Petey (satellite)

Petey (satellite) 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 Petey (satellite) rather than just read about it. In short: Petey (or 3CS-3) was a satellite, part of Three Corner Satellite (3CS) project, a three satellite (Sparkie, Ralphie and Petey) student research project. It was designed and built by mostly undergraduate students at the New Mexico State University as part of the Air Force Research Laboratory's University Nanosat Program.

Key takeaways

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

Reference excerpt

Petey (or 3CS-3) was a satellite, part of Three Corner Satellite (3CS) project, a three satellite (Sparkie, Ralphie and Petey) student research project. It was designed and built by mostly undergraduate students at the New Mexico State University as part of the Air Force Research Laboratory's University Nanosat Program. It was responsible for communication system in 3CS project. Satellite was not completed in time for launch of 3CS on December 21, 2004, and later was donated to the National Air and Space Museum’s Steven F. Udvar-Hazy Center. The two other 3CS satellites Sparkie and Ralphie were launched 21 December 2004 on the first launch of Delta IV Heavy. The launch was a partial failure, and in particular the two 3CS satellites did not achieve orbit. Satellite carries the name of New Mexico State University's mascot, Pistol Pete.

Worked examples

Example 1 — a first encounter with Petey (satellite)

Start with the simplest possible case. Write down what Petey (satellite) 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 Petey (satellite) 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 Petey (satellite) 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 Petey (satellite)

In research: Petey (satellite) 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 Petey (satellite) 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: Petey (satellite) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2004 in spaceflight, so understanding it makes those chapters shorter.
In everyday life: Look for Petey (satellite) 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.
