A Mars Ascent Vehicle for potential mars sample return
Autor: Ashley C. Karp, John Dankanich, Joel Benito, Robert Shotwell
Publikováno v: 2017 IEEE Aerospace Conference.
This paper will cover the conceptual design of a Mars Ascent Vehicle (MAV) and efforts underway to raise the TRL at both the component and system levels. A system down select was executed resulting in a Hybrid Propulsion based Single Stage To Orbit (

The Iodine Satellite (iSat) Project Development through Critical Design Review (CDR)
Autor: Tyler A. Hickman, Lawrence Byrne, Derek Calvert, James Szabo, Hani Kamhawi, John Dankanich
Publikováno v: 52nd AIAA/SAE/ASEE Joint Propulsion Conference.
Despite the prevalence of small satellites in recent years, the systems flown to date have very limited propulsion capability. SmallSats are typically secondary payloads and have significant constraints for volume, mass, and power in addition to limi
