... as a failure by the fault detection and recovery logic. Also the whole swing-by scenario had to be re-designed to establish a spacecraft configuration that would minimise power consumption whilst in the shadow. It was not an easy task but we had...
... National Oceanic and Atmospheric Administration (NOAA) has expressed interest in placing a long-duration solar storm warning spacecraft closer to the Sun, yet always between the Earth and Sun, so as to enable rapid warning of an impending solar...
...a planned ‘excursion’ to study the coma structure at distances up to 1500 km from the nucleus, we started to gradually decrease the spacecraft distance to the surface, and by the end of 2015 we were back to closed orbits. This explained the 18-minute...
... flat at 500 in any given year in the range. Therefore, we have 10 ‘serious anomaly’ debris strikes on 5,000 available spacecraft overall in this 10-year period. This gives us a ‘ballpark’ serious historical anomaly rate of one in 500 satellites per...
...several million galaxies will be imaged. Regular observations for instrument calibration and sample characterisation The Euclid spacecraft is equipped with a 1.2 m three-mirror Korsch-type telescope and two instruments, a visible imager, VIS, and the...
.... Engineer Joel Steinkraus uses sunlight to test the solar arrays on one of the Mars Cube One (MarCO) spacecraft at NASA’s Jet Propulsion Laboratory. Interplanetary challenges Interplanetary CubeSats, thanks to their low-cost, could perform highrisk...
