Weather Still Favorable for Artemis I Wet Dress Rehearsal

Meteorologists with the U.S. Space Force Space Launch Delta 45 currently predict favorable weather conditions for tanking on April 3. Forecast for this afternoon slightly improved from yesterday. There is currently less than a 5% chance of lightning within five nautical miles of the launch pad. Weather constraints stipulate there must be less than a 20% chance lightning within 5 nautical miles of pad during the first hour of tanking. Meteorologists are also predicting a 10% chance of winds greater than 23 knots on April 3, when tanking begins. Winds must not be above 37.5 knots and the temperature cannot be below 41 degrees Fahrenheit.

The launch team is monitoring the potential for severe weather in the area later today and adjusting planned outdoor activities to remain on track for the wet dress rehearsal schedule.

While operations at the pad may not be visible during today’s activities at the launch pad, NASA is streaming live video of the rocket and spacecraft on the Kennedy Newsroom YouTube channel.

NASA is also sharing updates on the Exploration Ground Systems Twitter account. Real-time updates from Jeremy Parson, deputy manager of the Exploration Ground Systems Program, will begin on the account when the launch director and mission management team chair give a “go” for tanking operations, expected to occur around 7 a.m. EDT on Sunday, April 3.

The next blog update will be provided after the side flame deflectors are moved into place, which is expected to occur around 5:40 p.m. or L-21 hours.
