From their humble beginnings as experimental entities, smallsats have come a long way to become an independent type of satellites that is now indispensable to space operations. Recent developments in miniaturization, in-space propulsion, onboard processing and control, and communication systems have ...
Orbit-to-orbit spacecraft never land on any planet, moon, or asteroid. Therefore they are free to use efficient propulsion systems with a thrust-to-weight ratio below 1.0, such as ion drives or VASIMR. They require no landing gear or parachutes. If there ain't no landing gear, it is ...

EMIT images consist of 285 bands with wavelength ranging from 381-2,492 nanometers (nm). To learn more about EMIT and applications, see Jet Propulsion Laboratory. EMIT products are stored as NetCDF files. To work with EMIT Level 1 and Level 2 products, create a mosaic dataset using the ...
Rocket Scientist:Rocket scientists design and develop the propulsion systems used in rockets and spacecraft. They work on improving efficiency and safety in launching and navigating through space. Space Law and Policy Expert:With the increasing commercialization of space, there is a growing need for ...
Spaceflight, flight beyond Earth’s atmosphere. This article deals with the basic concepts associated with the launch and return of unmanned and manned spacecraft and their travel, navigation, and rendezvous and docking in space. For the development of s
Launch vehicle, a rocket-powered vehicle used to transport a spacecraft beyond Earth’s atmosphere, either into orbit around Earth or to some other destination in outer space. Practical launch vehicles have been used to send crewed spacecraft, uncrewed s
