Why did NASA destroy Galileo?
Galileo changed the way we look at our solar system. When the spacecraft plunged into Jupiter’s crushing atmosphere on Sept. 21, 2003, it was being deliberately destroyed to protect one of its own discoveries—a possible ocean beneath the icy crust of the moon Europa.
What happened to the Galileo spacecraft?
The Galileo spacecraft’s 14-year odyssey came to an end on Sunday, Sept. 21, when the spacecraft passed into Jupiter’s shadow then disintegrated in the planet’s dense atmosphere at 11:57 a.m. Pacific Daylight Time.
Did Galileo actually land on Jupiter?
Galileo was intentionally destroyed in Jupiter’s atmosphere on September 21, 2003. The next orbiter to be sent to Jupiter was Juno, which arrived on July 5, 2016….Galileo (spacecraft)

What happened to the Mariner 1?
The first attempt by the United States to send a spacecraft to Venus, Mariner 1 was destroyed by the range safety officer about 290 seconds after launch when it veered off course.
What happened to Galileo on Jupiter?
Launched on Oct. 18, 1989 aboard the shuttle Atlantis, Galileo began a mission to explore Jupiter and its moons. After nearly 14 years of observations, Galileo was deliberately destroyed to protect one of its own discoveries: a saltwater ocean underneath the ice on Europa, one of Jupiter’s moons.
What spacecraft was intentionally destroyed in 2003 so that it could not hit Europa?
What spacecraft was intentionally destroyed in 2003 so that it could not hit Europa? Of the Galilean moons, the one with striking grooved terrain and icy tectonic features as well as older craters is: Ganymede.
Why did NASA crash a spacecraft into the moon?
Several rocket stages utilized during the Apollo space program were deliberately crashed on the Moon to aid seismic research, and four of the ascent stages of Apollo Lunar Modules were deliberately crashed onto the Moon after they had fulfilled their primary mission.
Where is Mariner 2 now?
Contact with Mariner 2 was lost on January 2, 1963, and it is now in orbit around the Sun. This object is a full scale engineering prototype and was constructed from flight spares by engineers at the Jet Propulsion Laboratory in 1977.
Why did the Mariner 3 fail?
SATCAT no. Although the launch was initially successful, there was a separation issue and Mariner 3 stopped responding when its batteries ran out of power. It was the third of ten spacecraft within the Mariner program.
Can we land a probe on Jupiter?
A major problem in sending space probes to Jupiter is that the planet has no solid surface on which to land, as there is a smooth transition between the planet’s atmosphere and its fluid interior. Any probes descending into the atmosphere are eventually crushed by the immense pressures within Jupiter.
What is the purpose of a high gain antenna in space?
It serves as the primary means of communication to and from the orbiter.The high-gain antenna must be pointed accurately and is therefore steered using the gimbal mechanism . Two smaller antennas provide lower-rate communication during emergencies and special events.
Why didn’t Galileo’s High-gain antenna open after launch?
Galileo’s original mission plan called for the high-gain antenna to open shortly after launch. For the Venus-Earth-Earth Gravity-Assist (VEEGA) trajec-tory mission, however, the heat-sensitive high-gain antenna had to be left closed and stowed behind a large sun shade to protect it during the spacecraft’s passage through the inner solar system.
What is the frequency range of a high gain antenna?
High-Gain Antenna The HGA transmits data to Earth on two frequency channels (the downlink). One, at about 8.4 gigahertz (8,400 million cycles per second), is the X-band channel and contains science and engineering data. For comparison, the FM radio band is centered around 100 megahertz.
How was the antenna for the Space Shuttle sent to space?
The antenna was originally shipped to JPL in Pasadena, CA, by truck in its own special shipping container. In December 1985, the antenna, again in its own shipping container, was sent by truck to NASA’s Kennedy Space Center (KSC) in Florida to await launch.
