As I was looking through NASA’s recent small business selection announcement for propulsion-related projects, I have found that the space agency has selected 29 Small Business Innovation Research and 8 Small Business Technology Transfer proposals for funding.
The proposals cover a wide range of areas, including in-space propulsion for CubeSats to technologies for new launch vehicles. Several proposals are also focused on in-space propellant depots.
A list of the selected projects with links to the proposals follows.
