T+plus 35 minutes. According to the normal launch plan, shortly after the rocket rocket enters this temporary orbit, it maneuvers itself into the proper orientation for the coast. At T+plus 44 minutes, 30 seconds, the second stage will perform another maneuver get into the correct position for the next engine firing.

T+plus 40 minutes. The Air Force says the launch is proceeding per the plan. The rocket is coasting until the second stage restarts its engine at T+plus 52 minutes, 52 seconds for a brief 21-second firing to put the vehicle into a near-circular sun-synchronous orbit above Earth. Deployment of STSS-ATRR from the launch vehicle is expected to be confirmed nearly 58 minutes after liftoff.

T+plus 50 minutes. The next firing by the Delta rocket's second stage is coming up in just under three minutes. The Hartebeesthoek tracking station in South Africa should acquire the rocket's signal momentarily as it flies northbound.

T+plus 45 minutes. The official liftoff time was 1:24:25.757 p.m. PDT.

T+plus 53 minutes, 30 seconds. The second stage engine has performed its approximate 21-second firing to propel spacecraft payload into polar orbit.

T+plus 57 minutes. The deployment of STSS-ATRR from the Delta second stage is a two-step process. The payload attach fitting's separation bolts will be released at T+plus 57 minutes, 30 seconds. A set of secondary latches then disengage at T+plus 58 minutes, allowing the satellite to physically separate from the rocket.

The second stage then performs a retro maneuver to back away from the spacecraft. That will be followed by a firing of the stage's engine about 18 minutes later to move the rocket farther from the spacecraft and then another burn about 45 minutes from now to deplete the remaining fuel supply as a safety measure.

T+plus 58 minutes, 18 seconds. SPACECRAFT SEPARATION! The Space Tracking and Surveillance System has been released from the Delta 2 rocket's second stage, completing today's launch!

This quasi-classified spacecraft is a research and development testbed for the U.S. Missile Defense Agency. The $400 million mission, known as STSS-ATRR for short, is designed to be a stepping stone that will ease the riskiness of new technologies for the MDA's Ballistic Missile Defense System.

Missile Defense Agency Space Tracking and Surveillance System Advanced Technology Risk Reduction Satellite transfers to Air Force Space Command

Operational and administrative control of the Space Tracking and Surveillance System Advanced Technology Risk Reduction (STSS ATRR) satellite has been transferred to Air Force Space Command (AFSPC) effective 31 January 2011. In addition to successfully demonstrating required on orbit system performance parameters for a prototype sensor technology, STSS ATRR has been conducting Space Situational Awareness (SSA) and related operations on an as-capable basis. As an AFSPC system, STSS ATRR will continue operations supporting the Space Situational Awareness (SSA) mission area.

STSS ATRR was launched 5 May 2009 from Vandenberg Air Force Base. STSS ATRR is a small experimental satellite that served as a pathfinder for prototype sensor technology and future MDA space missions.

Northrop Grumman + Raytheon... Timely Trajectory Tracking

When split seconds count, this system passed its acquisition test...

The Space Tracking and Surveillance System (STSS) demonstration satellites successfully acquired and tracked a short-range, air-launched target (SRALT) July 8th in a test that showed their ability to track dim objects that have extremely short flight timelines. The satellites were built by Northrop Grumman Corporation (NYSE:NOC), prime contractor, and Raytheon Company, sensor payload provider, for the U.S. Missile Defense Agency (MDA). The exercise verified target capabilities and did not involve an intercept attempt.

"Air-launched targets have a wide variety of trajectories. There's nothing predictable about their flights. The STSS demonstrators successfully tracked this target and collected key data about test conditions and the dynamics of air-launched targets that will be valuable for MDA's predictive capability," said Doug Young, vice president of missile defense and missile warning programs for Northrop Grumman's Aerospace Systems sector.

One single-stage, solid-fueled rocket was drop-launched from the rear of a C-17 cargo aircraft by MDA over the Pacific Ocean Test Range near San Nicolas Island off the Central California coast. The SRALT was selected as a target because it closely replicates realistic engagement scenarios. "This was the first time the STSS sensors have been tested against air-launched targets, and they performed flawlessly," said Bill Hart, vice president, Raytheon Space Systems. "Against such short-range targets, split seconds count. That's why a near-immediate reaction system like STSS is so important to our national defense."

Plans call for the STSS satellites to continue on-orbit testing by participating in a series of performance demonstration tests with ground, airborne, resident space objects and ballistic missile targets to reduce the risk of an operational constellation of space-based sensors for missile defense. According to MDA, the additional flight tests will demonstrate the ability to track various targets, providing critical demonstrator performance characterization while progressing towards closing the fire control loop with Ballistic Missile Defense System (BMDS) interceptors using space-based infrared tracking. MDA is operating STSS as an experimental space layer of the BMDS. Using sensors capable of detecting visible and infrared light, the STSS satellite constellation is part of a collection of land-, sea-, air- and space-based BMDS sensors. They are gathering critical engagement conditions and empirical measurement event data, among other missions.
