Astronauts finish repairs to space station cosmic ray detector

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.

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

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

SpaceX test-fires rocket for next Starlink mission; launch date under review

Just one day after a mission from a nearby launch pad, SpaceX test-fired a Falcon 9 rocket Monday at Cape Canaveral Air Force Station ahead of the company’s next flight. Faced with extreme weather this week in the ocean recovery zone for the Falcon 9’s first stage booster and payload shroud, SpaceX said it was evaluating the best opportunity to launch the Falcon 9 with 60 Starlink broadband satellites.
