SpaceCub

SpaceCub 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 SpaceCub rather than just read about it. In short: SpaceCub was a design project for a homebuilt rocket. Between 1993 and 1994, Geoffrey A.

Key takeaways

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

Reference excerpt

SpaceCub was a design project for a homebuilt rocket. Between 1993 and 1994, Geoffrey A. Landis proposed that a vehicle designed to launch to the edge of space might be a feasible project for a "personal" spaceship, the equivalent of a Piper Cub for space. The insight was that a flight to "only" 100 km would reach the officially defined edge of space, and even though this is much easier a challenge than an orbital flight, such a suborbital flight would be of excitement to the public, and the pilot would be officially qualified as an astronaut. A small group of rocket enthusiasts, computer hobbyists, and science-fiction writers gathered together to do a preliminary design, with the ultimate goal of moving on to building a prototype, with (then) physics student David Burkhead leading the technical effort. The vehicle design was discussed in many venues, and presentations on the design progress were given in several conferences, such as the 1995 NSS International Space Development Conference, where it attracted considerable popular attention. The design was featured in print in places including the December 1994 Popular Mechanics, and the Brazilian popular magazine Istoé. Although a full-scale prototype of the SpaceCub was never built, the design (and the publicity surrounding the project) brought public attention to the concept that a small vehicle to fly a private pilot into space might be possible, and in that way served to stimulate the X Prize, which adopted the SpaceCub's goal of a 100-km flight altitude as a target for a competition. In its way, the SpaceCub vehicle is a predecessor to many of today's concepts for space tourism.

Worked examples

Example 1 — a first encounter with SpaceCub

Start with the simplest possible case. Write down what SpaceCub 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 SpaceCub 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 SpaceCub 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 SpaceCub

In research: SpaceCub 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 SpaceCub 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: SpaceCub is common in secondary-school and first-year university syllabi. It links to neighbouring topics Private spaceflight, Rocket-powered aircraft, Space access, so understanding it makes those chapters shorter.
In everyday life: Look for SpaceCub 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 SpaceCub in simple terms?

SpaceCub was a design project for a homebuilt rocket. Between 1993 and 1994, Geoffrey A.

Why does SpaceCub matter?

Because it connects several science 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 SpaceCub?

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.
