Climate Research Shows: Greenland Ice Sheets Melting Faster Than the Expectations

December 16, 2014 By Germaine Hicks Leave a Comment

A new study dismissed all the early predictions of melting ice sheets of the Greenland. It demonstrates that previously scientists underestimated the ratio of the melting ice sheets. These ice sheets would probably cover double of its current land till 2060.

The melting ice sheets of Greenland plays a vital role in the elevation of sea level. The ignored impact of global warming can considerably increase the proportion of melting ice sheets.

NASA observed changes in the huge Ice Sheets of Greenland in the last five years. Recently, experts accumulated data from NASA and released a comprehensive image of the alteration in ice sheets.

The picture reveals the entire process through which ice sheets moves towards the sea. It provides significant information regarding the melting of water beneath the snow surface.

The chief goal of the study is to offer information which can help scientists in making an exact prediction of the melting of Greenland ice sheets. The outcome of the study shows that the melting of all the ice sheets can increase the level of oceans up to 6 meters. Such an increase would certainly cause a great harm to the coastal communities. Currently, the ice sheets of Greenland are 1.7 million square kilometer wide.

As per the early predictions, these melted ice sheets of Greenland mount up the sea level up to 22 centimeters till 2100. However, the new study completely rejected all these assumptions.

Dr. Amber Leeson, a researcher of University of Leeds’ School of Earth and environment informs that super glacial lake can boost up the present speed at which ice sheets melts. The new report uncovers that the region of Greenland would be double in the future.

The report is explained in detail in the Journal Proceedings of the National

NASA’s Orion Capsule Reached Launch Pad for its Test Flight

November 13, 2014 By Rebecca McGhee 1 Comment

NASA’s new Orion spacecraft has finally reached the launch pad for the next month’s test flight. The spaceship is specially designed to take astronauts to the places beyond the International Space Station. Some of the planned targets of this spacecraft are Mars and Moon.

The Lockheed Martin Space Systems built this gum-drop shaped spacecraft which is known as Orion. It travelled 22 miles, 6 hours journey to reach the Cape, Canaveral launch pad of Florida.

Later on, the experts lifted the spacecraft to the top of Delta IV for the first unmanned flight of 4th December. The Delta IV rocket is designed by the United Launch Alliance. In the next few weeks, the experts will put the rocket and spacecraft together to prepare them for the test flight.

Afterwards, the scientists will check the computer, parachutes, heat shield and other equipments of the new spacecraft.

The orbital test flight of Orion will end in a very short time period of four hours. The spacecraft will move twice around the planet Earth. The spacecraft will travel approximately 3,600 miles away from the planet in order to crash into the atmosphere with the high speed of 20,000 miles per hour. As per the expectations of scientist, the heat Shield of Orion will reach the temperature of around 4,000 Fahrenheit.

Furthermore, the test flight of Orion will provide significant information regarding the performance of systems, recovery operations and the working of huge Colorado- built heat shield.

Bob Cabana, director of Kennedy Space Center informed that it is the first step towards the trip to Red Planet.

HP Unveils 3D Scanner/Printer with Multi Jet Fusion Technology

October 30, 2014 By Brian Galloway Leave a Comment

At last, HP reveals its new 3D printer after three years of continuous struggle. The American based company is really famous for its conventional ink printers.

Hp flaunted its brand innovative new multi Jet Fusion Technology in an event of New York. The company announced that this new product will take almost two years to touch the markets of printers.

The company has specially designed 3D printer for fast printing in low price. The firm claimed that it works nearly ten times faster as compared to the ordinary printer available in the markets. Furthermore, the device offers a scanner, depth sensor, projector, high-res camera and much more.

Hp has incorporated Jet Fusion Technology which makes use of a print bar that generates more than 350 drops per second at 21 microns. It signifies that the printer would print approximately 1,000 gears in just a short time period of three hours. The company has specially designed an ink which will increase the speed of this Multi Jet Fusion Printer. In short, the new Multi Jet printer will take care of three of the main areas of a printer; speed, cost and time.

The device works in a really appealing manner. First, it coats the material then a print bar put on fusion agent. Later on, this Fusion agent scans the material and opens it for the energy source so that it can join together.

Moreover, a detailing agent is also utilized to enhance the edges of the particular object.

Alan Eustace, Google Executive Sets New Altitude World Record

October 25, 2014 By Rebecca McGhee Leave a Comment

Alan Eustace breaks the record of Austrian Felix Baumgartner. In 2012, Baumgartner gained everyone’s attention when he jumped from a helium filled balloon. He flew more than 24 miles in order to get back to the Earth.

Recently, Alan Eustace set a new altitude world record of the parachute jump. Eustace is a 57 year old computer scientist and senior vice president of Google.

He parachuted from the top of the stratosphere, which is the second major layer of the Earth’s atmosphere on Friday. The layer is nearly 40km (25 miles) above the planet Earth.

The man wore a specially designed space suit in order to begin his journey from New Mexico. He arrived back to Earth with a speed of more than 1,300km/h.

He traveled with the speed greater than the sound, light and other things of the atmosphere. Therefore, he returns to Earth just in a short time period of 15 minutes.
Eustace jumped from a helium balloon packed with almost 35,000 cubic feet of helium. He set himself free with the help of a tiny explosive device. The blast heard like a small sonic boom by the viewers of this wonderful sight.

Later on, Mr. Eustace expressed that it was an indescribable experience for him. Moreover, he informed that he was secretly planning for this jump since past few years. He worked with a small panel that are considered as the best in the arena of balloon and parachute technology.
