Vigoride is a space tug that is under development by Momentus Space.[1] The total payload capacity that it can support to LEO is 750 kg.[2][3] Vigoride is capable of changing orbital planes, inclination, and propelling spacecraft to up to 2 km/s. It also provides small satellite operators access to power, communications, and station keeping while with the tug.[1] Momentus states that the cost is roughly $15,000 per kg depending on the exact customer specifications.[4] Vigoride uses a microwave electrothermal thruster (MET) and water as the propellant. In 2019, the first test of the MET in space was completed and was deemed a success in a press release,[5] while the U.S. Securities and Exchange Commission accused it of misleading investors.[6] The maiden launch was originally scheduled for January 2021, but was delayed due to Momentus not being able to receive FAA approval before the launch.[7] On 22 March 2021, a Vigoride mock-up named Vigoride SC was launched in place of a functional Vigoride. In October 2020, the company stated that it had already booked 1.5 Vigorides out of the 3 planned to be launched in December 2021.[8] On 25 May 2022, Momentus launched its first Vigoride spacecraft aboard SpaceXTransporter 5 mission.[9]
