Pluto’s five moons captured on camera for first time EVER


ESO-L._Calçada_-_Pluto_(by)

PLUTO’S five moons have been captured on camera for the first time EVER as a NASA probe nears the dwarf planet.

The historic moment was recorded by NASA’s New Horizons probe, which is exploring Pluto and beyond.

Previously the probe has only caught footage of Pluto, which was previously downgraded from its status as a full planet, as well as its largest moon Charon and two of its smallest moons – Hydra and Nix.

However, now, Kerberos and Styx, the dwarf planet’s smallest and faintest moons, are also visible.

Detecting these tiny moons from a distance of more than 55 million miles is amazing, and a credit to the team that built our LORRI long-range camera and John Spencer’s team of moon and ring hunters.

John Spencer, programme scientist of the Southwest Research Institute in Colorado, said: “New Horizons is now on the threshold of discovery. If the spacecraft observes any additional moons as we get closer to Pluto, they will be worlds that no one has seen before.”

NASA said initial viewing appeared to show only four moons visible in the footage, but Charon is also in the images – although it blends into the bright centre of imagery.

Pluto’s four smaller moons were discovered by scientists using the Hubble Space Telescope.

Nix and Hydra were found in 2005, while Kerberos and Styx were discovered more recently in 2011 and 2012 respectively.

The unmanned New Horizons probe will start looking for any more more moons and rings around Pluto this month.

However, astronomers fear previously unseen objects in the dwarf planet’s vicinity may put the spacecraft in jeopardy as it heads toward its closest approach in July – and navigators will be very cautious as it nears.

Alan Stern, New Horizons principal investigator, said: “Detecting these tiny moons from a distance of more than 55 million miles is amazing, and a credit to the team that built our LORRI long-range camera and John Spencer’s team of moon and ring hunters.”

New Horizons was launched towards Pluto in 2006.

Once the probe flies past Pluto and its moons on July 14, the spacecraft will continue flying farther from Earth, investigating other cold bodies past the dwarf planet.

Spectacular Images and Video of India From the International Space Station


OB-VP477_inasa1_G_20121207005704

Pictures and footage of India taken from space show the country by night and day as seen from the International Space Station, including a spectacular lightning storm.

The images were taken by Terry Virts, the commander of the current project, Expedition 43, at the space station and tweeted from his verified account.

A one-year joint mission between space agencies in the United States, Russia and Europe, began on Mar. 11, 2015 and is in its final days. Astronauts are expected to return to Earth on Wednesday.

The six-member crew have been conducting astrophysics research, physical science investigations and technology demonstrations, but no space walks.

Two of the crew, Scott Kelly and Mikhail Korneinko, have spent the entire year in space and have undergone medical studies to help further scientific advancements on Earth. Other astronauts were rotated in at the end of Expedition 42 in December.

NASA confirmed Thursday afternoon that its Messenger spacecraft collided into Mercury’s surface at more than 8,000 mph, creating a new crater on the planet.

NOTE : MESSENGER (a backronym of MErcury Surface, Space ENvironment, GEochemistry, and Ranging) was a robotic NASA spacecraft which orbited the planet Mercury.MESSENGER became the second mission after Mariner 10’s 1975 flyby to reach Mercury when it made a flyby in January 2008, followed by a second flyby in October 2008, and a third flyby in September 2009, prior to entering Mercury’s orbit in March 2011. It was the first spacecraft to orbit Mercury.

“Going out with a bang as it impacts the surface of Mercury, we are celebrating Messenger as more than a successful mission,” John Grunsfeld, associate administrator for NASA’s Science Mission Directorate said. “The Messenger mission will continue to provide scientists with a bonanza of new results as we begin the next phase of this mission — analyzing the exciting data already in the archives, and unraveling the mysteries of Mercury.”

But before Messenger’s years-long mission came an end, NASA released several new photos of Mercury, as taken by the spacecraft. Some of these photos were composite imagery, combining years of data and photos collected by Messenger, according to CNET.

Here’s one of the incredible false-color images recently published by NASA. The different colors signify variations in mineral composition, topography and other factors on Mercury’s surface.

Newly Discovered Exoplanet Is The Most Distant Ever Detected

This artist’s conception shows the newly discovered alien planet also Known as OGLE-2014-BLG-0124Lb , which is about 13,000 light-years from Earth.

Astronomers have found an exoplanet nearly 13,000 light-years away, making it one of the most distant planets known to man. This discovery is important not because of the planet itself, a gas giant about half the size of Jupiter, but because what it means for the future of planetary discovery and mapping.

“For context, most of the planets we do know about are a factor of 10-100 times closer than OGLE-2014-BLG-0124,” Dr. Jennifer Yee, a NASA Sagan Fellow at the Harvard-Smithsonian Center for Astrophysics in Cambridge

Far, far away.

The microlensing technique has helped astronomers discover about 30 distant alien planets in our Milky Way’s bulge, the galaxy’s central area of mostly old stars, gas, and dust.

The farthest known exoplanet resides some 25,000 light years away in the bulge of our galaxy, Yee said in the email. The bulge is a very different environment from the Milky Way’s disk, where our own solar system is located.

According to Yee, no exoplanets have been found outside of our galaxy, which spans about 100,000 light years.

Like early explorers mapping the continents of our globe, astronomers are busy charting the spiral structure of our galaxy, the Milky Way. Using infrared images from NASA's Spitzer Space Telescope, scientists have discovered that the Milky Way's elegant s

Comparing planets to planets. Astronomers hope not only to gain a better understanding of the distribution of planets in the Milky Way, but also to gather enough detail about distant planets to compare them with those closer to Earth. More than 1,000 exoplanets closer to home have been discovered by the planet-hunting Kepler mission and ground-based observatories, Space.com reported.

“We would really like to know whether planets form in the central bulge of our galaxy the same way that they do here, near the sun, where the overwhelming majority of planets have been found,” Dr. Andrew Gould, professor of math and physical sciences at Ohio State University, and a co-author of the paper describing the newfound exoplanet, told The Huffington Post.

The Christian Science Monitor reported that the Spitzer telescope is scheduled to observe about 120 more “microlensing” events this summer, which could lead to the discovery of even more distant exoplanets.

NASA’s Dawn Probe Sees Dwarf Planet Ceres as a Crescent


284735main_A-DualAsteroidBelts-full

After spending several weeks in the shadow of Ceres, NASA’s Dawn spacecraft is finally getting a close-up glimpse of the dwarf planet.

For Those Who Don’t Know About CERES : Ceres is the largest object in the asteroid belt, which lies between the orbits of Mars and Jupiter. It is composed of rock and ice, is 950 kilometers (590 miles) in diameter, and comprises approximately one third of the mass of the asteroid belt. It is the only dwarf planet in the inner Solar System and the only object in the asteroid belt known to be unambiguously rounded by its own gravity.

Ceres’ cratered north pole blazes through the darkness in new images captured by Dawn on April 10. The photos are the highest-resolution views of the world that Dawn has gotten since entering Ceres’ orbit on March 6, NASA officials said.

150417-ceres_72b30c3767d128d8e23407c0516ae9f0.nbcnews-ux-1440-800

Dawn was about 21,000 miles (33,000 kilometers) from the dwarf planet when the pictures were taken, and mission team members promise even better views of Ceres in the months to come.

Full science observations begin April 23, when lighting conditions will be better for Dawn and the probe will be even closer to Ceres — just 8,400 miles (13,500 kilometers) above the surface. Dawn will begin moving even lower down on May 9.

In future weeks, NASA hopes the mission will help scientists better understand a key mystery of Ceres: strange bright spots on its surface that, in some cases, have different temperatures than the terrain surrounding them. Mission scientists still don’t know what the spots are made of.

The $466 million Dawn mission, which launched in September 2007, aims to better characterize the solar system’s early days by studying Ceres and Vesta, two intact protoplanets that are the largest denizens of the asteroid belt between Mars and Jupiter. The probe spent 14 months at the 330-mile-wide (530-kilometer-wide) Vesta in 2011 and 2012, then headed to Ceres.

Mission scientists said they expect that Ceres, which is about 590 miles (950 km) wide, will be wetter than Vesta, and made of different stuff. Some researchers think Ceres may even harbor liquid water beneath its surface, perhaps making the dwarf planet capable of hosting life as we know it.

This Is The First Ever Color Picture of Pluto


ESO-L._Calçada_-_Pluto_(by)

New Horizons spacecraft is now only three months away from its historic sweep through the Pluto-Charon system in mid-July. First image in color!

pluto-charon-new-horizons-first-color-pic-April-2015-e1429094950538

NASA’s New Horizons spacecraft acquired its first picture of Pluto and its largest moon, Charon, in color on April 9. It’s the first color image ever made of the Pluto system by a spacecraft on approach. Neither Pluto nor Charon is well resolved here, but their distinctly different appearances can already be seen. Image via NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute.

NASA’s New Horizons spacecraft team released this tantalizing first color image of Pluto and its Texas-sized moon Charon. The team called this image a preliminary reconstruction, which they said will be refined later. The spacecraft acquired the image from a distance of about 71 million miles (115 million kilometers)-roughly the distance from the sun to Venus. New Horizons is now only three months from its historic encounter with Pluto. The flyby through the Pluto system will take place on July 14, at which time the spacecraft will deliver color images that eventually show surface features as small as a few miles across.

New Horizons is the fastest spacecraft ever launched and may be the only spacecraft to sweep past Pluto in our lifetimes. It has traveled a longer time and farther away – more than nine years and three billion miles (4.8 billion km) – than any space mission in history to reach the Pluto system, which consists of the dwarf planet and its five known moons.

NASA pointed out that New Horizons’ flyby of the Pluto system on July 14 will:

… complete the initial reconnaissance of the classical solar system. This mission also opens the door to an entirely new ‘third’ zone of mysterious small planets and planetary building blocks in the Kuiper Belt, a large area with numerous objects beyond Neptune’s orbit.

Principal investigator Alan Stern said the mission would mark the first up-close look at a binary planet. He called Pluto a binary because its large moon Charon is so nearly like Pluto in size.

new-horizons-pluto-doorstep-e1429096387565

Between now and July 14, New Horizons will get closer and closer to Pluto and its moons, and the image quality will rapidly improve. At closest approach, New Horizons will sweep through the Pluto system at a speed of 30,000 mph (50,000 kilometers per hour).

Could we get to Mars in 39 DAYS?


moon-cargo-ship-desktop-wallpaper-1600x1200

Nasa has selected a variety of companies to work on projects to create advanced space technologies, including a faster method of propulsion known as Vasimr (illustrated), which could apparently get to Mars in a matter of weeks, not months

  • Company in Texas has been asked to develop its revolutionary engine
  • Ad Astra’s Vasimr engine could apparently get to Mars in 39 days
  • It is one of 12 advanced technology projects to be funded by Nasa
  • Others include new types of habitation and small deep space satellites

Nasa has selected a variety of companies to work on projects to create advanced space technologies, including faster methods of propulsion.

Other projects to be worked on include improved habitats for humans, and small satellites to explore deep space.

And one of the companies in the 12 Next Space Technologies for Exploration Partnerships (NextStep) says they have an engine that could get humans to Mars in just 39 days.

The Vasimr engine – which uses plasma as a propellant – is being developed by the Ad Astra Rocket company in Texas.

Their engine shot to fame a few years ago when it was revealed that it could drastically reduce the journey time to Mars from months to weeks – although it may require a nuclear power source.

And following the successful test of a prototype in 2013, it seems Nasa is now considering it for use on a future mission to Mars.

If NASA successfully implements this engine then it will truly revolutionize whole Space Frontier. Imagine how easy it will become to explore near earth objects. Moreover, It will help to colonize mars in much faster rate.

China Plans to Build a Solar Power Station in Space


spacestation

China plans to build a huge solar power station 36,000 kilometres above the ground in an attempt to battle smog, cut greenhouse gases and solve energy crisis, much on the lines of an idea first floated in 1941 by fiction writer Isaac Asimov, state media reported today.

If realised, it will surpass the scale of the Apollo project and the International Space Station, and be the largest-ever space project.

The power station would be a super spacecraft on a geosynchronous orbit equipped with huge solar panels. The electricity generated would be converted to microwaves or lasers and transmitted to a collector on Earth, state-run Xinhua news agency reported.

In 1941, American science fiction writer Isaac Asimov had published a short story “Reason”, in which a space station transmits energy collected from the sun using microwave beams.

Wang Xiji, an academician of the Chinese Academy of Sciences and an International Academy of Astronautics member, says Asimov’s fiction has a scientific basis.

After devoting over 50 years to space technology research, Wang, 93, is an advocate for the station: “An economically viable space power station would be really huge, with the total area of the solar panels reaching 5 to 6 sq km.”

That would be equivalent to 12 of Beijing’s Tiananmen Square, the largest public square in the world, or nearly two New York Central Parks. “Maybe people on Earth could see it in the sky at night, like a star,” says Wang.

Wang says the electricity generated from the ground-based solar plants fluctuates with night and day and the weather, but a space generator collects energy 99 per cent of the time.

Space-based solar panels can generate ten times as much electricity as ground-based panels per unit area, says Duan Baoyan, a member of the Chinese Academy of Engineering.

“If we have space solar power technology, hopefully we could solve the energy crisis on Earth,” Duan said.

Wang says whoever obtains the technology first “could occupy the future energy market. So it’s of great strategic significance.”

Countries such as the US and Japan have studied space solar power station. Japan leads the development of wireless power transmission technology. However, many hurdles lie ahead: A commercially viable space power station would weigh 10,000 tons. But few rockets can carry a payload of over 100 tons to low Earth orbit.

This woman wants to live and die on Mars—and 200,000 others would gladly take her place

Dina was born in Iraq, lives in the US, and may end her life on Mars.

She’s one of 663 people who are still in the running for a place on the first four-person team that Mars One, a Dutch organization launched in 2011, wants to send to the red planet. Candidates have been whittled down from some 200,000 who applied.

In a video made for the Guardian by Stateless Media, Dina (whose last name isn’t given) and two other hopefuls—one from the UK, one from Mozambique—discuss love, sex, and death on Mars.

Dina is 29 now, but she’ll be nearing 40 by the time of the Mars mission’s planned launch in 2024. She could be almost a year older than that when they arrive on Mars, which is up to 300 days’ travel away .
Her days may then be numbered. A group of strategic engineering graduates estimated that the first of the travelers would die in 68 days—though the plan is to live there much longer .

Intimacy is not encouraged, because of the potential risks of childbirth—though in the long term the future of colony would rely on it .

No one will return from the mission. This led, last year, to a prohibition on Muslims joining the mission , issued by the General Authority of Islamic Affairs and Endowment in the United Arab Emirates. It judged the mission to be so inevitably fatal that it is essentially suicide.

In the future, the mission plans to meet its costs, to a large extent, via broadcast rights . The first mission will cost $6 billion, according to estimates, though a subsequent mission—a plan is already in the pipeline—would be somewhat cheaper.
