The Triana mission, led by researchers at Scripps Institution of Oceanography at the University of California, San Diego, will collect key information about Earth’s climate system using the first deep-space climate satellite.
With new scientific instruments taking a broad set of measurements, the spacecraft will have a continuous view of the sunlit side of Earth from a vantage point 1.5 million kilometers away (at the L-1 neutral gravity point). This location will afford a view of the entire Earth, rather than a patchwork of regions of interest.
Triana’s measurements of infrared radiation emitted by Earth will be used to monitor global warming and climate variability. Triana will collect information about the climate system by tracking atmospheric dynamics, cloud physics, aerosols, radiation, and surface remote sensing.
Measurements of the solar wind, magnetic fields, and plasma will advance research and provide early warning of solar events that may pose threats to Earth. Solar-wind events will be "seen" by Triana approximately 50 minutes before reaching Earth’s magnetosphere–providing enough time to issue warnings to protect sensitive systems such as orbiting satellites.
Triana’s views of our world will be used as a teaching tool that will inspire the quest for knowledge. Triana team members will support this quest with public and elementary-to-higher education outreach, teacher training, and research opportunities for undergraduate and graduate students.
When Triana is launched (date undetermined), it will become the first deep-space "climate satellite" and has the potential to prove the unique usefulness of deep-space observation points such as L-1 and L-2 for earth sciences.
The Triana spacecraft and all instruments are built, tested, and calibrated.
Triana is ready to go.
Scripps Institution of Oceanography at the University of California San Diego, is one of the oldest, largest, and most important centers for global science research and education in the world. Now in its second century of discovery, the scientific scope of the institution has grown to include biological, physical, chemical, geological, geophysical, and atmospheric studies of the earth as a system. Hundreds of research programs covering a wide range of scientific areas are under way today on every continent and in every ocean. The institution has a staff of more than 1,400 and annual expenditures of approximately $195 million from federal, state, and private sources. Scripps operates oceanographic research vessels recognized worldwide for their outstanding capabilities. Equipped with innovative instruments for ocean exploration, these ships constitute mobile laboratories and observatories that serve students and researchers from institutions throughout the world. Birch Aquarium at Scripps serves as the interpretive center of the institution and showcases Scripps research and a diverse array of marine life through exhibits and programming for more than 430,000 visitors each year.
