Small Business Launches Down-to-Earth Products via NASA SBIR Program

Through the SBIR program, DSSP developed a multi-pulse solid rocket motor for NASA that will enable stabilized interplanetary flight for small satellites. Another of DSSP’s core innovations with roots in the SBIR program is already having an even greater impact. Originally proposed to fuel a microsatellite thruster for Earth-observation missions, DSSP’s HAN-based green electric monopropellants (GEM and AF-M315E) technology is powering larger satellites, enhancing downhole oil and gas recovery, and much more. Highly insensitive to ignition by spark, flame, or shock, GEM-based innovations are stable, non-toxic, and more controllable than conventional propellants.

Small Business Technology Enables Safer Lunar Landings & Longer Lunar Missions

Masten Space Systems leveraged NASA SBIR/STTR solicitations to identify and respond to challenges with establishing a sustainable presence on the Moon. The company partnered with the program to study the effects of rocket engine plume impingement and blast during lunar landings and launches, and to develop a metal oxidation warming system (MOWS) technology, resulting in $2.8 million in funding from the NASA Tipping Point program to enhance the capability of the MOWS technology. Masten participated in the NASA SBIR/STTR I-Corps training program to help identify commercial uses for these technologies.

The Voyagers: Risky Business Beyond the Heliopause

Both 43 year old Voyager spacecraft have entered interstellar space while continuing to return exciting and unique scientific data. While it is possible that both spacecraft might operate until 2030, many components are presenting problems just as resource margins are eroding to critical levels. The flight team is managing risks to almost every significant sub-system on the vehicles and many of these risks are interconnected. This paper offers a summary of the major issues encounter by the flight team and how each problem is being managed.
