NASA has powered on its latest space payload to continue long-term measurements of the Sun’s incoming energy. The LASP-built Total and Spectral solar Irradiance Sensor (TSIS-1), installed on the International Space Station, is now fully operational with all instruments collecting science data.
TSIS-1 was launched from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida aboard a SpaceX Falcon 9 rocket on Dec. 15, 2017. After a two-week pause, the instrument suite was extracted from the trunk of the SpaceX Dragon capsule and integrated onto its permanent home on the space station.
We live on a solar-powered planet. As we wake up in the morning, the Sun peeks over the horizon to shed light on us, blanket us with warmth, and provide cues to start our day. At the same time, our Sun’s energy drives our planet’s ocean currents, seasons, weather, and climate. Without the Sun, life on Earth would not exist.
For nearly 40 years, NASA has been measuring how much sunshine powers our home planet. This December, NASA is launching a dual-instrument package to the International Space Station to continue monitoring the Sun’s energy input to the Earth system. The LASP-built Total and Spectral solar Irradiance Sensor (TSIS-1) will precisely measure total solar irradiance, a measurement required for establishing Earth’s total energy input. These data will give us a better understanding of Earth’s primary energy supply and help improve models simulating Earth’s climate.
A solar instrument package designed and built by LASP, considered a key tool to help monitor the planet’s climate, has arrived at NASA’s Kennedy Space Center in Florida for a targeted November launch.
The instrument suite is called the Total and Spectral solar Irradiance Sensor (TSIS-1) and was built for NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The contract value to LASP is $90 million and includes the dual instrument suite and an associated ground system to manage TSIS mission operations.
