The weather at Tanegashima probably won't be ideal for launch till May 25 (Tuesday). Darn.

I'd rather see a scrubbed launch than a failed launch like OCO. That was painful, watching the reactions of the team when they lost communications.

Brings to mind a question. When was the last time weather actually caused a launch failure on a significant mission?

There's the Atlas/Centaur-67 launch. I can't think of a more recent directly weather-induced failure.

Congrats to JAXA for the successful launch of Akatsuki and IKAROS (plus those 4 smaller satellites)! smile.gif

Initial Operation Result of
the Venus Climate Orbiter 'AKATSUKI'

May 21, 2010 (JST)
Japan Aerospace Exploration Agency (JAXA)


The Institute of Space and Astronautical Science (ISAS) of the Japan Aerospace Exploration Agency (JAXA) received the signal transmitted from the Venus Climate Orbiter "AKATSUKI" at the Uchinoura Space Center at 4:40 p.m. on May 21, 2010 (Japan Standard Time, JST), and confirmed that the scheduled sequence of events including the solar array paddle deployment and sun acquisition were successfully performed.

The AKATSUKI was launched from the Tanegashima Space Center at 6:58:22 a.m. on May 21, 2010 (JST)

The orbiter is currently in a healthy state.

We are preparing for the AKATSUKI injection into the Venus orbit in early December while checking functions of the onboard equipment and controlling the attitude and orbit.

We would like to express our profound appreciation for the cooperation and support of all related personnel and organizations that helped contribute to the successful launch and tracking and control operations of the AKATSUKI.

The Operation Status of
the Small Solar Power Sail Demonstrator 'IKAROS'

May 22, 2010 (JST)
Japan Aerospace Exploration Agency (JAXA)

The Japan Aerospace Exploration Agency (JAXA) acquired the signal transmitted from the IKAROS at the Usuda Deep Space Station and confirmed its solar power generation and stable posture, and established communications. We will turn on onboard devices one by one.

IKAROS moves to Verification Experiment Phase

May 24, 2010 (JST)
Japan Aerospace Exploration Agency (JAXA)

The Japan Aerospace Exploration Agency (JAXA) completed the initial
operation check of the Small Solar Power Sail Demonstrator "IKAROS,"
which was launched on May 21, 2010 (Japan Standard Time,) from the
Tanegashima Space Center.

We will take a few weeks to carry out the first verification
experiments, namely deployment of the solar sail and solar power
generation by thin film solar cells.

Here's a composite of the 3 first light images. I've added the LIR image as luminance (inverted) just for aesthetic effect.
