Latest Planck Stories
Last night, the detectors of Planck's High Frequency Instrument reached their amazingly low operational temperature of -273Â°C, making them the coldest known objects in space.
Beginning today, ESA's Planck satellite will carry out a critical mid-course maneuver that will place the satellite on its final trajectory for arrival at L2, the second Lagrange point of the Sun-Earth system, early in July.
The European Space Agency says the commissioning of scientific instruments and subsystems aboard its Herschel and Planck spacecraft has started. The two space observatories were lifted into orbit aboard an Ariane 5 rocket last week from the French spaceport at Kourou, French Guiana.
After a perfect injection by the Ariane 5 launcher on May 14, the critical Launch and Early Orbit Phase (LEOP) for Herschel and Planck has started to wind down, while commissioning of the scientific instruments and subsystems on both spacecraft has begun.
The European Space Agency's Herschel and Planck satellites went into space Thursday aboard an Ariane 5 rocket from the French spaceport in French Guiana. The dual space telescopes were headed toward a spot called L2 -- the second Lagrange point -- where they will operate in different orbits. L2 is a local gravitational point that is fixed in the Earth-sun system and is situated on Earth's night side, the ESA said.
Ground crews at Europeâ€™s Spaceport in French Guiana celebrated the successful tandem launch of the Herschel and Planck satellites aboard an Ariane 5 ECA heavy rocket on Thursday.
The European Space Agency says the Ariane 5 rocket that will carry the Herschel and Planck satellites into space has been declared ready for launch. The Arianespace declaration followed a Saturday launch readiness review and a final close-out review conducted Tuesday. Liftoff is scheduled for 9:12 a.m.
There's a buzz in the Main Control Room as the launch of Herschel and Planck gets closer. The two satellites are scheduled to launch together at 15:12 CEST, May 14, on an Ariane 5 from ESA's Spaceport in Kourou, French Guiana. Several critical events are planned leading up to and after launch.
The European Space Agency is gearing up for this monthâ€™s launch of two of the most sophisticated astronomical spacecraft ever built, the Herschel and Planck telescopes.
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.
Wilkinson Microwave Anisotropy Probe (WMAP) -- The Wilkinson Microwave Anisotropy Probe (WMAP) was launched on June 30, 2001 at 3:46 p.m. EDT at Cape Canaveral Air Force Station, Florida, USA. The goal of WMAP was to map out minute differences in the Cosmic Microwave Background (CMB) radiation which would help test theories of the nature of the universe. On February 11, 2003, the public relations group from NASA made a press release regarding the age and composition of the universe....
