...TIME.com: How much did the Spirit mission cost, and has it been worth it? Kluger: The cost is $850 million, and we won't know whether it was worth it until the science is returned. But we do know that it's possible to get a spacecraft bigger and more sophisticated than Pathfinder there. And don't forget the old axiom that says there's no such thing as a failed experiment, because failures teach you what doesn't work...
...1960s? Kluger: The landing of Pathfinder on Mars in the summer of 1997 was the closest I've seen to people really gathering around TVs and being as excited as they were in the 1960s. There is potential for that feeling to return this summer, when the Cassini-Huygens spacecraft arrives at Titan, a moon circling Saturn...
...TIME.com: What's next on NASA's to-do list? Kluger: First, a continuation of the Mars program. The idea is to have a spacecraft ready to explore every two years, when Earth and Mars grow closer...
...making clean and sustainable power a mainstream commodity. For example, the fuel cell--which extracts electricity from the chemical reaction between oxygen and hydrogen--has been around for about 150 years, though its commercial deployment did not begin until the 1960s and then only as part of NASA spacecraft. Today this technology is coming down to Earth in places like Tokyo, where Japan's first hydrogen-fuel filling station opened in June; in nine European cities, from Stockholm to Porto, each operating three hydrogen-fuel-cell buses; and in Iceland, which is trying to create the first fossil-fuel-free...
CROSSED. The edge of the solar system; by VOYAGER 1, a 26-year-old spacecraft that has traveled farther than any other man-made object. Scientists differ on Voyager 1's precise location, but radio transmissions from the probe indicate that it has entered or is about to enter a turbulent border zone more than 13 billion kilometers from Earth called "termination shock," where matter from interstellar space slams into radiation emitted by the Sun. Data sent by Voyager 1 showed a marked drop in the speed of solar winds and a hundredfold increase in charged particles, some of which...
