Astronauts Open ISS Station Room

Posted by kdawson on Sat Oct 27, 2007 07:29 PM
from the now-to-hang-curtains dept.
mikesd81 notes an ABC News report that astronauts aboard the ISS have opened the new station room. Commander Peggy Whitson and astronaut Paolo Nespoli delayed their lunch so the event could happen before the station's orbit temporarily blocked the ability to send a video downlink to Mission Control. From the article: "Nespoli... joined Discovery's crew to personally deliver the Italian-made pressurized chamber... Astronauts added the school bus-sized room called Harmony during a 6.5-hour spacewalk Friday, using a robotic arm to lift it from the shuttle's cargo bay and install it on the station. The compartment will serve as the docking port and nerve center for European and Japanese laboratories that will be delivered on the next three shuttle flights. It also will be a power and thermal distribution center, providing air, electricity, water and other systems for the space station. Racks of computer and electronic equipment are already inside the cylinder, which will double as a living space for the crew... The astronauts will have to undo more than 700 bolts [which held down the equipment during flight] to free up the equipment."

              You claimed there is no up or down on the ISS because it is in "zero gravity". My point is that the weightlessness felt by people on the ISS is because it is in constant freefall, not because it doesn't feel the Earth's gravity. If you concede that a plane in freefall still has an up and a down then you must concede that the ISS does too.

              • A few things here. First, when a plane is in free fall, it doesn't have a natural up as determined by acceleration at that point. If you spun someone around, blindfolded, they probably wouldn't be able to recall which way "ground" used to be (unless they have a good sense of direction). There's no acceleration cues (well aside from jostling and imperceptible gravity gradients). Second, immediately before and after this period of freefall is a period of high G acceleration where down is clear. finally, they

                • In summary, anything in freefall whether it be a plane or a satellite, does not have a natural "up" as determined by acceleration.

                  Who said anything about "up" being determined by acceleration? Spin a blindfolded person around and they probably wouldn't be able to recall which way north is either, but that doesn't mean that north doesn't exist when you're not holding a compass. Astronauts on the ISS probably define "up" in terms of the orientation of the ISS. That is a perfectly valid definition for "up" - it doesn't matter at all that they can't instinctively feel which way "up" is.

        • That's in your opinion, as you said. Up and down is in the opinion of those "lifting", and in this article their opinion counts, not yours.
        • Up, in the normal human reference frame, is away from the most powerful source of gravity detectable. Seeing as how the ISS isn't far enough away to be in true microgravity (less than 50% difference) there's very little ground to stand upon if you're claiming there's no detectable source of gravity nearby, about as much as claiming that there's no Up in an elevator.

        • While the fact that they still in Earth's gravity well is pertinent to the "up and down in space" discussion, is it correct to say that they are in almost 1G? This is an honest question as my understanding of Physics is all self taught. As I understand things, there is no observable difference between being in Zero G and perpetually falling, at least from the perspective of the astronauts.

A microgravity environment is a special case of a zero G environment where the allowed accelerations can be measured in micro G's. Zero G doesn't mean precisely zero acceleration. Second, zero G does not mean zero gravitational field. Even if we ignore the Earth's gravitational field, anything in orbit would experience gravitation fields from the Sun, Moon, and any other object visible in the universe. If my calculations are co

      Since you're being a nitpick: they're not in "zero g", they're in orbit. There is a difference. One means there are no (or, in practical terms, very little) gravitational forces acting on you; the other means you're hurtling through space fast enough that you counteract gravitational forces trying to pull you down to the planet.

      Yes, they could (although, personally, explosive bolts and electromagnetically-held ROOMS of equipment would not be on any spaceship I would ever fly on... just imagine the potential for going wrong!)

      But, it'll probably take a handful of man-hours and, to be honest, space agencies have trouble finding astronauts enough stuff to do to keep them busy anyway especially on "space stations" as opposed to shuttles, orbits, missions etc. Plus, you'd have to manually check everything at some point anyway - might as well be while you're "unpacking" your new space-station room (remember to keep the box it came in in case you have to send it back!).

      Plus, one bolt in the wrong place, coming loose or not coming off nicely and you're in deep trouble and hardly able to pop down the local DIY store to pick up a replacement.

      Astronaut missions are always rigourously scheduled and planned. You'll probably find these people have an actual list of every bolt to be taken off in what order with what tool and what to check before and after every one. Similarly, when "just" tightening a bolt, they would have data on torque, etc. which they would follow to the letter.

          I happened to listen to live activity today. The pilot, a shuttle first-timer, kept asking if the stop-go incrementing counter on the fuel-cell monitoring software was awry - he wouldn't let it go, even after Houston told him they had spent enough time on what was obviously a non-issue and to move on. He kept making suggestions and they waited patiently as he chatted and rambled. It was clear they were giving into his first-time fever, just to placate him, but still, talk about a time-waster.

          In addition, being as the shuttle commander and ISS in-charge are both women, making for yet another space first (?), the two were so enamored with the idea, they miscalculated the time before the big public TV presentation of the new 'Harmony' module, thinking they didn't have time to spruce their hair for the cameras - Houston calmly told them no issue, the circulation fans had been adjusted from the ground to keep everything on schedule - plenty of time.

          The shuttle commandette told the ground-control guy "thanks for having our back on that one!" ...ground control was in control - not the nitrogen-breathing, image conscious, time wasting, hubris-fevered staff-monkeys in the air.

            The current maintenance load for the ISS is about 2.5 people. [nap.edu] The Soyuz capsule used for emergency crew return limits the ISS population to 3, except when another spacecraft is docked. So most of the crew time is tied up just keeping the thing working. The original concept was to have a permanent crew of 6, maybe more, and a "crew return vehicle", but that was abandoned around 2002.

            • The science load has increased over the past few years (not just overall science, but the stuff the astronauts are doing directly). I suspect that they've managed to lower the construction and maintenance load a bit and have been able to redirect some of the excess time to science projects. So maybe they still need 2.5 people, but those 2.5 people don't need to work as much.

                • 14:30-15:34 - ESA astronaut and ISS Flight Engineer no. 2 Thomas Reiter, together with his two colleagues, American astronaut and ISS Commander Michael Lopez-Alegria and Russian cosmonaut and ISS Flight Engineer no. 1 Mikhail Tyurin, will be woken up at 14:30. This time will be dedicated to the Station inspection, the morning toilet and breakfast.

                • 15:34-15:49 - Reiter will carry out a radio contact with the AMATEUR RADIO ON ISS (ARISS) equipment. ARISS, is an international working group of volunteering amateur radio operators specialised in satellite telecommunications, aimed at building, developing and maintaining the amateur radio activity, using the radio station on board the ISS. During this session the ESA astronaut will execute a live radio contact with the winning classes of the ESA/DLR competition "Ich will's wISSen" at the Landesmuseum für Technik und Arbeit in Mannheim, Germany.

                • 15:49-16:15 - Thomas Reiter will have this time to complete his morning post-sleep activities.

                • 16:15-19:30 - Following an unallocated period of time, Reiter will exercise for a period of 90 minutes on the Resistive Exercise Device (RED), which is located in the 'ceiling' of Node 1. The exercise equipment is made up of resistance chords, which allow crew members to exercise and tone various muscles in the legs and in the upper body. The resistance can be set in increments of 2.3 kg up to a maximum of the force equivalent to lifting on Earth a mass of 195 kg.

                • 19:30-21:30 - The ISS crew will participate in a two-hour review with specialists on the ground to discuss issues related to the on-board timeline of upcoming activities.

                • 21:30-22:30 - The Expedition 14 crew will meet in the Russian Zvezda module for a one-hour midday meal.

                • 22:30-23:30 - Reiter will install a remote sensing unit, which has a small transmitter antenna to radio measurements to a Space Station laptop computer for recording on a PMCIA card to be downlinked later to the ground. The remote sensing unit forms part of the internal wireless instrumentation system (IWIS), which records structural dynamics of the station. The IWIS utilizes sets of accelerometers and strain gauges, which are supported by a network control unit and their own remote sensing units.

                • 23:30-00:10 - Following a period of unallocated time, Reiter and his ISS colleagues will participate in a 20-minute conference with ISS programme managers on the ground.

                • 00:10-00:40 - Thomas Reiter will perform 30 minutes of routine maintenance on the Russian Zvezda life support system.
