That would have been great with a 5:56 AM launch. Even now, from the ground you could see booster thruster firings after stage separation.

The CRS-28 second stage was using the new short nozzle. I may have read it but forgot. Why is that short nozzle being used as opposed to the original nozzle?

View Quote I wonder if it's either common to the non-vacuum engines, or if perhaps they're able to cut it down from otherwise rejected nozzles. Keep in mind that SpaceX has such an immense cost advantage that there's often a TON of performance to spare over the launcher that the satellite was really designed for. Some of these payloads are really light for a vehicle of F9's capability. You'd never see them fly on an Atlas or a Delta, too expensive, but F9 is so relatively cheap that they can displace a smaller launcher. |

View Quote IXPE will probably be the smallest payload that Falcon 9 flies outside of ride-share stuff. 370 Pound payload mass. It was originally supposed to go up on the Pegasus launcher but SpaceX was able to plunk it into an equatorial orbit with a launch out of Canaveral which may have performed the worlds largest power slide. https://en.wikipedia.org/wiki/IXPE I know it’s been said before many times but... The flexibility of Falcon 9 and Falcon Heavy is truly impressive. Watching them do their thing is some of my wildest fantasies coming true. For a very long time I thought that we were going to have to wait until someone cracked gravity manipulation before we could put this much hardware into so many orbits. |
