STS-100

STS-100 is a physics 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 STS-100 rather than just read about it. In short: STS-100 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Endeavour. STS-100 launched on 19 April 2001, and installed the ISS Canadarm2 robotic arm.

Key takeaways

STS-100 belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect STS-100 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of STS-100 from memory before moving on to harder problems.

Mission highlights The highest priority objectives of the flight were the installation, activation and checkout of the Canadarm2 robotic arm on the station. The arm - manufactured by MDA Space Missions under contract of the Canadian Space Agency and NASA, went into operation on 28 April 2001. It was critical to the capability to continue assembly of the International Space Station. The arm was also necessary to attach a new airlock to the station on the subsequent shuttle flight, mission STS-104. The final component of the Canadarm is the Mobile Base System (MBS), which was installed on board the station during the STS-111 flight. Other major objectives for Endeavour's mission were to berth the Raffaello logistics module to the station, activate it, transfer cargo between Raffaello and the station, and reberth Raffaello in the shuttle's payload bay. Raffaello is the second of three Italian Space Agency-developed Multi-Purpose Logistics Module, manufactured out of stainless steel at the Cannes Mandelieu Space Center; that were launched to the station. The Leonardo module was launched and returned on the previous shuttle flight, STS-102, in March. Remaining objectives included the transfer of other equipment to the station such as an Ultra-High Frequency communications antenna and a spare electronics component to be attached to the exterior during space walks. Finally, the transfer of supplies and water for use aboard the station, the transfer of experiments and experiment racks to the complex, and the transfer of items for return to Earth from the station to the shuttle were among the objectives. Endeavour also boosted the station's altitude and performed a flyaround survey of the complex, including recording views of the station with an IMAX cargo bay camera. All objectives were completed without incident, and reentry and landing happened uneventfully on 1 May 2001. During this mission, astronaut Chris Hadfield made the first spacewalk by a Canadian.

Spacewalks

Wake-up calls NASA began a tradition of playing music to astronauts during the Gemini program, which was first used to wake up a flight crew during Apollo 15. Each track is specially chosen, often by their families, and usually has a special meaning to an individual member of the crew, or is applicable to their daily activities.

Worked examples

Example 1 — a first encounter with STS-100

Start with the simplest possible case. Write down what STS-100 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 STS-100 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 STS-100 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 STS-100

In research: STS-100 appears in physics 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 STS-100 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: STS-100 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2021 in Florida, April 2001 in the United States, Edwards Air Force Base, so understanding it makes those chapters shorter.
In everyday life: Look for STS-100 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 STS-100 in simple terms?

STS-100 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Endeavour. STS-100 launched on 19 April 2001, and installed the ISS Canadarm2 robotic arm.

Why does STS-100 matter?

Because it connects several physics 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 STS-100?

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.
