Skybox Imaging is building a constellation of high-resolution Earth imaging micro-satellites in order to revolutionize access to information about the changes happening across Earth. In 2013, Skybox launched its first satellite, SkySat-1 as the pathfinder to a constellation of small spacecraft. We begin with a high-level overview of Skybox Imaging...

To further develop and demonstrate the applicability of liquefying-fuel hybrid rocket technology to low-cost launch applications, a small team of engineers is developing a medium-scale liquefying-fuel hybrid sounding rocket using storable propellants (paraffin wax and N2O) that will carry a 5 kg payload to the edge of space. This rocket, known as P...

The dynamic behavior in a hybrid rocket motor is established by a number of complicated nonlinear physical and chemical processes which could potentially lead to multiple equilibrium points for the motor operation. Depending on the stability of the equilibrium points, switching from one mode to the other during the course of the motor operation is...

This paper addresses the safety issues associated with the oxidizer nitrous oxide (N2O) with emphasis on propulsion systems. Even though N 2O is a widely used energetic material, the number of decomposition related accidents are quite limited due to its abnormally slow decomposition kinetics. However hazards do exist especially in propulsion system...

Self-pressurizing propellants have some very attractive attributes for the propulsion system designer. The high vapor pressure at low temperatures of oxidizers such as nitrous oxide and fuels such as ethane allow these propellants to be used efficiently without the need for an external pressurant and the associated complexity and mass. However, per...

The purpose of this study was to characterize the regression rates of three traditional hybrid rocket fuels along with one novel fuel using nitrous oxide as the oxidizer. In order to complete these tests, a robust test facility was developed for use in this study as well as in future hybrid rocket programs at Stanford University. This stand allowed...
