Powered by low-enriched uranium, the engine’s fission reactor will heat and vaporize liquid propellants, capturing the gases out of a nozzle to present thrust. NASA will provide the engine and DARPA the experimental spacecraft that will carry it. The style and design plans contain a security review.

The report also finds that “NIH did not successfully watch or consider timely motion to address” complications with the project’s compliance, these kinds of as a 2-year hold off in a development report from EcoHealth that explained possibly dangerous virus experiments. And auditors concluded that EcoHealth’s checking of WIV eroded when the pandemic began and that EcoHealth experienced overbilled $90,000 in bills on NIH grants totaling $8 million from 2014 to 2021. EcoHealth responded that the audit “did not uncover important issues” in its general performance. NIH stated it is strengthening its oversight.
