Garbage pallet jettisoned from space station will stay in orbit two-to-four years
NASA ground controllers sent commands to the International Space Station on Thursday for release of a 2.9-ton cargo pallet loaded with old batteries, the most massive object ever jettisoned from the orbiting outpost. The garbage carrier is expected to remain in orbit for two-to-four years before re-entering the atmosphere.

Stacking complete for SLS boosters
The twin 177-foot-tall solid-fueled boosters for the first flight of NASA's Space Launch System have been stacked inside the Vehicle Assembly Building at the Kennedy Space Center to await arrival of the rocket's cryogenic core stage, which is set for a second engine test on a firing stand in Mississippi later this month.

NASA astronaut joins Russian Soyuz crew for April flight to space station
NASA astronaut Mark Vande Hei, veteran of a 168-day stay in space in 2017-18, will join two Russian cosmonauts aboard a Soyuz spacecraft April 9 for a flight back to the International Space Station in a deal brokered through Houston-based Axiom Space, NASA and the Russian space agency announced Tuesday.

Rubins and Noguchi assemble solar array support fixtures outside space station

Launch companies, range teams reassessing Cape Canaveral weather rules
Launch companies and U.S. Space Force range officials at Cape Canaveral are reassessing long-standing weather rules, looking at beefing up rocket defenses against lightning, and considering strategies to prepare for two different launch windows on a given day to guard against weather delays, something SpaceX may demonstrate with a Falcon 9 launch early Thursday.

Component fatigue caused early shutdown of Merlin engine on last SpaceX launch
SpaceX has concluded fatigue on an engine cover caused one of the nine Merlin 1D first stage engines on the company's most recent launch to shut down early during ascent, leading to the loss of the booster during an offshore landing attempt in the Atlantic Ocean, an official said Monday.
