ESA's elusive Mars lander Beagle2 discovered - but how?

Eureka! We've found Beagle2 – now, where did Philae go?

Landing a spacecraft on a celestial body, whether it be the moon, Mars or a comet, is not easy. The European Space Agency found out the hard way in 2003 when its robot Beagle2, which was supposed to send back a signal after landing on Mars, didn’t do so.

But more than a decade after it went missing, the UK Space Agency has announced that the Beagle2, the elusive lander, has been re-discovered.

Beagle2 was ejected from the Mars Express spacecraft on 19 December 2003, and was scheduled to land on 25 December. The landing had Beagle2 protected by inflated airbags, which would be released from the lander and roll away before deflating. Beagle2 would then deploy its solar panels, before communicating with orbiting craft. Unfortunately, no signal was received, and after desperate attempts to communicate with Beagle2, it was sadly concluded that the lander had been lost.

The subsequent inquiry found that the most likely causes of the loss were either a problem with the Entry, Descent and Landing System (EDLS) or sheer bad luck. It now looks as though the EDLS worked – so that leaves bad luck:

The images that have sparked the news come from the HiRise camera on board NASA’s Mars Reconnaissance Oriter. This is an instrument which is able to take very high resolution images of Mars’ surface. The scientists leading the search for the missing Beagle2 were looking for “something that wasn’t red, and wasn’t a pointy rock”. Given that this doesn’t narrow the field down very much, it is testament to the amazing perseverance and talents of the individuals concerned that they have managed to locate the lander.

It is poignant that the information comes at this time – Colin Pillinger was very much the driving force behind Beagle2, and one of the leaders of the Rosetta mission. His premature death last year deprived the scientific community of one of its most charismatic members. How he would have gloried in the re-discovery of Beagle2.

In contrast to the finding of Beagle2 comes news of another of ESA’s landers: Philae. Getting Rosetta spacecraft to drop Philae was an exciting and nerve-wracking time – the lander successfully sent an arrival signal, but subsequent information showed that Philae hadn’t landed where it was supposed to.

Since the mid-November landing, there have been several possible sightings of Philae from cameras on-board Rosetta. But none has been confirmed as the lander. Rosetta is continuing its science mission – which means that it has moved further away from the nucleus of comet 67P Churyumov-Gerasimenko. It is now taking wider-field images of the comet’s nucleus, to search for signs of developing surface activity, rather than the more narrow, specific area images that were being acquired in the search for Philae.

Even though the exact location of Philae is unknown, the lander is not lost. It is misplaced, and there is hope that when Rosetta next approaches close to the nucleus, in mid-February, it will once again be able to resume scanning for its delinquent child.

And what of ESA’s third lander – the hugely successful Huygens spacecraft? This is also celebrating its anniversary. It landed on Saturn’s moon, Titan, in January 2005. It did everything that was asked of it, landed where it was supposed to land, acquired the data it was supposed to acquire, and then, on time and with no fuss, quietly went to sleep. A lesson for other landers to learn?

The mother lode: how mums became the ultimate viral fodder

The internet’s favourite joke used to be "your mum". Now it's "my mum".

“I was like: oh my.”

Terri Squires is describing her reaction to the news that she had gone viral. Last month, more than 213,000 people shared a tweet about Terri – but it wasn’t sent from her account. The 50-year-old Ohioan was propelled to internet stardom by her son, Jeff, who had tweeted about his mother.

“I didn’t really realise what it meant at first until he was like: ‘Mum, you do realise that millions of people have looked at this?’ … When I started seeing those numbers I was like: ‘Oh boy’.”

It’s a funny story – and Terri laughs heartily all she tells it. After coming out of a meeting, she checked her phone and noticed a picture of a missing – white – dog on Facebook. She quickly texted 17-year-old Jeff to check that the family dog, Duey, was safe. “That’s not Duey… Duey’s face is brown,” replied her son. “OK – just checking,” replied Terri.

More than 600,000 people “liked” Terri’s mistake after Jeff shared screenshots of the text message exchange on Twitter. But Terri is just one of hundreds of mums who have gone viral via their sons and daughters. Texts mums send, mistakes they make, things they fail to notice – these have all become the ultimate viral fodder.

In the last three months alone, Gerald’s mum went viral for a microphone mishap, Adam’s mum shot to Twitter fame for failing to understand WhatsApp, Lois’ mum got tricked by her daughter, Harry’s mum was hit in the head with a football, Hanna’s mum misunderstood a hairstyle, and Jake’s mum failed to notice her son had swapped a photo in her home for a portrait of Kim Jong-un.

But how do the mothers behind these viral tweets feel?

“I'm pretty much a mum that everybody wants to talk to these days,” says Terri, with another warm laugh. The mum of three says going viral “is not that big of a deal” to her, but she is happy that her son can enjoy being a “local superstar”. But is she embarrassed at being the punchline of Jeff’s joke?

“Believe me, I have thick skin,” she says. “I kinda look at what it is, and it’s actually him and his fame. I’m just the mum behind it, the butt of the joke, but I don't mind.”

Not all mums feel the same. A handful of similar viral tweets have since been deleted, indicating the mothers featured in them weren’t best pleased. A few people I reach out to haven’t actually told their mums that they’re the subject of viral tweets, and other mums simply don’t want any more attention.

“I think I’ve put my mum through enough with that tweet already,” says Jacko, when I ask if his mum would be willing to be interviewed. In 2014, Jacko tweeted out a picture of his family writing the word “cock” in the air with sparklers. “This is still my favourite ever family photo,” he captioned the tweet, “My mum did the ‘O’. We told her we were going to write ‘Love’.”

“No one ever expects to call home and say ‘Mum, have you heard of something called LADbible? No, you shouldn’t have, it’s just that a quarter of a million of its fans have just liked a photo of you writing the word ‘cock’ with a sparkler’,” Jacko explains.

Although Jacko feels his mum’s been through enough with the tweet, he does say she was “ace” about her new found fame. “She’s probably cooler about it all than I am”. Apart from the odd deletion, then, it seems most mums are happy to become viral Twitter stars.

Yet why are mums so mocked and maligned in this way? Although dads are often the subject of viral tweets, this is usually because of jokes the dads themselves make (here’s the most notable example from this week). Mums, on the other hand, tend to be mocked for doing something “wrong” (though there are obviously a few examples of them going viral for their clever and cunning). On the whole: dads make jokes, mums are the butt of them.

“We all think our mums are so clueless, you know. They don’t know what’s going on. And the fun thing is, one day we come to realise that they knew way more of what was going on than we thought,” says Patricia Wood, a 56-year-old mum from Texas. “People always kind of make fun of their mums, but love them.”

Last year, Patricia went viral when her daughter Christina tweeted out screenshots of her mum’s Facebook posts. In them, Patricia had forgotten the names of Christina’s friends and had candidly written Facebook captions like: “My gorgeous daughter and her date for formal, sorry I forgot his name”. Christina captioned her tweet “I really can't with my mom” and went on to get more than 1,000 likes.

“I felt, like, wow, it was like we’re famous, you know. I thought it was really cool,” says Patricia, of going viral. Her experiences have been largely positive, and as a part-time Uber driver she enjoys telling her customers about the tweet. “But I did have one bad experience,” she explains. A drunken passenger in her car saw the tweet and called Patricia an “asshole”.

Another aspect of viral fame also worried Patricia. She and her daughter were invited on a reality show, TD Jakes, with the production company offering to pay for flights and hotels for the pair. “I have too many skeletons in my closet and I didn't want them to come dancing out,” says Patricia, of her decision not to go. “By the time I got off it, it would be the Jerry Springer show, you know. I’m kind of a strange bird.”

On the whole, then, mothers are often amused by going viral via their offspring – and perhaps this is the real beauty of tweeting about our mums. Since the moment they earn the title, mums can’t afford to be fragile. There is a joy and relatability in “my mum” tweets – because really, the mum in question could be anyone’s. Still, from now on, mums might be more careful about what they tell their sons and daughters.

“When I send Jeff a text now I make sure I’m like: ‘Is my spelling correct? Is what I’m saying grammatically correct?’,” says Terri, “Because who knows where the words are gonna end up?”
