Space bonanza to land in Manchester

Whatever punters make of the Manchester International Festival (MIF) next year, they certainly won’t be able to accuse it of thinking small. Among the first commissions announced today is a “world-first show about the origin of the universe and everything within and without it”.

The Age of Starlight will be presented by the physicist and TV personality Brian Cox, who will tell the story of the unlikely events that have led to our existence. Details of the show are still scarce but we do know that the space bonanza will feature computer-generated imagery created by the Oscar-winner Tim Webber and the special-effects team behind the film Gravity. The event will be brought to life with technologies developed by Magic Leap, a Florida-based IT company that specializes in “magical” computing solutions.

Candy corn in space, compact fusion reactors and physics in Palestine

 

By Hamish Johnston

Besides the great views of the Earth, one of the best things about being on the International Space Station (ISS) must be messing around in near-zero gravity. In the above video on Science Friday the American astronaut Don Pettit describes an “experiment” that he did on the ISS using candy corn, which are kernel-like sweets. He begins with a blob of floating water into which he inserts the candy corn pointy-end first. The points are hydrophilic so they tend to stay in the water, and eventually Pettit has a sphere of candy corn packed around the water. The flat ends of the candy corn have been soaked in oil to make them hydrophobic so the candy corn layer acts like a detergent film or one half of a cell membrane. It’s a fun video and I wonder how he got the idea in the first place?

Food for Martian thought, proton role-playing in a video game and more

By Tushna Commissariat

With space agencies across the world planning manned missions to Mars in the coming decades, pondering what one would eat while on Mars seems like a sensible thing to do. SpaceX engineer Andrew Rader helps us out with this difficult question in the video above, sharing gems like “chickens can’t swallow in space.” In the video, titled “Cooking on Mars” Rader cooks and eats a seemingly unappetizing option – bugs and insects – and makes it clear that is the fare future astronauts will be partaking in.

Yeah but no but yeah but no but…

Has the Voyager spacecraft left the solar system and entered interstellar space? I don’t know about you, but I’m getting a teensy weensy bit bored by this question, which has been going on for years now.

Last September, we blogged about a paper in Science that, yep, it had definitely left the solar system a year before – on 25 August 2012 in fact.

Previous to that, though, there had been other reports that no it hadn’t (June 2013), it really, definitely is getting near the edge, but hang on actually not yet (March 2013), we’re not quite sure (June 2011), of course it’s definitely heading for interstellar space (November 2009), it’s already right near the edge (or possibly not) (November 2003).

Meeting the last man to walk on the Moon

Eugene Cernan speaking at Sheffield Doc/Fest.

By James Dacey, reporting from Sheffield

“I wanted to make a film about an old space cowboy” is how British director Mark Craig introduced his new film on Sunday afternoon here at Sheffield Doc/Fest. The Last Man on the Moon takes a fresh look at the the Apollo era through the story of Eugene Cernan, who was the last person to set foot on the lunar surface when he did so in 1972 as commander of Apollo 17.

The documentary interleaves a profile of “Gene” Cernan with NASA archive footage and special effects, focusing on the personal stories of the astronauts and their families. To give you a flavour, the film opens in the present day with close-ups of Cernan’s facial reactions at a rodeo event as he admires the spectacle and the bravery of the men being thrown around on the back of bulls. Later in the film, Cernan recounts his experiences of being rotated rapidly in space during the Gemini 9A and Apollo 10 missions.

Immediately after the showing, Cernan and Craig stayed for a Q&A session and the audience gave an extended standing ovation as the 80-year-old astronaut walked to the front of the auditorium. I was fortunate to catch up with the pair this morning to get some insights into the inspiration for the film and how it was adapted from the book Cernan co-authored in 1999.

Spacecraft duets, suprise supernovae, the dark side of physics and more

By Tushna Commissariat

While you would not actually be able to hear the uplifting notes of the music in the vast emptiness of space, a newly composed string and piano orchestral piece has unexpected ties to the cosmos. That’s because it is based on 36 years’ worth of data from NASA’s Voyager 1 and 2 spacecraft. Domenico Vicinanza, a trained musician with a PhD in physics who works at GÉANT, a European data-network company, says that he “wanted to compose a musical piece celebrating Voyager 1 and 2 together, so I used the same measurements (proton counts from the cosmic-ray detector over the last 37 years) from both spacecrafts, at the exactly same point in time, but at several billions of kilometres of distance [of] one from the other”. The result of this “data sonification” is a rather beautiful piece of music – one of the best examples of physics and the arts coming together that we have heard. Of course, the story garnered considerable interest…you can read more about on the Wired and Guardian websites.

Cress on the Moon, more physics books, a radioactive ‘foot’ and more

Early this week, a story in the Telegraph caught our eye – NASA is planning on sending turnip, cress and basil seeds to the Moon to germinate them! This is most definitely not the first time that plants have been grown beyond the realms of Earth. Indeed, potatoes were grown on board during a 1995 Space Shuttle mission and many experiments involving germinating seeds were done on the International Space Station. The goal of these studies was to understand the effects of microgravity on plant growth. But now, NASA plans to take this one step further in 2015 with their Moon Express mission, which will include the Lunar Plant Growth Chamber that will carry seeds and enough air and nutrients to allow the seeds to sprout and grow. Will fresh salad be on an astronaut’s menu soon?

Herschel in a minute

By Michael Banks

Here is an example of how to condense four years’ worth of space observations into just a minute.

The animation above, which was created by Pedro Gómez-Alvarez of the European Space Agency (ESA), shows a timeline of more than 37,000 scientific observations made by ESA’s Herschel Space Observatory.

The video runs from Herschel’s launch on 14 May 2009 until the infrared observatory made its last observation on 29 April 2013 as the craft’s detectors ran out of coolant.

Herschel – a far-infrared and submillimetre telescope – had two main goals: to study star formation in our galaxy; and galaxy formation across the universe.

Named after the German-born astronomer who in 1781 discovered Uranus, the probe carried a 3.5 m-diameter mirror – the largest to be deployed in space – and investigated light with wavelengths of 55–670 µm.

The craft was placed in an area of space some 1.5 million kilometres further out from the Sun beyond the Earth. Known as Lagrange point L2, it is where a space probe can usefully hover, little disturbed by stray signals from home and without having to use much fuel to keep it in position.

You can find some of the incredible images taken by Herschel at ESA’s multimedia gallery.

Voyager 1: a peer-reviewed day to remember

By Hamish Johnston

Yesterday a paper appeared in Science that makes the case that the Voyager 1 spacecraft has left the solar system. The response from the press and commenters has been to declare this a day to remember. Indeed, some have likened it to 20 July 1969 when Neil Armstrong first stepped on the Moon.

Vintage snaps from space history

If you look incredibly closely you may just be able to make out John Lennon’s flares or the England football team lifting the World Cup. This portrait of our planet from 1966 is part of the first collection of photos of the Earth taken from beyond the Moon. It was taken by a camera on board Lunar Orbiter I, the first US spacecraft to orbit the Moon, which helped pave the way for the Moon landings at the end of the decade.
