Phoenix Headed for Martian North Pole in 2007
jschuur writes "After narrowing down the selections to 4 finalists, NASA has chosen the Phoenix Mars lander design for its 2007 Scout Mission to the planet Mars. Phoenix, a joint project between the University of Arizona and Planetary Laboratory was designed after the doomed 1999 Mars Polar Lander and recycles much of its design and instrument ideas. A staggering $325 million grant was awarded to the University of Arizona for the project, which will also include Canadian participation. Phoenix is scheduled to land on Mars in May of 2008."
When are we going to see a sample return mission?
That will be a big advance...
A staggering $325 million grant was awarded to the University of Arizona
I don't see what is so staggering about this amount. For example, I'm guessing hundreds of millions of $ are spent every year designing cars. Cars that are never more than a few miles away from a local garage. If your sending a device a few million miles away you'd want to be pretty sure it's going to work. Not a inexpensive proposition. There are no Pep Boys on Mars
In "The Case for Mars," Zubrin talks about the court bureaucrats in China. The emporer had opened up china in the late 1300s and sent treasure fleets to Indonesia, India, Arabia, and even the west coast of Africa. They had seven masts when European ships had at most two.
Then the emporer died. The bureaucrats though he had wasted funds on a folly of an idea (exploration) when more important things needed to be done at home, like irrigation projects. They ordered the fleets destroyed just as they were about to enter the Mediterranean, and China was subjugated by Europeans who had the will to explore and the courage to accept the risks.
Why do I bring this up? Because it's ideas like yours that poison exploratory programs. Instead of grand gestures, you want small cheap steps. You speak of needs at home when they can be solved by innovating for the world. Material hyper efficient fuel cells and computers, inexpensive access to fusionable materials, and cheap metals and chemicals are all available in space. We must have the courage and conviction to simply reach out and grab them, and this can be done for a small percentage of the GNP. Merely increasing NASA's budget to the same percentage of the federal budget as it was during the Apollo era and providing a lofty goal will be enough for NASA to land several humans on Mars and more (like develop an economical heavy-lift launch vehicle). We simply have to want it enough.
I'm in the hole of the broadband donut.
Dislaimer: I write software for Mars missions, including the 2007 Pheonix mission.
I hope they haven't recycled the imperial to numeric conversion code.
I must say I'm really tired of hearing about this every time there's an article about a mars misson. I mean, no one says "I hope they haven't recycled those overflow errors" every time an Ariane 5 rocket is lauched! Was it a stupid problem? Yes, however people seem to forget how rediculously hard it is to successfully launch a mission like this. Yes it's very easy to prevent a single mistake, but thousands of potential mistakes? Our track record with Mars probes is twice as good as the nearest competitor (Russia) and it's looking to continue that way.
Somebody want to contribute an open source alternative to them?
Look. The people working at NASA know how to write this stuff. That's not the problem. The problem is that on large scale projects like this, it's entirely possible for things like this to be overlooked... People tend to worry about the "hard" stuff rather than the easy stuff. And as for why they even have to convert units, as far as I understand NASA generally uses metric, it is the american aerospace companies that generally insist on using imperial units.
Also, Open Source is *NOT* the catch-all answer for everything! The development team I'm on uses linux for our development, and our software will be running on a lot of linux (and windows) boxes during the mission. We love open source, and even use some open libraries (such as castor) in our code as allowed (we are not allowed to link to GPL code of course).
However, I would cringe if the flight software was some open source deal... I mean, looking at the linux kernel sources, (some say it is the gem of open source) I wouldn't want to have to depend on anything written like *THAT* to handle flying in space. Great for on the ground where we can fix/replace/patch if there's a problem but... It's not cleanly designed and implemented like, say, QNX, etc. Few people alive have experience writing software for spaceflight systems, and I expect they they know just a little bit more about it than even the best of linux hackers do.
I guess I just don't understand why the parent post was modded insightful. Nothing personal, in7ane, but really!
