New findings reveal deposits on Mars that could be interpreted to be ice-rich may contain little or no ice at all, based on an analysis of radar sounder data for Meridiani Planum—an area on the planet’s equator being explored by the Opportunity rover. This new insight into Meridiani Planum may help identify areas with and without accessible water ice, a resource critical to future human exploration and possible colonization of Mars. The paper, “Radar Sounder Evidence of Thick, Porous Sediments in Meridiani Planum and Implications for Ice-Filled Deposits on Mars,” is published in the September issue of Geophysical Research Letters by lead author and Smithsonian senior scientist Thomas R. Watters.

The Smithsonian’s National Air and Space Museum launches its Fall 2017 GE Aviation Lecture Series Sept. 7 with reflections from father and daughter John Penney and Heather “Lucky” Penney on their experiences on 9/11.

The Smithsonian’s National Air and Space Museum will present “Mars Day!,” its annual tribute to the Red Planet Friday, July 21, from 10 a.m. until 3 p.m. at the museum on the National Mall. Organized by the museum’s Center for Earth and Planetary Studies, the event enables visitors to interact with its team of staff scientists and experts from NASA.

The Smithsonian’s National Air and Space Museum will serve as a major source of information, educational activities and experiences in the Washington, D.C., area on and around the total solar eclipse Aug. 21, an event that has not occurred in the U.S., coast-to-coast in nearly 100 years. “Your Eclipse” family days will be held at the museum on the National Mall July 8 and at the museum’s Steven F. Udvar-Hazy Center in Chantilly, Va., July 15. On the day of the eclipse, programming will be held at both buildings and online. There will be excellent viewing opportunities at the Phoebe Waterman Haas Public Observatory just outside the entrance to the museum in Washington. The museum’s popular 30-minute live webcast, “STEM in 30,” will broadcast from Liberty, Mo., which is in the “path of totality,” the narrow path across the country where the moon’s shadow will completely eclipse the sun.

The National Air and Space Museum’s Steven F. Udvar-Hazy Center in Chantilly, Va., will host family-friendly activities throughout the summer to meet every staycationer’s needs. The popular “Innovations in Flight Family Day and Aviation Display” will return June 17. Visitors will learn about science behind the total solar eclipse that will cross the United States later this summer at Your Eclipse family day July 15. Movies, story times and Smithsonian TechQuest round out the summer activities and ensure there is something for every age group.

This year’s Charles A. Lindbergh Memorial Lecture at the National Air and Space Museum features Reeve Lindbergh, daughter of Charles Lindbergh, May 18 at 8 p.m. May marks the 90th anniversary of Charles Lindbergh’s historic solo flight from New York to Paris in the “Spirit of St. Louis.” Lindbergh will honor her parents in her remarks, both of whom had a lasting impact on the world of aviation.

This year’s Space Day at the Smithsonian’s National Air and Space Museum will take place Saturday, May 13, from 10 a.m. to 3 p.m. Sixty years after the launch of Sputnik, visitors of all ages are invited to celebrate the space age and learn how space activities affect their lives today. This family day at the museum in Washington, D.C., will include talks by experts, demonstrations and hands-on activities for all ages.

The National Air and Space Museum will present the next lecture in the GE Aviation Series May 3 with Jon and Patricia Sharp, a married couple who design, build, test and race their own planes. In “Chasing the Dream, Not the Competition,” the Sharps will talk about their original aircraft, Nemesis, the most successful aircraft in air-racing history, and the records they have set and races they’ve won. The lectures is free to the public, but tickets are required. It will begin at 8 p.m. at the museum in Washington, D.C., and will be webcast.
