The electrical short plaguing the Curiosity rover has been traced to its robot arm.

Planetary Defense
The U. N. has established two organizations to deal with planetary defense. One will try to identify potentially dangerous asteroids, and the other will develop plans for dealing with the aftermath of an asteroid strike.
The next step is to develop ways to deflect asteroids aimed at Earth.

Amateur Astronomy
Amateur astronomers have always played a role in advancing the science, and that tradition continues.
Plumes high in the atmosphere of Mars, which professional astronomers haven't been able to explain, were discovered by Wayne Jaeschke, a patent attorney, and confirmed by other amateurs. Professional astronomers indeed will depend on amateurs to monitor Mars for more plumes.

Owning Asteroids
Property rights beyond Earth may well become a big issue in the years dead ahead. Asteroids, for example, are rich in scientific information-- and in economically valuable natural resources. Some legal scholars argue current space law can be interpreted to allow for property rights in space, but other scholars could argue differently.
A new treaty for a new era may ultimately be necessary.

Russia And ISS
Russia recently announced it will stay with ISS until 2024, after which it plans to build its own space station.
The U. S. has also committed to ISS until at least 2024 and hopes private space stations will take over from ISS.

Another Leak
There was another spacesuit leak during an ISS spacewalk this weekend. NASA engineers say the water came from condensation within the suit.
This is something NASA simply has to get right.
