nasa will test a key deep space navigation tool this year




see, the atomic clocks space agencies and companies use today need to be paired with ground-based antennas. the antenna sends signals to a spacecraft, and the vessel sends them back to earth. current clocks use the difference in time between sending and receiving a signal to calculate a space vehicl...

how to build a space communication system out of lasers




in october 2013, a moon-orbiting nasa spacecraft aimed a laser beam at earth, 239,000 miles away. within seconds, the intended recipient—an observatory in southern california—locked onto the beam of infrared light, invisible to the naked eye. encoded inside the light was a high-definition video ...



nasa communications satellite damaged 3 weeks before launch




nasa's newest, slickest communications satellite has been damaged, just three weeks before its planned august launch. nasa said monday that one of the antennas on the tracking and data relay satellite, or tdrs-m (t-driss-m), was damaged last friday. the accident occurred inside a payload processing ...



cloudy with a chance of radiation: nasa studies simulated radiation




in each life a little rain must fall, but in space, one of the biggest risks to astronauts' health is radiation "rain". nasa's human research program (hrp) is simulating space radiation on earth following upgrades to the nasa space radiation laboratory (nsrl) at the u.s. department of energy's brook...
