Liftoff of the ExoMars 2018 rover mission currently under development jointly by Europe and Russia has just been postponed for two years to 2020, according to an announcement today, May 2, from the European Space Agency (ESA) and the Russian space agency Roscosmos.

The delay was forced by a variety of technical and funding issues that ate up the schedule margin to enable a successful outcome for what will be Europe’s first Mars rover. The goal is to search for signs of life.

“Taking into account the delays in European and Russian industrial activities and deliveries of the scientific payload, a launch in 2020 would be the best solution,” ESA explained in a statement today.

The ambitious ExoMars rover is the second of two joint Euro-Russian missions to explore the Red Planet. It is equipped with an ESA deep driller and a NASA instrument to search for preserved organic molecules.

The first mission known as ExoMars 2016 was successfully launched last month from the Baikonur Cosmodrome in Kazakhstan atop a Russian Proton-M rocket on March 14.

The renamed ExoMars 2020 mission involves a European-led rover and a Russian-led surface platform and is also slated to blastoff on an Russian Proton rocket.

Roscosmos and ESA jointly decided to move the launch to the next available Mars launch window in July 2020. The costs associated with the delay are not known.

The delay means that the Euro-Russian rover mission will launch the same year as NASA’s 2020 rover.

The rover is being built by prime contractor Airbus Defense and Space in Stevenage, England.

The descent module and surface science package are provided by Roscosmos with some contributions by ESA.

Recognizing the potential for a delay, ESA and Roscosmos set up a tiger team in late 2015 to assess the best options.

“Russian and European experts made their best efforts to meet the 2018 launch schedule for the mission, and in late 2015, a dedicated ESA-Roscosmos Tiger Team, also including Russian and European industries, initiated an analysis of all possible solutions to recover schedule delays and accommodate schedule contingencies,” said ESA in the statement.

The tiger team reported their results to ESA Director General Johann-Dietrich Woerner and Roscosmos Director General Igor Komarov.

Woerner and Komarov then “jointly decided to move the launch to the next available Mars launch window in July 2020, and tasked their project teams to develop, in cooperation with the industrial contactors, a new baseline schedule aiming towards a 2020 launch. Additional measures will also be taken to maintain close control over the activities on both sides up to launch.”

The ExoMars 2016 interplanetary mission is comprised of the Trace Gas Orbiter (TGO) and the Schiaparelli lander. The spacecraft are due to arrive at Mars in October 2016.

The goal of TGO is to search for possible signatures of life in the form of trace amounts of atmospheric methane on the Red Planet.

The main purpose of Schiaparelli is to demonstrate key entry, descent, and landing technologies for the follow on 2nd ExoMars mission that will land the first European rover on the Red Planet.

The now planned 2020 ExoMars mission will deliver an advanced rover to the Red Planet’s surface. It is equipped with the first ever deep driller that can collect samples to depths of 2 meters (seven feet) where the environment is shielded from the harsh conditions on the surface – namely the constant bombardment of cosmic radiation and the presence of strong oxidants like perchlorates that can destroy organic molecules.

ExoMars was originally a joint NASA/ESA project.

But thanks to hefty cuts to NASA’s budget by Washington DC politicians, NASA was forced to terminate the agencies involvement after several years of extremely detailed work and withdraw from participation as a full partner in the exciting ExoMars missions.

NASA is still providing the critical MOMA science instrument that will search for organic molecules.

Thereafter Russia agreed to take NASA’s place and provide the much needed funding and rockets for the pair of launches in March 2016 and May 2018.

TGO will also help search for safe landing sites for the ExoMars 2020 lander and serve as the all important data communication relay station sending signals and science from the rover and surface science platform back to Earth.

ExoMars 2016 is Europe’s most advanced mission to Mars and joins Europe’s still operating Mars Express Orbiter (MEX), which arrived back in 2004, as well as a fleet of NASA and Indian probes.

The Trace Gas Orbiter (TGO) and Schiaparelli lander arrive at Mars on October 19, 2016.

NASA’s Curiosity Mars Science Laboratory (MSL) rover successfully bored a brand new hole in Mars at a tantalizing sandstone outcrop in the ‘Lubango’ fracture zone this past weekend on Sol 1320, Apr. 23, and is now carefully analyzing the shaken and sieved drill tailings for clues to Mars watery past atop the Naukluft Plateau.

“We have a new drill hole on Mars!” reported Ken Herkenhoff, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update.

“All of the activities planned for last weekend have completed successfully.”

“Lubango” counts as the 10th drilling campaign since the one ton rover safely touched down on the Red Planet some 44 months ago inside the targeted Gale Crater landing site, following the nailbiting and never before used ‘sky crane’ maneuver.

After transferring the cored sample to the CHIMRA instrument for sieving it, a portion of the less than 0.15 mm filtered material was successfully delivered this week to the CheMin miniaturized chemistry lab situated in the rovers belly.

CheMin is now analyzing the sample and will return mineralogical data back to scientists on earth for interpretation.

The science team selected Lubango as the robots 10th drill target after determining that it was altered sandstone bedrock and had an unusually high silica content based on analyses carried out using the mast mounted ChemCam laser instrument.

Indeed the rover had already driven away for further scouting and the team then decided to return to Lubango after examining the ChemCam results. They determined the ChemCam and other data observation were encouraging enough – regarding how best to sample both altered and unaltered Stimson bedrock – to change course and drive backwards.

Lubango sits along a fracture in an area that the team dubs the Stimson formation, which is located on the lower slopes of humongous Mount Sharp inside Gale Crater.

This mid-afternoon, 360-degree panorama was acquired by the Mast Camera (Mastcam) on NASA's Curiosity Mars rover on April 4, 2016, as part of long-term campaign to document the context and details of the geology and landforms along Curiosity's traverse since landing in August 2012.

Since early March, the rover has been traversing along a rugged region dubbed the Naukluft Plateau.

“The team decided to drill near this fracture to better understand both the altered and unaltered Stimson bedrock,” noted Herkenhoff.

See our photo mosaic above showing the geologically exciting terrain surrounding Curiosity with its outstretched 7-foot-long (2-meter-long) robotic arm after completing the Lubango drill campaign on Sol 1320. The mosaic was created by the imaging team of Ken Kremer and Marco Di Lorenzo.

Its again abundantly clear from the images that beneath the rusty veneer of the Red Planet lies a greyish interior preserving the secrets of Mars ancient climate history.

The team then commanded Curiosity to dump the unsieved portion of the sample onto the ground and examine the leftover drill tailing residues with the Mastcam, Navcam, MAHLI multispectral characterization cameras and the APXS spectrometer. ChemCam is also being used to fire laser shots in the wall of the drill hole to make additional chemical measurements.

To complement the data from Lubango, scientists are now looking around the area for a suitable target of unaltered Stimson bedrock as the 11th drill target.

“The color information provided by Mastcam is really helpful in distinguishing altered versus unaltered bedrock,” explained MSL science team member Lauren Edgar, Research Geologist at the USGS Astrogeology Science Center, in a mission update.

The ChemCam laser has already shot at the spot dubbed “Oshikati,” a potential target for the next drilling campaign.

“On Sunday we will drive to our next drilling location, which is on a nearby patch of normal-looking Stimson sandstone,” wrote Ryan Anderson, planetary scientist at the USGS Astrogeology Science Center and a member of the ChemCam team on MSL in today’s (Apr. 28) mission update.

As time permits, the Navcam imager is also being used to search for dust devils.

As I reported here, Opportunity recently detected a beautiful looking dust devil on the floor of Endeavour crater on April 1. Dust devil detections by the NASA rovers are relatively rare.

Curiosity has been driving to the edge of the Naukluft Plateau to reach the interesting fracture zone seen in orbital data gathered from NASA’s Mars orbiter spacecraft.

The rover is almost finished crossing the Naukluft Plateau which is “the most rugged and difficult-to-navigate terrain encountered during the mission’s 44 months on Mars,” says NASA.

Prior to climbing onto the Naukluft Plateau the rover spent several weeks investigating sand dunes including the two story tall Namib dune.

SpaceX Announces Plan to Launch Private Dragon Mission to Mars in 2018

SpaceX announced plans today, April 27, for the first ever private mission to Mars which involves sending an uncrewed version of the firms Dragon spacecraft to accomplish a propulsive soft landing – and to launch it as soon as 2018 including certain technical assistance from NASA.

Under a newly signed space act agreement with NASA, the agency will provide technical support to SpaceX with respect to Mars landing technologies for the new spacecraft known as a ‘Red Dragon’ and possibly also for science activities.

“SpaceX is planning to send Dragons to Mars as early as 2018,” the company posted in a brief announcement today on Facebook and other social media about the history making endeavor.

The 2018 commercial Mars mission involves launching the ‘Red Dragon’ – also known as Dragon 2 – on the SpaceX Falcon Heavy rocket from Launch Pad 39A at NASA’s Kennedy Space Center in Florida. It’s a prelude to eventual human missions.

The Red Dragon initiative is a commercial endeavor that’s privately funded by SpaceX and does not include any funding from NASA. The agreement with NASA specifically states there is “no-exchange-of-funds.”

As of today, the identity and scope of any potential science payload is undefined and yet to be determined.

Hopefully it will include a diverse suite of exciting research instruments from NASA, or other entities, such as high powered cameras and spectrometers characterizing the Martian surface, atmosphere and environment.

SpaceX CEO and billionaire founder Elon Musk has previously stated his space exploration goals involve helping to create a Mars colony which would ultimately lead to establishing a human ‘City on Mars.’

Musk is also moving full speed ahead with his goal of radically slashing the cost of access to space by recovering a pair of SpaceX Falcon 9 first stage boosters via successful upright propulsive landings on land and at sea – earlier this month and in Dec. 2015.

The 2018 liftoff campaign marks a significant step towards fulfilling Musk’s Red Planet vision. But we’ll have to wait another 5 months for concrete details.

“Red Dragon missions to Mars will also help inform the overall Mars colonization architecture that SpaceX will reveal later this year,” SpaceX noted.

Musk plans to reveal the details of the Mars colonization architecture later this year at the International Astronautical Congress (IAC) being held in Guadalajara, Mexico from September 26 to 30, 2016.

Landing on Mars is not easy. To date only NASA has successfully soft landed probes on Mars that returned significant volumes of useful science data.

In the meantime a few details about the SpaceX Red Dragon have emerged.

The main goal is to propulsively land something 5-10 times the size of anything previously landed before.

“These missions will help demonstrate the technologies needed to land large payloads propulsively on Mars,” SpaceX further posted.

NASA’s 1 ton Curiosity rover is the heaviest spaceship to touchdown on the Red Planet to date.

As part of NASA’s agency wide goal to send American astronauts on a human ‘Journey to Mars’ in the 2030s, NASA will work with SpaceX on some aspects of the Red Dragon initiative to further the agency’s efforts.

According to an amended space act agreement signed yesterday jointly by NASA and SpaceX officials – that originally dates back to November 2014 – this mainly involves technical support from NASA and exchanging entry, descent and landing (EDL) technology, deep space communications, telemetry and navigation support, hardware advice, and interplanetary mission and planetary protection advice and consultation.

“We’re particularly excited about an upcoming SpaceX project that would build upon a current “no-exchange-of-funds” agreement we have with the company,” NASA Deputy Administrator Dava Newman wrote in a NASA blog post today.

“In exchange for Martian entry, descent, and landing data from SpaceX, NASA will offer technical support for the firm’s plan to attempt to land an uncrewed Dragon 2 spacecraft on Mars.”

“This collaboration could provide valuable entry, descent and landing data to NASA for our journey to Mars, while providing support to American industry,” NASA noted in a statement.

The amended agreement with NASA also makes mention of sharing “Mars Science Data.”

As of today, the identity, scope and weight of any potential science payload is undefined and yet to be determined.

Perhaps it could involve a suite of science instruments from NASA, or other entities, such as cameras and spectrometers characterizing various aspects of the Martian environment.

In the case of NASA, the joint agreement states that data collected with NASA assets is to be released within a period not to exceed 6 months and published where practical in scientific journals.

The Red Dragon envisioned for blastoff to the Red Planet as soon as 2018 would launch with no crew on board on a critical path finding test flight that would eventually pave the way for sending humans to Mars – and elsewhere in the solar system.

“Red Dragon Mars mission is the first test flight,” said Musk.

“Dragon 2 is designed to be able to land anywhere in the solar system.”

However, the Dragon 2 alone is far too small for a round trip mission to Mars – lasting some three years or more.

“But wouldn’t recommend transporting astronauts beyond Earth-moon region,” tweeted Musk.

“Wouldn’t be fun for longer journeys. Internal volume ~size of SUV.”

Furthermore, for crewed missions it would also have to be supplemented with additional modules for habitation, propulsion, cargo, science, communications and more. Think ‘The Martian’ movie to get a realistic idea of the complexity and time involved.

Red Dragon’s blastoff from KSC pad 39A is slated to take place during the Mars launch window opening during April and May 2018.

The inaugural liftoff of the Falcon Heavy is currently scheduled for late 2016 after several years postponement.

If all goes well, Red Dragon could travel to Mars at roughly the same time as NASA’s next Mission to Mars – namely the InSight science lander, which will study the planets deep interior with a package of seismometer and heat flow instruments.

InSight’s launch on a United Launch Alliance Atlas V is targeting a launch window that begins May 5, 2018, with a Mars landing scheduled for Nov. 26, 2018. Liftoff was delayed from this year due to a flaw in the French-built seismometer.

Whoever wants to land on Mars also has to factor in the relevant International treaties regarding ‘Planetary Protection’ requirements.

Wherever the possibility for life exists, the worlds space agency’s who are treaty signatories, including NASA, are bound to adhere to protocols limiting contamination by life forms from Earth.

SpaceX intends to take planetary protection seriously. Under the joint agreement, SpaceX is working with relevant NASA officials to ensure proper planetary protection procedures are followed. One of the areas of collaboration with NASA is for them to advise SpaceX in the development a Planetary Protection Plan (PPP) and assist with the implementation of a PPP including identifying existing software/tools.

Red Dragon is derived from the SpaceX crew Dragon vehicle currently being developed under contract for NASA’s Commercial Crew Program (CCP) to transport American astronauts back and forth to low Earth orbit and the International Space Station (ISS).

SpaceX and Boeing were awarded commercial crew contracts from NASA back in September 2014.

Both firms hope to launch unmanned and manned test flights of their SpaceX Crew Dragon and Boeing CST-100 Starliner spacecraft to the ISS starting sometime in 2017.

The crew Dragon is also an advanced descendent of the original unmanned cargo Dragon that has ferried tons of science experiments and essential supplies to the ISS since 2012.

To enable propulsive landings, SpaceX recently conducted hover tests using a Dragon 2 equipped with eight side-mounted SuperDraco engines at their development testing facility in McGregor, TX.

These are “Key for Mars landing,” SpaceX wrote.

“We are closer than ever before to sending American astronauts to Mars than anyone, anywhere, at any time has ever been,” Newman states.

New Highest Resolution Images Of Long-Lost Beagle 2 Lander

We like to focus on successful space missions and celebrate what those successes add to our knowledge. But, obviously, not all missions are completely successful. And since some missions are at such huge distances from Earth, their fate can remain a mystery.

This was true of the Beagle 2 Lander, until recently.

The Beagle 2 was a UK contribution to the ESA’s Mars Express mission, launched in 2003. Mars Express consisted of two components; the Mars Express Orbiter and the Beagle 2 Lander. The mission arrived at Mars in December 2003, when the Beagle 2 separated from the orbiter and landed on the Martian surface.

Beagle 2’s destination was Isidis Planitia, a vast sedimentary basin. Beagle 2 was supposed to operate for 180 days, with a possible extension up to one Martian year. But the ESA was unable to contact the lander after several attempts, and in February 2004, the ESA declared the mission lost.

The Beagle 2, named after the ship that Darwin took on his famous voyage, had some solid science goals in mind. It was going to study the geology, mineralogy, and the geochemistry of the landing site, and also the physical properties of the atmosphere and Mars’ surface. It was also going to study the Martian meteorology and climate, and search for biosignatures. But all that was lost.

There was lots of conjecture, but the Beagle 2’s fate was a mystery.

Now, thanks to a new method of ‘stacking and matching’ photos of the Martian surface, which results in higher resolution images than previously possible, the likely fate of the Beagle 2 is known. It appears that the spacecraft landed softly as planned, but that solar panels failed to deploy properly. This not only starved the lander of electrical power, but blocked the craft’s antenna from functioning. This is why no signal was ever received from Beagle 2.

It took quite a bit of sleuthing to find the Beagle 2. The MRO has used its High Resolution Imaging Science Experiment (HiRise) camera to search for other craft on the surface of Mars, but the Beagle 2 was harder to find. It never sent even a brief signal after touchdown, which would have made it much easier to locate.

Adding to the difficulty is the huge landing area the Beagle 2 had. Beagle 2’s landing site at the time of its launch was an ellipse 170 km by 100 km in the Isidis Planitia. That’s an enormous area in which to locate a spacecraft that’s less than a few meters across once deployed, with a camera that has an image scale of about 0.2m, (10 inches).

The MRO has been using its HiRise to look for Beagle 2 since it was lost. As it went about the business of its science objectives, it captured occasional images of the Beagle 2’s landing site. Eventually, the lander was identified by Michael Croon, a former member of the ESA’s Mars Express Orbiter team. In HiRise images from February 2013 and June 2014, Croon found visual evidence of the lander and its entry and descent components.

The puzzling thing was that the image seemed to shift around in different photos. This could be because the lander deployed its solar panels like flower petals arranged around the center. The panels will reflect light differently in different lighting conditions, which could make the lander appear to change location in subsequent photos. If Beagle 2 is sitting on an uneven surface, that could add to the illusion.

The HiRise images are consistent with the idea that the panels failed to deploy, and that also makes sense if the panels blocked the antenna from operating. It’s also possible that the sun glinting off the panels only makes it appear that not all of them opened.

But what’s bad news for Beagle 2 is good news for the human endeavour to study Mars. The new technique of combining images of the surface of Mars yields photos with 5 times the resolution that MRO can provide. This will make selecting landing sites for future missions much easier, and will also contribute to the science objectives of the MRO itself.

The Mars Express Orbiter is still in operation above Mars, and has been for over 12 years. Among its achievements are the detection of water ice in Mars’ South Polar cap and the discovery of methane in the atmosphere of Mars. The orbiter also performed the closest-ever flyby of Mars’ moon Phobos.

Fans of Elon Musk and commercial space exploration are buzzing over the news! Back in 2002, when Musk first established the private aerospace company SpaceX, he did so with the intent of creating the technologies needed to reduce the cost of space transportation and enable crewed missions to Mars. And for the past few years, industry and the general public alike have been waiting on him to say when missions to Mars might truly begin.

Earlier this morning, Elon Musk did just that, when he tweeted from his company account that SpaceX plans to send a Dragon capsule to Mars by 2018. Despite talking about his eventual plans to mount crewed missions to Mars in the coming decades, and to even build a colony there, this is the first time that a specific date has been attached to any plans.

What was also indicated in the announcement was that the missions would be built around the “Red Dragon” mission architecture. As a modified, unmanned version of the Dragon capsule, this craft was conceived back in 2013 and 2015 as part of the NASA Discovery Program – specifically for Mission 13, a series of concepts which are scheduled to launch sometime in 2022.

Though the idea was never submitted to NASA, SpaceX has kept them on hand as part of a proposed low-cost Mars lander mission that would deploy a sample-return rover to the Martian surface. The mission will be deployed using a Falcon Heavy rocket, based on the mission profile and the illustrations that accompanied the announcement.

This mission would not only demonstrate SpaceX’s ability to procure samples from the Martian environment and bring them back to Earth – something that only federal space agencies like NASA have been able to do so far – but also test techniques and equipment that human crews will be using to enter the Martian atmosphere.

And if all goes well, we can expect that Musk will push forward with his plans for both crewed missions, and the development of all the necessary architecture to being work on his Mars Colonial Transporter, which he hopes to use to begin ferrying people to Mars to build his planned colony.

Stay tuned for more in-depth analysis of this announcement from our resident expert, Ken Kremer!

Spaceflight Will Give You The Body Of An Elderly Alcoholic Shut In

At least, that was what the results of a recent study conducted by the University of Colorado’s Anschutz Medical Campus suggest. After examining a group of test mice that spent two weeks in space aboard STS-135 – the final mission of NASA’s space shuttle program – they concluded that spending prolonged periods of time in space could in fact result liver damage.

For some time now, scientists have understood that exposure to zero-gravity or micro-gravity environments comes with its share of health effects. But so far, the research has been largely confined to other areas of the human body. Understanding the effects it has on internal organs and other aspects of one’s health are of extreme importance as NASA begins preparations for a crewed mission to Mars.

Every year, the NASA Innovative Advanced Concepts (NIAC) program puts out the call to the general public, hoping to find better or entirely new aerospace architectures, systems, or mission ideas. As part of the Space Technology Mission Directorate, this program has been in operation since 1998, serving as a high-level entry point to entrepreneurs, innovators and researchers who want to contribute to human space exploration.

This year, thirteen concepts were chosen for Phase I of the NIAC program, ranging from reprogrammed microorganisms for Mars, a two-dimensional spacecraft that could de-orbit space debris, an analog rover for extreme environments, a robot that turn asteroids into spacecraft, and a next-generation exoplanet hunter. These proposals were awarded $100,000 each for a nine month period to assess the feasibility of their concept.

Sometimes, the best way to study Mars is to stay home. There’s no substitute for actual missions to Mars, but pieces of Mars have made the journey to Earth, and saved us the trip. Case in point: the treasure trove of Martian meteorites that NASA is gathering from Antarctica.

NASA scientists aren’t the first ones to find meteorites in the Earth’s polar regions. As early as the 9th century, people in the northern polar regions made use of iron from meteorites for tools and hunting weapons. The meteorite iron was traded from group to group over long distances. But for NASA, the hunt for meteorites is focused on Antarctica.

In Antarctica, the frigid temperatures preserve meteorites for a long time, which makes them valuable artifacts in the quest to understand Mars. Meteorites tend to accumulate in places where creeping glacial ice moves them to. When the ice meets a rock obstacle, the meteorites are deposited there, making them easier to find. Recently arrived meteorites are also easily spotted on the surface of the Antarctica ice.

The US began collecting meteorites in Antarctica in 1976, and to date more than 21,000 meteorites and meteorite fragments have been found. In fact, more of them are found in Antarctica than in the rest of the world combined. These meteorites are then shared with scientists around the world.

Collecting meteorites in Antarctica is not a walk in the park. It’s physically gruelling and hazardous work. Antarctica is not an easy environment to live and work in, and just surviving there takes planning and teamwork. But the scientific payoff is huge, which keeps NASA going back.

Meteorites from the Moon and other bodies also arrive on Earth, and are collected in Antarctica. They can tell scientists important things about the evolution and formation of the Solar System, the origin of organic chemical compounds necessary for life, and the origin of the planets themselves.

How Do Martian Meteorites Get To Earth?

A few things have to go right for a Martian meteorite to make it to Earth. First, a meteorite has to collide with Mars. That meteorite has to be big enough, and hit the surface of Mars with enough force, that rock from Mars is propelled off the surface with enough speed to escape Mars’ gravity.

After that, the meteor has to travel through space and avoid a thousand other fates, like being drawn to one of the other planets, or the Sun, by the gravitational pull of those bodies. Or being flung off into the far reaches of empty space, lost forever. Then, if it manages to make it to Earth, and be pulled in by Earthly gravity, it must be large enough to survive entry into Earth’s atmosphere.

The Science

Part of the scientific value in meteorites lies not in their source, but in the time that they were formed. Some meteorites have travelled through space for so long, they’re like time travellers. These ancient meteorites can tell scientists a lot about conditions in the early Solar System.

Meteorites from Mars tell scientists a few things. Since they’ve survived re-entry into Earth’s atmosphere, they can tell engineers about the dynamics of such a journey, and help inform spacecraft design. Since they contain chemical signatures and elements unique to Mars, they can also tell mission specialists things about surviving on Mars.

They can also provide clues to one of the greatest mysteries in space exploration: Did life exist on Mars? A Martian meteorite found in the Sahara desert in 2011 contained ten times the amount of water as other Martian meteorites, and added evidence to the idea that Mars was once a wet world, suitable for life.

NASA’s program to hunt for meteorites in Antarctica has been going strong for many years, and there’s really no reason to stop doing it, since this is the only way to get Martian samples into a laboratory. Each one they find is like a puzzle piece, and like a jigsaw puzzle, you never know which one will complete the big picture.

ExoMars Takes First Hi-Res Image With The Lens Cap On

It doesn’t exactly qualify as eye candy, but the first image from the ESA-Roscosmos ExoMars spacecraft is beautiful to behold in its own way. For most of us, a picture like this would mean something went horribly wrong with our camera. But as the first image from the spacecraft, it tells us that the camera and its pointing system are functioning properly.

ExoMars is a joint project between the European Space Agency and Roscosmos, the Russian Federal Space Agency. It’s an ambitious project, and consists of 2 separate launches. On March 14, 2016, the first launch took place, consisting of the Trace Gas Orbiter (TGO) and the stationary test lander called Schiaparelli, which will be delivered by the Martian surface by the TGO.

TGO will investigate methane sources on Mars, and act as a communications satellite for the lander. The test lander is trying out new landing technologies, which will help with the second launch, in 2020, when a mobile rover will be launched and landed on the Martian surface.

So far, all systems are go on the ExoMars craft during its voyage. “All systems have been activated and checked out, including power, communications, startrackers, guidance and navigation, all payloads and Schiaparelli, while the flight control team have become more comfortable operating this new and sophisticated spacecraft,” says Peter Schmitz, ESA’s Spacecraft Operations Manager.

Three days prior to reaching Mars, the Schiaparelli lander will separate from the TGO and begin its descent to the Martian surface. Though Schiaparelli is mostly designed to gather information about its descent and landing, it still will do some science. It has a small payload of instrument which will function for 2-8 days on the surface, studying the environment and returning the results to Earth.

The TGO will perform its own set of maneuvers, inserting itself into an elliptical orbit around Mars and then spending a year aero-braking in the Martian atmosphere. After that, the TGO will settle into a circular orbit about 400 km above the surface of Mars.

The TGO is hunting for methane, which is a chemical signature for life. It will also be studying the surface features of Mars.

Opportunity Discovers Dust Devil, Explores Steepest Slopes on Mars

A “beautiful dust devil” was just discovered today, April 1, on the Red Planet by NASA’s long lived Opportunity rover as she is simultaneously exploring water altered rock outcrops at the steepest slopes ever targeted during her 13 year long expedition across the Martian surface. Opportunity is searching for minerals formed in ancient flows of water that will provide critical insight into establishing whether life ever existed on the fourth rock from the sun.

“Yes a beautiful dust devil on the floor of Endeavour Crater,” Ray Arvidson, Opportunity Deputy Principal Investigator of Washington University in St. Louis, confirmed to Universe Today. Spied from where “Opportunity is located on the southwest part of Knudsen Ridge” in Marathon Valley.

The new dust devil – a mini tornado like feature – is seen scooting across the ever fascinating Martian landscape in our new photo mosaic illustrating the steep walled terrain inside Marathon Valley and overlooking the crater floor as Opportunity makes wheel tracks at the current worksite on a crest at Knudsen Ridge. The colorized navcam camera mosaic combines raw images taken today on Sol 4332 (1 April 2016) and stitched by the imaging team of Ken Kremer and Marco Di Lorenzo.

“The dust devils have been kind to this rover,” Jim Green, Director of NASA Planetary Sciences at NASA HQ, said in an exclusive interview with Universe Today. They are associated with prior periods of solar array cleansing power boosts that contributed decisively to her longevity.

“Oppy’s best friend is on its way!”

Spotting dust devils has been relatively rare for Opportunity since landing on Mars on Jan. 24, 2004.

“There are 7 candidates, 6 of which are likely or certain,” Mark Lemmon, rover science team member from Texas A & M University, told Universe Today. “Most were seen in, on the rim of, or adjacent to Endeavour.”

Starting in late January, scientists commanded the golf cart sized Opportunity to drive up the steepest slopes ever attempted by any Mars rover in order to reach rock outcrops where she can conduct breakthrough science investigations on smectite (phyllosilicate) clay mineral bearing rocks yielding clues to Mars watery past.

“We are beginning an imaging and contact science campaign in an area where CRISM spectra show evidence for deep absorptions associated with Fe [Iron], Mg [Magnesium] smectites,” Arvidson explained.

This is especially exciting to researchers because the phyllosilicate clay mineral rocks formed under water wet, non-acidic conditions that are more conducive to the formation of Martian life forms – billions of years ago when the planet was far warmer and wetter.

“We have been in the smectite [phyllosilicate clay mineral] zone for months, ever since we entered Marathon Valley.”

The smectites were discovered via extensive, specially targeted Mars orbital measurements gathered by the CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) spectrometer on NASA’s Mars Reconnaissance Orbiter (MRO) – accomplished earlier at the direction of Arvidson.

So the ancient, weathered slopes around Marathon Valley became a top priority science destination after they were found to hold a motherlode of ‘smectite’ clay minerals based on the CRISM data.

“Marathon Valley is unlike anything we have ever seen. Looks like a mining zone!”

At this moment, the rover is driving to an alternative rock outcrop located on the southwest area of the Knudsen Ridge hilltops after trying three times to get within reach of the clay minerals by extending her instrument laden robotic arm.

Unfortunately, but not unexpectedly, the rover kept slipping on the steep walled slopes – tilted as much as 32 degrees – while repeatedly attempting close approaches to the intended target. Ultimately she came within 3 inches of the surface science target ‘Pvt. Joseph Whitehouse’ – named after a member of the Corps of Discovery.

In fact despite rotating her wheels enough to push uphill about 66 feet (20 meters) if there had been no slippage, engineers discerned from telemetry that slippage was so great that “the vehicle progressed only about 3.5 inches (9 centimeters). This was the third attempt to reach the target and came up a few inches short,” said NASA.

“The rover team reached a tough decision to skip that target and move on.”

So they backed Opportunity downhill about 27 feet (8.2 meters), then drove about 200 feet (about 60 meters) generally southwestward and uphill, toward the next target area.

NASA officials noted that “the previous record for the steepest slope ever driven by any Mars rover was accomplished while Opportunity was approaching “Burns Cliff” about nine months after the mission’s January 2004 landing on Mars.”

Marathon Valley measures about 300 yards or meters long. It cuts downhill through the west rim of Endeavour crater from west to east – the same direction in which Opportunity is currently driving downhill from a mountain summit area atop the crater rim. See our route map below showing the context of the rovers over dozen year long traverse spanning more than the 26 mile distance of a Marathon runners race.

Endeavour crater spans some 22 kilometers (14 miles) in diameter. Opportunity has been exploring Endeavour since arriving at the humongous crater in 2011.

Why are the dust devils a big deal?

Offering more than just a pretty view, the dust devils actually have been associated with springtime Martian winds that clear away the dust obscuring the robots life giving solar panels.

“Opportunity is largely in winter mode sitting on a hill side getting maximum power. But it is in a better power status than in many past winters,” Jim Green, Director of NASA Planetary Sciences at NASA HQ, told Universe Today exclusively.

“I think I know the reason. As one looks across the vistas of Mars in this mosaic Oppys best friend is on its way.”

“The dust devils have been kind to this rover. Even I have a smile on my face when I see what’s coming.”

As of today, Sol 4332, Apr. 1, 2016, Opportunity has taken over 209,200 images and traversed over 26.53 miles (42.69 kilometers) – more than a marathon.

The power output from solar array energy production has climbed to 576 watt-hours, now just past the depths of southern hemisphere Martian winter.

Meanwhile Opportunity’s younger sister rover Curiosity traverses and drills into the basal layers at the base of Mount Sharp.
