The data collected on Jupiter and its moons were stored in the spacecraft's onboard tape recorder, and transmitted back to Earth during the long apoapsis portion of the probe's orbit using the low-gain antenna. At the same time, measurements were made of Jupiter's magnetosphere and transmitted back to Earth.
Galileo did both. One section of the spacecraft rotated at 3 revolutions per minute, keeping Galileo stable and holding six instruments that gathered data from many different directions, including the fields and particles instruments. Galileo was intentionally destroyed in Jupiter's atmosphere on September 21
Remote sensing instruments targeted Jupiter, its rings, and the Galilean satellites. C30 138 (86) 25 May 2001 The spacecraft observed the Asgard, Valhalla, and Bran craters in the closest flyby to date (in order to set up an Io encounter in August 2001). Camera problems were possibly due to continued radiation exposure that affected distant ...
Observations of variations in the brightness of Io as it rotated, made by Joel Stebbins in the 1920s, showed that Io's day was the same length as its orbital period around Jupiter, thus proving that one side always faced Jupiter just as the Moon's near-side always faces the Earth. [27]
The Europa Clipper spacecraft lifted off at 12:06 p.m. ET, and will travel 1.8 billion miles over more than five years to reach Jupiter. For decades, an icy moon of Jupiter has been considered one ...
The memo contains a speech for Nixon to read to the public should a "moon disaster" occur, such as astronauts Neil Armstrong and Buzz Aldrin becoming stranded, thus not being able to return to Earth.
Moon Failure: NASA's first attempt to land a spacecraft on the Moon. A series of malfunctions caused spacecraft to hurtle past the Moon. [6] April 23 US: Ranger 4: Atlas-Agena: Moon Partial failure: Was the first U.S. spacecraft to reach another celestial body. Failure in the onboard computer prevented it from carrying out its scientific ...
The spacecraft will reach Jupiter's moon Europa in 2030 and investigate if life could survive there. NASA launched Europa Clipper on Monday, Oct. 14. The spacecraft will reach Jupiter's moon ...
