A reasonable observer might choose other words: obsession, fantasy. Bill possesses neither great wealth nor extensive political connections. He is an engineer and runs Stone Aerospace, a company so small that when FedEx rings, he usually signs for the package himself. So to hear Bill talk—"It's not a big leap for me to go to Jupiter. For Bill, caves are a proving ground. The experience gained there will help people explore outer space.
But now, after spending nearly three decades on the margins of the space industry, Bill is closer than he's ever been to proving that caves are the best earthly training ground for exploring space. Backed by a $5-million fund from NASA, he is developing a robot called DepthX that may turn out to be the most advanced autonomous underwater vehicle (AUV) ever. NASA hopes to someday use a robot like Bill Stone's DepthX to explore Europa, a frozen moon of Jupiter and one of the most probably places in our solar system to support life. Like its inventor, DepthX is a caver, most capable of searching harsh environments. Its theoretical mission, though, is bold even by Bill's standards: a hunt for extraterrestrial(地球外的) life on Europa.
Innovator Bill Stone plans to drop one of the world's most advanced underwater robots, DepthX, into the deepest hole on Earth. If all goes well, this thing just might help get him to Europa DepthX's first major field trial will take place this month in Mexico's Zacatén Cenote, the world's deepest hole. For Bill's future space ambitions to have any chance, he needs to impress the new generation of wealthy space-loving investors. To do that, he needs to ace(取得好成绩) this first trial and, at 54 years old, he needs to do it fast. As one of his oldest friends puts it, "Time is running out for Bill."
What have Bill Stone and his teams accomplished？
A．They have explored many caves and reached the deepest cave in our planet.
B．They have sponsored the National Geographic Society to explore caves.
C．They have explored the outer space and set up funds for it.
D．They }rave explored and measured the deepest gave in Jupiter.
