Orbit change of artificial satellite

In order to raise the altitude of an artificial satellite, it is necessary to accelerate it. When the orbital speed increases, the centrifugal force generated by the rotation of the satellite becomes stronger than the gravity of the earth applied to it, then the altitude rises. At this time, a certain amount of energy is returned from the satellite to the vacuum space to reduce the energy debt. Hence the orbital speed decreases and finally drops below the initial speed. The sum of the reduced amount of the momentum energy and the energy required for the acceleration is returned to the vacuum space.

In order to lower the altitude of an artificial satellite, it is necessary to decelerate it. When the orbital speed decreases, the centrifugal force becomes weaker than the gravity, then the altitude drops. At this time, the satellite is given a certain amount of energy from the vacuum space. Hence the orbital speed increases and finally rises above the initial speed. The sum of the increased amount of the momentum energy and the energy released by the deceleration is borrowed from the vacuum space.

Whilst exploring the deserts of Nevada, avid hiker Kenny Veach came across what he described as an “M shaped Cave”. 47-year-old Veach was so excited about the discovery, that he wrote a lengthy YouTube comment on a video titled “Son of Area 51 Technician”, detailing his experience. Using the screen name SnakeBitMgee, Kenny explains how his “whole body began to vibrate” and that he got so scared, he decided to “hightail it out of there.” Kenny’s comment became viral, with other users encouraging him to go back there to explore the mystery of this unusual M shaped cave, so he did. Armed with a 9mm handgun and a video camera, Kenny explored the cave and uploaded this youtube video. 

The video is over 20 minutes long and it shows a happy looking Kenny exploring the location where he found the cave. To his dismay, the mystery cave is gone. His video was met with criticism from his disappointed subscribers, and it seemed as though Kenny was just faking the whole thing. However, one comment was particularly ominous, as it foretold Kenny’s fate. It read: “No! Do not go back there. If you find that cave entrance, don’t go in, you won’t get out.”

Ultimately, that is exactly what happened. Or so we think. On November 10th, 2014, Kenny set out for his last hike. He told his girlfriend that he would be staying out overnight and would return the next morning. He never did. Kenny Veach was reported missing, and an extensive search commenced. A few days after he vanished, Kenny’s cell phone was found by the old mine-shaft featured on his YouTube video. After that, the trail goes cold. 

There have been no sightings, nor any shred of forensic evidence that might give Kenny’s loved ones some hope. Could he have fallen to his death down there? That may be the case, although another theory suggests that he got lost in the newly discovered M shaped cave. Kenny was an experienced spelunker and hiker, but even experts can run into difficulty and perhaps mortal peril. To this day, neither Kenny Veach nor the M shaped cave have been found. Some people believe that he stumbled upon a secret entrance to Area 51, others think he succumbed to the elements. Whatever the truth, Kenny’s disappearance remains a frustrating mystery.

This is the Mesha Stele. Written around 850 BCE, it was commissioned by King Mesha of Moab, a small nation around what is today Jordan. The basalt stele describes how Chemosh, the god of Moab, had previously been angry with his people and had allowed them to be subjugated to Israel but he eventually returned to his people and helped them gain their freedom from Israel. The stone then details King Mesha’s building projects.

The Mesha Stele roughly agrees with the Israelites version of events in the Books of Kings (2 Kings 3:4–8). Which makes it really, really important historically. The stele is also the most extensive inscription ever recovered that refers to the kingdom of Israel and it bears the earliest certain reference to the Israelite god Yahweh outside of the Bible itself.
