In 2005, Lowell Observatory in Flagstaff, Arizona received $10,000 in Tourism Cares Worldwide Grant funding. Established in 1894, Lowell Observatory is a National Historic Landmark. The refracting telescope was built in Boston and then hauled to Flagstaff by train. Percival Lowell used this telescope to study Mars. In the early 1900s, V. M. Slipher discovered the first evidence that our universe is expanding, During the 1960s, the telescope and observatory were used to create base drawings for a Moon mapping project sponsored by the U. S. Air Force. It was there that Apollo astronauts got their first good views of where they would make their historic landing on the Moon. The grant funding helped the observatory make major improvements to these permanent interpretive exhibits. As a result they became more interactive and dynamic, while simultaneoulsy preserving important scientific and human history.
