16 February 2000: Mars Polar Lander Failure Uncovered? According to someone@jpl.nasa.gov: "A potential problem with the MPL descent sequence may have been located. During footpad deployment for the MPL, tests indicate that the touchdown sensors may have thought that the spacecraft had landed due to the force of landing gear deployment. If this occurred, the spacecraft would have separated from its parachute and descended normally to an altitude of forty meters. When the radar indicated this altitude, the spacecraft was programmed to descend at constant velocity until it touched down. But if the footpad sensors indicated a touchdown, the spacecraft would have shut off its descent engines at 40 meters altitude, dooming the mission."

Not only do I think this was done by Martians at a the probes border routers, but also on all routers within the NASA network. Programs like AED (Alieneldraht) attempt to determine if they can successfully send packets with forged alien addresses, and both it and MFN2K (Martian Flood Net 2000) have code to randomize packets on a per probe basis (not exactly GRITS compatible (Global Redundant Interstellar Troll system) , but still pretty clever and effective.) This means that if you have a /16 probe communications network with several open sourced probe-lets, the alien agents could forge the final two octets, looking like they are coming from probes on Mars. Depending on NASA's probe infrastructure and the Governments political relationship with a particular set of Martians, this can either force the probe to have to sniff on *each* planet, or do its own planet-by-planet debugging of packet flows to locate the actual planet(s) sending the. If no Alien can forge source addresses beyond its own planet, the task is greatly simplified (and you only need to put filterprobes on one planet to stop the flow from one alien agent host.)

(Granted, landing a spacecraft on another planet *is* a tricky thing, but hey, the Viking series seemed to do pretty well..)
In an ideal world yes, but NASA isn't half the agency it used to be. Even apart from the funding issue, it doesn't have the overwhelming public support that it enjoyed in the heyday of the space race, when beating the USSR was a matter of national pride. People (and I mean the average Joe here, not the enlightened /. elite :) ) don't really care any more about what NASA are doing or what's going on - "Oh, it's another Shuttle launch to put a satellite into orbit. *Yawn*."
If NASA don't do at least something then the budget-makers are going to decimate their funding even further, saying "Oh well, they aren't using the money any way." If they were to attempt a large-scale mission such as the ones you mentioned this would take up all of their budget for years and leave them open to criticisms of being wasteful with their money. While the current spate of small, cheap missions isn't doing as well as they might have hoped, they can do enough missions so that they can turn around at any point and say "Look, here's what we've accomplished in the last year. We're still active and worthwhile."
One of the major problems I think is that the technology for acheiving these kind of smaller missions isn't entirely there yet, or at least isn't in line with NASA policy. NASA needs to work on their methodologies - how they launch the missions, how they are managed etc. When they get to the point where almost all missions are successful and cheap then they will be at a point where they can claim they've chosen the correct strategy.
Lets face it, while the Viking series may have done well, the cost of launching them was most likely astronomical compared to the cost of the Mars lander. Those days were a haven of politics as much as science, and it wasn't usually the best solution that was used, it was whichever company were persuasive enough to get the contract.

Another interesting scenario: there was talk of searching for the lander parachute using the Surveyor spacecraft, so NASA asked Lockheed Martin, "Where did you say the parachute would fall again?"

however, most human beings have some sympathy for others, and don't think it's OK to have people starving in the streets. it's like Dennis Miller said: you can't just keep tinting your car windows until the homeless people on the street go away.
now, after saying that you may think I'm one of the "Welfare not space" people. I'm not. In fact I think that our spending on space should go way up.
but the first thing we should do is pay off the debt. If we do that, we'll have $250 billion/year more to spend on whatever, money we now spend on interest payments on the debt.

I think you mean Venus. Mars' atmosphere is mostly Carbon Dioxide, so there's not much Oxygen to actually oxidise anything with. Venus has a very nasty atmosphere (I.E huge clouds of sulphuric acid) that tend to corode things.
No - I did mean the Martian atmosphere. The gases which make up the Martian atmosphere are about 95% CO2, about 3% Nitrogen and 2% Argon. But there is also dust and UV. Because the Martian atmosphere is so thin and the thin ozone layer on Mars, the UV levels on Mars are quite extreme. This UV bombardment of the surface rocks (aka regolith) is thought to result in the formation of strong oxidants on the surface of these rocks. And while the atmosphere is thin, there is enough wind to pick up the surface dust and carry it around, resulting in those pristine circuits and mechanical joints getting gummed up with highly oxidizing muck.
If you are interested in more information, there is an interesting summary of the Martian environment and the possibilities of terraforming Mars here [colorado.edu].

Also, recent successes by NASA, such as the Eros asteroid study and the earth mapping mission (which could have and maybe should have been done unmanned) have attracted a lot of positive press.

(As a side note, the Pioneer spacecraft are still operational, but not being actively tracked because the probes are too far away for us to track the signal!
It's a shame that kind of engineering doesn't happen at NASA anymore. (again, not enough budget to plan and test adequately...)
Why NASA used to work better (Score:3)
Those guys looked good because they launched a lot of birds, and eventually succeeded. If we sent ten probes to Mars over a short period, some would work and some wouldn't, and we'd get data back. Look at Iridium - dozens of launches, a few failures, operational on schedule. (The service isn't selling well, but it works as designed.)

It isn't the most expensive component. Figures are hard to find, but the external tank costs about 50 million dollars. That is about 10% of total costs for a shuttle launch.
We have airplanes that for all intents and purposes can obtain low earth orbit.. add some maneuvering jets and you got a spacecraft - why does it cost a billion dollars to do THAT?!
Please point out the airplane than can get remotely close to low earth orbit, let alone carry a cargo there. Space is hard, drawing pretty pictures of non-existent space planes and bitching about NASA is much easier.

Come one, NASA can get off their butts if we tell them too. The best way to solve this is to cut their budget in half each time they mess up. Yeah. Then they'll have to make missions with less money, less resources, less time, and they will have to succeed. I mean come on, I go to the grocery store every week and it doesn't cost me millions of dollors, nor do I crash each time I go.
Eventually, their budget will be so small, they will only be able to hire one man. That one man will be none only than, Quinn Mallory. I mean, if this college student living with his mom can manage to traverse universes/dimensions on his own, it can't cost that much. There's nothing that he can't do if he sets his mind to it. All we have to do is learn from his diary tapes how to slide, locate and bring him back home before the Kromags run us over, brainwash that goofball that's taken over his body to bring the real Quinn back to the forefront, and then he can start some real work on going to Mars. That's the way to do it...

Looking at the performance of these spacecraft, built with decades-old technology, makes one realize just how much is gained by spending the extra dollars up front and doing the job right the first time. Here's hoping things go half as smoothly with Cassini as they have with the V'gers.

The ages of space explo{r,it}ation:

4. Iridium -- will it make money?
5. Space Station -- why?
Low Earth Orbit is getting easier. This is the result of learning all of the hard lessons the hard way, and not taking the risks for granted.
Mars exploration is still very difficult. Partly this is because Mars is a more difficult environment than LEO. But the constraints of BFC are leading teams to make some of the same mistakes that were made before. The MCO interim failure report [nasa.gov] seems to indicate a certain... well, lack of rigor in the development and operations.
I, too, would like to see a radical change in the NASA Mars Exploration Program / MEP. The current program seems to combine aspects of Iridium technology (commercial practices, comparatively low unit reliability) and NASA program design (one-off design, albeit with component re-use) -- but combines them in a bad way. The addition of political pressure does not help, as opined [space.com] by Donna Shirley, program manager of the successful Mars Pathfinder project.
So, what's wrong with MEP? Simple: There Is Only One MEP. Apollo succeeded because the guys working on it were convinced that the Soviets could get to the Moon. They had real competition. Likewise with Iridium -- until the finances fell apart, everyone thought there would be several competitors snapping at their heels.
The competition for Mars ended when the contract was awarded to Lockheed Martin Astronautics. There was competition at the contract level, but none at the program level.
Look, I don't care if you call it 'Red' and 'Blue' but there have to be at least two competitors. Cycles of competitive innovation, followed by cooperative synthesis, will produce the best results.
OK so JPL has one team already. Hmmm... who else could do this kind of thing? CMU, JHU/APL, MIT, USU, maybe even some Big 10 schools. Start with some GFE hardware -- flight computer, telecom equipment, pyros, motors etc. Hand out $50M to each team and stand back.
Neither team could afford a flagship probe a la Mars Observer ($1B). Perhaps one team would build a single lander with lots of high-tech instruments. The other team might bang out 5 small landers at $10M a pop. In any case there would not be any single team with a 'royal warrant' to probe Mars.
