Mission ends for Copernicus Sentinel-1B satellite
Wednesday, 03 August 2022 08:00
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.

Webb captures stellar gymnastics in the Cartwheel Galaxy
Tuesday, 02 August 2022 13:00
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

Remote surgery robot to be tested aboard International Space Station
Tuesday, 02 August 2022 12:00
A miniaturized robot invented by Nebraska Engineering Professor Shane Farritor may soon blast into space to test its skills.
NASA recently awarded the University of Nebraska-Lincoln $100,000 through the Established Program to Stimulate Competitive Research (EPSCoR) at the University of Nebraska Omaha to ready the surgical robot for a 2024 test mission aboard the International Space Station.
"NASA has been a long-term supporter of this research and, as a culmination of that effort, our robot will have a chance to fly on the International Space Station," Farritor said.
Farritor is co-founder of Virtual Incision, a startup company based on Nebraska Innovation Campus. For nearly 20 years, he and his colleagues have been developing the tiny surgical robot known as MIRA, short for "miniaturized in vivo robotic assistant.
Unveiling the distribution of dark matter around galaxies 12B years
Tuesday, 02 August 2022 11:32
A collaboration led by scientists at Nagoya University in Japan has investigated the nature of dark matter surrounding galaxies seen as they were 12 billion years ago, billions of years further back in time than ever before. Their findings, published in Physical Review Letters, offer the tantalizing possibility that the fundamental rules of cosmology may differ when examining the early history o Super-earth skimming habitable zone of red dwarf
Tuesday, 02 August 2022 11:32
A super-Earth planet has been found near the habitable zone of a red dwarf star only 37 light-years from the Earth. This is the first discovery by a new instrument on the Subaru Telescope and offers a chance to investigate the possibility of life on planets around nearby stars. With such a successful first result, we can expect that the Subaru Telescope will discover more, potentially even bette Northrop Grumman to lead Homeland Missile Defense Program for MDA

For a long time, our view of Ceres was fuzzy, said Scott King, a geoscientist in the Virginia Tech College of Science. A dwarf planet and the largest body found in the asteroid belt - the region between Jupiter and Mars speckled with hundreds of thousands of asteroids - Ceres had no distinguishable surface features in existing telescopic observations from Earth.

For this 3-sol weekend plan, I worked as the Tactical Uplink Lead. This morning we came in to discover that the drive had stopped early due to high slip on the steep terrain, and our parking place was not a safe spot to unstow and use the arm. So we quickly switched gears and loaded up the plan with lots of remote science.
