X-37B Orbital Test Vehicle (OTV) Orbit

X-37B Orbital Test Vehicle (OTV) Orbit X-37B ORBITAL TEST VEHICLE COMPLETES 625 DAYS IN ORBIT Wg Cdr PA Patil X-37B Orbital Test Vehicle (OTV), a spacecraft operated by the US Air Force was launched aboard the Atlas-V on December 11, 2012 and is stealthily zooming in orbit rising speculations on its clandestine nature of operations. Designed on the contours of Space Shuttle, X-37B is an unmanned spacecraft with a much smaller size fielding advanced technology in a compact airframe structure. X-37B is modified version in the series of X-37 space craft with the earlier version X-37A being used as an Approach Landing and Test Vehicle (ALTV). The USAF claims that this spacecraft is a technology demonstrator of robotic space plane aimed at validating and corroborating the endurance of reusable space vehicle technology. As on date a total of three X-37B missions have been flown. The first mission launched on April 22, 2010 spent a total of 224 days in space and this was followed up with a second mission launched on March 05, 2011 to complete 469 days in the orbit. The third mission continues to or bit in space and has spent in excess of 625 days creating a longevity record. The space craft conceived by NASA in the year 1999 was designed and developed as a reusable re-entry spacecraft by Boeing Integrated Defense System. The project in the year 2004 was transferred to Defence Advance Research Project Agency (DARPA) and was accorded a classified status by the US Air force. The X-37B is 8.9 meters in length, spans 4.5 meters in width, and is 2.9 meters tall weighing 4990 kg.[1] This mini-Space Shuttle like space plane is characterized by the likes of both an aircraft and a spacecraft has been designed for a vertical launch using an expendable launch rocket. The spacecraft is designed to operate in Low Earth Orbit (LEO) at an altitude of 175 to 800 km and is slated to operate at a nominal speed of 7.4 to 7.8 km/s at these orbital altitudes.[2] Once released into the Low Earth Orbit (LEO), the X-37B can stay in orbits for a prolonged duration spread over months. It would derive the power from a specially designed solar array and also carries lithium-ion batt eries to conserve the propellant fuel.[3] Further, it has been designed for aircraft like maneuverability in space and thus would be capable of changing speeds and the altitude or orbits. As the speed of an object irrespective of mass and size at a given altitude in space is fixed, this space plane can continue in its orbit for an indefinite period till it is commanded to change its course or position. The space craft de-orbits from space under the command from ground and would autonomously re-enter the atmosphere in a glider configuration to land horizontally on a runway. As per the latest data extracted on Aug 16, 2014, the X-37B was found to be in an elliptical orbit with a perigee of 313 km and an apogee of 327 km orbiting at the rate of 15.83 revolutions per day.[4] Further, observations of amateur satellite trackers indicate that the X-37B has made only one or two maneuvers. If these observations are true then the spacecraft would have conserved sufficient reserves of thruster propellant for future maneuverability.[5] The sustenance of X-37B in orbit for such a long duration also suggests that the spacecraft is maintaining a persistent orbital profile. The X-37B program from the very beginning has intrigued the world on the secretive nature of its mission and profiles. As per the X-37B OTV factsheet displayed on website of US Air Force, â€Å"the program is to evaluate and test technology of advance guidance, navigation and control, thermal protection systems, avionics, high temperature structures and seals, conformal reusable insulation and lightweight electromechanical flight systems†.[6] However, majority of these stated assessments involve the evaluations in the de-orbiting phase when the spacecraft will be subjected to the re-entry effects and would be required to glide for a controlled landing on the airstrip. Thus, the rationale for sustaining the spacecraft in orbit for such a prolonged duration defeats the proclamation of ‘developing and validating the reusable space vehicle technology’ by the US authorities. A space plane can be planned for numerous tasks that would include maintenance of space assets, extend logistic support for improving life cycle of satellites and space stations, carry out ISR missions, act as a platform for insertion of satellites or act as a space weapon platform. As the mission of X-37B has been closely guarded secret, a number of articles and reports have contemplated the use of this spacecraft as a space weapon platform. The payload bay of the OTV is limited by the size of 7 feet by 4 feet.[7] This size of payload bay would not be in a position to accommodate heavy and large weapon systems. While the platform could be designed to carry small automated weapon systems, the functionality of onboard weapon systems would entail additional payloads in terms of sensors and communication equipment. Further, use of X-37B as a weapon platform would not confer any kind of distinct advantage to United States as it is way ahead in space ventures when compared to its closest adversary. The probability of X-37B acting as an ISR platform is very high as the technologically advanced compact sensor systems can be suitably accommodated in its payload bay. Further, the ground track followed by the space plane is shown below in figure 1 indicates a comprehensive coverage of the middle east countries, the Chinese subcontinent and east Asian subcontinent. While, the exact mission of this space plane would be difficult to judge, the evaluation and experimentations with technology would definitely provide an edge to the United States for its future space ventures.

Whats Really Good Essay

   (1) (a) One passage from Nouwen I found particularly informative to my learning was from the middle of paragraph one of page 103. Nouwen explains, â€Å"Poverty is the inner disposition that allows us to take away our defenses and convert our enemies into friends. We can only perceive the stranger as an enemy as long as we have something to defend.† Here Nouwen is explaining that a reason for hostility is because we are afraid that others will take away what we have. This can be anything to actual tangent property, or our beliefs of what we are, such as the thought that we are the best math student. We are hesitant to help another student out because we are afraid they may threaten our belief that we are the best student. Nouwen is saying that if we become poor, as in overcome our fear of losing something, we can become great hosts of hospitality. If we are willing to give up everything we have, no longer will strangers become threats. It becomes easier to give and create an open space for our guest to be themselves, once we have invited in poverty and faced the fear of loss. Moving from hostility to hospitality is a major theme of Nouwen’s book. (b) A Christine doctrine implicit in this passage is the doctrine of original sin. Unfortunately, we all believe we can create our own reality and exist as a God in our own right. As a result of this belief we fail to recognize the dignity and commonality in all beings. Our original sin causes us to shun others out believing that we do not need them and can manage sufficiently in isolation. In reality this hurts both ourselves and others from not realizing our interdependent nature. (c) After reading this passage I began to realize how often I do this to other people. I recognized that at times out of selfishness and fear of losing everything I have worked so hard for I view other people as opponents, not as people who inherently deserve respect for being created in the image of God. I then started to ponder how I have felt or would feel if I was viewed by a stranger as enemy for no apparent reason. I discovered how horrible it is that we hold our things and beliefs over the worth and well being of or fellow individuals. It seems so foolish that we would through this. And from this recognition I realized how the marginalized can be used to promote change and growth within myself and others. (2) Loneliness, the longing for deep connection, perfect love and inner peace does give rise to illusion. Nouwen, illustrates, â€Å"It is sad to see how sometimes people suffering from loneliness, often deepened by the lack of affection in their intimate family circle, search for a final solution for their pains and look at a new friend, a new lover, or a new community with Messianic expectations† (Page 30, Par 2). Here is becomes apparent that when people are suffering from loneliness

Implementing The Network s Security - 873 Words

In the future organization need to take a proactive approach to the network s security. This strategy of safeguarding the network as well as the patient data, such as scanning and social engineering should be mandatory as opposed to best practices. As the case study shows a major breach had a drastic impact on the healthcare organization and efforts should have been made ahead of time to prevent disaster. Organizations should understand security and risk budgeting and learn how to gain support from the board level for the investment needed to protect data. The industry should push the government to include required annual Health Information Trust Alliance (HITRUST) assessments compared to the current HIPAA [7]. HITRUST is an organization developed by healthcare and IT professionals to help healthcare organizations protect patient information better than HIPAA guidelines. If government mandates shifted towards HITRUST standards the healthcare industry as a whole could benefit across t he boards and it can focus more on the patient care and less on the fear of an impending data breach. As mentioned in the previous sections these software and techniques won t 100\% prevent attacks, but they will definitely help prevent and detect attacks beforehand. section{Future of Cybersecurity} There is a growing realization that cybersecurity requires budgetary commitment, sincere collaboration, and a solid plan.

Womens Rights Through History - 1127 Words

HALAC Whitehead 3/27/11 Women’s Voices, Women’s Lives Women’s roles through history have changed and stayed the same in many different ways. Based on evidence from historical documents, â€Å"The Yellow Wallpaper† by Charlotte Gilman, â€Å"The Life You Save May Be Your Own† by Flannery O’Connor, â€Å"Raising A Son - With Men on the Fringes† by Robyn Marks, â€Å"Self in 1958† by Anne Sexton and modern day examples as well. Overall, since 1880, women’s rights have been a controversial topic based on their power, roles and societal expectations to a very interesting extent. First, a strong example of women’s roles in the late 1800’s is represented in the document â€Å"The Husband Commandments† by H. De Marsan. It gives a fairly accurate portrayal of how†¦show more content†¦The ‘noise’ referring to the loud commands from her husband not giving her freedom at all. The woman is living a life that is sm all and has limited possibilities. Additionally, Raising A Son - With Men on the Fringes by Robyn Marks, Is a portrayal of how the average woman is supposed to raise her children and be expected to maintain the expected behavior that women have. It also shows how women’s roles have changed and that men can be on the ‘fringes’ and get away with it. However if the woman in this story wanted to act like the man, it would have been looked down upon and since she was a black woman she was facing many more struggles then a white single mother would. This reveals how women can’t back out of their responsibilities and have more pressure. On the other hand, in the modern day, women‘s roles are very superficial and based on the perfect image. An example of this is based on â€Å"Seventeen† magazine’s January 2009 issue, it displays the perfect figure by a picture of Beyonce. It has big labels saying ‘Pretty Looks for You’ and ‘ Get Your Best Body’. This shows that today in the modern day women are just basically expected to have the perfect body and looks. Another example would be in the magazine â€Å"Mother Baby,† there is always a picture of the mother and baby and very rarely the father is mentioned in these magazines.
