Instrument Landing System

The surface area of Saturn's moon Mimas is slightly less than the land area of Spain and is composed of water ice with only a small amount of rock. Yet Saturn's resonances with Mimas, and Mimas' resonances with other orbiting satellites are instrumental in the formation of Saturn's rings.


The nuclear-powered mobile science laboratory Curiosity is to rove across the surface of Mars for years, searching for the conditions that may have once made Mars an abode of life.


Surface Of Venus

Surface Of Venus- Oh that strange toxic yellow sky! The surface conditions on Venus are extreme, therefore the probes only survived on the surface for a duration of 23 minutes (initial probes); and up to about two hours (final probes).


An advanced instrument landing system is up and running at Belfast International #Airport after being successfully installed by #NATS. #aviation #avgeek #Belfast

11kW of renewable energy is being installed at an airport in Portugal as part of an off-grid system to power the instrument landing system (ILS).

For more than 50 years, NASA's robotic deep space probes have carried nuclear batteries provided by the U.S. Department of Energy. Even the crewed Apollo moon landings carried nuclear powered equipment.

GPS #satellite - For decades precision guidance for #aircraft approaches have been largely one size fits all, with an Instrument Landing System (#ILS) transmitting a radio beam into the sky for aircraft to follow and land safely, providing a single, safe, approach path to follow. Change is on the way with #GBAS.
