Indian independence, Doppler effect on a train, contagious science

 

By Michael Banks

This week India celebrated 70 years of independence. So what better way to mark the occasion than a music video? Step forward 20 or so scientists from the Indian Space Research Organisation (ISRO), who dub themselves the Rocket Band. Over the space of 18 months, they worked feverishly to create a seven-minute music video entitled “I am an Indian”. Mostly shot on the coast of the Arabian Sea, the video features the researchers walking along the beach as well as an animation of the Indian flag being put on the surface on the Moon. “We have a lot of talent in ISRO, making rockets comes naturally to many of us while making music is tough but it is not rocket science,” aerospace engineer Shiju G Thomas told NDTV.

If you could put anything on a high-altitude balloon, what would it be? World View Enterprises has opted for a spicy chicken sandwich. The company plans to run balloon excursions to the stratosphere and on 21 June it will make its debut voyage carrying a Zinger sandwich from Kentucky Fried Chicken (KFC) – but with no-one on board to eat it. According to the New York Times the flight is tied in with KFC’s current space-based advertising campaign and the sandwich will spend at least four days in the stratosphere. As well as planning to charge tourists $75,000 per person for a ride, World View Enterprises says that its balloons could also be used to create an early warning system for tornadoes. (more…)

We all love a good disaster movie, but when it comes to real life it’s all too easy to downplay a dangerous but distant threat. Many people choose to live on active volcanoes, the citizens of San Francisco know that “the Big One” could strike at any moment, and yet they believe that the benefits of living in those locations outweigh the risk of a severe event happening in their lifetime.

The same dilemma faces the community of scientists, engineers and policy-makers who are working to understand the impacts of space weather – changes in the Earth’s environment that are largely are driven by physical processes originating from the Sun. Space weather has the potential to disrupt or even damage critical infrastructures on Earth, such as the power grids, aviation routes and communication systems that modern societies depend on, but the last notable event dates back to 2003.

That’s why Mike Hapgood, who heads up the Space Weather Group at RAL Space, part of the UK’s Rutherford Appleton Laboratory, has written a new, free-to-read Physics World Discovery ebook called Space Weather. “I thought it would be a great opportunity to highlight what space weather is really about, and to show how we are linking our scientific knowledge to a better understanding of the impacts on society,” he comments.

Create films with the sounds of space

 

By James Dacey

Last weekend I went to a Davie Bowie tribute night at a local pub in Bath. It was a fun evening – roughly a year since the artist passed away – where local musicians played classic tracks by Ziggy Stardust, the Thin White Duke and several of Bowie’s other alter egos. One of the more surreal moments of the night was when a man in a pink suit took to the stage to play what the band called his “spaceship” – producing a whirring, repetitive electronic sound that built up to a crescendo. For a few minutes we were transported into space, just as Bowie intended with many of his memorable songs.

To the stars, through adversity

pwastro16-cover-500By Margaret Harris

Space is, famously, “the final frontier”. It is also – almost as famously – “hard”. We saw this most recently in October, when the Schiaparelli lander crashed onto the surface of Mars, but throughout humanity’s nearly 60-year history as a spacefaring species, our hopes of exploring and observing the cosmos have repeatedly come up against the stiff challenge of building vessels that can survive the journey. Arguably, no other industry on Earth (or indeed off it) has rejoiced in such high “highs”, or agonized through such low “lows”.

That mix of heady dreams and harsh realities is one reason why the latest Physics World focus issue on astronomy and space science carries the tag line “To the stars, through adversity” (I’ll come to the other reason at the end of this blog post). The articles in the issue – which you can read free of charge – pay tribute to the ingenuity of the scientists and engineers involved in the challenging and rewarding practical work of exploring and observing the cosmos. Here, you can learn about the latest advances in astronomical instrumentation, get up to speed with future space missions, and familiarize yourself with recent developments in the entrepreneurial “new space” industry.

Plush toys launched into space, interplanetary mining missions and more

 

By Tushna Commissariat

The European Space Agency’s (ESA) Rosetta spacecraft has, as of this week, spent two full years in orbit around comet 67P/Churyumov–Gerasimenko, since it reached its destination in August 2014. While Rosetta was the mothership, it also deposited its “baby” lander called Philae onto the comet’s surface in November that year. Sadly Philae was switched off in July this year. If you feel like you want to relive the excitement of the initial launch, take a look at the video above. The folks over at Design and Data, who created Rosetta’s iconic cartoons and memorabilia for ESA, launched a plush-toy version of the spacecraft into space, to see how it would fare. Watch the video to see how their “mission” played out.

By Matin Durrani in Beijing, China

I caught up this morning on the second day of my visit to Beijing with Ziyuan Ouyang, chief scientist of China’s Moon programme at the National Astronomical Observatories, which lies not far from the city’s iconic “bird’s-nest” Olympic stadium.

I’d first met Ouyang on my last visit in 2011 when the country had so far launched two lunar missions – Chang’e 1 (which orbited the Moon for 18 months before crash-landing onto the lunar surface) and Chang’e 2 (another lunar orbiter that later moved off into interplanetary space).

China’s lunar efforts have continued and Ouyang explained to me what has happened since my last visit – and what the country plans to do next.

Finding innovation in space

Way to go: Carlton House Terrace. (CC BY-SA 2.0 Richard Croft)

By Margaret Harris

I have a mental block about Carlton House Terrace. This elegant little street in central London is home to several of the UK’s national academies, including the Royal Society and the Royal Academy of Engineering (RAEng), and I’m sure I’ve visited it at least half a dozen times. Yet somehow, whenever I emerge from Charing Cross underground station in the middle of Trafalgar Square, I never know which way to go next.

Fortunately, this is the 21st century, so when the usual disorientation struck me yesterday on my way to an “Innovation in Space” event at the RAEng, I simply pulled out my smartphone. Within seconds, an app told me exactly where I was (plus or minus a few metres) and how to walk from there to 3 Carlton House Terrace. Minutes later, I was safely ensconced in the seminar room, nodding in agreement as the event’s chair, Sir Martin Sweeting, explained how space-related innovations – including, ahem, the network of satellites that make up the Global Positioning System (GPS) – have become an integral part of our daily lives.

Physics World 2015 Focus on Astronomy and Space is out now

By Louise Mayor

PWASTRODec15cover-500Woolly hats are being donned and there’s a nip in the air as the longest night of the year in the Northern hemisphere approaches. All this darkness makes it the perfect season to gaze up at the stars, planets and puffy nebulae above. But binoculars and amateur telescopes can only enhance the view by so much. To really push the boundaries of how far and how fine we can see, we must turn to international telescope projects both on the ground and in space.

To update you on what we think are the most exciting current and future projects we bring you the Physics World Focus on Astronomy and Space, which you can read free of charge in its entirety.

One particularly ambitious imaging effort is described in the article “Portrait of a black hole“, in which Physics World reporter Tushna Commissariat reports on how a group of astronomers plans to take the first-ever image of a black hole. Despite their name, black holes are apparently not black and the Event Horizon Telescope collaboration has already begun pointing a network of ground-based telescopes at its target: Sagittarius A*, the supermassive black hole at the centre of our galaxy.

Heavy-metal Higgs, meet the Publons, Stephen Hawking’s galactic tour and more

By Tushna Commissariat and Hamish Johnston

I’m sure that most of you have wondered what the Higgs boson would sound like if it were a heavy-metal song. Now you can turn it up to 11 (TeV that is) courtesy of CERN physicist and guitarist Piotr Traczyk, who has “sonified” data from two plots from the CMS experiment that were presented at the Higgs discovery seminar on 4 July 2012. His heavy-metal ditty is based on gamma–gamma and 4-lepton data from CMS and after you listen to his excellent song in the above video, you can find out more about how it was created by reading this entry by Traczyk on the Cylindrical Onion blog.
