Complex subsurface of Mars imaged by Chinese rover Zhurong
Wednesday, 15 February 2023 05:22
Ground-penetrating radar from China's Martian rover Zhurong reveals shallow impact craters and other geologic structures in the top five meters of the red planet's surface. The images of the Martian subsurface are presented in a paper published in Geology Thursday.
The Zhurong rover was sent to Mars as part of China's Tianwen-1 mission. Launched in July 2020, the rover landed on the surfac Phase II of China's deep space observation radar facility kicks off construction

The second phase of China's deep space observation radar facility, dubbed "China Compound Eye", started construction Tuesday in southwestern Chongqing, according to the Beijing Institute of Technology.
Covering an area of more than 300 mu (20 hectares), the new phase will see the construction of 25 high-resolution radars, each with a diameter of 30 meters, and is expected to be completed i CSIC completes the first network of robotic telescopes present on the five continents

"BOOTES is the result of almost twenty-five years of continuous effort, since we installed the first station in 1998 at INTA (Arenosillo, Huelva), the institution that initially supported the project. The complete deployment represents a scientific milestone since it is the first robotic network with a presence on all continents", according to Alberto J.

The roar and crackle of Artemis 1
Tuesday, 14 February 2023 15:00
When the Artemis 1 mission was launched by NASA's Space Launch System, SLS, in November, it became the world's most powerful rocket, exceeding the thrust of the previous record holder, Saturn, by 13%. With liftoff came a loud roar heard miles away.
In JASA Express Letters, researchers from Brigham Young University and Rollins College in Florida reported noise measurements during the launch at different locations around Kennedy Space Center.
The data collected can be used to validate existing noise prediction models, which are needed to protect equipment as well as the surrounding environment and community. These data will be useful as more powerful lift vehicles, including the SLS series, are developed.
"We hope these early results will help prevent the spread of possible misinformation, as happened with the Saturn 5," author Kent Gee said. "Numerous websites and discussion forums suggested sound levels that were far too high, with inaccurate reports of the Saturn 5's sound waves melting concrete and causing grass fires.
NASA's IMAP spacecraft completes mission critical design review, moves closer to 2025 launch
Tuesday, 14 February 2023 14:43
NASA's Interstellar Mapping and Acceleration Probe (IMAP) spacecraft has completed the Mission Critical Design Review and is on track to meet its scheduled 2025 launch. Southwest Research Institute (SwRI) is managing the payload office, providing the scientific instrument Compact Dual Ion Composition Experiment (CoDICE) and is participating on other instrument teams for the mission, which will study the interaction between the solar wind and the interstellar medium as well as the fundamental processes of particle acceleration in space.

FCC greenlights Amazon's Project Kuiper to deploy 3,236 satellites in LEO
Tuesday, 14 February 2023 10:39
The Federal Communications Commission's (FCC) International Bureau approved Amazon on February 8 to deploy and operate their 3,236 low-Earth orbit (LEO) satellites, called "Project Kuiper," for broadband service using Ka-band radio frequencies.
The approval comes after satisfying requirements for orbital-debris mitigation, collision risk, and coordination with other satellite systems, re-e Tracking ocean microplastics from space
Tuesday, 14 February 2023 10:39
New information about an emerging technique that could track microplastics from space has been uncovered by researchers at the University of Michigan. It turns out that satellites are best at spotting soapy or oily residue, and microplastics appear to tag along with that residue.
