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 […]
NASA is targeting no earlier than Friday, March 6, for the launch of Artemis II, pending completion of required work at the launch pad, analysis of test data, and the outcome of a Flight Readiness Review in the coming days. The four astronauts set to fly around the Moon during the test flight entered quarantine […]
The Expedition 74 crew wrapped up the week with cardiac and respiratory studies and conducting space exercise research to keep astronauts healthy off the Earth. The International Space Station residents also packed a SpaceX Dragon cargo spacecraft before its return to Earth and maintained science and life support hardware.
NASA successfully fueled its SLS (Space Launch System) rocket and demonstrated the launch countdown for Artemis II on Thursday during a wet dress rehearsal at the agency’s Kennedy Space Center in Florida. Engineers loaded more than 700,000 gallons of liquid propellant into the rocket, sent a closeout crew to the launch pad to demonstrate closing the Orion spacecraft’s hatches, and completed two runs of terminal count — the final phase of the launch countdown. The Artemis II crew also observed part of […]
Relaxation, exercise, and biomedical studies were the key research objectives for the Expedition 74 crew on Thursday as NASA and its partners investigate ways to keep astronauts healthy on long-term missions. The International Space Station is also orbiting higher after the docked Progress 93 cargo craft fired its thrusters on Wednesday.
Live updates for the Artemis II wet dress rehearsal will be published on this page. Live views of the launch pad and test are available online. All times are Eastern. 10:18 p.m. The Artemis II wet dress rehearsal ended today at 10:16 p.m., concluding as planned at T-29 seconds in the countdown. NASA will hold […]
