Satellites and drones can save the pollinating insects

  • One response
Satellites and drones can provide vital information that can contribute to the protection of nature's pollinators. New research is exploring new ways to utilize these technologies to track the availability of flowers, where this research may be combined with behavioral studies to see the world through the eyes of insects
Clusters of satellites, such as the BlueWalker 3 prototype, are causing concern among astronomers due to possible interference with night sky observations and radio astronomy. Balancing the global needs for communication and maintaining astronomical research is critical. Credit: AST SpaceMobile

The BlueWalker 3 satellite whose antenna area is 64 square meters has become one of the brightest objects in the night sky, the fear is that when there are a hundred satellites in this constellation and hundreds in other constellations it will be impossible to observe the sky in the optical field and there will also be interference to the radio field

Astroscale: Spacecraft and satellite manufacturers should commit to a significant reduction in the number of abandoned objects in space

  • One response
Satellite manufacturers, spacecraft operators, and the like, should receive specific and verifiable commitments to limit the number of objects in space in practice, and not just the predicted number of abandoned objects they produce during their activity, and to include in the planning the waste disposal at the end of the vessel's life

If the Russian government is able to build the laser, it will be able to protect a large part of the country from observation by satellites with optical sensors. The technology also paves the way for the more threatening possibility of laser weapons that can permanently disable satellites

The European Space Agency's station in Tenerife is a technology testing facility and an essential first step in making waste reduction widely accessible to all players in space who have an impact on the future of our space environment * It will be able to track satellites even in the sky today
