We have to fly our second and final certification mission before we can begin flying Vulcan for national security missions. We will be switching payloads for Cert-2, since they [Sierra Space] are stepping aside to do the right thing for national security.
We have an inert payload, a so-called mass simulator that we had built for Cert-1 as a backup to the Peregrine payload that we did actually fly. That's what we will fly on Cert-2 and will add to that some experiments and demonstrations that are relevant to technology development for future insertion into our Centaur V upper stage.
And then we'll also conduct some maneuvers post the basic mission just to help us better understand the full capabilities of the Centaur V and to measure some of its attributes. It will then go to a disposal orbit to the designated junkyard.
