Telescope Details

Website

Location

Balloon experiment to be launched from Wanaka, New Zealand

Purpose

To conduct a wide-view measurement campaign of the cosmic microwave background, imaging 70% of the sky.

NIST’s role

NIST will design and build the full focal plane, including the detection elements and cryogenic readout.

Significant discoveries and current status

The experiment has not yet launched.

Other interesting facts

Taurus will use a NASA-designed “super pressure balloon” that will enable monthlong observations.
