But unlike previous CRS missions where SpaceX landed boosters back at Cape Canaveral, CRS-14 will not include a local recovery and instead focus on providing data as part of an expendable "demonstration mission". But with possible showers in the forecast, a contingency plan has the mission launching on Tuesday, when there is less chance of rain.
Dragon separated from Falcon 9's second stage about 10 minutes after liftoff and will attach to the space station on Wednesday, April 4.
SpaceX's Jessica Jensen, director of Dragon mission management, said the booster had previously launched in August 2017, and the Dragon flew to the space station in April 2016.
The cargo included materials that ISS astronauts would use to conduct experiments on how human beings and plants behave in space, the agency said. It's expected to hit the Pacific Ocean off the coast of California. The degree of this impact, and bone marrow's capacity to recoup when back on Earth, is important to space scientists and medicinal services suppliers alike. Expedition 55/56 crewmembers will therefore have about a month to unload and repack the Dragon before its scheduled departure.More news: Steven Bochco, creator of 'Hill Street Blues' and 'LA Law,' dies

Additionally, the Atmosphere-Space Interactions Monitor (ASIM) experiment will study severe thunderstorms in Earth's atmosphere as well as upper-atmospheric lightning.
Another piece of scientific equipment heading to the ISS will provide a new test bed for all kinds of research on subjects ranging from plants and fruit flies to protein crystals and cell cultures. The Passive Orbital Nutrient Delivery System (PONDS) arriving on Dragon uses a newly developed passive nutrient delivery system and the Veggie plant growth facility now aboard the space station to cultivate leafy greens.
NASA pays commercial partners like SpaceX to transport supplies to the station.
Both companies aspire to build satellite constellations - clusters of thousands of small satellites that will deliver internet connectivity to the whole planet - but they have a few years to go before either of them is ready to blast off. But there's more to SpaceX than meets the eye.
