Aeolian Landscape is an exhibit in which a miniature wind-swept desert landscape is recreated by an electric fan and finely ground sand that mimics the process of wind picking up and depositing small particles. Visitors can change the direction of the fan, influencing the shape of the dunes. Want to get off the grid but think it’s just too expensive? UCB's Dr. Jeff Grossman explains how nanotechnology may be used to make solar panels cheaper. We’ll also hear from philosopher Patrick Lin of the Nanoethics Group about ethical dilemmas that crop up when we try to improve our lives through nanotechnology. The two Mars Rovers are alive and well after surviving their second Martian winter. Come and see photos of discoveries they made during their third year on Mars, with Exploratorium Senior Scientist Paul Doherty.
Join Exploratorium staff Paul Doherty and Robyn Higdon as they discuss the Transit of Mercury. On November 8, 2006, Mercury slowly slid across the face of the sun during a relatively rare event known as a transit. The Exploratorium's Live@ crew was at the Kitt Peak National Observatory in Arizona to cover the event. This webcast includes a brief history of Kitt Peak and its 21 telescopes. On March 29, 2006, a total solar eclipse occurred as the moon moved directly between the earth and the sun. The moon's shadow fell on the earth, first darkening the eastern tip of Brazil, and then moved across the Atlantic Ocean to make landfall in Ghana, Africa. It continued moving northeast through Nigeria, Niger, Libya, Egypt, across the Mediterranean and into Turkey, where an Exploratorium team was waiting. An clip of the Aeolian Landscape exhibit by artist Ned Kahn. Blowing air sculpts sand into an ever-changing landscape. On December 11, 2005, Opportunity, one of the twin rovers exploring Mars, celebrated its first Martian birthday. Opportunity had been on the red planet 687 Earth days, which is one Martian year. (A year is the time it takes a planet to make a complete loop around the sun). Join us for a look back over the those 687 days of discovery: what we learned, what we saw, and what questions remained unanswered. On the occasion of Hubble's 15th birthday we unveil two spectacular mosaic images from the telescope, discuss the amazing accomplishments of Hubble during the past 15 years, and look at some of the images from space. NASA's Mars Exploration Rovers, Spirit and Opportunity, have long outlived their life expectancy of three months. Join us as we sum up the rover data and explain how this information changes our view of Mars.
