SMG is supporting the reentry and splashdown of Artemis II, targeted Friday April 10 approx 5:07pm PDT off the coast of San Diego. NASA astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen from the Canadian Space Agency will return to Earth following their lunar mission in the Orion spacecraft, named Integrity.


SMG provides weather forecast information to NASA flight controllers and managers for their decision making. Weather conditions are also provided for the Search and Rescue effort and to the NASA Scientifically Calibrated In-Flight Imagery (SCIFLI) team. SMG relies on additional observations from weather balloons released off the USS John P. Murtha and high resolution rapid refresh satellite imagery from NOAA’s GOES West.


Synopsis: On Friday morning April 10 an upper level low pressure is moving toward the west coast. The accompanying surface cold front is near the western California Bight. SMG is forecasting pre-frontal conditions and GO weather at the primary splashdown site: wind W at 10kts, wave height 4ft, visibility greater than 7 miles, SCT to BKN clouds at 1000ft and FEW at 25,000ft. Air temperature will be 63 degrees F and water temperature 66 degrees F.

Go Artemis II!
