The Deep Space Climate Observatory has resumed regular observations after NOAA and NASA engineers uplinked a software patch to the spacecraft a million miles from Earth, restoring data on space weather and a daily series views of the sunlit side of our home planet.

LISA Pathfinder success bolsters plan for gravitational wave observatory

June 8, 2016 Stephen Clark

Europe’s LISA Pathfinder mission — a fundamental physics lab launched last year to a point a million miles from Earth — has demonstrated the mind-boggling technology required for a future space-based observatory to listen for faint, low-frequency vibrations emitted by invisible objects in the most distant pockets of the universe, scientists said this week.

European probe blasts off on gravitational wave demonstration

December 3, 2015 Stephen Clark

A solid-fueled Vega launcher fired through a low cloud deck and sped into orbit from the South American jungle early Thursday with a pioneering European spacecraft that marks a key step in a century-long quest to detect elusive gravitational waves predicted to permeate the cosmos.

Vega booster crowned with gravitational probe pathfinder

After criss-crossing Europe for a decade, the LISA Pathfinder satellite testbed has reached its last stop before launch in early December on a mission to demonstrate the delicate technologies required to detect elusive low-frequency gravitational waves rippling through the cosmos.

Launch campaign begins for Europe’s trailblazing gravity probe

October 12, 2015 Stephen Clark

A compact European space probe, already fitted with a propulsive boost stage to send it a million miles from Earth, has arrived at its French Guiana launch base for liftoff in early December aboard a solid-fueled Vega rocket.

DSCOVR space weather sentinel reaches finish line
