STP has actually been in existence for 50 years as of 2019, with several thousand launches it has been responsible for. For example, the initial experiments that led to the modern <a href="Global_Positioning_System" title="Global Positioning System">Global Positioning System</a> (GPS) satellite constellation were STP-launched projects.

During August 2001, STP conducted two successful activities using the <a href="Space_Shuttle" title="Space Shuttle">Space Shuttle</a> and ISS. <a href="STS-105" title="STS-105">STS-105</a> delivered and successfully deployed the <a href="Materials_International_Space_Station_Experiment" title="Materials International Space Station Experiment">Materials International Space Station Experiment</a> (MISSE) externally on the ISS. MISSE was a passive materials exposure experiment, was the first external experiment on ISS. In addition, STS-105 retrieved and returned MACE II (Middeck Active Control Experiment II) from the ISS. MACE II was the first internal experiment on ISS and was operated for nearly a year.<a href="#cite_note-6">[6]</a>

On 30 September 2001, STP and <a href="NASA" title="NASA">NASA</a> launched the Kodiak Star mission on an <a href="Athena_I" title="Athena I">Athena I</a> <a href="Launch_vehicle" title="Launch vehicle">launch vehicle</a>. This was the first orbital launch out of <a href="Kodiak_Island" title="Kodiak Island">Kodiak Island</a>, <a href="Alaska" title="Alaska">Alaska</a>. In addition to NASA's <a href="STARSHINE" class="mw-redirect" title="STARSHINE">Starshine III</a> spacecraft, this mission included three small DoD spacecraft which tested a variety of new space technologies.<a href="#cite_note-7">[7]</a>

STP and the <a href="Air_Force_Research_Laboratory" title="Air Force Research Laboratory">Air Force Research Laboratory</a>'s (AFRL) Space Vehicles Directorate developed a secondary payload adapter ring for the <a href="National_Security_Space_Launch" title="National Security Space Launch">Evolved Expendable Launch Vehicle</a> (EELV), which can host up to six 180 kg (400 lb) <a href="Small_satellite" title="Small satellite">microsatellites</a>. STP also worked closely with NASA and the <a href="United_States_Navy" title="United States Navy">United States Navy</a> on the Geosynchronous Imaging Fourier Transform Spectrometer / Indian Ocean Meteorology and Oceanography Imager project.

In December 2001, <a href="STS-108" title="STS-108">STS-108</a> hosted the Shuttle Ionospheric Modification with Pulsed Localized Exhaust (SIMPLEX) experiment. SIMPLEX observed ionospheric disturbances created by the Space Shuttle engine burns via ground radar sites and supported plume technology, plume signature, and space weather modeling.

SIMPLEX flew again on <a href="STS-110" title="STS-110">STS-110</a> in April 2002. STP also worked to obtain a 1-year radio frequency license extension for the Picosat experiment launched on the Kodiak Star mission, in September 2001.

On 6 January 2003, STP and the <a href="Naval_Research_Laboratory" class="mw-redirect" title="Naval Research Laboratory">Naval Research Laboratory</a> (NRL) launched the <a href="Coriolis_(satellite)" title="Coriolis (satellite)">Coriolis</a> satellite, a risk-reduction effort for <a href="NPOESS" title="NPOESS">NPOESS</a>, aboard a <a href="Titan_23G" title="Titan 23G">Titan II</a> launch vehicle.<a href="#cite_note-8">[8]</a>

On 9 March 2007, six satellites were launched into <a href="Low_Earth_Orbit" class="mw-redirect" title="Low Earth Orbit">low Earth Orbit</a> (LEO) on a shared <a href="Atlas_V" title="Atlas V">Atlas V</a> launch vehicle on the STP-1 mission.<a href="#cite_note-GSP-9">[9]</a> The satellites were:

<ul><li><a href="Orbital_Express" title="Orbital Express">Orbital Express</a>: ASTRO and NextSat, (<a href="DARPA" title="DARPA">DARPA</a>)</li>

<li><a href="MidSTAR-1" title="MidSTAR-1">MidSTAR-1</a>, (<a href="United_States_Naval_Academy" title="United States Naval Academy">United States Naval Academy</a>)</li>

<li><a href="CFESat" title="CFESat">CFESat</a>, (<a href="Los_Alamos_National_Laboratory" title="Los Alamos National Laboratory">Los Alamos National Laboratory</a>)</li></ul>

The satellites shared the launcher through use of an <a href="EELV_Secondary_Payload_Adapter" title="EELV Secondary Payload Adapter">Evolved Expendable Launch Vehicle Secondary Payload Adapter</a> (<a href="EELV_Secondary_Payload_Adapter" title="EELV Secondary Payload Adapter">ESPA</a>).<a href="#cite_note-10">[10]</a> <a href="United_Launch_Alliance" title="United Launch Alliance">United Launch Alliance</a> provided a video feed of the launch.<a href="#cite_note-11">[11]</a>

The <a href="C/NOFS" title="C/NOFS">C/NOFS</a> (Communications/Navigation Outage Forecasting System) satellite, which was launched on 16 April 2008, was operated by the Space Test Program.

The third <a href="Minotaur_IV" title="Minotaur IV">Minotaur IV</a>, known as <a href="STP-S26" class="mw-redirect" title="STP-S26">STP-S26</a>, was successfully launched in November 2010. This was the 26th small launch vehicle mission in STP's 40-year history of flying DoD space experiments,<a href="#cite_note-spacenews-12">[12]</a> STP-S26 launched at 01:45 <a href="Coordinated_Universal_Time" title="Coordinated Universal Time">UTC</a> on 20 November 2010 from the <a href="Pacific_Spaceport_Complex_%E2%80%93_Alaska" title="Pacific Spaceport Complex – Alaska">Kodiak Launch Complex</a>. The launch facility contractor was <a href="Pacific_Spaceport_Complex_%E2%80%93_Alaska" title="Pacific Spaceport Complex – Alaska">Alaska Aerospace Corporation</a> (AAC). The payloads were released in a 650 km (400 mi) orbit, before the <a href="Hydrazine" title="Hydrazine">Hydrazine</a> Auxiliary Propulsion System (HAPS) upper stage, by <a href="Orbital_Sciences_Corporation" title="Orbital Sciences Corporation">Orbital Sciences Corporation</a>, was demonstrated by deploying two ballast payloads into a 1,200 km (750 mi) orbit. The payload included the STPSat-2 spacecraft.<a href="#cite_note-STPSat-2-and-3-13">[13]</a> STPSat-2 had 3 three experimental payloads:

SPEX (Space Phenomenology Experiment) consisting of two payloads to evaluate sensor compatibility for the space environment, and

ODTML (Ocean Data Telemetry MicroSatLink) a two-way data relay from terrestrial (ocean or land) sensors to users.<a href="#cite_note-14">[14]</a>

STPSat 3 is a copy of the STPSat-2 satellite, adapted to carry six experiments, including a module designed to host various space situational awareness sensors and a pair of space environment sensors. STPSat 3 launched on 19 November 2013, on the ORS-3 <a href="Minotaur_1" class="mw-redirect" title="Minotaur 1">Minotaur 1</a> launch, along with 28 CubeSats.<a href="#cite_note-ORS-3-15">[15]</a> STPSat-3 carries five payloads, including "Integrated Miniaturized Electrostatic Analyzer Reflight (iMESA-R), Joint Component Research (J-CORE), Strip Sensor Unit (SSU), Small Wind and Temperature Spectrometer (SWATS), and TSI Calibration Transfer Experiment (TCTE)". It also carries a de-orbit module.<a href="#cite_note-STPSat-2-and-3-13">[13]</a>

As announced on 14 October 2014, the <a href="United_States_Department_of_Defense" title="United States Department of Defense">United States Department of Defense</a> awarded <a href="Sierra_Nevada_Corporation" title="Sierra Nevada Corporation">Sierra Nevada Corporation</a>'s Space Systems (previously known as <a href="SpaceDev" title="SpaceDev">SpaceDev</a>) with a contract to develop and build a next-generation science and technology demonstration satellite, known as STPSat-5, for their Space Test Program.<a href="#cite_note-16">[16]</a>

The STP-2 (DoD Space Test Program) payload launched aboard a <a href="SpaceX" title="SpaceX">SpaceX</a> <a href="Falcon_Heavy" title="Falcon Heavy">Falcon Heavy</a> on 25 June 2019.<a href="#cite_note-17">[17]</a>

Included was <a href="COSMIC-2" title="COSMIC-2">COSMIC-2</a>, a cluster of six satellites, with a mass of 277.8 kg (612 lb) each.<a href="#cite_note-fbo-18">[18]</a> The primary role of the COSMIC-2 <a href="Satellite_constellation" title="Satellite constellation">satellite constellation</a> is to provide <a href="Radio_occultation" title="Radio occultation">radio occultation</a> data with an average latency of 45 minutes. The six satellites were placed on an orbit with an inclination of 24° to 28.5° with plans for them to move eventually to six separate orbital planes with 60° separation between them.<a href="#cite_note-19">[19]</a> The payload stack was integrated using an <a href="ESPA_ring" class="mw-redirect" title="ESPA ring">ESPA ring</a>.
