In this episode of NASA Now, you’ll meet aerospace engineer Aisha Bowe, who is helping NASA solve this complex problem. Learn why there is no perfectly designed system and all technological solutions have trade-offs, such as safety, cost or efficiency. Learn about the types of conflicts aircraft encounter and how engineers use trade-offs to come up with the best overall solution.

On Earth, we can find life anywhere liquid water is present. Scientists now have realized that “anywhere” includes such extreme environments as ice-covered Antarctic lakes, the dry Chilean desert and cracks in deep subsurface rocks.
The organisms living in these harsh conditions are called extremophiles. They survive and often thrive in environments once thought too hot, too cold, too salty, too acidic, too dry, or with too high pressure or too much radiation for life to exist.
Scientists are studying microbes living in Earth’s extreme environments so they can better understand places where life might have existed on other bodies in our solar system.

NASA Now Minute: Extremophiles
NASA’s Voyager spacecraft are hurtling towards the edge of our solar system, more than 10 billion miles away from our sun. Interstellar space – the medium between stars – is a region no human-made craft has ever been. On Apr. 28, 2011, a live NASA TV program will feature mission scientists discussing the distant areas Voyager 1 and 2 are exploring, 10 billion miles away from our sun.

Garvin shows how the Lunar Reconnaissance Orbiter, or LRO, uses an instrument called LOLA to create better maps of the moon than we have ever had and highlights the connection between mapping and mathematics.

The Moderate Resolution Imaging Spectroradiometer, or MODIS, on NASA’s Aqua satellite and the MODIS sensor on NASA’s Terra satellite took photos of Japan’s earthquake and tsunami. Images were made with infrared and visible light to highlight the presence of water and other features on the ground.Link to the NES Virtual Campus home page.
Students and their families explored a variety of science stations. They looked through large telescopes set up by members of the Greater New Haven Astronomical Society; viewed lunar craters and the moons of Jupiter; and learned about constellations by viewing a planetarium show inside a portable planetarium.
