      The Satellite for Orbital Aerodynamics Research (SOAR) is a 3U CubeSat that has been designed to investigate the aerodynamic performance of different materials and perform demonstrations of aerodynamic attitude control ...
    • Ground-based experimental facility for orbital aerodynamics research: design, construction and characterisation 

      Oiko, Vitor; Roberts, Peter C.E; Macario Rojas, Alejandro; García-Almiñana, Daniel; García Berenguer, Marina; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (International Astronautical Federation, 2020)
      Conference lecture
      Restricted access - publisher's policy
      In very low Earth orbits (VLEO), below 450 km altitude, the aerodynamic properties of satellites are primarily determined by the flow regime, free molecular flow, and the interaction of atomic oxygen with the surfacesof ...
    • Intake design for an Atmosphere-Breathing Electric Propulsion system (ABEP) 

      Romano, Francesco; Espinosa-Orozco, J.; Pfeiffer, M.; Herdrichd, Georg H.; Crisp, Nicholas H.; Holmes, Brandon E.A.; Edmonson, Steve; Haigh, Sarah J.; Livadiotti, Sabrina; Macario Rojas, Alejandro; García-Almiñana, Daniel; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (2021-10)
      Article
      Open Access
      Challenging space missions include those at very low altitudes, where the atmosphere is source of aerodynamic drag on the spacecraft. To extend the lifetime of such missions, an efficient propulsion system is required. One ...
    • Investigation of Novel Drag-Reducing and Atomic Oxygen Resistant Materials in Very Low Earth Orbit using SOAR (Satellite for Orbital Aerodynamics Research) 

      Crisp, Nicholas H.; Macario Rojas, Alejandro; Roberts, Peter C.E; García-Almiñana, Daniel; García Berenguer, Marina; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (International Astronautical Federation, 2020)
