Q&A with Sara Seager, deputy director of science on NASA’s TESS mission (members only)

Engineers at NASA’s Kennedy Space Center tasked with overseeing launches of scientific satellites and interplanetary probes will be responsible later this year for ensuring six major missions safely get into space over a span of a little more than six months, beginning with the launch of NOAA’s new GOES-S weather observatory on an Atlas 5 rocket March 1.

Two more roll-out solar arrays will ride a SpaceX cargo ship to the International Space Station this weekend, continuing a years-long mid-life station upgrade as NASA plans procurement of a final set of new solar wings to fully reinforce the lab’s power supply.

Japan’s Hitomi X-ray observatory, beset by an attitude control problem that has disrupted communications since March 29, may have shed one of its power-generating solar panels or deployable telescope in orbit and is spinning too fast to contact ground controllers, officials said.
