It’s a Bird! It’s a Plane! It’s a Mobile Infrared Observatory! NASA’s SOFIA Boeing 747SP is Heading to ERAU’s Daytona Beach Campus

Collin Anderson News Editor Last week, Embry-Riddle announced that NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) aircraft is coming to Daytona Beach International Airport, and more specifically Embry-Riddle, next week and will be here

from Oct. 2 until Oct. 6. The SOFIA aircraft is a modified Boeing 747SP with a 2.5-meter telescope in the rear of the aircraft weighing in at 17 tons alone. It is based at NASA's Armstrong Flight Research Center in Palmdale, California. According to their website, the SOFIA Program Office is at NASA

Ames Research Center in Moffett Field, California. SOFIA is currently a joint project of NASA and DLR, the German Aerospace Center. SOFIA is visiting as part of its first scientific mission to be flown over the Atlantic Ocean. SOFIA will be observing Neptune's largest moon, Triton. Tri-

ton is about 1,700 miles in diameter making it larger than Pluto. According to Embry-Riddle, Triton’s surface is comprised of mostly frozen nitrogen that has been sculpted by winds and “cryogeysers” that spew material onto the surface. Triton will pass by and conceal a star called UCAC4 410-143659. The optimal way to capture this event is with a mobile research facility such as SOFIA. SOFIA is unique not solely due to its mobility, but it is also able to fly above the Earth's layer of water vapor between 39,000 and 45,000 feet. This is an important attribute because water vapor in the atmosphere shields the Earth from most of the infrared light from celestial bodies. Adding to SOFIA’s unique history, it has captured infrared images of Jupiter, the 2014J supernova, rings of gas and dust that measure seven lightyears in diameter around a supermassive black hole at the Milky Way’s center.

SOFIA will not be open to tours for the general public. However, the Embry-Riddle community will have an exclusive opportunity to tour SOFIA on Wednesday, Oct. 4 between the hours of 10:30 a.m. and 4 p.m. Motor coaches will transport students and fac-

ulty from the ICI Center to SOFIA and back. The exact time of landing is unknown as of yet, but SOFIA can be tracked on FlightAware or FlightRadar24 under the tail number N747NA. SOFIA should arrive at KDAB on the 2nd of October.
