Selfie Alert: Photos Often Don't Reflect the Real You
'Selfies' are all the rage these days. Every smartphone is attached with a camera and to the Internet, so it was inevitable that our vain species would take full advantage of the technology, snapping endless photos of cats and, of course, ourselves. Selfies -- or 'self portraits' to the uninitiated -- have become such a cultural phenomenon that Oxford University Press has declared 'Selfies' their word of the year. This may sound asinine, but Merriam-Webster Dictionary balanced it outand declared 'Science' their word of 2013
. In the spirit of fairness, I've combined the two words of the year and applied them to robots. Yes, robots. Robots that explore space, doing science. And just in case you didn't know, robots can be pretty vain too, taking snapshots of their junk for the whole Internet to see. To narrow the field down a bit, I've only selected robots that have photographed parts of their own structure, or attached components. I've also allowed the occasional robotic camera that was deployed for the sole purpose of taking a selfie
(nice effort, IKAROS).
The first robot that likely comes to mind is the undisputed
King of Selfies
, NASA's Mars Science Laboratory rover Curiosity. The car-sized rover impressed the world with its selfie prowess when mission scientists released a stunning high-resolution mosaic of the rover in November 2012, only a couple of months after it landed inside Gale Crater. Curiosity achieved the feat by holding its Mars Hand Lens Imager (MAHLI) at (robotic) arm's length, taking a truly authentic "selfie." The world applauded this effort.PHOTOS: Mars Through Curiosity's Powerful MAHLI Camera
But Curiosity certainly wasn't the first robot on Mars to snap its own picture, and it won't be the last. Although the Viking landers that touched down on the Red Planet in 1976 didn't have robotic arm-mounted cameras capable of taking a "true" selfie, they did their best.This view
from Viking 2 was snapped on Nov. 2, 1976, showing a part of the lander's deck, the American flag, the bottom of the robot's high-gain antenna and a boulder-littered Utopia Planitia, the largest identified impact crater on Mars.

Staying on Mars, some amazing panoramic shots and top-down self portraits have been attained by NASA's epic twin Mars Exploration Rovers Spirit and Opportunity. As you've probably guessed, commanding a robot on another planet to take self portraits isn't for fun (even though the outcome
a lot of fun), it actually serves a purpose. In the case of Viking and Curiosity, engineers on Earth can study the photos to see the condition of instruments on the robots' 'decks.'As shown here
, for solar powered rover Spirit, using its mast-mounted panoramic camera was very useful for capturing amazing 360 degree views of the surrounding terrain. It was also great for keeping track of the build-up of Martian dust on its panels. In this photo taken in 2005, Spirit's solar array shines in the sun, having collected only a very thin layer of dust two years after it landed.NEWS: 9 Years Later: Remembering Mars Rover Spirit
Spirit's twin rover Opportunity soldiers on to this day, exploring the Martian surface after nearly a decade since landing. Jan. 25, 2014, is its 10 year Mars "birthday" (mark your calendars!). Currently exploring the edge of Endeavour Crater, helping to piece together clues of Mars' evolution (complementing the science being done by Curiosity), Opportunity is no stranger to taking its own photo. As Spirit and Opportunity were designed to the same specifications, Opportunity can also take 360 degree views and monitor dust build-up on its solar panels.Seen here

No, robotic Mars explorers aren't especially fond of sefies, it's just that NASA has sent a lot of Mars surface missions in the past few years. Seen here in 2008, NASA's Mars arctic lander Phoenix took its own photo using a mast-mounted panoramic camera in a similar style to Spirit and Opportunity. It seems that the first rule of robotic selfies is: If it ain't broke, don't fix it.PHOTOS: Phoenix Mars Lander's First Images
Now for something a little different. In 2007, the European comet-chasing spacecraft Rosetta made close approach with Mars, coming within 1,000 miles of the surface, using the planet for a fuel-saving gravity assist. The boost in speed is allowing Rosetta to catch up with comet 67P/Churyumov–Gerasimenko -- an encounter that is planned for 2014. But during the flyby, the spacecraft managed to snap this iconic photo of Mars from space. What makesthis view
so special is that Rosetta also caught its own solar array in the shot.ANALYSIS: Advice to Rosetta: Maybe She's Just Not That Into You
Leaving Mars, we now head to Venus where, in 1982, the Soviet Venera 13 lander managed to survive the hellish conditions and transmit data for two hours. In that time it also returned some color photos of the Venusian surface. In those photos, the hardy lander was able to capture some of its jagged landing gear at the bottom of the shot. It may not be perfect, but while sitting in a pressure-cooker with a limited amount of time to return valuable data, it's a superb effort.ANALYSIS: When the Veneras Challenged Venus' Hellish Atmosphere

The Japanese Hayabusa asteroid sample return mission got a little creative with this selfie effort. In 2005, as it approached near-Earth asteroid Itokawa, with the sun at its back the mission snapped its shadow falling on the sunlit asteroid surface.

In 2010, the Japanese space agency JAXA launched a pioneering mission. Using only the sun's energy for propulsion, the Interplanetary Kite-craft Accelerated by Radiation Of the Sun, or IKAROS, probe set sail through interplanetary space for a January 2011 rendezvous with the planet Venus. After the solar sail was launched, two miniature wireless cameras were ejected by IKAROS as it deployed in Earth orbit,returning this admirable "hands free" self portrait
. Then, as IKAROS reached its destination eight months later, it took a snapshot of a crescent Venus (inset). (Thank youEmily Lakdawalla
for reminding me about these stunning IKAROS photos!)
Special thanks to all my Twitter buddies who engaged in Wednesday evening's conversation about robot selfies!
Can you think of more space mission "selfies"? Feel free to share them in the comments below.
Before you submit that headshot of yourself on LinkedIn or Facebook, you might want to consider — does it really show you in a good light?
A new study finds that people can glean wildly inaccurate first impressions of people based on slight variations in how a person's face is presented.
"The findings suggest that the images we post online can affect us in unexpected, and undesired, ways, subtly biasing other people's decisions," Alexander Todorov of Princeton University said in a press release.
Todorov and colleague Jenny Porter, of Columbia University, took an interest in how people interpret photos of others since so many people are perpetually adding to their online presence, whether on professional networking sites, dating sites, social networking sites or personal websites.
Other research has shown that people tend to form first impressions very quickly based on how a person looks. But when a person's face is presented in a static image, even small details can change that first impression dramatically.
"Our findings suggest that impressions from still photos of individuals could be deeply misleading," said Todorov.
For their study, the researchers presented subjects with headshots of different people. While the lighting and backgrounds of the photos remained the same, the images featured slight variations in facial expressions. The subjects were then asked to rate the images on various characteristics, including attractiveness, competence, creativity, cunning, extraversion, meanness, trustworthiness or intelligence.
The results showed that impressions of the same people presented in different photos varied as widely as impressions of photos of different people. In other words, how a person’s face was presented was everything.
"What we have shown here is something that people in the business of image manipulation have known for a long time," Todorov and Porter wrote.
So does this mean it might be wise to consult a professional when posting images of yourself on LinkIn, say, or a dating website? The authors argue, there's likely no way to present yourself in a full, true light when it comes to a photo. We are, after all, living, breathing humans whose expressions and body language and language change by the second.
"The face is not a still image frozen in time but rather a constantly shifting stream of expressions that convey different mental states," they note.
The key lesson, perhaps, is to never take too much stock in any person's single photo. Your best bet may be to just wait to meet them in person.
The research was published today in Psychological Science, a journal of the Association for Psychological Science.
