United Launch Alliance to launch final Delta Heavy IV rocket today. Here’s how to watch live

The era of Delta Heavy IV is coming to an end.

For the last 64 years, United Launch Alliance’s (ULA’s) heavy-lift rocket has led an impressive career lofting large payloads into space. However, on Tuesday (March 28), the rocket will lift off one last time when it launches from Space Launch Complex-37 at Cape Canaveral Space Force Station in Florida. The launch window opens at 1:40 p.m. ET (1740 GMT).
