NASA’s GOLD instrument captures its first image of the Earth

NASA’s Global-scale Observations of the Limb and Disk, or GOLD, instrument powered on and opened its cover to scan the Earth for the first time, resulting in a “first light” image of the Western Hemisphere in the ultraviolet. GOLD will provide unprecedented global-scale imaging of the temperature and composition at the dynamic boundary between Earth’s atmosphere and space.

The instrument was launched from Kourou, French Guiana, on Jan. 25, 2018, onboard the SES-14 satellite and reached geostationary orbit in June 2018. After checkout of the satellite and communications payload, GOLD commissioning—the period during which the instrument performance is assessed—began on Sept. 4.

Team scientists conducted one day of observations on Sept. 11, during instrument checkout, enabling them to produce GOLD’s “first light” image. Commissioning will run through early October, as the team continues to prepare the instrument for its planned two-year science mission.

GOLD launches successfully onboard SES-14 satellite

UPDATE: SES-14 in good health and on track despite launch anomaly

NASA’s Global-scale Observations of the Limb and Disk (GOLD) instrument, designed and built by LASP, launched today from Kourou, French Guiana aboard SES-14, a commercial communications satellite built by Airbus Defence and Space. GOLD will investigate the dynamic intermingling of space and Earth’s uppermost atmosphere—and is the first NASA science mission to fly an instrument as a commercially hosted payload.

Space is not completely empty: It’s teeming with fast-moving charged particles and electric and magnetic fields that guide their motion. At the boundary between Earth’s atmosphere and space, the charged particles— called the ionosphere—co-exist with the upper reaches of the neutral atmosphere, called the thermosphere. The two commingle and influence one another constantly. This interplay—and the role terrestrial weather, space weather and Earth’s own magnetic field each have in it—is the focus of GOLD’s mission.

GOLD team successfully completes environmental testing

NASA’s Global-scale Observations of the Limb and Disk, or GOLD, instrument has successfully completed environmental testing at Airbus in Toulouse, France, in preparation for its groundbreaking mission to observe the nearest reaches of space. Scheduled for launch in late January 2018, GOLD will measure densities and temperatures in Earth’s thermosphere and ionosphere.

GOLD is a NASA Mission of Opportunity that will fly an ultraviolet imaging spectrograph on the SES-14 geostationary commercial communications satellite, built by Airbus for SES. The two-channel imaging spectrograph—designed and built at LASP—will explore the boundary between Earth and space, a dynamic area of near-Earth space that responds both to space weather from above and to weather in the atmosphere from below.

GOLD installed on commercial communications satellite

A LASP-built instrument that will provide unprecedented imaging of the Earth’s upper atmosphere has been successfully installed on the commercial satellite that will carry it into geostationary orbit some 22,000 miles above the Earth.

The Global-scale Observations of the Limb and Disk (GOLD) mission, led by the University of Central Florida (UCF) and built and operated by LASP, features a collaboration with satellite owner-operator SES Government Solutions (SES GS) to place an ultraviolet instrument as a hosted payload on a commercial satellite.

GOLD one step closer to launching into space

A NASA instrument that will study the upper atmosphere and the impact of space weather on Earth is a step closer on its journey into space.

The Global-scale Observations of the Limb and Disk (GOLD) mission, led by University of Central Florida (UCF) scientist Richard Eastes, is scheduled to launch in late 2017 from Florida. Earlier this month, the LASP-built instrument was shipped to Airbus Defence and Space in Toulouse, France, for integration on the SES-14 communications satellite, on which it will be launched into space.

PRESS RELEASE: GOLD Approved for Final Design and Fabrication

The Global-scale Observations of the Limb and Disk (GOLD) mission, part of the NASA Explorers Program, passed a rigorous examination on March 5th at the Goddard Space Flight Center in Maryland, enabling the mission to move into the final design and fabrication phase.
