Which Parts of Mars are the Safest From Cosmic Radiation?
In the coming decade, NASA and China plan to send the first crewed missions to Mars. This will consist of both agencies sending spacecraft in 2033, 2035, 2037, and every 26 months after that to coincide with Mars being in “Opposition” (i.e., when Earth and Mars are closest in their orbits). The long-term aim of these programs is to establish a base on Mars that will serve as a hub that accommodates future missions, though the Chinese have stated that they intend for their base to be a permanent one.

Space Lettuce Could Reduce Astronaut Bone Loss
All kinds of challenges will face the first humans to travel to Mars. One that has been much discussed, with no potential solution yet, is the potential for a significant amount of bone density loss on the three-year mission. Astronauts lose about 1% of their bone density per month in the microgravity of the ISS. That’s not too big of a deal if they are only on the station for six months, but the two 10-month space trips of a mission to the red planet could be a concern. Now a team of researchers think they have a solution – have the astronauts eat more salad.
China is Building an Asteroid Deflection Mission of its own, due for Launch in 2025
There’s an old joke that the dinosaurs are only extinct because they didn’t develop a space agency. The implication, of course, is that unlike our reptilian ancestors, we humans might be able to save ourselves from an impending asteroid strike on Earth, given our six-and-a-half decades of spaceflight experience. But the fact is that while we have achieved amazing things since Sputnik kicked off the space age in 1957, very little effort thus far has gone into developing asteroid deflection technologies. We are woefully inexperienced in this arena, and aside from our Hollywood dramatizations of it, we’ve never yet put our capabilities to the test. But that’s about to change.
