Spekulatius Posted May 30, 2020 Share Posted May 30, 2020 Watched the launch live with my oldest son. Quite a moment to share. It’s cool to watch, but I watched Apollo launches as a small kid in front of a black and white TV. I really thought that at this point almost 50 years later, we would be cruising with ion drive powered space ships around Jupiter. Some where along the way, we dropped the ball on space exploration.

Castanza Posted June 2, 2020 Share Posted June 2, 2020 A small step for mankind, a large step for capitalism. I watched the ISS fly by the night of the launch. You could actually see the capsule trailing the station as it was preparing to dock. Pretty cool to see. Link to comment Share on other sites More sharing options...

SpaceX and Tesla are two different companies. Tesla is a public company that makes cars and SpaceX is a private rocket company. SpaceX has been working towards sending Astronauts to the space station for a long time. This was not a scheme cooked up by Musk to divert attention from Tesla. Also the Earth is a globe and Stevie Wonder is blind. Link to comment Share on other sites More sharing options...
muscleman Posted June 2, 2020 Share Posted June 2, 2020 Could anyone tell me why it took 19 hours for the dragon to dock ISS? It seems to me that it should need to fly a very long distance as both dragon and ISS are just circling the earth Link to comment Share on other sites More sharing options...

Cigarbutt Posted June 2, 2020 Share Posted June 2, 2020 ^Once the Crew Dragon enters an orbit, it becomes a different ball game. The flying Dragon is made to be as simple as possible and incremental adjustments in speed need to be made along raising the orbit. While it may appear that the Dragon (and the ISS) does not go fast, the speeds are tremendous. Watch (and listen) the following relevant video when Mr. Chris Hadfield answers a question while in space. Take a look at the microphone he's periodically holding to adjust the position. The microphone looks likes it's immobile but in fact, in a relativity way, it is moving at an amazingly high speed. The process appears simple but it's anything but. From Einstein: "Everything should be made as simple as possible, but not simpler". :) You may remember that i had tried to share with you a rocket launch science theory of interest rates but it seems that you had lost interest.

It seems to me that it should need to fly a very long distance as both dragon and ISS are just circling the earth The relative speed between the ISS and the dragon module decreases, as the dragon comes closer to the ISS Orbit. That’s why it takes the dragon so long to get to the ISS station. Link to comment Share on other sites More sharing options...

And known that saying anything Tesla-related could stoke strong reactions. I'm not trying to create a conspiracy. Personally, I like SpaceX. I don't like Tesla. "I think Elon Musk is peculiar and he may overestimate himself, but he may not be wrong all the time". That's all. Link to comment Share on other sites More sharing options...
rb Posted June 2, 2020 Share Posted June 2, 2020 Seriously guys? This isn't anything amazing, we didn't discover space flight, we've been sending rockets into space for 50 years. This time we just made some money. I'm sorry but it's not exactly a momentous, world shaking event. Link to comment Share on other sites More sharing options...

RB, I recall watching an interview with the Boeing CEO Muilenburg, believe it was on Bloomberg, few years ago. It was a good interview I thought at the time. He was the first non-GE leader at Boeing since the merger from McDonnel Douglas and he rose up through the engineering ranks and he was bold. In the interview, Muilenburg made a few bold and fun statement (at the time) poking at Airbus and SpaceX. Interviewer (David Rubstein) asked him what he tells his mother. Muilenburg says something along the lines of only flying on Boeing products, implying other products from Airbus are unsafe. He also poked fun at SpaceX (maybe at a different interview) when he was asked about Elon Musk' stunt of throwing a Tesla in space that Boeing will be the company that not only make it to Mars ,,, and will bring the car back on its way back. Bottom line, fast forward by a few years, we had 737 MAX crashing, the entire fiasco as to how it was handled, and then their debacle Boeing space launch etc. etc. Muilenburg was just manager squeezing the cash machine through buybacks … he was not amazing. Elon was and is amazing. Naturally in hindsight his idea of re-using rockets seems like an obvious thing to do. Airbus was and is amazing by insisting to be boring and risk averse. Boeing was not amazing. Link to comment Share on other sites More sharing options...
meiroy Posted June 3, 2020 Share Posted June 3, 2020 Spectacular achievement. I've been following SpaceX for years. It's not just that they got people to the ISS, it's the HOW, the way, the technologies used. Elon Musk, without a doubt, is a genius. There's nothing right now that gets close to it anywhere else in the world. Another reason why this is so significant is Musk's vision and end goal. This is another step in order to achieve it.

Airbus was and is amazing by insisting to be boring and risk averse. The idea to reuse rockets For cost savings is very old, at least early 70’s. In a way, the Challenger was build around this concept. However it’s not easy to make it happen. For me, the most amazing part is to bring the booster rockets back on their feet on a drone ship.

It was something like $80M per astronaut so $160M per launch with US astronauts. As an American I had heard/read very little about SpaceX's primary competitor Arianespace but the price war between the two is fascinating and it will be interesting to see what Arianespace comes up with. Just the ability for US companies to launch from the Cape as opposed to French Guiana has to translate into significant savings. https://en.wikipedia.org/wiki/Space_launch_market_competition In competitive bids during 2013 and early 2014, SpaceX was winning many launch customers that formerly "would have been all-but-certain clients of Europe's Arianespace launch consortium, with prices that are $60 million or less."
