Space, the final frontier, sure is expensive to explore. Every launch, every mission, can cost billions of dollars in research, materials, and overhead. And partly because of this, government space agencies may be especially susceptible to corruption. After all, these agencies are responsible for enormous projects with thousands of moving parts (literally and figuratively), but are monitored principally by committees that lack the scientific knowhow to conduct effective oversight. Embezzlement, overspending, bribery, and other crimes are easy to miss. Not only is corruption easily buried by bureaucratic or technical minutiae, it’s also extremely costly, as mistakes can result in the loss of valuable equipment or even human life. Even when corruption causes things to go wrong, the fact that space missions are inherently risky and complex may make it difficult to recognize when a malfunction is due to malfeasance.

Roscosmos, the Russian state corporation responsible for space flights, serves as a cautionary tale. For years, Roscosmos funds have been embezzled though contracting bids— officials were bribed to make fake deals and artificially inflate costs, allowing hundreds of millions of dollars to evaporate and a few Soyuz rockets to accidentally explode. (In 2014 alone, corruption and other malfeasance caused Roscosmos to lose roughly US$1.8 billion.) After Russian anticorruption activist Alexei Navalny called out the “astronomic” levels of corruption and mismanagement at the Vostochny space center (one of President Putin’s pet projects), multiple criminal investigations resulted in the conviction and sentencing of fifty-eight officials for fraud and abuse of office.

Though the record of the U.S. National Aeronautics and Space Administration (NASA) is not nearly as egregious, neither is it pristine. Suspicions regarding bribes by private contractors to NASA officials have existed for decades. For instance, back in the mid-1990s, a controversial FBI sting operation implicated dozens of contractors that allegedly paid bribes to NASA employees in hopes of determining which commercial experiments would be selected for the International Space Station. Representative John Conyers, who chaired the Committee on Government Operations in the House of Representatives at the time, pinned the blame on “NASA’s dismal record of contract mismanagement and faulty financial controls.” And the problems haven’t gone away: just last year, NASA’s associate administrator for human spaceflight Doug Loverro resigned amid allegations for improper contacts with Boeing regarding the contracts for NASA’s moon lander program. NASA’s Office of the Inspector General (OIG) has raised numerous concerns about NASA’s procurement system, and NASA attributed the Taurus XL launch failures, worth $700 million, to faulty materials provided by a contractor that falsified thousands of certifications for their aluminum products.

Though NASA has since taken some measures to curb against the potential for this sort of corruption (such as the installation of a Chief Financial Officer and the Acquisition Integrity Program), the risks are still significant, especially as NASA ponders a return to crewed missions by way of billion dollar contracts. These risks are further exacerbated by the agency’s even greater reliance on private sector contractors to compensate for the decline in the agency’s budget. There are therefore several additional steps that NASA can and should take to further safeguard integrity in the procurement process.
