The solar arrays on NASA’s InSight lander are deployed in this test inside a clean room at Lockheed Martin Space Systems, Denver. This configuration is how the spacecraft will look on the surface of Mars.
'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 NASA’s InSight lander settles itself on the surface of Mars next year, a pair of tiny experimental satellites will be nearby to relay the action — in real time — back to Earth.
The project, spearheaded by NASA’s Jet Propulsion Laboratory in Pasadena, Calif., will mark the first time CubeSats travel in deep space.
CubeSats are standard 4- by 4- by 4-inch cubes that can be customized for a wide array of space missions. For the Mars Cube One project, engineers are building a pair of six-unit, radiation-hardened CubeSats, each outfitted with a softball-sized radio that can collect and transmit signals simultaneously. Only one satellite is needed for the mission, with the second flying as a spare.
Mars Cube One will supplement the communications relay from NASA’s Mars Reconnaissance Orbiter, which cannot simultaneously receive radio data from InSight in one frequency and transmit signals back to Earth on another.
Using Mars Cube One should speed up confirmation of a successful landing by more than an hour, NASA said.
The pair of CubeSats will piggyback rides on the Atlas 5 rocket that is scheduled to launch InSight in March. The lander, due to arrive in September 2016, is designed to collect data about the interior of Mars.
Mars Cube One will separate from the Atlas rocket and fly themselves to Mars, passing by just as InSight makes its descent through the planet’s atmosphere and touches down.
If the demonstration is successful, future Mars spacecraft could carry along their own communications relays, NASA said in a press release.
The U.S. space agency also is planning to launch an interplanetary nanosatellite pathfinder mission, called INSPIRE, in 2017 to test communications and other technologies needed for deep space missions.
NASA also is working on a pair of CubeSat science missions slated to fly in 2018. The Lunar Flashlight satellite will map the moon’s south pole for water and other volatiles; the Near Earth Asteroid Scout, which will use a solar sail to fly to an asteroid.
