STS-67

STS-67 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-67 rather than just read about it.

Key takeaways

STS-67 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-67 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of STS-67 from memory before moving on to harder problems.

Mission highlights

Ultraviolet Imaging Experiments Astro-2 was the second dedicated Spacelab mission to conduct astronomical observations in the ultraviolet spectral regions (the first was the Astro-1 mission flown on STS-35). The Astro-2 Spacelab consisted of three unique instruments – the Hopkins Ultraviolet Telescope (HUT), the Ultraviolet Imaging Telescope (UIT) and the Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE). These took measurements from objects within the Solar System as well as individual stars, nebulae, supernova remnants, galaxies and active extragalactic objects. The data supplemented the data obtained from the Astro-1 mission. The purpose of the UIT was to observe UV radiation from space (most UV radiation is absorbed by Earth's atmosphere and cannot be studied from the ground). The data collected from UIT Astro-1 mission provided the first accurate knowledge of UV data from the universe. The UIT in the Astro-2 Spacelab was capable of capturing almost twice the UV spectrum of its predecessor. As STS-67 launched at a different time of year from STS-35, data was collected from portions of the sky that Astro-1 was not able to view.

Middeck Active Control Experiment (MACE) On the Middeck, science experiments included the Protein Crystal Growth Thermal Enclosure System Vapor Diffusion Apparatus-03 experiment (PCG-TES-03), the Protein Crystal Growth Single Thermal Enclosure System-02 (PCG-STES-02), the Shuttle Amateur Radio Experiment-II (SAREX-II), the Middeck Active Control Experiment (MACE), the Commercial Materials Dispersion Apparatus Instrumentation Technology Associates Experiments-03 (CMIX-03) and the Midcourse Space Experiment (MSX). The Middeck Active Control Experiment (MACE) was a space engineering research payload and activity. It consisted of a rate gyro, reaction wheels, a precision pointing payload, and a scanning and pointing payload that produces motion disturbances. The goal of the experiment was to test a closed loop control system that could compensate for motion disturbances. On orbit, Commander Stephen S. Oswald and Pilot William G. Gregory used MACE to test about 200 different motion disturbance situations over 45 hours of testing during the mission. Information from MACE was to be used to design better control systems that compensate for motion in future spacecraft.

Getaway Special Payloads Two Get Away Special (GAS) payloads were also on board. They were the G-387 and G-388 canisters. This experiment was sponsored by the Australian Space Office and AUSPACE ltd. The objectives were to make ultraviolet observations of deep space or nearby galaxies. These observations were made to study the structure of galactic supernova remnants, the distribution of hot gas in the Magellanic Clouds, the hot galactic halo emission, and emission associated with galactic cooling flows and jets. The two GAS canisters were interconnected with a cable. Canister 1 had a motorized door assembly that exposed a UV telescope to space when opened. UV reflective filters on the telescopes optics determine its UV bandpass. Canister 2 contained two video recorders for data storage and batteries to provide experiment power. It was Space Shuttle Endeavour's longest flight and the longest flight overall that was not flown by Columbia.

Mission insignia The spiral galaxy, Jupiter, and the four moons (total of six space objects) as well as the seven stars of the insignia symbolize the flight's numerical designation in the Space Transportation System's mission sequence. Endeavour, with ASTRO-2, is speeding by.

Worked examples

Example 1 — a first encounter with STS-67

Start with the simplest possible case. Write down what STS-67 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-67 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-67 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-67

In research: STS-67 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-67 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-67 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Crewed space observatories, Edwards Air Force Base, Space Shuttle missions, so understanding it makes those chapters shorter.
In everyday life: Look for STS-67 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.

Crew Crew seat assignments Mission highlights Ultraviolet Imaging Experiments Astro-2 was the second dedicated Spacelab mission to conduct astronomical observation…

Why does STS-67 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-67?

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.
