16P/Brooks
16P/Brooks, also known as Brooks 2, is a periodic comet discovered by William Robert Brooks on July 7, 1889, but failed to note any motion. He was able to confirm the discovery the next morning, having seen that the comet had moved north. On August 1, 1889, the famous comet hunter Edward Emerson Barnard discovered two fragments of the comet labeled "B" and "C" located 1 and 4.5 arc minutes away. On August 2, he found another four or five, but these were no longer visible the next day. On August 4, he observed two more objects, labeled "D" and "E". "E" disappeared by the next night and "D" was gone by the next week. Around mid-month, "B" grew large and faint, finally disappearing at the beginning of September. "C" managed to survive until mid-November 1889. No new nuclei were discovered before the apparition ended on January 13, 1891. The breakup is believed to have been caused by the passage of the comet within Jupiter's Roche limit In celestial mechanics, the Roche limit, a ...

SpaceShipOne Flight 16P
Flight 16P of SpaceShipOne was a spaceflight in the Tier One program that took place on September 29, 2004. It was the first competitive flight in the Ansari X PRIZE competition to demonstrate a non-governmental reusable crewed spacecraft, and is hence also referred to as the X1 flight. A serious roll excursion occurred during boost, so the flight did not achieve the expected altitude. However, it exceeded 100 km altitude, making it a successful X PRIZE flight. Scheduling X PRIZE rules required that the date and place of competitive flights be announced to the X PRIZE Foundation at least 60 days before the flight. Due to problems encountered during flight 15P on June 21, 2004, Scaled Composites did not immediately set a date for their competitive flights, suspecting that another test flight might be required. By July 7, 2004 Burt Rutan reported that the faults had been resolved and the next flights would be competitive. On July 27, 2004, the X PRIZE Foundation ...
