NASA's New Horizons hover over a distant object at 6,430 million kilometers from the Sun, trip out Pluto, and scientific expectation is maximal.
Another twist in space occurred on Monday night, more than 100 million kilometers from Earth. NASA has put the ship into the orbit of the asteroid Bennu with a diameter of only 500 meters. He will draw a sample from the country and return home in 2023.
At the beginning of this year, China will reach where no-one has arrived, on the hidden side of the moon. They will look samples deeper than 100 meters.
For scientists, these journeys in the unknown are something epic, representing a spirit of adventure and discovery inherent in the human spirit.
