..., and around five minutes behind NOAA’s Suomi-National Polar-orbiting Partnership (Suomi-NPP). Whereas MetOp and future MetOp-SG satellites fly on a mid-morning orbit (09:30), this early afternoon orbit has several advantages for the science returns...
... radar team utilised that as the spacecraft is in polar orbit around the moon, it would always cross above the lunar poles on each orbit. The dormant Chandrayaan-1 was predicted to complete one orbit around the moon every two hours...
...between 300 km and 900 km altitude…As these debris fragments are in polar orbits, they are a potential threat to satellites in all orbital inclinations at these altitudes,” says Langbroek in his analysis. India’s ASAT test is not the first to provoke...
...that the modified rocket was heading north for a near-polar orbit. Over time, this north-south flight path would ... remote sensing and/or long-distance observations of other objects in orbit, writes Bart Hendrickx, a long-term observer of the Russian...
...6 March. The principal effect of the missed thrust is to make the initial orbit larger, so the spaceship will need more time to gently adjust to a circular, polar orbit at 13,500 kilometres (8,400 miles). It will reach that altitude on about 23 April...
...goal is to capture a heavy, ESAowned item of debris and remove it from an altitude of 800-1000 km in a near-polar orbit. Justified intervention In conclusion, and in order to determine whether an operation of ADR or OOS on a non-cooperative satellite...
