NASA Launches Mission to Save Falling Telescope
NASA has launched an unmanned spacecraft to perform a maintenance mission on the Neil Gehrels Swift Observatory. The observatory, which studies gamma-ray bursts, was losing altitude due to solar activity and risked burning up in the atmosphere.
Why it matters
This mission demonstrates the capability to extend the life of critical space-based scientific assets through robotic intervention.

This threatened its ability to operate effectively and posed a risk of reentry into Earth's atmosphere, where it would burn up. </p><div class="mb-0 rounded-md bg-gray-100 p-3 md:p-5" id="related-video">
