Lockheed Gets $485M From NASA To Create MAVEN Craft

coondoggie writes to tell us that Lockheed Martin has landed a $485 million contract to create the spacecraft for NASA's MAVEN (Mars Atmosphere and Volatile EvolutioN) project. "MAVEN is the second mission in NASA's Mars Scout Program — a series of small, low-cost, principal investigator-led missions to the Red Planet, NASA said. The Phoenix Mars Lander was the first mission under the program. Lockheed Martin is the industry partner on the Phoenix mission. It designed and built the spacecraft, and also provided flight operations and currently surface operations for the lander. The mission has been extended through Sept. 30, 2008."

    The R100 plan is ideal for exactly those sorts of conditions. The original actually did fly through some really nasty storms - quite possibly 60mph or worse - and modern materials and building techniques should provide vastly superior structural strength. The superior shape to modern blimps means you should be able to fly directly into 60mph winds, as you have a far and away lower profile. For the same reason, side winds should be much less of a threat. However, the R100 is usually also described as much stronger and lighter than the Zeppelins (which were tough enough to pose a serious threat to the RAF), suggesting that even the whirlwinds that crop up should not be a serious threat. If you can survive high-speed machine-gun bullets, you can probably survive a sandstorm - at least, so long as you're high up enough to avoid the worst.

    You might be right about that, but I find fault in the logic that we shouldn't fund NASA because they didn't do much during the last 40 years. You complain about stupid wars, but what they experienced in 1969 was the culmination of an effort to win the mother of "stupid wars". Whether the Russians or Communists were significant or not is up for debate, but the Cold, Korean, and Vietnam Wars were all unnecessary pissing contests and as a result of that American piss made it to the Moon.

Since then --- technology has advanced, discoveries have been made, and science has caught up to the engineering accomplishment of putting a man on the moon. By suggesting that NASA be defunded, you are suggesting that everything during the last 40 years has been a waste.

Do you recall the challenges of Skylab in the early 70s when NASA had a pair of booster rockets that it needed something to do with? This was a far cry from what ISS is today. So, I would argue that the past 40 years have been instrumental towards getting us to where are today... which is in the position to *consider* a trip to Mars 20 years from now. However, without the groundwork that this and other missions have laid, it will never happen. Because the most important thing for a human Mars mission is that he (or she) doesn't die there. I have no doubt that any attempts in the 80s or 90s to customize a Saturn V with a crew vehicle destined for Mars would have resulted in such a death. In 20 years, though, I think technology exists that will enable such an astronaut to survive.

    If the R101 is in any shape to support anything, it's the ground. Obviously, with the R100 design, you'd need a much larger volume (but hydrogen is still vastly lighter than the CO2 of Martian air), a much lower mass (the R100 was designed to support a large human crew, aviation fuel and gigantic engines, and had a frame made of steel and aluminium as I recall, whereas a UAV version for unmanned Martian missions needs a few tens of pounds of payload, solar panels and a few light electric motors, and a frame of carbon fibre with airgel struts should be solid enough for such purposes). The R100 was also much much lighter than Terran air. It supported its own weight, but at significant (for the time) altitude. Notice I'm talking about an airship that actually IS comparable in size to the R100, not something scaled down the way the payload is. Nothing, when compressed, doesn't take up much space, and the lower air pressure of Mars means that the air bags would be filled with mostly nothing. All you need to store is the hydrogen gas under pressure. As per the Archimedes Diver, the relative pressure in the airship can be used to control altitude, so long as the containment is adequate. For those familiar with the device, it is clear you don't NEED to shed the gas used for buoyancy so long as pressure is controllable. In consequence, you only need to ship enough to inflate the device, you don't need to ship any for re-inflating later. Other factors include temperature. So long as the relative temperature of the hydrogen is high, you get extra volume and therefore extra buoyancy. (You only need to displace the airship's mass to float, and displacing more is what makes you rise until the relative air pressure means you are only displacing an equal amount. Which is how you can tell that anything that can handle 20,000 or so feet above mean sea level must be far lighter than the air displaced at ground level and not just supporting its own weight (which implies a ground level measurement). A black surface (that ultra-black stuff reported on Slashdot not too long ago, for example) should be handy for that, as would any heating elements. Not much risk of fire if there's not much oxygen, so frankly you might as well push such a design to the limits of the material. And that's the key thing. The material. You need gas bags - basically floatation bladders no different from those in fish - that can swell sufficiently to allow maximum altitude but be strong enough to support Archimedian descent through pressure rather than through deflation. The latter requirement also takes care of surviving the storms, as any material strong enough to handle the pressure from the inside is strong enough to handle the buffeting from the outside. And, yes, you would need a huge airship to support even a small mass, due to the lower air pressures involved. But, frankly, that's the only engineering problem I can see. The rest was mastered by humans a century ago and by evolution two billion years ago.

    The ships can simultaneously be stealthy and attractive. One example: every navy has standards and many have differentiation in appearances due to national and architectural and service input. Anyway, while i am happy th SK navy and the JMSDF have formidable ships, i wish the SK would effectively or economically find a way to to suck up or give in to political reasons resulting in the King Sejong The Great looking like another Burke clone. SK can do BETTER than THAT. Atago is sexier than DDG-8+.

    Galileo lost a huge amount of data because its high-gain antenna was never usable, considerably reducing the return on the more than $1 billion invested in it. Mars Observer was simply lost, $800 million down the drain. When you put all of your eggs into one probe, a single mistake destroys an enormous amount. Using more, smaller probes reduces the risks and ultimately either costs the same or saves money. A gain in flexibility is just a bonus.
