Couldn't they just give the thing more memory? That last 32 GB of data was just too much for the budget?

"Nah, we'll just uninstall and reinstall software. We need that $8 for rocket fuel."

As I understand it, more powerful computers are significantly more sensitive to the things that endanger them on these sorts of missions. No idea if that's the reasoning here, or if they even don't HAVE computers that could store both on board, and aren't for another reason.

Computer memory is very susceptible to damage from cosmic rays. (That is what determines the lifetime of satellites.) By installing the software now, they can simply not use any memory locations that were damaged during shipping. If they had installed on Earth before shipping, random pieces of various software would have been lost because they were on sectors damaged in transit. Taking the time to install now means that the rover's lifetime is much longer and performance much more reliable.

Battery counts for everything, and you need more power for more memory. Not to mention more space, because you can't just leave the chip exposed like it is in your laptop/desktop.

It's an elegant solution - send it up with landing code and then switch out to more specialized code if it lands successfully. There were probably routines in place in case something went wrong with the landing that they don't need anymore. No reason to build a system that can hold more than you need at any given time if you don't have to.

I met a 23 years old blonde hottie last week. I bedded her yesterday. Great tits, very fun personality. Terrific in the sack.

But I'm worried because during a conversation we had on her rooftop about space stuff (basically me explaining why the Moon apparent rotation changes everyday, point to her where Jupiter and Venus come up on the sky and telling her about the Perseids this weekend.) At some point, the Curiosity came up and then she told me we'd never been to the Moon. Told her it's impossible because the Soviets would have exposed USA silly, but then she insisted and told me some stuff about how camera film doesn't work on the Moon due to the conditions there, so how did they take pics? I just pokerfaced because I want to keep bedding her but inside I was all like this:

Radiation-hardened computers/components are bloody expensive.

According to the NASA site, the rover has 256kB of EEPROM, 256MB of DRAM, and 2GB of flash memory. Fitting everything into 256KB of EEPROM doesn't sound like fun at all, nor would it leave a lot of spare space. I imagine the flash memory is used for stuff like photos and data, while the EEPROM is used for the rover OS and other computer functions. It probably makes more sense to have a "cruise & landing" OS installed and then install a "explore and DO SCIENCE" OS once the rover actually lands and passes all the self-checks.

The computers aren't really beefy either: 200MHz RAD750 CPU which costs around $200,000 and is capable of 400 MIPS (somewhat less than a Pentium Pro from 1995 -- an Intel Core i7 2600K is capable of 128,300 MIPS).

One of the issues with the technology used on missions such as this is that by the time every component has gone through design, testing and finally built into the rover/satellite/whatever by the time it launches it is already well out of date. According to wiki design began in 2004 and all equipment was settled upon by 2008. Just to put this in perspective, the first iPhone wasn't released until the middle of 2007.

Oh, when I told her the Soviets would have exposed NASA very easily just sending a signal to the beacon or some other methods, she said it wasn't gonna happen because even though we were in the "Cold War", USA and USSR were actually friends and wouldn't expose one another.

She's so lucky to be good looking because, jeez...

Dude, seriously, dump her before she makes you retarded. It really isn't worth it.

I dated a hot blonde English teacher. We watched Alien (she had never seen it) and right off the bat she started laughing about how silly it was, after all, they're in a space ship but they're not wearing space suits!

She was shocked - SHOCKED - to be told that you didn't have to wear a space suit the whole time you were in a space ship, because of the whole pressurised cabin thing. She thought that they had to be worn constantly...otherwise your gravity would fall out.

Higher capacity chips use smaller and smaller circuits which are more and more susceptible to damage from radiation.

Remember that the Earth has a great big honking magnetic field from our spinning iron core that helps shield us from quite a lot. Mars does not.

Curiosity also uses a radiation hardened version of the PowerPC G3 era CPU.

RAD750 is a radiation-hardened processor, based on the PowerPC 750. It is intended for use in high radiation environments such as experienced on board satellites and other spacecraft. The RAD750 was released for purchase in 2001. The Mars Science Laboratory and Mars Reconnaissance Orbiter spacecraft has a RAD750 on board.

The processor has 10.4 million transistors, is manufactured by BAE Systems using either 250 or 150 nm process and has a die area of 130 mm². It operates at 110 to 200 MHz. The CPU itself can withstand 200,000 to 1,000,000 Rads and temperature ranges between −55 and 125 °C. The RAD750 packaging and logic functions has a price tag in excess of US$200,000: the high price is mainly due to radiation hardening revisions to the PowerPC 750 architecture and manufacturing, stringent quality control requirements, and extended testing of each processor chip manufactured

This is in fact exactly what they do. Watch the NASA JPL Curiosity press conferences for more (link, I believe it was yesterday's that covered this), but there are actually four different software packages that they've prepared for different stages of the rover's lifetime. They've also got redundant computers onboard, so they can load new software in one and test it before fully committing to using the new software.

Here's a freebie for ya NASA/JPL: Make a rover that goes over 3mph. Think how much faster this could go if the rover took off at 50 mph. Obstacles Schmobstacles. It would just go flying over like a railroad crossing lol. All you need is a self-righting arm. Also I have your power supply figured out. Just go look up germanium diode radio (multiply it) and attach it to a slow drain cap bank as a battery. There are tons of radio waves bouncing around up there. Heck you could even build a static charger from a tube on the front that the dust blows past and creates the charge similar to the old sandblasting pvc trick. Neither rely on the dusty dusty Martian view of the Sun.

/at least it didn't crash trying to play "Song 2" like Beagle lmao.

Well out of date relative to the consumer market, certainly, but it's also built to completely different constraints. The most important factor on a space probe is MTBF while operating in an environment hostile to the equipment. Redundant systems are an exorbitant expense- each ounce you lift increases the fuel costs significantly- so you need to make sure each component is as failure proof as possible.

Nobody really cares what the clock speed on the probe's CPU is so long as it's fast enough, and the chip doesn't crap out when slammed with gamma rays.

Your choice: a modern chip with loads more memory that will probably get fried in space or a chip that is radiation-hardened for space flight that has proven record of actually working long term in spaceflight.

NASA's team choose chips that they know will work. If your computer stops working, you probably pay a thousand bucks at most, though probably a few hundred for most people, and replace it. If Curiosity's computers stop working, then you lost a couple billion dollar's worth of equipment. (Actually NASA sent redundant computers just in case, but that is besides the point.)

In any event, the chips/computers sent on space missions are always seem under-powered compared to a top-of-the line PC here on Earth because of the requirement of surviving the radiation, the heat, the cold, etc. found in space and because the chips must be far more reliable than what ordinary systems are. And while NASA officially is planning on a 2-year mission, they are hoping for a whole lot longer. Opportunity has been operating on Mars for over eight years. Its computer system has been operating for over nine years if you include the flight to Mars. Has any computer you have lasted that long under continuous use without as much as replace a single part? At Mars, no one can change out a motherboard, fix a broken temperature-control mechanism, etc.

Probably extra memory cost UPTHEA$$ in 1999 when the system was designed.
