NASA announced the winners of the high stakes science instrument competition to fly aboard the Mars 2020 rover at a briefing held today, Thursday, July 31, at the agency’s headquarters in Washington, D.C.

The 2020 rover’s instruments goals are to search for signs of organic molecules and past life and help pave the way for future human explorers.

Seven carefully-selected payloads were chosen from a total of 58 proposals received in January 2014 from science teams worldwide, which is twice the usual number for instrument competitions and demonstrates the extraordinary interest in Mars by the science community.

The 2020 rover architecture is based on NASA’s hugely successful Mars Science Laboratory (MSL) Curiosity rover which safely touched down a one ton mass on Mars on Aug. 5, 2012 using the nail-biting and never before used skycrane rocket assisted descent system.

The seven instruments will conduct unprecedented science and technology investigations on the Red Planet that’s aimed for the first time at simultaneously advancing both NASA’s unmanned robotic exploration searching for extraterrestrial life and plans for human missions to Mars in the 2030’s.

Planning for NASA's 2020 Mars rover envisions a basic structure that capitalizes on the design and engineering work done for the NASA rover Curiosity, which landed on Mars in 2012, but with new science instruments selected through competition for accomplishing different science objectives.

The instruments will have the capability to detect low levels of organic molecules that are essential precursors to life.

A technology demonstration experiment will use Mars natural resources to generate oxygen from atmospheric carbon dioxide that can be used as rocket fuel or for human explorers. This will save enormous costs by enabling astronauts to ‘live off the land’ rather than having to bring everything needed for survival from Earth.

NASA said that the development cost for the chosen instruments is approximately $130 million out of a total cost of $1.9 Billion.

This overall cost is less than Curiosity’s approximate $2.4 Billion cost since the team is rebuilding the rover and landing architecture – sort of an MSL 2 so to speak – developed for Curiosity and also using several left over MSL flight spares.

The Mars 2020 rover will also have a sample cacher with the ability to store core samples collected by the rover’s drill for later retrieval and return to Earth at an as yet unspecified time.

“The Mars 2020 rover, with these new advanced scientific instruments, including those from our international partners, holds the promise to unlock more mysteries of Mars’ past as revealed in the geological record,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington.

“This mission will further our search for life in the universe and also offer opportunities to advance new capabilities in exploration technology.”

Here’s a list of the 7 selected science payload proposals. They are in some ways more advanced versions form Curiosity and in other ways completely new:

Mastcam-Z, an advanced camera system with panoramic and stereoscopic imaging capability with the ability to zoom. The instrument also will determine mineralogy of the Martian surface and assist with rover operations. The principal investigator is James Bell, Arizona State University in Phoenix.

SuperCam, an instrument that can provide imaging, chemical composition analysis, and mineralogy. The instrument will also be able to detect the presence of organic compounds in rocks and regolith from a distance. The principal investigator is Roger Wiens, Los Alamos National Laboratory, Los Alamos, New Mexico. This instrument also has a significant contribution from the Centre National d’Etudes Spatiales,Institut de Recherche en Astrophysique et Planetologie (CNES/IRAP) France.

Planetary Instrument for X-ray Lithochemistry (PIXL), an X-ray fluorescence spectrometer that will also contain an imager with high resolution to determine the fine scale elemental composition of Martian surface materials. PIXL will provide capabilities that permit more detailed detection and analysis of chemical elements than ever before. The principal investigator is Abigail Allwood, NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.

Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals (SHERLOC), a spectrometer that will provide fine-scale imaging and uses an ultraviolet (UV) laser to determine fine-scale mineralogy and detect organic compounds. SHERLOC will be the first UV Raman spectrometer to fly to the surface of Mars and will provide complementary measurements with other instruments in the payload. The principal investigator is Luther Beegle, JPL.

The Mars Oxygen ISRU Experiment (MOXIE), an exploration technology investigation that will produce oxygen from Martian atmospheric carbon dioxide. The principal investigator is Michael Hecht, Massachusetts Institute of Technology, Cambridge, Massachusetts.

Mars Environmental Dynamics Analyzer (MEDA), a set of sensors that will provide measurements of temperature, wind speed and direction, pressure, relative humidity and dust size and shape. The principal investigator is Jose Rodriguez-Manfredi, Centro de Astrobiologia, Instituto Nacional de Tecnica Aeroespacial, Spain.

The Radar Imager for Mars’ Subsurface Exploration (RIMFAX), a ground-penetrating radar that will provide centimeter-scale resolution of the geologic structure of the subsurface. The principal investigator is Svein-Erik Hamran, Forsvarets Forskning Institute, Norway.

So the instruments are more sophisticated, upgraded hardware versions as well as new instruments to conduct geological assessments of the rover’s landing site, determine the potential habitability of the environment, and directly search for signs of ancient Martian life, according to NASA.

Creating a Returnable Cache of Martian Samples is a major objective for NASA's Mars 2020 rover. This prototype show hardware to cache samples of cores drilled from Martian rocks for possible future return to Earth. The 2020 rover would be to collect and package a carefully selected set of up to 31 samples in a cache that could be returned to Earth by a later mission. The capabilities of laboratories on Earth for detailed examination of cores drilled from Martian rocks would far exceed the capabilities of any set of instruments that could feasibly be flown to Mars. The exact hardware design for the 2020 mission is yet to be determined. For scale, the diameter of the core sample shown in the image is 0.4 inch (1 centimeter).

“Today we take another important step on our journey to Mars,” said NASA Administrator Charles Bolden.

“While getting to and landing on Mars is hard, Curiosity was an iconic example of how our robotic scientific explorers are paving the way for humans to pioneer Mars and beyond. Mars exploration will be this generation’s legacy, and the Mars 2020 rover will be another critical step on humans’ journey to the Red Planet.”

Scientists Discover 101 Geysers Erupting at Saturn’s Intriguing Icy Moon Enceladus

This dramatic view looks across the region of Enceladus' geyser basin and down on the ends of the Baghdad and Damascus fractures that face Saturn. The image, which looks approximately in the direction of Saturn, was taken from a more elevated viewpoint than other Cassini survey images of this area of the moon's south pole. Credit: NASA/JPL-Caltech/SSI

Scientists analyzing the reams of data from NASA’s Cassini orbiter at Saturn have discovered 101 geysers erupting from the intriguing icy moon Enceladus and that the spewing material of liquid water likely originates from an underground sea located beneath the tiny moons ice shell, according to newly published research.

The geysers are composed of tiny icy particles, water vapor and trace amounts of simple organic molecules. They were first sighted in Cassini imagery snapped during flyby’s of the 310-mile-wide (500 kilometers wide) moon back in 2005 and immediately thrust Enceladus forward as a potential abode for alien life beyond Earth and prime scientific inquisition.

Liquid water, organic molecules and an energy source are the key requirements for life as we know it.

The eruptions emanated from a previously unknown network of four prominent “tiger stripe” fractures, named Damascus, Baghdad, Cairo and Alexandria sulci, located at the south polar region of Saturn’s sixth largest moon.

Using imagery gathered over nearly seven years of surveys by Cassini’s cameras, researchers generated a survey map of the 101 geysers erupting from the four tiger strips.

This artist's rendering shows a cross-section of the ice shell immediately beneath one of Enceladus' geyser-active fractures, illustrating the physical and thermal structure and the processes ongoing below and at the surface.

The new findings and theories on the physical nature of how the geysers erupt have been published in two articles in the current online edition of the Astronomical Journal.

Scientists had initially postulated that the origin of the geysers could be frictional heating generated from back and forth rubbing of the opposing walls of the tiger stripe fractures that converted water ice into liquids and vapors. Another theory held that the opening and closing of the fractures allowed water vapor from below to reach the surface.

The geysers locations was eventually determined to coincide with small local hot spots erupting from one of the tiger stripe fractures after researchers compared low resolution thermal emission maps with the geysers’ locations and found the greatest activity at the warmest spots.

After later high-resolution data was collected in 2010 by Cassini’s heat-sensing instruments the geysers were found to coincide with small-scale hot spots, measuring only a few dozen feet (or tens of meters) across.

“Once we had these results in hand we knew right away heat was not causing the geysers, but vice versa,” said Carolyn Porco, leader of the Cassini imaging team from the Space Science Institute in Boulder, Colorado, and lead author of the first paper. “It also told us the geysers are not a near-surface phenomenon, but have much deeper roots.”

This graphic shows a 3-D model of 98 geysers whose source locations and tilts were found in a Cassini imaging survey of Enceladus' south polar terrain by the method of triangulation. While some jets are strongly tilted, it is clear the jets on average lie in four distinct "planes" that are normal to the surface at their source location.

“Thanks to recent analysis of Cassini gravity data, the researchers concluded the only plausible source of the material forming the geysers is the sea now known to exist beneath the ice shell. They also found that narrow pathways through the ice shell can remain open from the sea all the way to the surface, if filled with liquid water,” according to a NASA press release.

These are very exciting results in the search for life beyond Earth and clearly warrant a follow up mission.

“In casting your sights on the geysering glory of Enceladus, you are looking at frozen mist that originates deep within the solar system’s most accessible habitable zone,” writes Porco in her Captain’s Log summary of the new findings.

The Cassini-Huygens mission is a cooperative project between NASA, the European Space Agency (ESA) and the Italian Space Agency (ASI). Cassini was launched by a Titan IV rocket in 1997 and arrived at Saturn in 2004.

In 2005 Cassini deployed the Huygens probe which landed on Titan, Saturn’s largest moon sporting oceans of organic molecules and another prime location in the search for life.

The Cassini mission will conclude in 2017 with an intentional suicide dive into Saturn to prevent contamination on Titan and Enceladus – but lots more breathtaking science will be accomplished in the meantime!

Sparks Fly on Mars as Curiosity Laser Blasts Red Planet Rock – Photos/Video

Curiosity has zapped hundreds of Red Planet rocks with her powerful laser blaster during her lifetime and has now caught the sparks flying for the first time as they happened – as seen in new photos and video above and below released this week by NASA.

As the NASA rover’s million watt Chemistry and Camera (ChemCam) instrument fired multiple laser shots at a rock fortuitously named “Nova” the team commanded her arm-mounted Mars Hand Lens Imager (MAHLI) high resolution imaging camera to try and capture the action as it occurred, for the first time. And they succeeded.

Curiosity blasted the baseball sized “Nova” rock target over 100 times on July 12, 2014, or Sol 687.

Since the nail biting touchdown nearly two years ago on Aug. 5, 2012 inside Gale Crater, ChemCam has aimed the laser instrument at more than 600 rock or soil targets and fired more than 150,000 laser shots.

Here’s a NASA/JPL video showing the laser flash:

Video Caption: The sparks that appear on the baseball-sized rock (starting at :17) result from the laser of the ChemCam instrument on NASA’s Curiosity Mars rover hitting the rock. Credit: NASA/JPL-Caltech/MSSS

ChemCam is used to determine the composition of Martian rocks and soils at a distance of up to 25 feet (8 meters) yielding preliminary data for the scientists and engineers to decide if a target warrants up close investigation and in rare cases sampling and drilling activities.

ChemCam works through a process called laser-induced breakdown spectroscopy. The laser hits a target with pulses to generate sparks, whose spectra provide information about which chemical elements are in the target.

Successive laser shots are fired in sequence to gradually blast away thin layers of material. Each shot exposes a slightly deeper layer for examination by the ChemCam spectrometer.

As Curiosity fired deeper into “Nova” it showed an increasing concentration of aluminum as the sequential laser blasts penetrated through the uninteresting dust on the rock’s surface. Silicon and sodium were also detected.

“This is so exciting! The ChemCam laser has fired more than 150,000 times on Mars, but this is the first time we see the plasma plume that is created,” said ChemCam Deputy Principal Investigator Sylvestre Maurice, at the Research Institute in Astrophysics and Planetology, of France’s National Center for Scientific Research and the University of Toulouse, France, in a statement.

“Each time the laser hits a target, the plasma light is caught and analyzed by ChemCam’s spectrometers. What the new images add is confirmation that the size and shape of the spark are what we anticipated under Martian conditions.”

A Martian target rock called "Nova," shown here, displayed an increasing concentration of aluminum as a series of laser shots from NASA's Curiosity Mars rover penetrated through dust on the rock's surface. This pattern is typical of many rocks examined with the rover's laser-firing ChemCam.

The SUZ sized rover is driving as swiftly as possible to the base of Mount Sharp which dominates the center of Gale Crater and reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Rainier.

During Year 1 on Mars, Earth’s emissary has already accomplished her primary objective of discovering a habitable zone on the Red Planet that contains the minerals necessary to support microbial life in the ancient past when Mars was far wetter and warmer billions of years ago.

To date, Curiosity’s odometer totals over 5.1 miles (8.4 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 166,000 images.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the treacherous sand dunes at the foothills of Mount Sharp sometime later this year.

NASA’s Carbon Observatory Blasts off on Workhorse Delta II to Measure Carbon Dioxide Greenhouse Gas and Watch Earth Breathe

Story updated[/caption]

Following a nearly three-year long hiatus, the workhorse Delta II rocket successfully launched NASA’s first spacecraft dedicated to watching Earth breathe by studying Earth’s atmospheric carbon dioxide (CO2) – the leading human-produced greenhouse gas and the principal human-produced driver of climate change.

The Orbiting Carbon Observatory-2 (OCO-2) raced to orbit earlier this morning, during a spectacular nighttime blastoff at 2:56 a.m. PDT (5:56 a.m. EDT), Tuesday, July 2, 2014, from Vandenberg Air Force Base, California, atop a United Launch Alliance Delta II rocket.

The flawless launch marked the ‘return to flight’ of the venerable Delta II and was broadcast live on NASA TV.

A camera mounted on the Delta II’s second stage captured a breathtaking live view of the OCO-2 spacecraft during separation from the upper stage, which propelled it into an initial 429-mile (690-kilometer) orbit.

The life giving solar arrays were unfurled soon thereafter and NASA reports that the observatory is in excellent health.

“Climate change is the challenge of our generation,” said NASA Administrator Charles Bolden in a statement.

“With OCO-2 and our existing fleet of satellites, NASA is uniquely qualified to take on the challenge of documenting and understanding these changes, predicting the ramifications, and sharing information about these changes for the benefit of society.”

Over the next three weeks the OCO-2 probe will undergo a thorough checkout and calibration process. It will also be maneuvered into a 438-mile (705-kilometer) altitude, near-polar orbit where it will become the lead science probe at the head of the international Afternoon Constellation, or “A-Train,” of Earth-observing satellites.

“The A-Train, the first multi-satellite, formation flying “super observatory” to record the health of Earth’s atmosphere and surface environment, collects an unprecedented quantity of nearly simultaneous climate and weather measurements,” says NASA.

Science operations begin in about 45 days.

The 999 pound (454 kilogram) observatory is the size of a phone booth.

OCO-2 is equipped with a single science instrument consisting of three high-resolution, near-infrared spec¬trometers fed by a common telescope. It will collect global measurements of atmospheric CO2 to provide scientists with a better idea of how CO2 impacts climate change and is responsible for Earth’s warming.

During a minimum two-year mission the $467.7 million OCO-2 will take near global measurements to locate the sources and storage places, or ‘sinks’, for atmospheric carbon dioxide, which is a critical component of the planet’s carbon cycle.

OCO-2 was built by Orbital Sciences as a replacement for the original OCO which was destroyed during the failed launch of a Taurus XL rocket from Vandenberg back in February 2009 when the payload fairing failed to open properly and the spacecraft plunged into the ocean.

The OCO-2 mission will provide a global picture of the human and natural sources of carbon dioxide, as well as their “sinks,” the natural ocean and land processes by which carbon dioxide is pulled out of Earth’s atmosphere and stored, according to NASA.

“This challenging mission is both timely and important,” said Michael Freilich, director of the Earth Science Division of NASA’s Science Mission Directorate in Washington.

“OCO-2 will produce exquisitely precise measurements of atmospheric carbon dioxide concentrations near Earth’s surface, laying the foundation for informed policy decisions on how to adapt to and reduce future climate change.”

It will record around 100,000 precise individual CO2 measurements around the worlds entire sunlit hemisphere every day and help determine its source and fate in an effort to understand how human activities impact climate change and how we can mitigate its effects.

At the dawn of the Industrial Revolution, there were about 280 parts per million (ppm) of carbon dioxide in Earth’s atmosphere. As of today the CO2 level has risen to about 400 parts per million.

“Scientists currently don’t know exactly where and how Earth’s oceans and plants have absorbed more than half the carbon dioxide that human activities have emitted into our atmosphere since the beginning of the industrial era,” said David Crisp, OCO-2 science team leader at NASA’s Jet Propulsion Laboratory in Pasadena, California, in a statement.

“Because of this, we cannot predict precisely how these processes will operate in the future as climate changes. For society to better manage carbon dioxide levels in our atmosphere, we need to be able to measure the natural source and sink processes.”

OCO-2 is the second of NASA’s five new Earth science missions planned to launch in 2014 and is designed to operate for at least two years during its primary mission. It follows the successful blastoff of the joint NASA/JAXA Global Precipitation Measurement (GPM) Core Observatory satellite on Feb 27.

The two stage Delta II 7320-10 launch vehicle is 8 ft in diameter and approximately 128 ft tall and was equipped with a trio of first stage strap on solid rocket motors. This marked the 152nd Delta II launch overall and the 51st for NASA since 1989.

The last time a Delta II rocket flew was nearly three years ago in October 2011 from Vandenberg for the Suomi National Polar-Orbiting Partnership (NPP) weather satellite.

The final Delta II launch from Cape Canaveral on Sept. 10, 2011 boosted NASA’s twin GRAIL gravity mapping probes to the Moon.

The next Delta II launch later this year from Vandenberg involves NASA’s Soil Moisture Active Passive (SMAP) mission and counts as another of NASA’s five Earth science missions launching in 2014.

Trekking Mars – Curiosity Roves Outside Landing Ellipse!

Trekking Mars – NASA’s intrepid robot Curiosity is roving rapidly across the sandy ripples of the Red Planet in her quest to reach mysterious Mount Sharp and just drove outside her landing ellipse!

The six wheeled rover marked a major milestone on Sol 672, June 27, 2014, by traversing beyond her targeted landing ellipse for the first time since touchdown on Mars nearly two years ago on August 5, 2012.

“On yestersol’s drive [June 27], I left my landing ellipse—the 20×25 km area I targeted for landing,” Curiosity tweeted across interplanetary space.

See our new Sol 672 photo mosaic above showing Curiosity’s glorious view marking this major achievement just days ago.

Since switching paths to smoother, sandier terrain with less sharp edged rocks, Curiosity continues rolling across the floor of her Gale Crater landing site, pausing occasionally for potentially dicey dunes.

“After traversing 82 meters the rover stopped because it determined that it was slipping too much,” wrote mission scientist Ken Herkenhoff in an update.

“Coincidentally, the rover stopped right on the landing ellipse, a major mission milestone!”

1 Martian Year on Mars!

“The vehicle was designed to be able to traverse far enough to drive out of the region defined by the uncertainty in the landing location, and has now achieved that laudable goal,” Herkenhoff confirmed.

The SUV sized rover automatically stopped when it encountered soft sand and sensed that it wasn’t making enough progress. It’s been programmed with this built in safety check to avoid being trapped in a quagmire of quicksand.

Earlier last week, Curiosity celebrated another milestone anniversary on June 24 (Sol 669) – 1 Martian Year on Mars!

A Martian year is equivalent to 687 Earth days, or nearly two Earth years.

See our Sol 669 photo mosaic marking 1 Mars Year on Mars – above.

So there’s no stopping Curiosity on her way to Mount Sharp, which dominates the center of Gale Crater and reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Rainier.

Driving, Driving, Driving – that’s Curiosity’s number one priority as she traverses across the surface of Gale Crater towards towering Mount Sharp on an expedition in search of the chemical ingredients of life that could support Martian microbes if they ever existed.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the dunes at the foothills of Mount Sharp sometime later this year.

After a lengthy hiatus, the workhorse Delta II rocket that first launched a quarter of a century ago and placed numerous renowned NASA science missions into Earth orbit and interplanetary space, as well as lofting dozens of commercial and DOD missions, is about to soar again this week on July 1 with NASA’s Orbiting Carbon Observatory-2 (OCO-2) sniffer to study atmospheric carbon dioxide (CO2).

OCO-2 is NASA’s first mission dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas and the principal human-produced driver of climate change.

The 999 pound (454 kilogram) observatory is equipped with one science instrument consisting of three high-resolution, near-infrared spectrometers fed by a common telescope. It will collect global measurements of atmospheric CO2 to provide scientists with a better idea of how CO2 impacts climate change.

The $467.7 million OCO-2 mission is set to blastoff atop the United Launch Alliance (ULA) Delta II rocket on Tuesday, July 1 from Space Launch Complex 2 at Vandenberg Air Force Base in California.

Liftoff is slated for 5:56 a.m. EDT (2:56 a.m. PDT) at the opening of a short 30-second launch window.

NASA TV will broadcast the launch live with countdown commentary beginning at 3:45 a.m. EDT (12:45 a.m. PDT): http://www.nasa.gov/multimedia/nasatv/

The California weather prognosis is currently outstanding at 100 percent ‘GO’ for favorable weather conditions at launch time.

The two stage Delta II 7320-10 launch vehicle is 8 ft in diameter and approximately 128 ft tall. It is equipped with a trio of strap on solid rocket motors. This marks the 152nd Delta II launch overall and the 51st for NASA since 1989.

The last time a Delta II rocket flew was nearly three years ago in October 2011 from Vandenberg for the Suomi National Polar-Orbiting Partnership (NPP) weather satellite.

The final Delta II launch from Cape Canaveral on Sept. 10, 2011 boosted NASA’s twin GRAIL gravity mapping probes to the Moon.

The Delta II will boost OCO-2 into a 438-mile (705-kilometer) altitude, near-polar orbit. Spacecraft separation from the rocket occurs 56 minutes 15 seconds after launch.

It will lead a constellation of five other international Earth monitoring satellites that circle Earth.

The phone-booth sized OCO-2 was built by Orbital Sciences and is a replacement for the original OCO which was destroyed during the failed launch of a Taurus XL rocket from Vandenberg back in February 2009 when the payload fairing failed to open properly.

OCO-2 is the second of NASA’s five new Earth science missions launching in 2014 and is designed to operate for at least two years during its primary mission. It follows the successful blastoff of the joint NASA/JAXA Global Precipitation Measurement (GPM) Core Observatory satellite on Feb 27.

Orbiting Carbon Observatory-2 (OCO-2) mission will provide a global picture of the human and natural sources of carbon dioxide, as well as their “sinks,” the natural ocean and land processes by which carbon dioxide is pulled out of Earth’s atmosphere and stored, according to NASA..

“Carbon dioxide in the atmosphere plays a critical role in our planet’s energy balance and is a key factor in understanding how our climate is changing,” said Michael Freilich, director of NASA’s Earth Science Division in Washington.

“With the OCO-2 mission, NASA will be contributing an important new source of global observations to the scientific challenge of better understanding our Earth and its future.”

It will record around 100,000 CO2 measurements around the world every day and help determine its source and fate in an effort to understand how human activities impact climate change and how we can mitigate its effects.

At the dawn of the Industrial Revolution, there were about 280 parts per million (ppm) of carbon dioxide in Earth’s atmosphere. As of today the CO2 level has risen to about 400 parts per million.

NASA’s Curiosity rover celebrated a milestone anniversary today, June 24 – 1 Martian Year on Mars!

A Martian year is equivalent to 687 Earth days, or nearly two Earth years.

NASA marked the illustrious achievement with the release of a new ‘selfie’ captured recently while drilling deep into the Red Planet to unlock the secrets of Mars hidden past eons ago when the planet was far warmer and wetter and more conducive to the origin of life.

Curiosity’s new self-portrait was taken at the ‘Windjana’ Drilling Site in April and May 2014 using the Mars Hand Lens Imager (MAHLI) camera at the end of the robotic arm.

As of today the 1 ton rover has been exploring the alien surface for a full Martian year since her nail biting touchdown inside Gale Crater on Aug. 5, 2012 – using the unprecedented sky crane maneuver which culminated in a rocket assisted touchdown astride a humongous mountain named Mount Sharp.

Mount Sharp dominates the center of Gale Crater and reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Rainier.

During Mars Year 1 on Mars, Earth’s metallic emissary has already accomplished her primary objective of discovering a habitable zone on the Red Planet that contains the chemical ingredients necessary to support microbial life in the ancient past.

During 2013, Curiosity conducted the first two drill campaigns at the ‘John Klein’ and ‘Cumberland’ outcrop targets inside Yellowknife Bay. They were both mudstone rock outcrops and the interiors were markedly different in color and much lighter compared to the new drill site at ‘Windjana’ into a slab of red, sandstone rock.

The fresh bore hole was drilled into the “Windjana” rock outcrop on May 5, 2014, Sol 621, at the base of Mount Remarkable at a science stopping point called “The Kimberley Waypoint.”

It was 0.63 inch (1.6 centimeters) in diameter and about 2.6 inches (6.5 centimeters) deep and resulted in a mound of dark grey colored drill tailings piled around.

Windjana lies some 2.5 miles (4 kilometers) southwest of Yellowknife Bay.

Curiosity has successfully delivered pulverized and sieved samples from all three drill sites to the pair of onboard miniaturized chemistry labs; the Chemistry and Mineralogy instrument (CheMin) and the Sample Analysis at Mars instrument (SAM) – for chemical and compositional analysis.

It was through the results of the SAM and CheMin analysis and the discovery of clay minerals that the science team was able to determine that this area on the floor of Gale Crater is a habitable zone.

“Windjana has more magnetite than previous samples we’ve analyzed,” said David Blake, principal investigator for Curiosity’s Chemistry and Mineralogy (CheMin) instrument at NASA’s Ames Research Center, Moffett Field, California, in a statement.

“A key question is whether this magnetite is a component of the original basalt or resulted from later processes, such as would happen in water-soaked basaltic sediments. The answer is important to our understanding of habitability and the nature of the early-Mars environment.”

Chemical analysis and further sample deliveries are in progress as NASA’s rover is ‘on the go’ to simultaneously maximize movement and research activities.

The lower reaches of Mount Sharp are the rovers ultimate goal because the sedimentary layers are believed to hold caches of water altered minerals based on high resolution measurements obtained by the CRISM spectrometer aboard NASA’s powerful Martian ‘Spysat’ – the Mars Reconnaissance Orbiter (MRO) – soaring overhead.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the dunes at the foothills of Mount Sharp sometime later this year.

Driving, Driving, Driving – Curiosity’s Top Priority on the Road to Mysterious Mount Sharp

Driving, Driving, Driving – that’s the number one priority for NASA’s rover Curiosity as she traverses across the floor of Gale Crater towards towering Mount Sharp on an expedition in search of the chemical ingredients of life that could support Martian microbes if they ever existed.

See our photo mosaics above and below showing the 1 ton rover trundling across the alien terrain of Mars – our Solar Systems most Earth-like planet and leaving behind dramatic wheel tracks in her wake.

“The top priority for MSL continues to be the traverse toward the base of Mt. Sharp,” wrote science team member Ken Herkenhoff in a mission update.

Curiosity has been on the move since mid-May after successfully completing her 3rd Martian drill campaign at a science stopping point called “The Kimberley” where she bored a fresh hole into the ‘Windjama’ rock target on May 5, Sol 621 at the base of Mount Remarkable.

“Progress has been good since leaving The Kimberley,” Herkenhoff added.

Investigating mysterious Mount Sharp is why Gale Crater was chosen as the landing site because the mountain holds clues to the habitability of the Red Planet.

Mars was far wetter and warmer – and more conducive to the origin of life – billions of years ago.

The six-wheeled rover has been traveling with all deliberate speed to get to the mountain with minimal science along the way.

“[Curiosity conducted] a 129-meter drive on Sol 662 (June 17),” says Herkenhoff.

“We successfully planned a rapid traverse sol last week, in which scientific observations are limited in favor of maximizing drive distance.”

Curiosity is driving on a path towards the ‘Murray Buttes’ – which lies across the dark and potentially treacherous dunes on the right side of Mount Sharp as seen in our photo mosaic above from Sol 651.

She will eventually ascend the mountain at the ‘Murray Buttes’ after the team locates a spot to carefully cross the sand dunes.

The fresh hole drilled into “Windjana” was 0.63 inch (1.6 centimeters) in diameter and about 2.6 inches (6.5 centimeters) deep and resulted in a mound of dark grey colored drill tailings piled around. It looked different from the initial two holes drilled at Yellowknife Bay in the spring of 2013.

Windjana was a cold red slab of enticing bumpy textures of Martian sandstone located at the base of ‘Mount Remarkable’ within the “The Kimberley Waypoint” region.

The first two drill campaigns involved boring into mudstone outcrops at Yellowknife Bay.

Windjana lies some 2.5 miles (4 kilometers) southwest of Yellowknife Bay.

Curiosity then successfully delivered pulverized and sieved samples to the pair of onboard miniaturized chemistry labs; the Chemistry and Mineralogy instrument (CheMin) and the Sample Analysis at Mars instrument (SAM) – for chemical and compositional analysis.

Chemical analysis and further sample deliveries are in progress as NASA’s rover is ‘on the go’ to simultaneously maximize movement and research activities.

The science and engineering team has deliberately altered the robots path towards the foothills of Mount Sharp which reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Ranier.

The team decided to follow a new path to the mountain with smoother terrain after sharp edged rocks caused significant damage in the form of dents and holes to the robots 20 inch wide aluminum wheels.

The wheel punctures happened faster than expected in 2013 and earlier this year.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the dunes at the foothills of Mount Sharp sometime later this year.

To date, Curiosity’s odometer totals over 7.9 kilometers (4.9 miles) since landing inside Gale Crater on Mars in August 2012. She has taken over 159,000 images.

India’s 1st Mars Mission Celebrates 100 Days and 100 Million Kilometers from Mars Orbit Insertion Firing – Cruising Right behind NASA’s MAVEN

India’s Mars Orbiter Mission (MOM) marked 100 days out from Mars on June 16, 2014 and the Mars Orbit Insertion engine firing when it arrives at the Red Planet on September 24, 2014 after its 10 month interplanetary journey. Credit ISRO

India’s inaugural voyager to the Red Planet, the Mars Orbiter Mission or MOM, has just celebrated 100 days and 100 million kilometers out from Mars on June 16, until the crucial Mars Orbital Insertion (MOI) engine firing that will culminate in a historic rendezvous on September 24, 2014.

MOM is cruising right behind NASA’s MAVEN orbiter which celebrated 100 days out from Mars on Friday the 13th of June. MAVEN arrives about 48 hours ahead of MOM on September 21, 2014.

After streaking through space for some ten and a half months, the 1,350 kilogram (2,980 pound) MOM probe will fire its 440 Newton liquid fueled main engine to brake into orbit around the Red Planet on September 24, 2014 – where she will study the atmosphere and sniff for signals of methane.

Working together, MOM and MAVEN will revolutionize our understanding of Mars atmosphere, dramatic climatic history and potential for habitability.

The do or die MOI burn on September 24, 2014 places MOM into an 377 km x 80,000 km elliptical orbit around Mars.

Trans Mars Injection (TMI), carried out on Dec 01, 2013 at 00:49 hrs (IST) has moved the spacecraft in the Mars Transfer Trajectory (MTT). With TMI the Earth orbiting phase of the spacecraft ended and the spacecraft is now on a course to encounter Mars after a journey of about 10 months around the Sun. Credit: ISRO

MOM was designed and developed by the Indian Space Research Organization’s (ISRO) at a cost of $69 Million and marks India’s maiden foray into interplanetary flight.

But before reaching Mars, mission navigators must keep the craft meticulously on course on its heliocentric trajectory from Earth to Mars through a series of in flight Trajectory Correction Maneuvers (TMSs).

The second TCM was just successfully performed on June 11 by firing the spacecraft’s 22 Newton thrusters for a duration of 16 seconds. TCM-1 was conducted on December 11, 2013 by firing the 22 Newton Thrusters for 40.5 seconds. Two additional TCM firings are planned in August and September 2014.

To date the probe has flown about 70% of the way to Mars, traveling about 466 million kilometers out of a total of 680 million kilometers (400 million miles) overall, with about 95 days to go. One way radio signals to Earth take approximately 340 seconds.

MOM reached the halfway mark to Mars on April 9, 2014.

ISRO reports the spacecraft and its five science instruments are healthy. It is being continuously monitored by the Indian Deep Space Network (IDSN) and NASA JPL’s Deep Space Network (DSN).

MOM’s journey began with a picture perfect blast off on Nov. 5, 2013 from India’s spaceport at the Satish Dhawan Space Centre, Sriharikota, atop the nations indigenous four stage Polar Satellite Launch Vehicle (PSLV) which placed the probe into its initial Earth parking orbit.

A series of six subsequent orbit raising maneuvers ultimately culminated with a liquid fueled main engine firing on Dec. 1, 2013 for the Trans Mars Injection(TMI) maneuver that successfully placed MOM on a heliocentric elliptical trajectory to the Red Planet.

If all goes well, India will join an elite club of only four who have launched probes that successfully investigated the Red Planet from orbit or the surface – following the Soviet Union, the United States and the European Space Agency (ESA).

Both MAVEN and MOM’s goal is to study the Martian atmosphere, unlock the mysteries of its current atmosphere and determine how, why and when the atmosphere and liquid water was lost – and how this transformed Mars climate into its cold, desiccated state of today.

Together, MOM and MAVEN will fortify Earth’s invasion fleet at Mars. They join 3 current orbiters from NASA and ESA as well as NASA’s pair of sister surface rovers Curiosity and Opportunity.

Although they were developed independently and have different suites of scientific instruments, the MAVEN and MOM science teams will “work together” to unlock the secrets of Mars atmosphere and climate history, MAVEN’s top scientist told Universe Today.

“We have had some discussions with their science team, and there are some overlapping objectives,” Bruce Jakosky told me. Jakosky is MAVEN’s principal Investigator from the University of Colorado at Boulder.

“At the point where we [MAVEN and MOM] are both in orbit collecting data we do plan to collaborate and work together with the data jointly,” Jakosky said.

Opportunity Peers Out from ‘Pillinger Point’ – Honoring British Beagle 2 Mars Scientist Where Ancient Water Flowed

Opportunity Mars rover peers into vast Endeavour Crater from Pillinger Point mountain ridge named in honor of Colin Pillinger, the Principal Investigator for the British Beagle 2 lander built to search for life on Mars.

NASA’s decade old Opportunity rover has reached a long sought after region of aluminum-rich clay mineral outcrops at a new Endeavour crater ridge now “named ‘Pillinger Point’ after Colin Pillinger the Principal Investigator for the [British] Beagle 2 Mars lander”, Prof. Ray Arvidson, Deputy Principal Investigator for the rover, told Universe Today exclusively. See above the spectacular panoramic view from ‘Pillinger Point’ – where ancient water once flowed billions of year ago.

The Beagle 2 lander was built to search for signs of life on Mars.

The Mars Exploration Rover (MER) team named the noteworthy ridge in honor of Prof. Colin Pillinger – a British planetary scientist at the Open University in Milton Keynes, who passed away at the age of 70 on May 7, 2014.

‘Pillinger Point’ is a scientifically bountiful place possessing both clay mineral outcrops and mineral veins where “waters came up through the cracks”, Arvidson explained to me.

Since water is a prerequisite for life as we know it, this is a truly fitting tribute to name Opportunity’s current exploration site ‘Pillinger Point’ after Prof. Pillinger.

See our new photo mosaic above captured by Opportunity peering out from ‘Pillinger Point’ ridge on June 5, 2014 (Sol 3684) and showing a panoramic view around the eroded mountain ridge and into vast Endeavour crater.

The gigantic crater spans 14 miles (22 kilometers) in diameter.

See below our Opportunity 10 Year traverse map showing the location of Pillinger Point along the segmented rim of Endeavour crater.

British planetary scientist Colin Pillinger with the Beagle 2 lander.

Pillinger Point is situated south of Solander Point and Murray Ridge along the western rim of Endeavour in a region with caches of clay minerals indicative of an ancient Martian habitable zone.

For the past several months, the six wheeled robot has been trekking southwards from Solander towards the exposures of aluminum-rich clays – now named Pillinger Point- detected from orbit by the CRISM spectrometer aboard NASA’s powerful Martian ‘Spysat’ – the Mars Reconnaissance Orbiter (MRO) – while gathering context data at rock outcrops along the winding way.

“We are about 3/5 of the way along the outcrops that show an Al-OH [aluminum-hydroxl] montmorillonite [clay mineral] signature at 2.2 micrometers from CRISM along track oversampled data,” Arvidson told me.

“We have another ~160 meters to go before reaching a break in the outcrops and a broad valley.”

The rover mission scientists ultimate goal is travel even further south to ‘Cape Tribulation’ which holds a motherlode of the ‘phyllosilicate’ clay minerals based on extensive CRISM measurements accomplished earlier at Arvidson’s direction.

“The idea is to characterize the outcrops as we go and then once we reach the valley travel quickly to Cape Tribulation and the smectite valley, which is still ~2 km to the south of the present rover location,” Arvidson explained.

Mars Express and Beagle 2 were launched in 2003, the same year as NASA’s twin rovers Spirit and Opportunity, on their interplanetary voyages to help unlock the mysteries of Mars potential for supporting microbial life forms.

Pillinger was the driving force behind the British built Beagle 2 lander which flew to the Red Planet piggybacked on ESA’s Mars Express orbiter. Unfortunately Beagle 2 vanished without a trace after being deployed from the orbiter on Dec. 19, 2003 with an expected air bag assisted landing on Christmas Day, Dec. 25, 2003.

In an obituary by the BBC, Dr David Parker, the chief executive of the UK Space Agency, said that Prof. Pillinger had played a critical role in raising the profile of the British space programme and had inspired “young people to dream big dreams”.

During his distinguished career Pillinger also analyzed lunar rock samples from NASA’s Apollo moon landing missions and worked on ESA’s Rosetta mission.

“It’s important to note that Colin’s contribution to planetary science goes back to working on Moon samples from Apollo, as well as his work on meteorites,” Dr Parker told the BBC.

Today, June 16, marks Opportunity’s 3696th Sol or Martian Day roving Mars – compared to a warranty of just 90 Sols.

So far she has snapped over 193,400 amazing images on the first overland expedition across the Red Planet.

Her total odometry stands at over 24.51 miles (39.44 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.

Meanwhile on the opposite side of Mars, Opportunity’s younger sister rover Curiosity is trekking towards gigantic Mount Sharp after drilling into her 3rd Red Planet rock at Kimberley.
