Space Stories: NASA Aircraft Assist with Texas Flood, Chinese Satellites Do Something New, and Venus May be Probed by the UK

Here are some recent space-related stories of interest.

—NASA “NASA Aircraft, Sensor Technology, Aid in Texas Flood Recovery Efforts“

In response to recent flooding near Kerrville, Texas, NASA deployed two aircraft to assist state and local authorities in ongoing recovery operations. The aircraft are part of the response from NASA’s Disasters Response Coordination System, which is activated to support emergency response for the flooding and is working closely with the Texas Division of Emergency Management, the Federal Emergency Management Agency (FEMA), and the humanitarian groups Save the Children and GiveDirectly.

—Newsweek: “China Appears to Pull Off Satellite Feat That NASA Has Never Achieved“

Two remote-controlled Chinese satellites appear to have docked in high orbit to allow refueling and servicing for the first time. The achievement, which has yet to be matched by the U.S, involved autonomous spacecraft Shijian-21 and Shijian-25, completing the task in geostationary orbit earlier this month. Geostationary orbits occur at 22,236 miles above the surface, and are typically used for communications satellites so that they can move with the rotation of the Earth. However, the high orbit and need for satellites to maintain speeds with the Earth’s rotation makes docking extremely difficult.

—Royal Astronomical Society: “Life on Venus? UK Probe Could Reveal the Answer“

The answer to whether tiny bacterial lifeforms really do exist in the clouds of Venus could be revealed once-and-for-all by a UK-backed mission. Over the past five years researchers have detected the presence of two potential biomarkers – the gases phosphine and ammonia – which on Earth can only be produced by biological activity and industrial processes. Their existence in the Venusian clouds cannot easily be explained by known atmospheric or geological phenomena, so Cardiff University’s Professor Jane Greaves and her team are plotting a way to get to the bottom of it. Revealing a new mission concept at the Royal Astronomical Society’s National Astronomy Meeting 2025 in Durham, they plan to search and map phosphine, ammonia, and other gases rich in hydrogen that shouldn’t be on Venus.
