A still mysterious solar system
Whether or not a Planet X exists, the puzzle, like a good mystery, delights the mind. But better than any novel, the puzzle’s solution has the potential to reveal something new and unexpected about our solar system.
- Planetary Science
A distant planet may lurk far beyond Neptune
Strange orbits in the Kuiper belt revive talk of a Planet X in the solar system.
- Psychology
Rigors of Mars trip make teamwork a priority
It’s going to take a different kind of mental approach to travel to Mars and back: less individuality, more collaboration and adaptability. Astronauts are being tested to prepare for such a mission.
