The Internet Archive discovers and captures web pages through many different web crawls.
At any given time several distinct crawls are running, some for months, and some every day or longer.

This collection contains web crawls performed as the pre-inauguration crawl for part of the End of Term Web Archive, a collaborative project that aims to preserve the U.S. federal government web presence at each change of administration. Content includes publicly-accessible government websites hosted on .gov, .mil, and relevant non-.gov domains, as well as government social media materials. The web archiving was performed in the Fall and Winter of 2016 to capture websites prior to the January 20, 2017 inauguration. For more information, see http://eotarchive.cdlib.org/.
Stardust: A Mission With Many Scientific Surprises
The primary goal of the Stardust mission was to collect samples of a comet and return them to Earth for laboratory analysis. Comets are ancient bodies of frozen ice and dust that formed beyond the orbit of the most distant planet. They were expected to contain materials that the solar system formed from, preserved in ice for billions of years. When the international team of 200 scientists began examination of the returned particles, we found that the particles were indeed ancient building blocks of the solar system but the nature and origin of the particles was quite unexpected.
Stardust Spacecraft to Continue Flying
The Stardust-NExT will utilize the existing Stardust spacecraft to flyby Comet Tempel 1 in 2011, and observe changes in the
comet since Deep Impact visited it in 2005.
First Discovery of Life's Building Block in Comet
NASA scientists have discovered glycine, a fundamental building block of
life, in samples of comet Wild 2 returned by NASA's Stardust spacecraft.
Stardust Capsule To Go On Display At Smithsonian
Stardust sample return capsule will join the collection
of flight icons in the Smithsonian's National Air and Space Museum in
Washington. The capsule will go on public display in the museum's
Milestones of Flight Gallery on Oct. 1, the 50th anniversary of NASA.
Stardust Science Update
The 2007 round of sample processing and allocations of Cosmic Dust has been completed. The Cosmic Dust Lab (CDL)
at Johnson Space Center in Houston, Texas, will be closed down and cleaned in order to resume work associated with processing of the Interstellar Tray from Stardust.
Stardust's Big Surprise
The comet particles returned by the Stardust mission have been a real bonanza. They do contain some stardust grains from other stars but the majority of solids are solar system materials that appear to have formed over a very broad range of solar distances and perhaps over an extended time range.
NASA Study Finds New Kind of Organics in Stardust Mission
A team of scientists found a new class of organics in comet dust captured from comet Wild 2 in 2004 by NASA's Stardust spacecraft.
Stardust Findings Suggest Comets More Complex Than Thought
Comets may be more than just simple conglomerations of ice, dust and gases.
Scientists have found a wide range of compositions and structures for the comet Wild 2 particles that were captured and returned to Earth by NASA's Stardust spacecraft.
Aerogel: Catching Comet Dust
The primary objective of the Stardust mission is to capture both cometary samples and interstellar dust. Main challenges to accomplishing this successfully involve slowing down the particles from their high velocity with minimal heating or other effects that would cause their physical alteration.
