Tiny Tim!!

Yesterday BLAST went outside to test things that don’t work inside: sun sensors, GPS, and telemetry. Notably, this required Tiny Tim—everybody’s favourite behemoth of a launch vehicle. […]

Outside Prep, LHe Filling Again

Yesterday we were doing lots of the little things we need to do before taking the gondola outside. Since the "we" doing lots of stuff occasionally includes "me", I can’t always be taking photographs of everything. So, most of what I have is from the first of the (third round of) liquid helium fills in the morning. […]

Arts and Crafts, Barbecue

Yesterday Elio, Barth, and I did some arts and crafts, preparing the solar panel mounts for use. In the evening we had a big barbecue with the EBEX folks, but I was too busy grilling to take photos. You can find one picture on twitter @BLASTPol […]

The Pub, The Night Shift

Because Enzo was leaving yesterday (or, rather, early today), we all went to the pub. During the day CSBF test fit their solar panels, which mainly involved loudly squealing with a hand drill while the mounts were modified. And Kyle test fit the new pinhole sun sensor mounts. Finally, like on all clear nights, Natalie and Laura were pointing the telescope and testing the star cameras. […]

Bread, Barth, and Biphase Bugs

I didn’t take many pictures yesterday, but I have saved a few non-cryogenic pictures from the cryostat-opening day earlier in the week. They’re mostly of Barth fixing biphase transmitter bugs, and of Enzo teaching Tristan the recipe he’s been using to make bread in the mornings. […]

Crafts and Cryostat Closing

Yesterday the cryostat was closed, with some modifications to help reduce microphonics. Preliminary signs (which are hard to determine while warm) are that things remain imperfect, but are quite possibly good enough. […]

Cryostat Open, Take 2

The biggest event yesterday was the second opening of the cryostat. This was to take a more careful look at the source of microphonic noise. Like last time, this involved poking things and rapping on the outside. Unlike last time, it was stripped down a lot further: to the JFET cavity, where detector signals are buffered on their way out of the cryostat. […]

Telecons, etc

Yesterday I was in code mode, so didn’t look much beyond my monitor, or take many pictures. But I did capture everyone’s favourite activity: morning teleconferences. And some other things. […]

Video Noise, Warmup

To start yesterday I caught some debugging of a different kind of noise: in the star camera video downlink. Otherwise we started to warm the cryostat, and some more work happened with the solar panels and mounts. […]

Fire Alarms, Sun Shields, and Rain

Yesterday fire alarms started going off in the highbay, so we spent some time outside. Later that evening, it rained a lot so we spent some time inside. In between we attached the sun shields to the gondola as a fit test. […]
