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 […]
Expedition 74 was off duty on Monday following a weekend of crew handover activities, cargo packing, and microbiology research. A SpaceX Dragon spacecraft will also depart the International Space Station for return to Earth later this week.
Weather pending, NASA will roll the SLS (Space Launch System) rocket and Orion spacecraft for Artemis II off the launch pad at the agency’s Kennedy Space Center in Florida as soon as Tuesday, Feb. 24. Engineers are continuing to prepare for the move after encountering an issue with the flow of helium to the rocket’s […]
Editor’s note: NASA has updated an earlier version of this blog to provide additional details. NASA is taking steps to potentially roll back the Artemis II rocket and Orion spacecraft to the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida after overnight Feb. 21 observing interrupted flow of helium to the […]
