An ex-CIA is the point man for a government organization dedicated to time traveling to correct errors that occurred in the previous week.
The show makes reference to "Element 115" as the fuel for the Sphere. Between July 14 and Aug. 10, 2003, element 115 was discovered by Scientists from the Glenn T. Seaborg Institute and the Chemical Biology and Nuclear Science Division at the Lawrence Livermore National Laboratory, in collaboration with researchers from the Joint Institute for Nuclear Research in Russia (JINR). It has an atomic mass of 295, with 180 neutrons, and isotopes with atomic masses of 287 and 288. The total quantity produced was four atoms. As of 2004, it has not been officially named, but has a provisional designation of Ununpentium. In the periodic table, it appears in the same column as the elements Nitrogen, Phosphorus, Arsenic, Antimony and Bismuth and shares many of their chemical properties. The use of element 115 in this series is a reference to an interview with Robert Lazar, who claimed to be a former Area 51 worker. In this interview, he said that Ununpentium was an element used by UFOs to produce anti-gravity effects.
Element 115 was officially recognized by the IUPAC on December 30, 2015. Its discoverers were given the chance to name the element. They suggested langevinium (after Paul Langevin, a 20th-century French physicist) and moscovium (after the Moscow Oblast, where the discovering laboratory in Dubna is located). The latter was formally accepted on November 28, 2016. Its assigned atomic symbol is "Mc".
Lt. Frank Parker:
Ever wish you could live your last week over again? Well, my name's Frank B. Parker and I get to all the time. I work for a secret government project experimenting in time travel. When things really get messed up, I'm the guinea pig they send back ...
While it is revealed in Season 1 Episode 2 that Frank Parker (or whoever pilots the sphere) disappears, it is not explicitly stated what happens to the sphere. However, throughout the series, recovery of the sphere from random locations throughout the world was discussed and depicted. Also, an empty cradle was depicted during backsteps. As the Pilot disappears, it makes logical sense that anything or anyone else that makes the backstep would disappear as well.
The credits at the end of the episode "The Devil and the Deep Blue Sea" include an acknowledgment and thanks for the Canadian naval Base CFB Esquimalt, and the officers and crew of the HMCS Huron, for their cooperation in the making of the episode.
