NASA reports ESA’s LISA Pathfinder Spacecraft powered down

NASA - National Aeronautics and Space AdministrationPasadena, CA – With the push of a button, final commands for the European Space Agency’s LISA Pathfinder mission were beamed to space on July 18th, 2017, a final goodbye before the spacecraft was powered down.

LISA Pathfinder had been directed into a parking orbit in April, keeping it out of Earth’s way. The final action this week switches it off completely after a successful 16 months of science measurements.

While some spacecraft are flashy, never sitting still as they zip across the solar system, LISA Pathfinder was as steady as they come — literally.

NASA reports LISA Pathfinder Mission tests technology for detecting Gravitional Waves

NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MDLISA Pathfinder, a mission led by the European Space Agency (ESA) with contributions from NASA, has successfully tested a key technology needed to build a space-based observatory for detecting gravitational waves.

These tiny ripples in the fabric of space, predicted by Albert Einstein a century ago, were first seen last year by the ground-based Laser Interferometer Gravitational-Wave Observatory (LIGO).

Seismic, thermal and other noise sources limit LIGO to higher-frequency gravitational waves around 100 cycles per second (hertz).

NASA’s LISA Pathfinder spacecraft thrusters pass their functional tests

NASA - National Aeronautics and Space AdministrationPasadena, CA – While some technologies were created to make spacecraft move billions of miles, the Disturbance Reduction System has the opposite goal: To keep a spacecraft as still as possible.

The thruster system, managed by NASA’s Jet Propulsion Laboratory, Pasadena, California, is part of the European Space Agency’s LISA Pathfinder spacecraft, which launched from Kourou, French Guiana on December 3rd, 2015 GMT (December 2nd PST).

LISA Pathfinder will test technologies that could one day allow detection of gravitational waves, whose effects are so miniscule that a spacecraft would need to remain extremely steady to detect them.

NASA Thruster system aboard LISA Pathfinder spacecraft

 

Written by Elizabeth Landau

NASA - National Aeronautics and Space AdministrationPasadena, CA – The LISA Pathfinder spacecraft is on its way to space, having successfully launched from Kourou, French Guiana (December 3rd local time/December 2nd PST). On board is the state-of-the-art Disturbance Reduction System (DRS), a thruster technology developed at NASA’s Jet Propulsion Laboratory, Pasadena, California.

LISA Pathfinder, led by the European Space Agency (ESA), is designed to test technologies that could one day detect gravitational waves. Gravitational waves, predicted by Einstein’s theory of general relativity, are ripples in spacetime produced by any accelerating body.

The LISA Pathfinder spacecraft, which launched on Dec. 3, 2015, from Kourou, French Guiana, will help pave the way for a mission to detect gravitational waves. (ESA)
