  • HiRISE Principal Investigator Alfred McEwen said before the landing that they expected only a 60% chance of success
  • MRO was 340 km away from Curiosity when the image was taken, and that is line of sight distance, said Malkovich. “HiRISE has taken over 120 pictures of Gale Crater in preparation for MSL’s mission, but I think this is the coolest one,” she said.
  • more details and image products will be available and we will post them as soon as they are available

  • the HiRISE team already has plans to take images of Curiosity sitting on the surface of Mars later this week that will be of higher resolution than the descent image.

  • On May 28, 1971, the Soviet Union launched the Mars 3 mission which
  • consisted of an orbiter and lander destined for the Red Planet. Just over six months later on December 2, 1971, Mars 3 arrived at Mars
  • The Mars 3 descent module separated from the orbiter and several hours later entered the Martian atmosphere, descending to the surface via a series of parachutes and retrorockets
  • ...15 more annotations...
  • Once safely on the surface, the Mars 3 lander opened its four petal-shaped covers to release the 4.5-kg PROP-M rover contained inside… and after 20 seconds of transmission, fell silent
  • Due to unknown causes, the Mars 3 lander was never heard from or seen again
  • The set of images
  • shows what might be hardware from the 1971 Soviet Mars 3 lander, seen in a pair of images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.
  • Russian citizen enthusiasts found four features in a five-year-old image from Mars Reconnaissance Orbiter that resemble four pieces of hardware from the Mars 3 mission: the parachute, heat shield, terminal retrorocket and lander. A follow-up image by the orbiter from last month shows the same features
  • the largest Russian Internet community about Curiosity.
  • subscribers did the preliminary search for Mars 3 via crowdsourcing
  • modeled what Mars 3 hardware pieces should look like in a HiRISE image, and the group carefully searched the many small features in this large image, finding what appear to be viable candidates
  • Each candidate has a size and shape consistent with the expected hardware, and they are arranged on the surface as expected from the entry, descent and landing sequence
  • The predicted Mars 3 landing site was at latitude 45 degrees south, longitude 202 degrees east, in Ptolemaeus Crater
  • HiRISE acquired a large image at this location in November 2007, and promising candidates for the hardware from Mars 3 were found on Dec. 31, 2012
  • The candidate parachute is the most distinctive feature
  • an especially bright spot for this region, about 8.2 yards (7.5 meters) in diameter
  • The parachute would have a diameter of 12 yards (11 meters) if fully spread out over the surface
  • this set of features and their layout on the ground provide a remarkable match to what is expected from the Mars 3 landing, but alternative explanations for the features cannot be ruled out

  • ...25 more annotations...
  • The highly detailed image was freshly taken on Feb. 14 (Valentine’s Day 2014) by the telescopic High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter (MRO)
  • orbital image shows not only rover Opportunity at her location today, but
  • some of the wheel tracks created
  • as she climbed from the plains below up to near the peak of Solander Poin
  • The scene is narrowly focused on a spot barely one-quarter mile (400 meters) wide.
  • Endeavour is an impact scar created billions of years ago.
  • that infamous ‘jelly doughnut’ rock was actually the impetus for this new imaging campaign by NASA’s MRO Martian ‘Spysat.’
  • shiny 1.5 inches wide (4 centimeters)
  • , the science team decided to enlist the unparalleled capabilities of the HiRISE camera and imaging team in pursuit of answers.
  • To help solve the mystery
  • ‘Pinnacle Island’ had suddenly appeared out of nowhere in a set of before/after pictures taken by Opportunity’s cameras on Jan, 8, 2014 (Sol 3540)
  • exact same spot had been vacant of debris in photos taken barely 4 days earlier.
  • the HiRISE research team was called in to plan a new high resolution observation of the ‘Murray Ridge’ area and gather clues about the rocky riddle
  • The purpose was to “check the remote possibility that a fresh impact by an object from space might have
  • thrown this rock to its new location
  • no fresh crater impacting site was found in the new image
  • the mystery was solved at last by the rover team after Opportunity drove a short distance away from the ‘jelly doughnut’ rock
  • snapped some ‘look back’ photographs to document the ‘mysterious scene’ for further scrutiny.
  • Opportunity unknowingly ‘created’ the mystery herself when she drove over a larger rock, crushing and breaking it apart with the force from the wheels and her hefty 400 pound (185 kg) mass.
  • “Once we moved Opportunity a short distance, after inspecting Pinnacle Island, we could see directly uphill an overturned rock that has the same unusual appearance,”

  • The images were acquired by HiRISE between August 12, 2012 and January 13, 2013
  • The different images show distinct changes in the parachute, which is attached to the backshell that encompassed the rover during launch, flight and descent
  • This type of motion may kick off dust and keep parachutes on the surface bright, to help explain why the parachute from Viking 1 (landed in 1976) remains detectable
  • ...1 more annotation...
  • An animation of seven images from the HiRISE camera on the Mars Reconnaissance Orbiter show a “flapping” of the parachute that allowed the Curiosity rover to descend safely through Mars atmosphere images

  • fresh impact crater dominates this image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on Nov. 19, 2013.
  • Researchers used HiRISE to examine this site because the orbiter's Context Camera had revealed a change in appearance here between observations in July 2010 and May 2012
  • The crater spans approximately 100 feet (30 meters) in diameter and is surrounded by a large, rayed blast zone
  • ...3 more annotations...
  • In examining ejecta's distribution, scientists can learn more about the impact event
  • The explosion that excavated this crater threw ejecta as far as 9.3 miles (15 kilometers).
  • Before-and-after imaging that brackets appearance dates of fresh craters on Mars has indicated that impacts producing craters at least 12.8 feet (3.9 meters) in diameter occur at a rate exceeding 200 per year globally

  • Amazonis Planitia region of northern Mars
  • Evidence of many previous whirlwinds, or dust devils, are visible as streaks on the dusty surface shown in the image
  • like on Earth, winds on Mars are powered by solar heating
  • Mars is now farthest from the Sun,
  • though the exposure to the Sun’s rays is now less, even so, the dust devils are moving dust around on Mars’ surface
  • Dust devils occur on Earth as well as on Mars
  • spinning columns of air, made visible by the dust they pull off the ground
  • Unlike a tornado, a dust devil typically forms on a clear day
  • ground is heated by the sun, warming the air just above the ground
  • eated air near the surface rises quickly through a small pocket of cooler air above i
  • the air may begin to rotate, if conditions are just right.
