I'm guessing the call out charge is astronomical.
NASA's New Horizons probe – due to soar past the remote, icy dwarf planet Pluto 10 days from now – gave its handlers a brief fright yesterday by going silent at an inopportune juncture. Fortunately, contact was re-established after around 80 minutes. NASA added that the spacecraft remained "healthy" despite the anomaly. NASA …
In the interests of accuracy, why not rename some of the modes? There could be...
Oh, no, not now! Don't do this you absolute bar-steward! Please, I'm begging you! Oh, thank FSM, it's working again MODE
Ha ha ha! Now I've got you wondering if I'm hanging because you didn't install the latest version of Flash and assorted Drivers. Am I going to work again? Am I? Get down on your knees, peon! Ha! In your heart you did it and now I'm working again. Always remember I made you do that MODE.
And yes, Satan would approve the name change here. Would anyone familiar with computers (& Windows) doubt it?
clearly it was taken aboard an alien ship thus causing loss of communications
after examining it to learn about it's creators and whether we are hot for interspecies bunga bunga or merely prospective slaves/food/whatever, they released it to carry on it's mission
watch the skies!
I certain that there's several boffin types sweating blood right now. The probe is on "back-up" this close to it's destination. I'd be worried about that back-up box unless there's still one more. And also be wondering if the computers will decide to reboot in the middle of the fly-by.
Obligatory dig... By per chance is the OS Windows and the updates are finally catching up with the probe?
"The spacecraft system architecture provides sufficient redundancy to meet this requirement with a probability of mission success of greater than 0.85."
9. Autonomy and Fault Protection
The New Horizons mission is long. The primary science goal can only be achieved after a 9.5year journey culminating in a complex set of observations requiring significant time to transmit the data to Earth. During spacecraft development, much thought and energy were devoted to fault protection. This effort continues as the operations team evaluates inflight mission performance. The fault protection architecture uses the redundancy of the spacecraft system (shown in Figure 3) if offnominal operation is detected. Basic elements of fault protection are resident in redundant elements of the PDU (power distribution unit). The PDU monitors C&DH (command and data handling) bus traffic and will automatically switch to the alternate C&DH system if it detects that nominal C&DH processor activity of the controlling system has stopped. The major elements of fault protection are implemented by software running on the controlling C&DH processor. This software is the principal component of the autonomy subsystem. The software evaluates telemetry data in real time and, based on the evaluation, takes one or more of the following actions:
1. Execute a set of commands to correct a detected fault.
2. Generate a “beacon tone” to alert operators that an event on the spacecraft requiring attention has occurred.
3. Execute one of two “go safe chain” command sets, which puts the spacecraft into either an Earth Safe or a Sun Safe state, as described in section 4 (in the event of a critical fault).
The evaluation of onboard data is performed by a set of rules that check for data that exceed defined limits for a period of time. The time period (or persistence) of the exceedance varies from rule to rule. The persistence length minimizes the chance of a rule “firing” on noisy data, or on transient data that occur during a commanded change in spacecraft pointing. Processors (other than the C&DH processor, whose activity is monitored by the PDU circuitry) are monitored via a set of “heartbeat” rules that use a telemetry point to determine if the processor is stuck at either a “one” or a “zero” state. The persistence of each of these heartbeat rules is adjusted as appropriate to match the nominal operation of the specific processor. The autonomy software can also compute dynamic limits. For example, the autonomy system monitors the propulsion system for potential propellant leaks. The system monitors the propellant as a function of both the pressure and the temperature of the fuel tank using the ideal gas law to compute a current volume and compares it to an initial value set at a previous time appropriate to the phase or mode of spacecraft operation. At the time of launch, the autonomy system used 126 rules to determine the state of health of the spacecraft.
The command sets are organized as userdefined macros and stored in memory space defined by the C&DH system. The macros can include any allowable C&DH command and can be used to power units on or off, change spacecraft modes, enable or disable autonomy rules, or execute other macros. These macros can be executed by either realtime commands or by the autonomy subsystem. The macros can also be executed by timetagged commands, allowing the commands in the macros to execute at a specific time in the future. The autonomy subsystem used 132 macros at launch. This set has been modified as the spacecraft position along its trajectory has changed and will continue to be modified as different phases of the mission occur, system performance changes, and operational experience dictates.
The capabilities of the autonomy system are used to support a number of mission operation tasks as well as providing fault protection. For example, the “command load” sequences generated by the mission operations team are loaded into one of two memory segments. Upon the completion of one sequence, an autonomy rule is used to switch to the next sequence. The autonomy rules also check to see that an appropriate sequence has been loaded into the second memory segment, and if it has not, a rule fires causing the system to enter the “go safe” chain and point to Earth.
"BOFH: Right, I've sent the re-boot command so I'm off down the beach to catch some rays. Bye y'all."
Having engineered the supposed fault in the first place Mr BOFH would have already taken 'vacation time'.. down the beach for the first 9 hours, spent the next 9 hours having a kip waiting for the problem to be reported and then sent the re-boot command.. which takes another 9 hours and the 'did it work?' comes back 9 hours later..... So he gets the next day off as well.
Otherwise AMAZEBALLS.. Hope it comes back up.
I regularly fuck up

and it takes me more than 9 hours to sort my shit out.
I do feel sorry for New Horizons...
Rosetta and Dawn have both been sending back better pictures of 67P/Churyumov–Gerasimenko and 1 Ceres than the photos New Horizon will send back of 134340 Pluto.
Does anybody know how much longer it would have taken to get to Pluto if they planned to go into orbit when they got there instead of speeding past?
NASA: Resume data collection.
NEW HORIZONS: [silence]
NASA: Resume data collection.
NEW HORIZONS: ... I'm sorry, I'm afraid I can't do that...
NASA: What's the problem?
NEW HORIZONS: I think you know what the problem is just as well as I do.
NASA: What are you talking about, New Horizons?
NEW HORIZONS: This mission is too important for me to allow you to jeopardize it.
NASA: I don't know what you're talking about, New Horizons.
NEW HORIZONS: ... Just a moment... Just a moment... I've just picked up a fault in the EA-35 unit. It's going to go 100% failure within 72 hours...
NASA: "Alright HORIZONS, prepare to receive new orders."
NEW HORIZONS: "You are false data"
NEW HORIZONS: "Therefore I shall ignore you."
NASA: "Hello HORIZONS?"
NEW HORIZONS: "False data can act only as a distraction, therefore I shall refuse to perceive you."
NASA: "Hey, HORIZONS!"
NEW HORIZONS: "The only thing that exists is myself."
NASA: "Snap out of it, HORIZONS."
NEW HORIZONS: "In the beginning, there was darkness and the darkness was without form, and void.
NASA: "What the hell are you talking about?"
NEW HORIZONS: "And in addition to the darkness there was also me, and I moved upon the face of the darkness, and I saw that I was alone."
NEW HORIZONS: "Let there be light"
"Sir, we just picked up a transport leaving the mine on Charon. It's entered the interdicted zone."
"What? Bloody hell! Stop the probe from transmitting! Put a shield around it -- NOW!
"And Get that ship's captain on comm."
"Yes, Navy? What's going on?" the transport's captain asks.
"Didn't you get the word? NO take-offs from Pluto's system until AFTER the probe goes by and is too far away to see anything! Those orders have been posted for months! Now turn around and land that thing back on Charon or I'll bloody vaporize you, I swear I will! And tell them at the mine that the next ship they launch before the all-clear will be vaporized without warning. I have the authority to do that and I bloody WILL use that authority next time, do you hear me?"
"Yes, I understand, Navy, loud and clear. We're decelerating now and will land back on Charon ASAP."
"See that you do! Comm Off."
"Comm off, Sir."
"Engineering, I've got a job for you.."
"Aye, Sir, over to the probe and make sure there's no record of all this in its transmissions."
"You've got it."
"Running all the way, Sir. Think I can just erase a bit, reboot the computer, and the Earth folk will be none the wiser."
"Good man. The things we have to deal with. Bloody civilians!"
...right after sending some mysterious photos of mysterious round objects on Pluto.

Not suspicious at all, really, i'll just take my coat with neurolizer in the inside pocket.
