During the qualification effort, NTS working with directly with Boeing Company—and established one leadership team to work with all NTS laboratories. As a result of this effort, NTS was nominated by both Boeing Company and Lockheed Martin for the prestigious space award. According to Lockheed Martin, “The qualification and testing of hardware for human-rated space flight systems is unique and extensive; and is a critical step in delivering to NASA the safest and most reliable systems for human space exploration. At the at the Washington IAF conference in Washington D.C, NTS was awarded the NASA FSA award. It was the first time that this award has ever been given to an independent test laboratory.

Astronautics and Propulsion Testing

Aerospace propulsion testing involves programs that measure the effectiveness of an aircraft or spacecraft’s engine and thrust systems. We utilize space simulation testing and other programs to establish an engine’s reliability and compliance. Propulsion testing becomes critical for successful spacecraft operations, both crewed and uncrewed.

Spacecraft require functioning propulsion systems to achieve their intended purpose. Due to the differences in pressure, humidity and temperature in space, space propulsion testing requires simulating these conditions. At NTS, we have access to a state-of-the-art rocket testing facility that enables us to replicate the environmental demands of space.

During the initial development phases, we use static testing to search for faults and defects in a spacecraft. Static tests allow us to focus on engine performance without movement as a confounding factor. We then move on to programs conducted within our thrust measuring system (TMS). The TMS includes water-cooled ducts that can handle up to 50,000 pounds of thrust that reduce sound levels during testing. Our team can conduct additional testing on engine components in pressure vessels, valves and components that simulate extreme conditions.

  • Exhaust duct rocket and thrust stand testing with up to 50,000-lbf of thrust
  • Large run tanks and pressure vessels
  • Pressurization flow systems and gas storage
  • Propellant-run tanks and flow systems
  • General subsystem and component assembly
  • Vaporization systems and cryogenic fluid storage
  • Hot water and steam flow test systems
  • Quiet technology test facility

Satellite Systems and Large-Scale Programs

As with spacecraft, satellites require extensive space simulation testing before project execution. Select NTS locations serve as national satellite test facilities that support our clients’ satellites throughout their life cycles. Satellite testing from NTS involves careful inspection and precise program execution for all satellite components. These include transmission equipment, antennas, fuel cells, solar panels and batteries.

Our experience with nearly every major U.S. space program has established us as a leader in space and satellite hardware testing. Industry leaders such as SpaceX, Blue Origin, Lockheed Martin and Boeing rely on us for program assistance. We provide complete support in the following areas of space development:

  • Testing and systems evaluations
  • Research and development

We offer additional services for a wide range of components, systems and devices used in large-scale programs. The versatility of our services allows our clients to request a solution that accounts for multiple project aspects.


Advancements in Satellite Testing

With advances in technology, the government and corporations alike rely on satellites. The U.S. military counts on satellites for navigation, communications and intelligence gathering. Meanwhile, companies use them for telecommunications and radio applications vital to our society. Satellite manufacturers must create a reliable product that supports these critical functions. Testing ensures that the final product will achieve its intended purpose while in Earth’s orbit.

During satellite testing, the professional conducting the test programs must consider every contingency. Once a satellite is in orbit, it must work at peak performance it will stay out of reach of repair. Since large-scale programs like satellites involve large amounts of money and effort, the manufacturer has much to lose from product failure.

Qualified organizations such as NTS can conduct testing programs that leave no component unchecked. We have decades of experience working with sensitive satellite parts designed for critical programs. Our team understands how to simulate extreme space conditions while leaving equipment intact. At NTS, we know that a satellite launch has no room for error.


Space Simulation Testing

Once spacecraft and satellites enter orbit, they must withstand the harsh conditions experienced in space. In space simulation testing, NTS specialists use advanced chambers to imitate space’s temperatures, pressure and humidity. With results spanning to the beginning of U.S. manned space exploration, we understand how to prepare equipment for space travel.

Hypersonic Testing

Hypersonic flight, which involves projectiles racing at speeds above Mach 5, is a hot topic in defense and aerospace circles. In fact, the development of a hypersonic defense weapon system is critical to national security. At NTS, engineers are creating different tests to simulate hypersonic flight, including aerodynamic heating—a simulation that involves burner temperatures up to 4,000 °F.

Precision Cleaning Services

Debris, corrosion and contaminants can lead to outgassing and product failure, but the NTS team can assist. The precision cleaning services available from NTS address issues that impact your components’ performance. Our extensive portfolio of aerospace cleaning capabilities features services such as:

  • Particle and residue analyses
  • Commercial oxygen cleaning
  • Leak testing
  • Ultra-high-purity processing

Your project may require multiple precision cleaning methods to remove all contaminants. Our team inspects cleaned components on the basis of visual cleanliness, particle count and presence of non-volatile residue. During these processes, they also evaluate parts for their compatibility with spacecraft systems. NTS cleaning specialists also utilize multiple drying methods to prevent outgassing and residual moisture.

Our clients may request specialty packaging designed to mitigate risk during the storage and transportation of sensitive components. We can utilize three or more layers of protection as we seal and package the final result of the cleaning process. Most of our standard procedures involve up to three layers, and we can accommodate projects that require more barriers.

Organizations in need of cleanroom facilities to conduct their own testing may rent our Class 10,000 cleanroom or Class 100 flow benches. We offer these facility rentals in half- or full-day increments with the option to include support from NTS technicians. You may also request functionality testing after the completion of cleanliness verification.

MIL-STD-810 testing evaluates a product’s life cycle in the face of rugged environmental conditions. By replicating the effects of the product’s intended environment, the test allows for the collection of in-depth data. During MIL-STD-810 testing, the manufacturer determines the product’s reliability and compliance. Clients may choose from 28 MIL-STD-810 testing methods meant to replicate a range of conditions.

MIL-STD-202 testing examines a piece of equipment’s electrical parts that weigh under 300 pounds. It outlines the test protocols used for all components and products featuring printed circuit boards. The test methods featured in MIL-STD-202 involve environmental tests, physical characteristic tests and electrical characteristic tests.

RTCA DO-160 encompasses the procedures required for aircraft. These tests evaluate the performance of airborne equipment used in aerospace operations.
