Show home for the Red Planet

Mars show home at the Royal Observatory Greenwich, London.

A big red igloo with a towering antenna seems a little overblown for a London show home. And so it proves. The object squatting outside the Royal Observatory Greenwich is actually a life-sized mock-up of a Mars habitat, billed as the imaginary dwelling of a second wave of settlers from Earth. That is, those who might live on the Red Planet in their thousands by around 2037, if the ambitious plans of space entrepreneurs such as SpaceX’s Elon Musk bear fruit.  Read more

The art of engineering: 9 Evenings revisited

The art of engineering: 9 Evenings revisited

I’m gazing at a stage draped in white when a giant zipper suddenly appears, projected onto one wall. As it works its way noisily around, more projections — live-streamed or pre-recorded moving images of buildings, blurred pedestrians, discarded clothing and simmering water — judder on crumpled backdrops. An apparently random urban soundtrack lulls and roars in the background. In the foreground, performers skip rope and cut hair; one solemnly rips up, boils and eats her shirt. It’s quite an evening.  Read more

Smoke on the water

Smoke on the water

Nobody loves disasters more than movie producers. If threats in real life matched their frequency on screen, we should be in a constant state of panic over the risks of alien invasions, zombie viruses and asteroid impacts. Given the film industry’s appetite for catastrophes, it is no surprise that it has finally focused on the greatest environmental disaster in US history: the 2010 oil spill in the Gulf of Mexico that began with explosions that killed 11 people and sank the Deepwater Horizon drilling rig.  Read more

Breaking barriers: the US space programme’s black women mathematicians

Breaking barriers: the US space programme's black women mathematicians

Some of the most intriguing stories in the history of US science have emerged over the past few years. It’s about time. These books centre on something long under wraps: the centrally important roles women played starting some 70 years ago in the great technological transition that gripped the twentieth century. Denise Kiernan’s The Girls of Atomic City (Touchstone, 2013) chronicled the contributions of the women who worked at the secret atomic-bomb laboratory in Oak Ridge, Tennessee, during the Second World War. Rise of the Rocket Girls by Nathalia Holt (reviewed here) depicted the mathematicians or “human computers” who crunched numbers at the Jet Propulsion Laboratory in southern California from the 1940s. In this catalogue, Margot Lee Shetterly’s Hidden Figures is more than just another entry.  Read more

The Hubble ‘space opera’

Hubble image of the Orion Nebula, at 1,500 light-years away, the nearest star-forming region to Earth. The bright glow at upper left is from M43, a small region being shaped by a massive, young star's ultraviolet light.

In 2012, composer Paola Prestini began collaborating with astrophysicist Mario Livio — who worked at the Hubble Space Telescope’s operations centre from 1991 to 2015 — on a “space opera” celebrating the intrument’s 25th anniversary. The result, The Hubble Cantata, debuted on the telescope’s 26th. Performed on 6 August at the BRIC Celebrate Brooklyn! festival in New York City’s Prospect Park, it is a multidimensional paean to the ‘eye in the sky’, meshing Livio’s narration with performances by Norwegian orchestra 1B1, a 100-strong chorus and Metropolitan opera stars Jessica Rivera and Nathan Gunn, and a climax featuring a 3D virtual-reality (VR) experience incorporating Hubble images that allows viewers to drift through the Orion Nebula. Here Prestini talks about the joys and challenges of putting together a highly collaborative meld of science and art.  Read more

Reflections of a Moonwalker

Reflections of a Moonwalker

The Moon landings – those grainy shots of men in bulky suits and stunning visions of Earthrise – have burned into the public consciousness for half a century. But to those who weren’t there to watch it live and who have seen human space travel since confined to Earth’s orbit, walking on the Moon seems like a distant fairytale (a fact that no doubt contributes to the conspiracy theory that it never happened).  Read more

Share the repair

Share the repair

A few decades ago, a broken radio, fan or kettle generally triggered a trip to the repair shop. Now, it often means a journey to the dump. In Britain alone each year, over 2 million tonnes of waste electrical and electronic equipment are discarded; in Europe and the United States, repair services have been in decline for some decades. This ‘take, make and dispose’ approach sits uncomfortably with shifts towards closed-loop thinking and policy, such as the European Commission (EC) package on the circular economy, which emphasises repair, recycling and reuse.  Read more

The making of Alice

The making of Alice

On 19 October 1863 an unknown mathematician, Charles L. Dodgson, was introduced to the publisher Alexander Macmillan in Oxford by Thomas Combe, director of the Clarendon Press and printer to Oxford University. Macmillan’s publishing business, established with his brother in 1843, was growing. He had built a reputation among scholars and authors as a leading academic publisher in fields such as mathematics and geology.  Read more
