CAPE CANAVERAL, Fla. --- A United Launch Alliance (ULA) Atlas V 501 rocket carrying the USSF-7 mission for the U.S. Space Force lifted off on May 17, 9:14 a.m. EDT, from Space Launch Complex-41. This marks the 84th successful launch of an Atlas V rocket, 139th launch for ULA, the second launch for the U.S. Space Force and the sixth flight of the X-37B Orbital Test Vehicle (OTV-6).

“The success of this mission resulted from collaboration with our customer while working through challenging, and ever changing, health and safety conditions,” said Gary Wentz, ULA vice president of Government and Commercial Programs. “We were honored to partner with the U.S. Space Force to dedicate this mission to first responders, front-line workers, and those affected by COVID-19. It is truly a unique time in our history and I want to thank the entire team for their continued dedication and focus on mission success.”

Along with OTV-6, this mission deployed FalconSat-8, a small satellite developed by the U.S. Air Force Academy and sponsored by the Air Force Research Laboratory (AFRL) to conduct experiments on orbit. The mission also carried two NASA experiments, including a material sample plate to determine the results of radiation and other space effects on various materials, and an experiment which will assess space effects on seeds used to grow food. Another experiment sponsored by the Naval Research Laboratory will examine the ability to transform solar power into radio frequency microwave energy which could be transmitted to the ground.

This mission launched aboard an Atlas V 501 configuration rocket that included a 5-meter-diameter payload fairing. The Atlas booster was powered by the RD AMROSS RD-180 engine, and the Centaur upper stage was powered by the Aerojet Rocketdyne RL10C-1 engine.

ULA’s next launch is NASA’s Mars 2020 mission carrying the Perseverance rover on an Atlas V rocket. The launch is scheduled for July 17 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla.

To date ULA has a track record of 100% mission success with 139 successful launches.


With more than a century of combined heritage, ULA is the world’s most experienced and reliable launch service provider. ULA has successfully launched more than 135 missions to orbit that provide Earth observation capabilities, enable global communications, unlock the mysteries of our solar system, and support life-saving technology.

Boeing-Built X-37B Launches in Second Mission for U.S. Space Force

CAPE CANAVERAL, Fla --- The Boeing built X-37B autonomous spaceplane today launched on top of a uniquely configured United Launch Alliance Atlas V rocket.

Boeing is the prime contractor for the X-37B spaceplane and facilitates the integration of all experiments into the vehicle ensuring they receive the correct power, thermal and data services required. Boeing also works to identify future reusable platform experiment opportunities on each mission.

The X-37B’s sixth mission is the first to use a service module with additional payload capability to support a variety of experiments for multiple government partners. The mission will deploy FalconSAT-8, a small satellite developed by the U.S. Air Force Academy and sponsored by the Air Force Research Laboratory, to conduct experiments on orbit.

Further, two NASA experiments will study the impact of radiation and other space effects on certain materials and seeds used to grow food. Another experiment by the Naval Research Laboratory will transform solar power into radio frequency microwave energy which could then be transmitted to the ground. In addition, the mission will test reusable space vehicle technologies.

The X-37B first launched in April 2010. Originally designed for missions of 270 days duration, the X-37B has set endurance records during each of its five previous flights. Most recently, X-37B spent 780 days on orbit before returning to Earth in October 2019.

“The X-37B has shifted the paradigm and redefined efficiency in space development, said Jim Chilton, Boeing Space and Launch senior vice president. “The rapid technology advancements enabled by the program will benefit the entire space community and influence the next generation of spacecraft design.”

The X-37B program is a partnership between the Department of the Air Force Rapid Capabilities Office and the United States Space Force. Boeing program management, engineering, test and mission support functions for the Orbital Test Vehicle (OTV) program are conducted at Boeing sites in Southern California and Florida.
