Mars Auroras and Meteor Showers: Highlights for 10 August 2026

NASA's MAVEN spacecraft has provided new insights into the auroras on Mars, revealing how solar winds interact with the planet's atmosphere to create these spectacular light shows. Unlike Earth, Mars lacks a global magnetic field, resulting in auroras that are more widespread and diffuse. This discovery enhances our understanding of Martian atmospheric dynamics and could inform future missions to the Red Planet.

Perseid Meteor Shower Peaks

The Perseid meteor shower, one of the most anticipated celestial events of the year, is set to peak this week. With clear skies, observers can expect to see up to 100 meteors per hour. The shower is best viewed after midnight, away from city lights. For those planning to catch the display, the Orbital Radar Pass Predictor can help identify the best viewing times based on your location.

Satellite Close Approaches

Several close approaches between satellites are being monitored, including a near miss between COSMOS 2581 and COSMOS 2583 with a minimum distance of approximately 0.93 km. These events highlight the growing congestion in low Earth orbit, which now hosts over 18,000 active satellites. The Debris Map on Orbital Radar provides real-time tracking of these objects, aiding in collision avoidance strategies.

What to Watch

This week promises several noteworthy events in the space calendar. A total solar eclipse will occur on 12 August 2026, visible across parts of the Arctic and Greenland. Additionally, Katalyst Space is making strides in regaining control of the Swift servicing spacecraft, which could have implications for future satellite servicing missions. Keep an eye on the Launch Schedule for updates on upcoming missions.
