Space probes operational as of November 2023. 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 transmit ...
NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather ...
The Chandra X-ray Observatory (CXO), previously known as the Advanced X-ray Astrophysics Facility (AXAF), is a Flagship-class space telescope launched aboard the Space Shuttle Columbia during STS-93 by NASA on July 23, 1999. Chandra was sensitive to X-ray sources 100 times fainter than any previous X-ray telescope, enabled by the high angular ...
This timeline of artificial satellites and space probes includes uncrewed spacecraft including technology demonstrators, observatories, lunar probes, and interplanetary probes. First satellites from each country are included. Not included are most Earth science satellites, commercial satellites or crewed missions.

Flyby: The probe flies by an astronomical body, but does not orbit it. Orbiter: Part of a probe that orbits an astronomical body. Lander: Part of a probe that descend to the surface of an astronomical body. Rover: Part of a probe that acts as a vehicle to move on the solid-surface of an astronomical body.
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 satellites orbit in a circular low Earth orbit at about 500 km (310 mi) altitude [326] in a high-inclination orbit for a planned six to twelve-month duration. The satellites communicate with three testing ground stations in Washington State and California for short-term experiments of less than ten minutes duration, roughly daily. [321] [327]
