L-1 Day Briefings Scheduled for SpaceX CRS-13

Today marks “L-1” – launch minus one day – for tomorrow’s scheduled launch of SpaceX’s 13th commercial resupply to the International Space Station. Liftoff of the SpaceX Falcon 9 rocket and Dragon spacecraft is planned for 11:46 a.m. EST Tuesday from Space Launch Complex 40 at Cape Canaveral Air Force Station. Meteorologists with the U.S. Air Force 45th Space Wing are predicting a 90 percent chance of favorable weather at launch time, with liftoff winds the primary concern.

Mission coverage begins today with two news briefings. Both will be broadcast on NASA Television.

Live coverage from the countdown begins Tuesday morning at 11:15 a.m. here on NASA’s Launch Blog and on NASA Television.

Liftoff Sets Dragon on Course for Wednesday Rendezvous

Crew members aboard the International Space Station can expect a special delivery Wednesday morning. A SpaceX Dragon spacecraft loaded with more than 6,400 pounds of supplies, equipment and science materials is heading their way after the successful liftoff of SpaceX CRS-12 at 12:31 p.m. EDT from NASA Kennedy Space Center’s Launch Complex 39A.

The on-time liftoff marked a spectacular conclusion to a countdown that proceeded like clockwork throughout the morning, aided by cooperative weather conditions across the launch site. With a sonic boom sounding across Florida’s Space Coast, the first stage returned to SpaceX’s Landing Zone 1 on Cape Canaveral Air Force Station while the rocket’s second stage finished the task of propelling Dragon to orbit.

After a successful separation from the Falcon 9, the Dragon spacecraft deployed its solar arrays and embarked on its two-day pursuit of the orbiting laboratory. Watch the rendezvous and grapple live on NASA TV starting at 5:30 a.m. Wednesday.

Here’s one more look back at today’s launch:

Dragon’s Solar Arrays Deploying

Dragon’s solar arrays are unfurling and the spacecraft is on course to deliver more than 6,400 pounds of cargo to the International Space Station two days from now. Live coverage of the rendezvous and capture will begin at 5:30 a.m. Wednesday, Aug. 16, on NASA TV, with installation coverage set to begin at 8:30 a.m.
