In the first memorial of its kind, NASA and the families of the 14 men and women who lost their lives aboard the shuttle Challenger in 1986 and Columbia in 2003 have joined together to remember the astronauts with pictures, personal mementos and, in an emotional first, iconic wreckage from both orbiters.
Now just three weeks from its historic flyby of Pluto, NASA’s New Horizons spacecraft is close enough to detect objects smaller and dimmer than the dwarf planet’s smallest known moon and so far, nothing has been spotted that would pose a threat to the probe as it barrels through the system at more than 30,000 mph, scientists said Tuesday.
Flying more than twice the speed of sound 34 miles above Hawaii, a flying saucer-shaped test vehicle successfully inflated a doughnut-like airbrake, technology needed to slow heavy payloads down during descent to Mars, but a parachute ripped apart in the $230 million program’s second straight failure.
Taking a major step toward an eventual robotic mission to Europa, a moon of Jupiter believed to harbor ice-locked lakes and a vast sub-surface ocean, NASA has selected nine sophisticated instruments for a solar-powered spacecraft designed to find out whether the hidden realm could support life of some sort, agency officials said Tuesday.
