SpaceX Crew-4

SpaceX Crew-4 is a astronomy 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 Crew-4 rather than just read about it. In short: SpaceX Crew-4 was the Crew Dragon's fourth NASA Commercial Crew operational flight, and its seventh overall crewed orbital flight. The mission launched on April 27, 2022, at 07:52 UTC before docking with the International Space Station (ISS) at 23:37 UTC.

Key takeaways

SpaceX Crew-4 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SpaceX Crew-4 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SpaceX Crew-4 from memory before moving on to harder problems.

Reference excerpt

SpaceX Crew-4 was the Crew Dragon's fourth NASA Commercial Crew operational flight, and its seventh overall crewed orbital flight. The mission launched on April 27, 2022, at 07:52 UTC before docking with the International Space Station (ISS) at 23:37 UTC. It followed shortly after the private Axiom 1 mission to the ISS earlier in the month utilizing SpaceX hardware. Three American (NASA) astronauts and one European (ESA) astronaut were on board the mission. Crew-4 was the maiden flight of the Crew Dragon spacecraft named Freedom, named such by the crew because it "celebrates a fundamental human right, and the industry and innovation that emanate from the unencumbered human spirit". The booster used on this mission was the B1067, which makes it the first Commercial Crew mission to use a booster on its fourth flight (it previously was used to launch SpaceX Crew-3 in 2021).

Crew NASA astronauts Kjell Lindgren and Robert Hines were announced on February 12, 2021, to the crew. Samantha Cristoforetti was named the commander of Expedition 68 on May 28, 2021. Jessica Watkins was named mission specialist on November 16, 2021. Cristoforetti was later removed as commander of Expedition 68 due to the shortening of the Crew-4 mission.

Mission The mission duration was 170 days. The European part of the mission was called Minerva, named after the Roman goddess of wisdom, and it was European astronaut Cristoforetti's second mission to the ISS.

Worked examples

Example 1 — a first encounter with SpaceX Crew-4

Start with the simplest possible case. Write down what SpaceX Crew-4 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Crew-4 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 Crew-4 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 Crew-4

In research: SpaceX Crew-4 appears in astronomy 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 Crew-4 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 Crew-4 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2022 in Florida, April 2022 in the United States, Crew Dragon, so understanding it makes those chapters shorter.
In everyday life: Look for SpaceX Crew-4 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.

Frequently asked questions

What is SpaceX Crew-4 in simple terms?

Why does SpaceX Crew-4 matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study SpaceX Crew-4?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
