List of Constellation missions

List of Constellation missions 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 List of Constellation missions rather than just read about it. In short: The Constellation Program was NASA's planned future human spaceflight program between 2005 and 2009, which aimed to develop a new crewed spacecraft (Orion) and a pair of launchers (Ares I and Ares V) to continue servicing the International Space Station and return to the Moon. As of 2009, a single uncrewed suborbital launch test (Ares I-X) had been flown, with crewed missions anticipated to begin between 2014 (when…

Key takeaways

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

Reference excerpt

The Constellation Program was NASA's planned future human spaceflight program between 2005 and 2009, which aimed to develop a new crewed spacecraft (Orion) and a pair of launchers (Ares I and Ares V) to continue servicing the International Space Station and return to the Moon. As of 2009, a single uncrewed suborbital launch test (Ares I-X) had been flown, with crewed missions anticipated to begin between 2014 (when an uncrewed mission was indeed launched) and 2017-2019 (according to the independent Augustine Commission). On February 1, 2010, President Obama announced that he intended to cancel the program with the U.S. 2011 fiscal year budget. A revised proposal in April confirmed that the Orion spacecraft would be retained for future missions beyond low Earth orbit, with the Ares launchers redeveloped into the Space Launch System. However, the Constellation Program itself was cancelled, with low Earth orbit operations transferred to the Commercial Crew Development program, which itself would not begin crewed launches until Crew Dragon Demo-2 in 2020.

Development of mission plans In October 2006 NASA released a draft schedule of all planned NASA Constellation missions through 2019. This document included descriptions of a series of proposed vehicle test missions. In July 2007 the schedule was reviewed. In January 2008 the schedule was again reviewed. The most recent published set of milestones is from February 2009. Also, an independent assessment by the Review of United States Human Space Flight Plans Committee in October 2009 found that under NASA's then-current plans and budget the Ares I would not be ready to launch until 2017–2019, with the Ares V not available until the late 2020s. On October 11, 2010, the Constellation program was cancelled, ending development of the Altair, Ares I, and Ares V. The Orion Crew Exploration Vehicle was renamed the Orion Multi-Purpose Crew Vehicle (MPCV), to be launched on the Space Launch System.

Constellation missions After cancellation, one of the original launches took place anyway. Several more missions similar to Constellation missions would launch under the Orion test program and the following up Artemis program.

Abort tests These were planned to test the launch escape system of the Orion spacecraft on the launchpad.

Successor missions Several missions with modified profiles similar to the planned missions were launched after the conclusion of the Constellation program.

Worked examples

Example 1 — a first encounter with List of Constellation missions

Start with the simplest possible case. Write down what List of Constellation missions 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 List of Constellation missions 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 List of Constellation missions 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 List of Constellation missions

In research: List of Constellation missions 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 List of Constellation missions 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: List of Constellation missions is common in secondary-school and first-year university syllabi. It links to neighbouring topics Constellation program, Constellation program missions, Lists of space missions, so understanding it makes those chapters shorter.
In everyday life: Look for List of Constellation missions 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.
