NASA’s Mission to Study Sunlight Completes Vacuum, Vibration Testing

A New Step Toward Measuring Solar Energy

NASA's TSIS-2 (Total and Spectral Solar Irradiance Sensor-2) spacecraft, built to study the sunlight reaching Earth, is reaching key pre-launch milestones. Maintained inside a clean room under the care of suited engineers, the satellite is undergoing intense preparations for space environment.

Crucial Vacuum and Vibration Testing Completed

Surrounded by test chambers and specialized machinery, the metallic hardware of TSIS-2 recently underwent thorough vacuum and vibration testing. These rigorous checks confirm that the satellite can survive the extreme shaking during launch as well as the vacuum of space.

Scientific Significance for Solar Radiation Studies

The TSIS-2 mission aims to measure total and spectral solar irradiance with high accuracy. The gathered measurements will help scientists better track variations in solar energy and understand their impacts on Earth's climate and atmospheric models.
