Astronomers Has Discovered Ghost Dunes on Mars

Astronomers found out ghost dunes on Mars, they have acquired images of ghost dunes which is tall crescent-shaped sand dunes once existed on this red planet. As we know, Mars is a desert planet, and it is more like Earth than any other planet, but it is colder there than on Earth. Also just like Earth, the Martian deserts have massive dunes. Astronomers informed the finding in GeoSpace on July 10, 2018. The new research paper was just published in the Journal of Geophysical Research.

Why NASA Wants to Send Marsbee Robotic Bees to Mars

Why NASA Wants to Send Marsbee Robotic Bees to Mars?

Marsbee is a robotic flapping wing flyers. Its size is as the same as bumblebee size with cicada sized wings. The Marsbee is combined with sensors and wireless communication devices.  The mobile base can act as a recharging station and main communication center. Why NASA wants to send Marsbee to the Red Planet. NASA explains:

“The objective of the proposed work is to increase the set of possible exploration and science missions on Mars by investigating the feasibility of flapping wing aerospace architectures in a Martian environment. The proposed architecture consists of a Mars rover that serves as a mobile base and a swarm of Marsbees.”
