BERLIN, Germany, 14 November 2016 (Press Release) – During a press event today at the Museum für Naturkunde (MfN) (Museum of Natural History) in Berlin, a major campaign was launched to support scientific missions designed to increase our knowledge of asteroids and near Earth objects (NEOs), in particular ESA’s Asteroid Impact Mission.

The campaign, “I Support AIM (www.isupportaim. com) was initiated by the co-founders of Asteroid Day, the global movement to protect the world from dangerous Asteroids, and the Observatoire de la Côte D’Azur, one of the most important research institutions worldwide in the areas of biological and geological evolution and biodiversity.

During the press conference, organizers released an open letter signed by more than 100 small body scientists supporting increased knowledge of Near Earth Objects (NEOs) and space missions necessary to protect Earth from dangerous NEO impacts.

The letter, now open for public signature, is available here: www.isupportaim.com/letter

“More than 100 prominent scientists from around the world have signed a letter in support of AIM because studying NEOs cannot be underappreciated and the AIM mission is core to gaining the knowledge we need to detect and ultimately deflect dangerous asteroids headed towards Earth,” said Grig Richters, Co-Founder, Asteroid Day.

NEOs are left over matter from the formation of planets and range in size from a few meters to tens of kilometres. As with Earth, NEOs orbit the Sun and sometimes come dangerously close to Earth’s trajectory. AIM will determine whether a kinetic impactor is able to deflect such a small body, when Earth is threatened.

“New NEOs are now being discovered at the rate of some 4 per day”, said Alan Harris, Senior Scientist, German Aerospace Center DLR. “We need a coordinated international strategy for near-Earth object impact mitigation!”

Within the larger AIDA international collaboration, AIM will help to assess NEOS by characterizing for the first time, the small moon of a binary asteroid, as highlighted by Stephan Ulamec, Philae lander manager and AIM co-investigator (DLR): “The combined AIM and DART missions, AIDA, will give us the unique possibility to test our capabilities to deflect an asteroid, combined with fascinating science!“

AIM is a new interdisciplinary mission that is set to become humanity’s first mission to a binary asteroid system. It should launch in 2020 and is perfectly design to gather all data necessary to validate a technique called asteroid deflection.

AIM will then reach the binary near-Earth asteroid (65803) Didymos in mid-2022, after a 18-month flight. There, it will wait for NASA’s DART Spacecraft that will impact the smallest of the two asteroids, in an attempt to deviate its orbit.

AIM will able to carry out detailed before-and-after observations of the asteroid’s structure as well as its orbit, fully documenting the consequences of DART’s kinetic impact. This would be the first ever attempt to deflect the orbit of a Solar System body.

“It is now that we have the knowledge about the surface of comets and asteroids from space missions as Rosetta and Dawn – and based on this experience we are best prepared for a mission on asteroid deflection. “ said Holger Sierks, Principal Investigator Rosetta/OSIRIS, Planets and Comets Department, Max Planck Institute for Solar System Research.

“Simulations of asteroid deflection by impact are only as good as the knowledge we put into them. With AIM and DART, we have the unique opportunity to test our simulations and feed them with new knowledge about the asteroid’s responds on impact”, echoed Kai Wünnemann, Head of Division Impact and Meteorite Research at MfN.

AIM will also demonstrate advanced new technologies for use in future planetary missions and also pave the way to new types of deep-space missions using CubeSats for riskier operations.

Of the NEOs so far discovered, there are more than 1700 asteroids currently
considered hazardous. Unlike other natural disasters, this is one we know how to predict and potentially prevent with early discovery. As such, it is crucial to our knowledge and understanding of asteroids to determine whether a kinetic impactor is able to deflect the orbit of such a small body, in case Earth is threatened. This is what AIDA will help us assess.

About the Côte d’Azur Observatory

The Côte d’Azur Observatory (OCA) in Nice, France, is a public research centre for Astronomy and Earth sciences. OCA hosts 3 research laboratories, and among them the Lagrange Laboratory of CNRS (National Centre for Scientific Research), which focuses on research in instrumentation, ground/space-based observations and theoretical/numerical modelling in the fields of planetology, fluid mechanics, plasma and solar physics, and cosmology.

About Asteroid Day

Asteroid Day is a global movement to increase public awareness of potential asteroid collisions and the means to protect Earth. It was co-founded in 2015, by Dr. Brian May, astrophysicist and lead guitarist for the rock band Queen, COO of B612 Danica Remy, Apollo astronaut Rusty Schweickart, and German filmmaker Grig Richters. Asteroid Day is held on 30 June each year to mark Earth’s largest asteroid impact in recorded history, the Siberia Tunguska event, which devastated over 2000 square km, the size of any major metropolitan city.
