  1. Thanks for an awesome overview of what's happened so far with this moon-landing. I'd read that in spite of having an X-band antenna on the lander, ISRO faces communications bottlenecks in getting images transmitted back to Earth and processed for release. I wonder if that will be addressed for future missions?

  2. It's mainly that ISRO didn't have any plans in place to deal with a crash or adverse event. So that's what led to a muddled response by them afterwards. ISRO really are mainly just a bunch of scientists & engineers, and not a bunch of PR managers. But they'll learn from this and evolve - all part of the growing process.

  4. Well, there was something called INCOSPAR (Indian National Committee for Space Research) created in 1962, which was the predecessor of ISRO (Indian Space Research Organization)

  7.  @E9X330  - I agree - I wish they'd avoided use of the phrase "hard landing", which tends to confuse or mislead, and had instead used the word "crash"

  8. As far as I remember, Chandrayaan-3 was already orbiting the Moon by the time Luna-25 launched. So technically, it was already there even if it hadn't yet landed. But fair enough - Luna25 contacted the surface first.

  10. @Thomas Hancock Von Braun didn't get to pick where V-2 rockets were aimed, he was just a peon. It's easy to invoke the Nuremberg critique, but it's a lot different when your own neck could face a firing squad in wartime. Who's to say that any of us would have behaved differently had we been in his shoes? He just gets picked on because he became a high profile name through Apollo. It was the German high command who shortsightedly targeted London, just as it was British commanders like Bomber Harris who went after German population centres in retaliation.

  14. Well, "space tourist" is a mainstream term for private astronauts these days. As more private commercial missions happen, perhaps some new terms will be coined to describe those engaged in more serious undertakings than merely having a joyride. I wonder whether these missions were entirely Isaacman's idea, or how much they were jointly conceived by himself and SpaceX, or what?

  16. ​ @IstasPumaNevada - let's keep the hate away, man. Some people are very successful in business, and we shouldn't hate them for their good fortune. Should we also hate people for being athletic, beautiful, smart, etc? I think it's great that Jared has the courage to risk his own neck on these early days of private spaceflight, which can help to make things safer for future travelers.

  17. They should've had Von Braun talk about his book, "The Mars Project", which may have inspired a certain private space entrepreneur to strive for the Red Planet

  22. ​ @jbirdmax - thanks very much for your reply. So that's what I'm interested in -- is it that the ability of the red blood cell to hold oxygen is what's specifically being destroyed here, in space? Because it doesn't seem that absence of gravity could damage hemoglobin, which is just a molecule. It would be interesting if researchers could test red blood cells under various gravity conditions (zero-G, normal G, high G) through various experiments here on Earth, to see what the effects on red blood cell lifespan are. Can red blood cells exposed to periods of Zero-G then later recover their lifespans back in normal-G? Or is this alteration of the red blood cells ('destruction') permanent and irreversible? Personally, I'm suspecting Cosmic Radiation more than anything else.

  27. India certainly hypes its missions on Twitter. I think it's just the crash stuff that they weren't forthcoming on, probably because they were embarrassed. And mainly, the crash was an event they didn't plan for, so they had no plan in place to deal with it.

  31. I wonder if we could have manned helicopter-type transportation vehicles on Mars one day. What would it take?

  32. So what exactly was it that exploded? Was it composite tanks which ruptured inside the steel hull? Or was it the steel hull itself which was somehow being pressurized and then ruptured?

  33. ​ @Tyr Kukulkán - alright, but details matter. What exactly is happening to the blood cells in space that makes them 'dead'? Are we saying that these blood cells are rupturing at some increased rate? Are we saying that they're being damaged in a way that prevents them from carrying oxygen? I'm not sure what a 'dead blood cell' is in this context.

  35. Well, Scott - it looks like your coverage is timely, because India has just announced its intention to launch its first manned spaceflight mission ("Gaganyaan") by 2022. As far as funding is concerned, the initial budgetary estimates being given are roughly 9,000 crore rupees (9 x 10^10)

  36. @Scott Manley, Just a clarification for you: That plunge at the end was a deliberate drop test meant to study the G-forces for impact, in case some problem were to happen with the parachutes. They did do preliminary drop tests with a helicopter, but this was a cut-off drop test done at a higher speed of descent.

  37. ​ @Mike - "most qualified candidate for the job" vs "businessman doing businessman things". I'll say that if you have the money, then you're doing a business transaction, like any passenger on a flight. Are Jared Isaacman or Yusaku Maezawa any less worthy because they themselves paid for a ride instead of being selected by someone else who's paying for the ride? Ideally, isn't part of the purpose of private sector spaceflight to remove these distinctions, and facilitate access/travel to space for anyone with a desire to go, without gatekeeping or judging whether they're worthy of the opportunity? If I want to fly to Japan (or Scotland), no airline's going to judge my motives for alleged merit, as long as I'm paying their ticket price. Hopefully one day anyone will be able to experience space travel, without having to pass some merit test (other than perhaps medical fitness). The power of free market economics applied to spaceflight is that it will permit all sorts of novel and unforeseen/serendipitous developments, just from the number and variety of participants choosing to participate in it.

  40. :face-blue-smiling: ISRO personnel, including the current ISRO chairman, have given their explanation of what went wrong with the Chandrayaan-2 lander. They said that as the lander descended, the attitude deviations ("errors") began accumulating faster than expected, necessitating larger sharper corrections by the thrusters. At the same time, there was a bug in the software that manifested itself due to these larger sharper corrections being required. This software bug was not allowing for larger corrections by the thrusters beyond a certain amount. Had the attitude errors/corrections been smaller in size, then the software bug would not have been encountered, but because they were large enough, that software flaw came into play. Therefore the lander was unable to properly perform the required attitude corrections on the way down, causing the resulting crash. ISRO personnel refer to this problem as "dispersion" handling, meaning that those attitude errors/deviations were larger (ie. had a larger dispersion) than anticipated, which the software was unable to handle. That has now been corrected, along with other improvements and upgrades made to this Chandrayaan-3 lander.

  45. So were 3 engines supposed to fire during final vertical landing approach, or were 2 engines supposed to fire, or what? So was the root cause of the landing anomaly mainly just the loss of pressure in the fuel header tank?
