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.

Clickbaiting terror: what it’s like to write viral news after a tragedy

Does the viral news cycle callously capitalise on terrorism, or is it allowing a different audience to access important news and facts?

On a normal day, Alex* will write anywhere between five to ten articles. As a content creator for a large viral news site, they [Alex is speaking under the condition of strict anonymity, meaning their gender will remain unidentified] will churn out multiple 500-word stories on adorable animals, optical illusions, and sex. “People always want to read about sexuality, numbers of sexual partners, porn habits and orgasms,” says Alex. “What is important is making the content easily-digestible and engaging.”

Alex is so proficient at knowing which articles will perform well that they frequently “seek stories that fit a certain template”. Though the word “clickbait” conjures up images of cute cat capers, Alex says political stories that “pander to prejudices” generate a large number of page views for the site. Many viral writers know how to tap into such stories so their takes are shared widely – which explains the remarkably similar headlines atop many internet articles. “This will restore your faith in humanity,” could be one; “This one weird trick will change your life…” another. The most cliché example of this is now so widely mocked that it has fallen out of favour:

You’ll never believe what happened next.

When the world stops because of a tragedy, viral newsrooms don’t. After a terrorist attack such as this week’s Manchester Arena bombing, internet media sites do away with their usual stories. One day, their homepages will be filled with traditional clickbait (“Mum Sickened After Discovery Inside Her Daughter’s Easter Egg”, “This Man’s Blackhead Removal Technique Is A Complete And Utter Gamechanger”) and the next, their clickbait has taken a remarkably more tragic tone (“New Footage Shows Moment Explosion Took Place Inside Manchester Arena”, “Nicki Minaj, Rihanna, Bruno Mars and More React to the Manchester Bombing”).

“When a terrorist event occurs, there’s an initial vacuum for viral news,” explains Alex. Instead of getting reporters on the scene or ringing press officers like a traditional newsroom, Alex says viral news is “conversation-driven” – meaning much of it regurgitates what is said on social media. This can lead to false stories spreading. On Tuesday, multiple viral outlets reported – based on Facebook posts and tweets – that over 50 accompanied children had been led to a nearby Holiday Inn. When BuzzFeed attempted to verify this, a spokesperson for the hotel chain denied the claim.

Yet BuzzFeed is the perfect proof that viral news and serious news can coexist under the same roof. Originally famed for its clickable content, the website is now home to a serious and prominent team of investigative journalists. Yet the site has different journalists on different beats, so that someone writes about politics and someone else about lifestyle or food.

Other organisations have a different approach. Sam* works at another large viral site (not Buzzfeed) where they are responsible for writing across topics; they explains how this works:  

“One minute you're doing something about a tweet a footballer did, the next it's the trailer for a new movie, and then bam, there's a general election being called and you have to jump on it,” they say.

Yet Sam is confident that they cover tragedy correctly. Though they feel viral news previously used to disingenuously “profiteer” off terrorism with loosely related image posts, they say their current outlet works hard to cover tragic news. “It’s not a race to generate traffic,” they say, “We won't post content that we think would generate traffic while people are grieving and in a state of shock, and we're not going to clickbait the headlines to try and manipulate it into that for obvious reasons.”

Sam goes as far as to say that their viral site in fact has higher editorial standards than “some of the big papers”. Those who might find themselves disturbed to see today’s explosions alongside yesterday’s cats will do well to remember that “traditional” journalists do not always have a great reputation for covering tragedy.

At 12pm on Tuesday, Daniel Hett tweeted that over 50 journalists had contacted him since he had posted on the site that his brother, Martyn, was missing after the Manchester attack. Hett claimed two journalists had found his personal mobile phone number, and he uploaded an image of a note a Telegraph reporter had posted through his letterbox. “This cunt found my house. I still don't know if my brother is alive,” read the accompanying caption. Tragically it turned out that Martyn was among the bomber's victims.

Long-established newspapers and magazines can clearly behave just as poorly as any newly formed media company. But although they might not always follow the rules, traditional newspapers do have them. Many writers for viral news sites have no formal ethical or journalistic training, with little guidance provided by their companies, which can cause problems when tragic news breaks.

It remains to be seen whether self-policing will be enough. Though false news has been spread, many of this week’s terror-focused viral news stories do shed light on missing people or raise awareness of how people can donate blood. Many viral news sites also have gigantic Facebook followings that far outstrip those of daily newspapers – meaning they can reach more people. In this way, Sam feels their work is important. Alex, however, is less optimistic.

“My personal view is that viral news does very little to inform people at times like this and that trending reporters probably end up feeling very small about their jobs,” says Alex. “You feel limited by the scope of your flippant style and by what the public is interested in.

“You can end up feeding the most divisive impulses of an angry public if you aren’t careful about what conversations you’re prompting. People switch onto the news around events like this and traffic rises, but ironically it’s probably when trending reporters go most into their shells and into well-worn story formats. It’s not really our time or place, and to try and make it so feels childish.”
