“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.

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.

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.”

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.

[/caption]‘Mars Trek – Curiosity’s Search for Undiscovered Life’ has its galaxy wide premiere Saturday morning Nov. 26 at 10:02 a.m. EST – live on NASA TV.
NASA’s quest ‘In Search of Life’ takes a bold leap in less than 12 hours with the Nov. 26 blastoff of “Curiosity”, the most complex and scientifically advanced robotic explorer ever sent to survey the surface of another world. The 103 minute launch window closes at 11:45 a.m. EST.
Curiosity and the United Launch Alliance Atlas V rocket that will thrust her to the Red Planet are poised for liftoff after being rolled out to Space Launch Complex 41 around 8 a.m. this morning under the watchful eyes of ground crews, mission scientists, reporters and photographers.
Universe Today was there – reporting live on all the history making and thrilling events !
Launch day weather remains favorable, with only a 30 percent chance of conditions prohibiting liftoff, said Air Force meteorologists. A low cloud ceiling is the sole concern at this time.

The 1.2 million pound booster was pushed 1800 feet along rail tracks by twin diesel powered trackmobiles from the prelaunch preparation and assembly gantry inside the Vertical Integration Facility out to launch pad 41 at Cape Canaveral Air Force Station.
The 197 foot tall booster is equipped with 4 strap on solid rocket motors and generates some 2 million pounds of liftoff thrust according to Vernon Thorp, Atlas Program manager for ULA.
Curiosity is NASA’s next Mars rover and also quite possibly the last US built Mars rover due to severe cuts to NASA planetary science budget.
After an eight and one half month and 354 million mile (570 million km) interplanetary journey, Curiosity will slam into the thin Martian atmosphere at 13,000 MPH and utilize an unprecedented rocket powered pinpoint landing system known as the Sky Crane to touch down with all six wheels deployed inside Gale Crater.
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 which exhibits exposures of minerals that may have preserved evidence of past or present Martian life.

Immediately after touchdown, the 1 ton rover will transmit telemetry so that engineers back on Earth can assess the rover’s status.
“When we first land we want to ascertain the integrity and health of the vehicle and look at the surrounding terrain, said Pete Theisinger, MSL project manager from the Jet Propulsion Laboratory in Pasadena, Calif., at the briefing.
“The rover’s mast will be deployed on the second day and we’ll get pictures.”
“Shortly thereafter we will begin our science investigations. The radiation (RAD) and subsurface hydrogen detection (DAN) instruments will start right away since they are passive.”
The rover will drive inside the first week.
“The cameras will be used to select targets. We will go up to the valuable targets. With the cameras and instruments we will determine which ones to sample” said Theisinger.
“Then we’ll deploy the arm which contains scientific equipment and collect samples with a percussion drill. The samples will be injected into the two science instruments for analysis that are located on the rover.”
“The SAM and ChemMin instruments will look for organic molecules and isotope ratios as well as identify and quantify the minerals in the rock and soil samples. It could be up to 2 to 3 months before we take the first samples,” explained Theisinger.
MSL is powered by a nuclear battery and is expected to operate for a minimum of one Martian year, equivalent to 687 days on Earth. NASA hopes the 6 foot tall rover will last alot longer.

“We are ready and so is Curiosity !”
Says Rob Manning, Curiosity Chief Engineer at NASA’s Jet Propulsion Laboratory in Pasadena, Calif – in an exclusive interview with Universe Today for all fans of Curiosity and the unprecedented voyage of Science and Discovery about to take flight to Mars on November 26. Manning was also the Chief Engineer for the Entry, Descent and Landing (EDL) of NASA’s phenomenally successful Spirit, Opportunity and Phoenix Mars robotic explorers.
Read Rob Manning’s special greeting about Curiosity to readers of Universe Today below.
Meet Rob and other JPL Mars engineers in the cool Video describing the ‘Challanges of Getting to Mars’ – below
Curiosity is NASA’s next Mars rover and her MMRTG nuclear power source has been installed at the launch pad through special access panels in the Atlas booster payload fairing and protective aeroshell on Nov. 17.
The huge 1-ton robot is now due to blastoff for the Red Planet on Saturday, November 26 at 10: 02 a.m. EST from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida. The launch window is open for one hour and 43 minutes.
Liftoff was postponed by one day to replace a battery in the on board flight termination system required in case the rocket were to veer off course.
Here is the very latest Curiosty update status from JPL’s Rob Manning as of Sunday evening – Nov. 20
“All seems well here at JPL in Pasadena,” Manning told me.
“We are having our last rehearsal at 1:30 a.m. on Monday, Nov 21.
“Weird ! As of a few hours ago the last human hands (in gloves) closed out the hatch door on the entry aeroshell and the two large doors in the rocket fairing have been closed. What is weird about it is that finally finally she is powered up and alone.”
“She has never been this alone before. Ironically all eyes are still upon her. Our team is monitoring her vitals 24-7,” Manning explained.
“The Challenges of Getting to Mars’ – Video caption: Meet Curiosity Chief Engineer Rob Manning and more members of the Curiosity Mars Rover Engineering Team at NASA’s Jet Propulsion Laboratory explain the final assembly of Curiosity at the Kennedy Space Center and how Curiosity will land use the rocket assisted Sky Crane.
“By this time next week, Curiosity will be heading for the home she was meant for.”
“Soon she will feel the cold walls of deep space on her radiators. The x-band transmitter and receiver will have an broken view of the sky (with Earth but a shiny blue dot off to her left). The penetrating rays of the sun will push electrons out of the solar panels and keep her battery charged. (And perhaps a few solar flares will pass by, just to keep things interesting.)”
“Earth can be a rough place for a rover not designed for our planet. Worse are those of us who have poked and prodded, tested beyond spec and pushed in ways that can only be done on Earth.”
“Sometimes we over-do it and push near the breaking point. We are not perfect after all but we need to know that she will do what needs to be done for her very own survival. Well she seems to have survived us.”
“Of course Curiosity will never really be alone. We are right there with her every step of the way. She is us.”

“I will be at JPL during launch,” said Manning.
The JPL team is also working day and night to insure that the do or die Mars Insertion burn fires as planned.
“Once the Deep Space Network acquires the signal, I want to be there to make sure that we did not fail her and that the transition from being the Atlas’s payload to interplanetary cruise is as painless as possible.”
“It will be a bit of a surprise if we did not have a bit of a surprise – but we are ready and so is Curiosity”
Curiosity and the Atlas V booster that will propel her to Mars will roll out to Launch Pad 41 at the Florida Space Coast on Friday morning, Nov. 24, the day after the Thanksgiving holiday.
NASA TV will carry the MSL launch live
After a 10 month interplanetary journey to Mars, Curiosity will plummet through the atmosphere and fire up the rocket powered descent stage and ‘Sky Crane’ to safely touchdown astride a layered mountain at the Gale Crater landing site in August 2012.
Curiosity has 10 science instruments to search for evidence about whether Mars has had environments favorable for microbial life, including the 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.

Nov 19 Update: MSL launch delayed 24 h to Nov. 26 – details later
In just 7 days, Earth’s most advanced robotic roving emissary will liftoff from Florida on a fantastic journey to the Red Planet and the search for extraterrestrial life will take a quantum leap forward. Scientists are thrilled that the noble endeavor of the rover Curiosity is finally at hand after seven years of painstaking work.
NASA’s Curiosity Mars Science Laboratory (MSL) rover is vastly more capable than any other roving vehicle ever sent to the surface of another celestial body. Mars is the most Earth-like planet in our Solar System and a prime target to investigate for the genesis of life beyond our home planet.
Curiosity is all buttoned up inside an aeroshell at a seaside launch pad atop an Atlas V rocket and final preparations are underway at the Florida Space Coast leading to a morning liftoff at 10:25 a.m. EST on Nov. 25, the day after the Thanksgiving holiday.
“MSL is ready to go,” said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington, at a media briefing. “It’s a momentous occasion. We’re just thrilled that we’re at this point.”
“Curiosity is ‘Seeking the Signs of Life’, but is not a life detection mission. It is equipped with state-of-the-art science instruments.”
This oblique view of Gale Crater shows the landing site and the mound of layered rocks that NASA's Mars Science Laboratory will investigate. The landing site is in the smooth area in front of the mound. Image credit: NASA/JPL-Caltech/ASU/UA
“It’s not your father’s rover. It’s a 2000 pound machine that’s over 6 feet tall – truly a wonder of engineering,” McCuistion stated.
“Curiosity is the best of US imagination and US innovation. And we have partners from France, Canada, Germany, Russia and Spain.”
“Curiosity sits squarely in the middle of our two decade long strategic plan of Mars exploration and will bridge the gap scientifically and technically from the past decade to the next decade.”
“Mars Science Laboratory builds upon the improved understanding about Mars gained from current and recent missions,” said McCuistion. “This mission advances technologies and science that will move us toward missions to return samples from and eventually send humans to Mars.”

The car sized rover is due to arrive at Mars in August 2012 and land inside Gale Crater near the base of a towering and layered Martian mountain, some 5 kilometers (3 miles) high. Gale Crater is 154 km (96 mi) in diameter.
The landing site was chosen because it offers multiple locations with different types of geologic environments that are potentially habitable and may have preserved evidence about the development of microbial life, if it ever formed.
Gale Crater is believed to contain clays and hydrated minerals that formed in liquid water eons ago and over billions of years in time. Water is an essential prerequisite for the genesis of life as we know it.

The one ton robot is a behemoth, measuring 3 meters (10 ft) in length and is nearly twice the size and five times as heavy as NASA’s prior set of twin rovers – Spirit and Opportunity.
Curiosity is equipped with a powerful array of 10 science instruments weighing 15 times as much as its predecessor’s science payloads. The rover can search for the ingredients of life including water and the organic molecules that we are all made of.
Curiosity will embark on a minimum two year expedition across the craters highly varied terrain, collecting and analyzing rock and soil samples in a way that’s never been done before beyond Earth.
Eventually our emissary will approach the foothills and climb the Martian mountain in search of hitherto untouched minerals and habitable environments that could potentially have supported life’s genesis.
With each science mission, NASA seeks to take a leap forward in capability and technology to vastly enhance the science return – not just to repeat past missions. MSL is no exception.
Watch a dramatic action packed animation of the landing and exploration here:
Curiosity was designed at the start to be vastly more capable than any prior surface robotic explorer, said Ashwin Vasavada, Curiosity’s Deputy Project Scientist at NASA’s Jet Propulsion Laboratory in Pasadena, Calif
“This is a Mars scientist’s dream machine.”
Therefore this mission uses new technologies to enable the landing of a heavier science payload and is inherently risky. The one ton weight is far too heavy to employ the air-bag cushioned touchdown system used for Spirit and Opportunity and will use a new landing method instead.
Curiosity will pioneer an unprecedented new precision landing technique as it dives through the Martian atmosphere named the “sky-crane”. In the final stages of touchdown, a rocket-powered descent stage will fire thusters to slow the descent and then lower the rover on a tether like a kind of sky-crane and then safely set Curiosity down onto the ground.
NASA has about three weeks to get Curiosity off the ground from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida before the planetary alignments change and the launch window to Mars closes for another 26 months.
“Preparations are on track for launching at our first opportunity,” said Pete Theisinger, MSL project manager at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif. “If weather or other factors prevent launching then, we have more opportunities through Dec. 18.”

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
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.

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.

NASA’s solar powered Juno spacecraft blasted off today (Aug.5)from Cape Canaveral today to begin a 2.8 billion kilometer science trek to discover the genesis of Jupiter hidden deep inside the planet’s interior.
Upon arrival at Jupiter in July 2016, JUNO will fire its braking rockets and go into polar orbit and circle the planet 33 times over about one year. The goal is to find out more about the planets origins, interior structure and atmosphere, observe the aurora, map the intense magnetic field and investigate the existence of a solid planetary core.
The spacecraft is healthy and the solar panels successfully deployed.
Check out the photo album of Juno’s launch from the Universe Today team of Alan Walters and Ken Kremer.
“Jupiter is the Rosetta Stone of our solar system,” said Scott Bolton, Juno’s principal investigator from the Southwest Research Institute in San Antonio. “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.”

“Today, with the launch of the Juno spacecraft, NASA began a journey to yet another new frontier,” NASA Administrator Charles Bolden said. “The future of exploration includes cutting-edge science like this to help us better understand our solar system and an ever-increasing array of challenging destinations.”

In less than one week’s time, NASA’s $1.1 Billion Juno probe will blast off on the most powerful Atlas V rocket ever built and embark on a five year cruise to Jupiter where it will seek to elucidate the mysteries of the birth and evolution of our solar system’s largest planet and how that knowledge applies to the remaining planets.
The stage was set for Juno’s liftoff on August 5 at 11:34 a.m. after the solar-powered spacecraft was mated atop the Atlas V rocket at Space Launch Complex 41 at Cape Canaveral and firmly bolted in place at 10:42 a.m. EDT on July 27.
“We’re about to start our journey to Jupiter to unlock the secrets of the early solar system,” said Scott Bolton, the mission’s principal investigator from the Southwest Research Institute in San Antonio. “After eight years of development, the spacecraft is ready for its important mission.”

The launch window for Juno extends from Aug. 5 through Aug. 26. The launch time on Aug. 5 opens at 11:34 a.m. EDT and closes at 12:43 p.m. EDT. Juno is the second mission in NASA’s New Frontiers program.
JUNO’s three giant solar panels will unfurl about five minutes after payload separation following the launch, said Jan Chodas, Juno’s project manager at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif.
The probe will cartwheel through space during its five year trek to Jupiter.
Upon arrival in July 2016, JUNO will fire its braking rockets and go into polar orbit and circle Jupiter 33 times over about one year.

“Juno will become the first polar orbiting spacecraft at Jupiter. Not only are we over the poles, but we’re getting closer to Jupiter in our orbit than any other spacecraft has gone,” Bolton elaborated at a briefing for reporters at the Kennedy Space Center. “We’re only 5,000 kilometers above the cloud tops and so we’re skimming right over those cloud tops and we’re actually dipping down beneath the radiation belts, which is a very important thing for us. Because those radiation belts at Jupiter are the most hazardous region in the entire solar system other than going right to the sun itself.”
“Jupiter probably formed first. It’s the largest of all the planets and in fact it’s got more material in it than all the rest of the solar system combined. If I took everything in the solar system except the sun, it could all fit inside Jupiter. So we want to know the recipe.”
