25 Facts on Nasa
By Jay B.
Here are some key facts about NASA (National Aeronautics and Space Administration):
1. NASA was established on July 29, 1958 by the National Aeronautics and Space Act.
2. The 2009 budget for NASA is $17.6 billion dollars.
3. With it's motto as "For the Benefit of All", NASA was influenced by the space race, with the launch of the Soviet space program's first human-made satellite, Sputnik 1, on October 4, 1957.
4. The Apollo program, which was a spaceflight program from 1961-1975, was designed to land humans on the Moon and bring them back safely to Earth. Apollo 1 tragically ended when all the astronauts on board were killed due to the fire in the command module during an experimental simulation. Apollo 11, on July 20, 1969, landed the first men on the moon, Neil Armstrong and Buzz Aldrin.
5. The six missions of the Apollo program returned almost 400 kilograms of lunar samples with experiments including meteoroids, heat flow, seismic, lunar ranging, soil mechanics, magnetic fields, and solar wind experiments.
6. The Skylab was the first space station that the United States had launched into orbit. From 1973 to 1979, this 75 tonne station was in Earth's orbit. It's purpose was to study gravitational anomalies in other solar systems, but was curtailed due to lack of funding and interest. The station was visited by crew three times in 1973 and 1974.
7. The Apollo-Soyuz was the first joint flight of the U.S. and Soviet space programs. This took place in July 1975.
8. The major focus of NASA in the late 1970s and 1980s was the Space Shuttle.
9. The United States and Russia are the two biggest partners in the largest space station ever built, the International Space Station. It was been difficult for NASA to justify the ISS because it costs over $100 billion dollars.
10. The 1990s was a difficult time for NASA, facing shrinking annual budgets due to Congressional belt-tightening in Washington D.C. NASA's ninth administrator, Daniel Goldin, in response, pioneered the "faster, better, cheaper" approach that enabled NASA to cut costs while still delivering a variety of aerospace programs.
11. As of December 2006, NASA has made 116 successful launches.
12. The current space policy of the United States is "execute a sustained and affordable human and robotic program of space exploration and develop, acquire, and use civil space systems to advance fundamental scientific knowledge of our Earth system, solar system, and universe."
13. Ongoing investigations of NASA include in-depth surveys of Mars and Saturn and studies of the Earth and the Sun.
14. One NASA spacecraft is presently en route to Mercury and Pluto.
15. NASA's itinerary covers over half of the solar system, with missions to Jupiter in the planning stages.
16. In 2011, an improved and larger planetary rover, Mars Science Laboratory, is slated to launch.
17. The New Horizons mission to Pluto was launched in 2006 and will fly to Pluto in 2015. The probe received a gravity assist from Jupiter in February 2007, which examined Jupiter's inner moons.
18. The MAVEN spacecraft is on the horizon of NASA's plans and is part of the Mars Scout Program to study the atmosphere of Mars.
19. The Vision for Space Exploration is the United States space policy that was announced on January 14, 2004, by United States President George W. Bush that in 2018, mankind will return to the moon and set up outposts as a testbed and a potential resource for future missions.
20. In 2010, the Space Shuttle will retire and be replaced by Orion by 2015, which is capable of both docking with the International Space Station and leave the Earth's orbit.
21. On September 28, 2007, NASA administrator Michael D. Griffin stated that NASA aims to put a man on Mars by 2037, and in 2057, "We should be celebrating 20 years of man on Mars."
22. NASA announced on December 4, 2006 that it was planning on building a permanent moon base.
23. NASA's headquarters is located in Washington, D.C.
24. The Administrator of NASA is the highest-ranking official and serves as the senior space science adviser to the President of the United States.
25. NASA remains to be the only space agency to have launched space missions to the outer solar system beyond the asteroid belt.

Robots - The Future For NASA?
By Doug Wetzel
Impossible. That's what the 2009 Augustine committee reported about prospects for NASA's human exploration of space, at least for the next seven years. NASA's budget issues remain at the top of the list holding humans from space but the same future may not hold true for its robots.
Two recent robot adventurers, rovers Spirit and Opportunity, lend credence to the idea that NASA's future may rapidly become reliant on robots to carry out missions in space. The Mars exploring rovers cost the agency more than $400 million apiece but have returned nearly six years of insightful data and imagery from the red planet's surface.
Contrast this against the charge for merely launching human passengers into orbit via space shuttle, at roughly $450 million per launch, and the fiscal benefits become quickly apparent. Not to mention, space shuttles such as Endeavour cost the agency almost $1.7 billion to manufacture alone.
NASA's Space Faring Robots of the Past
The Mars rovers aren't the first robots to plumb the mysteries of space for NASA. In fact, robots have investigated and visited more locations in our solar system than any human--oftentimes to locales an astronaut couldn't survive.
In 1973 the robotic space probe Mariner 10 traveled to the inner system planets of Mercury and Venus while its younger sister, Mariner 9, made the trip to Mars more than thirty years before Spirit and Opportunity. Alongside, Pioneer Venus 2 ejected robotic probes which dared an actual foot landing on the surface of Venus, a vacation spot bragging temperatures well over 800 degrees Fahrenheit.
One of those probes managed to survive the risky descent and dutifully report back for 45 minutes inside roasting temperatures and atmospheric pressure that no sane human would tempt. Clearly robots can take an exploratory role that would be too costly and too dangerous for a person.
While we have managed to put footprints and flags on our nearby Moon, robots have traveled to virtually all of the planets and even some of their moons. Of course, robots have visited our rocky celestial partner as well, among them include various NASA Pioneer spacecraft and an array of Soviet Luna spacecraft. Most of these robotic Moon explorers have taken a role as simple orbiters but a few have impacted the surface to pick through rocks and wander the barren surface.
NASA Robots on Earth
Many ideas and projects for robots at NASA have inevitably filtered down to worthy applications on Earth. After all, it is sometimes expensive or dangerous for a human to travel and visit locations on our own space rock.
One example is the Altus II, a robotic airplane developed by NASA. Originally designed as a scientific aircraft, in 2001 NASA presented the craft as a tool for fighting fires.
Human pilots have often risked their lives piloting aircraft in an attempt to survey and monitor deadly, often vast, wildfires. Because the Altus II can fly for such long duration--at one time the craft held a 26-hour record for single-flight endurance--it can continually co-operate with both ground based firefighters and off-planet satellites to photograph and monitor fires below.
In the future, NASA is likely to entertain ideas for using this sort of UAV (unmanned aerial vehicle) in a role exploring and monitoring the surface of alien worlds, carrying out automated scientific experiments at high-altitude, and coordinating with other robots on the ground and in space alike.
A Future for NASA Robots
Sure to be the envy of every earth-bound grasshopper, the Jollbot is wiry, robotic contraption that may take a leap for NASA's future exploration of space.
Robots that physically walk on some sort of leg or roll around on a set of wheels can easily be thwarted by unpredictable terrain. The Jollbot takes a different tack by literally forming a ball to roll across obstacles. If things get too tough, or if there are simply better places to explore, the Jollbot can hop its way to a distant new location or hurdle over a small patch of difficult ground before continuing its mission.
Such a robot could provide a far cheaper and far more efficient answer than previous attempts made by NASA at exploring other planets and moons. It also means that NASA could send many more of these robotic explorers than usual opening up the possibility of mapping and traversing entire landscapes in short periods of time, both on our home planet and anywhere in space we can afford to send them.
A much more human like robot is also being developed by NASA and DARPA--the Robonaut. Featuring an upper torso, human styled hands and arms, and even a head straight out of your favorite science fiction movie, the Robonaut has been proposed as the ideal space janitor and maintenance man.
Capable of being mounted in ways we humans might find offensive, the Robonaut could find itself perched on the end of a long, robotic arm for spacewalks intended to repair and maintain equipment such as found on the International Space Station or orbiting satellites. Partnered with humans, a Robonaut could make these spacewalks safer and easier, if not less time-consuming and costly.
Yet, the Robonaut isn't by any means limited to jaunts in space. One lucky Robonaut has been mounted on a Segway HT, the hip, two-wheeled electric scooter that has periodically foiled human riders such as George Bush.
It is certainly possible that NASA could find even more inventive ways to mount a Robonaut, on Earth, in space, and into the distant future. Whatever the case, it is apparent that robots form an effective cast and crew for NASA's future exploration of our planet and our universe.
