A SpaceX Falcon 9 rocket lifted off on the CRS-14 commercial resupply mission to the International Space Station at 4:30 p.m. on 2 April 2018 from Space Launch Complex 40 at Cape Canaveral Air Force Station.

Excerpts about the mission from the SpaceX press release:

SpaceX is targeting Monday, April 2, 2018 for an instantaneous launch of its fourteenth Commercial Resupply Services mission (CRS-14) at 4:30 p.m. EDT, or 20:30 UTC, from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida.

[The] Dragon [spacecraft] will separate from Falcon 9's second stage about 10 minutes after liftoff and attach to the space station on Wednesday, April 4, 2018.

Both Falcon 9 and the Dragon spacecraft for the CRS-14 mission are flight proven. Falcon 9's first stage previously supported the CRS-12 mission in August 2017 and Dragon previously supported the CRS-8 mission in April 2016.

SpaceX will not attempt to recover Falcon 9's first stage after launch.

Dragon Spacecraft
Dragon will be filled with about 5,800 pounds of supplies, payloads and vehicle hardware, including critical materials to directly support science and research investigations that will occur onboard the orbiting laboratory.

On Wednesday, April 4 International Space Station crew members will use the station's 57.7-foot (17.6- meter) robotic arm to reach out and capture the Dragon spacecraft and attach it to the orbiting laboratory.

Dragon will return to Earth with more than 3,900 pounds of cargo after an approximately one-month stay at the International Space Station. About five hours after Dragon leaves the space station, it will conduct its deorbit burn, which lasts up to 10 minutes. It takes about 30 minutes for Dragon to reenter the Earth's atmosphere and splash down in the Pacific Ocean off the coast of Baja California.
