Thrusters on farthest spacecraft fired up after 37 years
NASA has successfully tested the thrusters of its Voyager 1 spacecraft, the first ever man-made object to leave the solar system. Lying dormant since November 1980 after the spacecraft's launch in 1977, the thrusters were fired to test their ability to orient the spacecraft using 10-millisecond pulses. The test results from Voyager 1 took over 19 hours to reach Earth.
