element 115 – propulsion of extraterrestrial craft

Jeremy Corbell’s previous documentaries profiled a surgeon who removes extraterrestrial implants and investigated Robert Bigelow’s Skinwalker ranch, which is an alleged hotbed of UFO activity.

Corbell’s documentary, Bob LazarArea 51 and Flying Saucers, touches on other facets of Lazar’s story, such as his claim in 1989 about use of element 115—also known as moscovium—for the propulsion system of the extraterrestrial craft. When Lazar first came forward with his story about UFOs in Nevada, element 115 hadn’t been created in a lab yet. In 2003, however, Russian scientists synthesized the element for the first time.

Element 115 is an incredibly radioactive substance and one of the heaviest elements ever discovered. To date, only four moscovium isotopes have been produced in a lab, each popping into existence for a few fractions a second. According to Lazar, however, the extraterrestrial craft he worked on used a stable version of element 115 to warp gravity around the craft and propel it forward.

Moscovium is a radioactive, synthetic element about which little is known. It is classified as a metal and is expected to be solid at room temperature. It decays quickly into other elements, including nihonium.

The element had previously been designated ununpentium, a placeholder name that means one-one-five in Latin. In November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name moscovium for element 115.

The IUPAC also approved names for elements 113 (nihonium, with atomic symbol Nh), 117 (tennessine, Ts) and 118 (oganesson, Og).

Names for elements 115 and 117 were proposed by their discoverers at the Joint Institute for Nuclear Research in Dubna, Russia; the Oak Ridge National Laboratory in Tennessee; Vanderbilt University in Tennessee; and Lawrence Livermore National Laboratory in California. Both element names, moscovium and tennessine, honor regions where experiments linked to creating the elements took place.

Just the facts

Atomic Number: 115
Atomic Symbol: Mc
Atomic Weight: [288]
Melting Point: Unknown
Boiling Point: Unknown


Moscovium was discovered in 2003 and officially announced on Feb. 2, 2004. It was created and announced by scientists at the Joint Institute for Nuclear Research in Dubna, Russia, and scientists at the Lawrence Livermore National Laboratory in the United States.


Moscovium has four isotopes with known half-lives, the most stable of which is 289Mc, with a half-live of about 220 milliseconds.

The atomic weight for manmade transuranium elements is based on the longest-lived isotope. These atomic weights should be considered provisional since a new isotope with a longer half-life could be produced in the future.

Sources of moscovium

To make moscovium, the scientists in Russia and the United States bombarded atoms of americium with ions of calcium in a cyclotron. This produced four atoms of moscovium.

Uses of moscovium

Only a few atoms of moscovium have ever been made, and they are only used in scientific study. It is used to make nihonium.
