Description:

• AeroCube-4 is a CubeSat technology demonstration mission within the PicoSat Program of The Aerospace Corporation, El Segundo, CA, USA. The AeroCube-4 CubeSat (a series of 3 spacecraft, is also designated as AC4-A, AC4-B and AC4-C). Two of the Aerospace-4 CubeSats were built for a national security agency. The third CubeSat was built for the for SMC/XR (Space and Missile Systems Center/Development Planning Directorate). The AeroCube-4 CubeSats represent a constellation of of 3 CubeSats operated by The Aerospace Corporation

Mission details:

• On Sep 13, 2012 United Launch Alliance flew a Lockheed Martin Atlas V 401, serial AV-033, from Vandenberg Air Force Base. The main payload is thought to be a pair of Navy signals intelligence satellites deployed in a 1010 x 1200 km x 63.4 deg orbit after the second Centaur burn.
• The Centaur then made two further burns to 470 x 780 km x 64.7 deg. The Centaur second stage carries the OUTSat secondary payload which ejected 11 small 'cubesats,' for a mixture of US military and university customers.
• The OUTSat structure is the NPSCUl launcher developed by the US Naval Postgraduate School. It contains 8 P-POD cubesat deployers which ejected the individual cubesats, a mixture of 1U (0.1m cube), 2U (0.1 x 0.1 x 0.2m box) and 3U (0.1 x 0.1 x 0.3m box) payloads, as follows:
  

    Pod 1 3U SMDC-ONE 1.2     (US Army Space and Missile Defence Command, Huntsville, Alabama)
                               Comms
    Pod 3 3U Aeneas           (U. Southern California, Los Angeles and Dept. of Homeland Security)
                               Cargo container tracking

                               Radiation belt electrons and protons
    Pod 5 1U CP5              (Cal Poly. State U., San Luis Obispo)
                               Solar sail deorbit technology
          2U CXBN             (Morehead State U., Morehead, Kentucky)
                               Cosmic Hard X-ray background
    Pod 6 3U CINEMA 1         (U Cal. Berkeley)
                               Magentospheric studies
    Pod 7 3U Re               (Lawrence Livermore Natl. Lab, California)
                               Space debris tracking
    Pod 8 3U SMDC-ONE 1.1     (US Army Space and Missile Defence Command, Huntsville, Alabama)
                               Comms
    Pod 2 1U Aerocube 4       (Aerospace Corp., El Segundo, California)
          1U Aerocube 4A      (Aerospace Corp., El Segundo, California)
          1U Aerocube 4B      (Aerospace Corp., El Segundo, California)
  

  
  
• The payloads were ejected in the order Pod 1,3,4,5,6,7,8,2. The OUTSat remained attached to the Centaur.
