ROV Meteorite HuntMarch 15 2017
On Monday, February 6, 2017, around 1:30 a.m. CST, a sonic boom shook residents of the Midwest as a bright green fireball streaked through the night sky. The sound was that of a meteor, nearly the size of a minivan, entering our atmosphere. After its fall to Earth, radar spotted the end of its journey over Lake Michigan, approximately 10 miles off the coast of Sheboygan, Wisconsin. Teen explorers from Chicago, led by scientists from the Adler Planetarium's Far Horizons program, The Shedd Aquarium, and The Field Museum, team up to take on this Underwater ROV Meteorite Hunt. Interested explorers wanted!Read background

The Adler Planetarium's Far Horizons Program has one mission: bring real space exploration down to Earth and into the hands of students, volunteers, and the public. On Monday, February 6, 2017, around 1:30am CST, a bit of space literally came to Earth and splashed down in our own backyard! Enthused by the hands on science this brings teens of Chicago, and the ability to collaborate with scientists across fields, the planning for this expedition began.
All parties involved understand the difficulty of this task, the "needle in a haystack" odds of this endeavor, and it drives us all the more to challenge teens of Far Horizons to engineer innovative ways to find and retrieve these meteorites. The STEM Professionals that work and volunteer in the Far Horizons Lab offer our team of teens helpful insights with their design concepts. Astronomers from The Adler Planetarium, and founding members of Far Horizons, Dr. Mark Hammergren and Dr. Shane Larson, enrich our student's understanding of the space science that brought this meteorite to our own back door.Dr. Philipp R. Heck, meteoritics expert from The Field Museum, has given our team insight into the possible make up of these meteorites and ways to detect them. Marc Fries, a scientist from NASA, and a colleague of Dr. Philipp R. Heck, calculated the radar data from the meteorite's path and has created a map that predicts locations of the meteorites (and size distribution), which will prove crucial in our hunt. We are also consulting with the Senior Research Biologist of the Shedd Aquarium, Dr. Philip Willink, to understand the environment of the lake bottom. Dr. WIllink is interested in this expedition, not only for a chance to find hunks of rock from space, but also to capture data of the lake floor that have not been clearly mapped in the past.
In 2003, a similar sized meteorite landed in Chicago, many of the larger fragments were around the size of softballs. The image below crashed through a Chicagoans roof and landed in their laundry! Dr. Philipp R. Heck assumes, from the size and color of the fireball that we are dealing with a similar size and make up of the Park Forest Meteorite (image seen below, Adler Planetarium).
This spring we'll continue to consult with experts as we prepare for our Meteorite Hunt scheduled for the summer (July/August). Everyone involved has a lot to learn from each other as the task of underwater meteorite recovery is rarely undertaken. We look forward to sharing with the Open Explorer Community, build Far Horizon's first OpenROV (to explore Far Horizons of the deep!) and welcome all interested explorers in the Great Lakes region who have access to equipment to join the search. We'll learn a lot from this journey, and hope you will too.
