Hubble Repair Mission More Risky than You Would Ever Imagine
Posted by Jesus Diaz at 9:00 AM on September 7, 2008
If you think that the final mission to service the Hubble Space Telescope is going to be boring, you haven't seen this video yet. Not only the astronauts will be risking their lives as usual at 590km above the Earth, but the sheer amount and the difficulty of the tasks--from repairing components to replacing them to installing new gadgets--makes the mission an almost-impossible one, with soundtrack to match. I never imagined this was going to be such an ambitious and daunting work.
First, there's the pressure the astronauts are going to be facing. In addition to the stress of the spacewalks and the manual work in a weightless environment, they know this is not only the final mission, but also a single shot to service the mighty telescope. If some of the tasks are not completed, there's no way to return back another time and fix whatever is broken. The mission crew knows that Hubble is a vital instrument to science--one that keeps expanding our knowledge of the Universe, helping to answer the most crucial question Humanity has ever faced: where the hell do we come from?--and that the astronauts are men and women of science. And they are going to be the ones responsible for giving science this amazing tool for ten more years.
Then there's the time constrain: just eleven days. As John Grunsfeld--one of the mission astronauts with Andrew Feustel, Gregory Johnson, Megan McCarthur, Michael Good, Scott Altman, and Michael Massimino--puts it: "We got a lot of things we want to repair in Hubble and upgrade in Hubble, and not a lot of time to do it." During that short time, this is all the things they have to do:
Repairs
• Repair two failed instruments in space, which is the first time such a task is going to be attempted. This will be a test to see if Nasa can do this kind of tasks in future missions to the Moon and Mars. The repairs will require removing 110 (yes, a hundred and ten) little screws. While this seems easy, not only it will take a lot of time in zero gravity, but the screws, like any other floating debris, may become a big problem for the security of the astronauts up there.
• The first instrument to be repaired is the Advanced Camera for Surveys (ACS). It was installed in 2002, and then died after being the most used instrument in Hubble for years.
• Then they have to fix the Space Telescope Imagine Spectrograph (STIS). This is a black hole hunter which also did the first detection and chemical analysis of a planet orbiting another star.
New instruments
• They will install the fanciest, most advanced spectrograph in space: the Cosmic Origin Spectrograph.
• In addition to the COS, they are also going to install the Wield Field Camera 3. This new camera is ten times better than the current instrument, and will let us see into the past of the Universe deeper and farther than ever before.
Spacecraft service
• In addition to the pure science aspect of the mission, Nasa also wants to upgrade and fix the spacecraft itself, starting with the gyroscopes, which will be upgraded.
• They also are going to install a refurbished fine guidance sensor.
• The batteries are going to be replaced for the first time since Hubble went into space.
• A new outer blanket layer, this time a solid shield, will be put on top of the current blanket.
• Thermal insulation will be replaced on several bays of the telescope.
• A new capture instrument will be installed to recover the Hubble at the end of its life.
Seems like a lot to me, but maybe is the Jerry Bruckheimerish soundtrack that makes it all more exciting. The really exciting part however, if the mission is completely successful, is that Hubble will be better than ever, ready for action for the next ten years. What does this really mean? Awesome eye candy for the next decade. And maybe showing to us that the origin of the Big Bang is really a huge bowl full of Froot Loops that went horribly wrong during one of God's breakfast.

@discounteggroll: Astronauts don't get enough credit. People fawn over pro athletes, but they couldn't name more than 2 active astronauts.
They're basically like world class racecar drivers who hold several advanced degrees. More parents should make these men and women familiar to their kids and not 90% of the pro athletes we see.

Sadly, they need more Bruckheimer-like promotion like this to attract the attention of Joe Average these days.

The "capture instrument" isn't used to recover Hubble, it's so that we can send up a robotic craft, attach it to Hubble, and then fly the two into the atmosphere to destroy them in a controlled fashion, euphemistically called "de-orbiting".

"Hello, NASA? This is Microsoft. We need you to go bring the Hubble back to Earth so we can refurbish it. You'll have the exact same telescope returned to you in a couple months."
"Screw that. The first time we did that, we clearly got someone else's Hubble returned to us, and the last time you sanded all of our logos off the exterior hull."

@badhatharry:
There's a dead power supply involved, and they did not foresee any need to replace or service it, so they just screwed it in and called it good. Everything else is a modular design, so you just pull Junk A out of Slot B and replace it with Part A and everything's fine.
I don't know if it popped up here or somewhere else, but I watched a video about a month ago where they were talking about this mission. They have a clear plexiglas shell that they're going to bond over the part they need to unscrew. Over every screw, there is a hole that's big enough to fit the screwdriver, but _NOT_ big enough for the screw to come out after (this is important as just one free-floating screw could eventually get inside the telescope tube and trash the mirrors). Once they have everything out, they have a modular replacement all ready to just slip back into Slot B without having to fuss around with all those screws. So it's just for that one system that they need to do a job that's probably going to be as arduous as any 2-3 other repair tasks combined.
@thisisasignin:
Can you guarantee that one of those 110 screws won't get knocked loose during the process? And if it does, can you find it again afterwards? The answer to that is why they're going with a plexi shield that'll just seal them all up in a contained space.

@dinsey: I think it's a shame that they aren't going to bring Hubble back to earth. After all it's been through.. after all the science it's provided.. after all of the ground break missions which help to establish the systems and proceedures that are going to be used in future space servicing missions.. What are we going to do? Yeah.. that's right burn it up.
You know, some things are worth saving, regardless of cost or RISK. When all is said and done, Hubble deserves and has earned the right to get put into the Smithsonian.
If NASA can't afford to bring it home, then start saving pennies and do it later. Don't de-orbit the Sattelite.. use the recovery coupler and attach a pusher motor to place Hubble in a Higher, stable orbit.

@Overheal:
It's all worthless unless you make a conscious choice to turn a repair mission into a retrieval mission. They'll be bringing back one (actually, 112, by my count) part of the Hubble telescope that could be put on display afterwards, but consider that any retrieval mission you might launch would necessarily bring up the question of why you didn't just turn it into a full-out repair mission and keep the thing working (where a future deorbiting mission could potentially be accomplished with an unmanned mission, and certainly wouldn't require the workhorse capabilities of a Space Shuttle mission). Would you rather have a shot at ten more years of Hubble images getting spread all over the internet, or a big honking museum display piece that only a handful of people will be able to enjoy? Keep in mind that the next space telescope will be infrared-only, while the Hubble will soon be able to handle infrared through ultraviolet. And you're assuming that the Space Shuttle is even capable of making a safe touchdown with that much dead weight in the payload bay. They're hauling 10.5 _tons_ of material up there, a fair chunk of which will be added weight on what's already a 12 ton beast (some dead/dying components will be removed and either deorbited, or returned to Earth in the payload bay). And they do already have the second Hubble optical mirror on display (the backup copy of the original mirror that wasn't designed correctly).
@badhatharry:
Yeah, I was kinda freaked out about the idea of removing and _reinserting_ all of those screws...in space. But that was a cool little video to catch. Unfortunately, I have no clue where to find it now, but I did track down this page, which explains the process in more detail. What it doesn't include, which the video did, is that this is probably the most dangerous part of the mission, as they'll be accessing electronic guts that weren't designed to be spacesuit-safe, so there's a real possibility that the astronaut's suit could get torn on a sharp corner or something. There's also the possibility that a screwhead could be stripped, rendering the entire panel unremovable.

The folks signing checks need to understand that we have to get the chops to do the stuff in space that's needed to move us up and out.
Those chops are going to be gotten doing stuff exactly like this.
My hopes are very high for this mission. Why?
Because it's a mission to keep doing science, to keep learning, to keep growing.
Not just some race to beat China to the moon. :/

Our astronauts are truly the best and brightest this country has to offer. I talk them up to my students at every opportunity.
De-orbiting Hubble seems a crying shame. What a coup it would be to someday bring it back for display in the Smithsonian Air & Space Museum!
Bad News: Such a recovery is decades down the road, if not a century.
Good news: Any device sent up to dock with and de-orbit Hubble could just as easily push it to a higher orbit that the telescope could stay in safely for a century, or longer.

We shouldn't be so sure this is the last mission to the Hubble. Presidents change, NASA directors change and congress may find it important to keep this thing running because even though it's old it can still make very important discoveries.
Yes new better telescopes will be put into orbit but that does not make the Hubble obsolete in any way. It's better to have two orbiting telescopes than one. There are many scientists that have studies to perform on the Hubble so the waiting lists must be planned years out.

@Kodai1:
They're going to have the Endeavour standing by on another launch pad, designated STS-400 (Atlantis launches as STS-125) to be used as a recovery vehicle for the crew in case there's a problem that's severe enough that they can't safely return in Atlantis.
@BiZarRroBALlmeR:
The Space Shuttle fleet is set to be retired in 2010, and without it another repair mission is highly unlikely. Of course, there's always the possibility that the Shuttle retirement might be delayed, should the next President feel it's worth keeping that program alive. Or he could ask for a replacement for the STS program to be initiated (which is what we really need).

Good for NASA for applying some marketing to a shuttle mission. I love following space missions of all kinds, but NASA usually makes the most exciting missions seem dry, bland and routine.
Adding some excitement and effectively communicating the risks and difficulties before the mission is the best way to keep the public interested and prepare them for the inevitable problems that crop up. Too often NASA diminishes possible risks and the media then highlight how "NASA screwed up again".
Hopefully this is part of a new trend to sell their "product".

Judging from the trailer, cocky John Grunsfeld is going to go all rogue space cowboy after hours forcing no-nonsense Michael Altman to risk his life rescuing him, meanwhile former Italian pr0n star Michael Massimino (make up your mind, is it massive or mini?) will be getting it on with Megan McCarthur, but she'll kick his ass out of the space hammock to suit up with Gregory Johnson and together they will rescue the Hubble with seconds to spare.
