NASA Cancels Hubble Mission, and Other Space Bits
An anonymous reader writes "NASA Watch is reporting that NASA has cancelled Servicing Mission 4 for the Hubble Space Telescope. The reason given is not for budgets, but for safety." ender81b writes "With all the excitement generated by the Mars Exploration Rovers now is a good time to look at future space exploration missions. One of the most exciting is the Kepler spacecraft which will search for terrestrial planets around nearby stars. Other interesting upcoming missions include the New Horizons mission to explore Pluto and the Kuiper belt, Deep Impact which will fire a small impactor into a comet to study the insides, Messenger which will fully photograph Mercury for the first time, and the ESA's Herschel infrared space telescope and Rosetta spacecraft which will land on a comet for the first time. Whew, good time to be invovled in space exploration!" StarWreck writes "Cnet.com is reporting that the Mars Rover uses Java. The same piece of software that lets people around the world play video games on their cell phones is now letting scientists drive the ultimate remote-controlled car across the surface of Mars."

I'm a space fan. I like manned space programs too. But they are going to wreck what NASA does do well, scientific research, for a program they will also not complete.
-pyrrho
Sir, we've run into a serious problem with the mission. These Nielsen ratings are the lowest ever.
Oh my God! We've been beaten by a "Connie Chung Christmas."
I'm laughing at clouds.
With all those links, you'd think maybe a Hubble link would surface... Here's a couple good ones:
Hubble For General Public
Hubble For Scientists

And, therefore, make a complete fool of themselves?
I can see the inevitable kneejerk reaction now. "OMG Bush is taking away money from science to fund his reelection he is evil."
Get A GRIP!
This was being considered before Bush's new proposal. It is not the fault of his proposal. And we are going to have a replacement put up. Nothing is being lost here, nothing is being sacrificed on the altar of MTMS, Man To Mars Soonest.
You killed Hubble! You bastard!
Anybody know what OS the rover uses?
MER2004 Mars Rovers use an OS by Wind River. Read about it at that link (press release).

we're not talking about especially complicated code in any case, so why bother with the overhead?
The rover isen't just a dumb remote controll car - NASA issues it rather sophisticated commands and the rover moves itself and decides on it own how to cary out those commands.
The reason for it is that Mars is too far away to manage the rover in real time - you have to wait 20 minuite to see the effects of your command.
Moneyed corporations, non-working 'poor' and criminal prisoners are turning productive citizens into tax-slaves.
NASA doesn't have that much money to play with anymore, and the hundreds of millions needed for another repair mission (even before the backup orbiter issue) was going to seriously screw up the timing of even getting the follow on telescope into the sky, not to mention the other robotic missions they're trying to keep alive.
Luke, help me take this mask off
Its a shell game. Bush announces new space plan: ' I hold a silver dollar in my hand'. Nasa immediately organizes and abandons hubble telescope mission. Nasa decides to abandon space station after completing it. Nasa decides to abandon shuttle replacement because the US wont be using the station after completing it and retiring shuttle Expect the following: To go the moon will require reinventing a rocket similiar to saturn 5 but at least twice the capacity. Money wont be found for this and that will kill the moon lander and mars landers. Nasa gets reduced by 1/2 or 2/3rds and will only launch small robotic vehicles to moon and mars. After awhile Nasa can't get budget for even those, because we've been there and done that. End of Nasa. End of US space program. Year 2012.
If anyone's curious about the CPU used by the rovers, it's one of the POWER derived radiation hardened chips made by BAE Systems. While it's PPC based, it's more similar to a family of CPUs that split off even before the first of the Mac PPCs, the 601. Similar operating speed and power, however, as the first of those.
The newer PPC based space capable CPUs are RAD750s, which are directly related to the G3 PPC powering iMacs and iBooks.
While on the topic of space hardware, and going back to photograph mercury, what kind of camera equipment was used to take images of the moon and mars in the 1960s/1970s? I was told by an English teacher that each photo was snapshotted on film, then exposed in a small photoprocessing lab inside the probes, and scanned to send back to earth as there was no possibility of capturing fast moving images on CCD that far back. I think that sounds a bit of wishful thinking urban legend. Anyone know for sure?
thanks
It seems like it is just an excuse from the head of NASA, who was a beancounter, alone. Perhaps the most tragic thing was that Columbia was lost while on a purely-for-science mission.
The thing is, bang for bucks, Hubble must be at least two orders of magnitude above the ISS in returning scientific data. It would not have costed above 10billion, compared to the hundreds of billions the ISS sucked up, and it had given us little, or next to nothing scientific data. No permanent scientific crew, the Destiny science module not being put to good use because the barebone crew of two is too preoccupied running it. All it stands for is an ego booster - we have a permanent manned presence in space, albeit a skeletal crew stuck for years in low Earth orbit, forever tied down doing endless plumbing just to keep it there.
I am starting to doubt if we will see a Hubble successor. And the sad fact is that we will not be fully realising the potential of Hubble, a good piece of hardware that had inspired and impressed so many of us at such a bargain price of under the cost of a B2 bomber.
We're thinking of sending someone to mars, but that Hubble thing--WAY too dangerous!

Hmm, Java.
Slight clarification, after re-reading the link I just posted:
/.)
The Americans used pretty standard television technology for their cameras. The Russians developed a slightly different technology - still based on the 'cathode/anode tube thingy' idea, but with more sensitive equipment and a pan-n-scan technique for sending photos back. The cathode tube thingy (Photoelectron Multiplier Tube) would scan across the photo film, so that the entire image could be scanned a piece at a time, and with better clarity.
Read the above link for more info, it's pretty cool stuff. The site has quite a bit of interesting information on the Russian space program, including some enhanced and reprocessed images of Venus (previously seen on
If I was worried about Karma, I'd eat tofu.
1. NASA already has Hubble's replacement telescope in line for 2011.
2. NASA will be able to operate the Hubble until 2007 or 2008.
3. There are a limited number of shuttle launches possible before 2010 when the station is complete. NASA needs to spend those launches on finishing the station, not upgrading a telescope that is being replaced, just so it can last a few extra years.
4. Since the Columbia disaster, non-station trips require TWO shuttles prepped for every ONE launch, so that there is a rescue shuttle available. That is a tremendous waste of resources for upgrading the Hubble, which is being replaced in any case.
In sum: The Hubble is being replaced in 2011 with an improved space telescope, so it is a waste of limited resources (shuttle launches) to upgrade it just to drag out its lifetime by three years or so. The time and energy saved from not upgrading Hubble can be spent on getting other projects done.
Hubble was great. It's lifetime is over, and it has lasted longer than scheduled. Time to move on.
And it mostly hurts the Goddard Space Flight Center and the Space Telescope Science Institute, both of which are located in solidly Democratic Maryland.
NASA is not going to die. Most people seem to forget that NASA stands for National Aeronautics and Space Administration. There's an awful lot more going on than a few robotic probes and shuttle launches.
What is abundantly clear, however, is that Bush's "space initiative" is nothing more than smoke and mirrors designed to boost his approval ratings. Let's crunch a few numbers: Bush's plan set aside an additional $12 billion for developing a "Saturn Mark II" launch vehicle with a capsule capable of landings on both the Moon and Mars. Not only is the number ridiculous, but so is the method for obtaining the funds. Bush claims that $1 billion will be allocated by Congress, and the additional $11 billion will be found by restructuring NASA, including ending shuttle flights. So we'll finish up the station by 2010, auction the shuttles on eBay, and be on the Moon by 2015? Riiiight. First of all, NASA won't have any free funds from ending the shuttle program until at least 2010 when the station is complete, and then that only leaves 5 years for development of a completely new vehicle and support system. Even then, the shuttle's budget is only about $4 billion. The remaining $7 billion will have to be earned by cutting into NASA's remaining $11 billion. So once again, the Aeronautics branch of NASA is getting the shaft in favor of a bloated and fatally optimistic manned space program. Sound familiar? It's the shuttle all over again.
Since the federal government seems to be waffling on what it thinks NASA should be doing, I am in favor of a much less glamorous "bottom-up" approach to space exploration. Let the private entrepreneurs build simple craft to get us barely out of the atmosphere. From there, the craft get slightly more sophisticated, and through the magic of technological evolution from several sources, we end up exploring the solar system in ways we can't even dream of now. We can parallel this growth to that of the internet: it started as a large, well funded government program (ARPANET), but it wasn't until the little guy started to find commercial opportunities that it really took off (Amazon, anyone?) If we had relied on the DoD to create the internet for us, we'd be stuck with an online copy of the Library of Congress, distributed through a huge router the size of a steel factory and transmitting over a 9600 baud connection.
While Bush has his head in the sand, the X-Prize and the X-Prize Cup will be ruling the upper atmosphere! I plan on retiring at the Shady Craters Lunar Resort.
And, to keep this little tirade on topic:
The Hubble Telescope has performed beautifully and well beyond its intended lifespan. There are other, better space telescopes in the works. Let's save the shuttle flight for station hardware and let the telescope retire with dignity.

The Hubble is being replaced in 2011 with an improved space telescope, so it is a waste of limited resources (shuttle launches) to upgrade it just to drag out its lifetime by three years or so.
The Next Generation Space Telescope, now called the James Webb Space Telescope (first time NASA's named a scientific instrument after an administrator) is not a replacement for Hubble.
Its an infrared optimised 6ish m telescope (downscoped from 8m). It has little optical capability, no UV capability. Its an extension to what Hubble can do not a replacement. There is much excellent stuff that JWST will be able to do, but there is much that Hubble can and could do in the future that JWST cannot. Indeed there has been a lot of debate about keeping HST running so that it can operate concurrently with JWST filling in the missing parts of the spectrum for the new telescope as well as continuing with its own excellent work. The synergy would have been excellent.
To suggest that JWST is a straightforward replacement for HST is very wrong, and demonstrates a complete misunderstanding of the capabilities of the two instruments. Do check your facts first.
