On Sep 13 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 primary satellite is

USA 238; the secondary satellite has not yet been cataloged and may not

have separated yet). This series of satellites is thought to be the modern

successor to NRL's GRAB/POPPY/PARCAE satellites, first launched in 1960.


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.

Of particular interest is CXBN, a Morehead State U. experiment to produce

an all-sky 30-50 keV hard X-ray cosmic diffuse emission map. The two US

Army sats in the SMDC-ONE (Operational Nanosatellite Effect) program

are variously numbered 1.1/1.2 and 2.1/2.2 in different sources.


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)


Pod 3 3U Aeneas (U. Southern California, Los Angeles and Dept. of Homeland Security)

Cargo container tracking

Pod 4 3U CSSWE (U. Colorado, Boulder) Colorado Student Space Weather Expt.

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)


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. I believe

the OUTSat remained attached to the Centaur; whether you count it as an

attached secondary payload or a non-payload piece of hardware is a

matter of taste, but I'll count it as a payload.


Since their first flight in 2003, 102 Cubesats have been launched: 2

suborbital, 19 launch failures (4 exoatmospheric), and 81 orbital. Of

these, 60 are still in orbit. This includes two attached pairs,

M-Cubed/E1PU2 and STARS-1, and five cubesats currently aboard the Kibo module

which should be deployed later this month.
