Live coverage: Japan’s enhanced Epsilon booster blasts off

December 20, 2016 Stephen Clark

A Japanese Epsilon rocket launched Tuesday from the Uchinoura Space Center, a shoreline spaceport on the southern Japanese island of Kyushu, with a space weather research probe to study phenomena inside the turbulent Van Allen radiation belts. Liftoff of the 85-foot-tall rocket occurred at 1100 GMT (6 a.m. EST).
