In less than 48 hours, Russia’s bold Phobos-Grunt mechanized probe will embark on a historic flight to haul humanities first ever soil samples back from the tiny Martian moon Phobos. Liftoff from the Baikonur Cosmodrome remains on target for November 9 (Nov 8 US 3:16 p.m. EDT).

For an exquisite view of every step of this first-of-its-kind robot retriever, watch this spectacular action packed animation (below) outlining the entire 3 year round trip voyage. The simulation was produced by Roscosmos, Russia’s Federal Space Agency and the famous IKI Space Research Institute. It’s set to cool music – so don’t’ worry, you don’t need to understand Russian.

Another video below shows the arrival and uncrating of the actual Phobos-Grunt spacecraft at Baikonur in October 2011.

The highly detailed animation begins with the blastoff of the Zenit booster rocket and swiftly progresses through Earth orbit departure, Phobos-Grunt Mars orbit insertion, deployment of the piggybacked Yinghuo-1 (YH-1) mini satellite from China, Phobos-Grunt scientific reconnaissance of Phobos and search for a safe landing site, radar guided propulsive landing, robotic arm manipulation and soil sample collection and analysis, sample transfer to the Earth return capsule and departure, plummeting through Earth’s atmosphere and Russian helicopter retrieval of the precious cargo carrier.

Only time now stands in the way of Curiosity’s long awaited date with the Red Planet. NASA’s next, and perhaps last Mars rover was transported to the launch pad at Cape Canaveral Air Force Station and then hoisted on top of the mighty Atlas V rocket that will propel her on a 10 month interplanetary journey to Mars to seek out the potential habitats of Extraterrestrial life.

In less than three weeks on November 25 – the day after Thanksgiving – the Curiosity Mars Science Laboratory (MSL) rover will soar to space aboard the Atlas V booster. Touchdown astride a layered mountain at the Gale Crater landing site is set for August 2012.

The $2.5 Billion rover must liftoff by Dec. 18 at the latest, when the launch window to Mars closes for another 26 months. Any delay would cost hundreds of millions of dollars.

Curiosity represents a quantum leap in science capabilities and is by far the most advanced robotic emissary sent to the surface of another celestial body. MSL will operate for a minimum of one Martian year, equivalent to 687 days on earth.

After years of meticulous design work and robotic construction by dedicated scientists and engineers at NASA’s Jet Propulsion Laboratory in California and months of vigilant final assembly and preflight processing at the Payload Hazardous Servicing Facility (PHSF) at NASA’s Kennedy Space Center in Florida, Curiosity was finally moved the last few miles (km) she’ll ever travel on Earth – in the dead of night – to Space Launch Complex 41 at the Cape.

The robo behemoth was tucked inside her protective aeroshell Mars entry capsule and clamshell-like nose cone, gingerly loaded onto the payload transporter inside the PHSF and arrived – after a careful drive – at Pad 41 at about 4:35 a.m. EDT on Nov. 3. The move was delayed one day by high winds at the Cape.

Teams from rocket builder United Launch Alliance then hoisted MSL by crane on top of the Atlas V rocket already assembled inside the launch gantry known as the Vertical Integration Facility, or VIF, and bolted it to the venerable Centaur upper stage. Technicians also attached umbilicals for mechanical, electrical and gaseous connections.

Curiosity’s purpose is to search for evidence of habitats that could ever have supported microbial life on Mars and determine whether the ingredients of life exist on Mars today in the form of organic molecules – the building blocks of life.

We are all made of organic molecules – which is one of the essential requirements for the genesis of life along with water and an energy source. Mars harbors lots of water and is replete with energy sources, but confirmation of organics is what’s lacking.

The Atlas V will launch in the configuration known as Atlas 541. The 4 indicates a total of four solid rocket motors (SRM) are attached to the base of the first stage. The 5 indicates a five meter diameter payload fairing. The 1 indicates use of a single engine Centaur upper stage.

One of the last but critical jobs remaining at the pad is installation of Curiosity’s MMRTG (Multi-Mission Radioisotope Thermoelectric Generator) power source about a week before launch around Nov. 17. Technicians will install the MMRTG through small portholes on the side of the payload fairing and aeroshell.

The nuclear power source will significantly enhance the driving range, scientific capability and working lifetime of the six wheeled rover compared to other solar powered landed surface explorers like Pathfinder, Spirit, Opportunity, Phoenix and Phobos-Grunt.

The minivan sized rover measures three meters in length, roughly twice the size of the MER rovers; Spirit and Opportunity. MSL is equipped with 10 science instruments for a minimum two year expedition across Gale crater. The science payload weighs ten times more than any prior Mars rover mission.

The Atlas V rocket and Curiosity will roll out to the launch pad on Wednedsay, November 23, the day before Thanksgiving.

Meanwhile, Russia’s Phobos-Grunt mission to Mars and Phobos is on target to blast off on November 9, Moscow time [Nov 8, US time].

No Alien Visits or UFO Coverups, White House Says

[/caption]

The White House has responded to two petitions asking the US government to formally acknowledge that aliens have visited Earth and to disclose to any intentional withholding of government interactions with extraterrestrial beings. “The U.S. government has no evidence that any life exists outside our planet, or that an extraterrestrial presence has contacted or engaged any member of the human race,” said Phil Larson from the White House Office of Science & Technology Policy, on the WhiteHouse.gov website. “In addition, there is no credible information to suggest that any evidence is being hidden from the public’s eye.”

5,387 people had signed the petition for immediately disclosing the government’s knowledge of and communications with extraterrestrial beings, and 12,078 signed the request for a formal acknowledgement from the White House that extraterrestrials have been engaging the human race.

“Hundreds of military and government agency witnesses have come forward with testimony confirming this extraterrestrial presence,” the second petition states. “Opinion polls now indicate more than 50% of the American people believe there is an extraterrestrial presence and more than 80% believe the government is not telling the truth about this phenomenon. The people have a right to know. The people can handle the truth.”

These petitions come from an Obama Administration initiative called ‘We the People’ which has White House staffers respond and consider taking action on any issue that receives at least 25,000 online signatures. Regarding these two petitions, the White House promised to respond if the petitions got 17,000 or more signatures by Oct. 22.

Larson stressed that the facts show that there is no credible evidence of extraterrestrial presence here on Earth. He pointed out that even though many scientists have come to the conclusion that the odds of life somewhere else in the Universe are fairly high, the chance that any of them are making contact with humans are extremely small, given the distances involved.

But that doesn’t mean we aren’t searching, there is just no evidence yet. Larson mentioned SETI (correctly noting that this at first was a NASA effort, but is now funded privately) keeping an “ear” out for signals from any intelligent extraterrestrials, with none found so far. He also added that the Kepler spacecraft is searching for Earth-like planets in the habitable zones around other stars, and that the Curiosity rover will launch to Mars this month to “assess what the Martian environment was like in the past to see if it could have harbored life.”

Regarding any evidence for alien life, all anyone has now is “statistics and speculation,” said Larson. “The fact is we have no credible evidence of extraterrestrial presence here on Earth.”

Whether or not this will appease or satisfy any conspiracy theorists or UFO believers is yet to be seen, but it is gratifying to see the White House respond in such a no-nonsense manner.

UPDATE: The Paradigm Research Group, one of the organizations sponsoring the petitions, has issued a statement saying, “As expected it was written by a low level staffer from the Office of Science and Technology Policy – research assistant Phil Larson. The response was unacceptable.”

See the petitions and the response at the WhiteHouse.gov website.

[/caption]

Phobo-Grunt, Russia’s first interplanetary mission in nearly two decades, has now been encapsulated inside the payload fairing and sealed to the payload adapter for mating to the upper stage of the Zenit booster rocket that will propel the probe to Mars orbit and carry out history’s first ever landing on the petite Martian moon Phobos and eventually return pristine samples to Earth for high powered scientific analysis.

“Phobos-Grunt will launch on November 9, 2011 at 00:16 a.m. Moscow time [Nov. 8 3:16 p.m. EST],” said Alexey Kuznetsov, Head of the Roscosmos Press Office in an exclusive interview with Universe Today. Roscosmos is the Russian Federal Space Agency, equivalent to NASA and ESA.

“The launch window extends until November 25.”

“At this moment we are preparing the “Zenit-2SB” launch vehicle, the cruise propulsion system and the “Phobos Grunt” automatic interplanetary station at the Baikonur Cosmodrome,” Kuznetzov told me. Phobos-Grunt translates as Phobos-Soil.

China’s first ever mission to Mars, the Yinghuo-1 micro-satellite, is also encased inside the nose cone and is tucked in a truss segment between the lander and interplanetary propulsion stage.

Yinghuo-1 follows closely on the heels of China’s stunning success in demonstrating the nation’s first ever docking in space between two Chinese spacecraft earlier this week on November 3.

The payload fairing protects the Phobos-Grunt and Yinghuo-1 spacecraft during the first few minutes of flight from the intense frictional heating and buildup of aerodynamic pressures. After the rocket soars through the discernable atmosphere the fairing splits in half and is jettisoned and falls back to Earth.

The nose cone sports a beautiful mission logo painted on the side of the fairing along with the logos of various Russian and International partner agencies and science institutes.

Propellants have already been loaded aboard the cruise stage, Phobos-Grunt lander and Earth return vehicle.

“The Phobos Grunt automatic interplanetary station was built, prepared and tested at NPO Lavochkin [near Moscow]. They were also responsible for inspection of the devices, instruments and systems integration,” Kuzntezov explained.

“Significant improvements and modifications and been made to both the “Fregat-SB” upper stage and the “Zenit-2SB” rocket,” said Kuznetzov.

Phobos-Grunt will blastoff from Launch Pad 45 at Baikonur,

Following an 11 month journey, the spaceship will enter Mars orbit in October 2012, spend several months investigating Phobos and then land around February 2013.

The goal is to snatch up to 200 grams of soil and rock from Phobos and fly them back to Earth in a small capsule set to plummet through the atmosphere in August 2014.

ESA, the European Space Agency, is assisting Russia determine a safe landing site by targeting their Mars Express Orbiter to collect high resolution images of Phobos. Look at 2 D and 3 D images and an animation here.

The regolith samples will help teach volumes about the origin and evolution of Phobos, Mars and the Solar System. Scientists would be delighted if miniscule bits of Martian soil were mixed in with Phobos soil.

Phobos-Grunt , Earth’s next mission to Mars, is equipped with an advanced 50 kg payload array of some 20 science instruments.

NASA’s Curiosity Mars rover was also enclosed in her payload fairing a few days ago and is on course for liftoff on November 25.

The Phobos-Grunt spacecraft is scheduled to blastoff on November 9, 2011 from Baikonur Cosmodrome. It will reach Mars orbit in 2012 and eventually land on Phobos and return the first ever soil samples back to Earth in 2014. Credit Roscosmos

In just 7 days, Russia’s Phobos-Grunt sample return mission will blast off for Mars on November 9 on a daring mission to grab soil samples from the surface of the miniscule martian moon Phobos and return them back to Earth for analysis to give us breathtaking new insights into the formation and evolution of Mars, Phobos and our Solar System.

So, check out the amazing animation and 3 D stereo images of fish-like Phobos and banded Jupiter snapped by Europe’s Mars Express orbiter to get a bird’s eye feel for the battered terrain, inherent risks and outright beauty that’s in store for the Phobos -Grunt spaceship when it arrives in the Red Planet’s vicinity around October 2012. Whip out your red-cyan 3 D glasses – Now !

ESA’s Mars Express orbiter (MEX) was tasked to help Russia locate suitable and safe landing sites on Phobos’ pockmarked terrain. MEX was built by ESA, the European Space Agency and has been in Mars orbit since 2003.

To capture this impressive series of rare photos of Jupiter and Phobos in conjunction, Mars Express performed a special maneuver to observe an unusual alignment of Jupiter and Phobos on 1 June 2011.

Mars Express High Resolution Stereo Camera (HRSC) snapped a total of 104 images over 68 seconds when the distance from the spacecraft to Phobos was 11,389 km and the distance to Jupiter was 529 million km.

Closing the Clamshell on a Martian Curiosity

In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, sections of an Atlas V rocket payload fairing engulf NASA's Mars Science Laboratory (MSL) as they close in around it. The blocks on the interior of the fairing are components of the fairing acoustic protection (FAP) system, designed to protect the payload by dampening the sound created by the rocket during liftoff. Launch of MSL aboard a United Launch Alliance Atlas V rocket is planned for Nov. 25 from Space Launch Complex-41 on Cape Canaveral Air Force Station. Credit: NASA/Jim Grossmann

Curiosity’s clamshell has been closed.

And it won’t open up again until a few minutes after she blasts off for the Red Planet in just a little more than 3 weeks from now on Nov. 25, 2011 – the day after Thanksgiving celebrations in America.

The two halves of the payload fairing serve to protect NASA’s next Mars rover during the thunderous ascent through Earth’s atmosphere atop the powerful Atlas V booster rocket that will propel her on a fantastic voyage of hundreds of millions of miles through interplanetary space.

Spacecraft technicians working inside the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center (KSC) in Florida have now sealed Curiosity and her aeroshell inside the payload fairing shroud. The fairing insulates the car sized robot from the intense impact of aerodynamic pressure and heating during ascent. At just the right moment it will peal open and be jettisoned like excess baggage after the rocket punches through the discernable atmosphere.

“Curiosity will be placed onto the payload transporter on Tuesday and goes to Complex 41 on Wednesday, Nov. 2,” KSC spokesman George Diller told Universe Today. “The logo was applied to the fairing this weekend.”

At Pad 41, the payload will then be hoisted atop the United Launch Alliance Atlas V rocket and be bolted to the Centaur upper stage.

Installation of Curiosity’s MMRTG (Multi-Mission Radioisotope Thermoelectric Generator) power source is one of the very last jobs and occurs at the pad just in the very final days before liftoff for Mars.

The MMRTG will be installed through a small porthole in the payload fairing and the aeroshell (see photo below).

The plutonium dioxide based power source has more than 40 years of heritage in interplanetary exploration and will significantly enhance the driving range, scientific capability and working lifetime of the six wheeled rover compared to the solar powered rovers Spirit and Opportunity.

After a 10 month voyage, Curiosity is due to land at Gale Crater in August 2012 using the revolutionary sky crane powered descent vehicle for the first time on Mars.

Curiosity has 10 science instruments to search for evidence about whether Mars has had environments favorable for microbial life, including chemical ingredients for life. The unique rover will use a laser to look inside rocks and release the gasses so that its spectrometer can analyze and send the data back to Earth.

Take a good last, long look at the magnificent robot that is Curiosity, because she’s been all buttoned up for her long Martian voyage in search of the ingredients of life. After years of exhaustive work, the most technologically advanced surface robotic rover ever to be sent beyond Earth has been assembled into the flight configuration, a NASA spokesperson informed Universe Today.

The next time Curiosity opens her eyes she will have touched down at the foot of a layered mountain inside the planet’s Gale crater.

Curiosity – NASA’s next Mars rover – is formally known as the Mars Science Laboratory (or MSL) and has entered the final stages of preflight processing.

After extensive quality assurance testing, Curiosity has been encapsulated for the final time inside the aeroshell that will be her home during the 10 month long interplanetary cruise to Mars. Furthermore, she’s been attached to the cruise stage that will guide her along the path from the home planet to the red planet.

The work to combine all the components into an integrated assembly was carried out inside the clean room facilities of the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center (KSC) in Florida.

The aeroshell is comprised of the heat shield and back shell.

The job of the aeroshell is to protect Curiosity from the intense heat of several thousand degrees F(C) generated by friction as the delicate assemblage smashes into the Martian atmosphere at about 13,200 MPH (5900 m/s) and plummets some 81 miles during the terrifying seven minute long entry, descent and landing (EDL) on the surface.

See Video animation below

The massive 2000 lb (900 kg) rover is folded up and mated to the back shell powered descent vehicle, known as the PDV or Sky Crane. The spacecraft is designed to steer itself through a series of S-curve maneuvers to slow the spacecraft’s descent through the Martian atmosphere.

In the final moments, the rocket powered Sky crane will lower the robot on tethers and then safely set Curiosity down onto the ground at a precise location inside the chosen landing site astride a layered mountain in Gale Crater believed to contain phyllosilicate clays and hydrated sulfate minerals that formed in liquid water.

The robot is the size of a compact car and measures three meters in length, roughly twice the size of the MER rovers; Spirit and Opportunity. It is equipped with 10 science instruments for a minimum two year expedition across Gale crater.

Curiosity will search for the ingredients of life including water and organic molecules and environmental conditions that could have been hospitable to sustaining Martian microbial life forms if they ever existed in the past or survived to the present through dramatic alterations in Mars climatic and geologic history.

Liftoff of the $2.5 Billion Curiosity rover is slated for Nov. 25 from Cape Canaveral Air Force Station in Florida on a United Launch Alliance Atlas V booster rocket. The launch window to Mars extends until Dec. 18.

This coming week, Curiosity will be encapsulated into the clamshell like payload fairing and the MSL logo will then be applied to the fairing, KSC spokesman George Diller told Universe Today. It will then be hoisted onto the payload transporter and carefully conveyed to Space Launch Complex 41 on Nov. 2, for mating atop the Atlas V rocket.

The Atlas V configuration for Curiosity is similar to the one used for Juno except that it employs one less solid rocket motor in a designation known as Atlas 541.

4 indicates a total of four solid rocket motors are attached to the base of the first stage vs. five solids for Juno. 5 indicates a five meter diameter payload fairing. 1 indicates use of a single engine Centaur upper stage.

Blastoff of Curiosity remains on schedule for Nov. 25, 2011, the day after the Thanksgiving holiday in the U.S. The launch window for a favorable orbital alignment to Mars remains open until Dec. 18 after which the mission would face a 26 month delay at a cost likely to be in the hundreds of millions of dollars.

Curiosity is set to touchdown on Mars at Gale Crater between August 6 & August 20, 2012. The compact car sized rover is equipped with 10 science instruments that will search for signs of habitats that could potentially support martian microbial life, past or present if it ever existed.

With just over 6 weeks to go until the liftoff of Curiosity – NASA’s next Mars rover – prelaunch processing at the Kennedy Space Center (KSC) in Florida is rapidly entering the home stretch. Technicians placed the folded rover inside the complete aeroshell to match the Martian entry configuration components together and conduct preflight testing of the integrated assembly at the Payload Hazardous Servicing Facility at KSC. The aeroshell is comprised of the heat shield and back shell and encapsulates Curiosity during the long voyage to Mars.

The job of the aeroshell is to protect the Curiosity Mars Science Laboratory (MSL) from the intense heat of several thousand degrees F(C) generated by friction as the delicate assemblage smashes into the Martian atmosphere during the terrifying entry and descent to the surface.

The rover itself has been mated to the back shell powered descent vehicle, known as the PDV or sky crane. The rocket powered descent stage (PDV) is designed to maneuver through the Martian atmosphere, slow the descent and safely set Curiosity down onto the surface at a precise location inside the chosen landing site of Gale Crater.

Technicians still have several more weeks of hardware testing and planetary protection checks ahead before NASA’s minivan sized Martian robot is encapsulated inside the aeroshell for the final time.

Rotating Curiosity's Back Shell Powered Descent Vehicle
At the Payload Hazardous Servicing Facility at the Kennedy Space Center in Florida, the "back shell powered descent vehicle" configuration of NASA's Mars Science Laboratory is being rotated for final closeout actions. At this time Curiosity and its rocket-powered descent stage have already been integrated, and are now encapsulated inside the spacecraft's back shell. The configuration of rover integrated with the descent stage is the "powered descent vehicle." The back shell, a protective cover, carries the parachute and several other components used during descent. The yellow disks visible at the top of the configuration are the descent stage's radar antennas that will be used to calculate the rover's descent speed and altitude. Credit: NASA/JPL-Caltech

Another major task still to be completed is mating the aeroshell to the cruise stage and then fueling of the cruise stage, which guides MSL from the Earth to Mars, according to Guy Webster, press spokesman for NASA’s Jet Propulsion Laboratory which manages the MSL project for NASA.

The launch of the $2.5 Billion Curiosity rover atop an Atlas V rocket is slated for Nov. 25, the day after Thanksgiving, and the launch window extends until Dec. 18. Arrival at Gale crater is set for August 2012.

Curiosity is by far the most scientifically advanced surface robotic rover ever sent beyond Earth and will search for environmental conditions that could have been favorable to support Martian microbial life forms if they ever existed in the past or present.

Mars Science Lab Rover Will Land in Gale Crater

It’s official: the Mars Science Laboratory rover, Curiosity, will be landing Gale Crater on Mars. Scientists announced the final decision at a special event at the Smithsonian’s National Air and Space Museum Friday morning. Comparing the terrain to an enticing bowl of layered Neopolitan ice cream, the science team announced the rover will land at the foot of a layered mountain inside Gale Crater.

“The science at Gale is going to be amazing and it will be a beautiful place to visit,” said Dawn Sumner, a geologist with the MSL team.

MSL is scheduled to launch in November 2011 from NASA’s Kennedy Space Center in Florida and land in August 2012. Curiosity is twice as long and more than five times as heavy as previous the Mars Exploration rovers Spirit and Opportunity. The rover will study whether the landing region at Gale crater had favorable environmental conditions for supporting microbial life and for preserving clues about whether life ever existed.

News had leaked out a few weeks ago that Gale was the favored site, but scientists today explained what made Gale stand out among the four final candidates, which each offered their own delicious “flavor,” making the decision a difficult one.

“When it comes down to four landing sites, it comes down to what feels right,” said John Grotzinger, Mars Science Laboratory project scientist. “We as a science team, as a community, we got together and in the end we picked the one that felt best. Why? Here, we’ve got mountain of rocks, taller than Mount Whitney. It looks like Hawaii; it’s not a tall spire, but a broad mound. So we can actually climb up this mountain with the rover. That alone justifies sending the spacecraft there. It turns out, though, the most attractive science sites are at the base of the mountain. We can address the principle goals of the things the Mars community would like answers to.”

NASA’s strategy for Mars has been to “follow the water,” since we know that wherever there is water on Earth, there is life. Scientists are hedging their bets on Mars that wherever liquid water once flowed would be the best places to look for evidence of past habitability.

Gale has that going for it.

The portion of the crater where Curiosity will land has an alluvial fan likely formed by water-carried sediments. The layers at the base of the mountain contain clays and sulfates, both known to form in water.

“It’s a huge crater sitting in a very low-elevation position on Mars, and we all know that water runs downhill,” Grotzinger said. “In terms of the total vertical profile exposed and the low elevation, Gale offers attractions similar to Mars’ famous Valles Marineris, the largest canyon in the solar system.”

The scientists emphasized that MSL is not a life detection mission, as it can’t look for fossils. But it can detect organic carbon, which can tell the early environmental story of Mars, found in the sediments within rocks.

Gale Crater crater spans 154 kilometers (96 miles) in diameter and is about the combined area of Connecticut and Rhode Island. The mound in the center rises 5 km (3 miles) height and the Layering in the mound suggests it is the surviving remnant of an extensive sequence of deposits.

The crater is named for Australian astronomer Walter F. Gale.

About the size of a Mini-Cooper, Curiosity has 17 cameras and a full color video camera. The mission should offer incredible vistas that will likely wow the public, beginning with the landing, as Curiosity will take a full color, high definition movie as it descends on the “Sky Crane” landing system.

Anyone else ready for this mission to get going?
