    There have been many articles lately about how SpaceX fuels their rockets, and how it will apply when they start launching people. Traditionally, fueling is completed first, then people board the rocket. This way, people aren't stuck inside the spaceship in case a bad accident happens during fueling, as happened to the last (cargo-only) Falcon 9.

    SpaceX, however, fuels the rockets as close to launch as possible. This is because they super-cool the fuel, and want to leave as little time as possible for the fuel to boil off before launch. SpaceX plans to have people board the spaceship before fueling the rocket because of this.

    There have been many, many articles written about NASA not liking this plan. But I believe that SpaceX's plan is actually safer. The people board the rocket when the rocket contains no fuel. There's no arguing that this step is safer than boarding the rocket while it is already full of fuel. In addition, there will be support personnel to help astronauts board the rocket, and those people are also placed in danger. So this first part of the process is safer for both the astronauts and the support personnel than the traditional process.

    SpaceX then fuels the rocket after the people have boarded. This part is inherently more dangerous, but at least at this point the danger is only to the astronauts - no support personnel are in danger. So it does put fewer people at risk. In addition, I believe this risk is offset by having the people on a Dragon spacecraft - a spacecraft with the ability to perform a powered abort. If an anomaly is detected (such as the "fast fire" that took out the last rocket), the Dragon can launch away from the rest of the rocket, saving the crew and cargo. I think in the end that SpaceX's proposed process will prove to be safer than the traditional boarding process.

          When SpaceX has a successful launch it is usually reflected on TSLA stock price.

          I'm interested to see if the excitement has worn off before the Monday trading day or if it will drop as profits are taken from this big run up.

          I am stoked that it went off without a hitch as well. It just makes you smile when you watch and hear the cheers from the employees.

          They are building huge radio antennas on the island that are all new as well. Apparently to assist with docking with the space station.

            Relaunch, Relanding, Satelite delivery, Farrings landed; Job done!!!!! Amazing day. They are going to use six more this year and want to turn around boosters in a day by next year. Cost could drop by a factor of 100. Elon working on saving our planet and opening up the solar system for our kids. H.. S..!!

              I thought that was a joke when I saw it on Reddit. I mean, I knew SpaceX wanted to do it _eventually_, but it sounds like they actually did it (or attempted to do it) yesterday!

              Do we have any more details? Any pictures of the recovered fairings? Did they actually have helicopters capture them, or did they just let them splash down for this first test?

              Editted my cmment as I hadnt seen what Elon said during the press conference. Said the farrings have boosters and cotrolable chutes. They landed in the ocean this time. They havent said if they were recovered. Elon said that they will land on a bouncy castle in the future and be reused as they cost six million. I guess some kind of inflatable barge? Also said might try to recover second stage.

              Really?
              Interesting. I know at some point he said that they weren't going to bother trying to recover the Falcon 9 second stage - that they'd wait to implement second stage recovery for a follow-on rocket.

              But maybe "Falcon 9 Block 5" *is* that follow-on. [​IMG]

              He said it in a half joking tone. If you miss and it blows up it was going to blow up anyway. A lot of comments on reddit about how they need to do this to get to rapid reusability. Press conference on youtube if you are interested.

              The microphones weren't working, so you need to turn the volume to maximum to make out anything.

              The press conference was interrupted at 12:50 with news about the fairing.
              Fairing was found intact (well, each half was intact) and floating in the ocean.

              The fairing costs $6 million. Has the great comment of "if there was a pallet containing $6 million cash falling out of the sky, would you let it burn up or try to recover it".

              He also says that the they didn't originally intend for the F9 to have a reusable upper stage. Then says might as well try to recover it, since even if you fail, it was going to blow up anyway.
