Panel Advises Longer Life For Space Station

suraj.sun writes "A presidential panel reviewing the US space program has found that the United States needs to boost NASA's budget by $1.5 billion to fly the last seven shuttle missions and should extend International Space Station operations through 2020. The panel also proposed adding an extra, eighth shuttle flight to help keep the station supplied and narrow an expected 5-7 year gap between the time the shuttle fleet is retired and a new US spaceship is ready to fly."

    The Shuttle/ISS subcommittee headed by Dr Sally Ride has presented three options:

    1. Do nothing, let the shuttle stop flying at the end of 2010 and let the station be de-orbited at the end of 2016.
    2. Fly 1 more mission, and still de-orbit the station at the end of 2016.
    3. Extend station operations through to the end of 2020 and fly more shuttle missions to support it.

    The options explain how to do it, what funding will be required, and the consequences on other programs.

    The President and the new NASA Administrator will take these options and decide which to implement, depending on what funding they can get from Congress.

    The committee is not chartered with making any recommendations, and the options are not final until the report is released, around Aug 31.

      You're overstating the Shuttle's reboost utility for the station. Of all of the Shuttle's RCS thrusters it can only use its venier thrusters for reboost maneuvers. It's primary thrusters' plumes are directed at the station while docked and could damage it during a long turn (which reboosts require). Even using the smaller venier thrusters the burn has to be timed and pulsed carefully to keep from over stressing the docking adapters on both the station and the Shuttle. When the Shuttle is docked its only point of contact is the docking adapter. Most typically a docked Progress provides reboost for the station.

      The issue during the Columbia stand down was MPLM missions that had been scheduled were put on hold. The MPLMs can carry about 10t of cargo so there was a huge gap in the ISS supply chain. The Progress can only carry about 2.6t of cargo which meant a single scrapped MPLM Shuttle mission would have required four previously unscheduled Progress flights. At the station complete stage the Shuttle will be less of a resupply necessity since the station will have water recycling (it has that now) and all of its modules will be in place. The ISS was designed to only really require ATV/HTV/Progress resupply once it was fully armed and operational. The Shuttle was required for construction but much less so once the station is actually complete.

That could be done, and ion engines are being used with the Dawn spacecraft currently enroute to Vesta (an asteroid), but it is something that would take a bit of an effort to build such an engine in the first place.

The most significant issue is the life-support equipment, which is also something that most "megastructures" don't have to contend with here on the Earth... or have to deal with entire environment systems like liquid waste recycling. Imagine if a mall had to not only deal with the toilets, but it also had to have the sewage treatment plant and water reclamation system to put water into the drinking fountains.... it would cost a whole lot more money to operate and maintain those buildings. Those are also things that enjoy economies of scale as well, where a larger station/building can be more efficient in its resource consumption while a small building like a single-family home must depend on a much larger urban infrastructure for its needs.

Explicitly for the ISS, there have been the Multi-Purpose Logistics Modules designed by the Italian government and flown on the Space Shuttle named for Italian scientists (and for NASA the Teen-Age Mutant Ninja Turtles) Leonardo, Raffaello, and Donatello. These were modules that were docked to the ISS, and on occasion have been swapped out and had the modules brought back to the Earth in the shuttle.... essentially using the Space Shuttle as a trash hauler. Yes, there have been some scientific research products that have been brought back to the Earth in these modules, and broken down research racks and other items that have value in and of themselves for research purposes, but a great deal of what was stuffed in these modules for shipment back to the ground included things like old clothing, used food trays, paperwork for projects that have been completed (like checklists and installation manuals), and packaging materials for all of the equipment that has been installed.

      In addition to these modules that have been returned to the Earth on several occasions, there have been several satellites which have been captured and stowed into the shuttle cargo bay as well... including one satellite where NASA got a check from Lloyds of London for ship salvage when the satellite was repaired and sent back up into space on a later mission and redeployed.

      Another research experiment using the down-mass haulage capability was a research project that tested how various metals and materials functioned in a Low-Earth Orbit environment for an extended period of time (it was in space for about 10 years) which was put into space by one shuttle mission and it was retrieved a decade later by a subsequent mission. Simply put, this was one research project that simply could not have been done at all without the down-mass capability of the shuttle.

      All this said, and in spite of having the Shuttle being used for this unique capability that no other spacecraft possesses, it is not used nearly as often as it could be nor is the loss of this capability mentioned in design analysis of proposed vehicles in the future. Only the Shuttle can take large and bulky items as large as a semi-truck trailer (aka as big as the Hubble Telescope) and bring those items safely back to the ground without those items requiring a re-entry system of their own.

      Any little bit of acceleration would help, and one of the things that the ISS has is a whole lot of energy being produced in its solar cell array. There is about 50-100 kilowatts (solar array modules have been added since this article) of power available for running experiments and performing tasks above and beyond maintaining life support and other critical station functions like radio communications and other mechanical systems critical to station operations.

There are things you can also do with a huge mass of materials like are found with the ISS and reprocess that stuff now that the effort to get it out of the Earth's atmosphere has happened which would have value all to itself, but I digress.

      In terms of the ion engines themselves, the maintenance costs involved aren't nearly what you think they are. Of the various ion engines that have already been deployed into space and are currently operating (like the Dawn spacecraft) they are designed to operate for decades without having human assistance in terms of repairs or even refueling. All it really needs is a supply of electricity... of which the ISS has in ample quantities.

      For something that has cost taxpayers on the order of $200 billion to put up into space in the first place, spending a couple more billion to keep the thing from deorbiting would certainly be worth the effort to design, build, and send up into space. Ion engines, while there is certainly ongoing research to try and get them to be improved, have become a proven technology and something which has actual flight experience. To dismiss this as some speculative future technology is to deny the production equipment that has already been produced.

      If installing an ion engine on the ISS could eliminate even one shuttle resupply flight, that by itself might be more than enough in terms of costs to justify the added expense of developing an ion engine that would work with the ISS as well. Once installed, the ion engine could work for a decade or longer without having to be refueled.

      BTW, the Progress vehicles, which they can and do provide propellant and thrust for station keeping on the ISS, is not sufficient to maintain the altitude that the ISS operates at. I suppose that a dedicated Progress mission that is nothing but fuel could do the job, but that is also quite expensive and could be potentially catestrophic. It was a Progress resupply flight on the MIR where the docking procedure missed a step and the vehicle crashed into the station... causing considerable damage. Eliminating even a couple resupply flights to avoid damaging the ISS might also provide justification and rationale for adding something like an ion engine as well.

      As for why the ISS isn't providing scientific research on the scale that would be considered useful, that is as much a political issue as it is a technical issue: NASA canceled modules like the Trans-Hab module that would have provided the logistical and life support equipment necessary for housing researchers in sufficient quantities to make the ISS work. The ISS was designed for a minimal crew of at least a couple of full-time astronauts to perform maintenance, and was originally supposed to have at least three to four full-time researchers (or the equivalent) operating the research equipment. The space to house those astronauts simply never got put up, nor have the vehicles to support larger crews on the ISS such as the Crew Return Vehicle that would have supported emergency evacuation of the ISS ever been built.

This was a slight degradation of the solar panels and their overall efficiency, not a dramatic drop in their overall power ability.

      What caused the jamming was that one of the bearings in the positioning mechanism for the solar arrays literally welded itself onto the motor and caused the array to grind to a halt. This is BTW one of the nasty engineering issues in space, where pieces of metal like to come together and stick to each other when in a vacuum.

Although it's likely to be quite a bit more reliable (e.g. safer) to fly, the Constellation program doesn't do much to increase access to space. Constellation re-uses the Apollo/Shuttle launch infrastructure, with only two launch pads and two (or possibly 3, there is an unfunded plan to build one more) crawlers, and the constraints of the Vertical Assembly Building (with a limited number of assembly bays, one of which is used for storage of rocket parts). This means the flight rate to orbit tops out at something like a dozen or 18 launches a year, maximum. Flight rates for the heavy lift Aeries V are likely to be so low that the vehicle will never achieve a reasonable per-flight cost, because too few vehicles will be built to get the cost of flight hardware down.

    NASA has abandoned the goal of building a reliable, cheaper transportation system. They were hot on the trail with the X-33 / VentureStar program. Like nearly all R&D programs, it went over the original budget and behind schedule. However, the program had the right goals, and the right basic plan for getting to them. If NASA had stayed on course, we would have had a replacement for the Shuttle by now. The planned VentureStar production flight vehicles would be flexible enough to sustain the ISS. It would have a capacity high enough (in terms of payload per flight, which was similar to the Shuttle) and flights per year (which could scale with the addition of vehicles, without the constraints of the expensive and limited Apollo-era launch systems). The modernized vehicle design (lifting body airframe, engines with fewer moving parts, substantially more durable thermal protection system, simplified container-paradigm-based payload integration) would yield shorter turn-around of a single vehicle, from days to a couple weeks, compared to a few months to several months for the Shuttle).

    Instead, NASA dabbles in scramjets, with a million here and a million there in loose change. Scramjets are a technology with great potential, but even if aggressively funded (which they are not) they won't be ready for a long, long time. A more modest program like the X-33 / VentureStar could get us to higher flight rates with Shuttle-like capacity and reduction in cost of payload delivery which would be substantial enough to stimulate the space economy. We could get to the Moon and Mars a lot cheaper, and go there more often with a rational approach to building a transportation system. (NASA needs to rethink the in-space transfer vehicles, too. VASIMR is a technology within our reach, and if developed as the inter-planetary engine, can dramatically reduce flight times to Mars, from many months to 1 month.)

Part of that cost is the sunk cost of the car itself, and also make a VERY big assumption on how long that car will be kept in service, or more exactly how many miles it will be driven. That's not a good assumption, unless you've worked out the math for yourself and know how long you plan to keep your car.

For people like us, the cost per mile is only barely more than the cost of gas + tires.

How much should we charge the XYZ satellite program for a repair mission? Those are questions where you start from average cost.

A sort of mineral sponge, zeolites have the ability to absorb and release liquids and gases such as petroleum or hydrogen while remaining as hard as rock.

    ...

    Results from the samples mixed on ISS suggest that the Lewis acid catalytic sites are altered in microgravity, as indicated by lower catalytic activity in the MPV probe reaction compared to Earth-grown zeolite. This further suggests that the control of fluid dynamics during crystallization may be important in making better industrial catalysts. Although space-grown zeolites had the same particle morphology and identical surface framework as zeolites grown on Earth, the average zeolite size of the space-grown crystals was 10% larger than crystals grown on Earth (Akata et al. 2004).

    Larger zeolite crystals allow researchers to better define the structure and understand how they work, with a goal of producing improved crystals on Earth. Improved zeolites may have applications in storing hydrogen fuel, reduction of hazardous byproducts from chemical processing, and more efficient techniques for petroleum processing.

Still, the trick is to find the energy to get the ISS to that position rather than keeping it in low-earth orbit.

    We need a space station that can be used for construction, even if it is only rudimentary, so we can start building the infrastructure necessary to use space travel for more than photo ops.

    So you want to build a construction station that is capable of building more infrastructure. What do you mean by this? Is it going to build spaceships or more space stations that can build even more space stations? Do you know what you are talking about?

    Constant small thrust could push it up

    For example, if the Russians threw up a Topaz-2 reactor and a couple spools of copper wire, and unspooled them toward the Earth to cross the Earths magnetic field lines, by pumping energy down the wire they could raise the orbit no problem. We considered a couple spools of copper wire as a means of powering space stations, at the cost of increasing orbital drag, but you could easily run the generator in reverse as a motor, so long as you had enough power to overcome atmospheric drag.

    And just as importantly, what experiments have been done up there that were not possible with robotics.

    A fair bit more than you realize. The main advantage of having a human researcher is that you can improvise an experiment and make changes on the spot that you can't do with a robotic mission. The iteration of the research cycle can be done in days or even minutes if you have a human researcher, where as with a robotic device each cycle will take years or decades from when you get results to sending up another package to test a new hypothesis.

    This isn't to say that robotic exploration of space is moot and shouldn't be done (on the contrary) but that a complete and total dismissal of manned spaceflight is equally as illogical. Both have value, and getting people into space has more value in and of itself as well.

    The point of the grandparent post was that such scientific research.... which has happened and has appeared in peer-reviewed scientific journals of various fields... is usually discussed in narrow terms and regarding specific discoveries and not trumpeted in mainstream media outlets.

    While I'm not as familiar with the ISS research as with previous manned spaceflight knowledge, there certainly has been value with manned exploration to make these critical decisions. Explicitly the research conducted by Harrison Schmidt during the Apollo 17 mission engaged in more discoveries about the Moon in particular and the Solar System in general than all of the robotic missions either there or to the rest of the planets of the Solar System combined. Yeah, that is a tall order, but if you read the scientific literature that came from that mission and the value of having a trained geologist performing a field survey in person and using his own eyes to make the determination of what samples to select.... it made a huge difference compared to the haphazard method of sending a probe there and having blind luck to find useful samples. And that is for going through the expense of getting somebody on the surface of the Moon.

    Part of the problem with the ISS is that essential parts like the Trans-Hab module (built but not flown or schedule to fly up there) that would have provided the necessary living space for additional researchers got cut out at the last moment. In theory up to a dozen people could be on the ISS, but at the moment only 3 can live on it for long periods of time, and only two can be there with only Progress resupply modules. It also takes at least two and usually three people just to maintain the equipment. The lab modules were sent up, but there isn't a place to put the researchers that would be required to fine-tune and operate the equipment in a manner that would take advantage of a human researcher.... hence the favorable comparison of research done by robotic devices. That is an unjustified viewpoint, although it is a shortfall of this particular design for the station that was designed for political and not scientific purposes.

    I think that instead of a ridiculously expensive one-off tin can that could produce "awesomely amazingly awesome" science, we should be looking toward, I don't know, the future? Perhaps making bigger and better labs in space. Perhaps building factories that could manufacture things in zero-G. Everyone is saying, "Hey! Lets build a station on the moon!" without even thinking of making it sustainable.

    The days of the tin can should have died with the Mir. The "Isn't it cool we're here?" days ended in the 70s and no ISS, moon base, or suicide mission to Mars will bring them back. It is time for NASA to mature and start looking at space travel as more than a scientist's playground.

    Science is boring.. yeah.. that's the society we live in.

    Here's an idea to make it more appealing for the majority:

    A new reality show - last ones on the station. Get 6 couples, and put them on it. Then over the length of the show, send a different couple out the airlock every other episode.

    This has the advantage of satisfying everyone's prurient interest in sex in space, and of course there could be a love triangle in which just one member of a couple meets the vacuum. In the final week, only one couple is left, but in the true tradition of scripted non-scripted reality, the station is de-orbited.

    Then the deniers can have a "We never had a space station" hoax.
