INTRODUCTION The AprizeSat spacecraft, built, owned, and operated by SpaceQuest, Ltd. are part of a constellation of micro- satellites with a primary Machine-to-Machine (M2M) mission. On 29 July 2009, SpaceQuest launched AprizeSat-3 (AS3) and AprizeSat-4 (AS4). Both spacecraft continue to perform their M2M and AIS missions in their sun-synchronous orbits. Design, integration, and testing of the next generation AprizeSat spacecraft began in September 2008. From then, SpaceQuest followed its characteristic rapid development process to produce three operational spacecraft – AprizeSat 5 is retained as a software test- bed and flight spare. AS3 and AS4 were launched into a sun-synchronous, 10:30 orbit aboard a Dnepr rocket (converted SS-18 Russian ICBM) by ISC Kosmotras. Automated commissioning of the spacecraft was accomplished in the first two orbits, even before contacting the ground station for the first time. MISSION The AprizeSat spacecraft have a dual-purpose mission: AIS and M2M. Both missions can be performed in tandem, without interfering with the other. The AIS mission has received the most attention since launch due to the payload’s unique capability to resolve message collisions and decode numerous ship radio transmissions in the same frequency channels. Machine-to-Machine – M2M The AprizeSat spacecraft are equipped with low-power UHF receivers and transmitters that communicate with ground-based asset-tracking “Tags.” The tags include a microprocessor, UHF transceiver, sensor interface, and long life battery. Various sensors inputs and/or outputs are integrated depending on the application, and an integrated GPS receiver is optional. an Earth station where signal analysis proved that A... ... middle of paper ... ...was pinched under a standoff. The harness was replaced and the GPS receiver was re- integrated to the tray. Testing showed that the GPS was now functioning well and the problem was resolved. The spacecraft was re-integrated and tested to show that no other systems had been compromised by the diagnostic activities. From detection of the problem, through the remedy and confirmation of a once-again- healthy spacecraft, the process took approximately 3 hours and the spacecraft was ready to be transported to the launch site in the morning. Mission Timeline Table 1 delineates the 10-month timeline of the recent AprizeSat mission from conception to launch. Though short and responsive, this AprizeSat program was actually longer than previous AprizeSat programs by several months, which is attributable to added design complexity and other on-going projects.

The U.S. Army Space and Missile Defense Command is working on a new active defense weapon system concept to enhance protection for combat forces and theater-level assets for the Force XXI Army. The mobile Tactical High Energy Laser, or THEL, weapon system would provide an innovative solution for the acquisition and close-in engagement problems associated with "dumb munitions" — a primary concern because counter-battery fire may not be an option in densely populated areas.
NSSS states a few current trends in space as being “congested and contested” (NSSS, 8), which is shaping our space strategic environment as well as fueling debates for space weapons. “Congested” trend refers to the current “60 nations and government consortia that own and operate satellites and the expectation to have 9000 satellite communication transponders in orbit by 2015.
Hubble is a telescope used by NASA as one of the orbiting "great observatories”. Hubble was launched in 1990, changing the history of astronomy since Galileo's telescope with an expected lifespan of 15 years, although will really be about 22 now. Early on, Hubble was used to discover galaxies beyond the Milky Way. The purpose of the Hubble Telescope is to gather light from cosmic objects so scientists can have a better understanding of the universe around us. Hubble is one of the best telescopes to ever orbit the earth. It was one of the very first telescope to be placed in space. The purpose of Hubble is to take pictures of the galaxy as it orbits around the Earth at 17,500 mph. These images are very detailed because the Hubble Space Telescope orbits around the outer atmosphere. Even though weight is not an issue in space, Hubble weighs 24,500 pounds. Many different instruments are used by Hubble, including the Cosmic Origins Spectrograph. Originally installed in May 2009, the Cosmic Origins Spectrograph replaced the Corrective Optics Space Telescope Axial Replacement (COSTAR), which corrected the blurred pictures in its first service mission. The Cosmic Origins Spectrograph focuses on ultraviolet light. Because of the Cosmic Origins Spectrograph, the Hubble’s sensitivity was improved ten times more in the ultraviolet light and increases up to 70 times when looking at extremely faint objects. The purpose of the Cosmic Origins Spectrograph is to break down radiation using the ultraviolet light. The Cosmic Origins Spectrograph, otherwise abbreviated to COS, studies the evolution of the galaxy and the universe around us.
The Space Race began in or around the late-1950s, during the Cold War. The United States and Russia were both anxious to become the country to explore space. Unfortunately for the US, Russia launched the first artificial satellite and man-made object to orbit Earth, Sputnik. The launch of Sputnik surprised the United States, and we rushed to get our own space craft into space, and to beat Russia to anything else space related.
October 4, 1957: The Russia launched Sputnik into space. Thus began the seemingly-eternal battle for control of space exploration. Who would get the first man into space; to the Moon, to Mars? Everything that could be done by either country was being done to give the edge. It soon became obvious to all that neither country was going to back down from the challenge. However, a lot has changed since 1957, governments have slumped, privatized exploration has taken charge. . . what happened? Where is space exploration going? Where is the human race, today?
As a country we need to start investing more money and research into space technology. Programs currently exist for this effort, but the potential for research and progress is limited by a lack of funding; compared to other government funded programs, aerospace funding is pitiful. Continued research in space technology is a necessary step in our growth and development not just as a country but also as entire human race. If we are to achieve this goal, it is necessary to increase funding for space research and technology and consider the possibility of colonizing outer space. If we limit our existence to the planet Earth, and continue to drain the resources on this planet, we will destroy the only home we have.

In comparing the 1591 and 1598 versions of Sir Phillip Sidney’s “Astrophil and Stella”, it is said that the 1598 publication proves to be the most authoritative version. The 1598 edition, published along with other works in Sidney’s Arcadia, contains many spelling, grammar, and punctuation corrections; a complete restructuring and organization of the sonnet sequence; as well as the replacement of lines that had been missing or miscopied in the original 1591 edition. The differences between the two editions are especially prevalent in the first and sixth sonnets of the poem. While these corrections are seemingly subtle, they prove to be important in supporting the framework of the Petrarchan
“That’s one step for man, one giant leap for mankind.” That is one of the most memorable quotes said by Neil Armstrong (1969) when he landed on the moon. However, do you know about the previous events that lead to this remarkable achievement? Also, do you know about all the the other remarkable space achievements? This includes the motivation from President Kennedy’s speech, the successful use of satellites, and the previous manned missions. These events all helped in getting a man to land on the moon, which soon led to the conclusion of the Space Race. The course of action taken by America helped lead them to success when they landed a man on the moon.
A majority of people think the space program is a lost cause, a waste of money and a risk that should not be taken. These are all exceptional reasons why we should not fund the space program, however, there are more pros than cons in the fact of the matter. In 1969 Neil Armstrong took the first steps on the moon, this was one of the immense accomplishment of the space program that will be remembered for centuries to come. We want our children to experience these events just as we did When we were kids and the space program can do just that. Space program funding should be increased because of the human's need for exploration, greater technological advances and how it could improve the lives of people on earth.
never heard of? Thanks to space probes these dreams may become a reality sooner than u think. In the past years there have been many space probes launched and even more discoveries made by them. These probes are helping people to better understand our solar system and everything it. They are also helping to make many new discoveries.
Human fascination with the stars is as ancient as Babylonians and has been suggested to be older than Stonehenge. From “be fruitful and multiply” to “live long and prosper,” the instinct to protect and propagate the species has manifested in religion, art, and the imaginations of countless individuals. As human understanding of space treks out of the fantastical and into the scientific, the realities of traveling through and living in space are becoming clearer. Exploring, investigating, and living in space pose an expansive series of problems. However, the solutions to the problems faced by mankind's desire to reach beyond the horizon, through the night sky, and into the stars are solutions that will help in all areas of life on Earth.
