A United Launch Alliance (ULA) Atlas V rocket launched the AEHF-6 mission on Thursday, March 26, 2020 at 8:18 PM (UTC). Issues were encountered with its kick motor, and it was forced to use its reaction and Hall thrusters to reach its intended orbit. Support is provided for on-orbit anomaly resolution and investigation, flight and payload software sustainment following the completion of on-orbit test, Networked AEHF System Tested tool sustainment, mission control familiarization, and development test. Fiscal year 2018 and 2019 research, development, test and evaluation funds in the amount of $3,959,991 are being obligated at the time of award.Lockheed Martin Space Systems Corporation, Sunnyvale, California, is being awarded a $312.2 million cost-plus-incentive-fee contract modification for engineering support for the Advanced Extremely High Frequency (AEHF) satellite program from December 1, 2011 to December 31, 2014. The TDO-2 satellite was built for the Air Force Research Laboratory by the Georgia Institute of Technology, and will serve as a target for laser ranging and calibration tests.With TDO-2 deployed, AV-086’s mission entered an extended coast phase prior to the third Centaur burn and deployment of AEHF-6. The contract modification is to make changes to the AEHF Mission Planning Element software to provide capability improvements. This means they need to burn less fuel to reach geostationary orbit, while also leaving the rocket’s upper stage in a higher disposal orbit where it is less likely to collide with other objects.Atlas V was developed by Lockheed Martin under the A two-stage rocket, Atlas V consists of a Common Core Booster (CCB) with a Centaur upper stage. United Launch Alliance’s Atlas V rocket carried out its first mission for the United States Space Force Thursday, deploying the final Advanced Extremely High Frequency (AEHF) satellite to provide secure communications for the US military and its allies. The container carrying the AEHF-6 satellite is unloaded from a C-5M aircraft for transportation to the Astrotech Space Operations processing facility in Titusville, Florida, for final preparation for the satellite’s March launch. Although earlier AEHF satellites were launched using the less powerful 531 configuration, the switch to the 551 from the fourth launch onwards has allowed the satellites to be deployed into a transfer orbit with a higher perigee. After clearing the launch pad, Atlas began a series of pitch, roll and yaw maneuvers to establish an easterly trajectory out over the Atlantic Ocean.It took about 34 seconds for Atlas to reach Mach 1, the speed of sound. Work will be performed in Marlborough, Massachusetts, and is expected to be completed by August 30, 2019. The majority of the work will be performed at Raytheon's facilities in Marlborough, Massachusetts; and Largo, Florida, and is expected to be completed by August 2023. Subsequent AEHF satellites were launched in May 2012, September 2013, October 2018 and August 2019.The AEHF spacecraft are numbered under the “USA” series, used to designate most US military satellites. The official end of mission is expected to be at six hours, thirty-eight minutes and 56.9 seconds elapsed time.Thursday’s launch was the second of the year for United Launch Alliance and its Atlas V rocket, We use cookies to ensure that we give you the best experience on our website. Liftoff from the Cape Canaveral Air Force Station ahead of a long mission to deployment.The AEHF-6 satellite carried into space by Thursday’s launch will complete a constellation of satellites at the core of the US military communications. Space and Missile Systems Center, Los Angeles Air Force Base, California, is the contracting activity.Raytheon Co., Marlborough, Massachusetts, has been awarded a $10,722,437, cost-plus-fixed-fee contract for the Force Element Terminal Risk Reduction effort. Space Operations Command Takes Over AEHF-5 Satellite It was first used in January 2006 to boost the New Horizons probe on its way to Pluto, and next in August 2011 with the Juno mission bound for Jupiter. From the ULA AEHF-5 mission overview giving details about the Atlas V and its Centaur upper stage: Centaur The Centaur second stage is 10 ft. in diameter and 41.5 ft. in length. Power comes from two deployable solar arrays, each consisting of five panels.The propulsion systems aboard each satellite include a BT-4 liquid apogee motor built by Japan’s IHI Corporation, which is used for initial orbit-raising operations. The award is the result of a sole-source acquisition.Lockheed Martin Space, Sunnyvale, California, has been awarded a $15,915,000 modification (P00770) to previously awarded contract F04701-02-C-0002 for Advanced Extremely High Frequency (AEHF).
