t's been twenty years since the Hubble Space Telescope (HST) was launched on April 24, 1990. The Connecticut Post has a really nice article describing how the engineers who designed HST still remain emotionally attached to the project.

As is well known, when the first images arrived from HST, it was discovered that the primary mirror was flawed. The flaw was caused because of an error in the reference optics used by Perkin-Elmer to test the mirror. Rochester, NY has two notable connections to fixing this problem. First, Eastman Kodak's Commercial and Government Systems Group (now a part of ITT Space Industries) had independently manufactured a back-up mirror for the HST. Unfortunately it was not feasible to replace the primary mirror while the HST was in orbit. Second, Jim Fienup (now a professor at the University of Rochester Institute of Optics) developed "phase retrieval" computer algorithms that were able to diagnose and digitally correct the images Hubble was sending back. This information was later helpful in designing the Corrective Optics Space Telescope Axial Replacement (COSTAR) that was added to Hubble to correct the spherical aberration.

The Giants' Shoulders (originally organized by a colleague over at Skulls in the Stars) is a monthly event in which bloggers from a variety of disciplines and backgrounds all write about science history on the same day (more or less). It's always an interesting read, and this month it's hosted at The Lay Scientist. You can see a list of the articleshere.

Peter Emmel just notified me that the White House has put forth a request for information (RFI) for new "Grand Challenges" for the 21st Century. In essence they are soliciting ideas for a new "Moon Shot." There are no formal formatting instructions, and anyone can participate. It is essentially a public opinion poll on how research dollars will be spent... So speak up! The main PR site is here, but more detailed information is available from the original press release.

I wanted to point people toward a really good article that appeared in the SPIE Professional back in October 2009 entitled "Productive Stupidity" by Martin A. Schwartz. It's a reprint of his article "The importance of stupidity in scientific research", which previously appeared in Journal of Cell Science 121, 1771 (2008). The thrust of the article is that "science is supposed to be hard," and most of the time you're going to be wrong... at least if you're doing it right. That fact can be extremely difficult to accept, especially when we have built our entire education system around getting answers "right" on an exam. Even classroom laboratory research is generally focused on reproducing a certain result, rather than self-discovery. The upshot is that most science students leave college still believing that getting the "wrong" result is bad. If you are truly doing new research, then you are testing things that no one has done before, and that means that most of the time what your experiments reveal will not be quite what you expected. Figuring out the how and the why of unexpected results is what scientific research is really all about. (As Celia recently discovered over at Ph.D.) And just to drive this point home one more time, I encourage folks to listen to this interview with 2009 Physics Nobel Laureate George E. Smith. Around the 11 minute mark he talks about what it was about the Bell Labs environment that made their discovery of the CCD camera possible. He summarizes it this way:

In the exploratory efforts we had... we thought that if half of the projects you started actually worked, you weren't being imaginative enough... not taking enough risks.
