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.
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.
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.
NASA’s MESSENGER mission to Mercury, carrying an instrument designed and built at LASP, is slated to run out of fuel and crash into the planet in the coming days after a wildly successful, four-year orbiting mission chock-full of discoveries.
The mission began in 2004, when the MESSENGER spacecraft launched from Florida on a 7-year, 4.7 billion mile journey that involved 15 loops around the sun before the spacecraft settled into orbit around Mercury in March 2011. LASP provided the Mercury Atmospheric and Surface Composition Spectrometer (MASCS), which has been successfully making measurements of Mercury’s surface and its tenuous atmosphere, called the exosphere, since orbit insertion.
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.
Analysis of data from the third and final fly-by of the MESSENGER spacecraft in September 2009 has revealed a treasure trove of new information on the solar system’s innermost planet. MESSENGER is on its way to Mercury, where it will settle into orbit in March 2011 and help scientists answer crucial questions about Mercury’s geology, density, structure, and magnetic field. Three fly-bys of the planet, spaced over twenty months, have been necessary to guide the spacecraft into its upcoming orbit around Mercury beginning in March 2011.
