LOS ANGELES — A spacecraft that gave scientists their first peek into a comet's icy interior will explore no more, NASA said Friday.
The space agency declared an end to the Deep Impact spacecraft after it unexpectedly fell silent. Engineers tried for a month to regain contact, but lost hope.
Mission scientist Jessica Sunshine of the University of Maryland said she was "saddened at the loss of an old friend."
Deep Impact put on a celestial fireworks display July 4, 2005, when it fired a projectile into comet Tempel 1. The high-speed impact carved a crater and hurled a plume of debris into space, giving scientists their first glimpse of the comet's frozen primordial ingredients.
Afterward, Deep Impact journeyed toward comet Hartley 2, flying through a blizzard of ice particles and escaping unharmed. It later flew by the distant comet Garradd and also observed stars in search of Earth-sized planets outside the solar system.
Before Deep Impact lost contact last month, it was studying another comet named Ison that could shine as bright as the moon when it makes a close swing by Earth in November.
The cause of the failure was unknown, but engineers suspect the spacecraft lost control, causing its antenna and solar panels to point in the wrong direction. Without power flowing to its onboard computer, Deep Impact likely froze to death.
Scientists were disappointed at the timing of the silence that cut short their observations of comet Ison and future plans.
"It is hard to say goodbye," said mission scientist Lori Feaga of the University of Maryland.

NASA | Chasing Comet ISON

Comet ISON (C/2012 S1) may become a dazzling sight as it traverses the inner solar system in late 2013. During the weeks before its Nov. 28 close approach to the sun, the comet will be observable with small telescopes, and binoculars. Observatories around the world and in space will track the comet during its scorching trek around the sun. If ISON survives its searing solar passage, which seems likely but is not certain, the comet may be visible to the unaided eye in the pre-dawn sky during December.
This animation shows two views of comet ISON's path through the inner solar system. The first is a view following the comet along its orbit. The second is a view perpendicular to ISON's orbit.
Like all comets, ISON is a clump of frozen gases mixed with dust. Often described as "dirty snowballs," comets emit gas and dust whenever they venture near enough to the sun that the icy material transforms from a solid to gas, a process called sublimation. Jets powered by sublimating ice also release dust, which reflects sunlight and brightens the comet.
On Oct. 1, ISON passes within about 6.5 million miles (10.5 million km) of Mars. As it goes by, it may be visible to some of NASA's Mars rovers and satellites, including the Mars Reconnaissance Orbiter and Curiosity.
Then, on Nov. 28, ISON will make a sweltering passage around the sun. The comet will approach within about 730,000 miles (1.2 million km) of its visible surface, which classifies ISON as a sungrazing comet. In late November, its icy material will furiously sublimate and release torrents of dust as the surface erodes under the sun's fierce heat, all as sun-monitoring satellites look on. Around this time, the comet may become bright enough to glimpse just by holding up a hand to block the sun's glare.
Sungrazing comets often shed large fragments or even completely disrupt following close encounters with the sun, but for ISON neither fate is a forgone conclusion. Whatever happens, scientists will be able to learn more about comets by how it interacts with the sun's tenuous atmosphere, the corona.
Following ISON's solar swingby, the comet will depart the sun and move toward Earth, appearing in morning twilight through December. The comet will swing past Earth on Dec. 26, approaching within 39.9 million miles (64.2 million km) or about 167 times farther than the moon.
No the "new object" its not a spacecraft as some are reporting....

Slooh.com's Canary Islands Observatory captured asteroid 433 Eros seeming to fly with Comet ISON on September 24th, 2013. This 2nd largest near-Earth asteroid -- which has been visited by the NEAR probe -- is traveling faster, along a different orb
Aprox 1997 Hale Bopp came around and I watched it through binoculars from my front porch. It was a beautiful spectacle. Nothing changed, I brought my family up and worked at the same time, as did my husband.
I still remember the magic of the universe, but nothing changed.
Things have changed now but I believe it's not the comets.
I believe it's knowledge through the Internet.
My thoughts only.

Some fantastic images here; http://brucegary.net/ISON/
Well if Elenin accomplished anything it was to make people too scared to talk about catastrophic possibilities or else they would be labelled fear mongers. Maybe the whole thing was created to discredit those "Chicken Littles" who feel it in their gut that one day the sky really will fall. I don't know how or when but the universe is cyclical so it will definitely happen again. What I do know for sure is that our governments are shady as you know what and they are up to something.
This video is very well done. Is it true?? Who knows, but it's something to think about. If it scares you into buying some food and water...even better.
Much love

Thanks Carolin ... very good one.
Very compelling (short) interview regarding ISON as it passes Mars.
(distributed by James Gilliland in his newsletter).
Wow.
http://thelightofdayradioshow.com/ar...goes-Comet.mp3
New interview confirming some things as well as raising an interesting question about why have we not heard from the European equivalent of NASA with images of ISON from their equipment around Mars???
Hmmmm ... no government shutdown there ...

Hmm, from this website: http://www.rememberthe13th.com/
NASA has made a historic discovery that will shake the entire planet. This announcement will be released to the media on November 13th, 2013. It will be a day to remember and One for the history books. Spread the word to your family & friends and sign up to stay updated!
Note: Originally posted to be exposed on 11/13.. now to be released on 10/6
Probably hype, I'm guessing, due to pretty strong language: "A historic discovery that will shake the planet"!!!!!!!!!!!!!!!
Below is what is posted on the NASA website (http://notice.usa.gov/):
Due to the lapse in federal government funding, this website is not available.
We sincerely regret this inconvenience.
For information about available government services, visit USA.gov.
So NASA is considered a non-essential agency! Quite an interesting time for them to be shut down.

UFO Caught Behind Comet Oct 4th ISON 2013?

What ever this is it is huge. Is it hiding behind Ison or possibly steering it?
Perhaps it is soaking all the energy from its tail before altering its trajectory??
As always......you decide!

According to this guy the thing behind ISON is a star.
ISON is moving off its projected track, probably due to the large jet coming out of it, and no pictures from Hubble have been released since July !!!
Frances, the link below might be useful for your forage into astronomy.

The total brightness of the comet within a 0".24-diameter aperture remained unchanged within 0.03 mag over the 19-hr observing window. Broadband photometry yielded Af(rho) = 1376 cm at 589 nm, and 1281 cm at 433 nm, consistent with a red slope of 5 percent per 0.1 micron for the coma dust. A well-defined jet is visible after removing the 1/r brightness distribution. The jet is centered on position angle 290 deg, with a cone angle of 45 deg, a projected length of 1".6, and a slight curvature towards the north near the end. No temporal change in the morphology is observed over the three epochs, suggesting that the jet is circumpolar.
