Fscking idiots. SMS is NOT SECURE! They had five years to work on the problem, and this is what they came up with?
Hmm, actually from rewatching it, maybe it was still in its descent phase. It's common to point downwards and power the craft down to the ground, and then level out when you near the ground. Maybe they had unexpected momentum or loss of low speed maneuvering ability...
Regardless of how much ground crew (an expense, by the way, that Airlander is designed to minimize) you have, blimps are not supposed to land nose down. This is a Problem(TM) that needs to be investigated and fixed.
Sigh, not this "blimps causing a critical helium shortage" meme yet again....
A design like Airlander 10 is fundamentally a lot more resistant to the common problems that plague blimps during landing, such as susceptability to winds. It has less inherent lift, a smaller cross section, and more ability to anchor itself down with its fans. However, something clearly did not function correctly here. A blimp should never nose down like that. Either lift or thrust was for some reason configured wrong.
Indeed. I saw in some of the pictures from earlier a big gash in the envelope that they were putting a temporary patch on. And the crash ripped open the compartment that contains a lot of electronic equipment.
That would have been an unpleasant day with hydrogen. :
Honestly, I think James Webb just found its first imaging target.
based on my last couple phones, the last update that my provider pushes out (which I cannot say no to) intentionally wrecks the thing. battery runtime drops like a rock (my Note 4 turns off at 27% battery remainining now), and my Droid 4 became unusably slow and hot-running, taking longer to tell me that someone is calling than is allowed so I could never answer to talk to someone, and apps were unbearably slow, with several no longer even able to load.
With this belief, of course they don't want to be bothered with updating old phones. They've already at some point done their last update with the intention of forcing people to stop using that one to buy a new one. Funcitonal updates at this point are of course not part of the plan at all, let alone security udpates or anything useful.
I need to start rooting and getting "alternative" OS deliveries to see if that helps or not...
Right, so they're going to reengineer every last subcomponent of every last part to withstand cryogenic temperatures, specifically for production in the tiny volumes needed in the space industry? Just for the inconvenience of reusing an upper stage?
Again: contrary to would-be-rocketeer imaginations, launch costs are not the be-all end-all of expenses when it comes to space. Engineering and low-volume production is killer. Mission designers always heavily stress TRL (Technology Readiness Level) of all components, as it's such a key determiner of mission cost. If any plan you propose involves "just reengineer everything", you do not have a plan.
What you need is: Oxygen, Radiation shielding, Water, Food, Power and some gear.
Yes, it's totally that simple! The ISS has hundreds of thousands of parts, but only because congress insisted on adding thousands of Machines That Go Ping for no good reason. And random objects totally love being submerged in liquid oxygen and liquid hydrogen. And empty tanks are totally easy to haul all the way to orbit when pre-loaded with fittings and jackets and extra tanks. And building things in space (including bloody *welding*) is such a nothing job that totally costs nothing!
Meanwhile, in the real world...
The tanks will serve as basic habitats etc., you could grow food (wasn't this successfull?) in one of them to replenish your oxygen supply.
Everything which does not need to be inside, you leave it outside,
What plastic are you thinking of and at what thickness, that is compatible with liquid oxygen, retains flexibility at LOX (or worse, LH) temperatures, and withstands the pressure, all without adding a massive mass penalty? How is the plastic supposed to deform around every little structure in the habitat (aka, not face multiple atmospheres of asymmetric pressure)? What sort of hardware are you thinking of where every last element is just fine with being frozen down to LOX (or worse, LH) temperatures? How many man hours are you thinking of to "rip out" the giant bag through the tiny docking port (after having to detach it where it's carefully bound around each element? Unless you were thinking of having it fully loose inside there, which is even more problematic. Where's it supposed to go on the ISS? If you're doing the (larger) hydrogen tank, how 100% sure are you that you're not making an explosive fuel-air mixture, given that hydrogen burns at just a couple percentage concentration? How positive are you that you've fully vented every last nook and cranny? And on and on and on.
Wet workshops were worked on during the Apollo era. They were ditched for dry workshops because it's easier, cheaper, and more functional.
Shuttle ETs never got up to a stable orbit. It would have been possible to use the OMS to take them up there, but then the Shuttle would have had basically no payload capacity on that mission.
Of course, that's one of the lesser problems with the concept. Often proposed, often investigated, but never considered worth throwing serious money into.
Because all of the hardware that goes in a habitat is just totally compatible with being submerged in liquid oxygen and/or liquid hydrogen?
