Sounds like that person doesn't really understand that NASA is a political entity and the Public Relations of an ongoing successful mission is more valuable long term than more scientifically pragmatic experiments in the immediate.

Sounds like s/he perfectly understood that, but still didn't like it. Often (always?) politics get in the way of actually getting things done in a smart fast efficient manner.

The thing is, you can substitute "politics" for "people" and get the same statement, which is why NASA's political work is at least as important to human space exploration (and, I would argue, long-term species survival) as the raw scientific work.

People have to be continually convinced that exploration of the solar system is a worthwhile expenditure of a lot of money that could be spent on other things. Seems obvious to those who are already thinking in the direction of where humanity is going, but most people do not.

Having worked on mission critical commercial aircraft electronics, I can assure you every part is stress tested before it goes on a plane. Both after its first made and every time its in for service. Supposedly there has been research done showing that stress testing does not adversely affect reliability, at least at this quality level Also, the paper trail is quite literally paper. Its kinda amazing how slow the avi…

It's possible I'm mucking up the jargon, but isn't stress testing electronics what most of us might call "burn-in"? I definitely want the flight control computer burnt in before I sit on the airplane. I was thinking more of physical components, like an aluminum bracket, and you don't want a part with metal fatigue being installed as new.

Correct, thermal testing. Not vibration

I can assure you that the distance took its toll on the rovers, in my understanding. Their wheel surfaces eroded, oil pumps failed, bearings degraded and they ended up dragging dead wheels in the end.

Are you talking about the distance the rovers traveled while on mars? Because that's not what Retric is talking about. Retric is talking about the distance from the earth to mars (hence why they compared it to the moon).

Ah, my mistake; I misunderstood their comment.

I remember talking to a high up on the program at a FIRST robotics event who complained about them running so long. They weren't making any major new discoveries and sucking up resources and mindshare stopping him for kicking off and focusing on new projects. He said nobody would take the PR hit to decide to just end a mission like this so he was stuck.

> I remember talking to a high up on the program at a FIRST robotics event who complained about them running so long. Not surprising at all. Coached a FIRST team for several years. At this point they sell licensed robotics kits with canned instructions for kids to put together and those kids win because of time limitations. The teams that build from scratch and actually contribute discover or learn anything at all ar…

It's well known that the best teams are the ones that eschew using the kit of parts and have their NASA/SpaceX/Autocorp sponsors laser cut their robot chassis for them.

Seems like you might not understand how hard it is to get to Mars, and land safely. (Hint: it's very hard.)

It's still possible to simultaneously acknowledge the fact that we need to repeatedly convince people of space exploration being important while also disliking that this is necessary.

And it was supposed to last 90 days...

It wasn’t supposed to last only 90 days, the initial mission specifications were for a 90 day mission. While it’s an engineering marvel no one thought that it would last only 90 days if it successfully landed and deployed, the 90 days was a minimum figure for the design and also the initial operating budget for the mission.

Semantics. The “supposed to” part means it was designed for 90 days, not that it was expected to fail after 90 days. I was pointing out the marvellous over engineering

Is it possible for someone other than NASA to send a message to the rover? I'd be happy throwing a little money at a project to ping it monthly to see if there is a response.

Mars is half an hour away at lightspeed. It would be too easy to break the rover by conflicting commands.
