The Martian.


 The story was about a group of astronauts, Ares 3 doing their expedition on Mars but while on working the heavy storm attacked them. They made a decision to leave Mars but unfortunately, Mark Watney was hit by broken antenna in the storm and he lost from their sight and his suit was detected breached. They left him behind as they assumed he was dead because lost of oxygen. On Earth, NASA claimed that members of Ares 3 were saved but not Watney. But luckily, Watney was alive and he was heading back to the HAB and treating his injury by himself. Watney had no way to contact NASA and started to think about the obstacles he might faced on Mars. He began to record about his survival on Mars. He was a botany, so he planted all the potatoes in the HAB to increase his food sources by using Mars' dirts and his friends' wastes as fertilizer. As he realized about the water shortage, he began with an idea which was he took the hydrogen and oxygen and burned it. By using hydrazine from MDV, he ran it over iridium catalyst to seperate the N2 and H2, then directed the hydrogen into small area and burned it. He failed at first, but the second trial he did it. At the Mission Control, Mindy Park discovered that the Acidalia Planitia was different in between Sol 18 to Sol 54. From that, they knew that Watney was still alive. Watney did not use the heater as he wanted to save up the solar battery from the Rover 1, so he used the decaying radioactive isotope as heater in the Rover 1. He figured out how to communicate with NASA by using the pathfinder. He used the hexadecimal to talk to them. It was a success and NASA taught him on how to hack the pathfinder to the Rover 1 to make the communication better and easier. NASA told him that they would rescued him. The probe was launch in very short days, to save Watney from dying on Mars but it was not a success as it exploded after the launching because the inspected was not done properly. As they lost hope, Rich Purnell the astrodynamics proposed his ideas to NASA on how to get the Hermes to Mars by using Taiyang Shen. Ares 3 came to the rescue. Watney accelerated towards the intercept but the distance was far and the velocity was way down below than what they had expected so they needed to increase their Hermes' velocity to reach Watney. They used atmosphere as thrust by using bomb that made up of sugar and liquid oxygen. Watney poked his suit and used the escaping air to fly like an 'ironman' from the MAV to Johannsen. Watney was saved and returned to the Earth. It was a nice  and emotionally movie that should be watched.
