NASA's Swift observatory reentered over Sumatra on November 4 after a $30 million rescue attempt failed
NASA's Neil Gehrels Swift Observatory reentered at 7:39 a.m. EST on November 4 near 3°N, 99°E over North Sumatra, nearly 22 years after launching on a Delta II. NASA paid Katalyst Space $30 million for a robotic tug to boost it, but the tug lost attitude control and the capture was cancelled August 19. NASA put the ground risk at about 1 in 2,100.
