NASA Loses Contact With Comet Explorer
linuxwrangler writes: "According to this article in the SF Chronicle, NASA lost contact with the Comet Nucleus Tour ('Contour') satellite just after firing engines to boost it out of orbit. The spacecraft was launched July 3 with the mission to probe comet Encke in 2003, Schwassman-Wachmann 3 in 2006 and perhaps d'Arrest in 2008.
NASA is calculating possible trajectories in an attempt to search for and contact the probe.
Let's hope they regain contact/control. This sounded like a cool project." Liquor adds: "The BBC has a report that indicates that the launch window for the $159M spacecraft closes tomorrow. If it hasn't successfully fired the engine by then, it can't make the planned mission."
Does anybody know what self correcting mechanisms to contact NASA or meet the launch window, or anything else, that the probe has?
of taxpayer money,"Flying out the window"....
I never spellcheck and I freely admit it. Save your karma for more worthwhile "lol erorrs" replies
They find it collecting dust samples on Mars.

Am I the only one getting sick of NASA constantly screwing up? They say they arent getting enough money but it seems as if they are wasting the money they do get on mishap after mishap, you would think that they would realized that if they stopped screwing up, and wasting our money that maybe they would accually be able to convince congress to give them a larger budged. I dunno, over all I like NASA they just are pissing me off as of late.
Just my 2 cents.
...that NASA should be eliminated. Not only are the Space Admins stifling free-market efforts towards space, but they are also bungling fools who mess up English to Metric conversions and throw satellites into space without thoughts towards back-up comm methods. I mean, shite, dude, even Amateur Radio guys know that if you're dealing with something important, you have a second method of communication.
If, back after we landed on the moon, we switched to subsidizing private Space Exploration rather than feeding mega-Trillions to NASA, we'd already have our colonies on the damned moon, and we'd probable have it for alot less than what NASA's blown on the Space Shuttle program alone.
From the Apollo 1 to Apollo 13 to Challenger to this day, NASA's proven itself to be an organization that is all too self-aware of their job security.
Only in slashdot are posts of solidarity modded at -1 Redundant, while posts of antagonism are modded as -1 Flamebait.
The cost-saving plan was to boost it into space using an onboard Star 30 solid rocket motor this morning. The approach shaved $10 million off the cost of the mission, compared to a plan that would have shot the craft directly from launch to deep space. Buckley told SPACE.com there are two scenarios for what might have gone wrong:
$10 million well saved, boys!. Now they've blown the whole $159 million. Hope they got more than this to put on their resume, they're gonna need it.
Turns out there was a 1 gram misbalance caused by SOME GUYS ASHES in an old film cannister, glued to the wing...

Here's the latest press release from the CONTOUR people, which can be found here:
CONTOUR: Latest News
August 16, 2002 -- 1 p.m. (EDT)
Search for CONTOUR Continues
Mission operators continue to listen for a signal from CONTOUR.
Using its 34-meter antennas, NASA's Deep Space Network stations are scanning the spacecraft's expected path beyond Earth's orbit, attempting to pick up radio signals from CONTOUR's transmitters. The CONTOUR team is also awaiting feedback from several NASA-sponsored and other optical and radar sites that have been searching the skies for signs of the spacecraft.
CONTOUR's STAR 30 solid-propellant rocket motor was programmed to ignite at 4:49 a.m. EDT on Aug 15, boosting the spacecraft out of an Earth parking orbit and onto a trajectory to encounter two comets over the next four years. The spacecraft was too low for DSN antennas to track it during the burn - about 140 miles (225 kilometers) above the Indian Ocean - and the CONTOUR mission operations team at the Johns Hopkins University Applied Physics Laboratory expected to regain contact about 45 minutes later to confirm the burn. No signal was received, and the team has been working through plans to find the craft along the predicted trajectories for a successful burn.
CONTOUR's onboard computer was carrying a command that, starting at 6 a.m. EDT today, would have turned the spacecraft and pointed another of its four antennas toward Earth. So far, however, no signal has been received.
CONTOUR, a Discovery-class mission to explore the nucleus of comets, was built and managed by the John Hopkins University Applied Physics Laboratory, Laurel, Md., for NASA. Additional information about CONTOUR is available on the Internet at: http://www.contour2002.org.
They aimed a telescope at the position where it is expected to be, and they found what appears to be TWO moving spots instead of one.

Not a good sign.
Here is an image that appears to be a positive/negative overlay to help seperate star images from moving things:

There are 4 streaks here because there are two sets of positive/negative plates overlapped I am speculating.
Table-ized A.I.
Everytime I go to space.com my browser goes haywire, but in different ways each time.
They did an overhaul recently and it has not been the same since. I will take functioning over pretty any day.
They have too much JavaScript, Flash, and pop-up ads.
Somebody over there needs to be FIRED now!
Burn The Fuckholes!!!!!!!
The complexities of launching such a craft are phenomenal. And I imagine this mission just suffered from one of many potential problems that could occur. I can accept that.
That being said, what if they took our 500 million and then sent up a couple of cardboard boxes, how would anyone ever find out, short of going out there and looking at the stuff first hand?
Now, if there were different times I'd never even consider such a scenerio. But in the context of our times it would be illogical to not consider such things. I find it tragic to be living in times when such suspicions are prudent.
