NASA has $700 million to spend on a Mars spacecraft
Perspective:

A consequential debate that has been simmering behind closed doors at NASA Headquarters in Washington, DC, must soon come to a head. It concerns the selection of the next spacecraft the agency will fly to Mars, and it could set the tone for the next decade of exploration of the red planet.
An old jeweler’s trick could change nuclear timekeeping
Perspective:
Dr. Rowan Hale
A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By electroplating thorium onto steel, they achieved the same results as years of work with delicate crystals — but far more efficiently. These clocks could be vastly more precise than current atomic clocks and work where GPS fails, from deep space to underwater submarines. The advance could transform navigation, communications, and fundamental physics research.
