Briefings

NASA's Swift Observatory ended its science mission after orbiting less than 171 miles above Earth, where atmospheric drag prevented steady astronomical observations. The spacecraft conducted its final observation on October 20, 2026, and is expected to re-enter the atmosphere within the next few weeks. The mission launched on November 20, 2004, and has observed over 2,000 gamma-ray bursts and 1,400 supernova explosions, contributing to approximately 7,000 scientific papers. Swift delivered a two-year primary mission with over 10 times the productivity of its actual duration, leaving an archive of 12 terabytes of data equivalent to 600 high-definition movies.

Key points

• The Swift Observatory ended its science mission after orbiting less than 171 miles above Earth, where atmospheric drag prevented steady astronomical observations.
• The spacecraft conducted its final observation on October 20, 2026, and is expected to re-enter the atmosphere within the next few weeks.

Limitations

The evidence is limited to a single article from October 2026, with no additional background or context provided. The article does not specify the exact date of the final observation, only the expected re-entry timeframe. The evidence does not include data on the mission's total operational duration or specific scientific outcomes beyond the number of gamma-ray bursts and supernovae observed.
