The SLS (Space Launch System) rocket and Orion spacecraft for NASA’s Artemis II mission arrived at the Vehicle Assembly Building from Launch Pad 39B at approximately 8 p.m. EST Feb. 25, at NASA’s Kennedy Space Center in Florida.  While in the assembly building, technicians will troubleshoot the helium flow issue to the rocket’s upper stage, replace batteries on the rocket’s upper stage, core stage, and solid rocket boosters as well as service its flight termination […]

NASA is sharing the following information at the request of NASA astronaut Mike Fincke: “On Jan. 7, while aboard the International Space Station, I experienced a medical event that required immediate attention from my incredible crewmates. Thanks to their quick response and the guidance of our NASA flight surgeons, my status quickly stabilized. After further evaluation, […]

Human research, advanced robotics, and experimental workout gear filled the schedule for the Expedition 74 crew aboard the International Space Station on Wednesday. The orbital residents also continued packing a SpaceX Dragon with science experiments and space hardware for its departure on Thursday.

Editor’s Note: The launch director gave the “go” for rollback at 9:28 a.m. EST followed by first motion 10 minutes later. NASA’s SLS (Space Launch System) rocket and Orion spacecraft for the Artemis II mission began rolling off the launch pad at 9:38 a.m. EST, Feb. 25, at NASA’s Kennedy Space Center in Florida.  Rolling from Launch Pad 39B to the Vehicle Assembly Building at NASA Kennedy is expected to take […]

Update Feb. 27: The Rocket Lab suborbital rocket successfully launched Feb. 27, at 7 p.m. EST. Update Feb. 26: The next launch attempt for Rocket Lab is scheduled for Friday, Feb. 27, 4-7 p.m. EST. Update Feb. 25: Rocket Lab is standing down from a launch attempt Wednesday, Feb. 25. The next launch attempt will […]

Plants exposed to artificial lighting burst into bloom earlier and flower longer than plants exposed exclusively to natural sunlight. A recent study that relies on NASA satellite data found that this effect raises pollen counts throughout much of the year, extending and intensifying allergy seasons in brightly lit communities. In a study in PNAS Nexus, […]

NASA is targeting approximately 9 a.m. EST, Wednesday, Feb. 25, to begin rolling the SLS (Space Launch System) rocket and Orion spacecraft for Artemis II off the launch pad and back to the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida. Teams will continue to monitor winds and temperatures in advance […]

The Expedition 74 crew will finalize the packing of a SpaceX Dragon spacecraft as it nears its departure later this week. Science operations were still underway aboard the International Space Station on Tuesday as the orbital residents explored how living and working in weightlessness is affecting their bodies.

NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite, known for measuring tiny organisms in the ocean and particles in the atmosphere, has a new capability: it can track nitrogen dioxide pollution. Nitrogen dioxide is a harmful air pollutant produced from burning fossil fuels and wood. The trace gas can also react with sunlight and oxygen […]

Due to weather, NASA now is targeting early Wednesday, Feb. 25, to roll the SLS (Space Launch System) rocket and Orion spacecraft for Artemis II off the launch pad and back to the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida. Cold temperatures and high winds are expected Tuesday, and rolling […]
