A father spoke to his son, "It's time we had a little talk, my son. Soon, you will have urges and feelings you've never had before. Your heart will pound & your hands will sweat. You'll be preoccupied and won't be able to think of anything else."
He added, "But don't worry, it's perfectly normal... it's called golf."
Mars probeIn 1997, the Mars Pathfinder, an unmanned space vehicle, reached the Martain atmosphere. It had taken seven months to travel there since its launch on 4 Dec 1996. Its main science mission was to study the Martian atmosphere and investigate the geology and chemical composition of the planet's rocks and soils. The descent was braked by a heat shield, a parachute and rockets. Using a new NASA effort for "cheaper, faster, better," the Mars Pathfinder used airbags to cushion its landing on the surface. It carried Sojourner, a 10-kg (22-lb) wheeled rover device designed to travel slowly across the surface of Mars taking photographs and collect other scientific data, while also testing autonomous-vehicle technology on the Martain terrain. |
