Webb finds water, and a new mystery, in rare main-belt comet
Monday, 15 May 2023 14:00The NASA/ESA/CSA James Webb Space Telescope has enabled another long-sought scientific breakthrough, this time for Solar System scientists studying the origins of the water that has made life on Earth possible. Using Webb’s NIRSpec (Near-Infrared Spectrograph) instrument, astronomers have confirmed gas – specifically water vapour – around a comet in the main asteroid belt for the first time, proving that water from the primordial Solar System can be preserved as ice in that region. However, the successful detection of water comes with a new puzzle: unlike other comets, Comet 238P/Read had no detectable carbon dioxide.

For 191st time, SpaceX booster successfully returns after launch
Monday, 15 May 2023 04:55SpaceX on Sunday morning successfully deployed another batch of Starlink satellites into space and successfully landed its first-stage booster. The Falcon 9 rocket with the satellites lifted off from the Cape Canaveral Space Force Station just after midnight, illuminating the night skies over Florida's central east coast. The first-stage booster then returned to Earth and landed
Bacteria survive on radioactive elements
Monday, 15 May 2023 04:55Bacteria that feed on methanol are able to grow on certain rare earth elements as well as their radioactive relatives. These findings suggest a possible role for such bacteria in the decontamination of areas where actinides are spilled, or in the separation of lanthanides and actinides for analytical or preparative purposes, according to a study published in the journal Angewandte Chemie.

Sitting still but not idling at Ubajara: Sols 3827-3829
Monday, 15 May 2023 00:08Drilling campaigns force us to sit and stop, whilst the "Ubajara" drill sample is analyzed. This takes a week or two, depending on the types of analysis that CheMin and SAM chose to do. This might sound like we are sitting quietly, just waiting but drill campaigns are furiously busy and "power hungry." CheMin planned the first part of their analysis on Wednesday, and today, they added a se
NASA calls end to Lunar Flashlight after some tech successes
Monday, 15 May 2023 00:08While the CubeSat couldn't reach the lunar South Pole to help seek ice, it fulfilled several technology goals that will empower future missions for the benefit of humanity. NASA's Lunar Flashlight launched on Dec. 11, 2022, to demonstrate several new technologies, with an ultimate goal to seek out surface ice in the permanently shadowed craters of the Moon's South Pole. Since then, the bri
Tidal shocks can light up the remains of a star being pulled apart by a black hole
Monday, 15 May 2023 00:08The Universe is a violent place where even the life of a star can be cut short. This occurs when a star finds itself in a "bad" neighbourhood, specifically near a supermassive black hole. These black holes weigh millions or even billions of times the mass of the Sun and typically reside in the centres of quiet galaxies. As a star moves closer to the black hole, it experiences the ever-incr
"Tianzhou Express" is online again, with five highlights
Monday, 15 May 2023 00:08On May 10, 2023, the Tianzhou-6 cargo spacecraft was successfully launched aboard the Long March 7 Yaoqi carrier rocket from the Wenchang Space Launch Site in China at 21:22 Beijing time. Roughly ten minutes after the launch, the spacecraft separated from the rocket and entered its predetermined orbit, with the solar panels operating smoothly, marking the launch as a complete success. The follow

Juice's RIME antenna breaks free
Saturday, 13 May 2023 22:11Over three weeks since the initiation of the deployment process for Juice's Radar for Icy Moons Exploration (RIME) antenna, the 16-meter-long boom has finally been liberated from its mounting bracket. During the first attempt at stretching out the compacted antenna, only the initial segments of each half were released. The flight controllers theorized that a minuscule stuck pin prevented t
