Mars rover

NASA’s expensive Mars exploration Curiosity rover is finally doing what it was created to do: rove. Following a successful wheel test, the probe moved forward. Photo Gallery: Curiosity Rover Makes First Tracks on Mars article tells that Curiosity beamed back some incredible images of its tracks, which tell scientists that the soil is firm, great for mobility, and won’t cause the rover to sink much. Curiosity also pulled out its big scientific guns, firing a laser beam at several rocks in the vicinity.

Yes, the Mars rover cost $2bn – but it’s far from a waste of money. Landing Curiosity on Mars was Way Harder and Way Less Expensive than the Olympics. Curiosity rover is about the size of a small SUV and weighs almost 900 kg. It uses scoops, cameras, drills, a powerful rock-vaporizing infrared laser, and 75 kilograms of scientific instruments to perform its investigation. Curiosity is very much based on commercial off-the-shelf (COTS) technology. Wind River’s VxWorks real-time operating system serves as the software platform for all functionality. Seeing the successful commencement of the Curiosity mission – powered by COTS – is certainly a cause for celebration amongst engineers.

    It’s only a product promo, but it’s a smart one: Nvidia reckons the judicious application of its graphics technology can debunk one of the world’s favourite “moon landing was a hoax conspiracies”.

    As a demo of the VXGI – voxel based global illumination – technology included in the company’s new Maxwell graphics architecture, a few enthusiasts at the company put together a rendered reconstruction of a scene that conspiracists say “prove” the landing was a hoax.

    the researchers were able to reproduce the conditions they say led to Aldrin being so apparently-anomalously well-illuminated in the photo.

    NASA’s Newest Mars Mission Spacecraft Enters Orbit around Red Planet
    http://www.nasa.gov/press/2014/september/nasa-s-newest-mars-mission-spacecraft-enters-orbit-around-red-planet/

    NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars’ orbit at 10:24 p.m. EDT Sunday, Sept. 21, where it now will prepare to study the Red Planet’s upper atmosphere as never done before. MAVEN is the first spacecraft dedicated to exploring the tenuous upper atmosphere of Mars.

    “As the first orbiter dedicated to studying Mars’ upper atmosphere, MAVEN will greatly improve our understanding of the history of the Martian atmosphere, how the climate has changed over time, and how that has influenced the evolution of the surface and the potential habitability of the planet,” said NASA Administrator Charles Bolden. “It also will better inform a future mission to send humans to the Red Planet in the 2030s.”

The achievement of its Asian rival has especially proven galling to the Chinese. China has yet to successfully send a space probe beyond the moon. The development has elicited calls in Beijing to accelerate China’s Mars program. China currently plans to send a rover to Mars in 2020 and, perhaps, do a Mars sample return mission in 2030.

    The comet is hurtling through space at 135,000km per hour towards the Sun, and the ESA hopes Philae will be able to separate from Rosetta, get close enough to harpoon the space rock and draw itself in to land, an effort that will take about seven hours to complete. Once on the rock, the lander will drill into the surface.

    Photonic Frontiers: Laser Space Instrumentation: Laser instruments earn their place in space for communications and lidar
    http://www.laserfocusworld.com/articles/print/volume-50/issue-11/features/photonic-frontiers-laser-space-instrumentation-laser-instruments-earn-their-place-in-space-for-communications-and-lidar.html?cmpid=EnlLFWNovember182014

    Solid-state lasers have earned their place in space instrumentation through programs that have mapped Mars, Mercury, and the Greenland ice sheet, and downlinked high-speed data from a lunar probe, but challenges remain.

    Lasers were born early in the space race, but the first successful space applications were based on the ground. Flashlamp-pumped solid-state lasers measured distance to the moon in 1962 and to satellites in 1964, but they had to be big and cumbersome to deliver the power needed for ranging. Gemini 7 astronauts tested a diode laser for communications in 1965, but clouds kept them from establishing a link to the ground receiver.

    By 1971, a lamp-pumped 0.05 Hertz Q-switched ruby laser altimeter on the Apollo 15 Lunar Orbiter was mapping part of the lunar surface.

    Lasers to Mars

    The first high-profile space mission to carry a diode-pumped laser was the ill-fated Mars Observer. Launched in September 1992 carrying the Mars Orbiter Laser Altimeter, it was lost on August 21, 1993, three days before it was to enter Mars orbit. Smaller laser altimeters later mapped the Moon and the near-earth asteroid Eros.

    On January 12, 2003, NASA launched the first satellite-borne lidar for continuous global observations of Earth, the Geoscience Laser Altimeter System, on ICESat-1, to study changes in the Greenland and Antarctic ice sheets. It carried three 1064 nm Nd-YAG lasers that were each supposed to operate continuously for 18 months, initially firing 70 mJ pulses.

    Laser communications

    Diode pumping also revived interest in high-speed laser links to deep space, where the limited speed of radio links had created a data bottleneck. After NASA’s plans to launch a 5 W, 100 Mbit/s laser relay called the Mars Telecommunications Orbiter in 2009 was cut in the 2005 budget, focus was shifted to a simpler test called the Lunar Laser Communication Demonstration (LLCD).5

    The LLCD transmitter was based on commercial telecommunication parts, including a distributed-feedback diode laser, erbium-fiber amplifiers, and a modulator, to avoid the high cost of lasers customized for space, says Donald Cornwell, director of NASA’s optical communications division (Washington, DC). Designed, built and operated by the MIT Lincoln Laboratory (Lexington, MA), the transmitter emitted 0.5 W at 1550 nm through a 10 cm telescope. A 16-ary pulse-position modulation encoded four data bits in pulse, to carry 622 Mbit/s from the Lunar Atmosphere and Dust Environment Explorer (LADEE) (see Fig. 2) in lunar orbit. To maximize sensitivity, the ground receiver used superconducting nanowire detector arrays operating at 1 to 3 K. A single 1550 nm photon can heat the 4 nm wire enough to stop superconductivity, says Cornwell. “It’s amazingly sensitive, with detection efficiency of 70 to 80%,” he adds.

    In October 2013, LLCD successfully demonstrated 622 Mbit/s downloads, six times the fastest radio link from the Moon, with a transmitter only half as massive.

    NASA’s next laser test will relay data at gigabit rates between a pair of ground stations. Both up- and down-laser links in the Laser Communications Relay Demonstration (LCRD) will be in the 1550-nm band, with a pair linking each ground station with a transceiver on a geosynchronous communications satellite. Initial plans called for a two-year test, but NASA is considering up to five years after a 2018 launch.

    NASA revisits Europa with modern image-processing software
    Do attempt landings here, says space agency, it looks VERY interesting
    http://www.theregister.co.uk/2014/11/24/nasa_revisits_europa_with_modern_imageprocessing_software/

    NASA has re-issued a famous image of Jovian moon Europa, after subjecting it to “modern image processing techniques” for the first time.

    The 1.6km-per-pixel, 2300×1700 image is actually a composite of several captured by the Galileo probe during the craft’s first and fourteenth orbits through the Jupiter system, in 1995 and 1998, respectively. Previous versions were “a mosaic with lower resolution and strongly enhanced color”.

    This time around, NASA has combined “Images taken through near-infrared, green and violet filters”, corrected them for “light scattered outside of the image, to provide a color correction that is calibrated by wavelength.”

    “ Gaps in the images have been filled with simulated color based on the color of nearby surface areas with similar terrain types.”

    As detailed by NASA scientists, New Horizons left our planet on January 19, 2006. It was launched from a space station in Florida, US, and is expected to begin studying Pluto sometime in January 2015.

    What this means is that the New Horizons spacecraft, whose overall weight is one of 478 kilograms (1,054 pounds), will soon become the first probe ever to study the Pluto system up close. Thus, in July 2015, the spacecraft is set to make its closest approach to the distant body.

    Two new papers on the latest data from the compact chemistry laboratory aboard nuclear-tank Curiosity show organic compounds in Mars’ atmosphere and rocks – and therefore offer tantalizing clues to the Red Planet’s watery past.

    In the past 20 months Curiosity’s Sample Analysis at Mars (SAM) laboratory has sniffed the air a dozen times using its mass spectrometer, gas chromatograph, and tunable laser spectrometer. As the rover has rolled across kilometres of Martian regolith the SAM instrument has sniffed four huge spikes in the methane content of the thin atmosphere – ten times the background reading – according to data published in Science.

    The blasts of organic material, which were detected by SAM in late 2013 and early 2014, aren’t necessarily proof of active organic life on Mars – it could be that they were formed by the action of water on Martian rocks’ chemical contents.

    Venus Express was launched in 2005 and took station around its namesake four months later to map out the planet’s weather systems.

    ALIEN fossils ON MARS: Curiosity snaps evidence of life
    ‘Worm’ trails in lake bed remarkably similar to Earth rock
    http://www.theregister.co.uk/2015/01/07/curiosity_fossils_mars/

    Photographs of rocks taken by NASA’s Curiosity rover may confirm that life as we know it once existed on Mars.

    The pictures were shot at the Gillespie Lake outcrop in Yellowknife Bay, which used to be a huge lake back when Mars had surface water. Dr Nora Noffke, who has spent 20 years studying fossils of early microbes, said formations in the Martian rocks looked very similar to those found on Earth – formations created by microorganisms.

    “In one image, I saw something that looked very familiar,” Noffke told Astrobiology Magazine. “So I took a closer look, meaning I spent several weeks investigating certain images centimetre by centimetre, drawing sketches, and comparing them to data from terrestrial structures.”

    Her research, published [PDF] in the journal Astrobiology, examined structures in the Martian rocks, and compared them to the remains of microbial organisms that were once the most advanced form of life on our planet. Interestingly enough, they match up.

    NASA Spacecraft Becomes First to Orbit a Dwarf Planet
    http://www.nasa.gov/press/2015/march/nasa-spacecraft-becomes-first-to-orbit-a-dwarf-planet/index.html#.VPtYwOEnJii

    NASA’s Dawn spacecraft has become the first mission to achieve orbit around a dwarf planet. The spacecraft was approximately 38,000 miles (61,000 kilometers) from Ceres when it was captured by the dwarf planet’s gravity at about 4:39 a.m. PST (7:39 a.m. EST) Friday.

    Mission controllers at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California received a signal from the spacecraft at 5:36 a.m. PST (8:36 a.m. EST) that Dawn was healthy and thrusting with its ion engine, the indicator Dawn had entered orbit as planned.

    “Since its discovery in 1801, Ceres was known as a planet, then an asteroid and later a dwarf planet,” said Marc Rayman, Dawn chief engineer and mission director at JPL. “Now, after a journey of 3.1 billion miles (4.9 billion kilometers) and 7.5 years, Dawn calls Ceres, home.”

    Curiosity rover’s broken arm heals, exploration-as-normal resumes
    Rover returns to showing Mars humanity’s mighty drilling skill
    http://www.theregister.co.uk/2015/03/16/curiosity_rovers_broken_arm_heals_explorationasnormal_resumes/

    The Curiosity rover’s arm is working again!

    In late February, NASA shut down the robotic limb after a short circuit led to errors. By March 7th, the space agency expressed optimism that the arm would come good.

    And last week, it did: NASA reports that last Wednesday the nuclear-powered laser-equipped space tank once again showed Mars that humanity means business by using its arm “to sieve and deliver a rock-powder sample to an onboard instrument.”

    LightSail mission stalled by .CSV log file embiggenment SNAFU
    Cubesat reboots after discovering that in space, no-one can press CTRL-ALT-DEL
    http://www.theregister.co.uk/2015/06/01/lightsail_avionics_wakes_up_after_nervous_silence/

    LightSail’s Jason Davis explains that the issue was down to a logfile in the avionics software that writes beacon events to a .csv file. In the version of Linux-based software running on the little spacecraft, a too-large beacon file crashes the system.

    “When it reaches 32 megabytes—roughly the size of ten compressed music files—it can crash the flight system. The manufacturer of the avionics board corrected this glitch in later software revisions. But alas, LightSail’s software version doesn’t include the update,” Davis writes.

    The spacecraft wasn’t responding to soft reboot commands from Earth, so there was nothing for it but to wait for the system to reboot itself, and that seems to have happened.

    Glass door to the ancient past FOUND ON MARS
    Red dust-stained geologists now working in vitro
    http://www.theregister.co.uk/2015/06/09/glass_door_to_the_ancient_past_found_mars/

    Rock-boffins have used data from satellites to scope out impact-crater glass on Mars for a glimpse into its past, based on the theory that glass formed during hypervelocity happenings can encapsulate and preserve earthly bio-signatures.

    A study lead by Brown University’s Peter Schultz found that organic matter, including plant matter, was entombed by molten glass formed in asteroid and comet impacts occurring millions of years ago in Argentina.

    When the study was published, the rock-boffin suggested that something similar could also have happened on Mars millions of years ago.

    The paper, Preserved glass-rich impactites on Mars, and published in Geology, is the first step in detecting the existence of impact glass on Mars.

    For those of us who were born into the “Star Trek” generation, we might use the opening voiceover by William Shatner as our mantra: “To explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before. The popularity of the newest Star Wars offerings, though, points to enthusiasm that crosses generation. Based on the latest winning projects on Kickstarter electronics free-thinkers are monetizing that enthusiasm with a variety of projects aimed at space exploration.

    By shelling out from $30 to $140 dollars, space enthusiasts, whether working in the electronics industry or standing on the sidelines, could feel like they were part of something greater than themselves. At the same time, it’s clear that the innovation continues to evolve as inventors look to capture space and space-themed projects and monetize them.

    Evidence of liquid water found on Mars
    http://www.bbc.com/news/science-environment-32287609

    Nasa’s Curiosity rover has found that water can exist as a liquid near the Martian surface.

    Mars should be too cold to support liquid water at the surface, but salts in the soil lower its freezing point – allowing briny films to form.

    The results lend credence to a theory that dark streaks seen on features such as crater walls could be formed by flowing water.

    The results are published in the journal Nature Geoscience.

    Scientists think thin films of water form when salts in the soil, called perchlorates, absorb water vapour from the atmosphere.

    The temperature of these liquid films is about -70C – too cold to support any of the microbial life forms that we know about.

    Forming in the top 15cm of the Martian soil, the brines would also be exposed to high levels of cosmic radiation – another challenge to life.

    The Rover Environmental Monitoring System (REMS) – essentially the vehicle’s weather station – measured the relative humidity and temperature at the rover’s landing site of Gale Crater.

    Scientists were also able to estimate the subsurface water content using data from an instrument called Dynamic Albedo of Neutrons (DAN). These data were consistent with water in the soil being bound to perchlorates.

    Finally, the Sample Analysis at Mars (SAM) instrument gave the researchers the content of water vapour in the atmosphere.

    The results show conditions were right for the brines to form during winter nights at the Martian equator, where Curiosity landed. But the liquid evaporates during the Martian day when temperatures rise.

    “These perchlorate salts have a property called deliquescence. They take the water vapour from the atmosphere and absorb it to produce the brines.”

    He added: “We see a daily water cycle – which is very important. This cycle is maintained by the brine. On Earth we have an exchange between the atmosphere and the ground through rain. But we don’t have this on Mars.”

    Dark streaks on slopes seen by orbiting spacecraft have long been thought to be the product of running water seeping from the Martian soil. But this interpretation has been contested.

    “It’s speculation at this point… but these observations at least support or go in this direction,” said Dr Martin-Torres.

    NASA Confirms Evidence That Liquid Water Flows on Today’s Mars
    https://www.nasa.gov/press-release/nasa-confirms-evidence-that-liquid-water-flows-on-today-s-mars

    New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars.

    Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time. They darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons. They appear in several locations on Mars when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius), and disappear at colder times.

    “Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington. “This is a significant development, as it appears to confirm that water — albeit briny — is flowing today on the surface of Mars.”

    These downhill flows, known as recurring slope lineae (RSL), often have been described as possibly related to liquid water. The new findings of hydrated salts on the slopes point to what that relationship may be to these dark features. The hydrated salts would lower the freezing point of a liquid brine, just as salt on roads here on Earth causes ice and snow to melt more rapidly. Scientists say it’s likely a shallow subsurface flow, with enough water wicking to the surface to explain the darkening.

    NASA Research Suggests Mars Once Had More Water Than Earth’s Arctic Ocean
    https://www.nasa.gov/press/2015/march/nasa-research-suggests-mars-once-had-more-water-than-earth-s-arctic-ocean

    A primitive ocean on Mars held more water than Earth’s Arctic Ocean, according to NASA scientists who, using ground-based observatories, measured water signatures in the Red Planet’s atmosphere

    “Our study provides a solid estimate of how much water Mars once had, by determining how much water was lost to space,” said Geronimo Villanueva, a scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the new paper. “With this work, we can better understand the history of water on Mars.”

    Perhaps about 4.3 billion years ago, Mars would have had enough water to cover its entire surface in a liquid layer about 450 feet (137 meters) deep. More likely, the water would have formed an ocean occupying almost half of Mars’ northern hemisphere, in some regions reaching depths greater than a mile (1.6 kilometers).

    NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s,” reads the official NASA web site. But National Geographic points out that “the details haven’t been announced, in large part because such a massive, long-term spending project would require the unlikely support of several successive U.S. presidents.”

    Journey to Mars Overview
    https://www.nasa.gov/content/journey-to-mars-overview

    NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s – goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010.

    Mars is a rich destination for scientific discovery and robotic and human exploration as we expand our presence into the solar system. Its formation and evolution are comparable to Earth, helping us learn more about our own planet’s history and future. Mars had conditions suitable for life in its past. Future exploration could uncover evidence of life, answering one of the fundamental mysteries of the cosmos: Does life exist beyond Earth?

    While robotic explorers have studied Mars for more than 40 years, NASA’s path for the human exploration of Mars begins in low-Earth orbit aboard the International Space Station. Astronauts on the orbiting laboratory are helping us prove many of the technologies and communications systems needed for human missions to deep space, including Mars. The space station also advances our understanding of how the body changes in space and how to protect astronaut health.

    Our next step is deep space, where NASA will send a robotic mission to capture and redirect an asteroid to orbit the moon. Astronauts aboard the Orion spacecraft will explore the asteroid in the 2020s, returning to Earth with samples. This experience in human spaceflight beyond low-Earth orbit will help NASA test new systems and capabilities, such as Solar Electric Propulsion, which we’ll need to send cargo as part of human missions to Mars.

    Luke Dubord, technical group supervisor, avionics subsystem engineering group, NASA, laid some truth on the opening keynote audience at this week’s Embedded Systems Conference in Boston.

    Dubord is a member of the team that safely landed NASA’s Curiosity rover on the fourth planet from the sun, early on August 6, 2012, eastern time. Since then, it has been communicating with NASA’s Mars Science Lab, passing valuable data and photos back to Earth.

    In discussing the NASA Curiosity Rover’s design, launch, successful landing, and continuing mission on Mars, Dubord touched on topics that, whether engineers want to accept or not, are real of all engineering, from simple consumer devices to complex spacecraft.
