Rund 400 000 Kilometer hat das Signal zurückgelegt und die Erdatmosphäre durchquert, wenn es von Wissenschaftlern des Deutschen Zentrums für Luft- und Raumfahrt (DLR) analysiert wird. Das Ergebnis: “Der Einfluss der Atmosphäre ist weniger stark als erwartet, die Qualität des Signals ist sehr gut”, sagt Dr. Dirk Giggenbach vom DLR-Institut für Navigation und Kommunikation. Gesendet wurde das Signal vom Lunar Lasercomm Space Terminal (LLST) an Bord der NASA-Sonde LADEE (Lunar Atmosphere and Dust Environment Explorer), die seit Oktober 2013 um den Mond kreist. Damit wurde erstmals ein optischer Link nach seinem langen Weg durch den Weltraum vermessen. In Zukunft könnten beispielsweise Mond- oder planetare Missionen von dieser Art der Datenübertragung profitieren und Rover hochaufgelöste 3D-Aufnahmen in Echtzeit übermitteln. (more…)

He discussed the scientific returns of the Apollo missions and encouraged students to look to Apollo as a template for future human exploration of planetary bodies.

After the near-disaster of Apollo 13, NASA’s lunar exploration program stood at a crossroads. President Kennedy’s goal of landing a man on the Moon and returning him to Earth had been achieved, and many wondered, given the dangers, if it might be time to scrap Apollo. (more…)

How Yale’s newest graduates make their imprint on the world and on history will be determined by how well they handle fear and inspire faith, Oscar-winning actor Tom Hanks told the seniors in his Class Day address on May 22.

In the ceremony on the Old Campus, Hanks urged the soon-to-be graduates to begin their future by coming to the aid of the U.S. veterans of the Iran and Afghan wars, whose “faith in themselves is shadowed by the fear of not knowing what is expected of them next,” he said. (more…)
