Lockheed Martin Wins Contract to Build Mars Lander

Lord_Slepnir writes "Lockheed Martin has won a contract to build the Orion crew exploration vehicle that will eventually take humans to the moon and then on to Mars. This vehicle will hopefully also replace the aging space shuttle fleet. According to NASA the vehicle will have manned missions by 2014 and moon missions by no later by 2020."

We can aerobrake to slow down a 2t probe from Mach 20 (I'm not sure the entry speed of the probes, this is just a guess. I don't think it will be slower than that) to Mach 1.0 in Mar's atmosphere. That's what MER and pathfinder have shown us. But to slow down a 200t spacecraft from that speed to Mach 1.0 is much more difficult. There is simply not enough air in the Mars atmosphere, especially in the upper atmosphere, which is where aerobraking takes place.

      Reverse rocket propulsion has worked on moon, but in order to do it on Mars, we need a whole lot more fuel. IIRC it's on the order of 5X the mass of your payload. The reverse propulsion problem is also compounded by the strong side wind.

      As for wind strength, I was not referring to the surface storm on Mars, although it's another factor (Mars has the worst dust storm in the solar system). When the spacecraft is trying to land, the parabolic trajectory dictates that you will get sidewinds with respect to the vertical axis of the spacecraft. It makes the rocket a LOT harder to control.

Taking values from this NASA Web site, the terminal velocity for a 200-tonne object with a 100 m^2 cross-section (a heavy space shuttle) is still above 1 km/s at 5000 m altitude.

      Well, carbon fiber is a mixed bag. It's not leaps and bounds better than lithium aluminum, but it is a better material in most respects. On the other hand, it's more expensive to fabricate structures, especially large structures, out of carbon fibre. Thus, you're losing out on the price advantage in exchange for getting slightly better performance.

      We already had some impressive carbon materials in the 60s, like carbon-carbon. They're cheaper now, but not that much cheaper. The problem is fabrication: you have to make a mold, you have to get your polyacrylate cloth into the mold, and you either have to bake it with epoxy or continually provide pressurized, high temperature gas over a period of days to weeks (depending on whether you're making carbon fibre or RCC). It's an expensive, failure-prone process. Heck, we're just now starting to see carbon fibre airlines (the Dreamliner).

      In short, yes, some rockets have flown with carbon fibre tanks (not even counting posers like SpaceShipOne), and it's a great material, but it's not a be-all, end-all. It overall works out to one of those incremental improvements.

      Now, if we could mass produce cubane, that would pretty quickly provide a "leaps and bounds" improvement. The same goes for rapid CVD of high-strength carbon compounds (diamond, nanotube composites, etc). Other things include alternative propulsion methods (say, NERVA style), if you can pull them off. But beyond this, we're kind of limited to incremental improvements. There are a *lot* of potential incremental improvements out there, but they'll take time.

      Everyone on earth absorbs some radiation constantly. Pilots who fly polar routes regularly and people who live in high altitudes receive double or more the amount of radiation that regular people do.

      In interplanetary space astronauts would receive more radiation, but they would not receive enough radiation to make them sick by a long shot. It is estimated that a two and a half year Mars mission would expose an astronaut to an accumulated 50 rem of radiation. This only increases a person's chances of dying of cancer slightly, about 1% over thirty years. Over thirty years a nonsmoker adult of middle age would have a 20% chance of dying of cancer. Add 50 rem of radiation and the chance of dying of cancer is roughly 21% instead of 20%. Even if the radiation were 100 rem the chance would only increase by 2% to 22%.


      Also, the design of the spacecraft and habitat/home on Mars can reduce exposure to radiation. Put sandbags on the roof of the house on Mars for example. On the spacecraft put the water and fuel around the edge of the craft forming a thicker wall.

      Radiation would not stop a manned mission to Mars.

      This is enough to give 10% of men and 17% of women aged between 25 and 34 lethal cancers later in their lives

      1 sievert = 100 rem in radiation. So this article is saying 226 rem, whereas The Case for Mars says about 50 rem. At least the two sources are in the same ball park. The fatal cancer risk cited as 10% for men and 17% women of a young age. Because of the increased cancer risk one would probably not send women at least not on the first trip. Also, I find it unlikely that NASA or whomever is going to send a bunch of 20 somethings for the first trip to Mars. The candidates will probably be in their later 30s or 40s and that reduced the lifetime cancer risk substantially.

      The Case for Mars noted a little under a 1% increase in fatal cancer risk over 30 years for a 50 rem exposure.

      Assume a 40 year male old (life expectancy of about 80) is sent to Mars for a 2.4 year mission. Using the New Scientist's higher radiation figures that 40 year old will be exposed to pretty close to 200 rem. The increased risk of fatal cancer in the 40 year old's lifetime is going to be 4% or 5%. While this is not ideal, it really is not a showstopper for a first trip to Mars.

      In some ways it is better than the shuttle. For one, the design concept (cargo and especially re-entry shield as far away as possible from the explosive stuff and things that fall off) is inherently safer. It is more versatile in that it's mass and re-entry concept does not limit it to low earth orbit. It is thermally a better overall re-entry design. Even the landing is simpler, although it may not seem so at first review (the shuttle has only 2 or 3 landing options and it comes in really fast).

      And there are ways that it's inferior. It can't return a large cargo to earth. It can't support major missions on it's own (like Columbia's last mission, where it carried a pressurized science module with over 100 experiments). It can't serve as nearly as effective work platform (think Hubble repair), lacking an airlock and that cool robotic arm. It will only look pretty darn awesome instead of freaking, amazingly awesome when taking off and landing. Etc.

      The point that I really want to make with this post is that we are still number 1, although I wish we had needed to work twice as hard to maintain the lead we have over anybody else. Instead Russia, the historic embarrasser of riches, is hanging onto the success of their Soyuz design and doing almost nothing else. Off the top of my head I can't think of a mission not related to the ISS in years, aside from commercial launches. China is talking big, but at this point has launched 3 people on two manned missions and has an unmanned lunar mission in the works. Europe as a whole is looking good, with several major ISS modules to their credit, the Mars and Venus Express probes plus a few smaller missions like SMART-1, and a healthy commercial market, but no real ambitions for growth. Japan has stayed on the down low, catching headlines for the ill-fated but ambitious missions to an asteroid and Mars, but backing away from their original intent to contribute a laboratory module to the ISS. Only the EU and Russia have together proposed a new manned spacecraft, the Klipper, but have not yet committed any real money to it.

      In the meantime, the US has continued to carry the bulk of the ISS (although as much due to our own desire to as to any other partner's avoidance of it). The shuttle has successfully returned to flight. Its replacement is well underway. Unless I'm forgetting something, with Hubble, Chandra, SOHO, and Spitzer we're the only nation managing major space-based observatories. We have probes on their way to Mercury (Messenger) and Pluto (New Horizons), a fantastic probe returning tons of data on Saturn (Cassini), and three orbiters around Mars. Then there's those indominatable rovers, which have been operating for over 10 times as long as their design goal and are soon to be joined by the Phoenix Polar Lander, followed by the impressive Mars Surface Laboratory in 2009. Don't forget Deep Impact or Stardust either, the former of which looked inside one comet, while the latter collected samples from another. As far as the moon goes, the Lunar Reconnaisance Orbiter will launch in 2008 with follow-ons to be designed based on research over the next five years.

    The title of this story is wrong -- Lockheed Martin just won the contract for the Orion Crew & Service Module (CSM). The CSM is the party which will transport astronauts around in space, and land them back on Earth. The actual lunar lander, the Lunar Surface Access Module (LSAM), hasn't had its contract awarded yet, to say nothing of a "Mars Lander."

    Of course, all this is rather confusing. I follow space news more closely than most, and I often get confused myself. Fortunately, Wikipedia's article on Project Constellation (the overall architecture) has a nice overview of what all the pieces are and how they fit together.

    That said, I really wish that NASA would spend this money on the Commercial Orbital Transportation Systems program instead, accomplishing the same objectives in a more cost-effective manner. With COTS, companies only get paid if they succeed. NASA will instead be spending $3.9 billion (assuming there aren't cost overruns) just to get a capsule, while giving a total of $500 million (split between 2 companies) to COTS in order to get both rockets and capsules. To top it off, the COTS vehicles are scheduled to be completed years before the Lockheed Martin capsule is ready.

      You are articulating many of the misconceptions about COTS that have been brought up recently in the space news. First off, it is completely unfair to compare COTS with CEV. CEV is being designed to support lunar and Mars missions. The delta-V, life support, habitable volume and TPS requirements are not even comparable to those for the COTS missions. Also, the $500M is only for a demonstration of cargo transportation capability - the crew transportation demonstration will not commence until one of the particpants has demonstrated pressurized cargo deliver and return and will be funded seperately

      Second, COTS was underfunded on purpose. NASA wants out of the space transportation buisness and instead wants to be able to allocate its resources toward exploration while paying commercial providers for cheap, safe, reliable access to LEO. The problem is that there is no provider for such services. The goals of COTS is to facilitate the creation of a market for commercial space transportation and to then call upon these services to meet our ISS crew and cargo requirements. Completely funding one of these ventures would be "buisness as usual" - just with a different upstart partner. By only partially funding them, NASA is effectively forcing them to have a strong financing plan. Investors and venture capitalists will only put their dollars into companies with strong buisness plans - presumably ones that:

      • have potential for growth (read: aren't reliant on NASA)
      • turn a profit
      If NASA can jump-start such a space transporation market with this COTS seed money, then they will be but one of many customers in a growing market (of both customers and providers). Bigger market - more missions - more payloads and research on orbit - cheaper cost/kg. Science wins, industry wins, NASA wins, the taxpayers win.

      In the early part of the last century, the postal service played a similiar role in creating the aviation infrastructure necessary to eventually support a commercial air transportation service market.

Did you read the mentioned whitepaper? NASA is pushing for CEV block 1 to be the Shuttle's replacement for personnel transportation to the ISS, and seeks to "minimize the gap" between Shuttle retirement and CEV qualification. This leads to short-term decisions, such as deleting methane-LOX engines (much better in the long term but too far off for ISS) or requiring the capability to use older-style docking equipment (because the ISS does not have a newer-style docking port).

      This is the agency that killed the EELV-based CEV schemes. Remember, its predecessor, the OSP, was supposed to be light enough to be launched by heavy versions (or maybe even medium versions) of the Delta 4 and the Atlas 5. When it was clear that the Shuttle would be retired, they switched to a heavier CEV which needed a Shuttle-derived heavier launcher. This looks like a jobs program to me.

      There also is the argument that man-rating the EELVs would be more difficult than starting from scratch. Yet, first, NASA did not make clear what would be required for man-rating a launcher; second, the Shuttle itself is not man-rated and less reliable than the Atlas family; third, the Ares I and V turn out not to be Shuttle-derived after all: new SRBs (5-segment), new ET (10-meter tank, incompatible with current tooling), new engines (RS-68 not man-rated, after all, and the J-2 has not been used for decades).

      Yeah that cold environment would be the coolant.
      http://en.wikipedia.org/wiki/Coolant Take a look there.

      Coolant is not cold. Get that fact memorized. Coolant is what you use to make something else cold. Hence the more technical term "heat transfer fluid".

      On Venus, coolant would have to be superheated to a temperature greater than the Venusian air by compression, then cooled to terrestrial temperatures by expansion in order to cool a habitat. This isn't even remotely possible with modern heat pump technology. It may never be possible. The laws of thermodynamics aren't breakable, so even if we could provide a fluid that had the properties we need, the energy requirements involved in initiating that kind of temperature change will be enourmous.

      Hell if all else fails set up a series of highly insulated chambers to funnel your hot material through.
      Also doesn't work. You want your heat sink to be conductive, not insulated. Remember that a heat sink heats up over time, so you'll want to let it dissipate if you plan on using it continously. An ideal heat sink is a deep pool of cold water exposed to open air, which is easy to find on Earth, but a wee bit difficult to swing on Venus.

      This is not an insurmountable engineering challenge, although it is a large one.
      Actually, it is insurmoutable using modern technology, and I don't share your optimism about what we'll have available in the future. Some limits have nothing to do with technology and everything to do with the laws of physics (in this case, thermodynamics)

      Heyyy, wow did you ask the wrong man. Here's an older post I made....

      With all the talk lately about a space elevator, I got to thinking after a recent slashdot discussion, just what advantages would a space elevator offer over a tower launch? I contacted the man responsible for a similar idea, the skyramp (warning: hideous javascript menu may break firefox), Carlton Meyer, and had a dialogue in which he pointed me to a tower launch archive.

      The ideas I see bandied about there are similar to what I had in mind, which would be essentially an 11km tall tower (think pylons rather than skyscrapers, based at sea), with evacuated airless launch tubes, using nuclear reactors to power a maglev or pulley system to accelerate vessels to escape velocity. These would then emerge above the end of the troposphere, with it's associated weather and air pressure, and have little to no fuel needed to escape the earth's gravity, meaning you could do a lot more while you were up there. At normal launch accelerations you can get to LEO with very little external propulsion.

      Not only would this enable multiple launches daily, it is, unlike the space elevator, readily achievable with today's technology, and financially viable as well. Given NASA had an annual budget of $16.2 billion for 2005, and a nuclear power plant costs a cool billion to build, give or take, we could have this up and running in a few years.

      Space has got vast, essentially unlimited resources. One recent story pointed out the trillion dollar iron asteroid up there. The thing has about 5 tons of steel for every man, woman and child on earth. And thats just one of god knows how many... billions more?

      Once we leap the cost to escape hurdle (as I think I have managed), we can proceed to use these resources. There are several obstacles in the way of this, first of which is zero gee mining, we have no idea how to do it. We can either mine the ore out there, or bring the asteroid back into orbit and slice it up there. Or slice it up and send it back to orbit. I would be opposed to moving it back into orbit for processing, purely for the debris issue. Perhaps a lunar base would have some merit there.

      So we set up a mining and processing operation either on the moon or in deep orbit, and start cutting and processing one of those bad boys. Whats the first thing we build?

Lofting one planetologist on a one way flight to Mars with some lab equipment and a small set of hand tools recognizable to a geologist or rock hound on Earth would probably yield more data than all of the robotic Mars probes we have, or could ever, get to Mars.

      On Earth, that's very true. In space, people are a poor substitute for robots. People require pressurized cabins, oxygen, water, food, exercise, entertainment, and so on... and worst of all, they aren't considered expendable, so every mission has to be a round trip (you personally may disagree with that, but it's the political reality nevertheless). That means that including humans as part of the equipment drives up the cost by three or four orders of magnitude. Sure, it increases the benefits as well, but not by anywhere near amount needed to justify the expense.

      It doesn't really matter how cool or useful it might be to have a human on Mars... if it's not practical, it won't happen. And for the forseeable future, it's not practical. If you want it to become practical, then the problem you need to solve is how to economically launch tons of material into orbit. Once we can routinely lift hundreds of tons of supplies into orbit, then it will be possible to build spacecraft large enough to support manned trips to Mars. Until then, robots are the way to go, simply because only they and their support gear are light enough to lift to orbit.

    The only way out of this dilemma is to look for phenomenon that goes beyond our current understanding of physics. One possibility is the new model (of physics) developed by Burkhard Heim. He postulated additional dimensions beyond the 4 known ones: 3 spatial dimensions plus time. Using these additional dimensions, he rewrote general relativity in a quantum framework.

    From this model, Heim developed a theory that enabled physicists to accurately calculate the masses of the fundamental particles. Unfortunately, this theory is the only part (of his work) that has been peer-reviewed in a journal.

    Is the rest of his theory true? If it is true, it would have incredible ramifications. It means that we can build a hyperdrive to power a spacecraft to mars in about 3 hours. The hyperdrive would shove the spacecraft into a strange place which is outside of our standard universe of 4 dimensions; in that strange place, the speed of light is much faster than that in our universe. The hyperdrive would then push the spacecraft along one of those additional dimensions (beyond the basic 4 dimensions), powering the spacecraft towards Mars along that other worldly dimension.
