Stellar Wind

Stellar Wind 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 Stellar Wind rather than just read about it. In short: "Stellar Wind" (or "Stellarwind") was the code name of a warrantless surveillance program begun under the George W. Bush administration's President's Surveillance Program (PSP).

Key takeaways

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

Reference excerpt

"Stellar Wind" (or "Stellarwind") was the code name of a warrantless surveillance program begun under the George W. Bush administration's President's Surveillance Program (PSP). The National Security Agency (NSA) program was approved by President Bush shortly after the September 11, 2001 attacks and was revealed by Thomas Tamm to The New York Times in 2004. Stellar Wind was a prelude to new legal structures that allowed President Bush and President Barack Obama to reproduce each of those programs and expand their reach.

Program scope The program's activities involved data mining of a large database of the communications of American citizens, including e-mail communications, telephone conversations, financial transactions, and Internet activity. William Binney, a retired technical leader with the NSA, discussed some of the architectural and operational elements of the program at the 2012 Chaos Communication Congress. The intelligence community also was able to obtain from the U.S. Treasury Department suspicious activity reports, or "SARS", which are reports of activities such as large cash transactions that are submitted by financial institutions under anti-money laundering rules. There were internal disputes within the U.S. Justice Department about the legality of the program, because data is collected for large numbers of people, not just the subjects of Foreign Intelligence Surveillance Act (FISA) warrants. During the Bush administration, the Stellar Wind cases were referred to by FBI agents as "pizza cases" because many seemingly suspicious cases turned out to be food takeout orders. According to then-FBI Director Robert Mueller, approximately 99% of the cases led nowhere, but "it's that other 1% that we've got to be concerned about".

2004 conflict From a report by the inspectors general of six US intelligence agencies that was declassified in September 2015, it became clear that President Bush had originally authorized the collection of telephone and e-mail metadata only if one end of the communications was foreign or when there was a link to terrorism. But in 2004, the Justice Department discovered that the NSA was apparently also collecting the metadata of purely domestic communications, after which President Bush declared that NSA had always been allowed to do so, but that analysts were only allowed to look at metadata related to terrorism. With this revised formulation, Bush reauthorized the program on March 11, 2004. In 2004, the head of the Office of Legal Counsel (OLC), Jack Landman Goldsmith, wrote at least two legal memos authorizing the program, "We conclude only that when the nation has been thrust into an armed conflict by a foreign attack on the United States and the president determines in his role as commander in chief ... that it is essential for defense against a further foreign attack to use the wiretapping capabilities of the National Security Agency within the United States, he has inherent constitutional authority" to order warrantless wiretapping—"an authority that Congress cannot curtail", Goldsmith wrote in a 108-page memo dated May 6, 2004. In March 2004, the OLC concluded the e-mail program was not legal.

Revelations In March 2012, Wired magazine published "The NSA Is Building the Country's Biggest Spy Center (Watch What You Say)" talking about a vast new NSA facility in Utah and said, "For the first time, a former NSA official has gone on the record to describe the program, codenamed Stellarwind, in detail", naming the official William Binney, a former NSA code breaker. Binney went on to say that the NSA had highly secured rooms that tap into major switches, and satellite communications at both AT&T and Verizon. The article suggested that the supposedly-terminated Stellar Wind continues as an active program. This conclusion was supported by the exposure of Room 641A in AT&T's operations center in San Francisco in 2006. In June 2013, The Washington Post and The Guardian published an Office of the Inspector General (OIG) draft report, dated March 2009, leaked by Edward Snowden detailing the Stellar Wind program. No doubt remained about the continuing nature of the surveillance program. In September 2014, The New York Times asserted, "Questions persist after the release of a newly declassified version of a legal memo approving the National Security Agency's Stellarwind program, a set of warrantless surveillance and data collection activities secretly authorized after the terrorist attacks of Sept. 11, 2001," as an introductory headline summary with a link. The accompanying article addressed the release of a newly declassified version of the May 2004 memo. Note was made that the bulk of the program—the telephone, Internet, and e-mail surveillance of American citizens—remained secret until the revelations by Edward Snowden that, to date, significant portions of the memo remain redacted in the newly released version, and that doubts and questions about its legality persist.

Worked examples

Example 1 — a first encounter with Stellar Wind

Start with the simplest possible case. Write down what Stellar Wind 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 Stellar Wind 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 Stellar Wind 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 Stellar Wind

In research
Stellar Wind 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 Stellar Wind 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
Stellar Wind is common in secondary-school and first-year university syllabi. It links to neighbouring topics Applied data mining, National Security Agency, so understanding it makes those chapters shorter.
In everyday life
Look for Stellar Wind 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.

What is Stellar Wind in simple terms?

"Stellar Wind" (or "Stellarwind") was the code name of a warrantless surveillance program begun under the George W. Bush administration's President's Surveillance Program (PSP).

Why does Stellar Wind 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 Stellar Wind?

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.
