  1. The upper stage deorbiting in the upper left of the video is really cool
  2. Go for IVA suit removal in a few minutes, looks like a perfect launch
  3. Fantastic launch for now, almost time for the landing
  4. Crew is inside Endurance and ready to launch, T-2 hours fifteen minutes
  5. You aren't the first person I saw making this comment, interesting. And yeah, dragon is only a bit smaller than the Shuttle cargo bay (iirc, the fins actually make it bigger than it), so even if that's with KSP scaling it should be very similar to reality
  6. Oh, with "airlock in the trunk" you shouldn't think it as something like Spacelab with shuttle, but more as the Apollo Soyuz docking tunnel: Dragon would deploy it from the trunk, make a 180 degrees rotation and dock it with the docking port in the nose where it can be accessed. A problem with this is that the weight constraints in the trunk are much more severe in crew missions due to the aerodynamic forces during abort, but that is something that could be solved by attaching the payload to the ascent stage instead of the trunk (again like Apollo Soyuz and every crewed Saturn V launch)
  7. I mean, yeah? You seem to be under the impression that the astronauts need to reach Hubble's docking port - that is not the case. The port that the last STS mission mounted on it is not an access point or even a hatch, it's only usable to attach a spacecraft and stabilize it; Hubble's instrumentation and gyros can only be accessed from the sides, while the bottom of the telescope is mostly just where a Canadian can grab it or a capsule dock with it. A service mission with either Orion (original proposal), dream chaser (2017 proposal) or Dragon (current proposal) would happen this way: after the spacecraft has connected with Hubble's port, an astronaut would always make a tethered EVA from it (in Dragon's case from the docking tunnel in the front, not in the back like you're suggesting), move to Hubble's bays on the sides, open them and replace/add what's necessary. From a hardware standpoint, the service mission seems very feasible: as the EVA systems will already be tested by Polaris Dawn the main system that needs to be added is the rear docking port and the associated sensors. The main question marks are the cost and the astronaut stabilization system for a safe gyro replacement
  8. Jared himself said the opposite as i linked above, and the thing would be even harder than you make it: there are no thrusters and fuel lines at all in the trunk, which means you basically need an entirely new propulsion module. On top of that, docking nose first means you can't EVA with even more mods, as currently the docking tunnel is the only way in and out of a Dragon; if you want to avoid that you need further changes, allowing the ingress door to be used in space and suited up in a vacuum
  9. How it should look probably (not my account, the Dragon hatch should be probably open while the Hubble cover should be closed)
  10. Some info from Jared: So, no additional fuel needed for the mission but the one in the Dragon tanks and the docking will happen backwards, with the tank. This allows the deorbit thrusters to be used to boost it and the crew of the capsule to come out of it from the usual docking hatch instead of modifying the ingress hatch for it. Also, in case anyone's curious, a possible working name for it is "Polaris Rising"
