Japan readies space probe for mission to chase asteroid and shoot it with a cannon

Following on from the mixed success of the ambitious Hayabusa-1 mission, Japanese space scientists are almost ready to try again at hunting an asteroid.

While most of the headlines may be going to the European Space Agency's Rosetta probe right now - it being the first craft to enter into orbit around a comet - there are some other impressive space missions in the pipeline which shouldn't be forgotten. One of these was unveiled this week by the Japanese space agency, Jaxa - the asteroid-hunting Hayabusa-2 probe.

When Hayabusa-2 launches in November or December of this year it will begin a near-four year voyage to asteroid 1999 JU3, where it will then spend 18 months surveying the surface and running a series of experiments. By far the most audacious of these will be the "explosively-formed penetrator", which is a sciencey way of saying that missions planners are going to fire a 30cm copper ball from an on-board cannon at the asteroid's surface. The "bullet" is planned to have a relative velocity of roughly 2km/s, or around six times faster than a bullet travels when fired from a handgun - though this explanatory video from Jaxa appears somewhat lethargic by comparison:

The reason scientists want to shoot an asteroid is quite simple - dust from the crater the bullet leaves will reach escape velocity, creating a cloud of debris that Hayabusa-2 can then float through and collect samples from. (Though, just to be safe, the probe will sneak around to the other side of the asteroid in the time it takes for the bullet to reach the surface, just to avoid any debris that comes up at a dangerous speed.) Hayabusa-2 will then return to Earth by 2020, where that dust - containing, it is hoped, carbon, water and other minerals - will be studied for clues as to the nature of the early Solar System, and how life on Earth may have originated.

Besides the cannon, Hayabusa-2 will also carry four different landers. One, the Mobile Asteroid Surface Scout (Mascot), has been built by the French and German space agencies, is essentially a small laboratory in a box which will be able to take measurements of the conditions on the asteroid's surface for 16 hours after landing. Rather wonderfully, it will be able to "hop" twice using small feet before its batteries run out, tripling the positions on the asteroid's surface it can gather data from. Hayabusa-2 will also carry three Micro/Nano Experimental Robot Vehicle for Asteroid (Minerva-II) landers, more primitive rovers that should also hop languidly across the asteroid's surface, beaming back video footage to Earth and taking measurements. There's something quite beautiful about the idea of a quartet of bouncing robots exploring the surface of a tiny alien world.

In this sense Hayabusa-2 is a bigger, more ambitious version of Hayabusa-1, which only carried one Minerva rover when it arrived at the asteroid Itokawa in 2005. That mission was the first to rendezvous with an asteroid, land, collect samples and then return to Earth, but it was a mission threatened multiple times with failure. Budget cuts pushed back its launch and meant that Nasa couldn't provide it with a lander, a solar flare damaged its solar panels, internal mechanical faults threatened its ability to steer, and at several points scientists lost contact with it. It very nearly didn't have the ability to return to Earth, and, perhaps most tragically, its Minerva hopper was released at the wrong time - it missed the asteroid, floating away into space.

However, the samples that Hayabusa-1 did manage to retrieve were of immense scientific importance (once they'd been recovered from the Australian outback) - and the mission was seen as a source of national pride in Japan, becoming the subject of movies and toys. Reporting on the unveiling this week, the Japan Times quotes mission leader Hitoshi Kuninaka as "grateful" that the new probe is finally complete, and hopeful that, this time, nothing goes wrong. “Of course, I hope things will go smoothly. We have had many difficulties in the process of developing the new asteroid probe. Space is never an easy place.”

Impactors like Hayabusa-2 are not new - Nasa's Deep Impact probe used a projectile in 2005 to stir up a cloud of debris it could then fly through and analyse - but the scale of the mission's ambition is uniquely large. It will briefly appear in the news again when it launches later this year, but the thing about probes like this - as we're seeing with Rosetta - is that they're investments which generate their own wonderful form of interest. Rosetta took ten years to reach its comet, making it almost as old as Hayabusa-1, but when it did remind of us of its lonely voyage it was with spectacular, gorgeous photographs. 2017 should hopefully bring us all another set of gifts.

The one where she turns into a USB stick: the worst uses of tech in films

The new film Worst Tinder Date Ever will join a long tradition of poorly-thought-through tech storylines.

News just in from Hollywood: someone is making a film about Tinder. What will they call it? Swipe Right, perhaps? I Super Like You? Some subtle allusion to the app’s small role in the plotline? Nope – according to Hollywood Reporterthe film has been christened Worst Tinder Date Ever.

With the exception of its heavily branded title (You’ve Got Gmail, anyone?), Worst Tinder Date Ever follows neatly in the tradition of writers manhandling tech into storylines. Because really, why does it matter if it was a Tinder date? This “rom com with action elements” reportedly focuses on the couple’s exploits after they meet on the app, so the dogged focus on it is presumably just a ploy to get millennial bums on cinema seats.  

Like the films on this list, it sounds like the tech in Worst Tinder Date Ever is just a byword for “modern and cool” – even as it demonstrates that the script is anything but.

Warning: spoilers ahead.

Lucy (2014)

Scarlett Johansson plays Lucy, a young woman who accidentally ingests large quantities of a new drug which promises to evolve your brain beyond normal human limits.

She evolves and evolves, gaining superhuman powers, until she hits peak human, and turns into first a supercomputer, and then a very long USB stick. USB-Lucy then texts Morgan Freeman's character on his fliphone to prove that: “I am everywhere.”

Beyond the obvious holes in this plotline (this wouldn’t happen if someone’s brain evolved; texting a phone is not a sign of omnipotence), USB sticks aren’t even that good – as Business Insider points out: “Flash drives are losing relevance because they can’t compete in speed and flexibility with cloud computing services . . . Flashdrives also can’t carry that much information.”

Star Wars: The Force Awakens (2015)

If you stare at it hard enough, the plotline in the latest Star Wars film boils down to the following: a gaggle of people travels across space in order to find a map showing Luke Skywalker’s location, held on a memory stick in a drawer in a spherical robot. Yep, those pesky flash drives again.

It later turns out that the map is incomplete, and the rest of it is in the hands of another robot, R2-D2, who won’t wake up for most of the film in order to spit out the missing fragment. Between them, creator George Lucas and writer and director JJ Abrams have dreamed up a dark vision of the future in which robots can talk and make decisions, but can’t email you a map.

Willy Wonka and the Chocolate Factory (1971)

In which a scientist uses a computer to find the “precise location of the three remaining golden tickets sent out into the world by Willy Wonka. When he asks it to spill the beans, it announces: “I won’t tell, that would be cheating.

The film inhabits a world where artificial intelligence has been achieved, but no one has thought to pull Charlie's poor grandparents out of extreme poverty, or design a computer with more than three buttons.

Independence Day (1996)

When an alien invasion threatens Earth, David Levinson (Jeff Goldblum) manages to stop it by hacking the alien spaceship and installing a virus. Using his Mac. Amazing, really, that aliens from across the universe would somehow use computing systems so similar to our own. 

Skyfall (2012)

In the Daniel Craig reboot of the series, MI6’s “Q” character (played by Ben Whishaw) becomes a computer expert, rather than just a gadget wizard. Unfortunately, this heralded some truly cringeworthy moments of “hacking” and “coding” in both Skyfall and Spectre (2014).

In the former, Bond and Q puzzle over a screen filled with a large, complex, web shape. They eventually realise it’s a map of subterranean London, but then the words security breach flash up, along with a skull. File under “films which make up their own operating systems because a command prompt box on a Windows desktop looks too boring”.

An honourable mention: Nelly and Kelly Rowland’s “Dilemma” (2009)

Not a movie, but how could we leave out a music video in which Kelly Rowland texts Nelly on a Microsoft Excel spreadsheet on a weird Nokia palm pilot?

You’ll be waiting a long time for that response, Kelly. Try Tinder instead.
