  1. Cometary Dust Sample Return Mission • Launched: Feb. '99 • Comet Encounter: Jan. '04 • Sample Returned to Earth: Jan. '06

  2. Aerogel is 99.8% AIR, 0.02% silica Comet particle Collector inside the probe Each section was filled with aerogel able to collect comet samples travelling 7 times the speed of a bullet from a rifle. Aerogel is also a great insulator, it’s used in Mars rovers to insulate electronics, and also in skylights and innersoles.

  3. The Stardust sample return capsule is now on display at the National Air and Space Museum in Washington DC. The Stardust mission's top scientist, Donald Brownlee of the University of Washington, flashes victory signs for the successful arrival of Stardust material at NASA's Johnson Space Center.

  4. Many different groups have analyzed the same particles using many different instruments. INTERSTELLAR DUST GRAINS WERE FOUND AT THE TIP OF THE CARROT SHAPED TRACK IN THE AEROGEL

  5. Many scientists believe that comets may have brought the hydrogen that combined with the oxygen in Earth’s atmosphere to form water vapor during a period of heavy bombardment when the solar system was first formed. In addition, comets may also have brought complex, carbon-based molecules that could possibly have been the seeds for life on Earth. Comets are the delivery system of our solar system. In 2009 as scientist continue to study the Wild 2 samples from the Stardust mission, they have found glycine. This is the first time an amino acid has been found in a comet. This supports the theory that some of the ingredients needed to support life formed in space and were delivered to Earth by meteorite and comet impacts.

  6. Stardust-NExT 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. ESA’s ROSETTA mission A cloud-covered North America was captured at Nov. 13, 2009, when Rosetta by Rosetta's navigation camera during the final gravity assist before the 2014 comet landing.

  7. How do we use NASA technology? • Cordless rechargeable power tools • Smoke and carbon monoxide detectors • Laptop computers • Lightweight composites (baseball bats, race cars) • Water filtration systems • Improved insulating materials to protect fiirefighters, soldiers • Rechargeable batteries • “Jaws of Life” • Satellite imagery for weather prediction • Golf balls!

  8. A Career in STEM • Science • Technology • Engineering • Mathematics • Is it too • far reaching • to get there?

  9. Bridget Ziegelaar, is an Old Town native who graduated with a mechanical engineering degree from the University of Maine and a masters degree from George Washington University. • “As for my job, I am an Extravehicular Activity Flight Manager, which is just a fancy way of saying Spacewalk Manager. I am responsible for managing all aspects of the spacewalks on a given Shuttle flight, which involves making sure the crew has the right suits and tools and is properly trained to perform the required tasks on that specific mission.” “There is nothing more exciting for me than working on the next generation of wireless sensors for future space missions. My students quickly learn that they must rely heavily on their math and physics to design these battery-free wireless sensors.” • Dr. Ali Abedi is a Professor of Electrical and Computer Engineering at the University of Maine. One of his research projects is working to design a wireless monitoring system for an inflatable Lunar habitat.

  10. JOSEPH KNUBLE Graduate of: Brewer High School Worster Polytechnic Institute John Hopkins University Employed by: NASA Goddard Space Flight Center SMAP will provide space-based global mapping of soil moisture and freeze/thaw state with unprecedented accuracy, resolution, and coverage. Objectives include: Understand processes that link the terrestrial water, energy and carbon cycles Enhance weather and climate forecast skill Develop improved flood prediction and drought monitoring capabilities

  11. Maine’s Astronauts EDUCATION: College degree- Aerospace Engineering, U.S. Naval Academy PREVIOUS JOB: U.S. Navy Test Pilot Hobaugh flew as pilot on STS-104 (July 2001). He flew again as pilot on STS-118 (August 2007) with “Teacher in Space”, Barbara Morgan. He was the Commander of STS-129 (Nov. 2009). QUOTE: "There are some very surreal moments when you get into space, and you see someone floating around or something floating by for the first time and you're in space. But you've really just got to put your head down and work or you never get anything done." Charles Hobaugh BORN: Bar Harbor, Maine. EDUCATION: Mathematics, U.S. Naval Academy, 1993 Masters degree- Ocean Engineering, MIT, 2000 PREVIOUS JOB: Commander, Naval Special Warfare Task Unit, Afghanistan, Senior SEAL in Afghanistan Cassidy performed a spacewalk on his first mission on STS-127 (July 2009) LT. CMDR. CHRIS CASSIDY Grew up in York, Maine.
