This short BBC News item shows a very large high altitude balloon lifting a science payload to measure high energy cosmic rays for about 100 days, circling the Earth perhaps twice in the process.
Unfortunately I could not find any reference to the name of the mission or the payload. I'm wondering if there is a website or a map with it's current location as it circles the Earth.
I'm also looking for a short description of the cosmic ray detector itself. The payload looks really small and light, what kind of information can it record? Without a long or deep array, can it measure the angular distribution of the flux?
If each cell in the photovoltaic array is from a 6-inch wafer, I can use that as a scale to estimate the size of the two white "shoe boxes" sticking out on either side of the top of the payload as about 50x50x15 cm. Is this a two-element lateral telescope, looking for coincident detections through both? Can it point itself, or is rotation around the vertical axis random?
Up, up and away! Nasa's super soaring space balloon "This mega balloon - the size of a football stadium - was launched in New Zealand and will float around Earth for 100 days"
