Experts suspect a computer programming error and lax preliminary checks were among the reasons Japan's newest rocket didn't get off the ground Tuesday.

The computer controlling the launch of the three-stage Epsilon rocket at the Uchinoura Space Center in Kagoshima Prefecture detected an abnormality in the rocket's position only 19 seconds before its scheduled liftoff scheduled for 1:45 p.m., but it was later found to be normal.

Experts believe a computer programming error and lax preliminary checks were behind the trouble.
