NASA commercial cargo provider SpaceX is targeting its 13th commercial resupply services mission to the International Space Station for no earlier than 2:53 p.m. EST Monday, Dec. 4. The Dragon spacecraft will spend about a month attached to the space station.
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 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.
The Falcon 9 rocket’s first-stage engines have finished their burn and separated from the vehicle. As the second stage continues the flight, the first stage will aim for a landing at Cape Canaveral Air Force Station.

T-minus three minutes and counting. The gantry-like strongback support structure has been lowered away from the rocket. Weather is “go.”
The terminal countdown begins at T-30 seconds.
The countdown continues toward liftoff at 12:31 p.m. EDT, 10 minutes from now. During this time, the Falcon 9’s engines will be chilled to condition them for launch, the strongback support structure will be moved away from the rocket, the flight computer will run its prelaunch checks and the rocket’s propellant tanks will be brought to flight pressure. Finally, SpaceX Launch Director Mike Taylor will verify “go for launch.”
The SpaceX CRS-12 mission aims to deliver more than 6,400 pounds of cargo to the International Space Station. In addition to supplies for the crew members living on the orbiting laboratory, the Dragon spacecraft is bringing computer resources, hardware and spacewalk equipment. No flight is complete without science, and the cargo includes materials to support the science and research projects Expeditions 52 and 53 will perform — approximately 250 investigations. Here are a few of the highlights:
Cosmic Ray Energetics and Mass (CREAM): From its vantage point on the station’s Japanese Experiment Module Exposed Facility, the CREAM instrument will spend three years measuring the charges of cosmic rays — information that could aid scientists in understanding the fundamental structure of the universe.
Crystallization of LRRK2 Under Microgravity Conditions (CASIS PCG 7): CASIS PCG 7 was developed by the Michael J Fox Foundation, Anatrace and Com-Pac International to take advantage of the microgravity environment in orbit to grow larger versions of LRRK2, a protein implicated in Parkinson’s disease.
Kestrel Eye (NanoRacks-KE IIM): This microsatellite carries an optical imaging system payload, including a commercially available telescope. Kestrel Eye is designed to help prove the concept that microsatellites can support critical operations and serve as viable payload platforms.
Effect of Microgravity on Stem Cell Mediated Recellularization (Lung Tissue): This experiment also leverages the microgravity environment — this time to test ways to grow new lung tissue. A specialized framework will allow scientists to observe the effect of gravity on different types of lung cells as they grow into new lung tissue.

Space Life and Physical Sciences Research and Applications: These experiments/payloads are developed to drive scientific and technological advances enabling both the expansion of human spaceflight and the enhancement of life on Earth.
