LISA Pathfinder Takes Major Step In Hunt For Gravity Waves
2011-11-14 10:44:11

Sensors destined for ESA´s LISA Pathfinder mission in 2014 have far exceeded expectations, paving the way for a mission to detect one of the most elusive forces permeating through space — gravity waves. The Optical Metrology Subsystem underwent its first full tests under space-like temperature and vacuum conditions using an almost complete version of the spacecraft. The results exceeded the precision required to detect the enigmatic ripples in the fabric of space and time...

A European team working on the LISA Pathfinder mission has completed an extensive series of ground tests on the spacecraft's optical payload. The tests successfully achieved - for the first time on a spacecraft instrument - the incredible precision that will be required to confirm the existence of gravitational waves. The extremely precise measurements are realized by a laser interferometer that measures the distance between two free-floating heavy masses with reflective surfaces. In the...

Flight-model units for the LISA Pathfinder spacecraft are undergoing a series of tests to determine their magnetic characteristics. The purpose of the tests is to ensure that the stringent magnetic cleanliness requirements of the LISA Pathfinder mission will be met. The LISA Pathfinder mission objective is to verify that a test mass onboard the spacecraft can be kept 'free-floating', subject to unwanted accelerations of less than 3Ö10-14 m/s²....

A stunning sapphire and gold casket is the latest addition to the LISA Pathfinder flight hardware collection. Designed to house the LISA Technology Package proof masses the casket is now undergoing experiment characterization tests in Italy. The 'precious' core of the LTP At the core of the LISA Pathfinder spacecraft resides the LISA Technology Package (LTP) which is designed to demonstrate the technology needed for the LISA mission. The LTP is composed of two vacuum containers connected by...

Word of the Day
  • Scandinavian punch made of claret and aquavit with spices and raisins and orange peel and sugar.
This word comes from the Swedish 'glogg,' which is an alteration of 'glodgat,' mulled (wine).
