Umm, isn't this the first step towards the Doom 3 premise? I mean do we really want to start exploring Mars? It'll just eventually lead up to colonization via the Union Aerospace Corporation. Please somebody think of the poor Doom space marine that will have to go through this.

intermediaries for human travel. by bagel2ooo · 2004-08-25 21:27 · Score: 3, Interesting

While I think a manned mission to Mars would be a wonderful idea. I ponder if we would be able to collect enough data to see if using "greenhouse" gases to supply Mars with a more human-suitable atmosphere would also be a good long-term goal. I know that would probably negatively impact our manned missions there for quite some time until the "incubation" is well underway or finished, but I think that with what resources we've been able to find Mars may be more viable for a station or colony than mars.

  According to Chris McKay from NASA they will be. He's a big terraforming proponent and he outlined a near future mission in which a rover will scoop up some dirt into a bell jar, and they will attempt to grow a mustard plant. He said they'll probably have to do it on the moon first for political reasons but it's on the works.

  Landing on an earthlike Mars would be nice but not totally necessary for early astronauts. I'm about at pro-terraforming as it gets but even I think that landing humans on an un-terraformed Mars is best for science.
  
  At a talk given by Chris McKay this weekend, he was asked something like "when do we give up the search for life and start terraforming?" That's kind of a sticky question because it's kind of like proving a negative. However he pointed out a region in the southern hemisphere which is older than the north, still has an earth-strength magnetosphere and is Siberian in nature. He said that once a kilometer deep core is drilled, checked for life and nothing is found that there is almost certainly no life on Mars nor was there ever.
  
  It will take people to do that investigation. My personal hope is that nothing is found and terraforming can begin.
  
  For a good treatment of terraforming, read Robert Zubrin's "The Case For Mars".

Since they found indications of lots of frozen water near the surface in the south polar region, I wonder if there are any plans to send a probe/rover there?

They found "copius hydrogen" in the area, and "Researchers interpret the hydrogen as frozen water", but can we be sure without taking a look on the ground?

  No, this is the lander where the cause of the crash was thought to be "spurious interrrupts" from the sensors in the landing legs, during landing. Apparently that made MPL conclude that it was already on the ground, and it cut off its engine. Boom. Also adding to the accident was bad management in the project, and too many inexperienced people on the team.

Working Overtime? by strook · 2004-08-25 21:49 · Score: 4, Insightful

Wow, the orbiter lasted even longer than the estimated lifetime. Is anyone else noticing the inevitable pattern? NASA launches some sort of mission, gets some positive press, then a few months later more great news! Turns out the mission is lasting even longer than the estimates!
Like the Mars rovers for example:
Mission engineers have analysed power data for both Spirit and Opportunity which shows the vehicles are performing much better than they had expected....
But the mission team adds that its original estimates of Mars' environment and the rovers' performance were very conservative.

If I was smart enough to be a NASA engineer I think I'd figure out that people are much happier with your performance when you exceed expectations. It's not like anyone knows what to expect from a Mars orbiter anyways. Nobody looks at the mission statement before launch and says "400 days? Gee, for 3.3 billion I expected more in the range of 550-580 days."
Not anyone I know anyways. Maybe other people have more astrophysicist friends.

  With things like satellites and rovers, whoever is paying for it says, "We want it to last 90 days / 2 years / 10 years." Then the company actually building the device charges them for it. If it's going to last 10 years, you'd better have a lot of backup in case of failure, which adds complexity to the software controlling the device... all of which rapidly escalate the price. So, when NASA says they want the rovers to last 90 days, they're built to last 90 days. Not less than 90 days, because then NASA will be mad. So inevitably, if you've done your job right, it's going to last a little bit longer. You don't just use the Mean Time to Failure, because that means that 50% of the time, you're going to fail before the mission end. So, things last longer than "expected." Then eventually things break, and because the device is so expensive, they pay people a bunch of money to sit around a table and try to figure out how to work around the thing that broke. You can't do this ahead of time because then you'd be spending a LOT of time trying to figure out how to work around EVERY possible failure, and you can't always do that. I wouldn't be surprised if the company that built the rover lost some sort of bonus because of the failure before mission end, but probably not the complete bonus because they were able to work around the problem.

The fact that Mars has frozen water is one of the biggest discoveries of Odyssey. That is great to know, but it doesn't tell you much, only that a lot of water is currently on Mars in a frozen state.
The rovers' task is to find out how exactly that water influenced Mars in the past (and maybe even present). Long lasting huge oceans? Short wet periods? Or maybe only moist periods, not really wet at all? These science results will then be used to give a future mission a better chance of finding life, or proof of past life. If there ever was life on Mars, of course.

  The radiation on mars will not be nearly as big a deal as the trip to mars will be. It is almost certain that initially, we will have to live underground rather than on top. If we do so, it protects us from Radiation, 300 MPH winds, Easier to insulate, etc.etc.
  
  I am in hopes that we will send a private mission to mars and not have them return. It would be far more useful to send a small mission on a one way trip, with a supply ship once a year. They could build a small base, expand our knowledge of Mars a million fold over what simple remote vehicles do today, just due to the fact that they would need all sorts of cpu power there. In addition, they would be able to control system there quickly.

Both the Jupiter Gallileo and Venus Magellan projects went triple their design lifespans. However, they could have gone even longer, had NASA not canned them. Both were getting "creaky": insufficient propellant to do much, and instruments breaking down. Plus it costs a fair amount of money- up to 30% of the original mission cost per year- for a slice of the Deep Space Network and scientist to run and analyze the data.
We'll probably see this debate about the Mars Rovers if they survive into 2005. Both are already 2.5x their design lifetimes, have some instrument failures (a sick wheel motor, a dead spectrograph), and are tying up a couple hundred engineer and scientists full time.
