NASA JPL sends word today that image processing lab specialists have assembled a billion-pixel view from the surface of Mars, from NASA's Mars rover Curiosity. The 1.3-billion-pixel image is offered with pan and zoom tools here.

It's the first NASA-produced view from the surface of Mars at this resolution, and is stitched together from close to 900 exposures taken by cameras onboard Curiosity, revealing details of the landscape along the rover's route.

More from the JPL news release, below.

The full-circle scene surrounds the site where Curiosity collected its first scoops of dusty sand at a windblown patch called "Rocknest," and extends to Mount Sharp on the horizon.

"It gives a sense of place and really shows off the cameras' capabilities," said Bob Deen of the Multi-Mission Image Processing Laboratory at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "You can see the context and also zoom in to see very fine details."

Deen assembled the product using 850 frames from the telephoto camera of Curiosity's Mast Camera instrument, supplemented with 21 frames from the Mastcam's wider-angle camera and 25 black-and-white frames -- mostly of the rover itself -- from the Navigation Camera. The images were taken on several different Mars days between Oct. 5 and Nov. 16, 2012. Raw single-frame images received from Curiosity are promptly posted on a public website. Mars fans worldwide have used those images to assemble mosaic views, including at least one gigapixel scene.

The new mosaic from NASA shows illumination effects from variations in the time of day for pieces of the mosaic. It also shows variations in the clarity of the atmosphere due to variable dustiness during the month while the images were acquired.

NASA's Mars Science Laboratory project is using Curiosity and the rover's 10 science instruments to investigate the environmental history within Gale Crater, a location where the project has found that conditions were long ago favorable for microbial life.

Malin Space Science Systems, San Diego, built and operates Curiosity's Mastcam. JPL, a division of the California Institute of Technology in Pasadena, manages the project for NASA's Science Mission Directorate in Washington and built the Navigation Camera and the rover.

I'm sitting in on a NASA Jet propulsion laboratory teleconference for science journalists, with an update for the world on the Mars Curiosity rover's mission. Curiosity completes her "checkout" phase today. Including an "intermission" of 13 sols, and one remaining sol to inspect the rover's robotic arm, 26 sols have been devoted to so-called checkout duties. Today is sol 37. Rover is currently facing a Southeast direction. Temperatures on the rover are between 7 and 33 C. She has covered a little over a football field's distance on the surface of Mars. Ability to move the arm has been confirmed, and the ability of the rover to perform sampling is confirmed.

Curiosity has so far driven 109 meters from its original landing site, and engineers are driving her about 40 meters per sol. The first drilling into the surface of Mars is expected to occur about a month from now, following various surface activities (scraping rock surfaces, and so on).

Three speakers in the teleconference: Jennifer Trosper, JPL; Curiosity mission manager. Ralf Gellert, University of Guelph, in Guelph, Ontario, Canada; principal investigator for the Alpha Particle X-Ray Spectrometer instrument (or APXS) on Curiosity. Ken Edgett, Malin Space Science Systems, San Diego; principal investigator for the Mars Hand Lens Imager (or MAHLI) on Curiosity.

At the top of this blog post, the first Mars image of the day (larger size here):

Opening and Closing SAM. This set of images from NASA's Curiosity rover shows the inlet covers for the Sample Analysis at Mars instrument opening and closing, as the rover continues to check out its instruments in the first phase after landing. These images were taken by the Navigation camera on the 36th Martian day, or sol, of the rover's operations on Mars (Sept. 11, 2012). The rover's mast is casting a shadow over the deck. (NASA/JPL-Caltech)

Above, the Alpha Particle X-Ray Spectrometer (APXS) on NASA's Curiosity rover, with the Martian landscape in the background.

The image was taken by Curiosity's Mast Camera on the 32nd Martian day, or sol, of operations on the surface (Sept. 7, 2012, PDT or Sept. 8, 2012, UTC). APXS can be seen in the middle of the picture. This image let researchers know that the APXS instrument had not become caked with dust during Curiosity's dusty landing. Scientists enhanced the color in this version to show the Martian scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain.

JPL confirms that the APXS "Works great, good confirmation with the calibration target." And "There might be tweaking needed because of contamination," but scientists have all the tools they need working perfectly.

Tomorrow, a final set of checkouts, and special imaging events with cameras. Then, "drive, drive, drive," until the science team decides where to stop. Scientists packed a piece of Earth to take to Mars -- specifically, a chunk of New Mexico.

A sample of basaltic rock from a lava flow in New Mexico serves as a calibration target carried on the front of NASA's Mars rover Curiosity for the rover's Canadian-made Alpha Particle X-Ray Spectrometer (APXS) instrument. This image of the APXS calibration target was taken by the rover's Mars Hand Lens Imager (MAHLI) during the 34th Martian day, or sol, of Curiosity's work on Mars (Sept. 9, 2012). The image has been rotated to compensate for the tilted orientation of the camera when it was taken.

The prepared slab of well-characterized dark rock collected near Socorro, N.M., is held in a nickel mounting. The circular opening revealing the rock is about 1.4 inches (3.5 centimeters) in diameter. The Sol 34 imaging was part of characterization testing of the rover's arm and tools on the arm. A subsequent step commanded the arm-mounted APXS instrument to take a reading of the composition of the calibration target. Curiosity will use the target from time to time during the mission, checking the continuing performance and calibration of the APXS instrument.

APXS can identify chemical elements in rocks and soils. The spectrometer uses the radioactive element curium as a source to bombard the target with energetic alpha particles (helium nuclei) and X-rays. This causes each element in the target to emit its own characteristic X-rays, which are then registered by an X-ray detector chip inside the instrument's sensor head.

The rock in the calibration target is the hardest basalt of more than 200 types tested by the APXS team. Hardness was a desired attribute for preventing the target from breaking during the stresses of launch and landing. In addition, this basalt is low in sulfur, nickel and chlorine. Those elements are common in Martian dust. Thus, scientists using APXS will more easily detect and account for any Martian dust on the calibration target.

In the image below cropped from a larger scene by the Mars Hand Lens Imager (MAHLI), a penny with the first close-up images of Martian sand grains, seen right below Lincoln's ear (about 200 microns in size, or .2 mm) and one near the number 9 (about 100 microns, or .1 mm).

What science can we determine from this image? Edgett replies: The little sand grains on the penny are "just things that blew up on the penny during landing." They haven't been transported far, because if they were more round they'd have originated from a greater distance.

This is the first penny ever sent to Mars, and it was minted in the first year on which Lincoln's image was present on the coin.

One JPL scientist on the call, fumbling for a precise sol number as he describes an image, stops and says "Man, I am so tired." They've been on "Mars Time," following the daily solar cycles that Curiosity is on, and experiencing slow-motion sleep deprivation.

The most common type of rock on Mars is basalt, so that is what they're aiming for with the first gathering of samples in the days (and sols) to come.

And a little easter egg: The spaces in the tire treads in the image below are Morse Code for "J-P-L."

This view of the three left wheels of NASA's Mars rover Curiosity combines two images that were taken by the rover's Mars Hand Lens Imager (MAHLI) during the 34th Martian day, or sol, of Curiosity's work on Mars (Sept. 9, 2012). In the distance is the lower slope of Mount Sharp.

The camera is located in the turret of tools at the end of Curiosity's robotic arm. The Sol 34 imaging by MAHLI was part of a week-long set of activities for characterizing the movement of the arm in Mars conditions.

The main purpose of Curiosity's MAHLI camera is to acquire close-up, high-resolution views of rocks and soil at the rover's Gale Crater field site. The camera is capable of focusing on any target at distances of about 0.8 inch (2.1 centimeters) to infinity, providing versatility for other uses, such as views of the rover itself from different angles.

And above, a new image from Curiosity showing the open inlet where rock and soil samples will be funneled down for analysis. This photograph was captured by (MAHLI) on Curiosity's 36th Martian day, or sol, of operations on Mars (Sept. 11, 2012).

MAHLI was about 8 inches (20 centimeters) away from the mouth of the Chemistry and Mineralogy (CheMin) instrument when it took the picture. The entrance of the funnel is about 1.4 inches (3.5 centimeters) in diameter. The mesh screen is about 2.3 inches (5.9 centimeters) deep. The mesh size is 0.04 inches (1 millimeter). Once the samples have gone down the funnel, CheMin will be shooting X-rays at the samples to identify and quantify the minerals.

Engineers and scientists use images like these to check out Curiosity's instruments. This image is a composite of eight MAHLI pictures acquired at different focus positions and merged onboard the instrument before transmission to Earth; this is the first time the MAHLI performed this technique since arriving at Curiosity's field site inside Gale Crater. The image also shows angular and rounded pebbles and sand that were deposited on the rover deck during landing on Aug. 5, 2012 PDT (Aug. 6, 2012 EDT).

Like Burning Man, the ethos for rovers on Mars is "leave no trace." A journalist from Germany on the teleconference asks if the rover's activity will violate any internationally-agreed planetary protection agreements. A NASA headquarters spokesman says, "Curiosity is the cleanest rover NASA has ever sent to Mars. No prohibitions against planned drilling activity, based on what we expect the rover will do and where it will go."

As Curiosity was landing safely on Mars, many of you noted that the Jet Propulsion Laboratory engineers orchestrating the whole thing were eating an awful lot of peanuts. In fact, each workstation boasted a little commemorative jar of peanuts. Seriously, what is up with all those peanuts?

Discovery News has an answer. And it's surprisingly interesting.

Turns out, this is a JPL-specific tradition, dating back to 1964, when the lab's funding was on the line after the Ranger program—unmanned missions to photograph the Moon—weren't living up to expectations. In fact, six Ranger missions in a row had failed.

This was the heritage leading up to Ranger 7. There was talk that JPL should be shut down, that a university-affiliated center couldn’t handle a rigorous spaceflight program. There were suggestions that the program had been sabotaged -- a worker found a small polyethylene bag with 14 screws and a lock washer in one of the sealed electronic modules in Ranger 7’s television subsystem.

Just before Ranger 7 launched to the moon on July 28, mission manager Harris Schurmeier handed out peanuts to ease tensions. He figured chewing or playing with them on the table would give his team something else to focus on.

The full story is pretty neat. You can read the rest at Discovery News

As regular readers of this blog will recall, I asked a question of the Mars Curiosity team about imaging technologies during the post-landing press conference at NASA JPL a few days ago.

Related: Digital Photography Review now has an interview with the Mars rover camera project manager. Above, the 34mm (115mm equiv.) Mastcam from the Curiosity rover. This was developed by Mike Ravine and his team at Malin Space Science Systems, a contractor for NASA. Ravine explains how they developed the 2MP main imaging cameras used to transmit those breathtaking images back from Mars.

The slow data rates available for broadcasting images back to Earth and the team's familiarity with that family of sensors played a part, says [Ravine], but the biggest factor was the specifications being fixed as far back as 2004. Multi-shot panoramas will see the cameras deliver high-res images, he explains, but not the 3D movies Hollywood director James Cameron had wanted.

'There's a popular belief that projects like this are going to be very advanced but there are things that mitigate against that. These designs were proposed in 2004, and you don't get to propose one specification and then go off and develop something else. 2MP with 8GB of flash [memory] didn't sound too bad in 2004. But it doesn't compare well to what you get in an iPhone today.'

I had the honor and pleasure of meeting Maxwell at JPL a few weeks before Curiosity touched down, when I accompanied Miles O'Brien on a shoot about MSL for PBS NewsHour. Loved him, and I love how he describes what makes his job so exhilarating:

I don’t think I’ll ever forget the first time I drove her.  It was just a few meters along a simple path — we wouldn’t even bother to yawn at it today — but it was magic to me then, as it’s magic to me now.  I went home and should have slept, but all I could do was stare at the ceiling, in awe that right then, on Mars, there was a robot doing what I told it to do.  It was dead amazing, and that feeling has never left me and I hope it never will.

Engineers at NASA's Jet Propulsion Laboratory today received and published the first photograph shot by the Navigation cameras on NASA's Curiosity rover.

It shows the shadow of the rover's now-upright mast in the center, and the arm's shadow at left. The arm itself can be seen in the foreground. The navigation camera is used to help find the sun -- information that is needed for locating, and communicating, with Earth. After the camera pointed at the sun, it turned in the opposite direction and took this picture. The position of the shadow helps confirm the sun's location. The "augmented reality" or AR tag seen in the foreground can be used in the future with smart phones to obtain more information about the mission.

NASA's Jet Propulsion Laboratory was a magical place to be last night, as engineers, flight specialists, NASA administrators, space celebrities, and scientists from many fields gathered to witness the landing of the Mars Science Laboratory (MSL) Curiosity rover. Those seven minutes of terror ended in a picture-perfect landing: an amazing machine went through a crazy Rube Goldbergian descent sequence, and plopped down about two meters away from its planned destination on the Red Planet's surface.

We witnessed history. It seemed impossible. It was awesome.

I sat in on the post-landing press conference, and live-tweeted the evening at @boingboing. During the press conference, after the high-fives and screams of joy subsided, I asked MSL engineer Adam Steltzner a question about those first two all-important thumbnail images Curiosity sent back—critical because the data they contained would tell NASA if the rover had touched down in a safe spot.

[Video of that Q&A moment here.]

Given the great distance and technical challenges involved in transmitting timely data back from Mars, what file type and image compression algorithm(s) did they use for those first "rush" thumbnails? There's a 14 minute delay involved for any signals from Mars to Earth.

A dorky question, perhaps, but I was curious, and figured nobody else would ask. Things like, "Hey how do you guys feel right now," and "What will Curiosity do next," I knew others would tackle.

Mr. Steltzner didn't have details handy about the image file types used, and he referred me to Mars mission image specialist Justin Maki. Today I checked in with Mr. Maki and his JPL colleagues whose work focuses on data compression and interplanetary data transmission. Here's what I learned.

What space reporter Bill Harwood recounts on SpaceFlightNow is what I witnessed right there in the press room, too:

While engineers did not expect pictures right away, blurry low-resolution thumbnails from the rover's rear hazard avoidance cameras were transmitted within minutes of touchdown showing a wheel on the surface of Mars.

"Odyssey data is still strong," Chen reported. "Odyssey is nice and high in the sky. At this time we're standing by for images..."

"We've got thumbnails," someone said.

"We are wheels down on Mars!" Chen reported.

"Oh my God," someone said in the background.

They arrived faster than any of us in the audience expected, and they were of great significance in the moment. So how did they get to us? JPL imaging specialist Justin Maki, tells Boing Boing:

The images are wavelet-compressed, much like JPEG 2000. The main difference is that the algorithm used on MSL (and MER) use is computationally less complex than JPEG-2000.

Matt tells Boing Boing:

I don't have much to add beyond Justin's answer. It is a custom file format and the compression algorithm is in many ways similar to the algorithm for JPEG-2000 compression, but with lower computational complexity.

No name for the format (and I wouldn't necessarily characterize it as proprietary), but we call the compressor "ICER" (not an acronym, just a rearrangement of the letters of "Rice"; the Rice algorithm is a data compression algorithm first used decades ago).

And Boing Boing reader Darryl Lee points us to this JPL document (PDF) which contains specs for the lower-res cameras used on the MER rovers, Spirit and Opportunity.

"Curiosity has a much higher-resolution camera (MastCam), but the photographs sent last night were from the Hazcams, which are much lower-resolution," Darryl correctly notes.

Snip:

3.2. Image Compression

[48] To maximize the number of images acquired during the mission, virtually all image data will be compressed by the rover CPU (using either lossy or lossless compression) prior to placement into the telemetry stream. To perform this task the rovers will utilize a software implementation of the JPL-developed ICER wavelet-based image compressor [Kiely and Klimesh, 2003], capable of providing lossy and lossless compression. In cases where lossless compression is desired and speed is particularly important, compression will be performed (in software) by a modified version of the low-complexity (LOCO) lossless image compression algorithm [Klimesh et al., 2001; Weinberger et al., 1996]. The MER mission is utilizing state of the art image compression technology by flying compressors that deliver compression effectiveness comparable to that achieved by the JPEG- 2000 image compression standard [Adams, 2001], but with lower computational complexity [Kiely and Klimesh, 2003].

There's more details about ICER and LOCO in there, too.

And there you have it.

[Video Link] As the post-landing press conference begins, NASA and JPL MSL leaders high-five and cheer with the Mars rover engineering and flight control team. I shot this last night (on my iPhone, pardon the shakiness) inside the Jet Propulsion Lab, at 11:15pm PDT, about 45 minutes after the rover landed, against all odds, on the surface of Mars.

This just in from Mars:

NASA's Curiosity rover and its parachute were spotted by NASA's Mars Reconnaissance Orbiter as Curiosity descended to the surface on Aug. 5 PDT (Aug. 6 EDT). The High-Resolution Imaging Science Experiment (HiRISE) camera captured this image of Curiosity while the orbiter was listening to transmissions from the rover. Curiosity and its parachute are in the center of the white box; the inset image is a cutout of the rover stretched to avoid saturation. The rover is descending toward the etched plains just north of the sand dunes that fringe "Mt. Sharp." From the perspective of the orbiter, the parachute and Curiosity are flying at an angle relative to the surface, so the landing site does not appear directly below the rover.

The parachute appears fully inflated and performing perfectly. Details in the parachute, such as the band gap at the edges and the central hole, are clearly seen. The cords connecting the parachute to the back shell cannot be seen, although they were seen in the image of NASA's Phoenix lander descending, perhaps due to the difference in lighting angles. The bright spot on the back shell containing Curiosity might be a specular reflection off of a shiny area. Curiosity was released from the back shell sometime after this image was acquired.

They were chanting "Science! Science! Science!" and "NASA! NASA! NASA!" in Times Square last night, as the Curiosity rover touched down on Mars at about 1:30 am Eastern time.

The best parts are yet to come. As chemistry professor and blogger Matthew Hartings pointed out this morning, Curiosity is, fundamentally, a chemistry project. Curiosity will search for the chemical building blocks of life, it will study the make-up of the soil and atmosphere, it will look at planetary water cycles and the effects of cosmic radiation. The long-range goal, as you've probably picked up by now, is to put human beings on Mars—maybe by as soon as the 2030s. Curiosity is the chemistry that will help make that very ambitious sort of awesome possible.

We'll be staying tuned for cool stuff coming in from Curiosity. In the meantime, I wanted to point you toward some swell videos, photos, jokes, and essays that have turned up in the last nine hours.

First off, if you slept through the event or just want to relive the excitement, the video above captures the five minutes before and five minutes after Curiosity made landing. The actual touchdown happens about at about mark 5:30, and the first images come through at 7:30.

And, speaking of images ...

This teeny shot shows Curiosity and its trusty parachute landing on the Martian surface.

The Curiosity rover Twitter account posted this photo of the Martian surface (plus a wheel) last night.

Time magazine's Keith Wagstaff was in Times Square, reporting as the small, jaded, underwhelmed crowd slowly grew in both size and enthusiasm.

At 11:30pm EDT, when NASA started broadcasting coverage of the event, the crowd was thin and slightly underwhelmed. Many complained to me that the Toshiba Vision screen, dwarfed by a blinding Dunkin’ Donuts advertisement below it, was hard to see and that the only audio provided was through a smartphone app that seemed to be running a minute behind the visuals.

“NASA is a passing thing,” said Ben Brittain, an otherwise enthusiastic 19-year-old computer science student from the Rochester Institute for Technology. “I’m pretty sure this is going to be the last big thing NASA does.”

As the night, cool and wet thanks to a passing thunderstorm, went on, people began trickling in from every direction. ... Finally, 1:30am hit. Times Square was packed. People looked up intently with buds in their ears, listening to the back-and-forth chatter of scientists at NASA’s Jet Propulsion Laboratory near Los Angeles.

A cheer erupted. The rover’s first picture — a 256-pixel-by-256-pixel image of its own shadow against the Gale crater — was greeted with the hoots and applause normally reserved for winning touchdowns.

Philip Bump has a lovely essay over at Grist this morning, talking about the Olympics, Curiosity, human endeavor, and how very, very difficult it is to build something and have it work as perfectly as Curiosity did last night.

Jettisoning the carrier that moved it through open space, dropping its heat shield, then deploying a “sky crane” that would lay the car-sized rover on the surface of the planet before flying away. All of this had to happen in a seven minute window — without any contact with Earth.

It’s impossible to believe that it could work. That we could plan and build this nesting-doll piece of technology, launch it into space, land it in the spot we picked, and have it all still be working at the end. Fifty years ago, the idea of hitting Mars with anything, anywhere was pretty optimistic. One hundred years ago, leaving the atmosphere was an impossibility. But this was what we decided to do. Do the math, build it, throw it up there.

Meanwhile, on Earth, other bots were working less well as Scripps News Service managed to temporarily take down NASA's YouTube Curiosity footage via a spurious claim of copyright infringement. It's fixed now. But Motherboard's Alex Pasternack recorded the takedown notice for posterity.

YouTube’s system is also heavily biased in favor of claimants, and a system that is increasingly controlling of content that has serious educational or scientific value, or arguably falls under “fair use” provisions. Claims of fair use of video content are immaterial to the Content ID or DMCA takedown system. Creative remixes are easy targets, as are videos of teenagers singing Christmas songs. As I discovered last year, many of Martin Luther King, Jr.‘s speeches are no longer available on YouTube thanks to automatic and manual copyright claims by the owner of King’s speeches, the British music giant EMI Publishing. This despite the fact that YouTube is still a haven for illegal and uncontested uploads of millions of hours of Hollywood and music material.

And because anyone can claim a YouTube video belongs to them, YouTube’s system allows cheaters to direct traffic (and ad revenue) to their uploads. (Some preferred companies, like Universal Music Group, can even block videos immediately, without filing a claim.)

In less serious news, NASA's Mission Activity lead on the Curiosity landing, Bobak Ferdowsi, has literally become an overnight Internet celebrity thanks to his multi-colored mohawk. You can see fan art of Ferdowsi at The Atlantic, or buzz over to the Tumblr that has already been created in his honor.

Personally, I think Ferdowsi needs to tour America's schools, promoting the awesomeness of space alongside Space-X's rocket scientist/1970s vice cop Kevin Brogan.

And speaking of awesome scientists: Check out this profile of the guy who will be driving Curiosity around. CNN's Elizabeth Landau interviews Scott Maxwell, who also drove Spirit and Opportunity:

The baby, of course, is the SUV-sized Curiosity, coming to Mars after years of planning and preparation. It's been more than eight months since it left Earth, and no one can be sure exactly how it will behave, says Maxwell.

Over dinner in Old Pasadena this week, Maxwell and his girlfriend, Kim Lichtenberg—a planetary scientist also working on the rover mission—playfully compared it to having a child, though neither has had children.

"We're all going to be kind of like new parents," Lichtenberg says.

"Watch it take its first steps," Maxwell adds.

This is it, guys. Tonight's the night. NASA's Mars Science Laboratory rover Curiosity will attempt to land on the surface of Mars today. Here is Boing Boing's guide for how to follow her descent. Spaceflight Now's coverage should be excellent.

Here's an excellent history of human exploration of the red planet, by Miles O'Brien, and here's his report for PBS NewsHour chronicling Curiosity's long, strange trip.

Here's a photo gallery of Curiosity, during construction a year ago inside JPL. Here's my interview with JPL's Ashwin Vasavada, describing the science behind this amazing venture.

Science willing, I'll be at JPL tonight, and I'll send transmissions to the home blog. This is a wonderful and historic day for our exploration of the universe. I'm so happy to be alive to witness it.

Image above: An artist's still showing how NASA's Curiosity rover will communicate with Earth during landing. As the rover descends to the surface of Mars, it will send out two different types of data: basic radio-frequency tones that go directly to Earth (pink dashes) and more complex UHF radio data (blue circles) that require relaying by orbiters. NASA's Odyssey orbiter will pick up the UHF signal and relay it immediately back to Earth, while NASA's Mars Reconnaissance Orbiter will record the UHF data and play it back to Earth at a later time. (NASA/JPL-Caltech)

In April, 2011, the engineers at JPL gave Boing Boing permission to visit the clean room where the next Mars rover, Curiosity, had just been completed, for an exclusive first look.

Photographer Joseph Linaschke made the trek (and donned the bunny suit) on our behalf, and brought back breathtaking photos of the magnificent martian machine.

The full Boing Boing photo gallery is here, with caption assist from JPL.

Above, the Mars Science Laboratory's descent stage, which files the rover down to Mars' surface using eight rockets, and lowers it on a tether for landing. The orange spheres are propellant tanks.

Here's a roundup of ways to watch, as Curiosity attempts landing the night of Aug 5 (that's tomorrow).
