Son Doong Cave
Located in the limestone mountains of Phong Nha - Ke Bang National Park. Son Doong Cave was first found in 1991 by Ho Khanh, a local man. In 2009, the cave was explored and published by a group of scientists from British Cave Research Association.
Son Doong Cave was formed from 2 to 5 million years ago, when the river flowed through the limestone mountain area and was buried. The water eroded limestone and created an underground tunnel. In soft limestone areas, the collapse of tunnel ceiling formed large holes which became giant domes afterward. The cave is about 200m high, 200m wide and at least 8 5km long. Especially, Son Doong consists of two entrances, which is unique among explored caves in Phong Nha - Ke Bang National Park. Exploring the cave, visitors were surprised with spectacular scenery of numerous stalactites of which some giant stalagmites are more than 70 metres high. Deep inside the cave exists a grandiose tropical jungle called “Garden of Eden" by the explorers. The jungle is home to a diversifiedsystem of fauna and flora. Besides, the cave possesses a 2.5-kilometre underground river. Not far from the “Garden of Eden” lies an enormous “pearl collection” consisting of tens of thousands of small stone pieces in dry ponds, contributing to magnificent beauty of the cave.

The Shuttle Era Comes to an End
The set of Space Shuttle missions run by NASA captivated the world and proved that reusable spacecraft could be used to bring astronauts and cargo into space. The Space Shuttle programme had a total of six separate orbiters, five of which actually went into space. The first-made orbiter was only used to gather data about how the shuttles would glide back to the earth. This shuttle would be brought up into the air by a specially modified Boeing 747 and released to glide down without any power of its own.
The Space Shuttle Era ran from the first launch on April 12, 1981, and ended when the final shuttle landed on July 21, 2011. During this time, there were 135 missions flown. Of the five shuttles that did go into space, two met with disasters that killed all the crew members aboard.The first disaster happened on January 28, 1986 when Space Shuttle Challenger ran into severe problems and exploded less than two minutes after take-off. It was a major blow to NASA as a school teacher was on board the orbiter, and the launch was being watched by children from schools across the United States. The second disaster came on February 1, 2003. After having completed its mission, Space Shuttle Columbia was returning to the earth from space. During damage done to a wing during its launch, the orbiter disintegrated as it hit the earth’s atmosphere during re-entry.
Because the Space Shuttle programme was running, it largely made possible the construction of the International Space Station (ISS). The shuttles brought astronauts to the station, replenished supplies, and carried actual pieces to the Space Station up from the earth.As the Space Shuttle Era came to an end, many space lovers have been left wondering, “What’s next?” There is still plenty to explore, so we will all just have to wait and see.
