A dead NASA space telescope and an old Air Force satellite avoided a crash on Wednesday, beating 'alarming' odds

Two dead satellites avoided a high-speed collision in space on Wednesday evening when their orbits crossed paths 560 miles above Pittsburgh, Pennsylvania. The larger object is an old space telescope called the Infrared Astronomical Satellite, or IRAS: a joint mission between NASA, the Netherlands, and the UK that ran out of fuel and died in November 1983. The other is a gravitational experiment called GGSE-4 that the US Air Force launched in May 1967. More
