...of the Dream Chaser® spaceplane, a multi-mission space utility vehicle capable of transporting cargo - and eventually crew - to low Earth orbit. But there is more to the company than this. As Thomas Crabb, Robert Richter and Martin Chiaverini explain...
... past decade, the International Space Station partnership has continually addressed the future of research in - and exploitation of - low Earth orbit (LEO) beyond the lifetime of the ISS. At present, it seems likely that the Space Station will remain...
... path of the photons for most of the way down would solve the problem of signal losses. A satellite in a low earth orbit could easily act as a relay between different ground stations who wanted to communicate securely and wanted to share...
... now under development in different parts of the world for humans to move beyond Earth and low Earth orbit to explore and live in space, on the Moon, on Mars or in orbiting colonies. But leaving home is never easy, and space travellers moving out...
... life extension driving much of this revenue. This new market will be realised, first in Geosynchronous Earth Orbit (GEO) and then medium and low Earth orbit (LEO), through logistics. Those space-based ‘cars’, forever on the road, that have...
