INTRODUCTION
In the year 1999, NASA lost its two major missions to Mars. Mars Climate Orbiter (MCO) and Mars Polar Lander (MPL) were part of a bigger project Mars Surveyor Program (MSP) that began in 1994. Mars Global Surveyor (MGS) was the first part of this project, launched in 1996 and ended in January 2007. This report discusses the Mars Polar Lander with two Deep Space 2 probes, on board with MPL, and the most probable causes that may have led to MPL failure.
BRIEF HISTORY
Mars Surveyor Program of NASA started in 1994, supposed to send spacecraft to the Red Planet every 26 months. The first spacecraft, MGS was a success, launched on November 7, 1996 and arriving on September 11, 1997. Before going silent in November 2006, it provided

To study the surface environment, weather and geology, MPL carried the Mars Volatiles and Climate Surveyor (MVACS). MVACS was an integrated package consisting of surface stereo imager, a 2-meter robotic arm with a digging scoop, camera and temperature probe and a meteorology pack. MPL was supposed to dig into surface and collect a soil sample with its robotic arm and then heat them up and analyze for content of volatiles using a thermal and evolved gas analyzer. The meteorological package would have taken temperature and pressure reading from Martian morning until afternoon2. The Mars Descent Imager (MARDI) was designed to take pictures as MPL descends to the surface starting from heat-shield ejection until landing. It also carried a Russian-provided Lidar instrument and a small microphone from the Planetary Society. The task of Lidar instrument was to describe ice and hazes in the atmosphere. MPL had two radio systems, one in UHF band for communication with MCO, but this plan was cancelled after failure of MCO and second in X-band for direct communication with …show more content…
When cruise lander separates from cruise stage, then these microprobes would be released and have powered up themselves from lithium batteries. Probes were in aeroshell, which upon falling on the surface would be destroyed by the impact and probes would be released to surface almost 60 miles away from the Lander’s site. Then probes would be separated into two parts, one will remain on surface and other will be penetrate into the surface by as much as meter. These were connected by cable. The purpose of penetrator was to collect soil samples and heat them up to detect water vapor and measure soil conductivity. Then this data will be passed to aft-body (part of probe on surface) which would transmit this data to MGS and then to Earth. DS2 mission was 2 days with main objective to test new technologies for future projects as its landing was lightweight, launched with Lander, and it was the first penetrator sent to other
3. X-Band/Ground-Based Radars: These radar systems gather tracking information regarding the incoming warheads during the mid-course phase of the missile. This data is then sent to the BM/C2, which in turn is sent to the GBI for guidance to intercept the warhead.
The story of The Martian focuses on the obstacles botanist and astronaut Mark Watney must overcome to survive on the planet Mars. His adventure is filled with fictional and non-fictional elements that are most likely difficult for the normal individual to identify what is actually realistic and what is simply fantasy. After taking a closer look, this film contains a lot more realism to actual science and space travel today. This paper will closely analyze and discuss three accuracies and inaccuracies of the film in relation to the content discussed in ESS 102 lectures, labs, and assignments.
The aircraft needs to use two beams to ensure that the pulses return to the aircraft. In certain situations the pulse may not return to the aircraft due to flat glassy water surface (because of the law of reflection) . The Lads software automatically compiles arrival times and fixes errors in the data like tidal variations. Maps can be made after data is compiled from the aircraft by using Global Positioning Satellites, which constructs coordinates and data collected.
The objectives of the Mariner 10 spacecraft were the foundations to influence a great scientific change in history. The primary objectives were the main reasons Mariner 10 lifted off. Measurements of environments, atmospheres, surfaces, and body characteristics were to take place (“Mariner 10” Mariner 1). Mercury’s core needed to be studied. Venus’s interaction with the solar wind and the way sun particles affected the planet needed to be explored (Howell 2). Secondary objectives included experiments being performed and the process of using the gravitational pull of one planet to reach another (“Mariner 10” Mariner 1).
Brief Descriptions of the Original Activity: After completing notes, the students watch the Mars Rover video and do questions related to the movie. We then normally do follow up worksheets with which orbiter has explored particular planets in a chart that includes the names and what was discovered. Then the students create their own rover and write a paragraph about what they would like the rover to explore. This is mostly focused on Mars because the students can then view GoogleMars and see what has been discovered with the pictures that have been released.
“All the facts about Mars are accurate, as well as the physics of space travel the story presents. I even calculated the various orbital paths involved in the story, which required me to write my own software to track constant-thrust trajectories,” Andy Weir on the scientific and mathematical attention to the book The Martian. There is no doubting Andy’s attention to detail. He used his dreams to create a story and backed it up with hard facts. Drew Goddard’s film adaptation, however, lacked a moral judgement in keeping the ending honest. He failed to incorporate the facts which Mark Watney clearly explained in the novel. Finally, the emotions towards the main character, Mark Watney, was somewhat clouded in the film. Moreover, the movie version of The Martian by Andy Weir is an unacceptable adaptation, because the conflicting purposes caused intense changes to the story.
Many important themes can be drawn from reading Roving Mars that share important lessons about the scientific process. This personal account by the author, Steven Squyres, shares his story of passion toward being able to play a hand in the exploration of mars. The account shares many valuable lessons that we can learn for the scientific process and trend that appear in most scientific discovery. The greatest theme that can be gathered from Squyres story is that Science is never easy and it may come with many failures but the most important thing to do is persevere through these challenges. Another important thing to gather from the book is that not all discovery involves proving everything right or testing everything then and there to see if
In mid March of 1998, a scientific break through occurred for the engineers at NASA. The space probe that they sent to Mars came back and, for the first time, contained readable and usable photographs of the planet's landscape. Full of pride over their latest achievement, NASA posted the information on the Internet. This allowed astronomy enthusiasts, students, and other interested individuals to take a first hand look at the, never before seen, Martian Landscape. (NASA)
“I think humans will reach Mars, and I would like to see it happen in my lifetime” was said by Buzz Aldrin, a NASA astronaut. The former American aeronaut from Montclair, New Jersey believes that since Mars does exist, it is waiting to be reached by humans. When this would happen, he says that the human race would “evolve into a two-planet species.” Present day Mars has a lot of canyons, mountains and volcanoes. Even though the surface is Mars is very old, scientists learned about different younger rift valleys, plains, hills and ridges. According to recent reports, there were lakes and rivers, along with an ocean billions of years ago. The low temperatures on the planet cause there to be polar ice caps and frozen water present. Scientists continue to notice several discoveries on the planet that lead them to think there was once life on the planet. Different clues have scientists wanting to find out about even more. Many scientists in the past few centuries have been curious if life on Mars is possible or if it has ever been before.
The Climax in The Martian takes place when pathfinder, the communication device that Mark was using in order to talk to NASA has one of its wires fried and loses its capability to transmit messages over such extreme distances. This occurred when Mark was working on the rover to prepare it for his final trip on mars to the Ares 4 site when he set a drill he was using very close to Pathfinder without noticing and the wires from the drill touched Pathfinder. Since the drill was so much more powerful than Pathfinder the amount of electricity it transmitted when the wires touched was enough to cause the wires of Pathfinder to fry. Power traveled from the drill line's positive lead, through the work bench...and
Those commands are then sent to the satellite using large antennas on the ground. The satellite later receives the commands, executes them, and it sends the information to the same antennas back to the ground. Then the scientist in the computer can read the information. When CloudSat takes the images a cloud, it will take on average about 4 hours before the satellite sends the information to the large antennas on the ground. The people who run the antennas live in Albuquerque and the ones who process it live in Colorado.
MARS CLIMATE ORBITER Anonymous Submission for Written Assignment Grading University of the People Abstract The Mars Climate Orbiter cost NASA $327.6 million when it was destroyed in Mars’ atmosphere. Reasons determined to have contributed to the failed mission, point to insufficient quality management. Specifically, teams were not effectively communicating, training was inadequate, and technology was not verified.
They are the Imager for the Mars Pathfinder, the Alpha Proton X-ray Spectrometer, and the Atmospheric Structure Instrument/Meteorology Package. The Imager took images of the Martian surface, including
I don’t know since when, but after my dream was to become a cheetah had faded out, I was a little paranoid and yearned for being a “evil mad scientist” and it was perfect, I had all the qualities that I thought they were like. People always referred to me as a creepy, freaky or crazy. Didn’t think it was that bad cause there was respect towards me with knowledge.
NASA’s planned missions to Mars, should it come to fruition, will be the furthest distance any human being has ever traversed. While this is an impressive feat in and of itself, it becomes even more so when one takes into acco...
