During a fourth spacewalk Saturday to wrap up repairs of the coolant system in a $2 billion cosmic ray detector, Italian astronaut Luca Parmitano and Drew Morgan discovered a leak in one of eight coolant lines that were spliced into a new pump module during three earlier excursions. But Parmitano was able to tighten a fitting on the line and the astronauts were able to complete the repair work, setting the stage for the instrument to resume science operations.

SpaceX releases preliminary results from Crew Dragon abort test

January 23, 2020 Stephen Clark

Data from the Jan. 19 in-flight launch escape demonstration of SpaceX’s Crew Dragon spacecraft indicate the performance of the capsule’s SuperDraco abort engines was “flawless” as the thrusters boosted the ship away from the top of a Falcon 9 rocket with a peak acceleration of about 3.3Gs, officials said Thursday.

Atlas 5 for Solar Orbiter launch returns to assembly building for inspections

January 22, 2020 Stephen Clark

United Launch Alliance moved its next Atlas 5 rocket off its Florida launch pad Wednesday for inspections after a cooling duct unexpectedly disconnected before a planned countdown rehearsal to prepare for liftoff next month with the joint U.S.-European Solar Orbiter mission. The roll back to the Vertical Integration Facility at Cape Canaveral’s Complex 41 launch pad could delay Solar Orbiter’s liftoff, which was scheduled for Feb. 5
