THIS WEEK IN SCIENCE

Here's a quick rundown of this week in science . . .

  

1. The Mars helicopter finally kicked the bucket. NASA announced one of its rotor blades got damaged, so it can't fly anymore. In just under three years, it made 72 total flights. It was only supposed to make five.

  

2. In other space news: Scientists tested a new inflatable space station, and intentionally pumped it up too much until it exploded . . .
