Faster, NASA, Faster – NYT Op-Ed
In Silicon Valley we have a saying: launch early, launch often. It’s an acknowledgment that successful, innovative companies are the ones that rapidly try new ideas, see what works, improve their products and repeat.

CSIS has launched a high-level Commission, co-chaired by former Secretary of Defense William Cohen and Hank Greenberg of C.V. Starr & Company, to help shape a more constructive and effective American approach to the U.S.-China relationship.
Gravitational tractor for towing asteroids – Nature
We present a design concept for a spacecraft that can controllably alter the trajectory of an Earth-threatening asteroid by using gravity as a towline. The spacecraft hovers near the asteroid, with its thrusters angled outwards so that the exhaust does not impinge on the surface. This proposed deflection method is insensitive to the structure, surface properties and rotation state of the asteroid.
Asteroid Tugboat – Scientific American
On an average night, more than 100 million pieces of interplanetary debris enter Earth’s atmosphere. Luckily, most of these bits of asteroids and comets are no bigger than small pebbles; the total weight of the 100 million objects is only a few tons. And our planet’s atmosphere is thick enough to vaporize the vast majority of these intruders.
