circumplanetary disk (13.253)

Although the suggested existence of a ring-planet dates back to nineteen century observation notes by William Herschel, the definitive discovery of Uranius’ coherent orbital debris fields occurred by fortuitous accident on this day in 1977 by astronomers aboard the Gerard P Kuiper Airborne Observatory, a customised Starlifter jet transporter commissioned by NASA as a platform for research in infrared astronomy. Debuted as the civilian version of defence contractor Lockheed-Martin C-141, this high-altitude plane could rise above terrestrial interference equipped with a conventional telescope and spectrometry instruments the programme was also witness to the transmutation of elements through stellar fusion by studying , organic compounds in the great void of space as well as studying the mineral makeup of Mercury. Active for twenty years, the project was eventually retired in 1995.
