Small satellites, with their short development time and low cost, greatly increase the accessibility of space technology to businesses and researchers.
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 ...
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 ...
Sentinel-2 spacecraft has a Multi-Spectral Instrument (MSI) that collects data in spectral bands spanning from the visible and the near infrared to the shortwave infrared spectra at three different resolutions: 4 bands at 10 meters 6 bands at 20 meters 3 bands at 60 meters Sentinel-2 MSI da...
Mars-orbiting spacecraft have detected water vapor in the Martian atmosphere, particularly in white clouds and fog. Temperature measurements made by the Viking Orbiter missions in the 1970s revealed that the north pole residual cap, which remains year-round, even at the height of Martian summer,...
VOYAGER 2 SPACECRAFTDATA TRANSMISSIONSPACECRAFT COMMUNICATIONSTATISTICAL ANALYSISVoyager radio navigation made use of a differenced rage data type for both Saturn encounters because of the low declination singularity of Doppler data. Nearly simultaneous two-way range from two-station baselines was explicitly...

PDE produces a higher specific thrust than comparable ramjet engines at speeds suitable for use as part of a multi-stage propulsion system. It can also be used to reduce the cost and complexity of launching spacecraft. But there are several drawbacks that need to be overcome in PDE. PDE is...
