Russian radio amateur Dmitry Pashkov doubted the test of the innovative water engine on the American microsatellite MOMENTUS-X1.
“Based on open data from the North American Air Defense Command (NORAD), MOMENTUS-X1 did not perform any maneuvers in orbit,” Pashkov wrote on his website.
According to the program documents given by the radio amateur, the device had to lower its orbit within the framework of tests of the innovative demonstration microwave electrothermal engine on a water-based Momentus Vigoride.
At the same time, the developer of the device, the American company Momentus Space, in the American media reported on the successful test of the water-based engine.
The company was founded by Russian entrepreneur Mikhail Kokorich. The company has raised 34 million US dollars for technology development and testing. This satellite is the first 16U CubeSat in the world. After the launch of the satellite and statements about successful engine testing, the company announced its plans to enter the IPO, valuing itself at 1.2 billion dollars.
MOMENTUS-X1 satellite was launched on July 5, 2019, from the Vostochny launch site on the Soyuz-2.1b launch vehicle.
