Colleagues at the Jet Propulsion Laboratory said Claudia Alexander was particularly keen on engaging the public in space science. In her spare time, she wrote two books on science for children. She was She was the last project manager of Galileo, one of the most successful missions for exploring the distant reaches of the solar system. In particular, she spurred the creation of a Facebook group where members of the amateur community post comments on their sightings and interact with her and other scientists. Yanamandra-Fisher, a senior research scientist with the Space Science Institute who coordinated the outreach.

Shoemaker-Levy 9: Comet's Impact Left Its Mark on Jupiter | Space
The Galileo Probe was an atmospheric-entry probe carried by the main Galileo spacecraft to Jupiter , where it directly entered a hot spot and returned data from the planet. Inside the probe's heat shield , the scientific instruments were protected from extreme heat and pressure during its high-speed journey into the Jovian atmosphere, entering at The probe was released from the main spacecraft in July , five months before reaching Jupiter, and entered Jupiter's atmosphere with no braking beforehand. The probe was slowed from its arrival speed of about 47 kilometers per second to subsonic speed in less than two minutes. Each of 2 L-band transmitters operated at bytes per second and sent nearly identical streams of scientific data to the orbiter. All the probe's electronics were powered by lithium sulfur dioxide LiSO 2 batteries that provided a nominal power output of about watts with an estimated capacity of about 21 ampere-hours on arrival at Jupiter. The probe included seven instruments for taking data on its plunge into Jupiter: .
Comet Shoemaker-Levy 9's Epic Crash with Jupiter in Pictures
Comet Shoemaker-Levy 9 experienced one of the most spectacular ends that humans ever witnessed. Several months after its discovery, pieces of the comet smashed into the planet Jupiter. The collision produced scars that were visible from Earth.
Galileo was an American unmanned spacecraft that studied the planet Jupiter and its moons , as well as several other Solar System bodies. Named after the Italian astronomer Galileo Galilei , it consisted of an orbiter and an entry probe. Galileo arrived at Jupiter on December 7, , after gravitational assist flybys of Venus and Earth , and became the first spacecraft to orbit Jupiter. It launched the first probe into Jupiter, directly measuring its atmosphere.
