Japan's new solid-fuel rocket blasted off Saturday carrying a telescope for remote observation of planets in a launch coordinated from a laptop computer-based command centre.
The Japan Aerospace Exploration Agency (JAXA) launched the Epsilon rocket from the Uchinoura Space Centre in Kagoshima, southwestern Japan, at 2:00pm (0500 GMT), live footage showed.
Lift-off had originally been scheduled for 27 August, but the first attempt was suspended with just seconds to go after a ground control computer falsely detected a positional abnormality.
Japan hopes the rocket, launched with just two laptop computers in a pared-down command centre, will become competitive in the global space business.
The three-stage Epsilon — 24 metres (79-feet) long and weighing 91 tons — was scheduled to release the "SPRINT-A" telescope at an altitude of 1,000 kilometres (620 miles).
JAXA is expected to comment whether the launch was a success after confirming the release of the telescope.
SPRINT-A is the world's first space telescope for remote observation of planets including Venus, Mars and Jupiter from its orbit around Earth, according to JAXA.
