‘The science is terrible,’ he said ‘ A former Microsoft technologist questions NASA’s efforts to identify space rocks and their proximity to Earth.

Thousands of asteroids are passing through Earth’s neighborhood all the time. Although the odds of a direct hit on the planet any time soon are slim, even a small asteroid the size of a house could explode with as much energy as an atomic bomb.

So scientists at NASA are charged with scanning the skies for such dangerous space rocks. If one were on a collision course with our planet, information about how big it is and what it’s made of would be essential for deflecting it, or calculating the destruction if it hits.

For the last couple of years, Nathan P. Myhrvold, a former chief technologist at Microsoft, has roiled the small, congenial community of asteroid scientists by saying they know less than they think about these near-Earth objects. He argues that a trove of data from NASA they rely on is flawed and unreliable.
