Unearthing the Mysteries of Space Collisions: What’s Happening with Our Satellites?
The increasing number of satellites orbiting Earth is raising concerns about space debris and potential collisions. This week, satellite company NanoAvionics revealed that one of their MP42 microsatellites survived an unexpected impact. Let’s delve into the details of this event and what it means for satellite operations in low Earth orbit.
The Satellite’s Selfie Reveals Damage
NanoAvionics recently discovered a hole in one of the solar panels of their MP42 satellite. The damage was caught on camera in an October 2023 selfie taken by the satellite’s onboard camera. The hole, measuring 0.2 inches (6 millimeters), is a result of an unknown object colliding with the satellite sometime over the past year and a half.
The exact identity of the impactor remains uncertain, but NanoAvionics has理论 alternative possibilities. They cited a piece of space debris or a micrometeoroid as the most likely culprits. In an official statement, they joked about the possibility of an "alien satellite-pecker," suggesting the serious implications of space debris.
Despite the abrasion to its solar panel, MP42 continues to operate normally. Telemetry data indicates that the impact didn’t affect the satellite’s ability to generate power, which is, unfortunately, making it more difficult to determine the exact timeline of the collision.
The Growing Concern of Orbital Debris
Space is getting increasingly crowded. In fact, there are more than 27,000 tracked pieces of orbital debris, with many more undetected. Furthermore, the incident with the MP42 satellite reminded us of the latest space collision. Earlier this month, a communications satellite broke apart in orbit, spreading uncontrolled debris that grew to nearly 500 pieces.
The International Space Station has needed to conduct 32 collision avoidance maneuvers between 1999 and 2022 to dodge debris, underscoring the growing risk of space collisions. As more satellites launch, this problem is likely to worsen, highlighting the pressing need for better space debris prevention and mitigation strategies.

Keeping an Eye on Space Debris
Tracking thousands of pieces of space debris is a task taken up by the U.S. Department of Defense’s Space Surveillance Network. This network continuously monitors orbital bodies to identify any potential collisions.
NanoAvionics’ Commitment to satellite Sustainability
To mitigate the long-term impact of debris, NanoAvionics equips its satellites with controlled deorbiting systems. These propulsion systems ensure that satellites can safely de-orbit at the end of their lifespans, reducing orbital pollution.
Calls for Better Space Operations
Satellite collisions like the one experienced by MP42 underscore the urgent need for proactive measures to handle space debris. Industries should commit to responsible space operations and work towards reducing orbital debris to increase safety and longevity in space.
As space becomes more accessible, let’s take a closer look at who is leading the way in satellite propulsion technologies and debris mitigation. Companies adopting responsible practices are not only ensuring sustainable space operations but also paving the path for a cleaner orbit, reducing the risk of future collisions.
