Flyover Video of Ceres Shows the Grandeur of Space Exploration

Wow. This video will knock your socks off ... at least it did mine. This new flyover video of Ceres was created using enhanced images taken by the Dawn spacecraft's framing camera. It was produced by the camera team at the German Aerospace Center, DLR, using images from Dawn's high-altitude mapping orbit of 900 miles (1,450 kilometers) above Ceres' surface. The video shows a stark and stunning world.

"The viewer can observe the sheer walls of the crater Occator, and also Dantu and Yalode, where the craters are a lot flatter," said Ralf Jaumann, a Dawn mission scientist at DLR.

The enhanced color used here helps to highlight subtle differences in the appearance of surface materials. There's additional info at the end of the video, but for a quick reference, area with shades of blue contain younger, fresher material such as flows, pits and cracks, while brown areas clays, which, enticingly, usually form in the presence of water.

I had the chance to visit with Marc Rayman, Dawn's chief engineer and mission director at JPL earlier this month, when I interviewed him for a book I'm working on about robotic space exploration. One thing he really stressed is that Ceres is a

big

place, with diverse terrain and a variety of features. This video really brings that home.

"Ceres has a surface area of 2,770,000 square kilometers ... It's a big surface and we haven't seen all of it," Rayman said. "It will be great to see what the new detail shows from the low altitude orbit, because those pictures will be four times better resolution than pictures we were able to get at our previous orbit."

Dawn is now in its final and lowest mapping orbit, at about 240 miles (385 kilometers) from the surface.

This animated flight over Ceres emphasizes the most prominent craters, such as Occator, Dantu, and the tall, conical mountain Ahuna Mons.

The bright features seen in Occator Crater have been determined to be salts, which are quite reflective and look bright to our eyes (sorry no alien city lights) and the team will be providing more details and images soon.

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
