Just where has the Curiosity rover traveled so far and where is it going? This new video, narrated by John Grotzinger, the principal investigator for the Mars Science Laboratory mission, provides an aerial tour of the rover’s past, present and future traverses on the Red Planet.

Curosity landed in a flat, “hummocky” area in Gale Crater and is heading towards the Aeolis Mons, also known as Mount Sharp, a mountain 5 kilometers (3 miles) high. Right now the rover is among a cluster of small, steep-sided knobs, or buttes that are quite large — up to about the size of a football field and the height of a goal post. They sit in a gap in a band of dark sand dunes that lie at the foot of the mountain. Deep sand could present a hazard for driving, so this break in the dunes is the access path to the mountain.
These buttes have been named the Murray Buttes in honor of influential planetary scientist Bruce Murray (1931-2013).

“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,” said NASA Mars Exploration Program Manager Fuk Li from JPL. “It is fitting that the rover teams have chosen his name for significant landmarks on their expeditions.”

Meanwhile at Endeavour Crater, where the Opportunity is still exploring, nearly a decade on, and is now preparing for winter. A feature there has also been named for Bruce Murray, Murray Ridge, part of an uplifted crater rim.

“Murray Ridge is the highest hill we’ve ever tried to climb with Opportunity,” said the mission’s principal investigator, Steve Squyres of Cornell University, Ithaca, N.Y. The ridge has outcrops with clay minerals detected from orbit. It also provides a favorable slope for Martian winter sunshine to hit the rover’s solar panels, an advantage for keeping Opportunity mobile through the winter.

“Bruce Murray is best known for having been the director of JPL, and JPL is where our rovers were built,” Squyres said. “He led JPL during a time when the planetary exploration budget was under pressure and the future for planetary missions was not clear. His leadership brought us through that period with a strong exploration program. He was also a towering figure in Mars research. His papers are still cited abundantly today.”

Back to the video, interestingly, the “fly-through” data comes from a variety of missions representing some of the history of Mars exploration. Doug Ellison, who works with JPL’s Eyes on the Solar System – which uses spacecraft data to create realistic simulated views of spacecraft, planets and other features within our solar system – said on Twitter that the video uses data from Viking to narrow down the color, Mars Express High Resolution Stereo Camera (MEX-HRSC_ and the Mars Reconnassaince Oribiter’s HiRISE camera for topography, and the MRO Context camera (MRO-CTX) and HiRISE for imagery.

The Day the Earth Smiled: Saturn Shines in this Amazing Image from the Cassini Team

The "pale blue dot" of Earth as seen from Cassini on July 19, 2013.

This summer, for the first time ever, the world was informed that its picture was going to be taken from nearly a billion miles away as the Cassini spacecraft captured images of Saturn in eclipse on July 19. On that day we were asked to take a moment and smile and wave at Saturn, from wherever we were, because the faint light from our planet would be captured by Cassini’s camera, shielded by Saturn from the harsh glare of the Sun.

A few preliminary images were released just a few days later showing the “pale blue dot” of Earth nestled within the glowing bands of Saturn’s rings. It was an amazing perspective of our planet, and we were promised that the full mosaic of Cassini images was being worked on and would be revealed in the fall.

Well, it’s fall, and here it is:

The full mosaic from the Cassini imaging team of Saturn on July 19, 2013... the "Day the Earth Smiled"
The full mosaic from the Cassini imaging team of Saturn on July 19, 2013… the “Day the Earth Smiled”

Simply beautiful!

Cassini Imaging Team leader Carolyn Porco wrote on her Facebook page:

“After much work, the mosaic that marks that moment the inhabitants of Earth looked up and smiled at the sheer joy of being alive is finally here. In its combination of beauty and meaning, it is perhaps the most unusual image ever taken in the history of the space program.”

In this panorama of the Saturnian system, a view spanning 404,880 miles (651,591 km), we see the planet silhouetted against the light from the Sun. It’s a unique perspective that highlights the icy, reflective particles that make up its majestic rings and also allows our own planet to be seen, over 900 million miles distant. And it’s not just Earth that was captured, but the Moon, Venus, and Mars were caught in the shot too.

According to the description on the CICLOPS page, “Earth’s twin, Venus, appears as a bright white dot in the upper left quadrant of the mosaic… between the G and E rings. Mars also appears as a faint red dot embedded in the outer edge of the E ring, above and to the left of Venus.”

This was no simple point-and-click. Over 320 images were captured by Cassini on July 19 over a period of four hours, and this mosaic was assembled from 141 of those images. Because the spacecraft, Saturn, and its moons were all in constant motion during that time, affecting not only positions but also levels of illumination, imaging specialists had to adjust for that to create the single image you see above. So while all elements may not be precisely where they were at the same moment in time, the final result is no less stunning.

“This version was processed for balance and beauty,” it says in the description. (And I’ve no argument with that.)

Russia’s Second Shot at Phobos May Return Bits of Mars As Well

The streaked and stained surface of Phobos. (Image: NASA)

After the tragic failure of the first Phobos-Grunt mission to even make it out of low-Earth orbit, the Russian space agency (Roscosmos) is hoping to give it another go at Mars’ largest moon with the Phobos-Grunt 2 mission in 2020. This new-and-improved version of the spacecraft will also feature a lander and return stage, and, if successful, may not only end up sending back pieces of Phobos but of Mars as well.


The origins of Phobos have long been a topic of planetary science debate. Did it form with Mars as a planet? Is it a wayward asteroid that ventured too closely to Mars? Or is it a chunk of the Red Planet blasted up into orbit from an ancient impact event? Only in-depth examination of its surface material will allow scientists to determine which scenario is most likely (or if the correct answer is really “none of the above”) and Russia’s ambitious Phobos-Grunt mission attempted to become the first ever to not only land on the 16-mile-wide moon but also send samples back to Earth.

Unfortunately it wasn’t in the cards. After launching on Nov. 9, 2011, Phobos-Grunt’s upper stage failed to ignite, stranding it in low-Earth orbit. After all attempts to re-establish communication and control of the ill-fated spacecraft failed, Phobos-Grunt crashed back to Earth on Jan. 15, impacting in the southern Pacific off the coast of Chile.

But with a decade of development already invested in the mission, Roscosmos is willing to try again. “Ad astra per aspera,” as it’s said, and Phobos-Grunt 2 will attempt to overcome all hardships in 2020 to do what its predecessor couldn’t.

And, according to participating researchers James Head and Kenneth Ramsley from Brown University in Providence, Rhode Island, the sample mission could end up being a “twofer.”

Orbiting at an altitude of only 5,840 miles (9,400 km) Phobos has been passing through plumes material periodically blown off of Mars by impact events. Its surface soil very likely contains a good amount of Mars itself, scooped up over the millennia.

“When an impactor hits Mars, only a certain of proportion of ejecta will have enough velocity to reach the altitude of Phobos, and Phobos’ orbital path intersects only a certain proportion of that,” said Ramsley, a visiting researcher in Brown’s planetary geosciences group. “So we can crunch those numbers and find out what proportion of material on the surface of Phobos comes from Mars.”

Determining that ratio would then help figure out where Phobos was in Mars orbit millions of years ago, which in turn could point at its origins.

“Only recently — in the last several 100 million years or so — has Phobos orbited so close to Mars,”  Ramsley said. “In the distant past it orbited much higher up. So that’s why you’re going to see probably 10 to 100 times higher concentration in the upper regolith as opposed to deeper down.”

In addition, having an actual sample of Phobos (along with stowaway bits of Mars) in hand on Earth, as well as all the data acquired during the mission itself, would give scientists invaluable insight to the moon’s as-yet-unknown internal composition.

“Phobos has really low density,” said Head, professor of geological sciences at Brown and an author on the study. “Is that low density due to ice in its interior or is it due to Phobos being completely fragmented, like a loose rubble pile? We don’t know.”

The study was published in Volume 87 of Space and Planetary Science (Mars impact ejecta in the regolith of Phobos: Bulk concentration and distribution.)

India’s Mars Orbiter Mission (MOM) Requires Extra Thruster Firing after Premature Engine Shutdown

India’s Mars Orbiter Mission (MOM) probe suffered a surprise hiccup overnight (Nov. 11 IST) when the main engine shut down prematurely and left the country’s first ever mission to the Red Planet flying in a significantly lower than planned interim elliptical orbit around Earth – following what was to be her 4th orbit raising burn since last week’s flawless launch.

MOM is in normal health,” at this time according to the Indian Space Research Organization (ISRO) – which has now scheduled a supplementary main engine firing for early Tuesday (Nov. 12) to boost the crafts orbit the missing 20,000 km required.

Monday’s engine firing only raised MOM’s apogee (farthest point to Earth) from 71,623 km to 78,276 km compared to the originally planned apogee of about 100,000 [1 lakh] km), said ISRO in a press release.

This is the first serious problem to strike MOM in space. And it seemed clear to me something might be amiss when ISRO failed to quickly announce a successful completion of the 4th firing as had been the pattern for the initial three burns.

The premature shutdown of the liquid fueled 440 Newton main engine “imparted an incremental velocity of 35 metres/second as against 130 metres/second originally planned,” ISRO stated.

That’s barely a quarter of what was hoped for.

“A supplementary orbit-raising operation is planned tomorrow (November 12, 2013) at 0500 hrs IST to raise the apogee to nearly 1 lakh [100,000] km.”

A series of six absolutely essential firings of the 440 Newton main engine – dubbed “midnight maneuvers” – had been originally scheduled by Indian space engineers.

The purpose of the “midnight maneuvers” is to achieve Earth escape velocity by gradually raising MOM’s apogee over several weeks, and set her on a trans Mars trajectory to the Red Planet, following the spectacular blastoff on Nov. 5 from India’s spaceport.

MOM was due to depart Earth’s orbit on Dec. 1 after accomplishing the 6th of the originally scheduled thruster firings – and begin a 10 month long interplanetary cruise to Mars.

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.

The 1st, 2nd and 3rd thruster firings were spot on and incrementally raised MOM’s apogee from 23556 km to 28814 km, 40186 km and 71,623 km respectively.

The next firing had been slated for Nov. 16.

Here’s how ISRO described the source of the main engine shutdown:

“During the fourth orbit-raising operations held today (November 11, 2013), the redundancies built-in for the propulsion system were exercised, namely, (a) energising the primary and redundant coils of the solenoid flow control valve of 440 Newton Liquid Engine and (b) logic for thrust augmentation by the attitude control thrusters, when needed.

However, when both primary and redundant coils were energised together, as one of the planned modes, the flow to the Liquid Engine stopped. The thrust level augmentation logic, as expected, came in and the operation continued using the attitude control thrusters. This sequence resulted in reduction of the incremental velocity.”

It is not known at this time how or whether the requirement for a supplemental “midnight maneuver” engine firing will affect the mission’s timing at Earth and its operations and longevity at Mars.

Why are the firings called midnight maneuvers?

“Firing has to happen near the perigee and in the visibility from ISTRAC ground stations. All these orbits have argument of perigee of ~285 deg. When all these constraints are put together, firings time will almost always fall in to midnights of Indian sub continent,” said ISRO in response to a readers inquiry.

In the latest update, ISRO reports: “After achieving an apogee of around 78,000 km in last night’s Maneuver, ISRO’s Mars Orbiter Mission Spacecraft is all set to reach the apogee of One lakh km in a supplementary maneuver scheduled for 5 AM tomorrow. [Nov 12].”

MOM was to arrive in the vicinity of Mars on September 24, 2014 when the absolutely essential Mars orbital insertion firing by the 440 Newton liquid fueled main engine will slow the probe and place it into a 366 km x 80,000 km elliptical orbit.

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

The low cost $69 Million MOM mission is the first of two new Mars orbiter science probes from Earth blasting off for the Red Planet this November.

Half a world away, NASA’s $671 Million MAVEN orbiter remains on target to launch in less than one week on Nov. 18 – from Cape Canaveral, Florida.

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.

The MAVEN and MOM science teams will “work together” to unlock the secrets of Mars atmosphere and climate history, MAVEN’s top scientist Prof. Bruce Jakosky told Universe Today.

With India’s Mars Orbiter Mission (MOM) safely and flawlessly injected into her initial elliptical Earth parking orbit following Tuesday’s (Nov. 5) spectacular launch, the flight has quickly transitioned to the next stage – the crucial series of thruster firings to raise MOM’s orbit around Earth dubbed “Midnight Maneuvers” and achieve escape velocity.

Barely a day after blastoff, ISRO engineers successfully completed the first of six orbit raising “Midnight Maneuver” burns at 01:17 hrs IST today (Nov. 6) with MOM’s liquid fueled thruster – see graphic below.

The goal is to gradually maneuver MOM – India’s 1st mission to the Red Planet – into a hyperbolic trajectory so that the spacecraft will escape from the Earth’s Sphere of Influence (SOI) and eventually arrive at the Mars Sphere of Influence after a 10 month interplanetary cruise.

To do this involves a lot of complicated orbital mechanics calculations, as noted by ISRO’s chief during the launch webcast.

“The journey has only begun. The challenging phase is coming,” said Dr. K. Radhakrishnan, Chairman ISRO.

India’s PSLV rocket is not powerful enough to send MOM on a direct flight to Mars.

The launch “placed MOM very precisely into an initial elliptical orbit around Earth of 247 x 23556 kilometers with an inclination of 19.2 degrees,” said Radhakrishnan. “MOM is a huge step taking India beyond Earth’s influence for the first time.”

So ISRO’s engineers devised a clever procedure to get the spacecraft to Mars on the least amount of fuel via six “Midnight Maneuver” engine burns over the next several weeks – and at an extremely low cost.

The 440 Newton engine fires when MOM is at its closest point in orbit above Earth. This increases the ships velocity and gradually widens the ellipse and raises the apogee of the six resulting elliptical orbits around Earth that eventually injects MOM onto the Trans-Mars trajectory.

The 1st firing lasted 416 seconds and raised the spacecraft’s apogee to 28,825 km and perigee to 252 km.

The remaining burns are planned for November 7, 8, 9, 11, and 16.

MOM is expected to achieve escape velocity on Dec. 1 and depart Earth’s sphere of influence tangentially to Earth’s orbit to begin the 300 day long voyage to the Red Planet.

She will follow a path that’s roughly half an ellipse around the sun.

MOM arrives in the vicinity of Mars on September 24, 2014 for the absolutely essential Mars orbital insertion firing by the 440 Newton liquid fueled main engine which slows the probe and places it into a 366 km x 80,000 km elliptical orbit.

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).

India flawlessly launched its first ever mission to Mars today (Nov. 5) to begin a history making ten month long interplanetary voyage to the Red Planet that’s aimed at studying the Martian atmosphere and searching for methane after achieving orbit.

The Mars Orbiter Mission (MOM) thundered to space atop the nations four stage Polar Satellite Launch Vehicle (PSLV) precisely on time at 14:38 hrs IST (9:08 UTC, 4:08 a.m. EST) from the Indian Space Research Organization’s (ISRO) Satish Dhawan Space Centre SHAR, Sriharikota, off India’s east coast.

“Our journey to Mars begins now!” announced an elated ISRO Chairman K. Radhakrishnan at the ISRO spaceport during a live broadcast of MOM’s launch from the mission control center. “We achieved orbit and we can all be proud.”

“I’m extremely happy to announce that the PSLV-C25 vehicle has placed the Mars orbiter spacecraft very precisely into an elliptical orbit around Earth of 247 x 23556 kilometers with an inclination of 19.2 degrees,” Radhakrishnan said, after “much meticulous planning and hard work by everyone.”

ISRO announced that MOM separated from the PSLV 4th stage as planned some 44 minutes after liftoff and that the solar panels successfully deployed.

Confirmation of the 4th stage ignition and spacecraft separation was transmitted by ship-borne terminals aboard a pair of specially dispatched tracking ships – SCI Nalanda and SCI Yamuna – stationed by ISRO in the South Pacific Ocean.

MOM was designed and developed by the Indian Space Research Organization (ISRO) in near record time after receiving approval from the Indian Prime Minister Manmohan Singh in August 2012.

“No mission is beyond our capability”, said Radhakrishnan. “MOM is a huge step taking India beyond Earth’s influence for the first time.”

A series of six burns over the next month will raise the apogee and put MOM on a trajectory for Mars around December 1.

Following a 300 day interplanetary cruise phase, the do or die Mars orbital insertion firing by the main engine on September 24, 2014 will place MOM into an 366 km x 80,000 km elliptical orbit.

If all continues to goes well with MOM, India will join an elite club of 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).

MOM is the first of two new Mars orbiter science probes from Earth blasting off for the Red Planet this November. Half a globe away, NASA’s $671 Million MAVEN orbiter remains on target to launch barely two weeks after MOM on Nov. 18 – from Cape Canaveral, Florida.

The 1,350 kilogram (2,980 pound) MOM orbiter is also known as ‘Mangalyaan’ – which in Hindi means ‘Mars craft.’

Although the 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.

MOM and MAVEN will arrive nearly simultaneously in Mars orbit next September – joining Earth’s invasion fleet of five operational orbiters and intrepid surface rovers currently unveiling the mysteries of the Red Planet.

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 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 $69 Million ‘Mangalyaan’ mission is expected to continue gathering measurements at the Red Planet for about six to ten months and hopefully much longer.

Stay tuned here for continuing MAVEN and MOM news and my MAVEN launch reports from on site at the Kennedy Space Center press center.

A Dark and Dusty Avalanche on Mars

Mars may be geologically inactive but that doesn’t mean there’s nothing happening there — seasonal changes on the Red Planet can have some very dramatic effects on the landscape, as this recent image from the HiRISE camera shows!

When increasing light from the springtime Sun warms up the sides of sheer cliffs made from countless layers of water and carbon dioxide ice near Mars’ north pole, some of that CO2 ice sublimes, sending cascades of loose soil and dust down to the terraced base below. This uncovered material stains the frost-covered polar surface dark, outlining the paths of avalanches for HiRISE to easily spot from orbit. (See the original HiRISE image here.)

Circling Mars since March 2006, the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter has even captured some of these polar landslides in action.

The rust-colored avalanche shown above has fallen hundreds of meters from the middle of a layered ice deposit, spreading nearly a kilometer across the frozen ridges at the base of the cliff. The view was acquired on Sept. 13, 2013.

Check out a video explaining this view and the processes that created it below, narrated by Phil Plait (aka the Bad Astronomer).

Mars’ seasonal polar caps are composed primarily of carbon dioxide frost. This frost sublimates (changes from solid directly to gas) in the spring, boosting the pressure of Mars’ thin atmosphere. In the fall the carbon dioxide condenses, causing the polar caps to reach as far as ~55 degrees latitude by late winter. By learning about current processes on a local level we can learn more about how to interpret the geological record of climate changes on Mars. (Source)

MOM is spending her last night on Earth – and she’s a Mind-Blowing Midnight Marvel !

The pride of all India, and everyone’s favorite MOM is healthy and set to embark on the nation’s first ever interplanetary voyage of exploration. She aims to conduct a detailed study of the Martian atmosphere and sniff for methane – a potential indicator for life.

The Mars Orbiter Mission (MOM) was designed and developed by the Indian Space Research Organization (ISRO) which is broadcasting a live webcast of the launch starting at 14:00 hrs IST, 3:30 a.m. EST at – http://isro.org/

“All vehicle systems have been switched ON,” as of now, says ISRO.

Now less than 8 hours from blastoff, the PSLV-C25 booster rocket is fully fueled and poised to streak from ISRO’s Satish Dhawan Space Centre SHAR, Sriharikota, located on India’s east coast in Andhra Pradesh state.

If all goes well with MOM, India joins an elite club of 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).

Reaching Mars successfully is an enormous technological challenge. More than half of all Earth’s attempts have failed. But those who fail to ‘dare mighty things’ are doomed to timidity and ignominy.

ISRO reports that the weather outlook is favorable for an on time launch on Nov 05, 2013 at 14:38 hrs IST (9:08 UTC, 4:08 a.m. EST).

“Weather Forecast for launch day based on today’s image from Kalpana Meteorological Satellite: Early morning, cloudy and low probability of Rain, No severe weather expected. During launch window – partly cloudy weather and no rain is expected.”

“Looks like we are heading towards a bright and sunny day for the launch,” says ISRO.

Just hours ago the final loading of propellants into the rocket’s liquid fueled second stage (PS2) with highly toxic nitrogen tetroxide and hydrazine was satisfactorily completed.

The launch gantry has been retracted to a distance of 50 meters and the 44 meter (144 foot) tall four stage PSLV booster stands at the ready under the gaze of the starry night.

Two tracking ships – SCI Nalanda and SCI Yamuna – have been deployed to the Indian Ocean.

They are now in position to relay critical in flight telemetry during the ignition of the PSLV-C25 fourth stage and the spacecraft’s separation from the rocket at T plus 44 minutes.

“For about ten minutes between the separation of third stage of PSLV and ignition of fourth stage the vehicle will not be visible from any ground stations as will be evident in the Live telecast,” says ISRO.

And the launch team is leaving no stone unturned to ensure success!

“As the country gets embraced in deep sleep – don’t forget a few hundred tireless minds at ISRO – rock-steady on their consoles and keeping their strict vigil on the several health parameters of the rocket and the MoM spacecraft,” said ISRO in a statement.

And here’s a poetic tribute to MOM from ISRO

1391674_1392844634286810_1481308204_n

MOM is the first of two new Mars orbiter science probes from Earth set to blast off for the Red Planet this November. On the other side of Earth, NASA’s MAVEN orbiter remains on target to launch barely two weeks after MOM on Nov. 18 – from Cape Canaveral, Florida.

The 1,350 kilogram (2,980 pound) MOM orbiter is also known as‘Mangalyaan’ – which in Hindi means ‘Mars craft.’

‘Mangalyaan’ is outfitted with an array of five indigenous science instruments 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.

The PSLV will inject MOM into an initially elliptical Earth parking orbit of 248 km x 23,500 km. A series of six orbit raising burns will eventually place MOM on a trajectory to Mars around December 1.

A complex network of ground stations, as indicated in the image, has been laid out for keeping an eye on the various phases of PSLV-C25/ ISRO's Mars Orbiter Mission, including the launch, Earth bound maneuvers, Heliocentric phase as well as the Martian phase.  Additionally, two ship borne terminals have also been deployed in the southern Pacific Ocean to cover critical events during the launch phase. After satellite separation from the launch vehicle, the Spacecraft  operations are controlled from the Spacecraft Control Centre of ISRO Telemetry, Tracking And Command Network (ISTRAC) in Bangalore.

Following a 300 day interplanetary cruise phase, the do or die orbital insertion engine will fire on September 24, 2014 and place MOM into an 366 km x 80,000 km elliptical orbit.

MOM and MAVEN both arrive in Mars orbit within days of one another next September – joining Earth’s invasion fleet of five operational orbiters and intrepid surface rovers currently unveiling the mysteries of the Red Planet.

The countdown has commenced and the excitement is building for India’s Mars Orbiter Mission (MOM) – which will conduct a detailed study of the Martian atmosphere and is the nation’s first ever mission to the Red Planet.

The 56 hour 30 min countdown started at 6:06 a.m. IST today (Nov. 3), according to an official statement from the Indian Space Research Organization (ISRO) leading to liftoff on Tuesday, Nov 5, from a seaside launch pad in Sriharikota, India.

MOM is the first of two new Mars orbiter science probes from Earth set to blast off for the Red Planet this November. Half a globe away, NASA’s MAVEN orbiter remains on target to launch barely two weeks after MOM on Nov. 18 – from the Florida Space Coast.

ISRO will broadcast the momentous MOM launch live at – starting at 14:00 hrs IST.

“The Launch Authorisation Board has approved & cleared the PSLV-C25/Mars Orbiter Mission launch on Nov 05, 2013 at 14:38 hrs IST (9:08 UTC, 4:08 a.m. EST)” from the state-of-the-art Satish Dhawan Space Centre SHAR, Sriharikota, located on India’s east coast in Andhra Pradesh state.

MOM is on schedule to lift off atop the powerful, extended XL version of India’s highly reliable four stage Polar Satellite Launch Vehicle (PSLV-C25).

Fueling of the PSLV-C25/Mars Orbiter Mission rocket stages is now in progress following a completely successful dress rehearsal and launch countdown exercise completed on Oct. 31.

“The filling of propellants into the Roll Control Thrusters as well as the Fourth stage of the PSLV C25 rocket [with mixed nitrogen oxides and monomethylhydrazine] is completed,” ISRO declared a short while ago.

During the dress rehearsal the vehicle systems were powered, the health was normal and the spacecraft & launch vehicle integrated level checks were completed.

Two tracking ships have been deployed to the Indian Ocean to relay critical in flight telemetry.

The 44 meter (144 ft) PSLV will launch MOM into an initially elliptical Earth parking orbit of 248 km x 23,500 km. A series of six orbit raising burns will eventually dispatch MOM on a trajectory to Mars around December 1.

Following a 300 day interplanetary cruise phase, the do or die Mars orbital insertion engine will fire on September 21, 2014 and place MOM into an 366 km x 80,000 km elliptical orbit.

MOM arrives about the same time as NASA’s MAVEN orbiter. They will significantly bolster Earth’s armada of five operational orbiters and surface rovers currently investigating the Red Planet.

MAVEN and MOM will “work together” to help solve the mysteries of Mars atmosphere, the chief MAVEN scientist told Universe Today.

“We plan to collaborate on some overlapping objectives,” Bruce Jakosky told me. Jakosky is MAVEN’s principal Investigator from the University of Colorado at Boulder.

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 ExoMarsTrace Gas Orbiter.

Although there are no NASA instruments on board MOM, NASA is providing key communications and navigation support to ISRO and MOM through the agency’s trio of huge tracking antennas in the Deep Space Network (DSN).

“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,” MAVEN’s PI Jakosky told me.

“We agreed on the value of collaboration and will hold real discussions at a later time,” he noted.

India would become only the 4th nation or entity from Earth to survey Mars up close with spacecraft, following the Soviet Union, the United States and the European Space Agency (ESA)- if all goes well.

Past attempts to reach the Red Planet from both China and Japan have unfortunately failed.

Some observers speculate that India’s MOM mission will ignite a new Asian Space Race.

The $69 Million ‘Mangalyaan’ mission is expected to continue gathering measurements at the Red Planet for at least six months and hopefully much longer.

Long live MOM !

MAVEN and MOM Missions from NASA and India Plan Martian Science Collaboration in Orbit

MAVEN is NASA’s next Mars orbiter and is due to blastoff on Nov. 18 from Cape Canaveral, Florida. It will study the evolution of the Red Planet’s atmosphere and climate.

After years of hard work by dedicated science and engineering teams, a new pair of Mars orbiter science missions from Earth are in the final stages of prelaunch processing and are nearly set to blast off for the Red Planet in November.

If all goes well, NASA’s MAVEN orbiter and India’s MOM (Mars Orbiter Mission) will “work together” to help solve the mysteries of Mars atmosphere, the chief MAVEN scientist told Universe Today at a NASA briefing today (Oct. 28).

“We plan to collaborate on some overlapping objectives,” Bruce Jakosky told me. Jakosky is MAVEN’s principal Investigator from the University of Colorado at Boulder.

MAVEN and MOM will join Earth’s armada of five operational orbiters and surface rovers currently exploring the Red Planet.

MOM is India’s first mission to Mars. Its also first in line to this year’s Martian on ramp and is slated to lift off in barely one week on Nov. 5 atop the most powerful version of the Polar Satellite Launch Vehicle (PSLV) rocket from a seaside launch pad in Srihanikota, India.

The 1,350 kilogram (2,980 pound) MOM orbiter, also known as ‘Mangalyaan’, is the brainchild of ISRO, the Indian Space Research Organization.

NASA’s Mars Atmosphere and Volatile EvolutioN Mission (MAVEN) spacecraft launches in three weeks on Nov. 18 atop a United Launch Alliance Atlas V 401 rocket from a seaside pad on Cape Canaveral Air Force Station, Florida.

Both MAVEN and MOM will study the Red Planets atmosphere. Although they are independent and carrying different science payloads the two missions do have some common goals.

“There are some overlapping objectives between MAVEN and MOM,” Jakosky said.

“We have had some discussions with the MOM science team.”

Both orbiters are due to arrive at Mars in September 2014 after 10 month interplanetary cruises and will enter different elliptical orbits after main engine braking burns.

MAVEN is the first spacecraft from Earth devoted to investigating and understanding the upper atmosphere of Mars.

The purpose is to study specific processes and determine how and why Mars lost virtually all of its atmosphere billions of years ago and what effect that had on the history of climate change and habitability.

“The major questions about the history of Mars center on the history of its climate and atmosphere and how that’s influenced the surface, geology and the possibility for life,” said Jakosky.

“MAVEN will focus on understanding the history of the atmosphere, how the climate has changed through time, and how that influenced the evolution of the surface and the potential for habitability by microbes on Mars.”

“We don’t know the driver of the change.”

“Where did the water go and where did the carbon dioxide go from the early atmosphere? What were the mechanisms?”

“That’s what driving our exploration of Mars with MAVEN,” said Jakosky.

One of the significant differences between MOM and MAVEN regards methane detection – which is a potential marker for Martian life. Some 90% of Earth’s atmospheric methane derives from living organisms.

MOM has a methane sensor but not MAVEN.

“We just had to leave that one off to stay focused and to stay within the available resources ,” Jakosky told me.

MAVEN carries nine sensors in three instrument suites.

The Particles and Fields Package, provided by the University of California at Berkeley with support from CU/LASP and NASA’s Goddard Space Flight Center in Greenbelt, Md., contains six instruments to characterize the solar wind and the ionosphere of Mars. The Remote Sensing Package, built by CU/LASP, will determine global characteristics of the upper atmosphere and ionosphere. The Neutral Gas and Ion Mass Spectrometer, built by Goddard, will measure the composition of Mars’ upper atmosphere.

MOM’s science complement comprises the tri color Mars Color Camera to image the planet and its two moons, Phobos and Deimos; the Lyman Alpha Photometer to measure the abundance of hydrogen and deuterium and understand the planets water loss process; a Thermal Imaging Spectrometer to map surface composition and mineralogy, the MENCA mass spectrometer to analyze atmospheric composition, and the Methane Sensor for Mars to measure traces of potential atmospheric methane down to the ppm level.

“We agreed on the value of collaboration and will hold real discussions at a later time,” he noted.

NASA is providing key communications and navigation support to ISRO and MOM through the agency’s trio of huge tracking antennas in the Deep Space Network (DSN).

Over the course of its one-Earth-year primary mission, MAVEN will observe all of Mars’ latitudes at altitudes ranging from 93 miles to more than 3,800 miles.

MAVEN will execute five deep dip maneuvers during the first year, descending to an altitude of 78 miles. This marks the lower boundary of the planet’s upper atmosphere.

MAVEN has sufficient fuel reserves on board to continue observations for more than a decade.

The spacecraft will function as an indispensible orbital relay by transmitting surface science data through the “Electra” from NASA’s ongoing Curiosity and Opportunity rovers as well as the planned 2020 rover.

Stay tuned here for continuing MAVEN and MOM news and my launch reports from on site at the Kennedy Space Center press center.
