An Orbital ATK Antares rocket will launch a commercial cargo spacecraft to the International Space Station Monday morning (May 21, 2018) at 4:39 a.m from NASA’s Wallops Flight Facility in Virginia.

Viewers from Massachusetts down to South Carolina, and roughly as far west as Pittsburgh, should be able to see the Antares spacecraft as it begins its ascent. If you’re outside the spectating zone, you can watch a livestream of the rocket launch on NASA TV.

The mission is expected to deliver some 7,400 pounds (3,400 kilograms) of supplies, scientific equipment and experiments to the ISS.
