SpaceX CRS-34

SpaceX CRS-34 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand SpaceX CRS-34 rather than just read about it. In short: SpaceX CRS-34, also known as SpX-34, was an International Space Station (ISS) cargo resupply mission contracted by NASA and operated by SpaceX. The flight launched on May 15, 2026, from Space Launch Complex 40 at Cape Canaveral Space Force Station.

Key takeaways

SpaceX CRS-34 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SpaceX CRS-34 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SpaceX CRS-34 from memory before moving on to harder problems.

Reference excerpt

SpaceX CRS-34, also known as SpX-34, was an International Space Station (ISS) cargo resupply mission contracted by NASA and operated by SpaceX. The flight launched on May 15, 2026, from Space Launch Complex 40 at Cape Canaveral Space Force Station. It is SpaceX's 34th cargo delivery mission under the Commercial Resupply Services program. The mission used Cargo Dragon C209, marking the spacecraft's sixth flight, along with Falcon 9 booster B1096 on its sixth flight.

Manifest The spacecraft was loaded with 2,948 kg (6,499 lb) of cargo, comprising:

Pressurized payload: 2,132 kg (4,700 lb) Crew supplies: 618 kg (1,362 lb) Science investigations: 831 kg (1,832 lb) Spacewalk equipment: 128 kg (282 lb) Vehicle hardware: 469 kg (1,034 lb) Computer resources: 84 kg (185 lb) Unpressurized payload: 816 kg (1,799 lb) CLARREO Pathfinder and STP-H11 were carried as unpressurized payloads inside the trunk Some NASA scientific payloads on CRS-34 are:

ODYSSEY: microgravity simulators to conduct space biology studies. Green Bone: a bone scaffold made from rattan wood that acts like real bone. SPARK: studies how the spleen changes and how red blood cells break down in space. CLARREO Pathfinder: measures sunlight reflected by the Earth and the Moon. Laplace: study of the evolution and growth of dust aggregates in proto-planetary disks. STORIE: charged particle "storm ring" detector. Other cargo includes replacement parts and upgrades for onboard exercise equipment, water management, waste management, as well as new maintenance equipment. The mission also carried a prototype of the French IVA spacesuit developed by Spartan Space for testing by the ESA astronaut Sophie Adenot.

Launch

NASA selected a targeted launch date of no earlier than May 12, 2026, at 00:16 UTC (7:16 p.m. EDT on May 11) for CRS-34, with a backup opportunity on May 13 at 22:50 UTC (6:50 p.m. EDT). On May 11, 2026, at 17:00 UTC (1:00 p.m. EDT), the 45th Weather Squadron forecast a 35 percent chance of favorable weather conditions for the May 12 attempt, improving to 65 percent for the May 13 opportunity. NASA scrubbed the May 12, 2026, attempt at 20:26 UTC (4:26 p.m. EDT) due to poor weather conditions. The following day's attempt was scrubbed at T−28 seconds at approximately 22:50 UTC (6:50 p.m. EDT). A third launch attempt was successfully on May 15, 2026, at 22:05:41 UTC (18:05:41 EDT). The 45th Weather Squadron forecasted a 90 percent chance of favorable conditions for the launch.

Launch attempt summary Note: Times are local to the launch site (Eastern Daylight Time).

Arrival NASA astronaut Jack Hathaway and ESA astronaut Sophie Adenot monitored CRS-34's automatic arrival and docking with the ISS at 10:37 UTC on May 17.

Return and disposal CRS-34 undocked from the ISS on June 16 at 12:25pm, completing its 30 day stay at the ISS before splashing down outside of Oceanside at 8:11am on June 17. CRS-34 brought back several research projects including bioprinted organ and cartilage tissue, data on improving cryogenic fuel storage, and new DNA-inspired materials for cancer treatments.

Worked examples

Example 1 — a first encounter with SpaceX CRS-34

Start with the simplest possible case. Write down what SpaceX CRS-34 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to SpaceX CRS-34 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about SpaceX CRS-34 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of SpaceX CRS-34

In research: SpaceX CRS-34 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses SpaceX CRS-34 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: SpaceX CRS-34 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2026 in Florida, Cargo Dragon, May 2026 in the United States, so understanding it makes those chapters shorter.
In everyday life: Look for SpaceX CRS-34 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
