Herschel and Planck launch set for May 14
The European Space Agency says it has set the liftoff date for its twin satellites, Herschel and Planck, from Europe's spaceport in French Guiana.
The ESA said additional checks on the Ariane 5 ECA launcher have been completed, allowing Arianespace and ESA to schedule the launch for May 14.
The Herschel space telescope mirror will be the largest ever launched into space. Planck is designed to observe the cosmic microwave background.
The ESA has twice postponed the launch due to technical problems.
