GUSTO is a balloon observatory that will drift in the Earth’s atmosphere for over 75 days at the edge of space at 36 km altitude, simultaneously mapping three types of material in the gas and dust between stars. SRON and TU Delft developed all three detector arrays for this NASA mission. The final two flight arrays have now passed their pre-shipment review and have been shipped to the University of Arizona for integration into the balloon observatory. Together with the earlier shipped array for 4.7 terahertz, the 1.4 and 1.9 terahertz arrays complete GUSTO’s flight detector.
