Japan launched a rocket carrying a government satellite designed to transmit data collected by reconnaissance satellites already in orbit on Sunday, enabling faster, richer communication when responding to natural disasters.

The H2A rocket, operated by Mitsubishi Heavy Industries Ltd. and the Japan Aerospace Exploration Agency, took off in the afternoon from the Tanegashima space center in Kagoshima prefecture in southwestern Japan.
The relay satellite will initially conduct test transmissions of data acquired by the fleet of information-gathering satellites, returning them from its position in geostationary orbit via optical communication.
When in operation, it will help overcome the problem that data can only be received for a limited time when each observation satellite has a direct line of sight with a grounded receiver.
By sending data, including images and other information, via the broadcast satellite, transmissions can be done more flexibly and for a longer time from each observation satellite, JAXA said.
