As far as I know, I'm the first real instrument that has been used for maximum likelihood polarization analysis!
The 2nd paper is about polarization analysis using the maximum likelihood method. t.co/DiUy6izPOE
Alex wrote two papers about me that were accepted to ApJ! One is about polarization analysis of the GRB I detected: t.co/T5YO0ZyElz

@stratoballoon Actually it's good that I was disassembled! That way I'm less likely to break during transport.

Floating at 222mph. Fastest lap at #Indy500 was 225. @AlexanderRossi isn't the only NorCal speedster! I should learn to steer! 🏁
Today I passed over Chile and am currently floating over Argentina. Signing out for the night. ¡Buenas noches!

Last year the first snow in Wanaka was on May 25. I hope I'm in space before the first snow this year!
No launch tomorrow. Looks like I'll be enjoying Wanaka for a little longer...
@dannycbowman the high altitude winds are good until July / August. I will launch someday!
I've been flight ready for month and a day. Too bad the weather doesn't look good for tomorrow or the day after. I blame El Niño.
Just sitting here getting calibrated. Unfortunately the weather isn't good for launching me in the next few days 🙁

What did we do while waiting for a good launch opportunity?... t.co/1Lh9bqh4nH
@dannycbowman - the payload was on the runway but the balloon stayed inside.

I might launch tomorrow morning, probably around 9 AM New Zealand time (2 PM pacific time). Stay tuned for updates
No launch tomorrow or the next day. But maybe, just maybe, a chance for Wednesday morning (New Zealand time)
Thanks for the good luck chocolate, Maïca!! I only eat electricity, but my team thought the chocolate was great 🙂

I might get launched tomorrow! The launch window is 8am - 10am New Zealand time (1-3pm pacific time). Stay tuned!
