Shipping Trouble

We keep getting delayed due to shipping, which is pretty frustrating. First, we had to wait to get the card cages sent from Berkeley. As soon as we got those last week, we thought there was nothing preventing us from getting the cryostat on the gondola. But that was before we noticed that our stycast (thermal epoxy) had dried out. We need the stycast to attach heaters and temperature sensors to the cryostat, the electronics boxes, and the gondola. Continue reading

Sunday Funday

On our first day here, some of us took a pact to take a day off every week: Sunday funday! (If the weather is bad one Sunday we can do a Monday funday instead – it still rhymes). Yesterday most of us hiked near the Rob Roy glacier and got some great views. Here are some pictures from the day. Continue reading

First week in Wanaka

Not too much has happened this week. We’re still waiting for some of our card cages (the electronics that read out the detector signals) to get here from Berkeley. They got shipped separately from the rest of the instrument because we wanted to work with them during the month it took the container to get here. Once we get the card cages, we’ll be able to turn on the rest of the detectors, and start putting them on the gondola. Continue reading

COSI’14 Recovery (long overdue)

Balloon payloads are effectively reusable. You launch your instrument once, after the flight is terminated it lands with the assistance of a parachute, you go out and pick it up, take it back to the lab for repairs/upgrades, and then you’re able to launch it again often within a year or two. So, with such a short flight and a close landing it would be pretty likely that we could recover the entire COSI instrument in the remainder of the Antarctic summer season. Continue reading
