Why? Why would they do that? Meanwhile, look at how far Starship has come in such a short time: Ah right, I wasn't really paying much attention to the video tbh - just the increasing size. Casually thought it was a future SpaceX design. Its still difficult to imagine something bigger than the Statue of Liberty weighing 5000 tons being lifted into space. Yeah a lot has happened in the past 20 years after a period of stagnation, hopefully it won't be too much longer before we look up at the Moon and think someone's up there right now. The last time that happened I'd not long been born. Carl Sagan 1 Link to comment Share on other sites More sharing options...
Wolfie Posted March 16 Share Posted March 16 17 hours ago, Carl Sagan said: He's always said no, for the same reasons why he hasn't gone into space at all yet. We're at such a critical juncture in Human history that if something happened to him, it would still set us back decades (or potentially forever). For the same reason, SpaceX is privately owned to prevent shareholders taking control and deflecting the company from its mission of colonizing Mars. Eventually, he wants to go to live on Mars.

Carl Sagan Posted March 19 Author Share Posted March 19 Things are starting to ramp up properly. COO Gwynne Shotwell was talking at a meeting today and said 6-7 weeks until Test flight 4. She added that key things for this test would be to get closer to landing both the booster and the Starship, so they wouldn't be carrying and launching any Starlink satellites just yet.

Carl Sagan Posted March 25 Author Share Posted March 25 Here's Ship 29 having an engine test in the run-up to the coming fourth Integrated Flight Test: Analysing Flight 3, it seems the team had significant problems with stabilizing Starship on reentry, so that its heatshield was properly positioned. It was pitching and rolling all over the place, exposing the unprotected areas to the surrounding plasma - hence the loss of vehicle quite early into the descent. Finding a solution is likely the biggest objective of Flight 4. In the early tests, when it was just the Starship on its own, flying up and then bellyflopping back down, this wasn't a problem as it was beginning from a stationary start. But now Starship is coming in at 'orbital velocity' it proved harder to maintain stability first time around. In Flight 3 the team decided against a deorbit burn to slow the ship, because of the rolling. I expect they'll be keen to do this next time around. maxjam and TigerTedd 2 Link to comment Share on other sites More sharing options...
BatRam Posted March 26 Share Posted March 26 if im not mistaken the amount of radiation on mars is the reason they said it could never be done. And id rather he put his money into fixing this world not letting it go to ruin and then buggering off somewhere else. I wrote a song about it years ago called locust of man.

And id rather he put his money into fixing this world not letting it go to ruin and then buggering off somewhere else. I wrote a song about it years ago called locust of man. Love the song. "They" (the Mars naysayers) might have said that about radiation, but they're completely wrong. We're protected from some radiation on Earth because of our planet's magnetic field, created by a molten iron dynamo at Earth's core. Mars used to have a similar dynamo, but being smaller it cooled to the extent it no longer works. However, there are LOTS of solutions, some of which will be deployed at different times along the colonization timeline. Due to its historic magnetic field, areas on Mars already have a stronger magnetic field than Earth's and might be sites for early settlement. Then, rock provides shielding. Other early settlements will be built inside collapsed lava tubes or into the walls of canyons with rock above. Water is also a great radiation shield, so some cities will have lakes built into their roofs, with fish etc for food swimming above the settler's heads. Overall, the risk from radiation only leads to a small increase in cancer risk, but even so Mars genetic engineers will work to reduce this. Then, moving on, it will be possible to create an artificial magnetic field for Mars. One suggestion is to place a large magnet at the gravitationally stable point between the Sun and Mars (called L1). A magnet only a quarter the size of those already in use at the Large Hadron Collider at Cern would probably suffice. We just need to work out how to power it at that location. So these problems are surmountable. And definitely not on the critical path to Mars colonization. maxjam, BatRam and TigerTedd 2 1 Link to comment Share on other sites More sharing options...
