I thought it was supposed to be some weeks before we see the real hi-rez pictures. That image is already pretty awesome.

It is - that was taken from 476k miles. The closest approach was under 8k miles. It should phone home around 9pm tonight to start the data download...that will last 16 months.

NASA
New Horizons' almost 10-year, three-billion-mile journey to closest approach at Pluto took about one minute less than predicted when the craft was launched in January 2006. The spacecraft threaded the needle through a 36-by-57 mile (60 by 90 kilometers) window in space -- the equivalent of a commercial airliner arriving no more off target than the width of a tennis ball.
Because New Horizons is the fastest spacecraft ever launched - hurtling through the Pluto system at more than 30,000 mph, a collision with a particle as small as a grain of rice could incapacitate the spacecraft. Once it reestablishes contact Tuesday night, it will take 16 months for New Horizons to send its cache of data - 10 years' worth -- back to Earth.

Thankfully, New Horizons is not coming back. And good luck following the path back past Jupiter.

Re: SPACE - random thread about space stuff
I totally understand why we couldn't have realtime coverage of the Pluto flyby -- time delay, low bandwidth, limited power. But as someone who sat up watching all of Voyager's flybys -- including the "Neptune All Night" coverage -- I'm a little disappointed. And the most exciting feature of Neptune's flyby was a cloud named Scooter.

Heard a rumor Pluto is larger than they thought.

Re: SPACE - random thread about space stuff
In addition to the things you mentioned: low signal means only the 70-meter dishes of the Deep Space Network can pick up New Horizons' signal. And there are only 3 of them. And the Earth rotates, so they're not all pointing at NH at the same time, and NH has to wait in the queue for dish time just like any other spacecraft. Talking to Pluto is hard.Kraken wrote:I totally understand why we couldn't have realtime coverage of the Pluto flyby -- time delay, low bandwidth, limited power.

Watching NASA TV showing one of the hi-res images of Pluto. I have to say, I'm impressed. And amazed. No impact craters on the image they showed, suggesting that it could be geologically active. And that the mountains could very well be made of water ice.

I caught just a glimpse of that image on a bar TV tonight. Was hoping the newscast would come back to the story but I missed it if they did. When you vacation in the mountains you're nearly off the grid. Or rather, you're on the emergency backup grid.

WOW! Wonder what would be different if they made that camera today.Enough wrote:Cool article about the camera on board New Horizons.
Also, I would have thought the Hubble Telescope could take better and sharper images of Pluto than that! I mean it can take amazing photos of galaxies light years away! Why can't it take really sharp photos of something relativity really close?

Math at the link.Galaxies are far away, it's true, but many of them are bigger than they are far, at least by comparison to the worlds within our solar system! Think about that for a moment -- how something that is millions of light-years away can still appear a thousand times bigger than something that's inside our own solar system.

Pluto is super crazy tiny:Binktopia wrote:Also, I would have thought the Hubble Telescope could take better and sharper images of Pluto than that! I mean it can take amazing photos of galaxies light years away! Why can't it take really sharp photos of something relativity really close?
so while it's relatively close on an interstellar scale, it's still pretty darn far for something so tiny. Meanwhile, the other things Hubble took pictures of were very far away but also HUGE.
You see something like the Pillars of Creation:
and you think "ok, that's probably pretty big." But you may not realize that each pillar is 4 light years tall.

FWIW, that's 3,330 times bigger. Pluto's .06 arcseconds = 0.00001666666 of a degree.
