New equipment developed in Brazil - the Solar-T - will be sent to the International Space Station (ISS) to measure solar flares. It is estimated that the Sun-THz, the name given to the new photometric telescope, will be launched in 2022 on one of the missions to the ISS and will remain there to take consistent measurements. The telescope contains graphene sensors that are highly sensitive to terahertz frequencies, able to detect polarization and be adjusted electronically.
The Sun THz is an enhanced version of the Solar-T, a double photometric telescope that was launched in 2016 by NASA in Antarctica in a stratospheric balloon that flew 12 days at an altitude of 40,000 m. The Solar-T captured the energy emitted by solar flares at two unprecedented frequencies: from 3 to 7 terahertz (THz) that correspond to a segment of far infrared radiation. The Solar-T was designed and built in Brazil by researchers at CRAAM together with colleagues at the Center for Semiconductor Components at the University of Campinas (UNICAMP). The new equipment will be the product of a partnership with the Lebedev Physics Institute in Russia.
