​The Fall of NASA's Swift Observatory


​The Fall of NASA's Swift Observatory

​The Neil Gehrels Swift Observatory, a space telescope that has studied cosmic gamma-ray bursts and explosions since 2004, is running out of time. Due to its rapidly decaying orbit, the spacecraft is falling back to Earth and is expected to reenter the atmosphere and burn up entirely later this year (likely in October).

  The Failed Rescue Mission
​To save the telescope, NASA and Katalyst Space launched an experimental commercial robotic repair vehicle named LINK on July 3, 2026. LINK was designed to rendezvous with Swift and boost it into a higher orbit.
​Unfortunately, the rescue mission failed:
​About three weeks into the flight, two of LINK's three reaction wheels malfunctioned.
​The failure caused an uncontrolled spin and intermittent communication issues.
​Katalyst and NASA announced that LINK cannot capture or boost Swift.
​Despite the mission's primary failure, the teams will continue proximity operations with Swift to gather valuable data for future satellite-servicing missions.

Tracking Swift and LINK:
​Amateur astronomers, such as the Sociedad de Astronomía del Caribe in Puerto Rico, have successfully captured video of both spacecraft passing near bright stars like Antares.
​Observers hoping to spot the decaying Swift spacecraft in the night sky can track it using platforms like HeavensAbove.com
​Set Location: Input your exact GPS coordinates or city.
​Search Satellites: Look up "Swift" (NORAD ID 28485) or "LINK".
​Generate Predictions: Check the 10-day pass tables for high elevations and favorable brightness (Swift typically reaches a visible magnitude of +1.5 to +2.0, making it visible to the naked eye under dark skies).
​Use Star Charts: View interactive trajectory maps to locate the spacecraft against background constellations.
​Swift's Scientific Legacy
​Swift has relied on three key instruments to monitor the universe:
​Burst Alert Telescope (BAT): A wide-field gamma-ray detector that continuously watches for sudden high-energy flashes.
​X-Ray Telescope (XRT): Measures and tracks the fading X-ray afterglows of detected bursts.
Meet the space-based Swift Observatory. Its orbit is decaying; it is falling back to Earth. NASA planned to save it and boost it to a higher orbit, with a rescue mission called LINK. The intervention failed and Swift will plunge back to Earth by the fall of 2026. Image via NASA

​Ultraviolet/Optical Telescope (UVOT): Provides precise positions, colors, and detailed data in ultraviolet and visible light to help determine distances and host galaxies.
​Would you like a shorter summary focused specifically on the spacecraft reentry timeline, or more details on how to track it?

ON AUGUST 5, SOMETHING EXTRAORDINARY WILL HAPPEN ON THE MOON.

ON AUGUST 5, SOMETHING EXTRAORDINARY WILL HAPPEN ON THE MOON. A used Falcon 9 upper stage is expected to slam into the lunar surface near Einstein Crater after years drifting through space. Astronomers around the world are already preparing to observe the impact and the plume of material that could be blasted high above the Moon's surface. And this may become one of the most closely watched artificial impacts in lunar history. Think about that for a moment. A machine built by human hands, launched from Earth, traveling silently through the darkness of space, will end its journey by crashing into another world at thousands of kilometers per hour. The impact is expected to create a fresh crater and expose material hidden beneath the Moon's dusty surface. Scientists hope the collision could reveal layers that have remained untouched for millions of years, offering a rare opportunity to study what lies below. Even more fascinating, future lunar orbiters may be able to p...

NASA's Europa Clipper Will Reach Europa in 2030 to Investigate an Underground Ocean Larger Than All Of Earth's Oceans and Determine Whether it Could Habour Life...   Europa Clipper Was Launched on October 14, 2024, the spacecraft is currently journeying through the inner Solar System. It utilized a Mars gravity assist in March 2025 and is scheduled for an Earth gravity assist to sling-shot it toward Jupiter.    Europa Clipper is the largest interplanetary spacecraft ever constructed by NASA, featuring massive solar arrays spanning 30.5 meters to capture adequate sunlight at Jupiter's distance.   Jupiter features a severe radiation belt that would quickly damage electronics, the spacecraft will orbit Jupiter itself rather than parking permanently around Europa.   Starting 2031, the probe will execute 49 close passes over Europa’s icy surface to gather comprehensive radar, thermal, and compositional data.

Astronomers are Against The Startup's Idea to Sell Sunlight Using Gaint Mirrors in Space

Astronomers are Against The Startup's Idea to Sell Sunlight Using Gaint Mirrors in Space  Why Astronomers Are Up in Arms Over Space Startup’s Plan to Sell Sunlight The concept of manipulating planetary light from orbit sounds like something straight out of science fiction. For over a century, thinkers have toyed with the idea of positioning giant mirrors in space to redirect sunlight onto Earth after dark. Today, a California-based startup called Reflect Orbital is turning that theoretical concept into reality, pitching a service designed to "sell sunlight after dark". However, this ambitious technological push has triggered fierce opposition from the global scientific community. Astronomers, dark-sky advocates, and environmental researchers are sounding the alarm, warning that the project threatens to permanently alter the night sky, disrupt natural ecosystems, and deal a crippling blow to astronomical research.     What is Reflect Orbital Trying to Do? Found...
