Two missions to study the cosmos, the Herschel and Planck spacecraft, are scheduled to blast into space May 14 aboard the same Ariane 5 rocket from the Guiana Space Center in French Guiana. The European Space Agency, or ESA, leads both missions with significant participation from NASA. "The missions are quite different, but they'll hitch a ride to space together," said Ulf Israelsson, NASA project manager for both Herschel and Planck. "Launch processing is moving along smoothly. Both...

The European Space Agency's Herschel and Planck spacecraft are fueled and awaiting launch, with U.S. scientists playing important roles in both projects. The twin spacecraft are to lift off May 14 aboard an Ariane 5 rocket from the Guiana Space Center in French Guiana. The missions are quite different, but they'll hitch a ride to space together, said Ulf Israelsson, NASA project manager for both Herschel and Planck at NASA's Jet Propulsion Laboratory in Pasadena, Calif. NASA said Herschel's...

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. Herschel and Planck have already been fueled with hydrazine. Planck's three-stage active cryogenic cooler, needed to keep its instruments at extremely low temperatures, has been filled with helium-3 and...

A University of Michigan astronomer says he will use the European Space Agency's Herschel Space Telescope to search for the precursors of life. Associate Professor Ted Bergin said many organic molecules that make up life on Earth have also been found in space. Bergin wants to study those chemical compounds to gain insights into how organic molecules form in space, and, possibly, how life formed on Earth. Bergin is a co-investigator on the Heterodyne Instrument for the Infrared aboard Herschel...

Now that additional checks on the Ariane 5 ECA launcher have been completed, Arianespace and ESA have set the launch date of Herschel and Planck for Thursday May 14. In the meantime, the preparation of the two satellites for launch continues flawlessly at Europe's Spaceport in French Guiana. Herschel and Planck have already been fuelled with hydrazine. Planck's three-stage active cryogenic cooler, needed to keep the instruments at extremely cold temperatures, has been filled with helium-3 and...

Tests conducted on Planck at Europe's Spaceport in Kourou, French Guiana, have confirmed that the satellite's subsystems work perfectly, and the helium dilution cooler tanks have now been filled. While the final clean-up continues, the solar array has been checked, the satellite has been integrated with its launcher adapter and fuelling is complete. The last of the system reference tests, of the telemetry and telecommand subsystem, was completed on 17 March. The tests, carried out over the...

About two weeks ago, Herschel was weighed to record its dry mass before the satellite was fuelled with 256 kg of liquid hydrazine. After switching it on to confirm normal function, engineers integrated the fuelled satellite with the Ariane 5 adapter. On 26 March, the satellite's weight was measured with reference to calibrated masses for maximum accuracy. After this it was moved to another building on the launch site to begin fuelling operations. Herschel fuels up Herschel will use its...

The European Space Agency on Monday announced a short delay of the Herschel and Planck telescopes to give ESA and Arianespace additional time to complete final and independent checks. Both Herschel and Planck telescopes were set to launch May 6, but ESA officials announced that date would be pushed back "due to an anomaly discovered during tests on a subassembly identical to the one on the Ariane 5 launcher," according to a press release. ESA added that both satellites are "in perfect...

Herschel's three scientific instruments have passed their functional tests and are 'good to go'. This marks another milestone in the steady progress being made in preparing the satellite for launch. All three of Herschel's instruments, the Spectral and Photometric Imaging Receiver (SPIRE), the Photodetector Array Camera and Spectrometer (PACS) and the Heterodyne Instrument for the Far Infrared (HIFI), underwent short functional tests to verify the health of the instruments after transport to...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
