From the NASA GRACE-FO prelaunch briefing: less than 10% chance of weather violation for tomorrow's launch from Vandenberg; cloudy skies but no visibility concerns. If delayed to Wednesday, 0% chance of weather violation.

Weather officer says Low Pressure area over Central/Southern California will thicken the marine layer. So expect foggy conditions at launch. #SpaceX #GRACEFO @IridiumComm #Falcon9

GRACE-FO Prelaunch Mission Status Briefing

NASA Video

Опубликовано: 21 мая 2018 г.

On May 21 a prelaunch briefing was held at Vandenberg Air Force Base in California for the GRACE Follow-On (GRACE-FO) mission, a joint mission with the German Research Centre for Geosciences (GFZ) that will provide critical measurements to help monitor the movement of water masses across the planet and mass changes within Earth itself. Monitoring changes in ice sheets and glaciers, underground water storage, and sea level provides a unique view of Earth's climate and has far-reaching benefits. The mission is planned to fly at least five years. The GRACE-FO spacecraft launches on May 22 at 3:47 p.m. EDT from Space Launch Complex-4E at Vandenberg with five Iridium NEXT communications satellites, as part of a commercial rideshare agreement. GFZ contracted GRACE-FO launch services from Iridium, and SpaceX is providing the Falcon 9 launch service.

Just arrived in California for Tuesday's launch of Iridium-6/GRACE-FO. Weather is looking very good for Tuesday, and everything else is on schedule.

An important note about tomorrow's #SpaceX launch. The 1st stage will NOT be recovered. It's a flight-proven Block 4 #Falcon9 (same core that launched Zuma in January) & will be expended. A fairing recovery attempt is expected, however.

SpaceX Falcon 9 B1043.2 with Iridium NEXT 6 with GRACE-FO have already departed the HIF (rollout) and spotted at the SLC-4E pad ahead of going vertical.
