Aliens exist but they may be dangerous: Hawking April 26, 2010 - 12:34PM

Aliens may exist but mankind should avoid contact with them as the consequences could be devastating, British scientist Stephen Hawking warned on Sunday.

"If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans," the astrophysicist said in a new television series, according to British media reports.

The programmes depict an imagined universe featuring alien life forms in huge spaceships on the hunt for resources after draining their own planet dry.

"Such advanced aliens would perhaps become nomads, looking to conquer and colonise whatever planets they can reach," Hawking warned.

The doomsday scenario is suggested in the series Into the Universe with Stephen Hawking on the Discovery Channel, which began airing in the United States on Sunday.

On the probability of alien life existing, he says: "To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.

"The real challenge is to work out what aliens might actually be like."

Glowing squid-like creatures, herds of herbivores that can hang onto a cliff face and bright yellow predators that kill their prey with stinging tails are among the creatures that stalk the scientist's fantastical cosmos.

Mankind has already made a number of attempts to contact extraterrestrial civilisations.

In 2008, American space agency NASA beamed the Beatles song Across the Universe into deep space to send a message of peace to any alien that happens to be in the region of Polaris - also known as the North Star - in 2439.

But the history of humanity's efforts to contact aliens stretches back some years.

The US probes Pioneer 10 and 11 were launched in 1972 and 1973 bearing plaques of a naked man and woman and symbols seeking to convey the positions of the Earth and the sun.

Voyager 1 and 2, launched in 1977, each carry a gold-plated copper phonogram disk with recordings of sounds and images on Earth.

A TV show on the theory that modern man was created by the aliens through DNA manipulation. Interesting how they combine scientific DNA theory with religious stories & mythology.

Dead Spacecraft on Mars Spotted in New Photos
Date: 09 February 2012

A NASA probe orbiting Mars has captured a new photo of two dead spacecraft frozen in place at their Red Planet graves.

The photo was taken by NASA's powerful Mars Reconnaissance Orbiter (MRO), which has been circling the planet since 2006.

The spacecraft first spied NASA's dead Phoenix Mars Lander in the Martian arctic on Jan. 26 in a color photo that reveals the lander and its frigid surroundings as they appeared following Phoenix's second winter on the planet. The Phoenix spacecraft landed successfully on Mars in 2008.

In a separate photo, MRO also spotted the three-petal landing platform that delivered NASA's Mars rover Spirit to the surface of the Red Planet in January 2004. The platform used parachutes and airbags to bounce to a stop on Gusev crater so the Spirit rover could begin its mission.

Spirit drove off the lander platform in January 2004 and spent most of its six-year working life in a range of hills roughly two miles (3.2 kilometers) to the east, NASA officials said in a statement. The rover went silent in 2010 and NASA officially declared it dead last year.

In the MRO image, which was taken on Jan. 29, Spirit's lander platform appears as a bright feature at the bottom left, southwest of Bonneville Crater.

MRO's High Resolution Imaging Science Experiment (HiRISE) camera has recorded color images of the Spirit rover itself before, but all previous photos of the lander platform were in black and white, according to NASA officials.
Dead rover on Mars
Spirit and its twin rover Opportunity were originally designed for three-month missions to look for signs of past water activity on Mars. Both rovers far outlived their warranty, however, and the missions delivered evidence that the Red Planet was once a much wetter, warmer place.

Spirit stopped driving when it became mired in sand in May 2009. Mission scientists then converted the rover into a stationary observatory, and Spirit continued to send back data from its trapped location. But, 10 months later, the rover fell silent after being unable to capture enough sunlight on its solar panels over the course of the Martian winter.

Still, Opportunity remains alive and well on Mars, and last month celebrated a remarkable eight years on the surface of the Red Planet. After a three-year trek, the intrepid rover arrived at the 14-mile-wide (22-kilometer) Endeavour Crater in August 2011. The rover recently uncovered what researchers say is the best evidence yet for liquid water on ancient Mars.

Phoenix rises no more
The Phoenix Mars Lander landed in May 2008 on a mission to search and dig for evidence of water in the Vastitas Borealis plains in the Martian arctic. During its nearly six-month mission, the $475 million lander confirmed the presence of subsurface water ice and made valuable characterizations of Martian dirt.

The Phoenix mission ended in November 2008 when the spacecraft could no longer receive adequate power due to a combination of dwindling sunlight, light-obscuring dust and harsh winter temperatures.

The Mars Reconnaissance Orbiter itself continues to have a prolific career in orbit around the Red Planet. The powerful probe began circling Mars on March 10, 2006 and is currently in an extended phase of its mission.

The orbiter continues to provide valuable insights into the planet's ancient environment and how processes such as wind, meteorite impacts and seasonal frosts are continuing to affect the surface of Mars today, NASA officials said. MRO has transmitted more data to Earth than all other interplanetary missions combined.

Janice Voss, Veteran of 5 Space Shuttle Flights, Dies at 55

Astronaut Janice Voss, a veteran of five spaceflights and a former science director for a NASA exoplanet-hunting spacecraft, has died after a battle with cancer. She was 55.

Chosen by NASA for the astronaut corps in January 1990, Voss served as mission specialist on five space shuttle missions, including the only repeat flight in the shuttle program's 30-year history. She flew with the first commercial laboratory, rendezvoused with Russia's Mir space station and helped create the most complete digital topographic map of the Earth.

Five-time shuttle flier
Voss launched on her first and final missions aboard the shuttle Endeavour. As a member of the STS-57 crew in June 1993, she helped conduct biomedical and material science experiments in the first commercially-developed Spacehab module, a pressurized laboratory mounted in the orbiter's payload bay that more than doubled the work area for astronaut-tended activities.

In February 2000 Voss again launched on Endeavour, this time for NASA's Shuttle Radar Topography Mission. After deploying a nearly 200-foot (60-meter) mast, Voss and her crewmates worked around the clock in two shifts to map more than 47 million square-miles (122 million square-kilometers) of the Earth's land surface. [Shuttle's Best Science Missions]

Voss' second flight to space marked the first time a space shuttle came within the vicinity of Russia's space station Mir. Flying on the shuttle Discovery, Voss and her STS-63 crewmates — including Eileen Collins, the first woman to pilot a U.S. spacecraft — rendezvoused with the Russian outpost to verify flight techniques, communications, and navigation and sensor aids. The February 1995 "Near-Mir" mission set the stage for the first shuttle-Mir docking later that year.

Voss' two other spaceflights, STS-83 and STS-94, were the only time in the shuttle program's history that an entire crew was launched twice to achieve the same mission. The crew's first attempt began with a liftoff on Columbia on April 4, 1997. Three days into the mission however, a problem with one of the orbiter's three power-generating fuel cells resulted in the flight being cut short and the crew members returning to Earth.

Three months later with Columbia back in working order, Voss and her six STS-83 crewmates launched again, this time as the STS-94 crew. During the successful 15-day flight, Voss and her fellow fliers worked inside a European Spacelab module, conducting experiments as part of the Microgravity Science Laboratory (MSL) mission.

In total, Voss logged over 49 days in space, traveling 18.8 million miles (30.3 million km) while circling the Earth 779 times. Her five missions tied her with the record for the most spaceflights by a woman.

Four years after returning to Earth for a final time, Voss transferred from Johnson Space Center in Houston, Texas, to NASA's Ames Research Center at Moffett Field, Calif., where she headed the science program for the agency's Kepler space observatory. Designed to search for Earth size planets orbiting distant stars, Kepler was launched in March 2009 and to date has confirmed 61 exoplanets and identified more than 2,000 planetary candidates.

Mountaintop leveled for giant telescope

by Staff Writers
Pasadena, Calif. (UPI) Mar 23, 2012

Scientists say 3 million cubic feet of rock will be blasted from a mountaintop in the Chilean Andes to make room for what will be the world's largest telescope.

In the coming months more than 70 controlled explosions will break up rock while creating a solid bedrock foundation for the Giant Magellan Telescope, the Carnegie Institution reported Friday.

The huge instrument will be able to peer back to the dawn of time, witnessing the birth of the first stars, galaxies and black holes, while also exploring planetary systems similar to our own around nearby stars in the Milky Way, officials said.

"Today marks a historic step toward constructing an astronomical telescope larger than any in existence today," Wendy Freedman, director of the Carnegie Observatories and chair of the Giant Magellan Telescope Organization, said in a ceremony on the mountaintop site of Carnegie's Las Campanas Observatory.

The Las Campanas site is renowned as one of the world's premier astronomical sites, known for its pristine conditions and clear, dark skies.

"Years of testing have shown that Las Campanas is one of the premier observatory sites in the world and the Carnegie Institution is proud to host the GMT."

The Giant Magellan Telescope is being built by a consortium of U.S., South Korean and Australian institutions.

Seven primary mirrors, each 28 feet in diameter and weighing 20 tons, will form the heart of the giant telescope providing nearly 4,000 square feet of light-gathering area, astronomers said.

Space Shuttle Enterprise's Historic Flyover Wows New Yorkers
by Denise Chow 27 April 2012

Hundreds of space shuttle fans braved the chilly temperatures and biting wind Friday morning (April 27) along the Hudson River here to catch a glimpse of NASA's prototype orbiter as it flew past the museum it will soon call home.

Enterprise, the agency's original test shuttle, flew to New York today from Dulles International Airport in Washington, D.C., atop a modified Boeing 747 jet. Before landing at New York's John F. Kennedy (JFK) International Airport, the piggybacking duo flew over the Statue of Liberty, then followed the Hudson River past the Intrepid Sea, Air and Space Museum, where it will soon be placed on public display.

Russia brings three spacemen safely back to Earth
by Staff Writers
Moscow (AFP) April 27, 2012

Two Russian spacemen and a NASA astronaut touched down safely Friday in the Kazakh steppe aboard a Soyuz capsule after a stay of almost six months aboard the International Space Station.
Seventeen Russian helicopters and jets patrolled the clear blue skies as the silver metal capsule parachuted gracefully through the air before bumping into a field of straw and early spring grass and rolling over gently onto its side.

Live NASA TV footage showed a team of medics swarm the capsule and pull out a smiling Anton Shkaplerov -- a Russian awarded the honour of breathing the fresh air first because he occupied the capsule's middle seat.
Shkaplerov appeared "in good shape and none the worse for wear," a NASA commentator said as the spaceman gave a thumbs-up sign from inside his bulky white suit.

The three men were soon whisked away for a quick change of clothing and to pull on some special socks designed to improve their circulation and reduce the potential threat of blood clots and strokes.

Shkaplerov and his Russian counterpart Anatoly Ivanishin and American Dan Burbank will be replaced by a new crew that is due to take off from Russia's Baikonur cosmodrome in Kazakhstan on May 15.
They will be joining Oleg Kononenko of Russia and Andre Kuipers of The Netherlands as well as NASA's Don Pettit on a mission that is also expected to last about six months.

The team's return was also delayed by 42 days after one of the Soyuz capsules was found to heave a leak in its hermetic seal.
Russia's once-proud space programme has been beset by problems in the past year that have seen rockets fail to reach orbit and space exploration missions go awry.

The problems are a particular worry for NASA, which retired its space shuttle programme last year. The Soyuz now provides the world's only manned link to the ISS.

'Supermoon' Alert: Biggest Full Moon of 2012 Occurs This Weekby SPACE.com 30 April 2012

Skywatchers take note: The biggest full moon of the year is due to arrive this weekend. Skywatcher Tim McCord of Entiat, Washington caught this amazing view of the March 19, 2011 full moon - called a supermoon because the moon was at perigee, the closest point to Earth in its orbit - using a camera-equipped telescope.

The moon will officially become full Saturday (May 5) at 11:35 p.m. EDT. And because this month's full moon coincides with the moon's perigee — its closest approach to Earth — it will also be the year's biggest.

The moon will swing in 221,802 miles (356,955 kilometers) from our planet, offering skywatchers a spectacular view of an extra-big, extra-bright moon, nicknamed a supermoon.

And not only does the moon's perigee coincide with full moon this month, but this perigee will be the nearest to Earth of any this year, as the distance of the moon's close approach varies by about 3 percent. This happens because the moon's orbit is not perfectly circular.

This month's full moon is due to be about 16 percent brighter than average. In contrast, later this year on Nov. 28, the full moon will coincide with apogee, the moon's farthest approach, offering a particularly small and dim full moon.

Though the unusual appearance of this month's full moon may be surprising to some, there's no reason for alarm, scientists warn. The slight distance difference isn't enough to cause any earthquakes or extreme tidal effects, experts say.
However, the normal tides around the world will be particularly high and low. At perigee, the moon will exert about 42 percent more tidal force than it will during its next apogee two weeks later, Rao said.

The last supermoon occurred in March 2011.

To view this weekend's supermoon to best effect, look for it just after it rises or before it sets, when it is close to the horizon. There, you can catch a view of the moon behind buildings or trees, an effect which produces an optical illusion, making the moon seem even larger than it really is.

Anyone who has taken the time to examine the evidence can come to no other conclusion than that SOME UFOs are alien spacecraft. It's a no-brainer. But you have to look at the evidence, and most people aren't willing to do that.
