This past Saturday, an Atlas V carrying NASA’s MSL Curiosity Mars rover thundered off the launch pad on the way to Mars. Ever wondered what the rocket launch is like from the roof of the massive VAB (Vehicle Assembly Building) at NASA’s Kennedy Space Center? Videographer David Gonzales shot the launch for Universe Today using 3 different high definition cameras and recorded audio using a high definition audio device.
During ignition you can see white steam stream out the flame trench followed by the darker exhaust as the Solid Rocket Boosters come to life. The Atlas V lifts off on a pillar of bright orange fire leaving behind a white trail of smoke and an artificial cloud of condensed water droplets. Man-made thunder fills the air as Curiosity takes the first step on the journey to Mars.
It’s time to put on your 3-D glasses and go soaring all over the giant asteroid Vesta – thanks to the superlative efforts of Dawn’s international science team.
Now you can enjoy vivid ‘Vestan Vistas’ like you’ve never ever seen before in a vibrant 3 D video newly created by Dawn team member Ralf Jaumann, of the German Aerospace Center (DLR) in Berlin, Germany – see below.
To fully appreciate the rough and tumble of the totally foreign and matchless world that is Vesta, you’ll absolutely have to haul out your trusty red-cyan (or red-blue) 3 D anaglyph glasses.
Then hold on, as you glide along for a global gaze of mysteriously gorgeous equatorial groves ground out by a gargantuan gong, eons ago.
Along the way you’ll see an alien ‘Snowman’ and the remnants of the missing South Pole, including the impressive Rheasilvia impact basin – named after a Vestal virgin – and the massive mountain some 16 miles (25 kilometers) high, or more than twice the height of Mt. Everest.

“If you want to know what it’s like to explore a new world like Vesta, this new video gives everyone a chance to see it for themselves,” Jaumann said. “Scientists are poring over these images to learn more about how the craters, hills, grooves and troughs we see were created.”
NASA’s Dawn spacecraft is humanity’s first probe to investigate Vesta, the second most massive body in the main Asteroid Belt between Mars and Jupiter.

Indeed Dawn was just honored by Popular Science magazine and recognized as one of three NASA Planetary Science missions to earn a ‘Best of What’s New in 2011’ for innovation in the aviation and space category – along with the Curiosity Mars Science Laboratory (MSL) and MESSENGER Mercury orbiter.
The images in the 3 D video were snapped between July and August 2011 as Dawn completed the final approach to Vesta, achieved orbit in July 2011 and circled overhead during the mission’s initial survey orbit phase at an altitude of about 1,700 miles (2,700 kilometers) in August.
How was the 3 D movie created?
“The Dawn team consists of a bunch of talented people. One of those talented people is Ralf Jaumann, Dawn co-Investigator from the DLR in Berlin,” Prof. Chris Russell, Dawn Principal Investigator, of UCLA, told Universe Today.
“Jaumann and the team behind him have stitched together the mosaics we see and they have made shape models of the surface. They are also skilled communicators and have been heroes in getting the Dawn Image of the Day together. I owe them much thanks and recognition for their efforts.”
“They wanted to make and release to the public an anaglyph of the rotating Vesta to share with everyone the virtual thrill of flying over this alien world.”
“I hope everyone who follows the progress of Dawn will enjoy this movie as much as I do.”
“It is just amazing to an old-time space explorer as myself that we can now make planetary exploration so accessible to people all over our globe in their own homes and so soon after we have received the images,” Russell told me.
Dawn is now spiraling down to her lowest mapping orbit known as LAMO (Low Altitude Mapping Orbit), barely 130 miles (210 kilometers) above Vesta’s surface.
“Dawn remains on course and on schedule to begin its scientific observations in LAMO on December 12,” says Dr. Marc Rayman, Dawn’s Chief Engineer from the Jet Propulsion Lab (JPL), Pasadena, Calif.
“The focus of LAMO investigations will be on making a census of the atomic constituents with its gamma ray and neutron sensors and on mapping the gravity field in order to determine the interior structure of this protoplanet.”
“Today, Dawn is at about 245 km altitude,” Rayman told Universe Today.
The 3 D video is narrated by Carol Raymond, Dawn’s deputy principal investigator at JPL.
“Dawn’s data thus far have revealed the rugged topography and complex textures of the surface of Vesta, as can be seen in this video”.
“Soon, we’ll add other pieces of the puzzle such as the chemical composition, interior structure, and geologic age to be able to write the history of this remnant protoplanet and its place in the early solar system.”

A trio of NASA’s Planetary Science mission’s – Mars Science Laboratory (MSL), Dawn and MESSENGER – has been honored by Popular Science magazine and selected as ‘Best of What’s New’ in innovation in 2011 in the aviation and space category.
The Curiosity Mars Science Laboratory was just launched to the Red Planet on Saturday, Nov. 26 and will search for signs of life while traversing around layered terrain at Gale Crater. Dawn just arrived in orbit around Asteroid Vesta in July 2011. MESSENGER achieved orbit around Planet Mercury in March 2011.
Several of the top mission scientists and engineers provided exclusive comments about the Popular Science recognitions to Universe Today – below.
“Of course we are all very pleased by this selection,” Prof. Chris Russell, Dawn Principal Investigator, of UCLA, told Universe Today.
Dawn is the first mission ever to specifically investigate the main Asteroid Belt between Mars and Jupiter and will orbit both Vesta and Ceres – a feat enabled solely thanks to the revolutionary ion propulsion system.
“At the same time I must admit we are also not humble about it. Dawn is truly an amazing mission. A low cost mission, using NASA’s advanced technology to enormous scientific advantage. It is really, really a great mission,” Russell told me.
Vesta is the second most massive asteroid and Dawn’s discoveries of a surprisingly dichotomous and battered world has vastly exceeded the team’s expectations.
“Dawn is NASA at its best: ambitious, exciting, innovative, and productive,” Dr. Marc Rayman, Dawn’s Chief Engineer from the Jet Propulsion Lab (JPL), Pasadena, Calif., told Universe Today.
“This interplanetary spaceship is exploring uncharted worlds. I’m delighted Popular Science recognizes what a marvelous undertaking this is.”
JPL manages both Dawn and Mars Science Laboratory for NASA’s Science Mission Directorate in Washington, D.C.
Dawn is an international science mission. The partners include the German Aerospace Center (DLR), the Max Planck Institute for Solar System Research, the Italian Space Agency and the Italian National Astrophysical Institute.
“Very cool!”, John Grotzinger, the Mars Science Laboratory Project Scientist of the California Institute of Technology, told Universe Today.
“MSL packs the most bang for the buck yet sent to Mars.”
Curiosity is using an unprecedented precision landing system to touch down inside the 154 km (96 miile) wide Gale Crater on Aug. 6, 2012. The crater exhibits exposures of phyllosilicates and other minerals that may have preserved evidence of ancient or extant Martian life and is dominated by a towering mountain.
“10 instruments all aimed at a mountain higher than any in the lower 48 states, whose stratigraphic layering records the major breakpoints in the history of Mars’ environments over likely hundreds of millions of years, including those that may have been habitable for life.”
“It’s like a trip down the Grand Canyon 150 years ago, with the same sense of adventure, but with a lot of high tech equipment,” Grotzinger told me.
MSL also has an international team of over 250 science investigators and instruments spread across the US, Europe and Russia.
MESSENGER is the first probe to orbit Mercury and the one year primary mission was recently extended by NASA.
Sean Solomon, of the Carnegie Institution of Washington, leads the MESSENGER mission as principal investigator. The Johns Hopkins University Applied Physics Laboratory built and operates the MESSENGER spacecraft for NASA.
“Planetary has 3 missions there… Dawn, MESSENGER, and MSL,” Jim Green proudly said to Universe Today regarding the Popular Science magazine awards. Green is the director, Planetary Science Division, NASA Headquarters, Washington
“Three out of 10 [awards] is a tremendous recognition of the fact that each one of our planetary missions goes to a different environment and takes on new and unique measurements providing us new discoveries and constantly changes how we view nature, ourselves, and our place in the universe.”

Once the realm of science fiction, the prospect of colonizing other planets is getting closer to reality. The most logical first place, besides the Moon, has always been Mars. Venus is a bit closer, but the scorching conditions there are, well, much less than ideal. There is still technology that needs to be developed before we can send humans to Mars at all, never mind stay there permanently. But now there may be help from an unlikely and lowly companion. – worms.
Ok, not the kind of worms you find in your garden, but tiny microscopic worms called Caenorhabditis elegans (C. elegans). Similar biologically to humans in some ways, they are being studied by scientists at the University of Nottingham in the UK to help see how people are affected by long-duration space travel.
In December 2006, 4,000 of them were sent into orbit aboard the Space Shuttle Discovery. This was followed by another mission in 2009. The scientists found that in space, the worms develop and produce progeny just as they do on Earth. The research has been published in the November 30, 2011 issue of Interface, a journal of The Royal Society.
According to Dr. Nathaniel Szewczyk of the Division of Clinical Physiology in the School of Graduate Entry Medicine, “While it may seem surprising, many of the biological changes that happen during spaceflight affect astronauts and worms and in the same way. We have been able to show that worms can grow and reproduce in space for long enough to reach another planet and that we can remotely monitor their health. As a result C. elegans is a cost-effective option for discovering and studying the biological effects of deep space missions. Ultimately, we are now in a position to be able to remotely grow and study an animal on another planet.”
He added: “Worms allow us to detect changes in growth, development, reproduction and behaviour in response to environmental conditions such as toxins or in response to deep space missions. Given the high failure rate of Mars missions use of worms allows us to safely and relatively cheaply test spacecraft systems prior to manned missions.”
So while a manned space mission to Mars is still a ways off, some lucky worms may get there first, making the voyage of a lifetime, even if they don’t realize it!

CAPE CANAVERAL, Fla – It is a mission years in the making. However, it would not be possible without the hard work of an army’s worth of engineers – and the systems that they built. How many different systems and engines are required to get the Mars Science Laboratory (MSL) rover named Curiosity to the surface of the Red Planet? The answer might surprise you.
Including the two engines that are part of the Atlas V 541 launch vehicle, it will take 50 different engines and thrusters in total to work perfectly to successfully deliver Curiosity to the dusty plains of Mars.
Starting with the launch vehicle itself, there are six separate engines that power the six-wheeled rover, safely ensconced in its fairing, out of Earth’s gravity well. For the first leg of the journey four powerful Solid Rocket Boosters (SRBs) provided by Aerojet (each of these provides 400,000 lbs of thrust) will launch the rover out of Earth’s atmosphere.
The United Launch Alliance (ULA) Atlas launch vehicle has two rocket engines that provide the remaining amount of thrust required to get MSL to orbit and send the rover on its way to Mars. The first is the Russian-built RD-180 engine (whose thrust is split between two engine bells) the second is the Centaur second stage. There are four Aerojet solid rocket motors that help the booster and Centaur upper stage to separate.
The Centaur’s trajectory is controlled by both thrust vector control of the main engine as well as a Reaction Control System or RCS comprised of liquid hydrazine propulsion systems (there are twelve roll control thrusters on the Centaur upper stage).
MSL’s cruise stage separates entirely from the Centaur upper stage and is on the long road to the Red Planet. The cruise stage has eight one-pound-thrust hydrazine thrusters that are used for trajectory maneuvers for the nine-month journey to Mars. These are used for minor corrections to keep the spacecraft on the correct course.
Curiosity’s first physical encounter with the Martian environment is referred to as Entry, Descent and Landing (EDL) – more commonly known as “six minutes of terror” – the point when mission control, back on Earth, loses contact with the spacecraft as it enters the Martian atmosphere.

Even though Mars only has roughly one percent of Earth’s atmosphere, the friction of the atmosphere caused by a spacecraft impacting it at 13,200 miles per hour (about 5,900 meters per second) – is enough to melt Curiosity if it were exposed to these extremes. The heat shield, located at the base of the cruise stage, prevents this from happening.
The heat shield, provided by Lockheed-Martin, on MSL’s cruise stage is 14.8 feet (4.5 meters) in diameter. By comparison, the heat shields that were used on the Apollo manned missions to the Moon were 13 feet (4 meters) in diameter and the ones that allowed the Mars Exploration Rovers Spirit and Opportunity to safely reach the surface of Mars were 8.7 feet (2.65 meters) in diameter.
[/caption]
At this point in the mission eight engines, each providing 68 pounds of thrust come into play. These engines provide all of the trajectory control during EDL – meaning they will fire almost continuously.
Shortly thereafter – BOOM – the parachute deploy. Then the heat shield is ejected. After the parachute slow the spacecraft down to a sufficient degree, both they and the back aeroshell depart leaving just the rover and its jet pack.
During the landing phase the “SkyCrane” comes alive with eight powerful hydrazine engines, each of which give Curiosity 800 pounds of thrust. Aerojet’s Redmond Site Executive, Roger Myers, talked a bit about this segment of the landing, considered by many to be the most dramatic method of getting a vehicle to the surface of Mars.
“Because of the control requirements for the SkyCrane these engines had to be very throttleable,” Myers said. “Keeping the SkyCrane level is a must, you must have very fine control of those engines to ensure stability.”
If all has gone well up to this point, the Curiosity rover will be lowered the remaining distance to the ground via cables. Once contact with the Martian surface is detected, the cables are cut, the SkyCrane’s engines throttle up and the jet pack flies off to conduct a controlled crash (approximately a mile or so away from where Curiosity is located).
Every powered landing on Mars conducted in the U.S. unmanned space program has utilized Aerojet’s thrusters. The reliability of these small engines was recently proven – in a mission that is now almost three-and-a-half decades old.
Voyager recently conducted a course correction some 34 years after it was launched – highlighting the capability of these thrusters to perform well after launch.
“Our engines have allowed missions to fly to every planet in the solar system and we are currently on our way to Mercury and Pluto,” Myers said. “When NASA explores the solar system – Aerojet provides the propulsion components.”
NASA’s Curiosity Mars Science Lab (MSL) rover is speeding away from Earth on a 352-million-mile (567-million-kilometer) journey to Mars following a gorgeous liftoff from Cape Canaveral Air Force Station, Florida aboard a United Launch Alliance Atlas V rocket at 10:02 a.m. EST on Nov. 26.
Enjoy the gallery of Curiosity launch images collected here from the Universe Today team and local photographers as well as NASA and United Launch Alliance.
The historic voyage of the largest and most sophisticated Martian rover ever built by humans seeks to determine if Mars ever offered conditions favorable for the genesis of microbial life.
“We are very excited about sending the world’s most advanced scientific laboratory to Mars,” NASA Administrator Charles Bolden said. “MSL will tell us critical things we need to know about Mars, and while it advances science, we’ll be working on the capabilities for a human mission to the Red Planet and to other destinations where we’ve never been.”
The mission will pioneer a first of its kind precision landing technology and a sky- crane touchdown to deliver the car sized rover to the foothills of a towering and layered mountain inside Gale Crater on Aug. 6, 2012.
Curiosity is packed to the gills with 10 state of the art science instruments that are seeking the signs of life in the form of organic molecules – the carbon based building blocks of life as we know it.
The robot is equipped with a drill and scoop at the end of its robotic arm to gather soil and powdered samples of rock interiors, then sieve and parcel out these samples into analytical laboratory instruments inside the rover.
The 1 ton Curiosity rover sports a science payload that’s 15 times heavier than NASA’s previous set of rovers – Spirit and Opportunity – which landed on Mars in 2004. Some of the tools are the first of their kind on Mars, such as a laser-firing instrument for checking the elemental composition of rocks from a distance, and an X-ray diffraction instrument for definitive identification of minerals in powdered samples.

It hasn’t been a great year for Roscosmos, the Russian Federal Space Agency. In the last twelve months, it has lost four major missions on top of the aerospace industry’s failure to produce its planned number of spacecraft.
For the most part, lost missions conjure up feelings of despair for the spacecraft from a scientific or exploration perspective – what does the silent satellite or failed launch mean for the agency’s immediate and overall goals? But there’s another side to lost missions that are less common. What does a lost mission or failed launch mean for the people responsible? All four missions Roscosmos has lost in the last year have been substantial. In December 2010, a Proton-M booster failed to put three Glonass-M satellites in orbit. These were meant to enhance Russia’s Global Navigation Satellite System, the Russian counterpart to America’s GPS system, and just recently, Russia successfully launched replacements.
In February, a Rokot booster carrying the Geo-IK-2 satellite ended in failure. The satellite was designed to build on Russia’s geodesic research. Acting as a precise reference point, it would help scientists take accurate measurements of the Earth’s shape and the properties of its gravitational field and support such fields as cartography, missile guidance, study of tectonic plate movements, ocean tides, and ice conditions.
The loss of these missions was doubtless devastating for the teams who designed them, but the After the loss of Geo-IK-2, a number of senior space industry officials were fired and Roscosmos’s chief, Anatoly Perminov, was forced to resign.
In August, another Proton-M rocket failed to launch an Ekspress-AM4. The communications satellite was designed to provide digital television and secure government communications throughout the Russian Federation extending far into Siberia and the Far East.
This failure prompted further disciplinary action. A Russian State Commission of inquiry was established to determine the reasons for the failure. The International Launch Services (ILS), a joint US-Russian venture with exclusive rights to launch commercial payload from the Baikonur Cosmodrome in Kazakhstan, formed its own Failure Review Oversight Board to review Roscosmos‘ final internal report. The final verdict was both missions were lost due to negligence.
Things didn’t get better for the Russian Space Agency. Only a week after the loss of Eskpress-AM4, A Soyuz-U booster failed. Its cargo, the Progress M-12 expendable cargo spacecraft, never reached the crew waiting for its contents aboard the International Space Station.
Now, it looks like further harsh disciplinary action might befall the scientists and engineers behind the failed Phobos-Grunt. Designed to land on Mars’ larger moon and return a soil sample, the spacecraft got stuck in Earth orbit in November. Russian President Dmitry Medvedev has suggested that those responsible for the failure need to be punished. They could he fined, he said. He even went so far as to suggest criminal prosecution. The threat might be directed at Lavochkin, the company that built Phobos-Grunt.
It’s possible Medvedev is protecting the Russian people who, like Americans, foot the bill of their nation’s space program. But he might not be. The failures do, after all, deal a serious blow to Russia’s technological pride and standing as a power in space.
“I am not suggesting putting them up against the wall like under Josef Vissarionovich (Stalin), but seriously punish either financially or, if the fault is obvious, it could be a disciplinary or even criminal punishment,” Medvedev said.
Surprisingly, or perhaps not, Roscosmos isn’t the only Russian industry to be target by Medvedev’s calls for disciplinary action. Similar calls have been made for disciplinary action after carelessness, corruption, and problems within Russia’s infrastructure, such as a riverboat sinking in July that killed 122. The difference is that no one dies when an unmanned spacecraft fails to complete its mission.
What does a spacecraft look like as it lights-out for another world? This incredible time-lapse video was taken by astronomers at the Sir Thomas Brisbane Planetarium in Australia. The sequence shows a plume drifting against the background stars, probably caused by venting from the Centaur rocket stage that sent the Mars Science Laboratory/Curiosity Rover on its way to the Red Planet, after it carried out a burn over the Indian Ocean on November 26, 2011.
Brisbane Planetarium Curator Mark Rigby said that he and photographer/amateur astronomer Duncan Waldron, along with another planetarium staff member were likely the only people who saw this amazing sight, as they have received no other reports of similar observations.
Rigby said they are “are over the Moon – or higher” from seeing the departure of the Mars Science Laboratory, its rocket stage and plume above Australia on Sunday. “It is a real shame that we couldn’t have woken up everyone that didn’t have clouds,” Rigby wrote on the Planetarium’s Facebook page. “Even we didn’t expect to see such a spectacle. Can you imagine the feeling if there had been a crew onboard heading for Mars?”
Rigby first saw the plume at 2:15am local time, (16:15 UT) and said it was “a one-degree elongated cloud of VERY easy naked eye brightness.” Duncan Waldron also saw it starting at about 2:30pm and began to photograph it until it faded. Nonetheless, he captured a unique timelapse covering 21 minutes until 3am.
Here is one of Waldron’s images, below:

Congrats to the Sir Thomas Brisbane Planetarium team for capturing such an amazing and historical sight!
Atop a towering inferno of sparkling flames and billowing ash, Humankinds millennial long quest to ascertain “Are We Alone ?” soared skywards today (Nov. 26) with a sophisticated spaceship named ‘Curiosity’ – NASA’s newest, biggest and most up to date robotic surveyor that’s specifically tasked to hunt for the ‘Ingredients of Life’ on Mars, the most ‘Earth-like’ planet in our Solar System.
Curiosity’s noble goal is to meticulously gather and sift through samples of Martian soil and rocks in pursuit of the tell-tale signatures of life in the form of organic molecules – the carbon based building blocks of life as we know it – as well as clays and sulfate minerals that may preserve evidence of habitats and environments that could support the genesis of Martian microbial life forms, past or present.
The Atlas V booster carrying Curiosity to the Red Planet vaulted off the launch pad on 2 million pounds of thrust and put on a spectacular sky show for the throngs of spectators who journeyed to the Kennedy Space Center from across the globe, crowded around the Florida Space Coast’s beaches, waterways and roadways and came to witness firsthand the liftoff of the $2.5 Billion Curiosity Mars Science Lab (MSL) rover.
The car sized Curiosity rover is the most ambitious, important and far reaching science probe ever sent to the Red Planet – and the likes of which we have never seen or attempted before.
“Science fiction is now science fact,” said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters at the post launch briefing for reporters at KSC. “We’re flying to Mars. We’ll get it on the ground… and see what we find.”
“’Ecstatic’ – in a word, NASA is Ecstatic. We have started a new Era in the Exploration of Mars with this mission – technologically and scientifically. MSL is enormous, the equivalent of 3 missions frankly.”
“We’re exactly where we want to be, moving fast and cruising to Mars.”
NASA is utilizing an unprecedented, rocket powered precision descent system to guide Curiosity to a pinpoint touch down inside the Gale Crater landing site, with all six wheels deployed.
Gale Crater is 154 km (96 mi) wide. It is dominated by layered terrain and an enormous mountain rising some 5 km (3 mi) above the crater floor which exhibits exposures of minerals that may have preserved evidence of ancient or extant Martian life.
“I hope we have more work than the scientists can actually handle. I expect them all to be overrun with data that they’ve never seen before.”
“The first images from the bottom of Gale Crater should be stunning. The public will see vistas we’ve never seen before. It will be like sitting at the bottom of the Grand Canyon,” said McCuistion.
The 197 ft tall Atlas booster’s powerful liquid and solid fueled engines ignited precisely on time with a flash and thunderous roar that grew more intense as the expanding plume of smoke and fire trailed behind the rapidly ascending rockets tail.
The Atlas rockets first stage is comprised of twin Russian built RD-180 liquid fueled engines and four US built solid rocket motors.
The engines powered the accelerating climb to space and propelled the booster away from the US East Coast as it majestically arced over in between broken layers of clouds. The four solids jettisoned 1 minute and 55 seconds later. The liquid fueled core continued firing until its propellants were expended and dropped away at T plus four and one half minutes.
The hydrogen fueled Centaur second stage successfully fired twice and placed the probe on an Earth escape trajectory at 22,500 MPH.
The Atlas V initially lofted the spacecraft into Earth orbit and then, with a second burst from the Centaur, pushed it out of Earth orbit into a 352-million-mile (567-million-kilometer) journey to Mars.
MSL spacecraft separation of the solar powered cruise stage stack from the Centaur upper stage occurred at T plus 44 minutes and was beautifully captured on a live NASA TV streaming video feed.
“Our spacecraft is in excellent health and it’s on its way to Mars,” said Pete Theisinger, Mars Science Laboratory Project Manager from the Jet Propulsion Laboratory in California at the briefing. “I want to thank the launch team, United Launch Alliance, NASA’s Launch Services Program and NASA’s Kennedy Space Center for their help getting MSL into space.”
“The launch vehicle has given us a first rate injection into our trajectory and we’re in cruise mode. The spacecraft is in communication, thermally stable and power positive.”
“I’m very happy.”
“Our first trajectory correction maneuver will be in about two weeks,” Theisinger added.
“We’ll do instrument checkouts in the next several weeks and continue with thorough preparations for the landing on Mars and operations on the surface.”
Curiosity is a 900 kg (2000 pound) behemoth. She measures 3 meters (10 ft) in length and is nearly twice the size and five times as heavy as Spirit and Opportunity, NASA’s prior set of twin Martian robots.
NASA was only given enough money to build 1 rover this time.
“We are ready to go for landing on the surface of Mars, and we couldn’t be happier,” said John Grotzinger, Mars Science Laboratory Project Scientist from the California Institute of Technology at the briefing. “I think this mission will be a great one. It is an important next step in NASA’s overall goal to address the issue of life in the universe.”
Curiosity is equipped with a powerful 75 kilogram (165 pounds) array of 10 state-of-the-art science instruments weighing 15 times more than its predecessor’s science payloads.
A drill and scoop located at the end of the robotic arm will gather soil and powdered samples of rock interiors, then sieve and parcel out these samples into analytical laboratory instruments inside the rover. A laser will zap rocks to determine elemental composition.
“We are not a life detection mission.”
“It is important to distinguish that as an intermediate mission between the Mars Exploration Rovers, which was the search for water, and future missions, which may undertake life detection.”
“Our mission is about looking for ancient habitable environments – a time on Mars which is very different from the conditions on Mars today.”
“The promise of Mars Science Laboratory, assuming that all things behave nominally, is we can deliver to you a history of formerly, potentially habitable environments on Mars,” Grotzinger said at the briefing. “But the expectation that we’re going to find organic carbon, that’s the hope of Mars Science Laboratory. It’s a long shot, but we’re going to try.”
Today’s liftoff was the culmination of about 10 years of efforts by the more than 250 science team members and the diligent work of thousands more researchers, engineers and technicians spread around numerous locations across the United States and NASA’s international partners including Canada, Germany, Russia, Spain and France.
“Scientists chose the site they wanted to go to for the first time in history, because of the precision engineering landing system. We are going to the very best place we could find, exactly where we want to go.”
“I can’t wait to get on the ground,” said Grotzinger.

NASA’s Curiosity Mars rover, the most technologically complex and scientifically capable robot built by humans to explore the surface of another celestial body, is poised to liftoff on Nov. 26 and will enable a quantum leap in mankind’s pursuit of Martian microbes and signatures of life beyond Earth.
“The Mars Science Lab and the rover Curiosity is ‘locked and loaded’, ready for final countdown on Saturday’s launch to Mars,” said Colleen Hartman, assistant associate administrator in NASA’s Science Mission Directorate, at a pre-launch media briefing at the Kennedy Space Center (KSC).
The $2.5 Billion robotic explorer remains on track for an on time liftoff aboard a United Launch Alliance Atlas V rocket at 10:02 a.m. on Nov. 26 from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.
NASA managers and spacecraft contractors gave the “Go-Ahead” for proceeding towards Saturday’s launch at the Launch Readiness Review on Wednesday, Nov. 23. The next milestone is to move the Atlas V rocket 1800 ft. from its preparation and assembly gantry inside the Vertical Integration Facility at the Cape.
“We plan on rolling the vehicle out of the Vertical Integration Facility on Friday morning [Nov. 25] ,” said NASA Launch Director Omar Baez at the briefing. “We should be on the way to the pad by 8 a.m.”
The launch window on Nov. 26 is open until 11:14 a.m. and the current weather prognosis is favorable with chances rated at 70 percent “GO”.
“The final launch rehearsal – using the real vehicle ! – went perfectly, said NASA Mars manager Rob Manning, in an exclusive interview with Universe Today. Manning is the Curiosity Chief Engineer at NASA’s Jet Propulsion Laboratory in Pasadena, Calif.
“I was happy.”
“The folks at KSCs Payload Handling Facility and at JPL’s cruise mission support area (CMSA) – normally a boisterous bunch – worked quietly and professionally thru to T-4 minutes and a simulated fake hold followed by a restart and a recycle (shut down) due to a sail boat floating too close to the range,” Manning told me.
Readers may recall that NASA’s JUNO Jupiter orbiter launch in August was delayed by an hour when an errant boat sailed into the Atlantic Ocean exclusion zone.
“This rover, Curiosity rover, is really a rover on steroids. It’s an order of magnitude more capable than anything we have ever launched to any planet in the solar system,” said Hartman.
“It will go longer, it will discover more than we can possibly imagine.”
Curiosity is locked atop the powerful Alliance Atlas V rocket that will propel the 1 ton behemoth on an eight and one half month interplanetary cruise from the alligator filled swamps of the Florida Space Coast to a layered mountain inside Gale Crater on Mars where liquid water once flowed and Martian microbes may once have thrived.
Curiosity is loaded inside the largest aeroshell ever built and that will shield her from the extreme temperatures and intense buffeting friction she’ll suffer while plummeting into the Martian atmosphere at 13,000 MPH (5,900 m/s) upon arrival at the Red Planet in August 2012.
The Curiosity Mars Science Lab (MSL) rover is the most ambitious mission ever sent to Mars and is equipped with a powerful 75 kilogram (165 pounds) array of 10 state-of-the-art science instruments weighing 15 times as much as its predecessor’s science payloads.
Curiosity measures 3 meters (10 ft) in length and weighs 900 kg (2000 pounds), nearly twice the size and five times as heavy as NASA’s prior set of twin robogirls – Spirit and Opportunity.
The science team selected Gale crater as the landing site because it exhibits exposures of clays and hydrated sulfate minerals that formed in the presence of liquid water billions of years ago, indicating a wet history on ancient Mars that could potentially support the genesis of microbial life forms. Water is an essential prerequisite for life as we know it.
Gale Crater is 154 km (96 mi) in diameter and dominated by a layered mountain rising some 5 km (3 mi) above the crater floor.
The car sized rover is being targeted with a first of its kind precision rocket powered descent system to touchdown inside a landing ellipse some 20 by 25 kilometers (12.4 miles by 15.5 miles) wide and astride the towering mountain at a location in the northern region of Gale.
Curiosity’s goal is to search the crater floor and nearby mountain – half the height of Mt. Everest – for the ingredients of life, including water and the organic molecules that we are all composed of.
The robot will deploy its 7 foot long arm to collect soil and rock samples to assess their composition and determine if any organic materials are present – organics have not previously been detected on Mars.
Curiosity will also vaporize rocks with a laser to determine which elements are present, look for subsurface water in the form of hydrogen, and assess the weather and radiation environments
“After the rocket powered descent, the Sky-Crane maneuver deploys the rover and we land on the mobility system, said Pete Theisinger, MSL project manager from the Jet Propulsion Laboratory in Pasadena, Calif., at the briefing.
The rover will rover about 20 kilometers in the first year. Curiosity has no life limiting constraints. The longevity depends on the health of the rovers components and instruments.
“We’ve had our normal challenges and hiccups that we have in these kinds of major operations, but things have gone extremely smoothly and we’re fully prepared to go on Saturday morning. We hope that the weather cooperates, said Theisinger
Missions to Mars are exceedingly difficult and have been a death trap for many orbiters and landers.
“Mars really is the Bermuda Triangle of the solar system,” said Hartman. “It’s the ‘death planet,’ and the United States of America is the only nation in the world that has ever landed and driven robotic explorers on the surface of Mars. And now we’re set to do it again.”
