First image of Mercury from orbit released

NASA released an image of the planet Mercury on Tuesday, the first obtained from a spacecraft orbiting the solar system's innermost planet.

The image is the first of many expected to come from the Messenger probe, the first space mission to orbit the planet closest to the sun. The Messenger spacecraft launched on August 3, 2004, and after flybys of Earth, Venus and Mercury, started its historic orbit around Mercury on March 17.

The dominant rayed crater in the upper portion of the image is Debussy, according to NASA. The smaller crater, Matabei, with its dark rays, is visible to the west of Debussy. The bottom portion of the full image, which can be seen here,  is near Mercury's south pole and includes a region of Mercury's surface not previously seen by spacecraft.

Over the next three days, Messenger will acquire 1,185 more images in support of a phase to review spacecraft and instrument performance. The yearlong primary science phase of the mission will begin on April 4, during which it is expected to acquire more than 75,000 images.

The Johns Hopkins University Applied Physics Laboratory built and operates the Messenger spacecraft and manages the Discovery-class mission for NASA. Messenger stands for MErcury Surface, Space ENvironment, GEochemistry, and Ranging.

    Typical ignorant CNN reporting. The Messenger spacecraft has been taking photos of Mercury for a couple of years now, hundreds. This is the first one from orbit but there are a lot more, even closer images that have been taken on flybys by Messenger in the last couple of years. This is not even as good a photo as a lot of those.

      ummm, the article states "and after flybys of Earth, Venus and MERCURY, started its historic orbit around Mercury on March 17."

      perhaps because fly-bys of Mercury have already been done in previous decades and the orbiting is the historic part, that's why they chose to focus on it??? maybe?

      Well, DUH, of course that's why they're focusing on this. But they should have made mention of the hundreds of awesome photos already taken by Messenger. They're acting like this was the first one. Get a brain dude.

      "Typical ignorant CNN reporting." Agreed in regards to CNN's space articles. (west of Debussy!!) However, if you read the article again, there is no claim of first or best.

    So has anyone explained why the impact craters are all nice circles instead of ellipses? Even here on Earth where we have a rich atmosphere we have plentiful examples of oblong-shaped impact craters. How can virtually all of the craters on Mercury be the result of near-perpendicular impacts (my assumption)? There must be a better explanation than vertical impact – perhaps a "sticky" surface?

      The existence of a Hermian atmosphere had been contentious before 1974, although by that time a consensus had formed that Mercury, like the Moon, lacked any substantial atmosphere. This conclusion was confirmed in 1974 when the Mariner 10 spacecraft discovered only a tenuous exosphere. Later, in 2008, improved measurements were obtained by the MESSENGER spacecraft, which discovered magnesium in the Hermian exosphere.

      We have no oblong shaped craters anywhere. Craters are almost alway circular no matter what the angle of the impacting body. It's a natural phenomena, I don't remember the details but it's basic physics, look it up.

    I believe alot of people reading this article should at least read up on more information regarding our solar system, or more if they wish. The only way we could inhabit another world in our solar system is taraforming, and that technology doesnt exist yet. On top of that it would need to be the same in every aspect to keep life as confortable as possible, as in orbital period, distance from the sun, size and atomosphere.

      Relax. Stephen Hawking believes that there exist an infinite number of parallel universes, and that that those with black holes constantly lose whatever information they generate. It is in these universe types that the vast majority of bloggers reside. You apparently reside in a universe that lacks black holes, and information is retained. Congratulations, a rare and valuable asset.

    There is absolutely nothing wrong with exploration...

    That said, there is absolutely something wrong with the American education system. I know, because I am American. How is it that money magically appears for projects of exploration, exploitation, and international emancipation?

    My old high school, paid millions of dollars for cosmetic updates to the building and surrounding area, but cut 3 vocational programs out of the curriculum. I went there to major in Aviation technology. I am 26 now and an underpaid, under appreciated, SECURITY GUARD! At a bank. FML.

    In 50 years there probably won't be a NASA for lack of educated persons to run the program. You state this science is important, I state that we need to focus on the structural integrity of this Nation before we go prancing around the globe and universe, otherwise the fruits of all this labor WILL be short lived...

      NASA takes up 0.07% of the national budget. Not even one percent of our national budget. Seriously it 0.07% & look at the research, technology & educational programs they provide with that money!!! I think the public needs to point the finger and vilify other programs for sucking up so much of our national budget for useless and wasteful things.
      And I'm not trying to pick a fight or be mean – but you only have yourself to blame if you're not happy with your job or education. EDUCATE YOURSELF. Read, study & learn on your own. Yes, our education system is awful – but educate yourself through any means available – which are endless! I had to do the same thing so I understand where you're coming from entirely. I finally began educating myself at libraries, online, etc. I truly hope things get better for you & you understand I'm not trying to be mean.

      I would like to see private industry take over space exploration anyway. NASA is just another bureaucracy. People like Burt Rutan are leading the way for the commercial exploitation of space. That will create jobs, tourism, technological advancement and a wealth of scientific knoledge without spening tax dollars. If there's a buck to be made in space, private industry will be all over it.

    Holy cow!!! Why are we still funding the space program when when there is a financial crisis never before seen in our history going on???!!! Why do we give a crap about Mercury? We will never be able to do anything there because it is so close to the sun. And even if we could, it would never happen.

    Of all the government agencies out there, NASA and the space programs are the biggest waste of money, time, people, and natural resources. Think about how much energy is wasted on a mission like this, including fuel to send the satelitte into space, the electrcal energy down here being used to monitor it and all the other equipment that is in use to gather the information. Not to meniton the fact that eventually this billion dollar probe will be floating around in space doing nothing.

    STOP BUDGETING FOR THE SPACE PROGRAM UNTIL OUR FINANCIAL SITUATION IS SOLVED!!!!!!

      You realize that this mission and the vehicle/spacecraft were funded years ago, probably during Clinton's Administration. And oh by the way, NASA is helping determine our place in the universe, and while the Shuttle program has essentially ended, there will be no mission to Mars...we still have spacecraft in orbit that are doing important scientific work. The Space telescopes, the various probes, etc. Stories like this about space and the solar system also serves to remind us that we are very small and insignificant in the universe. An asteroid could come hurtling out of near space and smash into the earth, creating a Human extinction event. And we might have thought of a way to prevent it, with NASA helping.

      John,

      You are absolutely right. I did a bit of research and it's amazing how much the government is wasting on this. A 1999 (http://nssdc.gsfc.nasa.gov/planetary/news/discovery_pr_19990707.html) put the cost of the mission at upwards of $300 million. That's 1999 dollars, btw. That cost in 2011 dollars (http://146.142.4.24/cgi-bin/cpicalc.pl) runs up to $400 million!! Another source (http://planetary.org/explore/topics/messenger/facts.html) I found places the cost even higher, at 427 million american dollars!! This is outrageous.

      It's time this government learns to focus on more important things, like defending our freedom. Take Iraq, for example. Based on what we're spending there (http://usgovinfo.about.com/library/weekly/aairaqwarcost.htm), the money NASA wasted on this mission could have funded our troops' war effort for 1.5 DAYS!!

      (Dear other readers, yes that was ironic, prove/disprove my numbers as you see fit)
