Space Exploration Day - 20th Jul, 2015

The origins of Space Exploration Day date back to man first walking on the moon, with the day itself first observed to commemorate this historic event during events held in the early 1970s.

It’s been a long time, but SpaceX lost a cargo-carrying rocket today.

SpaceX launch web cast. Although it’s not clear what happened, the rocket blew up 2 minutes and 19 seconds into its launch this morning (see below). Elon Musk, the company’s founder, said the problem occurred shortly before the rocket’s first stage shut down. Later, he added, “There was an overpressure event in the upper stage liquid oxygen tank.”

No humans were on board but the spacecraft was carrying 4,000 pounds worth of supplies to the International Space Station.

Mystery Mars plume baffles scientists Mystery plume on Mars 16 February 2015 Plumes seen reaching high above the surface of Mars are causing a stir among scientists studying the atmosphere on the Red Planet.

Mystery Mars plume baffles scientists

On two separate occasions in March and April 2012, amateur astronomers reported definite plume-like features developing on the planet. The plumes were seen rising to altitudes of over 250 km above the same region of Mars on both occasions. Maxime Duprez sur Twitter : "#Space: a new way to view #Saturn's satellite #Titan: 'despeckle' it! ► via @physorg_com. A new way to view Titan: 'Despeckle' it. During 10 years of discovery, NASA's Cassini spacecraft has pulled back the smoggy veil that obscures the surface of Titan, Saturn's largest moon.

A new way to view Titan: 'Despeckle' it

Cassini's radar instrument has mapped almost half of the giant moon's surface; revealed vast, desert-like expanses of sand dunes; and plumbed the depths of expansive hydrocarbon seas. What could make that scientific bounty even more amazing? Well, what if the radar images could look even better? Thanks to a recently developed technique for handling noise in Cassini's radar images, these views now have a whole new look. The technique, referred to by its developers as "despeckling," produces images of Titan's surface that are much clearer and easier to look at than the views to which scientists and the public have grown accustomed.

Typically, Cassini's radar images have a characteristic grainy appearance. "Noise in the images gave me headaches," said Lucas, who now works at the astrophysics division of France's nuclear center (CEA).

That's how long it takes a signal to travel the 500 million kilometres from the surface of comet 67P Churyumov-Gerasimenko to the European Space Agency's mission control in Darmstadt, Germany. So that's how long Taylor must wait to find out if his team has made history by landing a spacecraft on a comet for the very first time. The European Space Agency (ESA) craft, Rosetta, has been orbiting comet 67P since August.

Plenty could go wrong. There is a great deal we want to find out about 67P. Comets are often called dirty snowballs. - Is there an end? by RMirandinha on deviantART.

How Many Moons Does Saturn Have?

Credit: NASA/JPL/Space Science Institute Saturn’s moons have such a variety of environments between them that you’d be forgiven for wanting to spend an entire mission just looking at its satellites. From the orangy, hazy Titan to the icy plumes emanating from Enceladus, studying Saturn’s system gives us plenty of things to think about. Not only that, the moon discoveries keep on coming. As of April 2014, there are 62 known satellites of Saturn (excluding its spectacular rings, of course). Most of these moons are pretty small ones, just a few miles across, but on the other hand there are larger ones such as the moon Titan.

Ice-capades: The true blue beauty of the icebergs of Iceland. By Sara Malm Published: 16:56 GMT, 12 November 2012 | Updated: 20:17 GMT, 12 November 2012 It has been called the nation of fire and ice and as these stunning pictures proves, it is certainly the latter.

The magnificent ever-changing landscapes of Iceland where the freezing temperatures make the icebergs and glaciers shift in every shade of blue, from turquoise and azure to indigo. Spiral Galaxy Messier 83* This dramatic image of the galaxy Messier 83 was captured by the Wide Field Imager at ESO's La Silla Observatory, located high in the dry desert mountains of the Chilean Atacama Desert.

Spiral Galaxy Messier 83*

Messier 83 lies roughly 15 million light-years away towards the huge southern constellation of Hydra (the sea serpent). It stretches over 40 000 light-years, making it roughly 2.5 times smaller than our own Milky Way. However, in some respects, Messier 83 is quite similar to our own galaxy. Amazing Photos: Jupiter's Volcanic Moon Io. Astrophysics: Fire in the hole! Andy Potts In March 2012, Joseph Polchinski began to contemplate suicide — at least in mathematical form.

Astrophysics: Fire in the hole!

A string theorist at the Kavli Institute for Theoretical Physics in Santa Barbara, California, Polchinski was pondering what would happen to an astronaut who dived into a black hole. Obviously, he would die. But how? According to the then-accepted account, he wouldn’t feel anything special at first, even when his fall took him through the black hole’s event horizon: the invisible boundary beyond which nothing can escape. But Polchinski’s calculations, carried out with two of his students — Ahmed Almheiri and James Sully — and fellow string theorist Donald Marolf at the University of California, Santa Barbara (UCSB), were telling a different story1.
