An Austrian Scientists Use LASER & iPhone To Detect Microbes On Mars Space Suit

Finding out life on other planets has always been a human endeavor. Many missions have been planned and sent to outer space in search of some alien life. However the possibility that microorganisms clinging to the space suit of astronauts who are out on the mission to find aliens cannot be neglected. It may lead to confusion whether the organisms are from earth or other planets. Well it may be a tricky aspect but it has been solved by scientists for astronauts going to mars.
he program of developing foolproof techniques for detection of microbes on space suit is a part of Austrian Space Forum’s PolAres mission. Austrian scientists are taking use of the laser-induced-fluorescence emission (L.I.F.E) technique which was also earlier used in detection of microbes in Antarctica. The technique may sound difficult one but it is actually simple. It requires only a LASER pointer and an iPhone. The LASER pointer is directed towards the space suit and if it contains any microbe, it emits a fluorescent glow. The glow is then processed with digital photography and laptops. If the microbe is any known one, it takes only a few seconds. The scientists want to be sure for the samples being brought from Mars to be genuine. The technique is designed for both forward and reverse contamination. While returning to earth, there may be contamination from microbes, if present on mars.

The development of new techniques is not only limited to detection alone. Austrian scientists are also developing techniques to shake away the organisms. The team of scientists led by Gernot Groemer, president of the Austrian Space Forum has designed an electromagnetic method for the same. For that all the astronauts have to do is that to attach the space suit to high voltage electric charge which would make the dust particle and micro organisms to levitate away from the space suit. The dust particles can then be blown away with the help of a stream of air. Earlier, vibration techniques were used for the purpose; however they are not as effective as this one. As per the simulations conducted by scientists, it is found that around 60 to 405 bacteria can cling within minutes of cleaning the suit.

The techniques developed are expected to be the part of The ExoMars rover to be launched in 2018. The current research and studies are conducted in the desert of San Rafael, Utah. The technology developed would increase the credibility of samples from mars. It will be a step ahead in human search for Alien life.

Dawn Planetary Delights

During the month of May, four bright Planets will grace the morning sky just before dawn.

The planets Venus, Jupiter, Mercury and Mars will be involved in a series of conjunctions (close together) and will finally be joined by the thin crescent moon at the end of the month.

Twice during May some of the planets will converge to form a trio, where 3 planets will fit in an imaginary circle roughly 5 degrees across.

On the 11th Mercury, Venus and Jupiter will be within 2.5 degrees of each other, forming a very tight trio and on the 21st another trio will be formed by Mercury, Venus and Mars.

On the 29th, 30th, and 31st, the waning crescent moon will arrive, moving past Jupiter, Mars, Venus and Mercury stretched out in a line across the eastern sky.

Space Shuttle Mission

At NASA's Kennedy Space Center in Florida, technicians are preparing space shuttle Atlantis for its move from Orbiter Processing Facility-1 to the Vehicle Assembly Building, or VAB, next month.

Final preparations in the shuttle's aft section are complete and crews are working on the forward sections now. The main landing gear is set to be leak tested and the hydraulic fluid level will be checked today.

Battery installation and testing for the wing leading edge sensors is ongoing. The sensors help monitor the reinforced carbon carbon heat shield panels on the shuttle’s wings for possible debris impacts. The payload bay doors will be closed Friday for rollover.

Meanwhile in the VAB, Atlantis' external fuel tank and solid rocket boosters have been stacked on the mobile launcher platform in High Bay 2.

Hubble Opens New Eyes on the space

NASA's Hubble Space Telescope is back in business, ready to uncover new worlds, peer ever deeper into space, and even map the invisible backbone of the universe.

The first snapshots from the refurbished Hubble showcase the 19-year-old telescope's new vision. Topping the list of exciting new views are colorful multi-wavelength pictures of far- flung galaxies, a densely packed star cluster, an eerie "pillar of creation," and a "butterfly" nebula.

With the release of these images, astronomers have declared Hubble a fully rejuvenated observatory. Sen. Barbara A. Mikulski, D-Md., unveiled the images at NASA Headquarters in Washington, D.C., on Sept. 9, 2009.

With its new imaging camera, Hubble can view galaxies, star clusters, and other objects across a wide swath of the electromagnetic spectrum, from ultraviolet to near-infrared light. A new spectrograph slices across billions of light-years to map the filamentary structure of the universe and trace the distribution of elements that are fundamental to life.

The telescope's new instruments also are more sensitive to light and can observe in ways that are significantly more efficient and require less observing time than previous generations of Hubble instruments.

NASA astronauts installed the new instruments during the space shuttle servicing mission in May 2009. Besides adding the instruments, the astronauts also completed a dizzying list of other chores that included performing unprecedented repairs on two other science instruments.

Now that Hubble has reopened for business, it will tackle a whole range of observations. Looking closer to Earth, such observations will include taking a census of the population of Kuiper Belt objects residing at the fringe of our solar system, witnessing the birth of planets around other stars, and probing the composition and structure of the atmospheres of other worlds.

Peering much farther away, astronomers have ambitious plans to use Hubble to make the deepest-ever portrait of the universe in near-infrared light. The resulting picture may reveal never-before-seen infant galaxies that existed when the universe was less than 500 million years old. Hubble also is now significantly more well-equipped to probe and further characterize the behavior of dark energy, a mysterious and little-understood repulsive force that is pushing the universe apart at an ever-faster rate.

Longest Solar Eclipse of the 21st Century

One one-thousand, 2 one-thousand, 3 one-thousand, 4 one-thousand...Continue counting and don't stop until you reach 399 one-thousand. Did that feel like a long time? Six minutes and 39 seconds to be exact. That's the duration of this week's total solar eclipse--the longest of the 21st century.

The event begins at the crack of dawn on Wednesday, July 22nd, in the Gulf of Khambhat just east of India. Morning fishermen will experience a sunrise like nothing they've ever seen before. Rising out of the waves in place of the usual sun will be an inky-black hole surrounded by pale streamers splayed across the sky. Sea birds will stop squawking, unsure if the day is beginning or not, as a strange shadow pushes back the dawn and stirs up a breeze of unaccustomed chill.

Most solar eclipses produce this sort of surreal experience for a few minutes at most. The eclipse of July 22, 2009, however, will last as long as 6 minutes and 39 seconds in some places, not far short of the 7 and a half minute theoretical maximum. It won't be surpassed in duration until the eclipse of June 13, 2132.

From the Gulf of Khambhat, the Moon's shadow will race east across India, China, and the Ryukyu Islands of Japan. Click on the image to launch an animated map:

The path of totality cuts across many large cities. The shadow will linger over Shanghai, the largest city in China, for six full minutes, giving 20 million residents a lengthy and stunning view of the sun's ghostly corona. Other large cities in the path of totality include Surat, Vadodara, Bhopal, Varanasi, Chengdu, Chongqing, Wuhan, Hefei, Hangzhou. The population of each numbers in the millions, making this possibly the best-observed solar eclipse in human history.

The eclipse is extra-long because of a lucky coincidence, made possible by the elliptical shape of planetary orbits. On July 22nd, Earth happens to be near its farthest point from the sun. A small sun means the Moon can cover it longer. At the same time, the Moon will be near its closest point to Earth. A large Moon covers the sun longer, lengthening the eclipse even more.

The leisurely pace of the eclipse could have a transformative effect on witnesses. Total eclipses have been known to turn ordinary folk into life-long "eclipse-chasers" willing to spend thousands of dollars and travel tens of thousands of miles to feel the Moon's cool shadow and behold the sun's pale atmosphere just one more time. A few extra minutes of wonder will intensify this effect to an unknown degree.
