The chances are good that electric propulsion will play a role, and a company called MSNW is at the cutting edge of that technology.<\/p>\n<p>The director of propulsion research for Redmond, Wash.-based MSNW, Anthony Pancotti, will take a share of Capitol Hill\u2019s spotlight on Thursday during a hearing organized by the House Subcommittee on Space. And he expects to learn as much from his encounter with lawmakers as they\u2019ll learn from him.<\/p>\n<p>\u201cWe\u2019re all curious about what Congress wants to talk about,\u201d Pancotti told GeekWire from Washington, D.C., on the eve of the hearing.<\/p>\n<p>MSNW is already nearly two years into its work on a high-power electric propulsion thruster for a NASA program called Next Space Technologies for Exploration Partnerships, or NextSTEP. The program\u2019s aim is to accelerate the development of advanced propulsion systems for space exploration.<\/p>\n<p>Aerojet Rocketdyne\u2019s Redmond office is also part of the NextSTEP program. For years, Aerojet has been working on electric propulsion systems, including a 4.5-kilowatt thruster subsystem that played a key role in the Pentagon\u2019s AEHF satellite system.<\/p>\n<p>Electric propulsion isn\u2019t suited for launching payloads from Earth\u2019s surface, but it works like a charm for moving payloads around in space. NASA has already used the technology on small robotic probes such as Deep Space 1 and Dawn. Now the space agency wants to scale it up for heavier-duty applications.<\/p>\n<p><iframe title=\"NASA Jet Propulsion Laboratory - Ion Propulsion Advance Technology To Power Spacecrafts [720p]\" src=\"https:\/\/www.youtube.com\/embed\/pDO4uhqehK0?start=32&amp;feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\" data-ratio=\"0.5625\" data-width=\"800\" data-height=\"450\" style=\"display: block; margin: 0px; width: 800px; height: 450px;\"><\/iframe><\/p>\n<p>NextSTEP\u2019s objective is to boost the power capacity of electric propulsion thrusters from around 5 kilowatts to beyond 50 kilowatts. MSNW and Aerojet are both working on 100-kilowatt thrusters.<\/p>\n<p>\u201cThis is a pretty big jump,\u201d Pancotti said.<\/p>\n<p>When MSNW began its work on the $1.5 million contract, NASA was planning to use electric propulsion to send a probe out to an asteroid and bring a piece of it back for study.<\/p>\n<p>This year, NASA set aside its Asteroid Redirect Mission, also known as ARM. But the space agency still wants to capitalize on electric propulsion for other journeys beyond Earth orbit \u2013&nbsp;including cislunar space, which is the region of outer space in the vicinity of the moon.<\/p>\n<p>\u201cThe technology does transition very well from ARM to cislunar space, or directly to Mars,\u201d Pancotti said. \u201cIt will be very exciting to see which direction we head.\u201d<\/p>\n<p>MSNW\u2019s thruster electromagnetically forms, accelerates and ejects high-density, magnetized blobs of plasma. The big advantage of electric propulsion is that it can produce steady thrust with less fuel than a conventional chemical rocket requires.<\/p>\n<p>With a conventional propulsion system, \u201ca couple percent of the total mass is going to make it to your destination&nbsp;\u2013 let\u2019s say the surface of Mars,\u201d Pancotti said. In contrast, an electric propulsion system could transfer 70 percent of total mass from low Earth orbit to a deep-space destination.<\/p>\n<p>\u201cThat\u2019s a huge game changer,\u201d Pancotti said.<\/p>\n<figure id=\"attachment_345490\" aria-describedby=\"caption-attachment-345490\" style=\"width: 630px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full-width wp-image-345490\" src=\"https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2017\/06\/170628-msnw-630x379.png\" alt=\"MSNW thruster\" width=\"630\" height=\"379\" srcset=\"https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2017\/06\/170628-msnw-630x379.png 630w, https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2017\/06\/170628-msnw-768x463.png 768w, https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2017\/06\/170628-msnw.png 1192w\" sizes=\"(max-width: 630px) 100vw, 630px\"><figcaption data-nosnippet=\"\" id=\"caption-attachment-345490\" class=\"wp-caption-text\">MSNW\u2019s thruster is being tested at the company\u2019s lab in Redmond, Wash.

For the NextSTEP tests, MSNW will be using inert xenon and argon gases \u2013&nbsp;but theoretically, it could use water from an asteroid, or carbon dioxide from the Martian atmosphere.<\/p>\n<p>MSNW plans to conduct a dry run of the thruster without propellant, to show that it can stand up to the heat that\u2019s generated by the device. \u201cOne hundred kilowatts, you\u2019re talking about a lot of heat,\u201d Pancotti said. The thermal demonstration could take place as early as August, he said.<\/p>\n<p>Thursday\u2019s hearing, which focuses on the strategic choices and options for in-space propulsion, is scheduled to begin at 10 a.m. ET (7 a.m. PT).<\/p>\n<p>In addition to Pancotti and Aerojet\u2019s Joe Cassady, the experts scheduled to testify include former NASA astronaut Franklin Chang-Diaz, founder and CEO of Ad Astra Rocket Company; Mitchell Walker, chair of the propulsion technical committee at the American Institute of Aeronautics and Astronautics; and two of NASA\u2019s associate administrators, Bill Gerstenmaier and Steve Jurczyk.<\/p>\n<p><strong>Update for 9:45 p.m. PT July 1:<\/strong> The subcommittee\u2019s chairman, Rep.
