With a recent air-launched test vehicle flight that came close to hypersonic speed, research company Draper has accelerated the potential for its flight technology.

Draper, a Cambridge, Massachusetts-based nonprofit, provided the crucial guidance, navigation, and control flight software for the flight. That guidance system was built on the same Draper technology that NASA has used in its Apollo mission, the international space station and space shuttle programs.

“In a broad sense, Draper has been working hypersonic since Apollo,” Rick Loffi, space systems program manager and lead executive for Draper’s Houston campus, tells InnovationMap.

The navigation software controlled the first powered test flight of an air-launched vehicle that approached the hypersonic threshold of Mach 5, or 3,800 miles per hour, or five times the speed of sound.

Stratolaunch successfully completed the flight of its TA-1 Talon test vehicle in the Mojave Desert in March. The California-based company designs and launches aerospace vehicles and technologies, providing access to a reusable hypersonic testing platform, according to its website. The historic test flight landed in the Pacific Ocean, and achieved successful ignition, acceleration and sustained altitude climb.

“The Draper software is really what’s stabilizing the vehicle during flight…and controlling it as it gets up into altitude and speed,” Brandon Jalbert, space systems program manager for Draper and team lead for Stratolaunch, says “so it’s not doing loop-de-loops, or getting unstable…blowing up in the atmosphere.”

Draper uses model-based design and algorithms in its software, and for the boost phase of the Talon test, Draper developed a novel algorithm, which built upon its previous work for NASA, Jalbert says.

Aerospace manufacturing companies like Boom and Hermeus stand poised to pick up where the Concorde left off, and are racing to implement and execute on accessible hypersonic and supersonic commercial technology.

The Concorde aircraft made supersonic, four-hour transoceanic flights a reality, but only for the very wealthy, and shut down in 2003.

Draper is not involved in any of those ventures to bring accessible supersonic flight back to the skies. Its primary focus with hypersonic will remain with deterrence and testing platforms, Jalbert says.

But the company’s technology “has applications everywhere from military to commercial activity,“ he says.

“Our focus is to solve complex challenges of national importance,” he says, “whether that’s…helping our commercial partners, or working on civil or military applications. That’s where we see ourselves being of value to the industry.”

With the harsh conditions involved in hypersonic flight, advancing the technology has its challenges.

“You’ve got to have proper hardware and electronics and sensors that can operate within those conditions,” Jalbert says.

Draper originated in 1932 when engineer Charles Stark Draper founded what eventually became the Instrumentation Lab at MIT.

His work on inertial navigation theory paved the way for the use of the autopilot in today’s commercial jets. The lab was divested by MIT in the 1970s, and became a nonprofit. Draper has long been a government contractor and has worked on many military projects, dating to WWII.

Draper in 2023 secured the $2.2 billion renewal of a long-standing contract with the U.S. Navy to provide the guidance system for the submarine-launched Trident II D-5 missile.

The U.S. government has shown a growing interest in the development of hypersonic weapons systems, as Russia and China have developed advanced capabilities.

The Pentagon’s budget request for hypersonic research for fiscal year 2025 was $6.9 billion, up from $4.7 billion for 2023, according to a recent U.S. Naval Institute report.

“There’s a big shift, in deterrence, as well as offensive, on hypersonic,” Jalbert says.

However, the Defense Department has not yet acquired hypersonic weapons, according to the report, but is developing prototypes and testing.

Draper has a long, celebrated history with NASA, and its Houston office is housed at Johnson Space Center. Draper's presence in Houston dates back to the 1960s, Loffi says.

From the Apollo missions to the space station and now the Artemis program, which aims to land the first person of color and the first woman on the moon by 2026 on its Orion spacecraft, Draper has partnered with NASA every step of the way, providing its navigation system for space flight.

“Right now, our biggest customer within NASA is the Orion program,” Loffi says, with approximately 15 of the 20-person Houston office working on the project, in collaboration with the company’s Cambridge colleagues.

The company is also working with NASA on lunar landing technology and sub-orbital experiments, as well as the propulsion element and Gateway space station for Artemis.

Amazon founder Jeff Bezos’s aerospace manufacturing company Blue Origin is also partnering with Draper to develop the Artemis human landing system.

Neither Loffi nor Jalbert aspired to go into outer space themselves, but rather to provide solutions to make that possible. Human spaceflight has been a lifelong passion for Loffi.

While he had lots of job opportunities after graduating from Purdue University with a degree in electrical engineering, Loffi chose NASA.

“I wasn’t that person who grew up dreaming of becoming an astronaut,” Loffi says. “I was old enough to see the Apollo 11 moon landing, and it did inspire me.”

His work at NASA began after the space shuttle Challenger explosion, in 1986. He was part of the agency’s effort to return to space flight, and worked on space station development, before joining Draper in 2011.

Jalbert, a graduate of Northeastern University, says his early work at Draper “lit the fires for my interest in space.”

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
