![]() ![]() Both classes of propulsion technologies can perform very well for CubeSats and should be evaluated for any potential system. Electric or chemical – This is a big debate and beyond this article to go into in detail.Specific impulse – What specific impulse values are required for your CubeSat and intended applications?.Size and weight – Will it fit? Is it too heavy? The physical volume (usually expressed in CubeSat units / U) and on-Earth weight determine what other components can be used in the unit and impact transport and launch costs.Some of the potential key specifications and performance criteria to evaluate are: Now you’re armed with the knowledge of what the thruster needs to do, work alongside and fit within, you can make an informed decision from the available products, based on your required performance characteristics. We also provide an overview of a number of propulsion products on the market, listed on the satsearch platform to help you select the best option. To help navigate these criteria, in this article we look at some of the factors that should be taken into account to make this decision. The rapid growth of the NewSpace sector has led to greater use of modular components, such as CubeSat thrusters, while electronic miniaturization is also enabling new satellite setups and capabilities that need to be considered. Selecting the most appropriate thruster product for a CubeSat can be a tricky challenge, but is a critical step for any mission or service requiring inspace maneuverability and control. Alternatively, if you’d like to list your products and services on satsearch, get started here. In this article, we provide a gentle primer to the topic of selecting a thruster for a smallsat mission, and give an overview of some of the propulsion products making waves within the global marketplace for space.ĭo you know of any smallsat thrusters that we’ve missed? Please drop us a note at or on Twitter. Over the past decade, there has been an explosion of activity in the smallsat propulsion world, driven by technology breakthroughs, industry commercialization, and private investment. This is particularly important for the slew of LEO and MEO constellations currently being developed, as constellation control will be an important factor in the success of these ventures. According to officials, the incident delayed the movie's filming schedule.There is growing demand for in-space propulsion systems that enable small satellites to achieve attitude and orbit control, orbital transfers, and end-of-life deorbiting. AT that time, NASA stressed that such incidents were rare.Ī Russian film crew that traveled to the ISS on 5th October later returned to Earth aboard the Soyuz spacecraft that misfired. In July, thrusters on Russia's Nauka module fired "uncontrollably," reorienting the ISS by about 45 degrees and taking at least an hour to regain control. In a statement, a NASA spokesperson said the Soyuz thruster test firing unexpectedly continued beyond the point when its was planned to end. The incident began when cosmonaut Oleg Novitsky was testing the engines of the spacecraft, while it is docked with the station. NASA and Roscosmos ground teams tried to regain control of the station about 30 minutes after it lost positioning control at 5:13AM ET. INTERNATIONAL SPACE STATION: The International Space Station (ISS) unexpectedly tilted after a faulty test firing of thrusters on a Russian Soyuz MS-18 spacecraft, the second such incident aboard the ISS.Īccording to a statement from Russia's Roscosmos space agency, those aboard the ISS were never at risk. ![]()
