SpaceX wants to launch roughly 30,000 Starlink satellites. NASA isn’t a fan of the plan. Find out more at 🚀 Engineering
Earlier this week, the space agency explained why in
At the moment, NASA — in cooperation with the Department of Defense — keeps tabs on 25,000 such objects, including the International Space Station, the Hubble Space Telescope, thousands of satellites pointed back toward Earth and out into space, and all kinds of debris leftover from decades of launches.“An increase [of the number of satellites] of this magnitude... brings additional risk of debris-generating collision events based on the number of objects alone,” NASA warns in the letter.
NASA's letter also notes that the satellites would sit at an altitude of 328-360 kilometers, just below the orbit of the International Space Station. When spacecraft visit the ISS to deliver supplies or bring new crewmembers, for example, they often spend time at that altitude to align with the ISS and prepare for docking, in what are called phasing maneuvers.
The thicket of satellites would also shorten the windows for safe launches, NASA said. Such launch windows are the moments — often fleeting — when everything from Earth's position in space to local weather conditions align. The agency specifically named the 2024 Europa Clipper mission as an example of the type of launch that could be put at risk.to launch that probe.
