Orion service module
I see they have put out a press release about fitting the first test heat
shield to the capsule, and in that release they mention the service module. I've heard little about this piece of hardware recently and wondered what was being launched on this unmanned test. Is it just a dummy, or is it too, now built and under test? Description of the heat shield seem very familiar to me, having been around during Apollo! Just bigger!

Orion service module
You have not been reading the mail then.
The donut thing is a test for mars re entry, nothing to do with Orion. The Orion is going to be launched on a heavy lift launcher with service module in December and go very high and re enter very fast to make sure everything works. All the other tests have been done already I don't think the idea is to use this for ISS, though arguably a docking adaptor could be use for it. Its just a crew module, one assumes that we are effectively going back to the old days with bolt on living module and landing module for planets etc, and a service module on the back to power everything.

Basically an aerodynamic brake that probably burns off after a while, leaving the cleaner capsule shape. I have absolutelty no idea what will be done with Orion. As far as I am concerned, it is a Pork project, make work project. Not even sure if it will ever launch to ISS. And certaintly not to other planets. I've heard little about this piece of hardware recently and wondered what was being launched on this unmanned test. It is a fair bet the first one would be an unmanned test. Not sure if it would go to orbit and renter from orbit, or just be dropped from high altitude to test parachutes etc. |

Simplistically it's the back end of an ATV with the Orion replacing the pressurised volume. Anthony |

That may explain then why only one more atv is actually budgeted for.
