Hubble Telescope's Main Camera Shuts Down
anthemaniac writes "Space.com is reporting that the aging observatory's primary camera, the ACS, has been in safe mode since the weekend. From the article: 'An initial investigation indicates the camera has stopped functioning, and the input power feed to its Side B electronics package has failed.' The camera has shut down before and been revived."

No wonder they can't contact it. Safe Mode doesn't support networking by default.

Truly spoken like an ignorant retard. Or a troll, in which case I'm falling for it. This "POS" is one of the greatest astronomical instrument ever devised, and has yielded enough data for years of study to come. There's a reason why scientist want to keep it around.

Engineering is the art of compromise.
why waste it in such a fashion. The shuttle is designed to retrieve it. how much could the smithsonian get for having that on display.
That would be a good thing for Nasa to do.
i thought once I was found, but it was only a dream.
There's one more Hubble repair mission to come (planned for Atlantis's final flight).
And despite future spacecraft like JWST, none of the planned replacements will cover the UV range.
RTFA: It was restored from safemode on Sunday -.-
They are hoping to switch it back over to the primary power supply and get limited usage until the shuttle gets there.

Dear Troll,
The HST Data Archive (HDA) has always been available to the public, albeit after a one-year "proprietary rights" period.

It shorted, and burned enough plastic or wiring to trip the overpressure sensor (do wire shorts smell in space?). See this message from the Space Telescope Science Institute. Side A electronics are available which might be able to run a portion of the instrument. This has been expected since the first failure last summer, and "contingency" proposals are available to keep the observatory running using its other instruments (ACS has recently been the most used).
Eh? In case you're actually serious about this, (a) The US demonstrated ASAT capability over 20 years ago, and (b) ASAT capability is completely irrelevant, as such attacks don't deorbit the satellite, but result in tens of thousands of pieces of debris that are dangerous to other satellites.
In any case, casting aspersions on NASA's ability based on Hubble is ridiculous, as it's been by any measure a spectacularly successful instrument, which even 17 years after launch has capabilities not matched by any foreseeable ground-based instruments (no, not even with adaptive optics) or by any planned space instrument.
The Advanced Camera for Surveys wasn't installed until the third servicing mission in 2002. It's been problematic since then. If it can be installed on a spacewalk, it can be replaced on a spacewalk.
Also, the Hubble servicing mission has been approved. Barring some act of God or Congress, Atlantis will conduct this mission on STS-125 in May of 2008. The ACS was not on the itinerary for service, but it might still be possible to add it to the agenda or push back the mission date if need be. On the other hand, it might be possible to work around whatever problem caused the latest shutdown, the third according to Wikipedia.
I should point out the foot dragging was largely spurred on by calls for the retirement of the shuttle as soon as possible (even immediately) and some general hysteria following the Columbia incident (as opposed to the rational re-examination that also took place). There is also the issue of the cost, which is in the range of hundreds of millions and had not been provided for, and a difference of philosophy between O'Keefe (administrator until 2005) and Griffin (current admin). Mission development is fully provided for in 2007, and should be in the 2008 budget, too.
If Hubble was going to roll over and play dead, it should've done so back in mid-2005, before more money had been spent on the servicing mission.
The parent is not informative, it is wrong, or at least out of date.
The Space Shuttle will be retired upon completion of the ISS. NASA will be taking steps over the coming years which would prevent almost any extension of the currently planned flight schedule, like reconfiguring launch pads to support the future vehicles, retiring shuttle craft as they complete their scheduled missions, caniballizing said vehicles for parts, and refraining from ordering parts like external tanks and solid rocket boosters which would be required to extend the schedule by even one flight.
The shuttle will cease operations regardless of the status of replacement vehicles. Although many planned technology programs intended to help replace the shuttle with a more reliable and cost effective system were cancelled over the years, NASA is currently pursuing a manned vehicle program, Orion which has not been cancelled.

I am still miffed after reading another story elsewhere about what we pay football coaches versus what we pay the president of the college.
We'll get what we pay for. Maybe the average American feels tougher football games are more important to our society than scientific research.
Most do not want to take the time to study science... but in the end, its the laws of nature ( applied science ) that will determine the temperature of my house, the operation of my car, and whether or not I eat. In short, my whole life is determined by my and other's knowledge of applying science.
Maybe pretty pictures of the stars isn't deemed particulary useful. The pictures are only the frosting. The important thing to me is gaining more and more understanding of materials and physics governing them. Technologies developed are useful for many things, especially medical and agricultural.
I feel that as an intelligent species, it behooves us to understand the universe around us and our place in it. By observing phenomena happening somewhere else, it will help us to intelligently react if it happens to us.

Jargon alert for non specialists: ACS = Advanced Camera for Surveys; WFC = Wide Field Camera; HRC = High Resolution Camera; SBC = Solar Blind Channel; CCD = charge coupled device; WFPC2 = Wide Field and Planetary Camera 2 (an older instrument); STScI = Space Telescope Science Institute; and GSFC = Goddard Space Flight Center.

Only Me (A Hubble Tribute)
To the tune of "Only you"
By Joel Gilmore, 2007
Looking at the sky up above
Taking photos with love,
Can you fix me?
Found out only yesterday,
my orbit's soon to decay
Can't you boost me?
Chorus:
All I needed was a manned space flight
All I needed for another night
Since 1993 -
only me.
If I lose one more gyroscope
I don't know if I'll cope,
Send Discovery!
Install Wide Field Camera 3,
Spectrograph, batteries,
My camera's dying!
Chorus:
All I needed was a manned space flight
All I needed for another night
Until James Webb, there'll be -
only ME!

Neither can Hubble. The Hubble Deep Field was pieced together from 10 nights of images. The newer Hubble Ultra Deep Field, from 11 nights.
Pretty much any half-decent-looking astronomical image you see is a combination of multiple exposures. I'm one of the operators of the 2.2-meter (that's slightly smaller than Hubble) telescope on Mauna Kea, and have been teaching myself the process of getting and combining images in different filters/wavelengths. For example, I made this shot of M76 from about a dozen exposures. (Using, incidentally, the same instrument that was used to discover the Kuiper Belt back in 1992.)
Just a data point.
Village idiot in some extremely smart villages.
I work at STScI and it sounds like they're going to be able to switch ACS back to the side 1 power supply. Unfortunately, it means that the WFC which is the most used won't be working. A failure of the side 1 supply to WFC is why they had to switch to side 2 this summer.
The good news is that WFPC2 is still working even if it doesn't have the imaging area or sensitivity of ACS. The telescope allocation committee just re-opened applications for next cycle so lots of people are just going to switch their proposals from using ACS to using WFPC2 (myself included). As a side note: anyone can apply for telescope time since its run with taxpayer money. Just go to the site and fill out the form.
The other good news is that the servicing mission is going ahead for early 2008 when they're going to put in WFPC3 which is a bit better than ACS and will have much lower distortions and a great new spectrograph called COS. That'll take HST to the end of its life in 2013. At that point, the next space telescope, JWST, will be launched. In case you're wondering though, JWST will have a much shorter life since it won't be possible to service it.
So yeah, it sucks that ACS smoked itself but it's not the end of the world.
