Organization: Travelers in The Night

Description: Today’s two stroy:
- The plants that Mars explorers take with them will provide a source of fresh fruits and vegetables, fresh air to breathe, and perhaps a psychological benefit that is crucial to the success of their mission.
- Recently there were four fireball meteors, brighter than the planet Venus, which exploded over Germany, France, Ohio, and Arizona within the space of only 10 hours. There are likely to be on the order of 1,000 fireball events over the Earth every day.
