The design point was to be a single spacecraft that would refuel other spacecraft in orbit as a satellite-servicing demonstration.
This meant that a single spacecraft could sample multiple sites on any given NEA.
But now, instead of a single spacecraft surrounded by a reddish glow, there were two, three, five of them, in a chevron formation, fairly even.
These would be assembled into a single spacecraft in Earth orbit.
On board were seven crew members - the largest flight crew ever to fly on a single spacecraft at that time.
Lunex was a "direct landing" mission, in which a single very large spacecraft would fly to the Moon, land, and return.
It was the second mission (after STS-7) to fly with a crew of five, the largest carried by a single spacecraft up to that date.
Each consisted of a single unmanned spacecraft designed and built by Hughes Aircraft Company.
A single spacecraft of the line gives total air superiority when there is nothing against it but flyers.
In its center stood one tall building and a single spacecraft.
