The New Horizons probe discovers frozen plains on Pluto



After discovering high mountains, Nasa has released huge frozen plains pictures on Pluto, taken when flying over the dwarf planet by the New Horizons probe.

Among the new data released Friday, NASA was interested in a large icy plain in “Tombaugh Region”, the name given to the vast area in the shape of heart.

“So we do not see recent impact craters and the surface of this area is relatively recent, less than 100 million years. It is probably still being shaped by a geological process,” said the one of the mission scientists.

“The discovery of this vast plain young enough without impact craters on Pluto exceeds all our expectations,” he added, while scientists expected to discover otherwise.

The atmosphere escapes

Another discovery, the researchers found that Pluto’s atmosphere, composed primarily of nitrogen, escapes the dwarf planet, because of its low gravity, at a fairly significant rate “of about 500 tons per hour.”

Teams of NASA had closely observed fairly high mountains, about 3500 meters above sea level on the photos sent Wednesday by New Horizons. This should gradually send all the data collected during its Tuesday overflight within 16 months.
