Don't know about other missions, I'll try to find out. Sofar found out the ISS is quoted in KM's by ESA, NM's by NASA  |

A historic moment. A bit bittersweet though. On one hand you are celebrating the successful test run of future spaceflight. But then, it feels sort of like you're re-inventing the wheel. Manned space flight technologies should have been further ahead by now.

There's little NASA can do with their limited budgets.

Yeah, that's been the biggest problem. NASA annual budget is $18 billion or a little over half a penny on the dollar of the total federal budget. Defense budget however, is about $600 billion, and accounts for up to half the world's total military budget There's enough room to double the NASA budget at the expense of the defense budget!  |

As said in the article, these are radiation hardened processors that are far more durable than what's in our phones. An iPhone processor will simply fry up in space.  A lot of computer components, including the memory and data storage, on board even today's probes are not built for high performance but rather high durability and to work under limited power requirements. Curiosity rover uses RAD750 computers, which have a clock speed of 110 MHz to 200 MHz, has a DRAM of 256 MB, and a Flash memory of 2 GB. The cost of the processor? ~$200,000.  Edit: Mods, consider revising the thread title. |
