| 释义 |
Momentus X1 is a technology demonstration spacecraft designed and built by Astro Digital[1] for Momentus. It includes a Vigoride thruster, a Momentus' spacecraft propulsion technology,[2] which energizes water steam into a plasma using microwaves and ejects the super-heated propellant to efficiently produce thrust. The spacecraft will be launched in 2019 into a Sun synchronous orbit aboard a Soyuz rocket in a 16U CubeSat deployer designed and built by ECM Technologies of Berlin. The spacecraft bus is the Corvus-16 design shared with Landmapper-HD. The common satellite bus uses reaction wheels, magnetic torque coils, star trackers, magnetometers, sun sensors, and gyroscopes to enable precision 3-axis pointing without the use of propellant. Momentus plans to begin offering in-space transportation in 2020 to move payloads as large as 50 kilograms from low Earth orbit to geostationary transfer orbit, geostationary orbit, lunar orbit or other destinations.[3] References1. ^{{cite web|url=https://apps.fcc.gov/oetcf/els/reports/ViewExhibitReport.cfm?id_file_num=0698-EX-CN-2018&application_seq=87126 |title=Astro Digital Momentus X1 Orbital Debris Assessment Report |date=12 September 2018 |access-date=20 October 2018}} 2. ^{{cite web |url=https://spacenews.com/momentus-developing-water-engines/ |title=Introducing Momentus, a Silicon Valley startup focused on water plasma engines |publisher=SpaceNews |date=24 July 2018 |access-date=5 January 2018}} 3. ^{{cite web |url=https://spacenews.com/momentus-seed-round/ |title=Momentus raises $8.3 million for last-mile spacecraft delivery |publisher=SpaceNews |date=14 November 2018 |access-date=5 January 2018}} External links
