Galileo was an American robotic space probe that studied the planet Jupiter and its moons, as well as the asteroids Gaspra and Ida. Named after the Italian astronomer Galileo Galilei, it consisted of an orbiter and an entry probe. It was delivered into Earth orbit on October 18, 1989, by Space Shuttle Atlantis, during STS-34.
The Galileo orbiter thus became the first artificial satellite of Jupiter. [165] [166] Most of its initial orbit was occupied transmitting the data from the probe back to Earth. When the orbiter reached its apojove on March 26, 1996, the main engine was fired again to increase the orbit from four times the radius of Jupiter to ten times. By ...
The orbiter was 56 kilometers (184,000 ft) high and travelling at Mach 15.6. Space Shuttle Discovery as it approaches the International Space Station during the STS-114 on 28 July 2005. The Space Shuttle thermal protection system (TPS) is the barrier that protected the Space Shuttle Orbiter during the extreme 1,650 °C (3,000 °F ) heat of ...
On 11 January 2024, ISRO successfully deployed a 6-meter magnetometer boom aboard the Aditya-L1 in the Halo orbit at the Lagrange Point L1. After the liftoff, the boom had been stowed for 132 days. The in-orbit deployment period that was measured was roughly 9 seconds, which is well within the 8–12 second prediction range.
The Parker Solar Probe (PSP; previously Solar Probe, Solar Probe Plus or Solar Probe+) [ 6 ] is a NASA space probe launched in 2018 with the mission of making observations of the outer corona of the Sun. It will approach to within 9.86 solar radii (6.9 million km or 4.3 million miles) [ 7 ][ 8 ] from the center of the Sun, and by 2025 will ...
The Solar Orbiter (SolO) [7] is a Sun-observing probe developed by the European Space Agency (ESA) with a National Aeronautics and Space Administration (NASA) contribution. Solar Orbiter, designed to obtain detailed measurements of the inner heliosphere and the nascent solar wind , will also perform close observations of the polar regions of ...
The Lunar Orbiter program was a series of five uncrewed lunar orbiter missions launched by the United States in 1966 and 1967. Intended to help select Apollo landing sites by mapping the Moon's surface, [1] they provided the first photographs from lunar orbit and photographed both the Moon and Earth. All five missions were successful, and 99 ...
A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft, and a variable-shaped pickup coil. When the coil nears metal, the control box signals its presence with a ...
