ICESat Ice, Cloud and Land Elevation satellite was launched 1/12/03 into a 590 km sun-synch orbit What’s the inclination? Two single-axis articulated solar array wings Science instrument includes a laser system to measure distance a Global Positioning System (GPS) receiver a star-tracker attitude determination system The laser will transmit 4 ns pulses of infrared light (1064 nanometers wavelength) and visible green light (532 nanometers) Photons reflected from surface of Earth and atmosphere will be collected in a 1 meter diameter telescope Laser pulses at 40 Hz will illuminate footprints 70 meters in diameter, spaced at 170-meter intervals along Earth's surface Ice, Cloud and Land Elevation

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
