When the Galileo spacecraft's main antenna failed to unfurl on the way to Jupiter, engineers salvaged the mission by rewriting its software across deep space, compressing its data and squeezing a flagship science return through a low-gain antenna never me - Space Daily

Galileo, NASA’s flagship mission to Jupiter, launched in 1989, and on 11 April 1991 its large high-gain antenna failed to open as commanded. The mission was not abandoned. Over the following years a workaround was built, centred on new software both on the sp…

The fossilized backbones of what appeared to be woolly mammoths have turned out to come from an entirely different and unexpected animal.

Voyager 2 flew past Neptune in 1989 and detected faint hints of auroras it couldn't explain — because the magnetic field is tilted 47 degrees off the rotation axis and the auroras were glowing in entirely the wrong place - Space Daily

Voyager 2 flew past Neptune in 1989 and detected faint hints of auroras it couldn't explain — because the magnetic field is tilted 47 degrees off the rotation axis and the auroras were glowing in entirely the wrong place - Space Daily

The James Webb Space Telescope has captured direct evidence of auroras on Neptune, according to findings published in Nature Astronomy, with lead author Henrik Melin of Northumbria University. The observations were made using Webb’s Near-Infrared Spectrograph…

Two radio astronomers spent months trying to eliminate a faint hiss in their antenna, even scrubbing out pigeon droppings, before realising the noise they couldn’t get rid of was the afterglow of the early universe — the cosmic microwave background left behin - Space Daily

Two radio astronomers spent months trying to eliminate a faint hiss in their antenna, even scrubbing out pigeon droppings, before realising the noise they couldn’t get rid of was the afterglow of the early universe — the cosmic microwave background left behin - Space Daily

In 1964 and 1965, two radio astronomers at Bell Telephone Laboratories spent roughly a year trying to track down a faint, persistent noise in their antenna. They checked the electronics, they considered the sky, and at one point they cleaned out a pair of nes…
