Re: " it is the fastest Man-made thing - and heading to Jupiter at 12,000kph"
According to Space.com, the gravity assist should take it from 126,000km/h to 140,000km/h... El Reg was only off by the merest fraction. [nerdgasm]
NASA's Juno probe is back up and running after unexpectedly putting itself into a hibernating "safe mode" during its last orbit around Earth. juno Juno is back online and ready to rumble "The spacecraft exited safe mode at 4:12 p.m. CDT (5:12 p.m. EDT) earlier today," said the Southwest Research Institute, which instigated …
Too right, some of us could wipe out the entire planet's life if we did that sort of near-light s thpeed thing.
If the RF sent Juno's way was problematic then it's going to fall over when it reaches Jupiter as the fields generating the RF there are quite a lot of dB larger than we can generate from earth.
"'The safe mode did not impact the spacecraft’s trajectory one smidgeon.' With the accuracy that they need for navigation in this type of manoeuvre, I'm surprised that they weren't measuring the trajectory in milli-smidgeons."
What surprised me, was that NASA would even use that kind of arcane scientific terminology in a public pronouncement at all. Because it is, after all, rocket science.
Quite possibly. I imagine that most of the staff at NASA have read the book.
(For those who don't get it, one crew member on a ship comments that all systems are 'normal.' Another then points out that they are hurtling in a one-of-a-kind craft the furthest from earth any human has ever traveled: This is not normal. The first character then rephrases the situation as 'all systems nominal, then.')
Yippie skippy, they went off to some fancy college and got themselves a graduate degree in 'space science'. Fat lot of good it does them if they never bothered to learn even basic science fiction.
Everybody knows when a person or a probe 'disappears' from communication for a while then reappears it is no longer the thing that went missing. It has always been replaced with the consciousness of an alien being or reprogrammed and it is never a positive thing.
I can't believe these assholes haven't hit the self-destruct button yet. This is all going to end in tears. And screaming. Yep, definitely tears and screaming.
Hopefully they mean relative to the Sun. Since most probes are sent out in the plane of the ecliptic, speed relative to the Earth would vary depending on where the Earth is in it's orbit, approaching towards or receding from the current point in space where the probe is.
