Antares First Launch Successful

Mon Apr 22, 2013 2:08 pm

I can't believe after 17 hours no one started this thread... please mods delete if duplicated...

Orbital Sciences finally managed to get to the bottom of the countdown and performed what looks like a fully successful first launch of the Antares rocket, the second privately developed vehicle (after SpaceX's Falcon) to get to this milestone under the COTS program .

Images of the launch here.

Well done Orbital and NASA! Looks like the COTS approach is working out nicely indeed...

This is a demo fligh with a simulated payload (not a for-real Cygnus capsule), but an actual rendez-vous mission to ISS (I don't know if a docking is actually planned, pending completion of orbital tests) is scheduled within year end: isn'y this an awfully ambitious timeline?

I was following it. Great news and FINALLY!

Actually I am reading they plan one in July time frame. And that supposedly included a docking with the ISS, I thought they needed to do a "fly-by" first, so that would mean another flight earlier? We have to wait and see if they make it.

I find it interesting that OSC built a facility on Wallops Island since it is higher up and there for requires more fuel (depending on the orbital requirements, I know, perhaps for ISS launches it is not a disadvantage).
I know the OCS system does not provide for down return and the capsule will just burn up in the atmosphere (so they have a lighter capsule) but what are other basic difference in the SpaceX and OCS systems? Fuel? Stages?

OCS operates much like Boeing and LockMart. They use outside contractors to build much of their craft. The engines came, originally, from the Soviet Union, left over from the N1. The first stage was built by Yuzhnoye in Ukraine, which also builds the Zenit. The 2nd stage is a solid, which, seems a bit odd, but must work.

SpaceX builds almost everything in house. They control everything. That's the main difference.
