Curiosity "UFO" ID'ed?

The very first picture from Curiosity on the Martian surface turned the internet upside-down because of an object that looked like an odd formation of some sort. However, the image was just a thumbnail, or a smaller sized image of the original to give viewers a glimpse of the original image, and the resolution was not very good due to the thumbnail's small size. 

Because time was critical due to the pass of Mars Odyssey overhead relaying the telemetry and data before it went out of range of the rover, the smaller thumbnails were programmed to be relayed back to Earth, and only 2 thumbnail-sized images were transmitted before Mars Odyssey went beyond Curiosity's new Martian horizon.

Kaboom!
However, later in the day when more images were sent from the rover's Hazcam, the formation disappeared. Almost instantly the internet was abuzz with hypothetical ideas as to what the phenomenon was, from dust cover debris to UFO's.

The leading theory, however, may be even cooler than E.T.

It is suspected that the object was a dust cloud caused by the crash-landing of the rover's "sky-crane" stage moments after dropping Curiosity onto the ground, and intentionally flying away to prevent it from colliding with the rover. It is believed that, as Curiosity was getting used to its new home and was snapping pictures through its Hazcams, it caught the sky crane slamming into the ground some 2000 feet away!

Once the higher-resolution image was downloaded to Earth, the image resembled more of a mushroom cloud and the direction of the camera coincided with where the sky-crane crashed according to images sent back from the orbiting Mars Reconnaissance Orbiter.

Now the big question is, will Curiosity take a detour to the site to see what the dust cloud might have uncovered?

Incredible videos from Curiosity's descent

NASA
All eyes are on Mars this week as Curiosity made it's landing in one of the most complex maneuvers ever attempted on the red planet.

As curiosity descended it took video of its landing via the Mars Descent Imager, or MARDI. The video is grainy as the rover is currently sending thumbnail images (the high-res images will come in eventually, albeit slowly since they are so large and so many) to give a sample of what happened on it's way to the surface.

The concave black strips around the border are the result of the fish-eye lens that the camera was using to record the video. Fish-eye lenses allow a much larger field of view to be recorded. The view was inverted to flatten the background and present the video in a format more recognizable to viewers.


Along with the "good bye to the heat shield" video, MARDI also captured the landing. It's abbreviated, but NASA assures us a better video is on its way from the rover as soon as it can be sent.


Now that the high-gain antenna has been aligned with earth, we should be getting a lot more amazing pictures and videos in the upcoming days. I can't wait!

NASA gets interactive for Curiosity mission

The Mars Science Laboratory, AKA "Curiosity" is slated to land on Mars August 5. In preparation for the landing, NASA's come up with a slick interactive game for the Xbox 360 game console. 

Using the Kinect controller, you guide the Curiosity thru EDL (Entry, Descent, and Landing) as the rover makes its way to the Red Planet. I downloaded it tonight and ot to play a few rounds. The more accurate you are at each stage, the more points you are awarded. 

You first guide the vehicle through entry into the Martian atmosphere, and, using your body to keep the vehicle in the "center corridor". You'll go through pockets of turbulence and have to move the vehicle back to keep down the center line.


Next, you enter the descent phase, where you must time your movements to the pyrotechnics that deploy the parachute, eject the heat shield and finally remove the backshell, exposing the rover and leading to the final stage, landing.

In the landing stage you'll use your hands to guide the rover down to the target landing area. Accuracy and ease of landing (with the limited supply of fuel) will count as you put Curiosity down following its "7 minutes of terror".

The game also includes a video and some info on the overall mission. The opening screen contains a countdown timer to the actual landing of Curiosity on August 5th.

The game and video are narrated by Al Chen, who is the Flight Dynamics and Operations Lead for Curiosity. 

It's FREE to download (an Xbox Live membership is required, but you do not need to pay for use of the Live account) and available on the Xbox Live site.
