NASA Making Renewed Efforts To Contact Mars Rover Opportunity (spacenews.com)
NASA is making a new, and perhaps final, attempt to restore contact with the Mars rover Opportunity, which has not communicated with the Earth for more than six months. From a report: The Jet Propulsion Laboratory announced Jan. 25 that it was transmitting a new set of commands to address what it acknowledged are "low-likelihood" events that could have kept the rover from contacting Earth. These new efforts are in addition to the months-long "sweep and beep" campaign of transmitting other commands and listening for a reply from the rover.
The new commands address scenarios where the rover's primary X-band radio has failed or both the primary and backup X-band radios have failed, as well as cases where Opportunity's internal clock has an offset affecting its timing. The commands direct the rover to switch to the backup X-band radio or use its UHF transmitter to contact Earth, as well as resetting its clock. Those scenarios could explain why the rover has failed to contact Earth, but project officials acknowledge that those scenarios are unlikely. "A series of unlikely events would need to have transpired for any one of these faults to occur," JPL noted in the statement about the new campaign.

NASA got to close to something, and the Martians disabled or destroyed the rover.
If rover works it will contact earth eventually. All the whiners and anti-engineering types will always come up with some reason to complain and sell their worthless products to NASA. That has always been true even when the evidence is presented incorrectly by whiners
I misaligned my satellite dish the other night. The first program I saw showed Opportunity and these little green guys were messing with it. At the end of the hour they had put new 22 inch rims with spinners and low profile tires, a crazy new stereo with a coupe big ass subwoofers, neon lights on the undercarriage, lambo doors and shag carpet inside. I think it must have been the martian version of pimp my ride.
Yo dawg, I heard you like played-out memes, so I got you some memes to play with while you play-out your played-out memes.
A series of unlikely events
Sounds like a good title for a TV show
Good grief is that thing ever an obnoxious and intrusive add. It activates when you scroll down a bit, and goes a way when you scroll up a bit, and shifts the view of the page so I can't ever see the first post's summary.
How idiotic.
Silly NASA still messing around with obsolete rovers. Why aren't they building space factories and Mars colonies and mining asteroids? They obviously don't read Slashdot comments. If they did we would be living on Mars by now.
And got eaten by resulting dust storm.
Given how long past it's warranty this little rover lasted, what an achievement for JPL.
I hope they can get things working again, but even if the effort fails, this little rover has gone over and above. It's hard to say good bye and we are sad about it, but we all knew this day was coming. Remember what JPL accomplished with these two rovers and revel in that. This isn't a failure, it's but the end a huge success.
Way to go JPL, you really out did all our expectations and have contributed to a volume of scientific observations that will provide invaluable science and research for decades to come, not to mention some really impressive pictures which are very interesting to just look at. Thank You! Job well done.

Let me see if I understand your nonsensical rant. You want to defund NASA for trying to revive a rover that they have kept working for more than 15 years past the original mission parameters because they are "incompetent". I feel that feat alone destroys your point.
Well, there's spam egg sausage and spam, that's not got much spam in it.
Trust me, NASA, it isn't going to happen!
I've abandoned my search for truth; now I'm just looking for some useful delusions.
Why the hell isn't that fully autonomous? I mean, robot doesn't get any response from home for some time, switch transponder, do a hard reset, whatever. Why would they have to instruct it to do something the robot should be able to figure out by itself?

Normally I would disagree with Gov funded projects. NASA is full of lots of money wasting bloat. But yes, the rover has been an amazing success story. Hopefully when the Chinese or Russians get to Mars they can let us know what happened to it.
They're probably just hesitant to reveal the real story, that Opportunity has simply chosen to stop responding to us. https://xkcd.com/1504/
First, please list all the NASA bloat that you think has occurred. Second, why would you think that NASA doesn't know what happened. The batteries being drained in a dust storm is the exact scenario that NASA predicted more than 16 years ago in their planning. And third, why would the Chinese and Russians getting to Mars help out NASA in this way? Have those countries have designed and built repair bots that can troubleshoot an American rover? I would bet they Chinese and Russian rovers have their own missions and not one thought has been put into fixing another rover.
Well, there's spam egg sausage and spam, that's not got much spam in it.
Yes, do you even understand concept of "good money after bad"? Probably not, go read a economics textbook.
Under the absolute rule of democrat party we let NASA to wasted billions of dollars but that doesnt mean we should continue to do that. Defund NASA and give money back to taxpayers from its was stolen from, or at least put it to securing boarders against rapists murderers and fighting the radical islamic terrorism that has killed so many Americans.
I understand that claiming that NASA is "incompetent" after keeping rover up for 15 years past mission parameters is delusional. Perhaps you need to clarify what incompetent means. Now let's go to your second rant: how much money does NASA get and for what? I'm pretty sure you have very little clue.
Well, there's spam egg sausage and spam, that's not got much spam in it.
Unlike here under democrat party Russians have good goverment that works for its people instead of aganst them. THEY dont suffer wasted taxpayer dollars for useless departments like NASA, plus open boarders and blatant gun grabbing from democrat party extremists.
So yes it is simple logic to state we must DEFUND NASA if we want to put USA first and keep America safe and to compete amazingly in global economy.
I call bullshit. Those craft don't exist, if not a single one has been hacked.

NASA is trying AGAIN and spending many more millions of STOLEN TAXPAYER DOLLARS to "fix" something they could have fixed BEFORE THEY SENT IT OUT, and you are telling me I am the one with very little clue. LOL. You put the tard in libtard.
But obviously it's Aliens.
Jobs in their state is good, jobs for their relatives is better, non profits they can be on the board of and get paid for doing nothing DOUBLE PLUS GOOD
I have a question for anyone who has read more about survivable systems than I have.
Does it make sense to design a remotely operated system to attempt to reestablish communication on its own if its primary communication channel is disrupted? Specifically, to do things like what Opportunity is being commanded to do manually, such as trying to use a backup radio, switching to a different frequency radio, and resetting its clock. These seem like the sorts of things that should be automated. It should be rate limited, and aware of how much on board power it has, so it avoids going into an infinite battery draining loop trying desperately to phone home, but shouldn't it actively try to reestablish communication?

So you admit you don't have any clue to how much NASA spends? That seems like the totality of your argument: you don't know but sure you are right.
Well, there's spam egg sausage and spam, that's not got much spam in it.
You've posted no points with actual facts and keep asserting things without foundation.

I remember reading that there were known spots on the circuit boards such that if that spot cracked due to the cold, the entire rover would fail.
They were known weak-points which lacked redundancy, but the cost of the avoiding them was considered too high. The rovers have roughly 90% redundancy, but approaching 100% apparently has a steep cost curve.
For example, at some point the redundant systems have to coordinate with each other to make sure both are not trying to do something at the same time, which could waste power or put noise into instrument readings. These coordination points are not easy to also make redundant. You need redundancy handlers to manage the redundancy handlers in almost a fractal way, requiring redundant "turtles all the way down", filling the rover with bunches of circuits.

Sorry retarded bitch Alexander Peter Kowalski, you are just a loser who is too dumb to realize you got stomped long ago.
Here is a chronicle of your bitch ass getting beaten on your port filtering statements.
Here is another one where your got beaten hard because you can't back up anything you say. This was about how you claim your shitware can block all hosts in a domain, which it can't.
Then there is your claim that the Chinese copied you but you admit that at best all you have is wild ass speculation and can't offer any real proof or even actual evidence to support yourself.
How about the list of experts you claim support your statements, none of which actually support your work and have been shown to actually be saying things different from what you stated they were.
Maybe instead you can tell us about your "success" where a project rejected your stupid simplistic idea or maybe threaten to sue someone again because you are a insecure little man who is washed up and never amounted to anything.
Better yet you can prove how defective you are by continuing to repeat your debunked BS some more.
Why don't you get your pretend friend to post some fake support and then throw a fit when you get caught.

I see that the retarded bitch Alexander Peter Kowalski chose to show off how defective he is. He has nothing so all he can do is keep repeating his previously disproved statements because he is just too dumb to understand that he lost and is nothing but a failure. Given that he can't follow simple reasoning and logic, his advise on more complex topics like computer security should not be followed. Especially given that he doesn't believe in things that actually provide real provable security.
