The big news for today is that Laird and Katie cabled, plumbed, and powered-up the ASM. We’ve never done that before without at least one Arcetrian in the room. It all went very smoothly, and the ASM is ready to go on sky!
Our day started with Oscar introducing us to the Cherimoya. It’s a really flavorable sweet fruit. We also had fresh squeezed Cherimoya juice for breakfast.
We started switching over to a night schedule. That means we got up for breakfast at 7:30 and worked until 2 am. We finished out the night testing some new plumbing fixtures for the NAS. At least we’ll sleep in a little this morning.
MagAO has produced another Ph.D.! Kate successfully defended her dissertation on Thursday, at the very un-Astronomer hour of 9 am. Nevertheless her talk was well attended, and all of that hard work paid off. Congratulations to Dr. Kate Follette, Queen of VisAO SDI.
Now that the fun is over, Laird,Katie, and Jared are heading down to LCO for MagAO’s 2014B science run. Our flight leaves Tucson this afternoon. We get the telescope for 37 nights, and we’ll be down there for 6 weeks. That means you get over 40 blog posts in a row. Lucky!
I’m feeling the need for some motivation. It’s time for us to pull our (steel-toe) boots on, lace ’em up, and earn our pay. Here’s what we’ll be singing as we march up to the telescope every day for the next 6 weeks.
This past week the NASA Exoplanet Science Institute (NExSCI) hosted the 2014 Sagan Summer Workshop, which was on Imaging Planets and Disks. Several members of the MagAO team and extended family attended, and presented some of our latest and greatest results. The workshop was held on the campus of Caltech, in Pasadena.
We all learned a lot, and had some fun. Thanks to the whole NExSCI crew for putting on such a great workshop.
The real star of the show was Space Shuttle Endeavour, which has retired to the California Science Center. We took Wednesday afternoon off to go see her, and it was amazing.
At one point while preparing for my thesis defense, I was faced with a conundrum: work on my dissertation or do something else. So what I did was research my academic lineage. It goes something like:
Jared Males –> Laird Close –> Don McCarthy –> Frank Lowe –> (a bunch of nerds at MIT) –> Robert Millikan –> Albert Michelson.
No disrespect to everybody else, but those last two dudes are pretty big deals. Well, since I was at Caltech, I went and paid Dr. Millikan a visit.
I also visited the other famous residents of the campus.
I’m on Mauna Kea visiting Olivier Guyon and the Subaru Coronagraphic Extreme AO (SCExAO) system. At 13,800 feet I’m pretty sure this is the highest altitude pyramid AO system in the world. Despite having a pyramid wavefront sensor, SCExAO is a pretty different AO system from MagAO. For one thing, there isn’t an adaptive secondary. Instead, the deformable mirror is on an optical bench off to the side. SCExAO is also not the only AO system – before light gets to SCExAO it has been corrected by the AO188 system, which is the AO workhorse of the Subaru telescope.
SCExAO hosts several science cameras, including VAMPIRES and FIRST which are being engineered on this run. I’ve also seen some impressive demonstrations of low-order wavefront sensing, focal plane wavefront sensing, and speckle nulling. SCExAO has some really exciting high contrast imaging capabilities.
As you can see, the SCExAO team is very creative with their camera displays. They consider Chuck Norris to be their spiritual leader, though somebody seems to like My Little Ponies.
Mauna Kea is high, and the air is thin up here.
We stay at Hale Pohaku (HP), which is at a more comfortable 9000 feet.
One thing that I learned during this visit is that if Olivier ever asks you to go for a walk, you say NO. What he considers a “walk”, most people would consider “rock climbing in the dark”.
The view is amazing from up here.
Being back in Hawaii reminds me of old times. The song of the day describes one of life’s enduring mysteries, which I still have little insight into.
We have observed our last target star of the 2014A run. It was another great night, with half arcsecond seeing almost the whole way.
We now have 2 days of packing and storing and inventory to do, and then we start the long journey home. Laird and Katie got started as soon as the dome closed.
We have to spend some time saying goodbye to all of our friends. We won’t see them for 6 months!
And we need to spend some time actually looking at the night sky, it’s so beautiful here.
We spent a lot of time on this run trying to mitigate the effects of diffraction. So check out the wave nature of these guitar strings:
