Mars Missions Ahead for U.S. (and Russia?)

A Russian space probe headed for Mars' moon Phobos has stalled in Earth's orbit. Meanwhile, N.A.S.A. plans to launch its biggest Mars rover yet in just over two weeks.

What's the Latest Development?

The Russian space probe headed for Mars' moon Phobos has stalled in Earth's orbit after one of its rockets failed to fire. The Russian space agency has three days to reorient the craft before it loses battery power. The failure is another in a long list of mishaps that have cursed Russia's ambitions to explore Mars and its satellites. In fact, not one of 18 Soviet and Russian missions sent to the Red Planet has been fully successful. Within the next two weeks, the U.S. will launch another rover to explore the Martian surface, its biggest one to date.

What's the Big Idea?

If the Russian mission to Phobos fails, it will be a great loss. Besides collecting soil samples, the probe is carrying ten of Earth's most hearty and resistant bacteria. The experiment is called L.I.F.E. (Living Interplanetary Flight Experiment) and was designed to determine if especially resistant life forms can endure the cold vacuum of space long enough to travel to another planet. If successful, it might help us understand whether life came to Earth from another source or if life from our planet might have traveled elsewhere.

A bionic lens undergoing clinical trials could soon give you superhuman abilities

We're talking Ghost in the Shell type of stuff. 


Maybe you watched Ghost in the Shell and maybe afterwards you and your friend had a conversation about whether or not you would opt in for some bionic upgrades if that was possible - like a liver that could let you drink unlimitedly or an eye that could give you superhuman vision. And maybe you had differing opinions but you concluded that it's irrelevant because the time to make such choices is far in the future. Well, it turns out, it's two years away.

Surprising Science
  • A forensic artist in Scotland has made a hyper realistic model of an ancient dog.
  • It was based on the skull of a dog dug up in Orkney, Scotland, which lived and died 4,000 years ago.
  • The model gives us a glimpse of some of the first dogs humans befriended.
