A space probe is a robotic spacecraft that does not orbit Earth, but instead, explores further into outer space. Space probes have different sets of scientific instruments onboard. A space probe may approach the Moon; travel through interplanetary space; flyby, orbit, or land on other planetary bodies; or enter interstellar space. Space probes ...
The 3MV planetary probe (short for 3rd generation Mars-Venus) is a designation for a common design used by early Soviet unmanned probes to Mars and Venus. [1] It was an incremental improvement of earlier 2MV probes and was used for Zond 1 , Zond 2 and Zond 3 missions to Mars as well as several Venera probes.
Sunshield full-size test for the James Webb Space Telescope. In spacecraft design, a Sun shield restricts or reduces heat caused by sunlight hitting a spacecraft. [6] An example of use of a thermal shield is on the Infrared Space Observatory. [6] The ISO sunshield helped protect the cryostat from sunlight, and it was also covered with solar ...
Juno Radiation Vault (the box being lowered onto the partially constructed spacecraft) in the process of being installed on Juno, 2010 Juno Radiation Vault is shown attached, but with the top open and some of the electronics boxes inside the vault can be seen The cube shaped JRV can be seen in between the un-wrapped main dish and the larger hexagonal main spacecraft body.
This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
The space probes Voyager 1 and Voyager 2 employ this method, and have used up about three quarters [4] of their 100 kg of propellant as of July 2015. Another method for achieving three-axis stabilization is to use electrically powered reaction wheels , also called momentum wheels, which are mounted on three orthogonal axes aboard the spacecraft.
Ulysses (/ j uː ˈ l ɪ s iː z / yoo-LISS-eez, UK also / ˈ j uː l ɪ s iː z / YOO-liss-eez) was a robotic space probe whose primary mission was to orbit the Sun and study it at all latitudes. It was launched in 1990 and made three "fast latitude scans" of the Sun in 1994/1995, 2000/2001, and 2007/2008. In addition, the probe studied ...
Solar System space probes operational as of November 2024. This is a list of active space probes which have escaped Earth orbit. It includes lunar space probes, but does not include space probes orbiting at the Sun–Earth Lagrangian points (for these, see List of objects at Lagrangian points). A craft is deemed "active" if it is still able to ...
