Thanks, but I haven't done anything, but I can take the "thanks" of the people and pass it over to THEM, on your behalf !

If USA stands for Unconditional Support of all Astronomers then a big yes, thanks to USA / NASA, thanks to humanity !

Sorry...no lobby here for antiterrorism.

The glitches in space continue, now it's New Horizons turn, unfortunately.

Good news, snafu resolved! Some timing issue for something, sort of, I think. Here's the article:

Hopefully on Wednesday we'll all be looking at the next set of LORRI images.

It sounds a bit like the glitch that sent Hal on the rampage in2001: A Space Odyssey?

Haha!
I read a bit about it on the planetary society website. They said the main computer overloaded from doing too much at once and switched to another computer. I immediately thought of the famous 1201 alarm when Eagle was near landing on the moon.
They say this glitch could not happen when New Horizons is in (feck i cant remember the name now!) the main mission mode. At the moment it is in some other less critical mode.
They still lost a fair bit of data though but are not too concerned by the sounds of things.

1% or so

http://www.theregister.co.uk/2015/07/06/nasa_new_horizons_cockup/

Stern estimates that less than 1 per cent of the science returns from the probe were lost, and none of it was critical data compared to what will be collected as the probe gets closer to Pluto.

Wow thats a much better figure than i heard! Yer wan Emily Lakdawalla at the planetary society was talking to someone and they mentioned 6% but it might be of what they hoped to get that day.

And the first images from yesterday are up now. It's becoming more and more detailed and more and more puzzling. There don't appear to be any huge or big craters, it's strangely reflective (sort of like clouds or mist or frost maybe, haven't got a clue to be honest).

SarahBM · 08-07-2015 10:03pm

It's gonna take 16 months apparently to send back all the data they'll collect over the next week.

Their's a sky at night special called Pluto Revealed on Monday 20th at 10 on BBC4.

Pluto's heart is now showing:

Looks more like an X to me than a heart assuming what the bottom right side turns out like.

irishgeo · 09-07-2015 9:39pm

in reality how far away from pluto when it passes by and how fast will it going?

13,000Km away, whizzing past at 14Km/s.

In 4 days, 14 hours and 57 minutes.

Isn't it just a big lump of ice and rock?

Id be far more interested in sending probes like this to examine the moons around Jupiter.

Its going to happen alright. I think there's landers planned as well, although not Europa.
We must attempt no landing there.

Some good little vids here "Pluto in a minute" if you've 10mins to spare.

Talks about speeds, not knowing when to start taking pics cuz they don't actually know "exactly" where pluto is, why Horizon can't stop. Good stuff.

Will Pluto be reclassified as a Planet? Maybe.

Q&A with some of the main people.

greedygoblin · 11-07-2015 11:59am

That 3rd criterion in the official definition always seemed a bit wishy washy to me. He made a good point that if Pluto fails the test then Neptune must, by extension, also fail.

Even if the dwarf planet category remains in place, at the very least I hope this mission will lead to a more robust definition.

I have nasa's "eyes on the solar system" up on my pc. One thing i would like to know is: is what i see on screen "live" or based on the received signal, in this case 4.5hrs delayed? So if nasa sends a signal to new horizons to point LORRI at pluto, does the "live" image i see on my pc move at the same time as the real thing. This is important stuff!!

NASA aren't sending instructions to the probe anymore, it's all automated.

With respect to the photos updating, they wouldn't be in any way 'live' (even accounting for the 4.5 hour lag). The probe will be collecting a lot of data, not just photographs, and its connection to Earth is somewhere in the region of 1 kilobit per second, it also can't send data to Earth all the time, it needs to rotate and point its antenna in our direction to do so.

During the encounter it will go quiet, do its work, and only begin transmitting to Earth again once it has left the Pluto system. It will start back up with a status report which will let NASA know whether it completed its mission before it starts beaming back the goods.

Cheers for that. Yeah i was reading a bit on the planetary societies website and it said as much. On the "eyes on the solar system" it is a computer rendering of the probe but it is rotating slowly at the moment with all its sensors lighting up various areas of pluto, charon etc. I was wondering if this was "real time" or not. I suppose it is??
Anyway, 18h45m left to go! Popcorn is ready!:)

Ah I guess I misunderstood you.

I haven't looked at Eyes on the Solar System myself, but I'd bet it would be 'live', since they know exactly what the probe should be doing right now.
