“You need to have the ability for researchers and engineers to try out thousands of ideas,” says Hari Balakrishnan, the Fujitsu Professor in Electrical Engineering and Computer Science at MIT. “With this platform, you become constrained not by hardware or technological limitations, but by your creativity. You can innovate much more rapidly.”

Programmable network routers

New design should enable much more flexible traffic management, without sacrificing speed.

“We don’t necessarily want [air traffic controllers] to spend the bandwidth on processing 40 pieces of information. Instead, we can tell them the three top choices,” says Hamsa Balakrishnan, associate professor of aeronautics and astronautics at MIT and a member of MIT’s Institute for Data, Systems, and Society.

Ready for takeoff

Hamsa Balakrishnan develops algorithms to reduce airport congestion.

“It’s intuitive that if a bunch of people are randomly walking around an area, the number of times they bump into each other will be a surrogate of the population density,” says Cameron Musco, an MIT graduate student in electrical engineering and computer science. “What we’re doing is giving a rigorous analysis behind that intuition, and also saying that the estimate is a very good estim...

Clusters of four or more small satellites could look at a single location on Earth from multiple angles, and measure that location’s total reflectance with an error that is half that of single satellites in operation today, an MIT-led study suggests.

Better views with smaller satellites

Batches of shoebox-sized satellites could improve estimates of Earth’s reflected energy.
