Nearly a dozen scientists associated to nuclear and area protection packages tied to NASA, SpaceX, and Blue Origin are useless or lacking in circumstances way back to 2022, and so they’ve gone largely unnoticed by authorities and the general public—till now.
The Home Oversight Committee formally demanded solutions from 4 federal companies Monday on the deaths and disappearances of a minimum of 11 American scientists and researchers with ties to NASA, nuclear analysis, and labeled protection packages—a number of of them straight related to the area protection applied sciences now being commercialized by SpaceX and Blue Origin.
Committee Chairman James Comer (R-Ky.) and Rep. Eric Burlison (R-Mo.), the chair of the Subcommittee on Financial Development, Power Coverage, and Regulatory Affairs, despatched letters to FBI Director Kash Patel, Secretary of Power Chris Wright, Secretary of Protection Pete Hegseth, and NASA Administrator Jared Isaacman, requesting staff-level briefings no later than April 27.
“If the reports are accurate, these deaths and disappearances may represent a grave threat to U.S. national security and to U.S. personnel with access to scientific secrets,” the letters learn.
Afterward Monday, Comer mentioned the string of deaths was unlikely to be a coincidence. “Once you see the facts, it would suggest that something sinister could be happening and it would be a national security concern,” Comer mentioned, including he and Burlison had been seeking to “see if we can put it together and find any missing links to try to solve what’s going on here. Because it’s very unlikely that this is a coincidence. Congress is very concerned about this. Our committee is making this one of our priorities now because we view this as a national security threat.”
White Home responds
The White Home formally acknowledged the sample on April 15, when press secretary Karoline Leavitt was requested straight about it at a briefing. “If true, of course, that’s definitely something I think this government and administration would deem worth looking into,” she responded.
Later that day, President Trump instructed reporters, “I don’t know. Hopefully, coincidence, whatever you want to call it. But some of them were very important people,” including he would have solutions inside “the next week and a half.”
“I just left a meeting on that subject, so pretty serious stuff.”
In a put up on X two days later, Leavitt confirmed the administration “is actively working with all relevant agencies and the FBI to holistically review all of the cases together and identify any potential commonalities that may exist,” including, “No stone will be unturned.”
“If there’s any connections that lead to nefarious conduct or conspiracy, this FBI will make the appropriate arrest.”
The bureau instructed Fortune in a press release, “The FBI is spearheading the effort to look for connections into the missing and deceased scientists. We are working with the Department of Energy, Department of War, and with our state and local law enforcement partners to find answers.”
When requested for remark, NASA directed Fortune to its first official assertion on the matter in an X put up. “NASA is coordinating and cooperating with the relevant agencies in relation to the missing scientists. At this time, nothing related to NASA indicates a national security threat. The agency is committed to transparency and will provide more information as able.”
SpaceX and Blue Origin, and the scientists concerned
The committee’s letters give attention to NASA and nuclear analysis connections, however the broader context is the industrial space-defense business that these scientists helped construct. The planetary protection and nuclear analysis fields are notably insular: There are solely a pair hundred scientists who focus on asteroid characterization, deflection modeling, and space-based detection.
Blue Origin unveiled its NEO Hunter planetary protection idea in March 2026, developed in partnership with California’s Jet Propulsion Laboratory (JPL) and Caltech and constructed on its Blue Ring spacecraft platform. The ion-beam deflection and kinetic impression capabilities it proposes share core expertise with missile-defense detection and interception techniques.
Each firms have obtained substantial federal contracts below the Trump administration. House Pressure awarded SpaceX practically $6 billion and Blue Origin roughly $2.3 billion in nationwide safety launch contracts in April 2025. SpaceX is individually below contract for the Golden Dome missile protection satellite tv for pc constellation; Blue Origin has been added to the $151 billion SHIELD contract via the Missile Protection Company and employed its first-ever president of nationwide safety in December 2025.
NASA Administrator Isaacman, one of many 4 letter recipients, has championed the enlargement of the privatization of missions beforehand managed by authorities companies. Neither SpaceX nor Blue Origin responded to Fortune’s requests for remark.
The letters flag an in depth skilled tie between two of the lacking: Aerojet Rocketdyne and JPL engineer Monica Reza and retired Air Pressure Maj. Gen. William Neil McCasland, each of whom vanished, in 2025 and 2026 respectively. The letters observe that the 2 labored collectively on “an Air Force–funded research program in the early 2000s pertaining to advanced materials needed for reusable space vehicles and weapons,” which Comer and Burlison say has not been defined.
Deaths and disappearances
The circumstances date again to 2022 and span JPL, Los Alamos Nationwide Laboratory, MIT, Caltech, and the Kansas Metropolis Nationwide Safety Campus. Reza, 60, was director of JPL’s supplies processing group and had patented a nickel super-alloy utilized in each area journey and weaponry when she vanished throughout a hike on Angeles Crest Freeway in June 2025 and was by no means discovered. She patented a nickel super-alloy for rocket manufacturing, analysis that went into reusable rocket packages like New Glenn and Starship. McCasland, 68, disappeared from his Albuquerque residence on Feb. 27 of this 12 months, leaving on foot with solely a .38 caliber revolver.
JPL principal scientist Frank Maiwald, 61, died on July 4, 2024, with no explanation for loss of life launched and no assertion from NASA. Authorities contractor Steven Garcia, who oversaw nuclear weapons property on the Kansas Metropolis Nationwide Safety Campus, disappeared from Albuquerque in August 2025, final seen on surveillance footage leaving on foot with a handgun.
Michael Hicks, who labored at JPL from 1998 to 2022, handed away in July 2023 at age 59. He labored on asteroid characterization analysis that was utilized in NASA’s Double Asteroid Redirection Take a look at (DART) mission, and was the identical methodology that Blue Origin’s NEO Hunter was modeled on and SpaceX’s Falcon 9 initially launched in 2021. Caltech astrophysicist Carl Grillmair was discovered shot useless on his entrance porch in rural Llano, Calif., earlier this 12 months. The 67-year-old labored on NEOWISE and NEO Surveyor telescopes which are the detection spine utilized by NEO Hunter. SpaceX is contracted to hold NEO Surveyor to orbit on a Falcon 9 in 2027.
Two Los Alamos Nationwide Laboratory workers, Anthony Chavez and Melissa Casias, vanished weeks aside in 2025 below practically an identical circumstances, every forsaking their automobile, keys, pockets, and telephone. Jason Thomas, an assistant director at Novartis with energetic DOD contracts, disappeared in December 2025 and was discovered useless in a Massachusetts lake three months later.
Former FBI official Chris Swecker not too long ago shared that the sample is according to how “several foreign powers” function, by “abducting, blackmailing, torturing, and even killing” scientists to realize intel.
