US Panel Proposes Killing Webb Space Telescope

The House Appropriations Committee proposed Wednesday to kill the James Webb Space Telescope, the crown jewel of NASA’s astronomy plans for the next two decades. Successor to the Hubble Space Telescope, and it was designed to study the first stars and galaxies that emerged in the first hundred million years or so after the Big Bang.

Astronomers reacted with immediate dismay, fearing that the death of the Webb telescope could have the same dire impact on American astronomy that killing the Superconducting Supercollider, a giant particle accelerator in Texas, did in 1993 for American physics, sending leadership abroad.

Canceling the Webb telescope would “have a profound impact on astrophysics far into the future, threatening U.S. leadership in space science,” said Matt Mountain, director of the Space Telescope Science Institute in Baltimore, which would run the new telescope. “This is particularly disappointing at a time when the nation is struggling to inspire students to take up science and engineering,” he added.

Despite this the good news is that the European Union is to head to the front of space technology with it’s incredible Gaia Spacecraft launching in 2012.  Its billion-pixel imaging sensor will be among the largest digital cameras ever to exist, and over the course of its mission, it’s estimated that Gaia will detect 15,000 new alien planets.


Gaia’s gigantic sensor is comprised of 106 separate CCD detectors, mosaiced together to form a monster camera over three feet wide. The resulting imaging system is so powerful that it will be able to precisely measure the width of a hair from over 600 miles away, and from here on Earth, it could spot a dime on the moon.
