Fishstick posted:That's a long time to be in space. Isn't the longest time spent in one flight like 400ish days, and that was on Mir which was probably a little more comfortable than a mars orbiter. Not to mention Mir also had the safety blanket of the Earths magnetic field as well. 500+ days in interplanetary space exposed to cosmic rays is a pretty big deal isn't it?

How about a space mission which sets up robotic refueling and fooding stations in a mars earth transfer orbit?

That article mentions another one they tried back in 2000 that didn't go over to well though. quote:A 420-day experiment in 2000 ended in drunken disaster when two participants got into a fistfight and a third tried to forcibly kiss a female crew member Did they really let them have alcohol? That seems like it was a poor decision.

The guy who was on MIR for 437 didn't go crazy. There is a pretty big psychological difference in being holed up as a lab rat in a bunker for an experiment and sent as a true pioneer out of Earth's solar orbit and into history.

On the other hand, early polar explorers trying to find a (supposed) sea passage across the north pole set out in tiny ships for multi-year journeys with no promise of return. There are plenty of physical challenges to be overcome (microgravity's effect on bone structure, radiation) but with the right person/people I think the mental challenges aren't as bad as everyone thinks. Most people couldn't do it sure, but I think there are plenty of people who could. ^^^edit: yes, I agree. Some people just have that explorer/pioneer mindset.^^^

Question. I really like how the recent ISS missions are going for PR coverage, but in scientific terms, how did they pull this off? Is it creative video editing, or is the ISS <> Earth comm been upgraded so far these days that lag is nonexistant? I know I can talk to people several thousands of km away with almost zero lag due to undersea cable, has there been a recent tech upgrade in comms for the ISS? I remember there being distinct lag in the past for interviews, when the actual distance should be less than talking to random people in, say, China (from EU).

Well the ISS is only about ~0.002 lightseconds away I believe, probably less, so under ideal conditions the lag should be pretty minimal. In reality though I expect the signal is normally passed through a lot of intermediaries which extend the distance but add plenty of processing lag to the delay. He could have just pre-recorded it and his video was played in the background though or some other cheat but I dunno.

Or is it? It seems like morale, especially on year+ missions is a big factor. Food variety only goes so far, and with astronauts requiring 2+hrs a day of exercise to keep muscle tension up, they'd need some kind of distracton. I'm not saying it should be alcohol, but I can understand their viewpoint. How do you keep astronauts in a year+ long mission busy within cramped space and limited weight contraints?

Fishstick posted:Question. Well, they normally bounce everything through the TDRS satellites up at GEO, so there's a bit of extra lag. As for the video, it might have been put together afterward in the mix. Or maybe they just let Commander Hadfield set the rhythm, and everyone in the studio followed his lead in "real time" the same way that you could sing along with a recording. But I haven't heard anything definitive. e: welp

Yeah that was definitely pre-recorded and played in. Lag to the ISS seems to be about 3 seconds if you watch a PAO event. Up to TDRS, back down to the ground, via White Sands in New Mexico IIRC.

In reality though I expect the signal is normally passed through a lot of intermediaries which extend the distance but add plenty of processing lag to the delay. Audio lag over 10ms is noticable to the trained ear. 20ms will annoy some casual listeners. Amateur PC audio recording is generally happy with less than 5ms. I've done some harmonica/guitar/drums blues jams over mumble (it's like Ventrillo or Teamspeak, but not quite as awful) before, but it gets pretty sloppy pretty quickly because both parties are connecting to the server with about ~30ms lag for about half a second or two beats off from eachother. edit: nm, that file had been edited to compensate for lag Hadlock fucked around with this message at Feb 23, 2013 around 00:15 |

You can also check out this google search for articles on it from just about everyone. I can't find the AP article I read about it on, but they all touch on the same thing. It's worth noting that this touches on something that's been found all over. Isolation and lack of an outdoors makes everyone groggy. Astronauts don't get enough sleep. It happened on Skylab, it happened on the MIR, and people need to stop deluding themselves that some people just have the pioneer spirit and can overcome this issue. There's a serious psychological problem with long term stays in a tin can that needs to be addressed, or circumvented by removing the tin can from the equation before we can even discuss doing anything serious far from Earth. edit: Wired article had a link to an actual study: http://www.pnas.org/content/110/7/2635

Hell I wouldn't get in a Bigelow capsule to Mars - between the rays and micrometeorites I'd only accept a one way trip where I get to walk on the surface.

Speaking of micrometeorites, ISS-dweller and twitter star Chris Hadfield said something very ominous in his Reddit AMA:quote:Sometimes we hear pings as tiny rocks hit our spaceship, and also the creaks and snaps of expanding metal as we go in and out of sunlight. The solar panels are full of tiny holes from the micro-meteorites.

Im updated the OP news with the stuff going on in the last 12 hours that I have been asleep for, well, besides Chris making lunch, that's just fun to watch. If you think I missed anything important let me know and I can add it. SpaceX To Begin 5 day countdown to launch of Dragon to the ISS. SpaceX on Monday will start the process of wet-rehearsals of their launch program for the Falcon 9, taking the rocket out to the pad, fueling it and then conducting a full launch simulation with a 3 second hot-fire of all 9 Merlin 1C engines. If the tests of that all work out, the rocket will be prepared and mated with its Dragon ready for launch on Friday.  Orbital manage to light up their new rocket! Orbital conducted a 30 second hotfire of their new Anteres 110 first stage booster. It did not blow up. http://www.youtube.com/watch?v=wFj4A2vW3yY Initial review of the test data indicate the primary objectives of the test were accomplished. The pad and fueling systems will undergo post-test inspections and any necessary reconditioning work will be performed. Orbital will then roll out the first complete two-stage Antares rocket to prepare it for its test flight mission, which is expected to take place in four to six weeks. Chris Hadfield makes a JB&H sandwich in space. http://www.youtube.com/watch?v=AZx0RIV0wss This updates not really news but hey its fun thing!

McDowell posted:Nope, cosmic rays. Astronauts going to the moon saw flashes and floaters. The eyesight problems are all similar to patients with cranial hypertension aka high pressure in your skull. That's not something cosmic radiation can do by itself. The body distributes most of the blood in chest and head while in microgravity, so a centrifuge should cancel or minimize the effects.
