Scientists battle celebrities, a quantum ‘unconference’ and space travel, past and future

 

By Tushna Commissariat

Its been a strange week for scientists and celebrities popping up together on the world stage – what with rapper B.o.B and Neil deGrasse Tyson’s very public face-off about the former’s conspiracy theory claims of the Earth being flat  – but it didn’t end there. In a celebrity trio that is even more surprising, physicist Stephen Hawking has come together with Hollywood actor Paul Rudd, (most recently starring in the film Ant-Man) in a video narrated by Keanu Reeves. Earlier this week, Caltech’s Institute for Quantum Information and Matter hosted the event One Entangled Evening: a Celebration of Richard Feynman’s Legacy. As a promo of sorts for the event – which had special appearances by Rudd, Reeves, Hawking, Bill Gates and even Yuri Milner, apart from actual quantum physicists such as John Preskill and Dave Wineland – they filmed the above video with Rudd and Hawking battling each other at a game of quantum chess. You will have to watch the video to see who wins.

Preserving Apollo’s data legacy

Day two of AGU Fall 2015 saw the likes of SpaceX CEO Elon Musk and NSF director France Córdova talking in rooms packed full of earth and space scientists. But what grabbed my attention was a short talk by Nancy Todd of NASA’s Astromaterials Acquisition and Curation Office.

NASA being NASA, I assumed that all its data from completed missions would by now have been digitized and made accessible. That, I learned, is not true – but Todd and her colleagues are on the case.

Pushing towards the human–Martian frontier

Last week, the planet Mars was under the international spotlight once more as NASA scientists announced that liquid water may still be flowing on the surface of the red planet. Also, the much-anticipated film adaptation of The Martian – a 2011 novel by American author Andy Weir a science-driven story of human survival on Mars, hit the box office.  Mars was also the hot topic at a recent event held at the National Space Centre in Leicester. The guest of honour was Apollo 7 astronaut Walter Cunningham and throughout the hour-long Q&A, he emphasized the need to push the “next frontier” and send humans to Mars.

Cunningham is not a man lacking in confidence or the experience of pushing boundaries. When asked if he ever felt the pressure of the astronaut selection or training process, he said “I thought I could fly anything, any time, anywhere. Was that true? I don’t know. But that’s how I felt.”

Florida’s declining Space Coast, naming mountains on Pluto and silly rock bands

By Hamish Johnston

When I was a young lad back in the late 1960s, my family would join the annual March migration of Canadians to Florida. Along with alligator farms and the endless beaches, the Kennedy Space Center was a popular tourist destination and I can still remember visiting it and getting a solar spinner globe as a souvenir. Sadly, since the end of the Space Shuttle programme in 2011, Florida’s “Space Coast” has fallen on hard times. While there are still rocket launches – there are two planned for April – thousands of NASA employees have been let go and the surrounding communities look worse for wear. The New York-based photographer Rob Stephenson has put together a collection of images taken in and around the centre that he calls “Myths of the Near Future”. To me the photographs evoke the allure of the space age as well as the inevitable decline of any human endeavour.

Homework help from NASA, rescue missions, top technologies and more

By Tushna Commissariat

Who doesn’t like a bit of help with their homework – not 4-year-old Lucas Whiteley from West Yorkshire in the UK.  When faced with some tough and rather complex scientific questions, the enterprising child filmed a video of himself asking the US space agency NASA for some help. And much to his delight, he got a video response courtesy of NASA engineer Ted Garbeff of the Ames Research Center in California. In the 10-minute video, Garbeff answers Whiteley’s questions including “How many stars are there?” and “Did any animals go to the Moon?” Of course, the story garnered nation-wide interest and was covered by the Huffington Post, the Telegraph and others. Take a look at Garbeff’s response video above.

Exoplanets are everywhere

Just a few years ago the idea that more than 700 exoplanets could be discovered in a single study would seem fantastical. But that’s exactly what astronomers working on NASA’s Kepler mission have just done.

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?

The best thing about science fiction is that it is fiction, and nit-picking about scientific accuracy shouldn’t get in the way of telling a good story. That’s the theme of Roger Highfield’s review of the latest blockbuster Gravity. Writing in his old paper The Daily Telegraph, Highfield – who now works at London’s Science Museum – takes exception to a series of Tweets by the celebrity astrophysicist Neil deGrasse Tyson about the film. Among other things, the Tweets complain that Sandra Bullock’s hair should be wafting around in zero gravity, not hanging down as it would on Earth. Despite these and other “scientific holes big enough to fly a Saturn V rocket through” both Highfield and Tyson agree that Gravity is a film well worth seeing. The review is called “Gravity: how real is the science?“.

NASA badly hit by government shutdown

By James Dacey

US citizens woke up this morning to the unbelievable news that their federal government would be shutting down all its “non-essential” services after the two houses of Congress failed to reach an agreement on a new budget. What this means in practice is that hundreds of thousands of federal employees will now face unpaid leave – and NASA’s workforce is among the most badly affected.

A staggering 97% of NASA’s 18,134 employees have been granted leave of absence, according to the Office of Management and Budget, quoted in the New York Times. This is the highest percentage of all the federal departments and agencies to be affected by the shutdown. Other federal workers affected include 94% of the 16,205 employees of the Environmental Protection Agency, along with 69% of the 13,814 working within energy.

“Due to the gov’t shutdown, all public NASA activities/events are cancelled or postponed until further notice. Sorry for the inconvenience,” read a rather understated tweet from NASA earlier today. Within the past few hours, the NASA website has also shutdown indefinitely.

NASA asked, so we waved at Saturn

On 19 July the Cassini spacecraft turned back to face Earth from its location by Saturn and captured this humbling photo of our planet as a tiny dot behind Saturn’s rings. As part of the event, NASA encouraged people to snap pictures of themselves waving at Venus and to share these via social-media sites. Now, 1400 of these images have been used to create this collage, which includes people from more than 40 countries and 30 US states.

“While Earth is too small in the images Cassini obtained to distinguish any individual human beings, the mission has put together this collage so that we can celebrate all your waving hands, uplifted paws, smiling faces and artwork,” says Linda Spilker, Cassini project scientist at NASA’s Jet Propulsion Laboratory in California.

NASA has, however, released a larger version of the “Wave at Saturn” collage where you can zoom in to make out individual images. It is well worth doing so, as you quickly come across the whole spectrum of gestures from the gentle wave to the Vulcan salute.
