AsianScientist (Dec. 17, 2015) – The Japan Aerospace Exploration Agency (JAXA) has successfully guided the Venus Climate Orbiter ‘AKATSUKI’ into the orbit circling around Venus.
As a result of measuring and calculating AKATSUKI’s orbit after its thrust ejection, the orbiter is now flying on the elliptical orbit at the apoapsis altitude of about 440,000 km and periapsis altitude of about 400 km from Venus. The orbit period is 13 days and 14 hours.
JAXA reports that AKATSUKI is in good health and that the orbiter is flying in the same direction as that of Venus’s rotation.
JAXA said it will deploy three scientific mission instruments, namely the 2μm camera (IR2), the Lightning and Airglow Camera (LAC) and the Ultra-Stable Oscillator (USO) and check their functions.
With these instruments, JAXA will perform initial observations. Observations will also be made with three other instruments whose function has already been confirmed: the Ultraviolet Imager (UVI), the Longwave IR camera (LIR), and the 1μm camera (IR1), for about three months.
At the same time, JAXA will also gradually adjust the orbit for shifting its elliptical orbit to the period of about nine days. The regular operation is scheduled to start in April, 2016.
