SpaceX CRS-34 Mission Overview

A SpaceX Falcon 9 rocket will launch the CRS-34 Dragon spacecraft to deliver cargo to and from the International Space Station for NASA.

The 14th flight under NASA's Commercial Resupply Services-2 contract with SpaceX, the CRS-34 Dragon will carry research, logistics and hardware for the Expedition 74 crew including:

• ODYSSEY (Outcomes of microbial Dynamics during Spaceflight and in SimulatEd microgravity) — to determine whether Earth-based simulators can be considered as proxies for spaceflight research and get a better understanding of the mechanisms behind biofilm formation and exchange of genetic material when exposed to space-like conditions.

• Green Bone — to test a new bone scaffold made from rattan wood that acts like real bone.

• SPARK (Spleen Activity in Space Anemia and Red Cells Kinetics) — to study how the spleen changes and how red blood cells break down in space.

• STP-H11-STORIE — to understand the origin and composition of Earth's ring current, energetic particle populations in near-Earth space, by imaging energetic neutral atoms (ENAs) decay emissions.

• Laplace — to study the evolution and growth of dust aggregates in proto-planetary disks and evaluate the fundamental aspects of gas and particle transport phenomena in dust clouds.

Teams stood down from today's launch opportunity due to inclement weather. We're now targeting no earlier than 6:05 p.m. EDT Friday, May 15, for the launch.

NASA Science, Cargo Launch on 34th SpaceX Resupply Mission to Station

The 34th SpaceX commercial resupply mission under contract with NASA is headed to the International Space Station with new scientific experiments after lifting off at 6:05 p.m. EDT Friday (May 15) on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

The SpaceX spacecraft, loaded with nearly 6,500 pounds of cargo for the space station's Expedition 74 crew, is scheduled to autonomously dock at about 7 a.m. Sunday, May 17, to the forward port of the station's Harmony module.

In addition to cargo for the crew aboard the space station, Dragon will deliver several new experiments, including a project to determine how well Earth-based simulators mimic microgravity conditions, a bone scaffold made from wood that could produce new treatments for fragile bone conditions like osteoporosis, and equipment to help researchers evaluate how red blood cells and the spleen change in space. The Dragon spacecraft also will carry a new instrument to study charged particles around Earth that can impact power grids and satellites, an investigation that could provide a fundamental understanding of how planets form, and an instrument designed to take highly accurate measurements of sunlight reflected by Earth and the Moon.

These experiments are just a sample of the hundreds of investigations conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that aren't possible on Earth. The space station helps NASA understand and overcome the challenges of human spaceflight, expand commercial opportunities in low Earth orbit, and build on the foundation for long-duration missions to the Moon, as part of the Artemis program, and to Mars.

The Dragon spacecraft is scheduled to remain at the station until mid-June, when it will depart and return to Earth with time-sensitive research and cargo, ahead of splashing down off the coast of California.

SpaceX Dragon Docks to Station Filled with New Science Experiments

On Sunday (May 17) at 6:37 a.m. EDT (1037 GMT), the SpaceX Dragon spacecraft docked to the forward port of the International Space Station's Harmony module, carrying nearly 6,500 pounds of food, supplies, and equipment for the Expedition 74 crew.

This is the 34th SpaceX commercial resupply services mission to the space station for NASA.
