Early Tuesday morning SpaceX launch to the ISS

Well before sunrise on Tuesday, 6:33 AM EDT with sunrise at 7:22 AM, SpaceX is set to launch a cargo payload of about 6300 pounds to the ISS. The mission is known as CRS-35 and, yes, the "35" means it's the 35th of these Commercial Resupply Service missions.

This mission will deliver the fourth pair of iROSA solar arrays which will be used to provide additional power to the station. 

The mission can be watched via NASASpaceflight (.com)  or via Space.com's link on NASA video on YouTube as well. The NASA Spaceflight video will start around one hour before liftoff, while the Space.com video starts quite a bit later 6:15 a.m. EDT (1015 GMT) or 45 minutes after NASASpaceflight.com's video starts.
