Servicing Missions to the Hubble Space Telescope
The Hubble Space Telescope received its first Service Mission in December 1993. The missions most important objective was to install two devices to fix the Hubble Telescope's vision problem . The space telescope could not focus all the light from an object to a single sharp point because Hubble's primary mirror was incorrectly shaped. Instead it saw a fuzzy halo around objects it observed in space.
Interesting facts about Hubble Space Telescope is there is no question that the Hubble Telescope gave us amazing pictures and views of very early distant galaxies. But because the universe is expanding, the light from the most distant space galaxies is shifted to infrared wavelengths. So to see the galaxies the Hubble neede to be fitted with an instrument that could observe infrared light.
In Feb. 1997 the Hubble Telescope received its Second Servicing Mission. The space shuttle Discovery was boarded by seven astronauts. They installed two technologically advanced instruments, onto the Hubble. To observe space objects in infrared wavelengths the Near Infrared Camera and Multi-Object Spectrometer was installed. The second instrument installed was the Space Telescope Imaging Spectrograph, which is used to take detailed pictures of celestial objects and hunt for black holes.
Service Mission 3A in December 1999 was a busy one for the space telescope. Their goal was the replacement of gyroscopes, which accurately point the Hubble at celestial targets. The crew replaced all six gyroscopes as well as one of Hubble's three fine guidance sensors, which allow fine pointing and keep Hubble stable during space observations.
Service Mission B for the Hubble Telescope occurred on March 1st 2002 when NASA launched the space shuttle Columbia, where its seven member crew met with Hubble to perform a series of upgrades. The astronauts performed five spacewalks. Their mission was to install the Advanced Camera for Surveys. The ACS doubled Hubble's field of view and collects data ten times faster than before.

Preventing Flooding on Individual Farmers Fields to Save Crops
I propose permits be given to farmers to they can set up along the edge of their fields a microwave array to burn a hole in the clouds when severe weather threatens their crops. I would propose that this concept be completely privately funded and be done in conjunction with the FAA.
Dream Therapy and Learning thru Human Hibernation
Want to learn a new language? Would you like to earn a PhD in Physics; perfect your backstroke tennis swing, golf finesse or fly-fishing techniques, while you sleep? While, your immune system catches your body back up on your lack of exercise, fitness and proper diet? How about if I told you, that you most likely will shed about 20-25 lbs of extra weight while all this is going on? Well, if we further develop our sleep research, human hibernation studies and mind or brain advances we will be able to do all this and more in the near future, perhaps less than 5-years.Let me tell you about a few of the latest new rapidly approaching and potentially converging technologies, which will make all this possible.
Static Charge Pulse on Wind Generator Material Memory Blades
Wind Power is considered a clean industry and is amongst the favorites of environmentalists and clean energy supporters. Unfortunately the wind generators rely on the wind and the wind is somewhat inconsistent in that sometimes it blows and some times it does not.
The Fall and Fall of the p-Zine
Crop Circles and Genetic Knowledge
The crop circle enigma is not always a hoax. I am not able to see how someone could do a massive design overnight in the cases where the plants have their stems broken from within.
Hibernate Enemy with Gas Cloud
Scientists have discovered chemicals, which cause humans to go into a hibernation type state similar to our mammal cousins the bear. This discovery has many killer applications from first responders slowing the bio-systems of those who are seriously injured to long-term space flight or even stopping a civil unrest or riot, which has gotten out of control.
Aliens in Archaeology
As you read this book you will have to suspend the disbelief you feel when confronted with my assertions that for at least 5000 years man has been in close contact all over the world. If you have read my other books you will know I have made the case better than any and that there are lots of good scholars who agree with me.
Locusts To Help Make Energy From Bio Waste, part II
If we take the menace, nuisance and destructive Locust, we can create a win/win situation by and allowing it to survive and happily eat our bio-waste filling up our dumps. Then as it progresses and digests the food it will create energy.
Bio-Rhythm Disruption Frequency Identifier for Human Intentions
It appears we have found many identifiers for Bio-Metrics to identify people. In this new age of International Terrorism with bad guys trying to get Pilot's Licenses, HazMat Driver's Licenses, get onto airlines, step onto buses and sneak over our borders we need a fool proof system.
Saving People in Disaster Crisis, Concept
So often when we see huge Natural Disasters there are many people killed, but for everyone who perishes there are 5-10 people injured; many very seriously. So often too the region of the world were the disaster occurs does not have enough hospital beds, medical professionals or the right equipment needed to help save those lives.
What is Dowsing?
Dowsing is definitely an intuitive art and one of the oldest forms of divination in the world. Perhaps the oldest and most familiar image we have a dowser is what is called a field or map dowser.
X-37 UAV Has Potential
X-37 Moves Forward, Now What? Well, here are a few ideas of taking this craft to a whole new level and plateau in American Ingenuity and Innovation. NASA has learned a lot from the X-37 tests and will now turn it over to DARPA, which makes a lot of sense indeed.
Bees Wax; History and Origin
We have often been asked where wax comes from? Well there are many types of Waxes. Bees wax has been around for a while.
UAV - Terrain Following Technologies
There are many technologies being used today such as ultrasonic sensors, which provide non-contact for solution levels in liquid storage tanks. Using this technology the tanks can use non-corrosive methods to prevent failure of parts.
Tactile Pressure Sensors for Future Robotics
Scientists and Robotic Researchers are attempting to design human type personal assistance robots. As they work to develop algorithms, which most resemble the thought processes of the human brain others are attempting to make them more life like thru human behavioral techniques of mirroring and facial features.
Troubleshooting Pump Problems the Easy Way
In any problem analysis, we have to specify the problem, check whether there is any deviation from the normal condition, identify the possible causes, evaluate the possible causes and then confirm the true cause.Pumps or other machinery will give tell tale signs when they are not working properly.
Cloaking the Postage Stamp Modern Aircraft Carrier
By using a special coating on the deck of an aircraft carrier and a projector on the top of the tallest communications mast facing down, we could project the image of the ocean onto the deck like a giant IMAX theatre screen. Although this sounds like a daunting task, it isn't really.
The Joy of Recycling
I have always been an advocate of recycling. Even though I am not always convinced of its financial viability, I am thoroughly convinced of its value as a means of increasing public awareness of the cost of our consumerism.
What are the Biggest Solar Projects?
Solar power will be necessary for space exploration and off planet colonies on the moon and Mars in the next few decades and our advances here on Earth will assist us with the knowledge we need to power them up. Some may not realize but we have come a long way in our solar technology in the last few decades and we are now ready to take this experience and knowledge to the next level; to build something out of this world.
How Did DNA Testing Children Begin?
The landmark immigration case Sarbah vs. Home Office (1985) was the first to use DNA testing to prove a mother-son relationship between Christiana Sarbah and her son Andrew.
