  1. I doubt it was a void in the fuel composition, that would likely have resulted in a far more exciting event!

  2.  @andrewlalis  Clearly his cousin understands something about flame chemistry, so he is not dumb.

  4.  @alanrickett2537  For how much longer though? Boeing is starting to lose out to Airbus because it's products are losing the confidence of airlines. However large the company, once it begins to prioritise profit over performance it is open to replacement.

  5.  @blexxy5861  But it is hard to make them light enough to hold pressure, make orbit and return.

  6. I once saw a real time x-ray image of metal being cast. That was pretty impressive.

  7.  @johndododoe1411  They will not use the Vacuum raptors for a moon landing, too much dust throw.

  8. The real issue with hypersonic missiles is the talk of both conventional and nuclear payloads. For most of its flight the missile will resemble an ICBM, including the mid course phase where it is at its most vulnerable. With no way of knowing what warhead is fitted and a greatly reduced probability of intercept in the terminal phase, is a potential target going to wait until it explodes? More likely they will attempt a mid course interception "Just in case." The potential for an accidental nuclear exchange is increased by the adoption of these weapons, much as the introduction of both conventional and nuclear armed Tomahawk cruise missiles raised similar concerns during the cold war.

  9.  @jwschwartz7073  A void or crack would increase the surface area of the burning front, which usually results in a localised and catastrophic increase in burn rate.

  10. But, but.... where are all the fisheye lenses?

  11. I learned about control rods from watching Voyage to the bottom of the sea ^^

  12. I used to follow them, but the more I see the more it feels like a scam.

  13.  @Penningtontj  Yes :) A sudden increase in pressure within a void/crack will likely blow the propellant grain apart.

  17. Oh dear, the sun lighting a rocket from below the horizon - bit of a bummer for the flat earthers that! Spectacular view.

  18. He is going to land it in a crater full of ice, what other colour would it's balls be?

  19.  @maus9777  Don't forget you can land a Starship on earth with one raptor and the moon has one sixth the gravity. Also, with the engines higher on the body Spacex will have to fire several in order to have directional control.

  20. Sell space on the construction of power sats and offer senators the prospect of cheap, clean energy for their constituents. That should focus their minds and loosen their wallets.

  21. What's not to like about this video? Some people are just sad. Keep it up Scott.

  22. Makes me smile the passion with which people will deride someone for expressing a temperature in Fahrenheit, then proceed to give it in Centigrade.

  24.  @Thermalions  We will need that sort of speed soon anyway, just to cope with the advert script.

  25.  @michaeltaylors2456  If the module contained energetic material it must be made safe prior to handling. The operator is wearing the suit because in a worst case scenario one of the energetic components might have partially functioned, leaving it in a highly dangerous state.

  26.  @michaeltaylors2456  It depends what devices were involved, though having photographers so close appears to be poor practice. The scene could have been recreated after the actual inspection ofc, to illustrate the process. As for using a robot, they are a pretty crude technology. There wouldn't be much left of the contents if the capsule were "disarmed" by a robot.

  27.  @michaeltaylors2456  I said "robot" because that is the common term used for devices intended to remotely inspect and disarm items containing energetic material. If by "defusing by robots" you mean intricate wire cutting and removal of tiny components then no, it is not a reality. Reality is the initiation of a disruptor which smashes something, it might be solid material or a water jet, into the device to break it apart. Why would they spend millions of dollars developing a highly intricate piece of equipment to perform a very occasional task when a human can do it with an acceptable level of safety?

  28.  @michaeltaylors2456  I have some knowledge of energetic materials but not spacecraft design and functioning. Without being a part of the program I have no way of knowing what type of energetic devices were used in the vehicle, or what function they performed. There are a great many possibilities; from fully self-contained actuators to miniature cutting charges. What I am saying is that if the vehicle did make use of such devices, then it would be prudent to confirm that everything had functioned correctly prior to handing the capsule over to the scientists. Did they need a full bomb suit? Who knows, possibly. I do know that a task I might have been willing to undertake with a face shield and a pair of gloves can quickly escalate once the risk assessment is passed around.

  30. Just goes to show how far flight control systems have evolved.

  31. I am amazed SpaceX are still working on SN9. If they were in the UK the HSE would have stopped construction work pending investigation of the accident.

  32. No doubt the pre-cooler technology will now belong to DARPA, who were helping fund it.

  34. The British government at the time thought there was more future in supersonic flight (Concord) than satellites.

  35.  @Xatzimi  Not exactly shelved., but I get your point. We used to be massive innovators, but squandered the fruits of our innovation. Now we produce soaps and reality TV!

  38. Full band UV can be a bitch. I worked in a paint testing lab and we had an old carbon arc machine for simulating UV weathering, it was brutal.

  39. I assume the intent was to certify it for Vulcan?
