Six years ago today...

I distinctly remember you talking about how successful the mission was nearly 5 years ago when the rover had been on station for over a year.

It is a great success. I'm sure it has been a program management challenge determining how to fund, staff, and operate a program than has gone 'over schedule' for such a successfully long time.

It doesn't seem that long Dave.... I can remember when you brought one of the first photos to Dean's before the Kickoff.... exciting and an incredible adventure.
Congrats! to you and everyone on that team!!

I've always wondered... The mission was always scheduled for 90 sol... but did anyone estimate the "actual" amount of time the rovers would last would be xyz sol? How much longer will they go for?

A few comments that I remembered from Dave's talk back in 2006:

a) a very limited opportunity to do the mission - physics of celestial mechanics imposing some tight deadlines. (sounds like an FRC deadline)

b) very limited weight, and parts list availability due to mission requirements (sounds like the FRC rulebook)

c) a 'challenge too tough', time 'too little' - sounds like some of the GDC requirements

d) software not finished at ship time - anyone in FRC have that problem ? There is a pretty interesting story about how the software was finished enroute, plus the drama of some really bad software problems later on.

e) basic requirement - 90 days. A year later it was all gravy. A few years after that I read somewhere NASA had to chase funding (correct me if wrong) to keep the program going because the rovers kept going and going and going and going......

f) driving the robot involves deciding on a course of action, transmitting or signaling the robot to do the course of action autonomously. Remember 2 years ago Dave talked at kickoff about maybe moving FRC in that direction, signaling the robot to do autonomous or semi-auto things. hmmm.. morse code anyone ?

Happy Birthday Spirit

Should we embark on a manned mission to Mars in the next 100 years, I vote that we bring Sprit back. If that little bot doesn't represent a modern-day epoch in scientific discovery, I don't know what does. The thing just doesn't quit!

Happy Birthday indeed.

Who says we will be finished using it?

Meh, if men are on Mars at that point, Spirit's probably just about done anyway, as the Earth-based labs that will be studying Mars for a while will be too busy with Martian rocks/soil to take in data from either rover. Bring the rover(s) back, give them their x-year maintenance, and send 'em back out to find more cool stuff on Mars, if they're still in shape for that. (If not, Smithsonian or a NASA museum--driving around.)

[JesseK]

I was simply being selfish in wanting the rover in a Smithsonian in DC since I live so close . Hopefully I'll be able to see one of the rovers in person one day ... hopefully.

Six years.

I think what we have here is a case of everyone involved in the design doing their very best under difficult conditions - and, as it turns out, their very best was far more than it needed to be. OK, we'll take it.

It cost a few dollars, but ended up being a huge bargain for us taxpayers. Good thing Dave declined the extended warranty.

Today I sent in a letter of recommendation for a former 1676 student for a NASA internship. I hope she gets it, since she's the type that'll get us to Mars before I leave this life. And I'd like to see that.

Congrats to the team.

Just out of curiosity, what was their Factor of Safety? Was it higher than normal?

I can't find my copy for specifics, but Steve Squyres' Roving Mars discusses it. Essentially, after Lockheed's Mars Polar Lander incident (they didn't read the manual, and their software operated in Metric units when it was supposed to be English units and it burned up in the Martian atmosphere) the emphasis was on a reasonable duration they were SURE they could exceed. They were sure that dust build up on the solar panels would kill them, but luckily the dust build up was slower than they though, and it turned out that every so often the wind would blow some of the build-up off the panels.

Even Randall Munroe had something to say about Dave's other car.

Am I the only one that read this and thought Wall-e?
