Due to not ideal weather conditions Saturday morning, SpaceX scrubbed their scheduled launch to focus on their next launch window Sunday morning.
SpaceX is expected to launch its 21st cargo supply mission for NASA from Kennedy Space Center.
After the Falcon 9 rocket sends the Cargo Dragon spacecraft on its way to the International Space Station, it will arrive about 24 hours later, bringing 6,400 pounds of research, supplies and special items for the astronauts aboard the ISS.
