SpaceX Crew-3

SpaceX Crew-3 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-3 rather than just read about it. In short: SpaceX Crew-3 was the Crew Dragon's third NASA Commercial Crew operational flight, and its fifth overall crewed orbital flight. The mission successfully launched on November 11, 2021, at 02:03:31 UTC to the International Space Station.

Key takeaways

SpaceX Crew-3 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-3 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SpaceX Crew-3 from memory before moving on to harder problems.

Reference excerpt

SpaceX Crew-3 was the Crew Dragon's third NASA Commercial Crew operational flight, and its fifth overall crewed orbital flight. The mission successfully launched on November 11, 2021, at 02:03:31 UTC to the International Space Station. It was the maiden flight of Crew Dragon Endurance. This launch brought the total number of humans who have been to space to more than 600 with Maurer (600) and Barron (601).

Name Crew Dragon capsules have been given names by their initial crews — Endeavour for the first, and Resilience for the second. On October 7, 2021, it was announced that the third capsule will be called Endurance. The name honors the SpaceX and NASA teams that endured through a pandemic, building the spacecraft and training the astronauts who flew it. The name also honors Endurance, the ship used by Shackleton's Imperial Trans-Antarctic Expedition. The three-masted vessel sank in 1915 after being bound in ice before reaching Antarctica.

Crew German ESA astronaut Matthias Maurer was selected first for the mission in September 2020. NASA astronauts Raja Chari and Thomas Marshburn were added on December 14, 2020, to the crew. The fourth seat was left open in anticipation that a Russian cosmonaut would take the seat, marking the beginning of a barter agreement that would see NASA and Roscosmos trade seats on the Soyuz and Commercial Crew Vehicles, although in April 2021 then-acting NASA administration Steve Jurczyk said that this agreement would be unlikely to start until after Crew-3 had launched. The fourth seat was assigned to Kayla Barron in May 2021. Chari is the first rookie astronaut to command a NASA space mission since the Skylab 4 crew blasted off to the Skylab space station in 1973. Gerald Carr, who had not flown in space before, led a three-man crew on an 84-day flight on the Skylab. This was also the first spaceflight for Barron and Maurer.

The first astronauts of this NASA Astronaut Group 22 (nicknamed The Turtles) to fly to space, Raja Chari and Kayla Barron on SpaceX Crew-3 took a stuffed turtle as zero-g indicator to pay a tribute to their astronaut group. Additionally, to include the other crew members on board, Matthias Maurer and Tom Marshburn the turtle was named "Pfau", a German word meaning "Peacock" for Matthias Maurer, who is German, and for Tom Marshburn, who was part of NASA Astronaut Group 19 (nicknamed The Peacocks).

Mission The third SpaceX operational mission in the Commercial Crew Program was originally scheduled to launch on October 31, 2021. However, it was delayed to November 3, 2021, due to unfavorable weather in the Atlantic Ocean, and then further delayed to November 7, 2021, due to a minor medical issue with one of the astronauts. Due to expected bad weather, it was again delayed to November 9, 2021. Due to the launch delays, NASA decided to return the astronauts from Crew-2 before Crew-3 launched, thus being the first Crew Dragon indirect handover of space station crews. SpaceX Crew-2 departed the station on November 8, 2021, and splashed down on November 9, 2021. SpaceX Crew-3 mission launched from Cape Canaveral on November 11, 2021, at 02:03:31 UTC. The return of Crew-3 was delayed multiple times, from April 2022 to early May. Undocking happened on May 5 (05:20 UTC), with splashdown occurring the following day after spending 176 days in space. The European segment of the mission is called "Cosmic Kiss".

Worked examples

Example 1 — a first encounter with SpaceX Crew-3

Start with the simplest possible case. Write down what SpaceX Crew-3 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-3 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-3 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-3

In research: SpaceX Crew-3 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-3 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-3 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2021 in Florida, Crew Dragon, Fully civilian crewed orbital spaceflights, so understanding it makes those chapters shorter.
In everyday life: Look for SpaceX Crew-3 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.
