WASHINGTON – For the first time, Earth has a regular orbiting eye-in-the-sky spying on the solar system's smallest and strangest planet, Mercury.
NASA's spacecraft called Messenger successfully veered into a pinpoint orbit Thursday night after a 6 1/2-year trip and 4.9 billion miles and tricky maneuvering to fend off the gravitational pull of the sun. It is the fifth planet in our solar system that NASA has orbited, in addition to the Earth and the moon.
"It was right on the money," Messenger's chief engineer, Eric Finnegan, said. Messenger is in orbit that brings it as close as 120 miles above the planet's surface. "This is as close you can possibly get to being perfect."
"Everybody was whooping and hollering; we are elated," Finnegan said. "There's a lot of work left to be done, but we are there."
