SpaceX Launches U.S.A.F.'s X-37B As IrmA Bears Down
In spite of the Category 5 Hurricane Irma raging in the Atlantic Ocean at the time of this writing, SpaceX successfully launched the U.S. Air Force’s X-37B, the Orbital Test Vehicle 5 (OTV-5) payload from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida on Thursday, September 7 at 10:00 a.m. EDT.
Following stage separation, Falcon 9’s first stage successfully landed at SpaceX’s Landing Zone 1 (LZ-1) at Cape Canaveral Air Force Station, Florida.
This Air Force mission is the fifth Boeing X-37B Orbital Test Vehicle launch. The X-37B is the Air Forces’ unmanned and reusable space plane that resembles a small space shuttle, which will conduct orbital experiments.
Currently the only rocket fully designed and developed in the 21st century, Falcon 9 delivers payloads to space aboard the Dragon spacecraft or inside a composite fairing.
Safety and mission success were critical in the design of the Falcon 9 rocket. With a minimal number of separation events and nine first-stage Merlin engines, the SpaceX Falcon 9 rocket is designed so that even if two of the engines shut down, the rocket can still operate.
In 2012, SpaceX became the first commercial company to rendezvous with the International Space Station. Although these flights have not transported crew, SpaceX continues to work toward their goal of one day carrying astronauts to space in Crew Dragon’s pressurized capsule using the Falcon 9.
Lockheed Martin's GPS III SV02 Accomplishes Acoustic Assay
The launch is the most strenuous part of a satellite’s life — to survive the extreme sound wave pressure and pounding vibrations generated by more than 700,000 lbs. of thundering rocket thrust, spacecraft need a solid, reliable design if they hope to arrive operational on orbit.
On July 13, Lockheed Martin’s (NYSE: LMT) second, fully-assembled GPS III space vehicle (SV) completed a realistic simulation of its future launch experience and passed this critical acoustic environmental test with flying colors.
During acoustic testing, the GPS III SV02 satellite was continuously blasted with deafening sound reaching 140 decibels in a specialized test chamber equipped with high-powered horns. For comparison, that is about as loud as an aircraft carrier deck and human hearing starts to be damaged back at about 85 decibels. The test uses sound loud enough to literally shake loose anything not properly attached.
The GPS III SV02 satellite is part of the U.S. Air Force’s next-generation of GPS satellites that will bring critical new capabilities to the warfighter.
GPS III will have three times better accuracy and up to eight times improved anti-jamming capabilities. Spacecraft life will extend to 15 years, 25 percent longer than the newest GPS satellites on-orbit today.
GPS III’s new L1C civil signal also will make it the first GPS satellite to be interoperable with other international global navigation satellite systems.
GPS III SV02 is Lockheed Martin’s second GPS III satellite to successfully complete acoustic testing.
The company’s first satellite, GPS III SV01 — which is in storage awaiting its expected 2018 launch — completed acoustic testing in 2015.
The GPS III SV02 satellite is now being prepared for Thermal Vacuum (TVAC) testing this fall, where it will be subjected to extreme cold and heat in zero atmosphere, simulating its on-orbit life.
The satellite is expected to be delivered complete to the Air Force in early 2018. GPS III SV02 is the second of 10 GPS III satellites Lockheed Martin is contracted for and is assembling in full production at the company’s GPS III Processing Facility near Denver. The $128 million, state-of-the-art manufacturing factory includes a specialized cleanroom and testing chambers designed to streamline satellite production.
Lockheed Martin’s unique GPS III satellite design includes a flexible, modular architecture that allows for the insertion of new technology as it becomes available in the future or if the Air Force’s mission needs change. Satellites based on this design are already proven compatible with both the Air Force’s next generation Operational Control System (OCX) and the existing GPS constellation.
The GPS III team is led by the Global Positioning Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Air Force Space Command’s 2nd Space Operations Squadron (2SOPS), based at Schriever Air Force Base, Colorado, manages and operates the GPS constellation for both civil and military users.
Mark Stewart, Lockheed Martin’s VP for Navigation Systems, commented that with this launch-simulation test, sophisticated, advanced satellite technology and electronics endured tremendous forces and then worked flawlessly afterward. Passing this test with GPS III SV02 further validates the robustness of the Lockheed Martin GPS III design.
