"We must prepare for the danger of an asteroid collision with the Earth, otherwise we will end up like the dinosaurs"

This is what Professor Daniel Shiraz from the University of Colorado, Boulder, said at the 54th annual Israeli Conference on Aerospace Sciences at the Technion

"In view of past collisions between asteroids and the Earth, we are aware of the danger of such collisions and must prepare accordingly - so that we do not end up like the dinosaurs." So said Professor Daniel Scheeres from the University of Colorado, Boulder, after whom the asteroid 8887 Scheeres discovered in 1994 was named. He spoke at the Technion, at the 54th annual Israeli Conference on Aerospace Sciences.

"The asteroids are remnants from the formation of the solar system, so they teach us a lot about the beginning of the system's existence and its mechanics," he explained. Asteroids are relatively small bodies - their size ranges from the diameter of a grain of sand to 1,000 kilometers. These bodies are constantly changing under the influence of solar radiation and interactions with stars and other bodies. "NASA invests heavily in missions aimed at studying asteroids, and landing on an asteroid could serve as an excellent 'pilot' for a future landing on Mars," said Professor Shiraz. He talked about his involvement in OSIRIS-Rex - a mission in which a spacecraft will be launched in 2016 and return in 2023, and will bring to Earth extensive information about the asteroid Bennu and the mechanics of the formation of the solar system.

As part of the conference, a student project competition was held. Noam Naaman and Doreen Abseid, from the Technion's Faculty of Aeronautics and Space Engineering, won first place in the "Research/Experimental Project" category for a unique study they conducted under the guidance of Dr. Yossi Elimelech. The two studied the effect of the shedding of wings and their replacement on the flight capabilities of the hummingbird. This research has implications Applications in the field of small aircraft. "This is a research project we did as part of the degree The first one," said Noam, who has already held the title of Israeli champion in the 3,000m steeplechase for five consecutive years, "he demanded more hours from me than I spent on all the other titles."

Doreen, his partner in the winning project, said that "the research project was the most difficult task in the degree. During Hanukkah, we sat for days and nights in the dark room, where we made the observation. It was a great effort, it was a great excitement to reach the competition and win first place."

Mrs. Armona Brendel, a graduate of the Technion and chief system engineer at Elbit Systems, described at the conference the C-MUSIC (TM) PROGRAM project, within the framework of which Elbit develops systems to protect civilian aircraft against anti-aircraft missiles. , Kenya, on November 28, 2002. The two shoulder-fired missiles that were fired at the plane did miss it, but This event was a significant turning point in the threat to civilian aircraft. "The program was launched in 2009. Our system, based on a laser, is designed to protect the aircraft during takeoff and landing. Military defense systems against anti-aircraft missiles already existed before, but the adaptation to the civilian market is very complicated due to various aspects such as budget, weight, safety and civil aviation regulations."

The innovative system of Elbit Systems is based on the detection of the missile and the launch of laser radiation that diverts it from its trajectory, and this within a few seconds. The first test flight, conducted in June 2013, was crowned a success.

"The Faculty of Aeronautics and Space Engineering was the first faculty to open its doors on the Technion's current campus," said Technion President Professor Peretz Lavi, who opened the second day of the conference. "The press ridiculed and asked: 'What will they fly over Carmel - kites?' Today, there is no doubt that it was an excellent decision. This is where the people who established this field in Israel came from, and brought it to the level of a national league."

About five hundred engineers, scientists and experts in the fields of aeronautics and space in Israel and around the world participated in the annual Israeli conference for aviation and space sciences. The Chair of the Articles Committee, Professor Daniela Reva from the Faculty of Aeronautics and Space Engineering at the Technion, said that during the conference new research results were revealed and technological achievements and future developments were presented. The conference was organized by the Technion, Tel Aviv University, Ben Gurion University, Israel Aerospace Industries, Rafael , the Israel Military Industry, Elbit, the Israel Aerospace Sciences Association, and the Ministry of Defense.
