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.
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.

[Video Link] This Sunday night (and through the wee hours of Monday morning), engineers at NASA's Jet Propulsion Laboratory in Pasadena, CA will attempt to land the Mars Science Laboratory rover Curiosity on the surface of Mars. If the daring and complex landing plan goes right, Curiosity will enter the red planet's atmosphere, slow its descent by releasing a parachute, then lower itself to the surface on a tether with the help of a 'sky crane.' In this report for the PBS NewsHour, space journalist Miles O'Brien previews the highly anticipated space event. Read the full transcript here, and view video or download MP3 audio here.
Around that same time, I spoke with Ashwin Vasavada, Deputy Project Scientist at JPL for the MSL mission, to understand more about how MSL works and what its creators hope to accomplish, how one scores a job designing interplanetary explorer robots, and how this updated Mars rover is (or is not) like an iPad.

At the PBS NewsHour site, space journalist Miles O'Brien recounts the history of human exploration of the red planet, leading up to this Sunday's planned landing by the Mars Science Laboratory rover Curiosity. It's gonna be a nail-biter. Snip:
Ralph Harvey is a professor of planetary minerals at Case University. He spends a lot of time looking for Mars meteors in Antarctica. He has not yet seen anything that says "life" to him:
"When we argue about signs of possible life on Mars it's always the most subtle thing you can imagine," he told me a few years ago. "Something at the very edge of measurability, and life did not proceed that way on earth. Life is in your face. Life is something we have to scrape off the rocks to get to the story of the rocks. And I don't see that on Mars. I don't have that sense about Mars. So life on Mars is going to have to get in my face for me to believe it."
But what if life on Mars is hiding deep beneath the surface -- say in an underground aquifer? Could there be an underground habitable zone on Mars today?
NASA JPL's nuclear-powered Curiosity rover will try to land at the foot of a 3-mile-high mountain on Mars this Sunday night (technically, early Monday morning) to learn more about the possible building blocks of life there.
The rover is about the size of a car. The whole project costs about $2.5 billion. As you can see from JPL's now-viral "Seven Minutes of Terror" video, the landing process is something of a Rube Goldberg scheme. It'll be amazing if this works. It'll really suck for JPL, and the immediate future of space exploration funding, if it doesn't.
JPL's video demonstrating the engineering challenges in the precise timing of the descent of a human-crewed Mars lander is nail-biting territory. There's a reason they call the landing "seven minutes of terror."
Through the years, Ray Bradbury attended several major space mission events at JPL/Caltech. On Nov. 12, 1971, on the eve of Mariner 9 going into orbit at Mars, Bradbury took part in a symposium at Caltech with Arthur C. Clarke, journalist Walter Sullivan, and scientists Carl Sagan and Bruce Murray. In this excerpt, Bradbury reads his poem, "If Only We Had Taller Been."
The Eisriesenwelt—the "World of the Ice Giants"—is an Austrian cave that stays cold enough year-round to freeze any water that gets into it. As a result, the cave is full of massive ice formations. On April 28th, it was also full of people like physicist Daniel Schildhammer (seen above) who came to the cave to test out a wide array of space technologies, from protective suits to roving robots. It's all part of an international effort to prepare for a mission to Mars. Caves on Mars are likely place where bacteria and other forms of microbial life might be hiding out—the temperatures stay steady underground and the cave would protect those microbes from cosmic rays.

Yes, the deadline is tomorrow. But I know this is the perfect opportunity for at least one of you, so hop to it! Cornell and the University of Hawaii are putting together a series of studies aimed at finding out what it's going to take to keep people well-fed (both in the physical and psychological sense) during a trip to Mars. The research culminates in a 120-day analogue mission, during which subjects will live in a "Mars-like habitat", where they will eat nothing but rehydratable and instant space foods and will record data on factors like bodily odors and emotional well-being. If you've got a bachelor's degree in the sciences or engineering, a desire to contribute to the future of space travel, and a strong stomach, this might be the study for you! Here's the information on how to apply. (Via Paleofuture)
The Phobos-Grunt spacecraft may impact Earth in North America, South America, Europe, Asia or even Australia. “It’s not possible to say where the thing is going to fall down,” Heiner Klinkrad, head of the orbital debris office at the European Space Agency in Darmstadt, Germany, told The Washington Post in an interview today.
