(9)NASA’s rover Curiosity successfully carried out a highly challenging landing on Mars early Monday, transmitting images back to Earth after traveling hundreds of millions of miles through space to explore the red planet. Scientists praised the landing Monday. "This is a stunning achievement. The engineering went flawlessly," said Scott Hubbard, who was the first Mars program director at NASA headquarters and is now a consulting professor at Stanford University. The 10 science instruments aboard Curiosity are in "perfect health," and testing and calibration are under way, NASA said on Monday.
    Some rover team specialists are analyzing the data from the landing, while others are preparing Curiosity for exploring Gale Crater, where it landed, NASA said.(10)On its first full day on Mars, the rover is tasked with raising its high-gain antenna, enabling it to communicate directly with Earth at higher data rates. The primary method of transmitting data is through the orbiters, because that is more energy-efficient.
    When asked whether anything had gone wrong during the landing, Jennifer Trosper, a mission manager with NASA’s Jet Propulsion Laboratory in California, said simply, "No. There’s a lot ahead of us, but so far we are just ecstatic about the performance of the vehicle," she told reporters at an afternoon news conference.
