NASA scientist Dr. Geoffrey A. Landis will discuss the Mars Exploration Rovers, and the past and future exploration of Mars by robots and humans, in a free public presentation at the Metroparks Rocky River Nature Center. The talk will take place at the monthly meeting of the Cuyahoga Astronomical Association on Monday, July 13, at 7:30 PM.

Dr. Landis is a physicist and an award-winning author who was one of the principal investigators on NASA's Mars Pathfinder program.

His work centered on the solar power systems for the rovers, Spirit and Opportunity, which are currently exploring Mars.

The Rocky River Nature Center is located at 24000 Valley Parkway in North Olmsted.

Major change afoot at Letha House Park

**Construction is well underway at Letha House Park as seen in this view recorded June 6.** The work is the realization of longstanding plans created by the Medina County Park System. The small building in the center of the top photo is the CAA's Observatory, the larger is the Park System's "warm-up" building. A new gravel path encircles the park's large pond and entry to the area has been moved to a drive off Richman Road to the north of Spencer Lake Road. The old entrance, just to the south of the Observatory, has been closed and an earthen mound built up in its place (see below). Photos by James Guilford.

**UPDATE:** There was no visible change when we checked on June 22 and the new Richman Road entrance was still closed to visitors.
