When President Barack Obama earlier this month announced a new $100m year brain initiative, it was no surprise the White House would tap agencies like the National Institutes of Health and the National Science Foundation to help lead the effort. Less obvious, at least to some, was the role of the Defense Advanced Research Projects Agency (Darpa), a military agency that is perhaps better known for its development of weapons like stealth aircraft than medical technology.
That an agency founded over 50 years ago as the original space agency—before Nasa was created—would now become a leading government agency for brain research might be unexpected, but it is perhaps in line with an usual history that has spanned early work on spy satellites to current effort to help develop cyber weapons.
Darpa is an agency that has continuously reinvented itself, and this week may be another part of its story.
At a Pentagon briefing, Arati Prabhakar, the current head of Darpa, announced the release of a “framework” that spells out the agency’s role. “Our mission is unchanged, in 55 years, it has been and will be to prevent and create technological surprise,” she said, in announcing the new plan. “But of course the world in which we do that has changed many times since 1958.”
Darpa was founded in 1958 as the Advanced Research Projects Agency (the “D” for defense was added in the 1970s), an expedient way to manage civil and military space programs in the chaotic days after the launch of the Soviet Sputnik satellite. When Nasa was formed, it took over the civil space programs from Darpa, and military space programs soon went back to the military services.
Rather than shut its doors, Darpa moved into a series of high-risk, and often futuristic science and technology programs, pursuing research in ballistic missile defense, computer science and counter-insurgency. In fact, many of Darpa’s biggest early achievements—such as a satellite system for detecting nuclear tests—are today obscure to a generation that has grown up during a US and Russian moratorium on nuclear weapons testing.
Of course, the dilemma of explaining—or in some cases defending—Darpa’s research, is that its applications aren’t always clear in the early stages. In the 1980s, Malcolm Wallop, a Republican senator from Wyoming, blasted the agency for spending money on super computers, saying that it should be investing in weapons—a criticism that ended up being terribly short sighted given the current importance of computing to almost all weapons.
Those questions aside, Darpa’s funding of the Arpanet, a precursor of the internet, an early prototype of stealth aircraft, and the Global Positioning System (GPS), have all contributed to making it something of a household name. The agency has also enjoyed recent publicity for some of its more far-out research, such as the Cheetah robot, a four-legged robot that can run at 46km/h (29mph).
Darpa is widely hailed as a success story—so much so, in fact, that its model of innovation has been copied—at least in name, among other government agencies, through the creation of “Arpas” for energy, intelligence, and homeland security. Even Russia recently launched its own version of Darpa, though few, even in Russia, expect it to have the funding or reach that the original agency enjoys.
But even with public and political support, Darpa also faces cuts as part of sequestration, a budget deal that makes across-the-board reductions in spending. In recent congressional testimony, Prabhakar said that the agency was planning to delay one of its new cybersecurity programs, known as Plan X, by five months as a result of the budget reductions.
