"Observing the Earth From Space With Landsat"
The first Landsat satellite blasted into orbit around the Earth in 1972, carrying an extremely sensitive instrument. Its federal mandate was to consistently document lands and coastal regions around the globe at 30-meter resolution, recording reflected light in carefully selected red, green, and infrared wavelengths. it provided an objective, space-based perspective that boosted commercial and scientific innovation, and lifted our nation to a leadership position in Earth observations from space that continues.
Our speaker, Jeannie Allen of Sigma Space Corporation, will highlight major features of Landsat, what the satellites see, and stories of its discoveries and contributions to our national and global society. She will show how anyone can download their own Landsat scenes and analyze them using no-cost software.
TELESCOPES! MAKE THEM-USE THEM-FIX THEM!
Next session - Wednesday, March 19th
TAAS has a wonderful special interest group-Amateur Telescope Making/Maintenance-which meets the first and third Wednesdays of each month (see our calendar). Members and the public alike are welcome to visit, learn more about the opportunities, bring in a telescope for assistance, begin a telescope from scratch or just ask questions.
Check the UNM Observatory website or call their Hotline number 277-1446 after 3:00pm on Friday to check for closures or for more information. Parking and admission are both free. We thank you in advance for arriving before dark to park to avoid directing light to the observing area and for using only red lights after dark to preserve night vision.
