In late 1971, after NASA approved the idea of sending a message aboard Pioneer 10, Carl Sagan was given just three weeks to prepare it. Working with astronomer Frank Drake and artist Linda Salzman Sagan, he helped create a six-by-nine-inch gold-anodized alumi…

Michael Collins, dubbed by the press "the loneliest man in history" while orbiting the far side of the Moon for roughly forty-seven minutes at a time, gently corrected the description — he said he felt isolated, but never lonely - Space Daily

As the command module Columbia slipped behind the Moon on the afternoon of July 20, 1969 and lost radio contact with the world, Mission Control said over the open air: “Not since Adam has any human known such solitude as Mike Collins is experiencing during th…

In 1995, NASA’s Galileo spacecraft sent a probe into Jupiter’s atmosphere that kept transmitting for just 58 minutes as it fell, returning the first direct readings from inside the giant planet before rising heat and pressure silenced it for good - Space Daily

On 7 December 1995, a small probe released by NASA’s Galileo spacecraft entered the atmosphere of Jupiter and transmitted data as it fell. It kept transmitting for about 58 minutes before rising heat and pressure ended the signal. In that time it returned the…

When a Soviet rover went silent on the Moon in 1971, scientists assumed it was gone for good — but nearly forty years later, the reflector strapped to its back answered a laser pulse from Earth as if no time had passed at all - Space Daily
