STP-S26 is a multi-payload mission executed by the United States Department of Defense (DoD) Space Test Program (STP) at the Space Development and Test Wing (SDTW), Kirtland AFB, NM. The mission was designated STP-S26 to correspond to the 26th small launch vehicle mission in STP's 40-year history of flying DoD space experiments. STP-S26 extends previous standard interface development efforts, implementing a number of capabilities aimed at enabling responsive access to space for small experimental satellites and payloads.
STP-S26 mission will be flying a Minotaur IV launch vehicle (LV), contracted by Orbital Sciences Corporation. Orbital Sciences Corporation is currently contracted to fly several Minotaur IV LVs, all constructed to specifications of the mission. The key difference with STP-S26 launch vehicle is the Hydrazine Auxiliary Propulsion System (HAPS) which gives it dual-orbit capability. Six payloads will be released at the primary orbit of 650 km (404 mi). The LV will then travel to the secondary orbit of 1,200 km (746 mi) to release final payload.

STP-S26 is flying 16 experiments on six satellites. Four satellites are microsatellites (STPSat-2, FalconSAT-5, FASTRAC, FASTSAT-HSV01) and two are CubeSats (RAX, O/OREOS). STP-S26 will also fly Demonstration Separation System (DSS), which will release ballasts at the secondary orbit as a technology demonstrator. DSS is built by Boeing Corporation. Future missions could utilize this capability to deploy spacecraft into either the primary of secondary orbit.
There is O-F Calendar event created for this launch. And here you can request a reminder for it, that will be sent via e-mail.

Launch Vehicle:

The most recent addition to Orbital's line of space launch vehicles, the Minotaur-4 (a.k.a. OSP-2 Peacekeeper SLV) combines elements of government-furnished decommissioned Peacekeeper missiles with technologies from our proven Pegasus, Taurus and OSP Minotaur boosters. The vehicle consists of three Peacekeeper solid rocket stages, a commercial Orion-38 fourth stage motor and subsystems derived from established space launch boosters. Under a 10-year contract with the U.S. Air Force Space and Missile Systems Center, Orbital will develop and operate the low-cost Minotaur-4 vehicle to launch U.S. government-funded satellites into low-Earth orbit.
The Minotaur-4 incorporates a standard 92-inch fairing from the Taurus booster and supports dedicated or shared launch missions. Capable of boosting payloads more than 1,750 kg into orbit, the vehicle is compatible with multiple U.S. government and commercial launch sites. The Minotaur-4 is designed to provide 18-month mission response including payload integration and launch by Orbital's experienced launch crews.
This version of Minotaur IV launch vehicle includes a Hydrazine Auxiliary Propulsion System (HAPS) 5th stage to take the vehicle to a secondary orbit.

STPSat 2 is an experimental spacecraft for STP. It is the first flight of the Standard Interface Vehicle (STP-SIV).
Two experiments are mounted onto the payload standard interface module of the STP-SIV:
|
- SPEX (Space Phenomenology Experiment) is evaluating sensor compatibility for the space environment.
- ODTML (Ocean Data Telemetry MicroSatLink) provides two way data relay from terrestrial (ocean or land) sensors to users (standalone or on the internet).

FASTRAC (Formation Autonomy Spacecraft with Thrust, Relnav, Attitude and Crosslink) is a nanosatellite pair whose design and integration has been undertaken by students at The University of Texas at Austin. The project is part of a program sponsored by the Air Force Research Laboratory (AFRL) whose goal is to lead the development of affordable space technology. The objective of the FASTRAC mission is to investigate technologies that enable space research using satellite formations. The utilization of satellite formations in space is a pivotal advancement for the future of space exploration and research.
The University of Texas is one of 12 universities in the nation selected to participate in this grant-based competition. In January 2005, UT won the opportunity to have their nanosatellites launched into space.
The purpose of the FASTRAC mission is to investigate enabling technologies crucial for satellite formations, including on-orbit micro-thrust capability, relative navigation, attitude determination, and satellite crosslink communications. This will be achieved by taking on-orbit data from a pair of twin satellites that will separate once in orbit. The data will be gathered through a network of civilian ground stations and evaluated through post-processing of the recombined downlink message.
The FASTRAC nanosatellite mission has three primary technical objectives. On-board the satellite, these include two primary experiments: the microdischarge plasma thruster experiment and the GPS relative navigation experiment. The third technical objective is the construction of a civilian distributed ground station network.

FASTSAT-HSV (Fast Affordable Science and Technology Satellite - Huntsville) is small technological satellite to test out cow-cost technologies for rapidly built small satellite missions.
The satellite will carry six small payloads, including three technology demonstration experiments and three atmospheric research instruments.
|
- Nanosail D - a technology experiment to demonstrate FASTSAT's ability to deploy a nanosatellite into space;
- Threat Detection System;
- Miniature Star Tracker;
- Thermosphere Temperature Imager, designed to measure spacecraft drag and other flight characteristics;
- MINI-ME - a low-energy neutral atom imager that will detect neutral atoms formed in the plasma population of the Earth's outer atmosphere to improve global space weather prediction;
- Plasma and Impedance Spectrum Analyzer - a device that will test a new measurement technique for the type and density of thermal electrons in the ionosphere - which can interfere with radio-based communications and navigation.

RAX (Radio Aurora Explorer) is a student-built nanosatellite for ionospheric research. It is built on a triple CubeSat structure.
The RAX will measure the energy flow in the ionosphere, the highest part of Earth's atmosphere where solar radiation turns regular atoms into charged particles.
RAX is a Ground-to-Space Bistatic Radar Experiment. The RAX satellite will act as a receiver that will pick up signals from a ground radar transmitter. These radar pulses will reflect off disturbances, or space weather phenomena, in the ionosphere.

The O/OREOS (Organics and/or Organisms Exposure to Orbital Stresses) satellite Mission is a NASA Science Mission Directorate (SMD) Astrobiology Small Payloads (ASP) free flying science demonstration satellite based on the GeneSat-1/Pharmasat Spacecraft Bus.
O/OREOS has a modified payload structural section, providing for dual modular payload experimental systems. Modified bus software and new payload experiment control software are also being developed. The general mission scenario involves exposing selected organisms and organic compounds to the space environment, and monitoring or assessing changes to them induced by space exposure.
The mission concept is a 5.2 kg (max) free-flying spacecraft launched as a secondary (or piggyback) payload. The target launch is the USAF STP S26 mission from Kodiak Island on a Minotaur IV expendable launch vehicle (Dec. 2009). The orbit will be a circular low Earth orbit (LEO) of 650 km altitude at 72 degrees inclination, with an orbital period of 97.7 minutes. Satellite attitude dynamics in orbit are controlled by permanent magnets and hysteresis rods that dampen rotational energy. The satellite rotates about its long axis (z-axis) at a rate ranging from 1 to 2 RPM. The satellite also experiences a nutation, or “coning”, rotation about it center of mass at a rate of 4-5 RPM with a cone half-angle of less than 13 degrees. This spacecraft motion results in a microgravity environment that varies, but remains below 100 micro-g.
Radiation dose rate on the spacecraft from the inner Van Allen belts and GCR can be as much as 1.4E3 Rads/day. Of this, GCR is expected to make up about 50 mRad/day. Orbit thermal environment varies over time with orbit plane precession (-2.19 degrees per day) and variation in the sun angle (ecliptic plane) during the year.
There are two experiment payloads that include specimens to be exposed to the space environment. One experiment payload includes two biological specimens, while the other payload includes four types of reaction cells containing organic molecules.
The O/OREOS satellite project will develop a simple deployable drag device to assist the satellite with achieving natural orbit decay in less than 25 years. The device simply increases the surface area of the satellite by extending mylar panels. This results in a surface to mass ratio sufficient to achieve the required deorbit. No propellants are required.

FalconSAT-5, is a microsatellite developed in the Department of Astronautics that will carry United States Air Force Academy (USAFA) Physics Department scientific payloads into space.
The payloads that are currently intended to be flown on FS5 are Ion Source, Wafer-Integrated Spectrometer (WISPERS), Smart Miniaturized ElectroStatic Analyzer (SmartMESA), and Reciever UHF/VHF Signal Strength (RUSS).
- Ion Source is a payload resembling that of the Flight heritage Ion Source from Air Force Research Laboratories (AFRL).
- WISPERS measure ions resulting from ion source to validate USAFA and AFRL/PR plume models.
- SmartMESA detects the temperature and density of ambient ions to validate ionospheric data assimilation models.
- RUSS, receives UHF/VHF Signal Strength meter, and characterizes UHF/VHF signal distortion to improve ionospheric models.
FS5 will have two processors sharing the responsibilities. One will deal with the science payloads that are taking data to characterize the ionosphere. The other will do the computations associated with the sensors and actuators used for satellite attitude determination and control. Interface systems with these components will be designed by cadets.
The FalconSAT-5 Attitude Control and Determination System (ADCS) has an active control method, magnetorquers, and a passive control method, the gravity gradient boom. To determine attitude a magnetometer measures the Earth's magnetic field around the satellite and compares the measurements to a model of the magnetic field, and four sun sensors detect the sun vector. The boom is stowed in a box that has to fit inside of the satellite during the launch. Because FS5 could launch on either a Minotaur or an Atlas, the interface to the rocket must be flat. After launch and orbit insertion the magnetometer and magnetorquers will damp out rotation rates until the satellite is spinning slow enough to deploy the boom. An internal configuration changes the characteristics of the gravity gradient control only slightly from those of FalconSAT-3.
With FS5 serving as the prototype, the technological leap to FalconSAT-4 (FS4), which is a more advanced system, will be already mapped out. FS5 is launching before FS4 because some design constraints on FS4 made FS5 more marketable to finding its way on a launch manifest earlier than FS4.

330 km x 685 km, 9°Launch site:
Alaska Aerospace Corporation Kodiak Launch Complex was the USA’s first commercial spaceport not collocated on a federal range. Located about 44 road miles south of the city of Kodiak at Narrow Cape on Kodiak Island, the spaceport is state-of-the-industry and AAC strives to keep it that way. Vigilance, regularly scheduled maintenance, and periodic upgrades govern day-to-day activity. KLC is situated on 3,717 acres of state owned land, and AAC has authority during launch missions to limit public access to an additional 7,000 acres to assure public safety and security.
KLC is the USA’s only high latitude full service spaceport. It features all indoor, all weather, processing and was designed specifically to provide optimal support for space launches to polar orbit, including circular and highly elliptical Molniya and Tundra orbits. KLC offers unrestricted down range launch azimuths ranging from 110° to 220°, and is the only U.S. facility that can launch high inclination (63.4°) missions without land over-flight and the requirement to resort to energy consuming dog leg flight segments. The spaceport, like all U.S. west coast facilities, sits on the seismically active Pacific Rim, and all structures and components are designed to exceed applicable design criteria for seismically active zones.
