Even in the face of unprecedented challenges, NASCAR has plenty of horsepower. The sport is three years into an eight-year, $4.5 billion television deal with Fox, ESPN/ABC and TNT. The steady TV revenue can help cushion sponsorship losses. NASCAR is still the second highest rated regular-season sport on...
Even though Phoenix was assembled in a special clean room to minimize bacterial contamination, and its arm, which would have direct contact with Martian ice, was heat-sterilized before launch, it's likely that dozens or more species of microbes hitched a ride on Phoenix's 10-month trip to...
That's why NASA planetary scientist Christopher McKay, in an article in this week's Science, suggests the need for a stronger policy that ensures all exploration of Mars be "biologically reversible" - meaning we would be required to effectively wipe away our footprints and remove any possibility of contamination, by...
For now, it's not difficult to make sure that we avoid squashing new life as we search it out - although doing so could add considerable cost to any space mission. Probes like Phoenix can be more fully sterilized before launch, and debris from any unmanned craft could eventually be...
