The GOLD instrument, which is short for Global-scale Observations of the Limb and Disk, 聽is expected to launch aboard a SpaceX Falcon 9 rocket from the Space Coast by the end of the year. The University of Central Florida is leading the mission; the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado at Boulder designed and built the instrument. 聽LASP will also operate the instrument during its two-year mission.

The mission is possible due to a joint agreement with SES Government solutions, which will provide the launch. The mission is a first-of-its-kind partnership between a university and commercial spacecraft operator to enable a NASA science mission. Such an approach may usher in a new era of similar projects giving universities nationwide broader access to getting science research into space.

The GOLD instrument will fly aboard an SES-14 satellite as a hosted payload. Hosted payloads enable NASA to make use of commercial satellite platforms as a new avenue for relatively low-cost science opportunities in space, according to NASA.

The successful integration of the ultraviolet 聽instrument onto the SES-14 satellite this month marks a milestone as the team prepares for launch. Next, the instrument and satellite will undergo a series of environmental tests at Airbus Defence and Space in Toulouse, France, before being shipped to Florida for final launch preparations.

麻豆精品 S淟aunch is almost within sight. The progress is exciting to see, and it 麻豆精品 S檚 getting even more exciting, 麻豆精品 S� said Richard Eastes, GOLD principal investigator and UCF scientist. 麻豆精品 S淚ntegration of the GOLD instrument has gone even better than I 麻豆精品 S檇 ever hoped. That 麻豆精品 S檚 a tremendous testament to the ability of the instrument and the satellite teams. 麻豆精品 S�

GOLD is designed to capture never-before-seen images of the Earth 麻豆精品 S檚 thermosphere and ionosphere, detecting changes in temperature and composition due to space weather activity. This is a critical step in understanding how to predict the impact of space weather events on Earth.

Some of the most dramatic space weather originates on the sun with ejections of plasma and X-rays into space. When directed at the Earth, ensuing geomagnetic storms have the potential to interfere with radio communication and disrupt GPS satellites, impacting everything from airline travel to high-tech farming, satellite TV programming and cell phone connections.

The GOLD mission will make measurements from a longitude of 47.5潞W during its two years of prime mission operations. The satellite has a life expectancy of 15 years.

In addition to building the UV instrument the size of a microwave oven, the Colorado laboratory is providing project management, systems engineering, safety and mission assurance, instrument operations, and public outreach for the mission. Eastes, who is based at UCF 麻豆精品 S檚 Florida Space Institute, oversees the project and is building the data center that will process and disseminate GOLD science data.

GOLD is a mission of opportunity and part of NASA 麻豆精品 S檚 Explorer Program. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the Explorer Program for NASA’s Science Mission Directorate in Washington. The Explorer Program seeks to provide frequent, low-cost access to space for NASA heliophysics and astrophysics missions requiring small to mid-sized spacecraft.

Other members of the GOLD team include the National Center for Atmospheric Research, the University of California at Berkeley, Computational Physics Inc., and the National Oceanic and Atmospheric Administration.

The information collected by the Global-scale Observations of the Limb and Disk (GOLD) mission will have a direct impact on understanding space weather 麻豆精品 S� such as solar wind 麻豆精品 S� and its impact on communication and navigation satellites, which we 麻豆精品 S檝e come to rely on for everything from television programming to cell phone coverage and GPS in our vehicles.

The information may also lead to advances in directing airline traffic in a safer manner by providing a greater understanding of how space elements impact communication signals.

麻豆精品 S淚t 麻豆精品 S檚 great to see something that my team and I have worked on for years selected for funding, 麻豆精品 S� said Richard Eastes, a research scientist with UCF 麻豆精品 S檚 Florida Space Institute. 麻豆精品 S淚t shows that other scientists think what we 麻豆精品 S檙e planning to do is some of the most important science in the world. And for UCF, it 麻豆精品 S檚 a chance to demonstrate that the university can play a more significant role in space research. 麻豆精品 S�

The project is a collaboration between UCF, the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado, and the commercial satellite company SES Government Solutions. UCF will oversee the project and build the data center that will collect, process and distribute the data for the mission. LASP will build the compact instrument, which will operate in a geostationary orbit, and SES is scheduled to launch it on one of its communication satellites in 2017.

麻豆精品 S淚t 麻豆精品 S檚 clear that NASA is interested in flying more instruments on commercial satellites, 麻豆精品 S� Eastes said. 麻豆精品 S淲ith today 麻豆精品 S檚 budgets, most science missions that need a geostationary orbit aren 麻豆精品 S檛 affordable unless they fly on a commercial satellite. 麻豆精品 S�

GOLD 麻豆精品 S檚 collaborative approach may lead the way for similar projects at UCF and other universities nationwide.

麻豆精品 S淏uilding upon the success of the Commercially Hosted Infrared Payload and innovative partnerships like the one we have with GOLD, we are extremely eager to blaze a new trail providing low-cost and timely opportunities for small- to medium-sized science payloads, 麻豆精品 S� said Rich Pang, senior director for hosted payloads at SES Government Solutions.聽 麻豆精品 S淭he selection of GOLD by NASA is a testament to the importance of the mission and the hard work and innovation of the entire GOLD team.聽聽We are excited and proud to be selected as a mission partner. 麻豆精品 S�

The scientific goals of the GOLD mission are to determine how geomagnetic storms alter the temperature and composition of Earth 麻豆精品 S檚 atmosphere; analyze the global response of the thermosphere to extreme ultraviolet variability; investigate the significance of atmospheric waves and tides propagating below the thermosphere; and resolve how the structure of the equatorial ionosphere influences the formation and evolution of plasma-density irregularities. The thermosphere is the part of the atmosphere that begins about 50 miles above the earth 麻豆精品 S檚 surface and extends to outer space.

Given the sophistication of the measurements needed, Eastes and his team turned to LASP to build the GOLD instrumentation. The lab has an international reputation for excellence and has been around since before NASA was formed.

Scientists at LASP are eager to start.

麻豆精品 S淕OLD 麻豆精品 S檚 imaging represents a new paradigm for observing the boundary between Earth and space, 麻豆精品 S� said Bill McClintock, senior research scientist at LASP working on the project. 麻豆精品 S淚t will revolutionize our understanding of how the sun and the space environment affect our upper atmosphere. 麻豆精品 S�

The five-year project will begin immediately. Once the design is finished and checked, rechecked and rechecked again, LASP will begin construction. After launch in 2017 the instruments will provide data to the team, and other scientists throughout the world, for at least two years. Eastes says the instruments will likely continue to function for an additional three to five years.

Other members of the GOLD team that will be supporting the mission include the National Center for Atmospheric Research, the University of California at Berkeley, Computational Physics Inc. and the National Oceanic and Atmospheric Administration.

The selection fulfills the dream of two UCF scientists who have been researching solar weather 麻豆精品 S� and its affects on our terrestrial technology 麻豆精品 S� for more than five years.

If chosen, this project would be the first time UCF would lead a NASA science mission.

麻豆精品 S淭here were some excited shouts from the team members this morning when I shared the news, 麻豆精品 S� said Richard Eastes, the project 麻豆精品 S檚 lead scientist and an assistant professor. 麻豆精品 S淚 麻豆精品 S檓 not used to hearing shouts from scientists. This is very rewarding. It 麻豆精品 S檚 confirmation that some of the best scientists in the world think that our mission is at the forefront of science in the field. 麻豆精品 S�

Eastes, along with his colleague Andrey Krywonos, have designed a specialized instrument that would help predict and prevent GPS and cell phone blackouts related to solar weather.

Today 麻豆精品 S檚 announcement means that UCF 麻豆精品 S檚 team was one of five selected from 20 proposals to receive $250,000 toward its work. The team would then present its concept study to NASA, vying for $55 million to develop a launch-ready project by 2016.

NASA is interested in the project because the data collected would be first of its kind, and it would help explain how earth 麻豆精品 S檚 space environment responds to the sun 麻豆精品 S檚 activities, such as solar flares.

Solar flares change the composition and temperature of the atmosphere around the earth and can damage military and commercial satellites, including those that help deliver television or cell phone signals.

And because the Federal Aviation Administration is moving toward monitoring air traffic through sophisticated GPS systems, accurate forecasts of space weather will be critical to prevent blackouts that could lead to aviation accidents.

麻豆精品 S淪pace weather can be very dramatic, 麻豆精品 S� Eastes said. 麻豆精品 S淲e just don 麻豆精品 S檛 hear a lot about it because, frankly, it 麻豆精品 S檚 in space. But it does have an impact on earth. 麻豆精品 S�

The UCF team 麻豆精品 S檚 specially designed imager, the Global-Scale Observations of the Limb and Disk — or GOLD for short — will record images of ultraviolet light emitted by the atmosphere about 62 miles above the earth 麻豆精品 S檚 surface.

Measurements will be made from a satellite orbiting in sync with Earth, meaning data can be continuously collected across the same, complete hemisphere throughout the day.The data will give scientists a clear picture of how the temperature and composition in the uppermost portions of the atmosphere respond to various influences, such as changes in the sun 麻豆精品 S檚 behavior.

Eastes and Krywonos, who conduct research at UCF 麻豆精品 S檚 Florida Space Institute at Kennedy Space Center, have been working on the project since 2005.

NASA 麻豆精品 S檚 Explorers program aims to provide frequent flight opportunities for scientific investigations from space.

These investigations have led to important information in the past, including knowledge about Earth 麻豆精品 S檚 magnetosphere and the shape of its gravity field; the solar wind; and properties of micrometeoroids raining down on Earth, among other discoveries.

Eastes joined UCF in 2001. He has master 麻豆精品 S檚 and doctoral degrees in Physics from Johns Hopkins University, home of the Space Telescope Science Institute. Before coming to UCF, Eastes worked at the Air Force Research Laboratory.

Krywonos received his Ph.D. in Optics from UCF in 2006.聽 He joined the Florida Space Institute that year as a post-doctoral researcher, and he is currently a research scientist at the Florida Space Institute.
