The Japan Aerospace Exploration Agency (JAXA) will fire the engine of its Akatsuki probe for two seconds Sept. 7 and 20 seconds Sept. 14 as it works to get the craft into orbit around Venus after failing to do so in December, the Mainichi Daily News reported Sept. 6.

JAXA scientists are studying methods of sending fuel to Akatsuki’s engine without using a defective fuel valve that caused it to overheat, the agency said. They may attempt to adjust the probe’s posture in November as part of an effort to get it into venusian orbit in 2015.
