Help restore the Lowell Observatory Clark telescope

The Lowell Observatory in Flagstaff needs funds to restore the Clark 24″ telescope. They are trying to raise $250,000. Tucsonans can help by attending a Science Café at the SkyBar in Tucson.


Join the Arizona Experience at Sky Bar for a stellar evening in an astronomy themed science café. Lowell Observatory Outreach Manager Kevin Schindler will give a brief overview of the first observatory in the southwest and the plans to restore its 117-year old Clark Telescope– the telescope that discovered Pluto and recorded the first observations of the expansion of the universe. Today the Clark delights millions of public viewers. Find out what’s next for this historic treasure with the Restore the Clark campaign. Then, discover stargazing opportunities closer to home from the Tucson Amateur Astronomy Association and the GLOBE at Night global starcount.

What: Lowell Observatory and Arizona Astronomy Science Café
Where: SkyBar (536 N. 4th Avenue, Tucson)
When: April 25, 6:45 pm

On-street and lot parking is available.

The Clark telescope went into service at the Lowell Observatory in 1896. The Clark is one of the largest, most productive telescopes of its era and the first large telescope in the desert southwest of the United States. From 1961 to 1969, U.S. Air Force and Lowell cartographers made detailed maps of the moon based on observations made with the Clark Telescope. These maps were critical to the Apollo program, during which men landed on and studied the moon’s surface.

Often called the “People’s Telescope,” more than a million visitors have seen through the world-famous 24″ Clark Telescope in the past 20 years alone and it’s time for it to get a complete overhaul.
