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.

“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 told me.

“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.

Stunning New Flyover Video: Volcanoes, Canyons and Craters of Mars

Mars Express over water-ice crater. ESA Celebrates 10 Years since the launch of Mars Express. This artists concept shows Mars Express set against a 35 km-wide crater in the Vastitas Borealis region of Mars at approximately 70.5°N / 103°E. The crater contains a permanent patch of water-ice that likely sits upon a dune field – some of the dunes are exposed towards the top left in this image. Copyright ESA/DLR/FU-Berlin-G.Neukum

Go from the highest volcano to the deepest canyon on Mars in this great new complication video from images taken by ESA’s Mars Express. The data shown here was gathered from the nearly 12,500 orbits by the Mars Express spacecraft since its arrival at the Red Planet in late 2003, and used to create digital topographic models of almost the entire surface of the planet. Not only does this provide unique and stunning visualization to create these “flyovers” of various locals on Mars, it also enables researchers to acquire new and surprising information about the evolution of the Red Planet.

The images in this movie were taken by the High Resolution Stereo Camera and the video was released by the DLR German Aerospace Center as part of the ten years of Mars Express celebrations in June 2013, and was just released online today.

See below a gallery of Earth from Juno[/caption]

During a crucial speed boosting slingshot maneuver around Earth on Oct. 9, NASA’s Jupiter-bound Juno probe snapped a dazzling gallery of portraits of our Home Planet over the South American coastline and the Atlantic Ocean. See our mosaics of land, sea and swirling clouds above and below, including several shown in false color.

But an unexpected glitch during the do or die swing-by sent the spacecraft into ‘safe mode’ and delayed the transmission of most of the raw imagery and other science observations while mission controllers worked hastily to analyze the problem and successfully restore Juno to full operation on Oct. 12 – but only temporarily!

Because less than 48 hours later, Juno tripped back into safe mode for a second time. Five days later engineers finally recouped Juno and it’s been smooth sailing ever since, the top scientist told Universe Today.

“Juno is now fully operational and on its way to Jupiter,” Juno principal investigator Scott Bolton told me today. Bolton is from the Southwest Research Institute (SwRI), San Antonio, Texas.

“We are completely out of safe mode!”

NASA's Juno probe captured the image data for this composite picture during its Earth flyby on Oct. 9 over Argentina, South America and the southern Atlantic Ocean. Raw imagery was reconstructed and aligned by Ken Kremer and Marco Di Lorenzo, and false-color blue has been added to the view taken by a near-infrared filter that is typically used to detect methane.

With the $1.1 Billion Juno probe completely healthy once again and the nail-biting drama past at last, engineers found the time to send the stored photos and research data back to ground station receivers.

“The science team is busy analyzing data from the Earth flyby,” Bolton informed me.

The amateur image processing team of Ken Kremer and Marco Di Lorenzo has stitched together several portraits from raw images captured as Juno sped over Argentina, South America and the South Atlantic Ocean and within 347 miles (560 kilometers) of the surface. We’ve collected the gallery here for all to enjoy.

Several portraits showing the swirling clouds and land masses of the Earth’s globe have already been kindly featured this week by Alan Boyle at NBC News and at the Daily Mail online.

Raw images from the Junocam camera are collected in strips – like a push broom. So they have to be carefully reconstructed and realigned to match up. But it can’t be perfect because the spacecraft is constantly rotating and its speeding past Earth at over 78,000 mph.

So the perspective of Earth’s surface features seen by Junocam is changing during the imaging.

And that’s what is fascinating – to see the sequential view of Earth’s beautiful surface changing as the spacecraft flew over the coast of South America and the South Atlantic towards Africa – from the dayside to the nightside.

It’s rare to get such views since only a few spacecraft have swung by Earth in this manner – for example Galileo and MESSENGER – on their way to distant destinations.

Coincidentally this week, the Cygnus cargo carrier departed the ISS over South America.

Fortunately, the Juno team knew right from the start that the flyby of Earth did accomplish its primary goal of precisely targeting Juno towards Jupiter – to within 2 kilometers of the aim point, despite going into safe mode.

“We are on our way to Jupiter as planned,” Juno Project manager Rick Nybakken, told me in a phone interview soon after the flyby of Earth. Nybakken is from NASA’s Jet Propulsion Lab in Pasadena, CA.

“None of this affected our trajectory or the gravity assist maneuver – which is what the Earth flyby is,” he said.

It also accelerated the ships velocity by 16,330 mph (26,280 km/h) – thereby enabling Juno to be captured into polar orbit about Jupiter on July 4, 2016.

The safe mode did not impact the spacecraft’s trajectory one smidgeon!

It was likely initiated by an incorrect setting for a fault protection trigger for the spacecraft’s battery when Juno was briefly in an eclipse during the flyby.

Nybakken also said that the probe was “power positive and we have full command ability,” while it was in safe mode.

Safe mode is a designated fault protective state that is preprogrammed into spacecraft software in case something goes amiss. It also aims the craft sunwards thereby enabling the solar arrays to keep the vehicle powered.

The Earth flyby maneuver was necessary because the initial Atlas V rocket launch on Aug. 5, 2011 from Cape Canaveral Air Force Station, FL was not powerful enough to place Juno on a direct trajectory flight to Jupiter.

As of today, Juno is more than was 6.7 million miles (10.8 million kilometers) from Earth and 739 million miles (7.95 astronomical units) from Jupiter. It has traveled 1.01 billion miles (1.63 billion kilometers, or 10.9 AU) since launch.

With Juno now on course for our solar system’s largest planet, there won’t be no any new planetary images taken until it arrives at the Jovian system in 2016. Juno will then capture the first ever images of Jupiter’s north and south poles.

We have never seen Jupiter’s poles imaged from the prior space missions, and it’s not possible from Earth.

During a year long mission at Jupiter, Juno will use its nine science instruments to probe deep inside the planet to reveal its origin and evolution.

“Jupiter is the Rosetta Stone of our solar system,” says Bolton. “It is by far the oldest planet, contains more material than all the other planets, asteroids and comets combined and carries deep inside it the story of not only the solar system but of us. Juno is going there as our emissary — to interpret what Jupiter has to say.”

Based on what we’ve seen so far, Junocam is sure to provide spectacular views of the gas giants poles and cloud tops.

Only 982 days to go !

What If Earth Was Threatened by An Asteroid Strike? Astronaut Panel Brings Up Ideas To Search, Deflect These Threats

“If we get hit 20 years from now, that’s not bad luck. That’s stupidity.”

That’s what former NASA astronaut Ed Lu has to say about asteroids and our efforts to search for them. He delivered those comments at a panel discussion today at New York’s American Museum of Natural History. He and several other astronauts spoke on behalf of the Association of Space Explorers (which, as the name implies, consists of astronauts, cosmonauts and the like.)

We guess that as astute readers of our publication, you know that a planetary threat from asteroids (and comets) exists. And there’s certainly more we can do; when that 17-meter asteroid blasted Russia earlier this year, Lu said most space agencies learned about it from social media!

So what’s being done about these threats? Here’s a roundup of the panel discussion’s information and some related information.

Asteroid searching and deflection:

Since Lu is the CEO of the B612 Foundation, there was a heavy emphasis on the agency’s proposed Sentinel telescope. Intended to launch in 2018, it would survey the solar system in infrared and seek out potential hazards.
To date, NASA’s NEO Observations Program has found 95 per cent of near-Earth objects larger than one kilometer, Jet Propulsion Laboratory scientist Amy Mainzer told Universe Today in a separate conversation today.
Mainzer also brought us up to speed on the Near-Earth Object Camera (NEOCam) proposal, which she’s been working on since 2005. Her group received technology development funding in 2010 to improve their infrared detectors, which succeeded in passing recent tests. Their group will seek more funding for NASA in the next opportunity.
The WISE spacecraft’s NEOWISE mission, meanwhile, is going to restart early next year, Mainzer added. “While NEOWISE is not nearly as capable as NEOCam will be, it will improve our knowledge of the diameters and albedos of about 2,000 NEOs and tens of thousands of main belt asteroids,” Mainzer wrote. “With the NEOWISE prime mission, we discovered more than 34,000 new asteroids and observed >158,000 in total. We have used our data from NEOWISE to set constraints on the number of NEOs and potentially hazardous asteroids.”

Getting the United Nations involved:

This week, the United Nations Committee on the Peaceful Uses of Outer Space adopted several steps related to asteroids. It’s planning an International Asteroid Warning Group (to share detections and warn of potential impacts), an Impact Disaster Planning Advisory Group, and a Space Missions Planning and Advisory Group (which would look at deflection missions, options, costs, etc.)
Why go with the United Nations? In the panel, NASA Apollo astronaut Rusty Schweickart explained it this way: deciding how to deflect an asteroid posts risks. You might be moving the impact path past a country that would not have been at risk before the deflection. It’s best to make such moves internationally, rather than having (say) the United States make a decision that could increase Russia’s risk to an asteroid.
The problem? Working by committee is slow, says former Romanian astronaut Dumitru-Dorin Prunariu: “You would think with the United Nations that we started to think about asteroids only in 2007, 8 or 9, but the first input was done by 1999 at the Unispace conference, the United Nations International Conference in Space.” People have been working hard, to be sure, but making a good, inclusive plan just takes time. An action team was formed in 2001, a working group was in place by 2007, and the adoptions by UNCOPUOS (as we stated earlier) took place this week.

Cost of all of this:

Schweickart: “Money is hardly an issue in this. This is a very inexpensive thing to do. It’s organizational setting the actual criteria, thresholds whatever.” It would only cost 1% of the NASA budget for the next 10 years, and less than 0.5% after that. (The NASA budget request for 2014 was $17.7 billion, so 1% of that is $177 million.)
The panel members emphasized that it’s best to start the search early and find the threatening asteroids before things become an emergency. If a moderate-sized asteroid was discovered only a few months out, it might be better just to evacuate the affected area rather than try to pull together a last-minute mission to stop the asteroid.

Cygnus Commercial Cargo Craft Completes Historic First Flight to Space Station

Commercial space took another major leap forward this morning, Oct 22., when the privately developed Cygnus cargo vehicle undocked from the International Space Station on its historic maiden flight and successfully completed a highly productive month long stay during its demonstration mission – mostly amidst the US government shutdown.

The Cygnus was maneuvered about 10 meters (30 feet) away from the station and held in the steady grip of the stations fully extended robotic arm when astronauts Karen Nyberg and Luca Parmitano unlatched the arm and released the ship into free space at 7:31 a.m. EDT today – signifying an end to joint flight operations.

The next Cygnus resupply vessel is due to blast off in mid-December and is already loaded with new science experiments for microgravity research and assorted gear and provisions.

After the Expedition 37 crew members quickly pulled the arm back to a distance 1.5 meters away from Cygnus, ground controllers issued a planned “abort” command to fire the ships thrusters and safely depart from the massive orbiting lab complex.

“It’s been a great mission. Nice work today!” radioed Houston Mission Control at NASA’s Johnson Space Center.

The vehicles were flying over the Atlantic Ocean and off the east coast of Argentina as Cygnus left the station some 250 miles (400 km) overhead in low Earth orbit.

The event was carried live on NASA TV and Cygnus was seen moving rapidly away.

Barely five minutes later Cygnus was already 200 meters away, appeared very small in the cameras view and exited the imaginary “Keep Out Sphere” – a strictly designated safety zone around the million pound station.

The Cygnus resupply ship delivered about 1,300 pounds (589 kilograms) of cargo, including food, clothing, water, science experiments, spare parts and gear to the six person Expedition 37 crew.

After the crew unloaded all that cargo, they packed the ship with 2,850 pounds of no longer needed trash.

On Wednesday (Oct. 23), a pair of deorbit burns with target Cygnus for a destructive reentry back into the Earth’s atmosphere at 2:18 p.m. EDT, to plummet harmlessly into the Pacific Ocean.

Cygnus was developed by Orbital Sciences Corp. with seed money from NASA in a public-private partnership between NASA and Orbital Sciences under NASA’s COTS commercial transportation initiative.

SpaceX Corp. was also awarded a COTS contract to develop the Dragon cargo carrier so that NASA would have a dual capability to stock up the station.

COTS was aimed at fostering the development of America’s commercial space industry to deliver critical and essential supplies to the ISS following the retirement of the Space Shuttle program.

“Congratulations to the teams at Orbital Sciences and NASA who worked hard to make this demonstration mission to the International Space Station an overwhelming success,” NASA Administrator Charles Bolden said in a statement.

“We are delighted to now have two American companies able to resupply the station. U.S. innovation and inspiration have once again shown their great strength in the design and operation of a new generation of vehicles to carry cargo to our laboratory in space. Orbital’s success today is helping make NASA’s future exploration to farther destinations possible.”

America completely lost its capability to send humans and cargo to the ISS when NASA’s space shuttles were forcibly retired in 2011. Orbital Sciences and SpaceX were awarded NASA contracts worth over $3 Billion to restore the unmanned cargo resupply capability over 20 flights totally.

Cygnus was launched to orbit on its inaugural flight on Sept. 18 atop Orbital’s commercial Antares rocket from NASA’s Wallops Flight Facility on the Eastern shore of Virginia.

The initially planned Sept. 22 berthing of the spacecraft at a port on the Earth facing Harmony node was delayed a week to Sept. 29 due to an easily fixed communications glitch. It was no worse for the wear and performed admirably.

“Antares next flight is scheduled for mid December,” according to Frank Culbertson, former astronaut and now Orbital’s executive Vice President responsible for the Antares and Cygnus programs.

Skeleton Crew gets LADEE in Orbit, Checked Out and Fires Revolutionary Laser During Gov’t Shutdown

NASA’s new LADEE spacecraft successfully entered lunar orbit, is operating beautifully and has begun shooting its radical laser communications experiment despite having to accomplish a series of absolutely critical do-or-die orbital insertion engine firings with a “skeleton crew ” – all this amidst the NASA and US government shutdown, NASA Ames Research Center Director Pete Worden told Universe Today in a LADEE mission exclusive.

During the two and a half week long NASA shutdown, engineers had to fire LADEE’s maneuvering thrusters three times over six days – first to brake into elliptical orbit about the Moon and then lower it significantly and safely into a circular commissioning orbit.

“All burns went super well,” Ames Center Director Worden told me exclusivly. And he is extremely proud of the entire team of “dedicated” professional men and women who made it possible during the shutdown.

“It says a lot about our people’s dedication and capability when a skeleton crew can get a new spacecraft into lunar orbit and fully commissioned in the face of a shutdown!” Worden said to Universe Today.

“I’m really happy that everyone’s back.”

After achieving orbit, a pair of additional engine burns reduced LADEE’s altitude and period into its initial commissioning orbit and teams began the month long activation and instrument checkout phase.

“We are at the commissioning orbit of 250 km,” said Worden.

And to top all that off, LADEE’s quartet of science instruments are checked out and the ground – breaking laser communications experiment that will bring about a quantum leap in transmitting space science data has already begun its work!

“All instruments are fully checked out with covers deployed.”

“We’ve begun the Lunar Laser Communications Demonstration (LLCD) tests and its working very well,” Worden explained.

And that’s the whole point of the LADEE mission in the first place.

97% of NASA’s employees were furloughed during the utterly chaotic and wasteful partial shutdown of the US government that lasted from Oct. 1 to Oct. 17 and also temporarily threatened the upcoming launch of NASA’s next mission to Mars – the MAVEN orbiter.

However, orbital mechanics follows the natural laws of the Universe, continues unabated and waits for no one in Washington, D.C.

NASA’s Jupiter-bound Juno orbiter also flew by Earth amidst the DC shutdown showdown on Oct. 9 for a similarly critical do-or-die gravity assisted speed boost and trajectory targeting maneuver.

The stakes were extremely high for NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) mission because the spacecraft was on course for the Moon and absolutely had to ignite its main engine on the Sunday morning of Oct. 6.

There were no second chances. If anything failed, LADEE would simply sail past the Moon with no hope of returning later.

So, mission controllers at NASA Ames commanded LADEE to ignite its main engine and enter lunar orbit on Oct. 6 following the spectacular Sept. 6 night launch from NASA’s Wallops Island spaceport in Virginia.

The approximately four minute long burn know as Lunar Orbit Insertion burn 1 (LOI-1) began with LADEE’s arrival at the Moon following three and a half long looping orbits of the Earth.

LOI-1 changed the spacecrafts velocity by 329.8 meters/sec so that the couch sized probe could be captured by the Moon’s gravity and be placed into a 24 hour polar elliptical orbit.

The LOI-2 maneuver on Oct. 9 put LADEE into a 4-hour elliptic lunar orbit. The third and final LOI-3 burn occurred on Oct. 12, and put the spacecraft into the 2-hour commissioning orbit (roughly 235 Km x 250 Km), according to a NASA statement.

The 844 pound (383 kg) robot explorer was assembled at NASA’s Ames Research Center, Moffett Field, Calif., and is a cooperative project with NASA Goddard Spaceflight Center in Maryland.

“LADEE is the first NASA mission with a dedicated laser communications experiment,” said Don Cornwell, mission manager for the Lunar Laser Communications Demonstration (LLCD), NASA’s Goddard Space Flight Center, Greenbelt, Md, during an interview with Universe Today at the LADEE launch.

“With the LLCD experiment, we’ll use laser communications to demonstrate at least six times more data rate from the moon than what we can do with a radio system with half the weight and 25 percent less power,” said Cornwell.

The LADEE satellite in lunar orbit. The revolutionary modular science probe is equipped with a Lunar Laser Communication Demonstration (LLCD) that will attempt to show two-way laser communication beyond Earth is possible, expanding the possibility of transmitting huge amounts of data. This new ability could one day allow for 3-D High Definition video transmissions in deep space to become routine. Credit: NASA

The LLCD will be operated for about 30 days during the time of the commissioning orbit period.

The purpose of LADEE is to collect data that will inform scientists in unprecedented detail about the ultra thin lunar atmosphere, environmental influences on lunar dust and conditions near the surface. In turn this will lead to a better understanding of other planetary bodies in our solar system and beyond.

The $280 million probe is built on a revolutionary ‘modular common spacecraft bus’, or body, that could dramatically cut the cost of exploring space and also be utilized on space probes to explore a wide variety of inviting targets in the solar system.

“LADEE is the first in a new class of interplanetary exploration missions,” NASA Ames Director Worden told Universe Today. “It will study the pristine moon to study significant questions.”

“This is probably our last best chance to study the pristine Moon before there is a lot of human activity there changing things.”

India’s First Mars Mission Set to Blast off Seeking Methane Signature

India is gearing up for its first ever space undertaking to the Red Planet – dubbed the Mars Orbiter Mission, or MOM – which is the brainchild of the Indian Space Research Organization, or ISRO.

Among other objectives, MOM will conduct a highly valuable search for potential signatures of Martian methane – which could stem from either living or non living sources. The historic Mars bound probe also serves as a forerunner to bolder robotic exploration goals.

If all goes well 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).

The 1,350 kilogram (2,980 pound) orbiter, also known as ‘Mangalyaan’, is slated to blast off as early as Oct. 28 atop India’s highly reliable Polar Satellite Launch Vehicle (PSLV) from a seaside launch pad in Srihanikota, India.

MOM is outfitted with an array of five 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 biological and geological sources.

ISRO officials are also paying close attention to the local weather to ascertain if remnants from Tropical Cyclone Phaillin or another developing weather system in the South Pacific could impact liftoff plans.

The launch target date will be set following a readiness review on Friday, said ISRO Chairman K. Radhakrishnan according to Indian press reports.

‘Mangalyaan’ is undergoing final prelaunch test and integration at ISRO’s Satish Dhawan Space Centre SHAR, Srihairkota on the east coast of Andhra Pradesh state following shipment from ISRO’s Bangalore assembly facility on Oct. 3.

ISRO has already assembled the more powerful XL extended version of the four stage PSLV launcher at Srihairkota.

MOM’s launch window extends about three weeks until Nov. 19 – which roughly coincides with the opening of the launch window for NASA’s next mission to Mars, the MAVEN orbiter.

The upcoming Nov. 18 blastoff of NASA’s new MAVEN Mars orbiter was threatened by the US Federal Government shutdown when all launch processing work ceased on Oct. 1. Spacecraft preps had now resumed on Oct. 3 after receiving an emergency exemption.

MAVEN’s on time blastoff from Florida on Nov. 18, had been threatened by the chaos caused by the partial US government shutdown that finally ended this morning (Oct. 17), until the mission was granted an ‘emergency exemption’ due to the critical role it will play in relaying data from NASA’s ongoing pair of surface rovers – Curiosity and Opportunity.

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).

As India’s initial mission to Mars, ISRO says that the mission’s objectives are both technological and scientific to demonstrate the nation’s capability to design an interplanetary mission and carry out fundamental Red Planet research with a suite of indigenously built instruments.

MOM’s science complement comprises includes the tri color Mars Color Camera to image the planet and its two moon, Phobos and Diemos; 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.

It will be of extremely great interest to compare any methane detection measurements from MOM to those ongoing from NASA’s Curiosity rover – which found ground level methane to be essentially nonexistent – and Europe’s planned 2016 ExoMars Trace Gas Orbiter.

MOM’s design builds on spacecraft heritage from India’s Chandrayaan 1 lunar mission that investigated the Moon from 2008 to 2009.

The 44 meter (144 ft) PSLV will launch MOM into an initially elliptical Earth parking orbit of 248 km x 23,000 km. A series of six orbit raising burns will eventually dispatch MOM on a trajectory to Mars by late November, assuming an Oct. 28 liftoff.

Following a 300 day interplanetary cruise phase, the do or die orbital insertion engine will fire on September 14, 2014 and place MOM into an 377 km x 80,000 km elliptical orbit.

NASA’s MAVEN is also due to arrive in Mars orbit during September 2014.

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

Engineers have deftly managed to successfully restore NASA’s Jupiter-bound Juno probe back to full operation following an unexpected glitch that placed the ship into ‘safe mode’ during the speed boosting swing-by of Earth on Wednesday, Oct. 9 – the mission’s top scientist told Universe Today late Friday.

“Juno came out of safe mode today!” Juno principal investigator Scott Bolton happily told me Friday evening. Bolton is from the Southwest Research Institute (SwRI), San Antonio, Texas.

The solar powered Juno spacecraft conducted a crucial slingshot maneuver by Earth on Wednesday that accelerated its velocity by 16,330 mph (26,280 km/h) thereby enabling it to be captured into polar orbit about Jupiter on July 4, 2016.

“The safe mode did not impact the spacecraft’s trajectory one smidgeon!”

Juno exited safe mode at 5:12 p.m. ET Friday, according to a statement from the Southwest Research Institute. Safe mode is a designated fault protective state that is preprogrammed into spacecraft software in case something goes amiss.

“The spacecraft is currently operating nominally and all systems are fully functional,” said the SwRI statement.

Although the Earth flyby did accomplish its primary goal of precisely targeting Juno towards Jupiter – within 2 kilometers of the aim point ! – the ship also suffered an unexplained anomaly that placed Juno into ‘safe mode’ at some point during the swoop past Earth.

“After Juno passed the period of Earth flyby closest approach at 12:21 PM PST [3:21 PM EDT] and we established communications 25 minutes later, we were in safe mode,” Juno Project manager Rick Nybakken, told me in a phone interview soon after Wednesday’s flyby of Earth. Nybakken is from NASA’s Jet Propulsion Lab in Pasadena, CA.

Nybakken also said that the probe was “power positive and we have full command ability.”

So the mission operations teams at JPL and prime contractor Lockheed Martin were optimistic about resolving the safe mode issue right from the outset.

“The spacecraft acted as expected during the transition into and while in safe mode,” acording to SwRI.

During the flyby, the science team also planned to observe Earth using most of Juno’s nine science instruments since the slingshot also serves as an important dress rehearsal and key test of the spacecraft’s instruments, systems and flight operations teams.

“The Juno science team is continuing to analyze data acquired by the spacecraft’s science instruments during the flyby. Most data and images were downlinked prior to the safe mode event.”

Juno’s closest approach took place over the ocean just off the tip of South Africa at about 561 kilometers (349 miles).

Juno launched atop an Atlas V rocket two years ago from Cape Canaveral Air Force Station, FL, on Aug. 5, 2011 on a journey to discover the genesis of Jupiter hidden deep inside the planet’s interior.

The $1.1 Billion Juno probe is continuing on its 2.8 Billion kilometer (1.7 Billion mile) outbound trek to the Jovian system.

During a one year long science mission – entailing 33 orbits lasting 11 days each – the probe will plunge to within about 3000 miles of the turbulent cloud tops and collect unprecedented new data that will unveil the hidden inner secrets of Jupiter’s origin and evolution.

NASA’s Juno Spacecraft Returns 1st Flyby images of Earth while Sailing On to Jupiter

Following the speed boosting slingshot of Earth on Wednesday, Oct. 9, that sent NASA’s Juno orbiter hurtling towards Jupiter, the probe has successfully transmitted back data and the very first flyby images despite unexpectedly going into ‘safe mode’ during the critical maneuver.

“Juno is transmitting telemetry today,” spokesman Guy Webster, of NASA’s Jet Propulsion Lab (JPL), told me in a phone interview late today (Oct. 10), as Juno continues sailing on its 2.8 Billion kilometer (1.7 Billion mile) outbound trek to the Jovian system.

The new images of Earth captured by the Junocam imager serves as tangible proof that Juno is communicating.

“Juno is still in safe mode today (Oct. 10),” Webster told Universe Today.

“Teams at mission control at JPL and Lockheed Martin are actively working to bring Juno out of safe mode. And that could still require a few days,” Webster explained.

Lockheed Martin is the prime contractor for Juno.

The initial raw images of Earth snapped by the craft’s Junocam imager were received by ground stations late today.

See above a day light image mosaic which I reconstructed and realigned based on the original raw image (see below) taken with the camera’s methane filter on Oct. 9 at 12:06:30 PDT (3:06:30 PM EST). Juno was to be flying over South America and the southern Atlantic Ocean.

Juno performed a crucial swingby of Earth on Wednesday that accelerated the probe by 16330 MPH to enable it to arrive in orbit around Jupiter on July 4, 2016.

However the gravity assist maneuver did not go entirely as planned.

Shortly after Wednesday’s flyby, Juno Project manager Rick Nybakken, of JPL, told me in a phone interview that Juno had entered safe mode but that the probe was “power positive and we have full command ability.”

“After Juno passed the period of Earth flyby closest approach at 12:21 PM PST [3:21 PM EDT] and we established communications 25 minutes later, we were in safe mode,” Nybakken explained.

The safe mode was triggered while Juno was in an eclipse mode, the only eclipse it will experience during its entire mission.

The Earth flyby did accomplish its objective by placing the $1.1 Billion Juno spacecraft exactly on course for Jupiter as intended.

“We are on our way to Jupiter as planned!”

“None of this affected our trajectory or the gravity assist maneuver – which is what the Earth flyby is,” Nybakken stated.

Juno’s closest approach was over South Africa at about 561 kilometers (349 miles).

During the flyby, the science team also planned to observe Earth using most of Juno’s nine science instruments since the slingshot also serves as a key test of the spacecraft systems and the flight operations teams.

Juno also was to capture an unprecedented new movie of the Earth/Moon system.

Many more images were snapped and should be transmitted in coming days that eventually will show a beautiful view of the Earth and Moon from space.

“During the earth flyby we have most of our instruments on and will obtain a unique movie of the Earth Moon system on our approach, Juno principal investigator Scott Bolton told me. Bolton is from the Southwest Research Institute (SwRI), San Antonio, Texas.

“We will also calibrate instuments and measure earth’s magnetosphere, obtain closeup images of the Earth and the Moon in UV [ultraviolet] and IR [infrared],” Bolton explained to Universe Today.

Juno is approaching the Earth from deep space, from the sunlit side.

“Juno will take never-before-seen images of the Earth-moon system, giving us a chance to see what we look like from Mars or Jupiter’” says Bolton.

Here is a description of Junocam from the developer – Malin Space Science Systems

“Like previous MSSS cameras (e.g., Mars Reconnaissance Orbiter’s Mars Color Imager) Junocam is a “pushframe” imager. The detector has multiple filter strips, each with a different bandpass, bonded directly to its photoactive surface. Each strip extends the entire width of the detector, but only a fraction of its height; Junocam’s filter strips are 1600 pixels wide and about 155 rows high. The filter strips are scanned across the target by spacecraft rotation. At the nominal spin rate of 2 RPM, frames are acquired about every 400 milliseconds. Junocam has four filters: three visible (red/green/blue) and a narrowband “methane” filter centered at about 890 nm.”

Mercury Astronaut Scott Carpenter Dies

One of the original “Mercury 7” astronauts, Scott Carpenter, has died. He was the sixth person to fly in space; the fourth American to fly in space and the second US astronaut to orbit Earth. Carpenter died on Thursday, October 10, 2013 at age 88 after suffering a recent stroke. With the death of Carpenter, the only remaining surviving member of the original US astronauts is John Glenn.

collectSPACE is reporting that Carpenter was being cared for at a hospice center in Denver when he passed. Carpenter was initially expected to make a full recovery from the stroke, but his condition worsened this week, sources close to his family shared.

Carpenter was chosen as an astronaut in 1959. He launched in his Aurora 7 capsule on May 24, 1962 in the fourth manned mission and the second orbital flight of the Mercury program. The video below celebrates the Aurora 7 flight, which successfully made three Earth orbits. But a targeting mishap during reentry took the spacecraft about 400 km (250 miles) off course, delaying recovery of Carpenter and the capsule. Carpenter was picked up after nearly 3 hours in the water, and the Mercury capsule was not retrieved until about 6 hours later.

Carpenter said of his flight, “The zero-g sensation and the visual sensation of space flight are transcending experiences, and I wish everybody could have them.”

Carpenter was born on n May 1, 1925. He is survived by his wife, seven children, two step-children and six grandchildren.
