'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.
When nude photos of Jennifer Lawrence and other celebrities were stolen from Apple's iCloud and leaked online, the online privacy debate went viral.
The incident also highlighted how popular the practice is: 54 percent of U.S. adults participate in sexting, according to a recent study from security software firm McAfee. Sending racy texts, nude photos or explicit videos is most common among the 18-24 age group, with 70 percent saying they've received such a message.
With the risks so obvious, why do people do it?
Basic human instincts, experts said.
Our desire to connect is primal, but our daily lives are often physically disconnected, said Dara Greenwood, an associate professor of psychology at Vassar who studies mass media's impact on our perceptions of ourselves. Combined with the capabilities of today's technology, the selfie seemed inevitable (the naked selfie is an even more loaded phenomenon, she said).
"We derive a sense of self and identity from being seen, both literally and figuratively, and valued, so there is additional motivation to broadcast the self via photograph," Greenwood said. "In some ways the ubiquity of this photo-taking and sharing option may be overdetermining the behaviors that follow. In some basic sense, we take selfies because we can."
Life and love consultant Emily Straubel agrees, and says that sexting can be a positive method of expressing sexuality in relationships -- as long as a quick discussion of ground rules is established first.
"The things driving it are basic human nature," she said. "It's not an exclusive phenomenon of the Millennial generation. Base human traits are the motivation."
And in the context of a relationship, it feels safe, she said.
"I think a lot of people feel that there's so much trust in a relationship, they don't feel like it's necessarily taking a risk, just being flirtatious," she said.
When we see celebrities doing it, we're even more apt to snap those revealing shots -- again following a "fundamentally human phenomena that predated all this modern technology," Greenwood said. "Some of the trend is spread by social modeling and a desire to fit in with the group," she said.
Some personality types are more likely to engage in photo-based social media trends, Greenwood and Straubel said. People who are compelled by the idea of fame are more likely to follow and interact with celebrities online -- but they "may also end up feeding the very anxieties that motivated them to begin with (Am I important? Am I good enough?)" Greenwood said.
When people become too accustomed to looking at themselves from the outside in, she said, they may wind up putting too much emphasis on sex appeal -- making themselves overly vulnerable to the responses of others. (This may be especially true of adolescent sexting, which comes with its own unique dynamics, according to recent research.)
Indeed, there's a fine line between suggestive and exhibitionist, Straubel said.
"A selfie is one thing, a sexy photo is another, but a completely nude selfie is indicating something else," she said.
In the end, the technology may well enable social connection and self-worth, but in some cases it may also end up alienating us, unintentionally preventing us from more authentic communication and more multi-dimensional ways of being who we are, Greenwood said.
Because the act is so rooted in human nature, though, experts believe the trend will continue.
