First image of earth from Indias Mars Orbiter Mission

India’s first mission to Mars, the Mars Orbiter (Mangalyaan) crossed the distance of the moon’s orbit this morning, making it the farthest object sent into space by India. A few days ago, the spacecraft looked back, and sent a postcard back home. This is the first image of Earth taken by the Mars Color Camera (MCC) aboard the Mars Orbiter Spacecraft. The image was taken on November 19, from an altitude of 67975 kilometers.

Prepare yourself for new royalty shaped in the form of mice. But that’s not just any mice, these are mice with the DNA of the king of rock and roll. For his “All That I Am” project, Koby Barhad used the DNA of Elvis Presley in genetically engineered mice. The idea is to explore ethical and philosophical concerns, ranging from questions of talent, to the ownership and legal rights tied to using someone else’s genetic data.
