LISA Pathfinder launch grounded to analyze Vega upper stage

December 1, 2015 Stephen Clark

Launch managers in French Guiana have delayed liftoff of a European gravitational probe pathfinder at least one day to study out-of-bounds thermal readings from the upper stage of its Vega rocket booster, officials said Tuesday.

Finely-crafted experimental space probe ready for launch

December 1, 2015 Stephen Clark

A modest European-built spacecraft tuned to test the delicate, cutting edge technologies required to detect gravitational waves, a measurement that scientists say could yield unforeseen discoveries about the universe, is awaiting liftoff aboard a solid-fueled Vega rocket this week.

ExoMars nears launch, thanks to nonstop work in factory

November 30, 2015 Stephen Clark

Working around the clock to meet a 12-day launch window in March, European engineers are putting the final touches on a Mars orbiter that could shed light on whether tiny microbes or geologic activity still linger on the barren planet.
