In summary: Galileo! On September 21, 2003, the Galileo spacecraft ended its successful mission by plunging into Jupiter at over 100,000 miles per hour. The spacecraft, launched in 1989, completed 35 orbits of Jupiter instead of the planned 11 and achieved the majority of its science objectives while making numerous discoveries along the way. Some of its many successes include completing flybys and measurements of Earth, Venus, and two asteroids, withstanding more radiation than designed for, and finding evidence of liquid oceans on three of Jupiter's moons. It also released a probe into Jupiter's atmosphere and took over 10,000 images, among many other achievements. Despite facing technical problems, Galileo completed its final scientific mission in

SUMMARY TIMELINE
1977 – congressional approval of the mission
1989 – launch from the Space Shuttle Atlantis
1990 – flybys/gravity assists of/from Venus & Earth
1991 – flyby of the asteroid Gaspra in the asteroid belt
1992 – second Earth flyby/gravity assist
1993 – flyby of the asteroid Ida + Dactyl
1995 – achieved orbit around Jupiter
2002 – final scientific mission (flyby of the small moon Amalthea)
2003 - End of mission. Kept on sending data until the end.

SOME OF ITS MANY SUCCESSES
- - Completed 35 orbits of Jupiter instead of just the planned 11
- - En route to Jupiter, it completed successful flybys & measurements of the Earth, Venus, & 2 asteroids
- - At Jupiter ,it withstood much more radiation than it was designed to take
- - Achieved the majority of its science objectives and made a number of serendipitous discoveries along the way
- - First close-up images of an asteroid (Gaspra)
- - First discovery of a tiny moon in orbit around an asteroid (Ida & Dactyl)
- - Imaged the Shoemaker-Levy 9 impact (views of the planet's far side that would have otherwise remained unseen)
- - Found evidence that three of Jupiter’s moons (Callisto, Europa and Ganymede) have liquid oceans (which led to speculations that they could harbor ET life)
- - Galileo released a probe into Jupiter’s atmosphere which transmitted data about the planet's chemical composition, winds, clouds and natural radiation environment.
- - Well over 10,000 images taken
- - Helped chart the structure of Jupiter’s Gossamer Ring (yes, Jupiter has rings too!)
- - First flyby of the small moon Amalthea
- - Found ~300 volcanoes on the moon Io
- - Overcame several technical problems (main antenna malfunction, damages from Jupiter’s extreme radiation, etc.)

Bye bye
 

1. What is "We'll miss you, Galileo"?

"We'll miss you, Galileo" is a phrase commonly used to express sadness or nostalgia for the passing of the Italian scientist Galileo Galilei.

2. Who was Galileo Galilei?

Galileo Galilei (1564-1642) was an Italian astronomer, physicist, and mathematician known as the "father of observational astronomy" and the "father of modern physics". He made significant contributions to the scientific understanding of motion, astronomy, and the laws of gravity.

3. Why do we miss Galileo?

We miss Galileo for his contributions and advancements in the fields of science and mathematics. He revolutionized our understanding of the universe and paved the way for future scientific discoveries. His work and legacy continue to inspire and influence scientists and thinkers today.

4. What are some of Galileo's most famous discoveries?

Some of Galileo's most famous discoveries include the four largest moons of Jupiter (now known as the Galilean moons), the phases of Venus, and the law of falling bodies. He also made significant improvements to the telescope, allowing for more detailed observations of the night sky.

5. How did Galileo's work impact the scientific community?

Galileo's work had a profound impact on the scientific community, as he challenged and overturned many long-held beliefs and theories. His emphasis on observation and experimentation laid the foundation for the scientific method, which is still used today. He also faced persecution for his beliefs and paved the way for future scientific freedom and progress.
