Chris Grainger, Vice President of Engineering

Mr. Grainger has more than twenty-five years of experience designing, testing, producing, and flying propulsion vehicles and other spacecraft. Prior to co-founding Parabilis, Chris served at SpaceDev Inc. (subsequently acquired by SNC) for more than fifteen years.
While at SpaceDev, Chris developed the spacecraft bus structure of CHIPSat, an innovative small satellite that was launched into orbit in 2003 and performed successfully until it’s decommissioning in 2008. He designed, built, and successfully tested the Space Shuttle-compatible Hybrid Maneuvering and Transfer Vehicle, designed to autonomously perform a two-burn circular orbit transfer. Chris also led the engineering team that designed, developed, and performed LV integration of Trailblazer, a small spacecraft delivered in 4 months from ARO and flown on SpaceX’s Falcon 1. He contributed substantially to the SpaceShipOne and other manned spaceflight programs, designing the main feed valves for the rockets in multiple vehicles.
Prior to SpaceDev Chris contributed at Integrated Space Systems, and also General Dynamics-Space Systems where he did substantial engineering work on the Atlas series of launch vehicles. His varying responsibilities included ordnance, thermal protection, separation systems, and fluid components.
Chris earned his BS degree in Mechanical Engineering from Cal Poly-Pomona, and his MS degree in Mechanical Engineering from San Diego State University. He holds numerous space-related patents.

Shannon Eilers, Principal Aerospace Engineer

Dr. Eilers is an accomplished propulsion and aerospace engineer with more than ten years of industry and research experience.
Prior to co-founding Parabilis, Shannon made substantial engineering and technical contributions at SpaceDev Inc. (subsequently acquired by SNC). Shannon led the team that designed, assembled, and successfully launched a 2000 lbf class hybrid sounding rocket demo, proving that hybrid technology could move from concept to flight in less than four months. His superb engineering skills were essential to both the SpaceShipTwo and other manned spaceflight propulsion programs.
Shannon earned his BS, MS, and PhD in Mechanical and Aerospace Engineering at Utah State University. One of his many accomplishments at USU was a CubeSat-scale hybrid motor prototype with a regeneratively-cooled aerospike nozzle and secondary injection thrust vector control.

Anthony Gemmill, Aerospace Engineer

Mr. Gemmill has more than seven years of aerospace experience and possesses a wide variety of valuable engineering skills. Prior to co-founding Parabilis, Anthony was an Aerospace Engineer at SpaceDev Inc. (subsequently acquired by SNC).
Anthony designed, developed, integrated, and tested numerous components on the hybrid propulsion system for Virgin Galactic’s SpaceShipTwo. He performed over 300 cold flow tests during feed system development, and many critical day-of-test installations and operations for the vehicle’s ground and flight testing. Anthony was a key technical lead on a 2,000 lb thrust hybrid sounding rocket demo that progressed from concept to flight in only 4 months. He led fluids, feed system design, and assembly for the program.
Anthony earned a BS degree in Aerospace Engineering from San Diego State University.
