Doomed NASA Spacecraft Sends Final Cosmic Images Before Earth Re-entry

NASA's Neil Gehrels Swift Observatory, a spacecraft that has been operational for 21 years, is set to re-enter Earth's atmosphere later this year, approximately in November. Before its planned demise, the observatory has transmitted a collection of newly released cosmic images.

Launched in 2004, Swift was designed to detect and monitor gamma-ray bursts. However, increased solar activity has caused its low-Earth orbit to decay rapidly, making its return to Earth inevitable. A mission undertaken over the summer to boost Swift's orbit and extend its operational life was unsuccessful.

The observatory, weighing 1,470 kg and measuring 5.6 meters in height, is expected to largely break up and burn upon atmospheric entry. NASA has not yet confirmed whether any debris will reach the Earth's surface.

The latest images released by NASA showcase celestial objects observed through the combined efforts of Swift and the Chandra X-ray Observatory. These include the Small Magellanic Cloud (SMC), a neighboring galaxy to the Milky Way situated approximately 200,000 light-years away. Another featured image is of NGC 1097, a spiral galaxy located about 48 million light-years from Earth, known to harbor a supermassive black hole roughly 140 million times the mass of the Sun.

Also included is an image of the spiral galaxy NGC 4151, which is noted for having an actively growing supermassive black hole at its core. The observatory's mission has contributed to a greater understanding of cosmic mysteries throughout its extended service.

The failed attempt to save Swift involved Katalyst Space's LINK robotic servicing spacecraft. An ongoing attitude-control issue with Swift prevented the LINK vehicle from successfully capturing the observatory, leading to the mission's failure. The LINK spacecraft was prepared for the rescue mission inside a Northrop Grumman Pegasus XL rocket at NASA's Wallops Flight Facility in Virginia.
