, which had been announced by scientists using Webb's predecessor Hubble only a few months ago.
Russia's withdrawal from the International Space Station could mean the early demise of the orbital lab — and sever another link with the West
Russia's announcement, while not a breach of any agreement or an immediate threat to the station's daily operation, does mark the culmination of months of political tensions involving the ISS.
Summer Insomnia
Long, hot days mean sleepless nights for stargazers, but it's worth it for the magic that happens under a dark, cool sky.
Is the James Webb Space Telescope finding the furthest, oldest, youngest or first galaxies? An astronomer explains.
We’ve now seen the first data from the James Webb Space Telescope. It has observed the atmospheres of distant planets, groups of nearby galaxies, galaxy light bent by unseen dark matter, and clouds of gas and dust in stellar nurseries.
Webb captures stellar gymnastics in the Cartwheel Galaxy
The Cartwheel Galaxy, a rare ring galaxy once shrouded in dust and mystery, has been unveiled by the imaging capabilities of the NASA/ESA/CSA James Webb Space Telescope. The galaxy, which formed as a result of a collision between a large spiral galaxy and another smaller galaxy, not only retained a lot of its spiral character, but has also experienced massive changes throughout its structure. Webb’s high-precision instruments resolved individual stars and star-forming regions within the Cartwheel, and revealed the behaviour of the black hole within its galactic centre. These new details provide a renewed understanding of a galaxy in the midst of a slow transformation.
