What did Mars look like 4 billion years ago? The team at NASA’s Conceptual Image Lab have an idea based on the existing evidence:
Billions of years ago when the Red Planet was young, it appears to have had a thick atmosphere that was warm enough to support oceans of liquid water - a critical ingredient for life. The animation shows how the surface of Mars might have appeared during this ancient clement period, beginning with a flyover of a Martian lake. The artist’s concept is based on evidence that Mars was once very different. Rapidly moving clouds suggest the passage of time, and the shift from a warm and wet to a cold and dry climate is shown as the animation progresses. The lakes dry up, while the atmosphere gradually transitions from Earthlike blue skies to the dusty pink and tan hues seen on Mars today.
The animation was released in anticipation of November 18th’s Cape Canaveral launch of MAVEN, Mars Atmosphere and Volatile Evolution mission. MAVEN will explore the planet’s lost atmosphere.

Watch Lord Paul Drayson, former Science Minister, science entrepreneur, and owner of Drayson Racing Technologies, set a new world land speed record for lightweight electric vehicles after achieving an average of 204.185mph in a lithium-nanophosphate battery-powered car. From The Guardian:
It was a demonstration of a technology that is slowly keeping its promise to revolutionise the way we travel. And for the first time in half a century, motor sport seems to be showing itself capable of making a significant contribution towards accelerating the development of that technology.
"I really think that the changes that are taking place in the car industry need to be reflected in motor sport," Drayson said shortly before setting off on his record-breaking run.
"We’re seeing this huge shift to the electric drivetrain in the mainstream industry, so motor sport has got to pioneer this technology, too. It’s got to lead on the innovations and help reset people’s expectations about what an electric car can do."
There are more vehicles, more electricity videos, and more world records in the archives.
