On October 28, Terminal Velocity Aerospace
(TVA) signed a Space Act Agreement with NASA Ames Research Center to collaborate on evaluation, testing, and technology transfer of newly-developed thermal protection system (TPS) materials.
“The Space Act Agreement mechanism offers a great way for companies to partner with NASA,” said Dominic DePasquale, the company’s CEO. “I’m excited that we have an opportunity to collaborate with the premier TPS technologists at NASA to transition this TPS material out of the laboratory for use in real missions that deliver value.”
This new development is a multi-year non reimbursable Space Act Agreement and presents both manufacturability and cost saving advantages for customers of TVA’s Reentry Devices (REDs), which collects data during the fiery conditions of spacecraft reentry
“The chief benefit of the conformal thermal protection systems materials developed at NASA Ames is their manufacturability, especially for small reentry probes like TVA’s REDs. By employing the Ames TPS technology, TVA will be able to produce heat shields at lower cost, and those savings can be passed on to customers,” DePasquale said.

TVA began operations in 2012 and is dedicated to improving reentry safety and furthering the utilization of outer space. The company offers a family of small REDs for data collection and cost-effective small payload return through an ongoing relationship with The Aerospace Corporation, and a research and commercialization partnership with the Georgia Institute of Technology.
With the goal of advancing the understanding of reentry and breakup incidents, TVA is working towards addressing the present lack of high quality data on the subject. Atmospheric breakups are the best method for removing spacecraft from orbit. However, TVA reports that 10-40% of spacecraft mass survives reentry. Such debris usually has a high melting point and poses a danger to the public since the location of its landing is currently unidentifiable in advance.
The first device in this line of products, RED-Data, records data during the reentry of its host vehicle to provide a unique insight into the physics behind atmospheric breakup
. DePasquale describes it thus:
Our RED-Data device provides a first-hand account of what occurs during reentry and breakup. The basketball-sized device rides aboard a host vehicle to collect pressure, temperature, acceleration, and other engineering data during the actual reentry event. This high fidelity reentry data is very useful for scientists and engineers for calibrating prediction models and designing for survivability or intentional demise.
The newly signed Space Act Agreement with NASA Ames provides for arc-jet and other ground testing of the new TPS materials at NASA Ames in preparation for flights on TVA’s REDs. With a line of RED-Data devices and Space Act Agreement with NASA Ames under its belt, the next step for TVA involves utilizing the TPS material developed at Ames in the next generation of RED devices, RED-Data2.
“TVA plans to implement the Ames TPS material for RED-Data2, and the entire family of TVA’s next generation RED devices that accomplish missions such as small payload return, reentry flight testing, and ’black box‘ safety recording for crewed space vehicles,” says DePasquale. “RED-Data2 is closer to the size of a softball as opposed to a basketball. It is also more than 50% lighter, autonomously initiated, and capable of passive in-space operations for several years as opposed to months. These characteristics of RED-Data2 allow for reentry data collection from an extended set of host vehicles including launch vehicle upper stages and small Earth orbiting spacecraft.”
These development brings humanity one step closer to gaining a fully comprehensive understanding and greater ability to predict the characteristics of uncontrolled spacecraft reentry
and breakup incidences so that accurate safety precautions can be put into place in advance.
