Such is the case with Orbital's Cygnus, which was awarded a NASA
contract today. It also will use the MPLM design.


I've been sick with a nasty cold for more than a week, so I'm not as up to
date on these developments as I'd like to be. I'm going to have to play
catch up here...

There isn't a whole lot of information here. In particular, is this
system entirely throw-away, or is there a reentry vehicle? If there is a
reentry vehicle, is any returned component reused?


From the "artist's rendering" this thing looks like it's completely
disposable. How disappointing.


Actually, an article at NASASpaceflight.com says that it "will be able to
return 1,200 kg of cargo from the ISS to Earth". That's encouraging, but it
doesn't sound like a whole lot of down mass per mission.

Personally I'd like to see SpaceX's Dragon pan out and start flying. The
"growth option" to a manned capsule is very appealing.

It isn't "per" mission. The return vehicle is different from the MPLM
carrier and has less up mass. Down mass is for experiment samples and
not ORU's/racks
