Animal is a Ram Posted July 27 Share Posted July 27 3 hours ago, TigerTedd said: Why are they even bothering? They should probably just accept the fact that Elon beat them to the punch. Suck it up and just hire his network it would be like BT putting phone lines all over the country, and then another company putting a completely different set of phone lines all over the country. It’s a mess. How many satellites do we want up there? Not quite phone lines, but since most ISPs use BT lines - Virgin Media did it pretty successfully. Obviously much easier than launching dozens of satellites. It is a measure of Elon can get some things right though. Link to comment Share on other sites More sharing options...
Stive Pesley Posted August 5 Share Posted August 5 Really good article about the original Lunar Rovers (53 years since we first drive an EV on the moon) https://www.theregister.com/2024/08/03/moon_buggy_feature/ Especially the bit about "range anxiety" being if it broke down too far away for your oxygen supply to last the walk back 😂 Link to comment Share on other sites More sharing options...

Given the rate at which satellites and other space hardware have been deployed on the last decade, I'd say it's the tip of the iceberg.

Carl Sagan Posted August 13 Author Share Posted August 13 Looks as if Flight Five will be around the end of the month: Were this a similar mission to Flight 4, no permission would be required from the FAA. The fact that we have to wait for a reasonable period indicates that the attempted catch by the launch tower chopsticks is still going ahead. Excitement guaranteed!

Meanwhile, I published Robert Zubrin's new book last month, on Mars settlement, and there's a good in-depth review of it here, explaining why it's so important for Humanity. https://quillette.com/2024/09/03/life-on-mars-space-elon-musk-starship/ Still no news on the next Starship flight test. My suspicion is that SpaceX are getting 2 imminent crewed flights out of the way first (Polaris Dawn and Crew9) before turning their attention to the Starship. Plus they've been working round the clock at Starbase, Texas, on strengthening the launch tower to catch the booster when it returns. Link to comment Share on other sites More sharing options...

As the reviewer says " it’s irresponsible to hypothesise about tens of thousands of humans being safely born on Mars." It's true one of the key things we have to determine for the future of Humanity is at what level of gravity is it safe to be pregnant. I would build rotating space stations now (artificial gravity) to determine this with primate experiments. Pretty horrific, but what's the alternative? Maybe that's the rationale for this scene in ad astra (as I can't think of another one): But something to always bear in mind, is that technological progress never happens in isolation. As one technology progresses, so do others. If it weren't for regulation we would be much closer than we are already to having artificial wombs. And think what an amazing, freeing technology that would be for women who are keen to use them. Already we can look after very premature large mammals, while the only reason we don't take human embryos further than we do now is regulatory. When it comes to a matter of survival or not, Martian scientists can bridge the gap and have artificial wombs in centrifuges (replicating Earth gravity), so there is a solution. Personally I would expect babies to be able to be brought to term in Martian gravity, but we won't know until we test. And it is probably the biggest blindspot in Robert's book. But because a solution will be found, it isn't crucial to the argument. Link to comment Share on other sites More sharing options...

Zero. Just think, with zero gravity after breastfeeding multiple babies, those fun bags wouldn’t droop down to their knees. Win/Win I say!

Carl Sagan Posted Tuesday at 22:21 Author Share Posted Tuesday at 22:21 Starship has been ready for its next test flight since the start of August, but America's Federal Aviation Authority (FAA) say they won't be able to grant a licence until November: Starship is the critical path for America's Artemis mission to return to the Moon, which is running out of time to be ready before Chinese taikonauts land there. Then, whoever controls space controls the future of Humanity, and if this continues that will be China too. Congress has the power to step in on the grounds of vital national asset and infrastructure, so I hope senators are looking at doing that. SpaceX must be REALLY frustrated and at the end of their tether to post this publicly. It's a big escalation. Link to comment Share on other sites More sharing options...
