Gotta say that I'm enjoying the JHU/APL broadcast. Very slick. Live audience adds a nice element. smile.gif

End of main burn, tweaking now.

Edit: Lots of clapping, handshakes, looks like everything went just perfectly! Waiting on data from spacecraft to confirm.

Edit2: High rate telemetry is being received. We know now the burn did last as long as expected.

Edit3: Official confirmation of successful MOI burn. Made the target to within 0.5-sigma.

Was super busy all day today, and just now came to this thread, and with a rising sense of anticipation, read all the posts.

Whew! And attaboys and 'ham sammiches' to everyone!


I did go out the other night to see Mercury and Jupiter after sunset, and was hoping all was well.

Itokawa was too small. Hayabusa didn't do much orbiting, only station keeping in solar orbit

Congrats! Great to hear that it worked!

@Volcanopele you can find good spice kernels on the NAIF FTP site in the PDS folder for use in Celestia, including the main mission period.

Fantastic news! And if you haven't seen it already, Emily has made an absolutely gorgeous pic for her blog, showing Mercury's size compared to other familiar bodies in the solar system...
