Mars Rovers Get Extra 18 Months

iamlucky13 writes "NASA has stated in the latest mission press release that funding for an additional 18 months of exploration has been approved. The rovers have breezed through 14 months of operation so far, and the money will cover expenses through September of 2006. The rovers are still operating well, and recently both experienced dramatic power boosts from their solar cells. They are no longer like new, however. Opportunity has recently experienced data loss from one of its spectrometers, while Spirit has a smudged camera lens, a heavily used rock abrasion tool, and has previously struggled with intermittent steering issues."

While the overall NASA budget is being slightly increased, the administration is also dictating which areas of research will be cut and which will be expanded. Most everything but manned space-flight is being extremely reduced.

      Many projects in which billions have already been invested are being tossed asside because NASA has been directed to return to the moon and Mars and only been given a slight budget increase (for comparison, NASA's budget was about 10% of the overall federal budget during the Apollo program). For instance, the International Space Station may be abandoned now that it has just been completed and can actually be used for (however limited) scientific purposes. As with military and economic decisions under Bush, politicians are dictating scientific decisions for political gain.

      Bush is also pushing to cut most NASA facilities not in Texas, even ones in "red state" staples Alabama and Ohio. The Texas facilities are already considered pork-barrel projects and most of the scientific work of NASA has historically been done elsewhere.

More significantly, at the heliopause, another issue arises: charge. The heliopause is where the solar wind balances out the pressure of the interstellar medium. Do the charged particles collect there, and if so, how densely? This could have profound effects for any kupier belt (or beyond) missions, as well as our models of solar system formation. Heck, we don't even know how far out the termination shock and heliopause are (and they're not in constant locations, as the sun is moving with respect to the local interstellar medium; the shape is something like a comet). Despite what we don't know about it, we do know this: the heliosphere is the source of the most powerful radio waves in our solar system - more than 10 trillion watts. By the way - it was Voyager who first detected these emissions.

      After the heliopause comes the heliosheath, which has its own set of properties which are largely unknown. It's the area where the solar-influenced material blends into the interstellar medium (and getting any data on the interstellar medium would be a great boon for astronomy)

Secondly, there are about a dozen currently achievable concepts that can do it: Orion and medusa, mini-magnetospheric propulsion, solar sail, antimatter catalyzed microfission and microfusion, the various fission core concepts, magnetohydrodynamic propulsion, and of course, my favorite: nuclear saltwater rockets. You use a water-soluable salt of a fissionable material kept in "capillaries" lined with neutron absorbers to prevent reaction until it's ready. You then pump it into a reaction chamber where it becomes critical as it is propelled out the back. It's "dirty", like pulse detonation, but like pulse detonation, most of the propelled material has enough delta-V to escape the solar system.

      One thing I'm curious about is whether black hole propulsion is possible; I've never heard anything about it before.

      Sorry, that should be "various fission core designs", in addition to the fusion core concept - thanks for catching my mistake. :) Yes, there are solid core, liquid core, and even gas/plasma core designs. Solid are the furthest along, but the least efficient.

      A number of different propulsion methods are discussed here, although it's far from a complete list.

      The problem with Orion's acceleration is that it comes in bursts. Medusa involves using a large "sail", which captures more of the explosive force. The craft is tethered to the sail, and the long tethers act as extremely efficient shock absorbers. And, since they don't need a heavy "pusher plate" and shock absorption system (or as extensive shielding), it works out to be lighter overall (despite the massive sail)

      Mini-magnetospheric propulsion involves using plasma (most sustainably, from a fusion reactor, although that's not realistic yet) to create a miniature magnetosphere around a spacecraft. The spacecraft will then repel the solar wind for a large region around the craft without having any physical structure present there, acting like a solar sail without need for a sail. Since it's smaller in mass, it should get better propulsion.

      Antimatter-catalyzed microfusion/microfission is a great concept. Pure antimatter propulsion just costs way too much, and storing that much antimatter in a reasonable-sized container is currently unrealistic. However, a single antiproton collision can release enough localized energy to start a fission or fusion reaction on its own. So, the proposed engine (which NASA has been doing some work on) involves firing tiny grains of fissionable/fusable material, and firing antimatter beams at them inside the engine. Preso - a managable fission and/or fusion reaction.

      BTW - just because one scientist says so doesn't make it true. ;) The fact remains that black holes radiate Hawking radiation, which is all you need for them to be a viable propulsive concept.

    Like much of what the Bush administration does, your claim is not really true while containing a grain of truth. While the overall NASA budget is being slightly increased, the administration is also dictating which areas of research will be cut and which will be expanded. Most everything but manned space-flight is being extremely reduced.

    Face it, if it's for Science, and doesn't give him a chance to show up in a Flight Suit, it's being cut.

  49. micro-rovers by Tablizer · · Score: 1

    * The Mars Science Laboratory will likely be pushed back to 2011 (instead of 2009), but is likely to have two or more versions constructed and sent to different areas. The base cost for a single rover is estimated at $1 billion, but another rover is expected to add $400 million. The MSL (or MSLs) will be looking for traces of organic chemicals and be further investigating the geological/climate history of Mars. The MSL is expected to weigh 600 kg including 65 kg of scientific instruments, compared to the MERs which weigh 185 kg including 5 kg of scientific instruments.

    I heard one of the reasons why they were pushed back is because they didn't want a one-shot mission. 2 rovers increases the chances that the teams will have something to work on if one fails.

    Another interesting proposal was to first send a bunch of micro-rovers, similar in size to Soujerner, to scout a bunch of prospective sites before sending in the expensive ones. This makes sense.

  50. instrumentation by CowbertPrime · · Score: 1
    Team members speculated that Spirit's power boost, like similar ones on Opportunity in October, resulted from wind removing some accumulated dust from solar panels. Spirit captured pictures of dust-lofting whirlwinds on March 10, adding evidence for windy local conditions. Images the next day showed solar panels cleaned of most of their dust buildup.
    No meteorological instruments? Anemometers and barometers are small and require minimal power to collect data continuously...why were these omitted from the primary instrument pallet?

    They've already provided us with one major trajectory mystery, confirmable because there are two of them. They're also supposed to be reaching the heliopause soonish, which should provide even more information that would be slow and very costly to acquire otherwise.

      Actually, I was just musing to myself that it could be a lensing effect caused by the light sources of out own solar system and the entropy involved therein, and not necessarily "painted" on. And there doesn't have to really be a crystal (read: physical) lens, either; it could all be due to some weird gravity envelope of our star or something absurd like that.

      It'd make for good sci-fi tv, no doubt. Especially if the bubble or lens or whatever was shrinking.
