Your Reply: HTML is ON UBB Code is ON Smilies Legend	[QUOTE]Originally posted by Robert Pearlman: [B]From an Alliant Techsystems (ATK) release: <BLOCKQUOTE>Alliant Techsystems announces that the Ultraflex Solar Arrays deployed and now provide power to the Mars Phoenix Lander. This is the first flight for this unique solar array technology developed by ATK's Goleta, California facility. Each Ultraflex array unfolded like an oriental fan into a circular shape 2.1 meters in diameter and will generate 770 watts of power from sunlight at the distance Earth is from the sun. Since Mars is approximately 1.5 times farther from the sun, the solar arrays will produce less than half the power possible on Earth.</BLOCKQUOTE> The same [URL=http://nmp.nasa.gov/st8/tech/solar_array3.html]Ultraflex technology[/URL] will be used for the Orion Crew Exploration Vehicle's 5-meter solar arrays.[/B][/QUOTE]
