SpaceX’s rocket just exploded. Here’s why that’s such a big deal.

An unmanned SpaceX Falcon 9 rocket bound for the International Space Station exploded a couple of minutes after liftoff Sunday morning. It was the third cargo mission to the space station to be lost in recent months.

Elon Musk, SpaceX’s founder tweeted that “there was an overpressure event in the upper stage liquid oxygen tank.” He added: “That’s all we can say with confidence right now. Will have more to say following a thorough” analysis.

NASA officials said it was not clear what caused the explosion. During an afternoon press conference William Gerstenmaier, NASA’s associate administrator for human exploration and operations, said there was “no negligence here.”

The three failures from three different launch providers show “the challenges facing engineering and the challenges facing space flight in general.”

The rocket took off from Cape Canaveral, Fla., at 10:21 a.m., and everything seemed fine until 2 minutes at 19 seconds. Then video of the launch showed harrowing, if now familiar, images of a rocket exploding into a plume of smoke. The Falcon 9 was carrying more than 4,000 pounds of food and supplies to the space station, where American Scott Kelly is spending a year. There were no astronauts onboard.

The explosion also lost many student experiments and a water filtration system. Also onboard was a piece of hardware that would be used to help two new crew vehicles dock to the station.

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).

Our star is five billion years younger than most in the Milky Way


19091-milky-way-above-the-canyon-1680x1050-nature-wallpaper

Our sun is nearly 4.5 billion years — which means it missed the charming initial years of the Milky Way galaxy. If you were standing on a planet nearly about 10 billion years ago, when the Milky Way was pretty young, the night sky would have appeared very different. The image below is an artist’s impression of the night sky on a planet in a relatively young Milky Way-type galaxy, the way our galaxy was 10 billion years ago. You can see “the sky are ablaze with star birth. Pink clouds of gas harbor newborn stars, and bluish-white, young star clusters litter the landscape,” as NASA explains.

A recent study of young galaxies like our own demonstrates that as these galaxies slow down creating stars, they also stop developing as quickly in general. Which is quite logical. NASA explains:

“Astronomers don’t have baby pictures of our Milky Way’s formative years to trace the history of stellar growth so they studied galaxies similar in mass to our Milky Way, found in deep surveys of the universe. The farther into the universe astronomers look, the further back in time they are seeing, because starlight from long ago is just arriving at Earth now. From those surveys, stretching back in time more than 10 billion years, researchers assembled an album of images containing nearly 2,000 snapshots of Milky Way-like galaxies. The new census provides the most complete picture yet of how galaxies like the Milky Way grew over the past 10 billion years into today’s majestic spiral galaxies. The multi-wavelength study spans ultraviolet to far-infrared light, combining observations from NASA’s Hubble and Spitzer space telescopes, the European Space Agency’s Herschel Space Observatory, and ground-based telescopes, including the Magellan Baade Telescope at the Las Campanas Observatory in Chile.”

NASA is working with Russia on a new space station


STS-116_spacewalk_1

Astronauts Repairing Space Module

Russia is teaming up with the USA to build ISS 2.0 once the current one’s funding runs out in 2024 — at least according to Russia Today and state news agency TASS. The country’s space agency, Roscosmos threatened in February to use the Russian ISS modules as a platform for a new base of its own after 2024, but now it looks like there will be a followup collaboration.

This time around, both parties are looking for participation from other countries, as well as private industry, and are apparently even eyeing a team-up for potential missions to Mars. Russian news outlets report the announcement came during a news conference Saturday following the launch of a year-long mission (video of the launch and subsequent ISS docking is embedded after the break) to the current International Space Station.

NASA Statement –

We are pleased Roscomos wants to continue full use of the International Space Station through 2024 — a priority of ours — and expressed interest in continuing international cooperation for human space exploration beyond that. The United States is planning to lead a human mission to Mars in the 2030s, and we have advanced that effort farther than at any point in NASA’s history. We welcome international support for this ambitious undertaking. Today we remain focused on full use of our current science laboratory in orbit and research from the exciting one-year mission astronaut Scott Kelly just began, which will help prepare us for longer duration spaceflight.

Chief Komarov, who was there for the US-Russia year-long ISS mission launch, reportedly said: “We have agreed that Roscosmos and NASA will be working together on the program of a future space station.” In addition to building a new ISS, sources say the agency’s partnership also entail working on a joint Mars mission. In the same event, NASA chief Charles Bolden is quoted saying: “Our area of cooperation will be Mars. We are discussing how best to use the resources, the finance, we are setting time frames and distributing efforts in order to avoid duplication.”

So far NASA hasn’t announced or confirmed anything through its official channels. We’ve contacted the agency for comment and will update this post if we hear anything.

A ginormous asteroid is headed our way, but no need to worry. NASA says asteroid 2004 BL86–estimated to be about one-third of a mile in diameter–will zoom harmlessly by Earth later this month.

That’s good news, of course. And get this: The asteroid’s size and proximity–about 745,000 miles from Earth at the nearest point in its flyby, or about three times the distance from the Earth to the Moon–mean it should be visible with nothing more than a good pair of binoculars.

nearearthasteroid

“Monday, January 26 will be the closest asteroid 2004 BL86 will get to Earth for at least the next 200 years,” Don Yeomans, manager of NASA’s Near Earth Object Program Office at the Jet Propulsion Lab, said in a written statement. “And while it poses no threat to Earth for the foreseeable future, it’s a relatively close approach by a relatively large asteroid, so it provides us a unique opportunity to observe and learn more.”

Skywatchers in the Americas, Europe, and Africa should have the best view of the asteroid on the night of Jan. 26, according to EarthSky. Weather permitting, the asteroid should be visible moving slowly across the sky in the vicinity of the constellation Cancer.

Of course, it will only look slow. The asteroid is actually streaking at about 35,000 miles an hour.

Yeomans said he might grab his own binoculars and have a look himself. If you’d rather stay indoors, you can catch the action online at The Virtual Telescope Project 2.0. The show starts at 2:30 p.m. EST.

Nasa’s Kepler Discovers Star With 3 Planets Larger Than Earth

Nasa’s Kepler space telescope has discovered a star with three planets only slightly larger than Earth.

The star, EPIC 201367065, is a cool red M-dwarf about half the size and mass of our own Sun.

At a distance of 150 light years, the star ranks among the top 10 nearest stars known to have transiting planets.

“A thin atmosphere made of nitrogen and oxygen has allowed life to thrive on Earth. But nature is full of surprises. Many exoplanets discovered by the Kepler mission are enveloped by thick, hydrogen-rich atmospheres that are probably incompatible with life as we know it,” said Ian Crossfield, the University of Arizona astronomer who led the study.

“Most planets we have found to date are scorched. This system is the closest star with lukewarm transiting planets,” added University of California Berkeley graduate student Erik Petigura.

Petigura discovered the planets January 6 while conducting a computer analysis of the Kepler data NASA has made available to astronomers.

“There is a very real possibility that the outermost planet is rocky like Earth, which means this planet could have the right temperature to support liquid water oceans,” he noted.

After Petigura found the planets in the Kepler light curves, the team quickly employed telescopes in Chile, Hawaii and California to characterise the star’s mass, radius, temperature and age.

The star’s proximity means it is bright enough for astronomers to study the planets’ atmospheres to determine whether they are like the Earth’s atmosphere and possibly conducive to life.

The next step will be observations with other telescopes, including the Hubble Space Telescope, to take the spectroscopic fingerprint of the molecules in the planetary atmospheres.

“If these warm, nearly Earth-size planets have puffy, hydrogen-rich atmospheres, Hubble will see the telltale signal,” Petigura said.

The paper has been submitted to Astrophysical Journal and is freely available on the arXiv website.

NASA Begins Countdown to Pluto Flyby


NEW-HORIZONS-ALEX-PARKER

An artist’s impression of NASA’s New Horizons spacecraft, currently en route to Pluto; after nine years and a journey of 3 billion miles, NASA’s New Horizons robotic probe will be woken from hibernation to begin its unprecedented mission: the study of the icy dwarf planet Pluto and its home, the Kuiper Belt.

Today marks the beginning of the world’s encounter with Pluto, as a NASA spacecraft that has journeyed for nine years begins its first phrase of approach to the dwarf planet.

The spacecraft is still 135 million miles away from Pluto, but Thursday marks a significant day for NASA scientists as the beginning of a series of phases in which the spacecraft can start studying and capturing increasingly detailed images of the Pluto system.

In just under six months, the world will catches its first close-up glimpse of Pluto when NASA’s New Horizons zooms within 6,200 miles of the dwarf planet on July 14.

New Horizons has traveled three billion miles since its launch on January 19, 2006, according to NASA. That’s farther than any other other space exploration mission has ever gone to reach its primary target.

As with space missions before it, the New Horizons spacecraft is packed with interesting memorabilia, including two U.S. flags and some of the ashes of Clyde Tombaugh, the American astronomer who discovered Pluto in 1930.

The spacecraft has spent about two-thirds of the time since its launch (intermittently) “in hibernation” in order to reduce the wear and tear on equipment and minimize the risk of system failures. But on December 6 last year, the spacecraft came out of hibernation and switched into active mode for its final approach.

In honor of the Huygens probe’s historic 2005 landing on the surface of Titan (Saturn’s largest satellite, and the only moon in our solar system with a dense atmosphere), NASA has released a movie that recreates, with data collected by Huygens and the Cassini orbiter, a dramatic approach of the moon’s surface from deep space.

The descent on 15 January 2005 lasted a total of two hours, with Huygens landing on a frigid floodplain surrounded by icy cobblestones.

It is the only landing that has ever been performed in the outer solar system to date, and one of only a handful of bodies – the others being Venus, Mars, the moon, two asteroids and most recently a comet – that manmade probes have ever landed on.

On the surface the probe continued to send back data for more than an hour, until its batteries were drained.

Since that historic moment, scientists have pored over volumes of data about Titan sent back to Earth.

Hubble captures the sharpest ever view of neighbouring spiral Galaxy


Sharpest ever view of the Andromeda Galaxy

The NASA/ESA Hubble Space Telescope has captured the sharpest and biggest image ever taken of the Andromeda galaxy — otherwise known as Messier 31. The enormous image is the biggest Hubble image ever released and shows over 100 million stars and thousands of star clusters embedded in a section of the galaxy’s pancake-shaped disc stretching across over 40 000 light-years.

This sweeping view shows one third of our galactic neighbour, the Andromeda Galaxy, with stunning clarity. The panoramic image has a staggering 1.5 billion pixels — meaning you would need more than 600 HD television screens to display the whole image . It traces the galaxy from its central galactic bulge on the left, where stars are densely packed together, across lanes of stars and dust to the sparser outskirts of its outer disc on the right.

The large groups of blue stars in the galaxy indicate the locations of star clusters and star-forming regions in the spiral arms, whilst the dark silhouettes of obscured regions trace out complex dust structures. Underlying the entire galaxy is a smooth distribution of cooler red stars that trace Andromeda’s evolution over billions of years.

The Andromeda Galaxy is a large spiral galaxy — a galaxy type home to the majority of the stars in the Universe — and this detailed view, which captures over 100 million stars, represents a new benchmark for precision studies of this galaxy type . The clarity of these observations will help astronomers to interpret the light from the many galaxies that have a similar structure but lie much further away.

Because the Andromeda Galaxy is only 2.5 million light-years from Earth it is a much bigger target on the sky than the galaxies Hubble routinely photographs that are billions of light-years away. In fact its full diameter on the night sky is six times that of the full Moon. To capture the large portion of the galaxy seen here — over 40 000 light-years across — Hubble took 411 images which have been assembled into a mosaic image.

This panorama is the product of the Panchromatic Hubble Andromeda Treasury
(PHAT) programme. Images were obtained from viewing the galaxy in near-ultraviolet, visible, and near-infrared wavelengths, using the Advanced Camera for Surveys aboard Hubble. This view shows the galaxy in its natural visible-light colour as photographed in red and blue filters.

This image is too large to be easily displayed at full resolution and is best appreciated using the zoom tool.

The image was presented today at the 225th meeting of the American Astronomical Society in Seattle, Washington, USA.
