Amazing, the things a birds-eye view allows you to see. Here’s a color image from the HiRISE camera on board the Mars Reconnaissance Orbiter showing the tracks of the Curiosity rover. In this most recent HiRISE image of the MSL rover, the tracks are visible from Yellowknife Bay to its location on 11 December 2013, several kilometers to the southwest. Even though some of these tracks are more than a year old, they are still visible.
As HiRISE team member Christian Schaller said via Twitter, “Take only pictures; leave only footprints.” In this case, HiRISE took the pictures while MSL left the footprints!
HiRISE principal investigator Alfred McEwen explained the image: “Curiosity is progressing from the bright dust-covered area to a region with a darker surface, where saltating sand keeps the surface relatively free of dust. The scenery seen by the rover will be getting more interesting as it progresses toward Mount Sharp.”

A Moment Frozen in Time On May 19th, 2005, NASA's Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera (Pancam) mosaic was taken around 6:07 in the evening of Sol 489. The terrain in the foreground is the rock outcrop "Jibsheet," a feature that Spirit has been investigating for several weeks (rover tracks are dimly visible leading up to "Jibsheet"). The floor of Gusev crater is visible in the distance, and the Sun is setting behind the wall of Gusev some 80 km (50 miles) in the distance. Credit: NASA/JPL-Caltech/Texas A&M/Cornell

But a decade ago, NASA’s six wheeled Spirit rover was but a promise of great things to come. And her rich Martian scientific heritage we know today was but a dream yet to ensue
Jan. 3 marks the 10th anniversary since her touchdown on Mars on Jan. 3, 2004. Her twin sister Opportunity soft landed 3 weeks later on Jan. 24, 2004.
So here’s a collection of some of Spirit’s greatest hits on the Red Planet for all to enjoy and remember her fabulous exploits.
Read my detailed new overview marking ‘Spirits 10 Years on Mars’ – here – with even more spectacular Red Planet imagery!

Since the golf cart sized Spirit snapped over 128,000 raw images, drove 4.8 miles and ground into 15 rock targets we can’t show everything.
Here’s a retrospective of some of our favorites.
In this selfie, Spirit shows her solar panels gleaming in the Martian sunlight and carrying only a thin veneer of dust two years after the rover landed and began exploring the red planet. Spirit’s panoramic camera took this mosaic of images on Sol 586 (Aug. 27, 2005), as part of a mammoth undertaking. The vertical projection used here produces the best view of the rover deck itself, though it distorts the ground and antennas somewhat. This image is an approximate true-color rendering that combines images taken through the camera’s 600-nanometer, 530-nanometer and 480-nanometer filters. Credit: NASA/JPL-Caltech/Cornell
During her more than six year lifetime spanning until March 2010, Spirit discovered compelling evidence that ancient Mars exhibited hydrothermal activity, hot springs and volcanic explosions flowing with water.
“Spirit’s big scientific accomplishments are the silica deposits at Home Plate, the carbonates at Comanche, and all the evidence for hydrothermal systems and explosive volcanism, Rover Principal Investigator Steve Squyres of Cornell University, explained to me in an earlier interview.
“What we’ve learned is that early Mars at Spirit’s site was a hot, violent place, with hot springs, steam vents, and volcanic explosions. It was extraordinarily different from the Mars of today.”
Meanwhile, NASA’s new Curiosity rover just celebrated 500 Sols on Mars and is speeding towards Mount Sharp from inside Gale Crater – which is about the same size as Gusev crater.
Stay tuned here for Ken’s continuing Mars rover, Curiosity, Chang’e-3, SpaceX, Orbital Sciences, LADEE, MAVEN, MOM and more news.

The images were acquired on Spirit’s sols 583 to 586 (Aug. 24 to 27, 2005), shortly after the rover reached the crest of “Husband Hill” inside Mars’ Gusev Crater. The panoramic camera shot 653 separate images in 6 different filters, encompassing the rover’s deck and the full 360 degrees of surface rocks and soils visible to the camera from this position. This was the first time the camera has been used to image the entire rover deck and visible surface from the same position.

Spirit collected data in late 2005 which confirmed that the Comanche outcrop contains magnesium iron carbonate, a mineral indicating the past environment was wet and non-acidic, possibly favorable to life. This view was captured during Sol 689 on Mars (Dec. 11, 2005). The find at Comanche is the first unambiguous evidence from either Spirit or Opportunity for a past Martian environment that may have been more favorable to life than the wet but acidic conditions indicated by the rovers’ earlier finds.

Today, Jan. 3, marks the 10th anniversary since the safe landing of NASA’s renowned Spirit rover on the plains of Mars on Jan. 3, 2004.
Spirit comprises one half of NASA’s now legendary pair of Mars Exploration Rovers (MER). Opportunity, her twin sister landed, on the opposite side of the Red Planet three weeks later – on Jan. 24, 2004. The goal was to “follow the water” as a potential enabler for past Martian microbes if they ever existed.
Together, the long-lived, golf cart sized robots proved that early Mars was warm and wet, billions of years ago – a key finding in the search for habitats conducive to life beyond Earth.
Exactly a decade ago, the famous robot survived the scorching atmospheric heating of the 6 minute plunge through the thin Martian atmosphere, bounced some two dozen times cocooned inside cushioning airbags, and gradually rolled to a stop inside 100 mile wide Gusev Crater. It was known as the “6 minutes of Terror”.
The three petaled landing pad opened and Spirit was dramatically born in a milestone event that will be forever remembered in the annuls of history because of the groundbreaking scientific discoveries that ensued and the unbelievable longevity of the twins.

Before they were launched atop Delta II rockets in the summer of 2003 from Cape Canaveral, the dynamic, solar powered robo duo were expected to last a mere three months – with a ‘warranty’ of 90 Martian days (Sols).
Either dust accumulation on the life giving solar panels, an engineering issue or the extremely harsh Martian environment was expected to somehow terminate them mercilessly.
In reality, both robots enormously exceeded expectations and accumulated a vast bonus time of exploration and discovery in numerous extended mission phases.
‘McMurdo’ Panorama from Spirit’s ‘Winter Haven’
This beautiful scene reveals a tremendous amount of detail in Spirit’s surroundings at a place called “Winter Haven,” where the rover spent many months parked on a north-facing slope in order to keep its solar panels pointed toward the sun for the winter. During this time, it captured several images to create this high resolution panorama. During that time, while the rover spent the daylight hours conducting as much scientific research as possible, science team members assigned informal names to rock outcrops, boulders, and patches of soil commemorating exploration sites in Antarctica and the southernmost islands of South America. Antarctic bases are places where researchers, like the rovers on Mars, hunker down for the winter in subzero temperatures. During the past Martian winter, Spirit endured temperatures lower than minus 100 degrees Celsius (minus 148 degrees Fahrenheit). Credit: NASA/JPL/Cornell
No one foresaw that Martian winds would occasionally clean the solar panels to give them a new lease on life or that the components would miraculously continue functioning.
Spirit endured the utterly extreme Red Planet climate for more than six years until communications ceased in 2010.
Opportunity is still roving Mars today, and doing so in rather good condition!
Altogether, Spirit drove 4.8 miles (7.73 kilometers),that’s about 12 times more than the original goal set for the mission.
She transmitted over 128,000 images.
After landing in the dusty plains, she headed for the nearby Columbia Hills some 2 miles away and ultimately became the first Martian mountaineer, when she scaled Husband Hill and found evidence for the flow of liquid water at the Hillary outcrop.
Spirit acquired this mosaic on Sol 1202 (May 21, 2007), while investigating the area east of the elevated plateau known as “Home Plate” in the “Columbia Hills.” The mosaic shows an area of disturbed soil, nicknamed “Gertrude Weise” by scientists, made by Spirit’s stuck right front wheel. The trench exposed a patch of nearly pure silica, with the composition of opal. It could have come from either a hot-spring environment or an environment called a fumarole, in which acidic, volcanic steam rises through cracks. Either way, its formation involved water, and on Earth, both of these types of settings teem with microbial life. Credit: NASA/JPL-Caltech/Cornell
The rovers were not designed to climb hills. But eventually she scaled 30 degree inclines.
The rover was equipped with a rock grinder named the Rock Abrasion Tool (RAT) built by Honeybee Robotics.
Spirit ground the surfaces off 15 rock targets and scoured 92 targets with a brush to prepare the targets for inspection with spectrometers and a microscopic imager, according to NASA.
Eventually she drove back down the hill and made even greater scientific discoveries in the area known as ‘Home Plate’.
Spirit survived three harsh Martian winters and only succumbed to the Antarctic-like temperatures when she unexpectedly became mired in an unseen sand trap driving beside an ancient volcanic feature named ‘Home Plate’ that prevented the solar arrays from generating life giving power to safeguard critical electronic and computer components.
In 2007, Spirit made one of the key discoveries of the mission at ‘Home Plate’ when her stuck right front wheel churned up a trench of bright Martian soil that exposed a patch of nearly pure silica, which was formed in a watery hot spring or volcanic environment.
Spirit was heading towards another pair of volcanic objects named ‘von Braun’ and ‘Goddard’ and came within just a few hundred feet when she died in the sand trap.

Here’s how the rovers’ principal investigator, Steve Squyres of Cornell University, Ithaca, N.Y., described some of the key findings in a NASA statement, starting with what Spirit found after driving from the crater floor where it landed into the Columbia hills to the east:
“In the Columbia Hills, we discovered compelling evidence of an ancient Mars that was a hot, wet, violent place, with volcanic explosions, hydrothermal activity, steam vents — nothing like Mars today.
“At Opportunity’s landing site, we found evidence of an early Mars that had acidic groundwater that sometimes reached the surface and evaporated away, leaving salts behind. It was an environment with liquid water, but very different from the environment that Spirit told us about.
“When Opportunity got to the rim of Endeavour Crater, we began a whole new mission. We found gypsum veins and a rich concentration of clay minerals. The clay minerals tell us about water chemistry that was neutral, instead of acidic — more favorable for microbial life, if any ever began on Mars.”
“Because of the rovers’ longevity, we essentially got four different landing sites for the price of two.”
Meanwhile, NASA’s new Curiosity rover just celebrated 500 Sols on Mars and is speeding towards Mount Sharp from inside Gale Crater – which is about the same size as Gusev crater.

Story updated[/caption]
Today, New Year’s Day 2014, NASA’s Curiosity mega rover celebrates a huge mission milestone – her 500th Martian Day on the Red Planet since the death defying touchdown of August 2012.
“500 Sols of Mars: While Earth celebrates #NewYear2014, midnight on Mars mark my 500th day of operations,” she tweeted today.
And Curiosity marked the grand occasion by snapping a fabulous new panorama spying towering Mount Sharp – looming dead ahead in her high resolution color cameras.
You can take in the magnificent Martian view Curiosity sees today – via our newly assembled mosaic of humongous Mount Sharp rising 5.5 kilometers (3.4 mi) into the Red Planets sky; see above and below.
Ascending mysterious Mount Sharp – which dominates the Gale Crater landing site – is the ultimate reason for Curiosity’s being.

NASA’s science and engineering teams dispatched the state-of-the-art robot there because they believe the lower sedimentary layers hold the clues to the time period when Mars was habitable eons ago and they possess the required chemical ingredients necessary to sustain microbial life.
But first she needs to reach the mountains foothills.
So, just like some Earthlings, Curiosity also set a New Year’s resolution she’d like to share with you all – just tweeted all the way from the Red Planet.
“Goals for 2014: Finish driving to Mars’ Mount Sharp & do all the science I can.”

Part of those goals involve shifting the missions focus to include the search for organic molecules – the building blocks of life as we know it – which may be preserved in the sedimentary rock layers.
“Really what we’re doing is turning the corner from a mission that is dedicated to the search for habitable environments to a mission that is now dedicated to the search for that subset of habitable environments which also preserves organic carbon,” Curiosity Principal Investigator John Grotzinger, of the California Institute of Technology in Pasadena, said recently at the Dec. 2013 annual meeting of the American Geophysical Union (AGU).
The 1 ton behemoth is in the midst of an epic trek to destination Mount Sharp, roving across 10 kilometers (6 mi.) of the rather rocky crater floor of her landing site inside Gale Crater.

But the alien crater floor strewn with a plethora of sharp edged rocks is ripping significant sized holes and causing numerous dents in several of the rovers six big aluminum wheels – as outlined in my prior report; here.

“Routes to future destinations for the mission may be charted to lessen the amount of travel over such rough terrain, compared to smoother ground nearby,” says NASA.
So far Curiosity’s odometer stands at 4.6 kilometers, following a post Christmas drive on Dec. 26, 2013 (Sol 494) after 16 months roving the Red Planet.
Curiosity’s handlers will be diligently watching the wear and tear on the 20 inch diameter wheels. She needs to rove along a smoother path forward to minimize wheel damage by sharp rocks.
Here’s our latest wheel mosaic from Dec. 26, 2013 (Sol 494) showing a several centimeter wide puncture in the left front wheel, which seems to have suffered the most damage.
The Mount Sharp and wheel mosaics were assembled by the imaging team of Marco Di Lorenzo and Ken Kremer.

“Taking stock this holiday season. I’m planning smoother paths for the new year,” Curiosity tweeted.
The team hopes the intrepid robot arrives at the base of Mount Sharp around the middle of this new year 2014, if all goes well.
Shortly thereafter the robot begins a new phase with the dramatic ascent up the chosen entryway which the team dubs the ‘Murray Buttes’ – fittingly named in honor of Bruce Murray, a Caltech planetary geologist, who worked on science teams of NASA’s earliest missions to Mars in the 1960s and ’70s.

Murray also was the director of NASA’s Jet Propulsion Laboratory from 1976 to 1982 and co-founded the Planetary Society in 1980. He passed away on Aug. 29, 2013.
“Bruce Murray contributed both scientific insight and leadership that laid the groundwork for interplanetary missions such as robotic missions to Mars, including the Mars rovers, part of America’s inspirational accomplishments. It is fitting that the rover teams have chosen his name for significant landmarks on their expeditions,” said NASA Mars Exploration Program Manager Fuk Li, of NASA’s Jet Propulsion Laboratory (JPL) , Pasadena, Calif.
Curiosity has already accomplished her primary goal of discovering a habitable zone on Mars that could support Martian microbes if they ever existed.
NASA’s rover Curiosity uncovered evidence that an ancient Martian lake had the right chemical ingredients, including clay minerals that could have sustained microbial life forms for long periods of time – and that these habitable conditions persisted on the Red Planet until a more recent epoch than previously thought.

Several of the NASA rovers six big aluminum wheels have suffered some significant sized rips, tears and holes up to several centimeters wide – in addition to numerous dents – as she has picked up the driving pace across the rugged, rock filled Martian terrain this past fall and put over 4.5 kilometers (3 mi.) on the odometer to date.
It’s rather easy to spot the wheel damage to the 1 ton behemoth by examining the mosaic imagery we have created – See above and below – from newly transmitted raw imagery and comparing that to older imagery taken at earlier points in the mission. Check our Sol 177 wheels mosaic below.
The latest imagery from Mars captured just prior to Christmas is delivering an undesired holiday present of sorts to team members that might well cause the scientists and engineers to alter Curiosity’s extraterrestrial road trip to traverse smoother terrain and thereby minimize future harm.
So the wheel damage is certainly manageable at this point but will require attention.
The team of Marco Di Lorenzo and Ken Kremer have assembled the new Mastcam and MAHLI raw images of the wheels captured on Sol 490 (Dec. 22) into fresh color mosaics – shown herein.

Indeed the rovers handlers have already directed the SUV sized Curiosity to snap close up images of the 20 inch diameter wheels with the high resolution color cameras located on the Mast as well as the Mars Hand Lens Imager (MAHLI) camera at the end of the rover’s maneuverable robotic arm.
“We want to take a full inventory of the condition of the wheels,” said Jim Erickson of NASA’s Jet Propulsion Laboratory, project manager for the NASA Mars Science Laboratory Project, in a NASA statement.

The rover team certainly expected some wear and tear to accumulate along the rock strewn path to the base of Mount Sharp – which reaches 5.5 km (3.4 mi) into the Martian sky.
But the volume of sharp edged rocks encountered in the momentous trek across the floor of Curiosity’s Gale Crater landing site apparently has picked up- as evidenced by the new pictures – and consequently caused more damage than the engineers anticipated.
“Dents and holes were anticipated, but the amount of wear appears to have accelerated in the past month or so,” Erickson noted.
“It appears to be correlated with driving over rougher terrain. The wheels can sustain significant damage without impairing the rover’s ability to drive. However, we would like to understand the impact that this terrain type has on the wheels, to help with planning future drives.”
The team is now inspecting the new imagery acquired of the wheels and will decide if a course alteration to Mount Sharp is in order.
The left front wheel may have suffered the most harm.

NASA’s Curiosity rover has discovered evidence that an ancient Martian lake had the right chemical ingredients that could have sustained microbial life forms for long periods of time – and that these habitable conditions persisted on the Red Planet until a more recent epoch than previously thought.
Furthermore researchers have developed a novel technique allowing Curiosity to accurately date Martian rocks for the first time ever – rather than having to rely on educated guesses based on counting craters.
All that and more stems from science results just announced by members of the rover science team.
Researchers outlined their remarkable findings in a series of six new scientific papers published today (Dec. 9) in the highly respected journal Science and at talks held today at the Fall 2013 Annual Meeting of the American Geophysical Union (AGU) in San Francisco.
The Curiosity team also revealed that an investigation of natural Martian erosion processes could be used to direct the rover to spots with a higher likelihood of holding preserved evidence for the building blocks of past life – if it ever existed.
View of Yellowknife Bay Formation, with Drilling Sites

The ancient fresh water lake at the Yellowknife Bay area inside the Gale Crater landing site explored earlier this year by Curiosity existed for periods spanning perhaps millions to tens of millions of years in length – before eventually evaporating completely after Mars lost its thick atmosphere.
Furthermore the lake may have existed until as recently as 3.7 Billion years ago, much later than researchers expected which means that life had a longer and better chance of gaining a foothold on the Red Planet before it was transformed into its current cold, arid state.

Researchers also announced that they are shifting the missions focus from searching for habitable environments to searching for organic molecules – the building blocks of all life as we know it.
Why the shift? Because the team believes they have found a way to increase the chance of finding organics preserved in the sedimentary rock layers.
“Really what we’re doing is turning the corner from a mission that is dedicated to the search for habitable environments to a mission that is now dedicated to the search for that subset of habitable environments which also preserves organic carbon,” Curiosity Principal Investigator John Grotzinger, of the California Institute of Technology in Pasadena, said at an AGU press conference today.
“That’s the step we need to take as we explore for evidence of life on Mars.”
Earlier this year, Curiosity drilled into a pair of sedimentary Martian mudstone rock outcrops at Yellowknife Bay known as “John Klein” and “Cumberland” – for the first time in history.
Grotzinger said the ancient lake at Yellowknife Bay was likely about 30 miles long and 3 miles wide.
Powdered samples deposited into the rovers miniaturized chemistry labs – SAM and CheMin – revealed the presence of significant levels of phyllosilicate clay minerals.
These clay minerals form in neutral pH water that is ‘drinkable” and conducive to the formation of life.
“Curiosity discovered that the fine-grained sedimentary rocks preserve evidence of an environment that would have been suited to support a Martian biosphere founded on chemolithoautotrophy,” according to one of the science papers co-authored by Grotzinger.
“This aqueous environment was characterized by neutral pH, low salinity, and variable redox states of both iron and sulfur species.”
The rover has detected key elements required for life including carbon, hydrogen, oxygen, sulfur nitrogen and phosphorous.
The team is still looking for signatures of organic molecules.
Right now the researchers are driving Curiosity along a 6 mile path to the base of Mount Sharp -the primary mission destination – which they hope to reach sometime in Spring 2014.
But along the way they hope to stop at a spot where wind has eroded the sedimentary rocks just recently enough to expose an area that may still preserve evidence for organic molecules – since it hasn’t been bombarded by destructive cosmic radiation for billions of years.
Stay tuned here for Ken’s continuing Curiosity, Chang’e 3, LADEE, MAVEN and MOM news.

Indian space engineers initiated the 440 Newton liquid fueled engine firing precisely as planned at 00:49 hrs (IST) on Sunday, Dec. 1, 2013 during a critical nail-biting burn lasting some 22 minutes.
The Trans Mars Insertion (TMI) firing propelled India’s Mars Orbiter Mission (MOM) away from Earth forever and placed the spacecraft on course for a rendezvous with the Red Planet on September 24, 2014 – where it will study the atmosphere and sniff for signals of methane.
Sunday’s Mars insertion burn imparted the vehicle with an incremental velocity of 647.96 meters per second (m/sec) consuming 198 kg of fuel.
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
The maneuver dubbed ‘The mother of all slingshots’, enabled MOM to finally achieve escape velocity and catapulted the 1,350 kilogram (2,980 pound) spacecraft on an historic flight streaking towards Mars.
And in a rare but rather delightful coincidence, MOM is not alone on her remarkable Martian sojourn. Following the triumphant engine burn, she now joins NASA’s MAVEN orbiter in a gallant marathon race to the Red Planet.
MOM was designed and developed by the Indian Space Research Organization’s (ISRO) at a cost of $69 Million and marks India’s inaugural foray into interplanetary flight.
“The Earth orbiting phase of the spacecraft ended,” with this maneuver said ISRO.
MOM is healthy and all systems are functioning normally.
While MOM was cycling Earth, ISRO scientists and engineers activated and tested the probes systems and science payloads.

MOM is nicknamed ‘Mangalyaan’ – which in Hindi means ‘Mars craft.’
MOM’s journey bagen with a picture perfect Nov. 5 liftoff atop India’s highly reliable four stage Polar Satellite Launch Vehicle (PSLV) C25 from ISRO’s Satish Dhawan Space Centre SHAR, Sriharikota.
The PSLV booster precisely injected MOM into an initial elliptical Earth parking orbit of 247 x 23556 kilometers with an inclination of 19.2 degrees.
PSLV does not have sufficient thrust to send MOM streaking directly to the Red Planet.
Therefore since the flawless launch, the engine has been fired 6 times on November 7, 8, 9, 11, and 16 plus one supplementary maneuver to gradually raise the spacecrafts apogee from 23556 km to 192,874 km.
The most recent orbit raising maneuver occurred on Nov 16, 2013 with a burn time of 243.5 seconds and increased the apogee from 118,642 km to 192,874 km.

Today’s burn was the final one around Earth and absolutely crucial for setting her on course for Mars.
MOM was the first of two missions dispatched to Mars by Earthlings this November.
Half a world away, NASA’s MAVEN orbiter blasted off on Nov. 18 from Cape Canaveral Air Force Station, Florida atop an Atlas V booster on a direct path to the Red Planet.
The MOM spacecraft is now on traveling on a heliocentric elliptical trajectory to begin a 300 day long interplanetary voyage of more than 700 Million kilometers (400 Million miles) to the Red Planet.
Along the path to Mars, ISRO plans to conduct a series of Trajectory Correction Maneuvers (TCMs) using MOM’s Attitude and Orbit Control System (AOCS) thrusters to precisely navigate the probe to the point required to achieve orbit around the Red Planet
Following the ten month cruise through space the orbital insertion engine will fire for a do or die burn on September 24, 2014 placing MOM into an 377 km x 80,000 km elliptical orbit around Mars.
MOM will reach Mars vicinity just two days after MAVEN’s arrival on Sept. 22, 2014.
If all continues to 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.
Although MOM’s main objective is a demonstration of technological capabilities, the probe is equipped with five indigenous instruments to conduct meaningful science – including a multi color imager and a methane gas sniffer to study the Red Planet’s atmosphere, morphology, mineralogy and surface features. Methane on Earth originates from both geological and biological sources – and could be a potential marker for the existence of Martian microbes.
MOM’s 15 kg (33 lb) science suite comprises:
MCM: the tri color Mars Color Camera images the planet and its two tiny moons, Phobos and Deimos
LAP: the Lyman Alpha Photometer measures the abundance of hydrogen and deuterium to understand the planets water loss process
TIS: the Thermal Imaging Spectrometer will map surface composition and mineralogy
MENCA: the Mars Exospheric Neutral Composition Analyser is a quadrapole mass spectrometer to analyze atmospheric composition
MSM: the Methane Sensor for Mars measures traces of potential atmospheric methane down to the ppm level.
Scientists will be paying close attention to whether MOM detects any atmospheric methane to compare with measurements from NASA’s Curiosity rover – which found ground level methane to be essentially nonexistent – and Europe’s upcoming 2016 ExoMars Trace Gas Orbiter.
India’s MOM – ‘Mangalyaan’ mission is expected to continue gathering measurements at the Red Planet for at least six months and hopefully much longer.
MAVEN could operate for a decade or longer and is also crucial for relaying images and data collected by NASA’s current and upcoming surface rovers and landers.
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.

The clock is ticking down relentlessly towards “The mother of all slingshots” – the critical engine firing intended to hurl India’ Mars Orbiter Mission (MOM) probe on her ten month long interplanetary cruise to the Red Planet.
Engineers at the Indian Space Research Organization’s (ISRO) Mission Operations Complex at Bangalore are now just hours away from sending the commands that will ignite MOMs’ liquid fueled main engine for TMI – the Trans Mars Insertion maneuver that will propel MOM away from Earth forever and place the craft on an elliptical trajectory to the Red Planet.
“Performance assessment of all subsystems of the spacecraft has been completed,” reports ISRO.
The do or die 1351 second burn is slated to begin at 00:49 hrs IST tonight – on Dec. 1 Indian local time.

The most recent orbit raising maneuver occurred at 01:27 hrs (IST) on Nov 16, 2013 with a burn time of 243.5 seconds increased the apogee from 118,642 km to 192,874 km.
Tonight burn is MOM’s final one around Earth and absolutely crucial for setting her on course for Mars.
If all goes well the $69 million MOM spacecraft reaches the vicinity of Mars on 24 September 2014.
MOM was the first of two Earth missions to Mars launched this November.
NASA’s $671 Million MAVEN orbiter launched as scheduled on Nov. 18, from Cape Canaveral, Florida and arrives at Mars on Sept. 22, 2014, about two days before MOM.
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.

CAPE CANAVERAL, FL – NASA’s car sized CuriosityMars rover has resumed full science operations and driving following a six day long halt to research activities due to concerns about an electrical power system glitch, which have now been resolved.
On Nov. 17, engineers noticed a fluctuation in voltage on Curiosity that caused the robots handlers to stop science activities and driving towards mysterious Mount Sharp while they searched for the root cause of the electrical issue.
NASA says that the voltage change did not impact the rovers safety or health and the team was acting out of an abundance of caution while investigating the situation from millions of miles away back on Earth.
“The vehicle’s electrical system has a “floating bus” design feature to tolerate a range of voltage differences between the vehicle’s chassis — its mechanical frame — and the 32-volt power lines that deliver electricity throughout the rover. This protects the rover from electrical shorts,” NASA said in a statement.
Curiosity’s voltage level had been about 11 volts since landing day and had declined to about 4 volts on Nov. 17. The electrical issue did not trigger the rover to enter a safe-mode status.

Engineers amassed a list of possible causes for the voltage change while suspending science operations and roving across the Martian crater floor where Curiosity landed nearly a year and a half ago in August 2012.
“We made a list of potential causes, and then determined which we could cross off the list, one by one,” said rover electrical engineer Rob Zimmerman of NASA’s Jet Propulsion Laboratory, Pasadena, Calif.
NASA says that the likely cause is an internal short stemming from the Radioisotope Thermoelectric Generator (RTG) – the rovers nuclear power source.
RTG’s have been commonly used on many NASA missions that also experienced occasional shorts and that had no long term impact or loss of capability on their flights.
“This type of intermittent short has been seen in similar RTGs, including the one on the Cassini spacecraft, which has been orbiting Saturn for years. The rover electronics are designed to operate at variable power supply voltages, so this is not a major problem,” says Curiosity team member Ken Herkenhoff of the USGS in a mission update.
The voltage level had returned its normal level of 11 volts on its own by Nov. 23, when the team had decided to resume science operations.
So it is possible that the same type of intermittent voltage change could recur in the future.
Meanwhile the rover has resumed her epic trek to Mount Sharp and is expected to arrive at the base of the mountain sometime in mid-2014.

This past weekend, the robot delivered additional portions of powdered rock to the CheMin and SAM labs inside the rover. The sample was collected 6 months ago after drilling into a rock nicknamed “Cumberland” and will supplement prior measurements.
Curiosity has already accomplished her primary science goal of discovering a habitable zone at her landing site.
Scientists expect to broaden the region of Martian habitability once the 1 ton robot begins the ascent of Mount Sharp to investigate the sedimentary layers in the lower reaches of the towering 3 mile (5 km) high mountain, that record Mars geologic and climatic history over a time span of billions of years.

And as both of NASA’s rovers Curiosity and Opportunity ascend Martian mountains, they’ll be joined next September 2014 by a pair of new Martian orbiters from the US and India – MAVEN and MOM – that will significantly expand Earth’s invasion force at the Red Planet.

CAPE CANAVERAL, FL – MOM is looking at you, kid!
And if the spectacular new image of billions of Earth’s children captured by India’s Mars Orbiter Mission (MOM) is any indication (see above), then we can expect absolutely gorgeous scenes of the Red Planet once the groundbreaking probe arrives there in September 2014.
But despite all that’s been accomplished so far, the space drama is still in its infant stages – because MOM still needs to ignite her thrusters this weekend in order to achieve escape velocity, wave good bye to Earth forever and eventually say hello to Mars!
The picture – snapped from Earth orbit – is focused on the Indian subcontinent, the probes origin.
MOM has captured the imagination of space enthusiasts worldwide.
During testing of the MOM probes payloads – while it’s still flying in a highly elliptical orbit around our Home Planet – engineers from India’s space agency turned the crafts camera homewards to capture the “First ever image of Earth Taken by Mars Color Camera,” according to the Indian Space Research Organization (ISRO).
The beautiful image was taken on Nov. 20 at around 1350 hrs (IST) from a height of almost 70,000 km above earth and has a spatial resolution of 3.5 km, said ISRO.
The image also gives a rather good approximation of what MOM’s color camera will actually see from apoapsis after reaching the Red Planet since the probe will enter a similarly highly elliptical orbit around Mars – ranging in altitude from 366 kilometers (km) x 80,000 kilometers (km).

Following a 10 month interplanetary cruise, MOM is due to arrive in the vicinity of Mars on September 24, 2014 to study the Red Planets’ atmosphere.
At that time, the 440 Newton liquid fueled main engine must fire precisely as planned during the absolutely essential Mars orbital insertion burn to place the probe into orbit about Mars.
But before MOM can accomplish anything at Mars, she must first successfully fire her main engine – to complete the crucial departure from Earth and Trans Mars Insertion (TMI) scheduled for this Saturday!
MOM’s picture perfect Nov. 5 liftoff atop India’s highly reliable four stage Polar Satellite Launch Vehicle (PSLV) C25 from the ISRO’s Satish Dhawan Space Centre SHAR, Sriharikota, precisely injected the spacecraft into an initial elliptical Earth parking orbit of 247 x 23556 kilometers with an inclination of 19.2 degrees.
Since then the engine has fired 6 times to gradually raise the spacecrafts apogee.
The most recent orbit raising maneuver occurred at 01:27 hrs (IST) on Nov 16, 2013 with a burn time of 243.5 seconds increased the apogee from 118,642 km to 192,874 km.
The nail-biting final main engine burn of 1351 seconds is set for this weekend on Dec. 1. It will place MOM on a precise interplanetary trajectory to the Red Planet.
