SpaceX Falcon 9 “Space Mouse” Explained

Once upon a time there was a giant mouse on the Falcon 9 rocket.

SpaceX launched the manned SpaceX Dragon capsule on Sunday, May 31st 2020. Online spectators are seeing a mouse crawling around the expansion nozzle. Is this about a mouse on the Falcon 9 rocket?

False, we do not see a mouse near the expansion nozzle of the Falcon 9 rocket but a by-product of leaking liquid oxygen. The Merlin is developed by SpaceX and liquid oxygen next to Kerosene (RP-1) are used as propellants. The white clumps can also be seen during the 2019 CRS-19 mission on the Merlin and in 2017 during the SpaceX Dragon mission. This is known as the Leidenfrost effect.

“Looks like a MOUSE hitchhiked a ride on Elon Musk’s SpaceX rocket launch today,” says a Twitter user. In the video below, a large audience of people claims the white sliding clump is a mouse.

Dragon/CRS-19

In the 2017 SpaceX Dragon mission and the CRS-19 Mission of December 5, 2019 in which the Falcon 9 rocket landed in the Atlantic ocean, clumps of liquid were sliding and dropping from Merlin’s expansion nozzle. Witness, watch the video below.

Illogical

No living creature can survive conditions without oxygen and can stand the catastrophic heat. The diameter of the expansion nozzle is at least 1.25 m (4.1 ft) and the average length of a Deer Mouse is 9.6 cm. This means the creature in the video must be a giant mouse because the ratio does not match the average mouse living in the United States.

The white clumps is a by-product of liquid oxygen also known as the Leidenfrost effect.

The Leidenfrost effect is the phenomenon whereby a liquid that comes into contact with a surface that is much hotter (warmer than the Leidenfrost point) forms a thermally insulating vapor layer that prevents the liquid from boiling.
