NASA's Mars 2020 Perseverance rover mission is just 22 days from landing on the surface of Mars. The spacecraft has about 25.6 million miles (41.2M km) remaining in its 292.5-million-mile (470.8M km) journey and is currently closing that distance at 1.6 miles per second (2.5 kilometers per second).

In September, a team led by astronomers in the United Kingdom announced that they had detected the chemical phosphine in the thick clouds of Venus. The team's reported detection, based on observations by two Earth-based radio telescopes, surprised many Venus experts. Earth's atmosphere contains small amounts of phosphine, which may be produced by life. Phosphine on Venus generated buzz that the NASA spacewalk partially hooks up new science platform

Two NASA astronauts were unable to complete work during a spacewalk Wednesday on hooking up Europe's new Bartolomeo science platform outside the International Space Station.
Mike Hopkins and Victor Glover spent 6 hours, 56 minutes on the spacewalk. The assignment was the first spacewalk for Glover, the first Black astronaut to live and work aboard the space station.

At NASA's Michoud Assembly Facility in New Orleans, technicians from Orion prime contractor Lockheed Martin have welded together three cone-shaped panels on Orion's crew module for the Artemis III mission that will land the first woman and next man on the Moon.
The crew module's primary structure, the pressure vessel, is comprised of seven machined aluminum alloy pieces that are welded tog NASA's Artemis Base Camp on the Moon will need light, water, elevation

American astronauts in 2024 will take their first steps near the Moon's South Pole: the land of extreme light, extreme darkness, and frozen water that could fuel NASA's Artemis lunar base and the agency's leap into deep space.
Scientists and engineers are helping NASA determine the precise location of the Artemis Base Camp concept. Among the many things NASA must take into account in choos How heavy is dark matter

Scientists have calculated the mass range for Dark Matter - and it's tighter than the science world thought.
Their findings - due to be published in Physics Letters B in March - radically narrow the range of potential masses for Dark Matter particles, and help to focus the search for future Dark Matter-hunters.

NASA is one step closer to understanding the solar power challenges and opportunities on the Moon's surface after completing the build and readiness review of the Photovoltaic Investigation on the Lunar Surface, or PILS, experiment. The agency overcame multiple engineering challenges to get the experiment ready for integration with a commercial lander for a ride to the Moon as part of NASA's Com Satellite data reveals bonds between emissions, pollution and economy

Burning fossil fuels has long powered world economies while contributing to air pollution and the buildup of greenhouse gases. A new analysis of nearly two decades of satellite data shows that economic development, fossil-fuel combustion and air quality are closely linked on the continental and national scales, but can be decoupled at the national level, according to Penn State scientists.

WASHINGTON — Rep. Jim Cooper (D-Tenn.), a leading proponent of establishing the U.S. Space Force, said he wants the Biden administration to put pressure on the service to clean up its procurement act.
Cooper chairs the House Armed Services Committee’s strategic forces subcommittee that wrote language in 2017 to establish a Space Corps, which ultimately became the Space Force.
Purported phosphine on Venus more likely to be ordinary sulfur dioxide, new study shows

In September, a team led by astronomers in the United Kingdom announced that they had detected the chemical phosphine in the thick clouds of Venus. The team's reported detection, based on observations by two Earth-based radio telescopes, surprised many Venus experts. Earth's atmosphere contains small amounts of phosphine, which may be produced by life. Phosphine on Venus generated buzz that the planet, often succinctly touted as a "hellscape," could somehow harbor life within its acidic clouds.
Since that initial claim, other science teams have cast doubt on the reliability of the phosphine detection. Now, a team led by researchers at the University of Washington has used a robust model of the conditions within the atmosphere of Venus to revisit and comprehensively reinterpret the radio telescope observations underlying the initial phosphine claim.
