India’s historic first mission to Mars is now celebrating one year orbiting the Red Planet and may continue working for years to come. During year one the spacecraft was highly productive, achieving its goals of taking hordes of breathtaking images and gathering scientific measurements to study Mars atmosphere, surface environments, morphology, and mineralogy.

The Mars Orbiter Mission, or MOM, is India’s first deep space voyager to explore beyond the confines of her home planets influence and successfully arrived at the Red Planet after the “history creating” orbital insertion maneuver on Sept. 23/24, 2014 following a ten month interplanetary journey from Earth.

The MOM orbiter was designed and developed by the Indian Space Research Organization (ISRO), India’s space agency, which is the equivalent of NASA.

“Mars Orbiter spacecraft marks one year of its life around the Red Planet today [Sept. 24, IST],” said ISRO. It was primarily designed as a technology demonstrator but is also outfitted with significant science instruments.

The probe is equipped with a 15 kg (33 lb) suite of five indigenous instruments to conduct meaningful science – including the tri color Mars Color Camera imager (MCC) and a methane gas sniffer (MSM) 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.

“After successfully completing one year of the mission life around Mars, now a large data set has been acquired by all five payloads of MOM,” ISRO stated.

To mark the one year anniversary ISRO released a new 120 page “Mars Atlas” of imagery and results, which can be downloaded from the ISRO website.

“The images from MCC have provided unique information about Mars at varying spatial resolutions. It has obtained Mars Global data showing clouds, dust in atmosphere and surface albedo variations, when acquired from apoapsis at around 72000 km.”

“On the other hand high resolution images acquired from periapsis show details of various morphological features on the surface of Mars. Some of these images have been showcased in this atlas. The images have been categorized depending upon the Martian surface and atmospheric processes.”

MOM was built in record time and for a budget of $73 million.

“The MOM spacecraft was designed, built and launched in record period of less than two years,” ISRO explained. “MOM carried five science instruments collecting data on surface geology, morphology, atmospheric processes, surface temperature and atmospheric escape process.”

MOM’s Martian arrival was webcast worldwide with an elaborate ceremony that included India’s prime minister who beamed with pride in the team and the nation at that time.

“India has successfully reached Mars!” declared Indian prime minister Narendra Modi, who watched the events unfold from mission control at ISRO’s Telemetry, Tracking and Command Network (ISTRAC) in Bangalore, on Sept. 24, 2014.

“History has been created today. We have dared to reach out into the unknown and have achieved the near-impossible. I congratulate all ISRO scientists as well as all my fellow Indians on this historic occasion.”

MOM swoops around the Red Planet in a highly elliptical orbit whose nearest point to Mars (periapsis) is about 421.7 km and farthest point (apoapsis) is about 76,993.6 km, according to ISRO

Upon MOM’s arrival, India became the newest member of an elite club of only four entities who have launched probes that successfully investigated Mars – following the Soviet Union, the United States and the European Space Agency (ESA).

MOM was launched 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.

The Indian probe arrived just two days after NASA’s MAVEN Mars orbiter, the first mission specifically targeted to study Mars tenuous upper atmosphere and the escape rates of atmospheric constituents.

The $73 million MOM mission was initially expected to last at least six months. In March 2015, ISRO extended the mission duration for another six months since its healthy, the five science instruments were operating fine and it had sufficient fuel reserves.

Indeed MOM has enough fuel to continue gather data and images for years to come if the instruments and spacecraft continue to function nominally.

“The Mars Orbiter Mission still has some 45 kg of fuel left which could, in theory, keep the mission going for at least 15 years,” ISRO told The Hindu.

“One cannot get a better bang for the buck! According to ISRO, for normal housekeeping operations and orbit maintenance only about two kg of fuel is necessary per year.”

Including MOM, Earth’s invasion fleet at the Red Planet numbers a total of seven spacecraft comprising five orbiters from NASA, ESA and ISRO as well as the sister pair of mobile surface rovers from NASA – Curiosity and Opportunity.

Curiosity Snaps Stunning One of a Kind Belly Selfie At Buckskin Mountain Base Drill Site

This low-angle self-portrait of NASA’s Curiosity Mars rover shows the vehicle at the site from which it reached down to drill into a rock target called “Buckskin.” The MAHLI camera on Curiosity’s robotic arm took multiple images on Aug. 5, 2015, that were stitched together into this selfie.

More selfie and drilling mosaics below[/caption]

NASA’s Curiosity rover has snapped a stunningly beautiful, one of a kind ‘belly selfie’ amidst the painstaking ‘Buckskin’ drill campaign at the Martian mountain base marking the third anniversary since her touchdown on the Red Planet.

The unique self portrait was taken from a low-angle for the first time and shows the six wheeled rover at work collecting her seventh drilled sample at the ‘Buckskin’ rock target earlier this month in the “Marias Pass” area of lower Mount Sharp.

‘Buckskin’ is also unique in a fabulously scientifically way because the rover discovered a new type of Martian rock that’s surprisingly rich in silica – and unlike any other targets found before.

The low camera angle is what enables the awesome Buckskin belly selfie. It’s a distinctively dramatic view and actually stitched from 92 images captured by the Mars Hand Lens Imager (MAHLI) on Aug. 5, 2015, or Sol 1065 of the mission.

The high resolution MAHLI color camera is located on the end of the 7 foot-long (2.1 meter-long) robotic arm.

This version of a self-portrait of NASA's Curiosity Mars rover at a drilling site called "Buckskin" is presented as a stereographic projection, which shows the horizon as a circle. The MAHLI camera on Curiosity's robotic arm took dozens of component images for this selfie on Aug. 5, 2015.

Indeed the car-sized rover has taken spectacular selfies several times before during her three year long trek across the Martian surface, since the August 2012 landing inside Mars’ Gale Crater. But for those past selfies the MAHLI camera was hoisted higher to give the perspective of looking somewhat downward and showing the rovers top deck and trio of sample inlet ports.

In this case, the rover team specifically commanded Curiosity to position “the camera lower in relation to the rover body than for any previous full self-portrait of Curiosity,” said NASA officials.

Two patches of gray colored powdered rock material drilled from Buckskin are visible in the selfie scene, in front of the rover.

“The patch closer to the rover is where the sample-handling mechanism on Curiosity’s robotic arm dumped collected material that did not pass through a sieve in the mechanism. Sieved sample material was delivered to laboratory instruments inside the rover. The patch farther in front of the rover, roughly triangular in shape, shows where fresh tailings spread downhill from the drilling process.”

Prior selfies were taken at the “Rocknest” (http://photojournal.jpl.nasa.gov/catalog/PIA16468), “John Klein” (http://photojournal.jpl.nasa.gov/catalog/PIA16937), “Windjana” (http://photojournal.jpl.nasa.gov/catalog/PIA18390) and “Mojave” drill sites.

Basically in the Sol 1065 belly selfie at “Buckskin” we see the underbelly of the rover and all six wheels along with a complete self portrait.

On several prior occasions, MAHLI was used to image just the underbelly and wheels to aid in inspecting the wheels to look for signs of damage inflicted by sharp-edged Martian rocks poking holes in the aluminum wheels.

Each wheel measures 20 inches (50 centimeters) in diameter and about 16 inches (40 centimeters) wide. And the MAHLI monitoring images have shown the effects of increasing wear and tear that ultimately forced the rover drivers to alter Curiosity’s driving route on the crater floor in favor of smoother and less rocky terrain imparting less damage to the critical wheels.

If you take a close look at the new selfie up top, you’ll see a small rock stuck onto Curiosity’s left middle wheel (on the right in this head-on view). The rock was seen also in prior wheel monitoring images taken three weeks ago.

“The selfie at Buckskin does not include the rover’s robotic arm beyond a portion of the upper arm held nearly vertical from the shoulder joint. With the wrist motions and turret rotations used in pointing the camera for the component images, the arm was positioned out of the shot in the frames or portions of frames used in this mosaic,” according to officials.

The drilling campaign into “Buckskin” was successfully conducted on Sol 1060 (July 30, 2015) at the bright toned “Lion” outcrop to a full depth of about 2.6 inches (6.5 centimeters) and approximately 1.6 cm (0.63 inch) diameter.

Curiosity has now moved on from the “Marias Pass” area.

Curiosity recently celebrated 1000 Sols of exploration on Mars on May 31, 2015 – detailed here with our Sol 1000 mosaic also featured at Astronomy Picture of the Day on June 13, 2015.

As of today, Sol 1080, August 20, 2015, she has driven some 6.9 miles (11.1 kilometers) kilometers and taken over 260,000 amazing images.

Curiosity has already accomplished her primary objective of discovering a habitable zone on the Red Planet – at the Yellowknife Bay area – that contains the minerals necessary to support microbial life in the ancient past when Mars was far wetter and warmer billions of years ago.

Indian Mars Orbiter Shoots Spectacular New Images of Sheer Canyon and Curiosity’s Crater

India’s space agency has released a spectacular new batch of images taken by everyone’s favorite MOM – the Mars Orbiter Mission – the nation’s first probe ever dispatched to the Red Planet and which achieved orbit nearly a year ago.

The Indian Space Research Organization (ISRO) has published a beautiful gallery of images featuring a steep and stunning Martian canyon and the landing site of NASA’s Curiosity Mars Science Laboratory rover, and more.

The lead image was taken over the Ophir Chasma canyon on the Martian surface by the Mars Colour Camera aboard India’s Mars Orbiter Mission.

Ophir Chasma is a canyon in the Coprates quadrangle located at 4° south latitude and 72.5° west longitude. It is part of the Valles Marineris – the ‘Grand Canyon of Mars’ – and the largest known canyon in the Solar System.

The image was captured on July 19, 2015 from an altitude of 1857 kilometers (1154 miles). It has with a resolution of 96 meters.

The steep walled Ophir Chasma canyon contains many layers and the floors contain large deposits of layered materials, perhaps even sulfates.

Ophir Chasma is about 317 kilometers long and about 8 to 10 kilometers deep located near the center of Valles Marineris – see map below.

Valles Marineris stretches over 4,000 km (2,500 mi) across the Red Planet, is as much as 600 km wide and measures as much as 10 kilometers (6 mi) deep. It is nearly as wide as the United States.

Here’s an illuminating and magnificent 3D portrayal of Ophir Chasma created by Indian scientists that gives a sense of the canyons scale, sheer walls and cliffs and depth:

The newest images were snapped after the spacecraft exited the communications blackout encountered by all of Earth’s invasion fleet of Red Planet orbiters and rovers during the recent conjunction period when Mars was behind the sun during much of June.

See the prior image release from ISRO in my MOM story – here.

Here’s a wider view of Valles Marineris showing Ophir Chasma in a previously published MOM image from ISRO.

ISRO also released a delightful new image of Gale Crater and the surrounding vicinity.

Gale Crater is the landing site of NASA’s Curiosity rover. MOM took the image from an altitude of 9004 kilometers.

Gale Crater is home to humongous Mount Sharp, a mountain that rises 5.5 kilometers (3.4 miles) from the crater floor and is easily visible in the photo from MOM. The crater is 154 kilometers (96 mi) wide.

Curiosity is currently exploring the foothills of Mount Sharp around the top of the image – which shows a rather different perspective from what we’ve seen from prior familiar orbital imagery snapped by several NASA and ESA orbiters.

The 1 ton rover recently celebrated the 3rd anniversary since its nailbiting touchdown inside Gale crater. And the new wider angle image from MOM gives a fabulous sense of exactly why a highly precise landing was essential – otherwise it would have been doomed.

Curiosity recently drilled into the “Buckskin” target at an outcrop at the foothills of Mount Sharp. See the mountain in our ground level mosaic from the crater floor. And its kind of neat to actually imagine Curiosity sitting there while perusing MOM’s photo.

MOM’s goal is to study Mars atmosphere, surface environments, morphology, and mineralogy with a 15 kg (33 lb) suite of five indigenously built science instruments. It is also sniffing for methane, a potential marker for biological activity.

The Indian probe arrived just after NASA’s MAVEN Mars orbiter, the first mission specifically targeted to study Mars tenuous upper atmosphere and the escape rates of atmospheric constituents.

MOM swoops around Mars in a highly elliptical orbit whose nearest point to the planet (periapsis) is at about 421 km and farthest point (apoapsis) at about 76,000 km, according to ISRO.

It takes MOM about 3.2 Earth days or 72 hours to orbit the Red Planet.

The $73 million MOM mission was expected to last at least six months. In March, ISRO extended the mission duration for another six months since its healthy, the five science instruments are operating fine and it has sufficient fuel reserves.

Dazzling Gallery From India’s MOM Mars Orbiter Camera

Story updated with more details and imagery[/caption]

India’s first ever robotic explorer to the Red Planet, the Mars Orbiter Mission, more affectionately known as MOM, has captured an absolutely dazzling array of images of the fourth rock from the Sun.

The Indian Space Research Organization (ISRO), India’s space agency, has recently published a beautiful gallery of images featuring a variety of picturesque Martian canyons, volcanoes, craters, moons and more.

We’ve gathered a collection here of MOM’s newest imagery snapped by the probes Mars Color Camera (MCC) for the enjoyment of Martian fans worldwide.

The spectacular 3D view of the Arsia Mons volcano, shown above, was “created by draping the MCC image on topography of the region derived from the Mars Orbiter Laser Altimeter (MOLA), one of five instruments on board NASA’s Mars Global Surveyor (MGS) spacecraft.

The Arsia Mons image was taken from Mars orbit on 1 April 2015 at a spatial resolution of 556 meters from an altitude of 10707 km. Volcanic deposits can be seen located at the flanks of the Mons, according to ISRO.

The view of Pital crater below was released in late May and taken on 23 April 2015. Pital is a 40 km wide impact crater located in the Ophir Planum region of Mars and the image shows a chain of small impact craters. It is located in the eastern part of Valles Marineris region, says an ISRO description. MCC took the image from an altitude of 808 km.

It is an odd shaped crater, neither circular nor elliptical in shape, possibly due to “regional fracture in the W-E trending fracture zone.”

A trio of images, including one in stunning 3D, shows various portions of Valles Marineris, the largest known canyon in the Solar System.

Valles Marineris stretches over 4,000 km (2,500 mi) across the Red Planet , is as much as 600 km wide and measures as much as 7 kilometers (4 mi) deep.

For context here’s a previously taken global image of the red planet from MOM showing Valles Marinaris and Arsia Mons, which belongs to the Tharsis Bulge trio of shield volcanoes. They are both near the Martian equator.

Valles Marineris is often called the “Grand Canyon of Mars.” It spans about as wide as the entire United States.

And with a communications blackout between Mars and Earth imminent as a result of natures solar conjunction, it’s the perfect time to catch up on all things Martian.

Solar conjunctions occur periodically between Mars and Earth about every 26 months, when the two planets line up basically in a straight line geometry with the sun in between as the two planets travel in their sun-centered orbits.

Since Mars will be located behind the Sun for most of June, communications with all the Terran spacecraft at the planet is diminished to nonexistent.

“MOM faces a communication outage during June 8-25,” according to The Hindu.

Normal science operations resume thereafter.

“Fuel on the spacecraft is not an issue,” ISRO Satellite Centre Director M. Annadurai told The Hindu.

Stunning View of Solar System’s Largest Volcano and Valles Marineris Revealed by India’s Mars Orbiter Mission

India’s Mars Orbiter Mission (MOM) has delivered another sweet treat – a stunning view of our Solar System’s largest volcano and the largest canyon.

Just days ago, MOM captured a new global image of the Red Planet dominated by Olympus Mons and Valles Marineris – which is the largest known volcano and the largest known canyon in the Solar System, respectively.

Situated right in between lies a vast volcanic plateau holding a trio of huge volcanoes comprising the Tharsis Bulge: Arsia Mons, Pavonis Mons, and Ascraeus Mons. All four volcanoes are shield volcanoes.

To give an idea of its enormity, Olympus Mons stands about three times taller than Mount Everest and is about the size of Arizona.

Olympus Mons is located in Mars’ western hemisphere and measures 624 kilometers (374 miles) in diameter, 25 km (16 mi) high, and is rimmed by a 6 km (4 mi) high scarp.

Valles Marineris is often called the “Grand Canyon of Mars.” It spans about as wide as the entire United States.

The Indian Space Research Organization (ISRO), India’s space agency which designed and developed the orbiter released the image on Oct. 17, barely two days ahead of the planet’s and spacecrafts’ extremely close encounter with comet Siding Spring.

By the way, a relieved ISRO tweeted MOM’s survival of her close shave with the once-in-a-lifetime cometary passage with gusto, soon after the swingby:

“Phew! Experience of a lifetime. Watched the #MarsComet #SidingSpring whizzing past the planet. I’m in my orbit, safe and sound.”

The new global image was taken by the tri-color camera as MOM swooped around the Red Planet in a highly elliptical orbit whose nearest point to Mars (periapsis) is at 421.7 km and farthest point (apoapsis) at 76,993.6 km, according to ISRO.

To date ISRO has released four global images of the Red Planet, including a 3-D view, reported here.

Olympus Mons, the Tharsis Bulge, and Valles Marineris are near the equator.

Valles Marineris stretches over 4,000 km (2,500 mi) across the Red Planet, is as much as 600 km wide, and measures as much as 7 kilometers (4 mi) deep.

Here’s a comparison view of the region taken by NASA’s Viking 1 orbiter in the 1970s.

MOM is India’s first deep space voyager to explore beyond the confines of her home planet’s influence and successfully arrived at the Red Planet only one month ago after the “history creating” orbital insertion maneuver on Sept. 23/24 following a ten month journey.

The $73 million MOM mission is expected to last at least six months.

MOM’s success follows closely on the heels of NASA’s MAVEN orbiter which also successfully achieved orbit barely two days earlier on Sept. 21 and could last 10 years or more.

With MOM’s arrival, India became the newest member of an elite club of only four entities that have launched probes that successfully investigated Mars – following the Soviet Union, the United States, and the European Space Agency (ESA).

Comet Siding Spring: Close Call for Mars, Wake Up Call for Earth?

Five orbiters from India, the European Union and the United States will nestle behind the Mars as comet Siding Springs passes at a speed of 200,000 km/hr (125,000 mph). At right, Comet Shoemaker-Levy 9 impacts on Jupiter, the Chelyabinsk Asteroid over Russia. (Credits: NASA,ESA, ISRO)

It was 20 years ago this past July when images of Jupiter being pummeled by a comet caught the world’s attention. Comet Shoemaker-Levy 9 had flown too close to Jupiter. It was captured by the giant planet’s gravity and torn into a string of beads. One by one the comet fragments impacted Jupiter — leaving blemishes on its atmosphere, each several times larger than Earth in size.

Until that event, no one had seen a comet impact a planet. Now, Mars will see a very close passage of the comet Siding Spring on October 19th. When the comet was first discovered, astronomers quickly realized that it was heading straight at Mars. In fact, it appeared it was going to be a bulls-eye hit — except for the margin of error in calculating a comet’s trajectory from 1 billion kilometers (620 million miles, 7 AU) away.

It took several months of analysis for a cataclysmic impact on Mars to be ruled out. So now today, Mars faces just a cosmic close shave. But this comet packs enough energy that an impact would have globally altered Mars’ surface and atmosphere.

So what should we Earthlings gather from this and other events like it? Are we next? Why or why not should we be prepared for impacts from these mile wide objects?

For one, ask any dinosaur and you will have your answer.

Adding Siding Spring to the Comet 67P atop Los Angeles provides a rough comparison of sizes. This images was expanded upon U.T.'s Bob King - "What Comets, Parking Lots and Charcoal Have in Common". (Credit: ESA, anosmicovni) — An illustration of the Siding Spring comet in comparison to the Comet 67P atop Los Angeles. The original image was the focus of Bob King’s article – “What Comets, Parking Lots and Charcoal Have in Common“. (Credit: ESA, anosmicovni)

One can say that Mars was spared as were the five orbiting spacecraft from India (Mars Orbiter Mission), the European Union (Mars Express) and the United States (MOD, MRO, MAVEN). We have Scottish-Australian astronomer Robert McNaught to thank for discovering the comet on January 3, 2013, using the half meter (20 inch) Uppsala Southern Schmidt Telescope at Siding Spring, Australia.

Initially the margin of error in the trajectory was large, but a series of observations gradually reduced the error. By late summer 2014, Mars was in the clear and astronomers could confidently say the comet would pass close but not impact. Furthermore, as observations accumulated — including estimates of the outpouring of gases and dust — comet Siding Spring shrunk in size, i.e. the estimates of potentially tens of kilometers were down to now 700 meters (4/10th of a mile) in diameter. Estimates of the gas and dust production are low and the size of the tail and coma — the spherical gas cloud surrounding the solid body — are small and only the outer edge of both will interact with Mars’ atmosphere.

The mass, velocity and kinetic energy of celestial bodies can be deceiving. It is useful to compare the Siding Spring comet to common or man-made objects.

Yet, this is a close call for Mars. We could not rule out a collision for over six months. While this comet is small, it is moving relative to Mars at a speed of 200,000 kilometers/hour (125,000 mph, 56 km/sec). This small body packs a wallop. From high school science or intro college Physics, many of us know that the kinetic energy of an object increases by the square of the velocity. Double the velocity and the energy of the object goes up by 4, increase by 3 – energy increases by 9.

So the close shave for Mars is yet another wake up call for the “intelligent” space faring beings of the planet Earth. A wake up call because the close passage of a comet could have just as easily involved Earth. Astronomers would have warned the world of a comet heading straight for us, one that could wipe out 70% of all life as happened 65 million years ago to the dinosaurs. Replace dinosaur with humans and you have the full picture.

Time would have been of the essence. The space faring nations of the world — those of the EU, and Russia, the USA, Japan and others — would have gathered and attempted to conceive some spacecrafts with likely nuclear weapons that could be built and launched within a few months. Probably several vehicles with weapons would be launched at once, leaving Earth as soon as possible. Intercepting a comet or asteroid further out would give the impulse from the explosions more time to push the incoming body away from the Earth.

There is no way that humanity could sit on their collective hands and wait for astronomers to observe and measure for months until they could claim that it would just be a close call for Earth. We could imagine the panic it would cause. Recall the scenes from Carl Sagan’s movie Contact with people of every persuasion expressing at 120 decibels their hopes and fears. Even a small comet or asteroid, only a half kilometer – a third of a mile in diameter would be a cataclysmic event for Mars or Earth.

But yet, in the time that has since transpired from discovery of the comet Siding Spring (1/3/2013), the Chelyabinsk asteroid (~20 m/65 ft) exploded in an air burst that injured 1500 people in Russia. The telescope that discovered Comet Siding Spring was decommissioned in late 2013 and the Southern Near-Earth Object Survey was shutdown. This has left the southern skies without a dedicated telescope for finding near-Earth asteroids. And proposals such as the Sentinel project by the B612 Foundation remain underfunded.

We know of the dangers from small celestial bodies such as comets or asteroids. Government organizations in the United States and groups at the United Nations are discussing plans. There is plenty of time to find and protect the Earth but not necessarily time to waste.

Glorious Global 3-D Mars from ISRO’s MOM and ESA’s Rosetta

Here’s another breathtakingly glorious view from India’s Mars Orbiter Mission (MOM) – her first global 3-D portrait of her new home careening around the Red Planet.

MOM is India’s first deep space voyager to explore beyond the confines of her home planet’s influence and just successfully arrived at the Red Planet after the “history creating” orbital insertion maneuver on Sept. 23/24 following a ten month journey.

This newly released 3-D view from MOM expands upon the initial 2-D global color view of Mars released by the Indian Space Research Organization (ISRO), India’s space agency. See below and detailed in my earlier story – here.

The 3-D image was generated from multiple pictures acquired by MOM’s on-board Mars Color Camera on Sept 28, 2014, from the very high altitude of approximately 74,500 kilometers as the spacecraft orbits Mars.

The images were taken by the tri-color camera as MOM swooped around the Red Planet in a highly elliptical orbit whose nearest point to Mars (periapsis) is at 421.7 km and farthest point (apoapsis) at 76,993.6 km, according to ISRO.

Therefore, the 3-D Red Planet portrait was captured nearly at apoapsis. And being three dimensional, it gives a stereo sense of the huge dust storm swirling over a large swath of the planet’s Northern Hemisphere set against the blackness of space.

Below right is the southern polar ice cap. To see the 3-D effect, whip out your handy pair of left-eye red, right-eye blue color anaglyph glasses.

And while we’re on the subject of spacely 3-D, it’s worth noting that another of humanity’s ground breaking probes currently making news – ESA’s comet hunting Rosetta probe – likewise snapped a glorious 3-D view of Mars way back in 2007, during the brief, but critical, gravity assist slingshot maneuver that flung Rosetta along her vast 10 year path through interplanetary space.

So by way of comparison let’s take a trip down memory lane and be sure to look back at Rosetta’s global 3-D Martian views (below) taken by the high resolution OSIRIS camera on 24 February 2007 at 19:28 CET from a distance of about 240,000 kilometers.

The Rosetta team created both color and black & white 3-D views of Mars.

The $73 million MOM mission is expected to last at least six months.

MOM’s success follows closely on the heels of NASA’s MAVEN orbiter which also successfully achieved orbit barely two days earlier on Sept. 21 and could last 10 years or more.

ISRO and NASA Ink Deal to Collaborate on Red Planet and Home Planet Science Missions

ISRO and NASA have inked a deal to collaborate on future missions to jointly explore the Red Planet and our Home Planet hot on the heels of ISRO’s wildly successful Mars Orbiter Mission (MOM), India’s first ever interplanetary voyager to explore Mars.

NASA Administrator Charles Bolden and K. Radhakrishnan, chairman of the Indian Space Research Organisation (ISRO), signed an agreement to collaborate on future science missions to explore Mars as well as to build and launch a joint NASA-ISRO mission to observe Earth.

The leaders of NASA and ISRO met in Toronto, Canada on Tuesday, Sept. 30 and “signed two documents to launch a NASA-ISRO satellite mission to observe Earth and establish a pathway for future joint missions to explore Mars,” according to a NASA statement.

Bolden and Rao met at the International Astronautical Congress underway in Toronto.

They signed one agreement defining each agency’s responsibilities for the joint NASA-ISRO Synthetic Aperture Radar (NISAR) mission, targeted to launch in 2020. NISAR will make global measurements of the causes and consequences of land surface changes.

The second agreement “establishes a NASA-ISRO Mars Working Group to investigate enhanced cooperation between the two countries in Mars exploration.”

“The signing of these two documents reflects the strong commitment NASA and ISRO have to advancing science and improving life on Earth,” said NASA Administrator Charles Bolden, in a NASA statement.

“This partnership will yield tangible benefits to both our countries and the world.”

NISAR will be the first Earth observing mission to be equipped two different synthetic aperture radar (SAR) frequencies (L-band and S-band) – one each from NASA and ISRO.

NASA will also provide “the high-rate communication subsystem for science data, GPS receivers, a solid state recorder, and a payload data subsystem.”

ISRO will provide the spacecraft bus and launch vehicle.

The radars will be able to measure subtle changes in Earth’s surface of less than a centimeter across stemming from the flow of glaciers and ice sheets as well as earthquakes and volcanoes.

Regarding Mars, the first subject the joint working group will tackle will be to coordinate observations from each nation’s recently arrived Mars orbiters – ISRO’s MOM and NASA’s MAVEN. They will also examine areas of future collaboration on surface rovers and orbiters.

“NASA and Indian scientists have a long history of collaboration in space science,” said John Grunsfeld, NASA Associate Administrator for Science.

“These new agreements between NASA and ISRO in Earth science and Mars exploration will significantly strengthen our ties and the science that we will be able to produce as a result.”

India’s MOM Snaps Spectacular Portrait of New Home – the Red Planet

MOM is truly something special.

For her latest eye popping feat, India’s Mars Orbiter Mission (MOM) has snapped the first global portrait of her new Home – the Red Planet.

MOM is India’s first interplanetary voyager and took the stupendous new image on Sept. 28, barely four days after her historic arrival on Sept. 23/24 following the successful Mars Orbital Insertion (MOI) braking maneuver.

The MOM orbiter was designed and developed by the Indian Space Research Organization (ISRO), India’s space agency, which released the image on Sept. 29.

Even more impressive is that MOM’s Martian portrait shows a dramatic view of a huge dust storm swirling over a large patch of the planet’s Northern Hemisphere against the blackness of space. Luckily, NASA’s Opportunity and Curiosity surface rovers are nowhere nearby.

“Something’s brewing here!” ISRO tweeted.

The southern polar ice cap is also clearly visible.

It was taken by the probe’s on-board Mars Color Camera from a very high altitude of 74,500 kilometers.

When MOM met Mars, the thrusters placed the probe into a highly elliptical orbit whose nearest point to Mars (periapsis) is at 421.7 km and farthest point (apoapsis) at 76,993.6 km. The inclination of the orbit with respect to the equatorial plane of Mars is 150 degrees, as intended, ISRO reported.

So the Red Planet portrait was captured nearly at apoapsis.

This is the third MOM image released by ISRO thus far, and my personal favorite. And its very reminiscent of whole globe Mars shots taken by Hubble.

MOM’s goal is to study Mars’ atmosphere, surface environments, morphology, and mineralogy with a 15 kg (33 lb) suite of five indigenously built science instruments. It will also sniff for methane, a potential marker for biological activity.

The $73 million mission is expected to last at least six months.

MOM’s success follows closely on the heels of NASA’s MAVEN orbiter which also successfully achieved orbit barely two days earlier on Sept. 21 and could last 10 years or more.

With MOM’s arrival, India became the newest member of an elite club of only four entities who have launched probes that successfully investigated Mars – following the Soviet Union, the United States and the European Space Agency (ESA).
