Chandrayaan's M3 Looks Back At Earth

[/caption] It's a little fuzzy, but considering the camera was meant to capture the surface of the Moon from 200 kilometers (124 miles) away rather than Earth at 360,000 km (224,000 miles), it's not bad. This image was taken by NASA's Moon Mineralogy Mapper (M3 - M Cubed), on board the Indian Space Research Organization's Chandrayaan-1 spacecraft orbiting the Moon. Australia is visible in the lower center of the image. The image is presented as a false-color composite with oceans a dark blue, clouds white, and vegetation an enhanced green. The image data were acquired on July 22, 2009.

The Moon Mineralogy Mapper instrument is a state-of-the-art imaging spectrometer designed to provide the first map of the entire lunar surface at high spatial and spectral resolution. Scientists will use this information to answer questions about the moon's origin and development and the evolution of terrestrial planets in the early solar system. Future astronauts will use it to locate resources, possibly including water, that can support exploration of the moon and beyond.

Taking an image of Earth, well, that's just showing off!

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
