Hubble servicing mission 1 December 1993
WFPC2 installed…a bit too tightly!
Comet Shoemaker-Levy 9 impacts Jupiter in July 1994, and Hubble’s comeback story begins!
Advanced Camera for Surveys (ACS) was installed in 2002…and failed in 2007
Two Space Shuttles on the launch pad again: Hubble’s 5th servicing mission, and it’s “launch on need” contingency rescue mission…gulp!
“Launch on need” contingency…
a.k.a. the end of the Space Shuttle program
Date: Sun May 10 14:28 EDT 2009Subject: good fortune?
Greetings All,
Apologies in advance for the spam, but this one was too strange not to mention.
Yesterday (Saturday) I was out having dinner at P.F. Chang's with the family, about to drop off the kids with their grandparents -- my wife and I are flying down tonight to see the launch.
At the end of the meal, we all cracked our fortune cookies. On the flip side, as is often the case, each of us had a Chinese translation of a common English word. My wife had "salt"; my daughters had "cucumber" and "strawberry".
The flip side of my fortune was the translation of "Space Shuttle". Whoa.
Here's hoping it's *good* fortune.

Hubble Ultra Deep Field(HUDF) with WFC3 / IR
We utilize the newly-acquired, ultra-deep WFC3/IR observations over the HUDF to search for star-forming galaxies at z~8-8.5, only 600 million years from recombination. These remarkable data reach ~0.5 AB mag deeper than ever before, and now are an excellent match to the HUDF optical ACS data.
We present a sample of 16 robust z~7 z_{850}-dropout galaxies detected by the newly installed WFC3/IR camera on the Hubble Space Telescope. These remarkable data cover 4.7 arcmin^2 and are the deepest NIR images ever taken, reaching to ~29 mag AB (5sigma).

Mission Specialist John Grunsfeld: What always strikes me as being so incredible is that it's almost impossible to go into any K-12 classroom these days and not see Hubble images on the wall inspiring kids to do great things and maybe some of them to become astronauts some day and push our frontiers even farther.
President Obama: Well, I know that you've excited my 10-year-old and my 7-year-old. And they've got some images like that that they prize whenever we talk about space. And so, by allowing Hubble to continue on its journey, you've really allowed all of us to continue on our journey for growth and exploration. I do have to just, by the way, say, Captain, that you and Dr. Grunsfeld as Illinoisans, you know I've gotta give you a special shout out.
Atlantis: Well, thanks very much, my sister was just asking today to take a picture of Chicago as we went by. We were able to see it in the distance and take a picture so we can send that along as well.
President Obama: Outstanding. We'll I've gotta get a copy of that picture. Maybe I ... did you guys see my house? I'm trying to figure out if my lawn is getting mowed there. I haven't been back for a couple of months.
Atlantis: We'll have to point Hubble at it to see that.
A behind-the-scenes perspective on Hubble servicing, calibrations, and "first light"
The riskiest part of the recent Hubble servicing mission was the repair of the Advanced Camera for Surveys (ACS). Since 1998, Max Mutchler has been member of the ACS team at STScI, where he has been involved in calibrations, designing observing strategies, and analyzing images. He was involved with the first test images taken minutes after the astronauts completed the ACS repairs, and also the "first light" image of the barred spiral galaxy NGC 6217. He also worked on the Early Release Observations (EROs) for both ACS and the new Wide Field Camera 3 (WFC3), so he is often the first person to glimpse the raw images beamed down from Hubble. Max will share his perspective on the exciting series of events over the past few months, and help explain: why did it take 4 months to release the first new images!
Max Mutchler is a scientist who has been working on the Hubble Space Telescope for the entire 19-year mission, including the recent Space Shuttle servicing mission. As an expert on Hubble's cameras, Max has been involved in observations of some of the nearest and farthest objects in the universe, which notably includes the discovery of Pluto's moons Nix and Hydra. He is also a member of the Hubble Heritage team that has produced many of the most iconic images from Hubble, and he recently helped produce the first images from the newly-serviced Hubble.
