From NASA:

For the first time in 99 years, a total solar eclipse will cross the entire nation Aug. 21. Representatives from NASA, other federal agencies, and science organizations, will provide important viewing safety, travel and science information during two briefings at the Newseum in Washington starting at 1 p.m. EDT Wednesday, June 21.

The event will air live on NASA Television and stream on the agency’s website.

Over the course of 100 minutes, 14 states across the United States will experience more than two minutes of darkness in the middle of the day. Additionally, a partial eclipse will be viewable across all of North America. The eclipse will provide a unique opportunity to study the sun, Earth, moon and their interaction because of the eclipse’s long path over land coast to coast. Scientists will be able to take ground-based and airborne observations over a period of an hour and a half to complement the wealth of data and images provided by space assets.

The June 21 briefings are:

Logistics Briefing: 1 to 2 p.m.

Science Briefing: 2:30 to 3:30 p.m.
