Satellite Captures Solar Eclipse from Space

[/caption] The recently launched Proba-2 satellite was able to observe the annular solar eclipse on January 15, 2010, with stunning results. The PRoject for OnBoard Autonomy satellite was launched on November 2, 2009 and is intended to test hardware and software that might be incorporated into future ESA missions. The eclipse offered a unique chance to test out the Sun-imaging instrument, SWAP (Sun Watcher using APS detectors and imaging processing). Another radiometer instrument was also able to take measurements during the eclipse.

Proba-2 is one of the smallest satellites launched. The 0.6m by 0.6m by 0.8m satellite contains several instruments, a computer, battery, thrusters, and solar panel systems.

The eclipse was also detected by the Proba-2's LYRA (Lyman Alpha Radiometer) instrument, the first ultraviolet radiometer in space that employs diamond detectors. LYRA will measure solar flares with an unprecedented rapid time resolution of 0.5 sec. LYRA data will soon be feeding research investigations and space weather forecasts.

Proba-2 was a secondary payload included on the launch of the SMOS mission, the Soil Moisture and Ocean Salinity Earth Explorer.

She is currently retired from daily writing, but worked at Universe Today for 20 years as a writer and editor. She also contributed articles to The Planetary Society, Ad Astra (National Space Society), New Scientist and many other online outlets.

Her 2019 book, "Eight Years to the Moon: The History of the Apollo Missions,” shares the untold stories of engineers and scientists who worked behind the scenes to make the Apollo program so successful, despite the daunting odds against it. Her first book “Incredible Stories From Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos” (2016) tells the stories of 37 scientists and engineers that work on several current NASA robotic missions to explore the solar system and beyond.

Nancy is also a NASA/JPL Solar System Ambassador, and through this program, she has the opportunity to share her passion of space and astronomy with children and adults through presentations and programs. Nancy's personal website is nancyatkinson.com
