Dramatic New NASA Animation Depicts Next Mars Rover in Action

NASA's Mars Science Laboratory Curiosity rover. Curiosity is a mobile robot for investigating Mars' past or present ability to sustain microbial life. Curiosity is being tested in preparation for launch in the fall of 2011. The mast, or rover's "head," rises to about 2.1 meters (6.9 feet) above ground level, about as tall as a basketball player. This mast supports two remote-sensing instruments: the Mast Camera, or "eyes," for stereo color viewing of surrounding terrain and material collected by the arm; and, the ChemCam instrument, which is a laser that vaporizes material from rocks up to about 9 meters (30 feet) away and determines what elements the rocks are made of.

NASA’s next Mars rover, the Curiosity Mars Science Laboratory, will soon embark on a quantum leap in humankind’s scientific exploration of the Martian surface -the most Earthlike planet in our Solar System.

To get a birds eye understanding of Curiosity’s magnificent capabilities, check out the dramatic new high resolution animation below which depicts NASA’s next Mars rover traversing tantalizing terrain for clues to whether Martian microbial life may have existed, evolved and been sustained in past or present times.

The new action packed animation is 11 minutes in length. It depicts sequences starting with Earth departure, smashing through the Martian atmosphere, the nail biting terror of the never before used rocket-backpack sky crane landing system and then progressing through the assorted science instrument capabilities that Curiosity will bring to bear during its minimum two year expedition across hitherto unseen and unexplored Martian landscapes, mountains and craters.

Curiosity is equipped with 10 science instruments. The three meter long robot is five times the weight of any previous Mars rover.

Those who closely follow the adventures of NASA’s Spirit and Opportunity rovers, like myself, will quickly recognize several of the panoramic scenes which have been included to give a realistic feeling of vistas to expect from the car sized Curiosity rover.

Here is a shorter 4 minute animation with expert narration

Along the way you’ll experience Curiosity zapping rocks with a laser, deftly maneuvering her robotic arm and camera mast and retrieving and analyzing Martian soil samples.

“It is a treat for the 2,000 or more people who have worked on the Mars Science Laboratory during the past eight years to watch these action scenes of the hardware the project has developed and assembled,” said Mars Science Laboratory Project Manager Pete Theisinger at NASA’s Jet Propulsion Laboratory, Pasadena, Calif, in a NASA statement. “The animation also provides an exciting view of this mission for any fan of adventure and exploration.”

Also, a drill can collect sample material from inside of rocks and a scoop can pick up samples of soil. The arm can sieve the samples and deliver fine powder to instruments inside the rover for thorough analysis. Credit: NASA/JPL-Caltech

Curiosity was flown this week from her birthplace at NASA’s Jet Propulsion Laboratory in California to her future launch site in Florida aboard a C-17 military cargo transport aircraft.

She arrived at the Shuttle Landing Facility (SLF) at the Kennedy Space Center on June 22. The SLF is the same landing strip where I watched the STS-135 crew arrive for NASA’s final shuttle mission just days earlier days for their final launch countdown training.

NASA has scheduled Curiosity to blast off for the red planet on Nov. 25, 2011 from Cape Canaveral Air Force Station aboard an Atlas V rocket. Curiosity will touchdown in August 2012 at a landing site that will be announced soon by Ed Weiler, NASA Associate Administrator for the Science Mission Directorate in Washington, D.C.

Just over a year from now, NASA’s Curiosity rover should be driving across fascinating new landscapes on the surface of Mars if all goes well. Curiosity is NASA next Mars rover – the Mars Science Laboratory – and is targeted to launch during a three week window that extends from Nov. 25 to Dec. 18, 2011 from Cape Canaveral Air Force Station, Fla..

At NASA’s Jet Propulsion Laboratory (JPL), Pasadena, Calif., engineering specialists have been putting Curiosity through the final phase of mobility tests to check out the driving capability, robotic arm movements and sample collection maneuvers that the robot will carry out while traversing the landing site after plummeting through the Martian atmosphere in August 2012.

Take a good look at this album of newly released images from JPL showing Curiosity from the front and sides, maneuvering all six wheels, climbing obstacles and flexing the robotic arm and turret for science sample collection activities as it will do while exploring the red planet’s surface.

Curiosity is following in the footsteps of the legendary Spirit and Opportunity rovers which landed on opposite side of Mars in 2004.

“The rover and descent stage will be delivered to the Payload Hazardous Servicing Facility at the Kennedy Space Center (KSC) later in June,” Guy Webster, public affairs officer at JPL, told me. An Air Force C-17 transport plane has already delivered the heat shield, back shell and cruise stage on May 12, 2011.

“The testing remaining in California is with engineering models and many operational readiness tests,” Webster elaborated. “Lots of testing remains to be done on the flight system at KSC, including checkouts after shipping, a system test, a fit check with the RTG, tests during final stacking.”

The three meter long rover will explore new terrain that will hopefully provide clues as to whether Mars harbored environmental conditions that may have been favorable to the formation of microbial life beyond Earth and preserved evidence of whether left ever existed in the past and continued through dramatic alterations in Mars history.

NASA is evaluating a list of four potential landing sites that will offer the highest science return and the best chance of finding a potentially habitable zone in a previously unexplored site on the red planet.

UPDATE: According to JPL’s Scott Maxwell on Twitter, the aeroshell was not damaged during the improper lifting, which is good news, as there should be no impact to the launch schedule.

The backshell for the Mars Science Laboratory was damaged last week at Kennedy Space Center when it was lifted improperly, according to Aviation Week. Engineers are now examining the backshell to determine the nature of the damage and how serious it is. There is no word yet on whether this could impact the launch of the Curiosity rover, which is currently set for November 25 of this year. The launch window extends to December 18, but after that the mission would have to wait about 26 months for the next favorable launch window.

An agency spokesman was quoted as saying the damage to the backshell did not appear to be serious. An Air Force C-17 carrying the backshell, cruise stage and heat shield arrived at Kennedy Space Center on May 12, while the rover and its unique the descent stage scheduled to arrive in June. The accident apparently involved the backshell being lifted with a crane in the wrong attitude, placing out-of-specification strain on clamps holding it together.

We’ll keep you posted.

Solar Powered Jupiter bound JUNO lands at Kennedy Space Center for blastoff

The Juno spacecraft passes in front of Jupiter in this artist's depiction. Juno, the second mission in NASA's New Frontiers program, will improve our understanding of the solar system by advancing studies of the origin and evolution of Jupiter. The spacecraft will carry eight instruments to investigate the existence of a solid planetary core, map Jupiter's intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet's auroras.

Juno, NASA’s next big mission bound for the outer planets, has arrived at the Kennedy Space Center to kick off the final leg of launch preparations in anticipation of blastoff for Jupiter this summer.

The huge solar-powered Juno spacecraft will skim to within 4800 kilometers (3000 miles) of the cloud tops of Jupiter to study the origin and evolution of our solar system’s largest planet. Understanding the mechanism of how Jupiter formed will lead to a better understanding of the origin of planetary systems around other stars throughout our galaxy.

Juno will be spinning like a windmill as it fly’s in a highly elliptical polar orbit and investigates the gas giant’s origins, structure, atmosphere and magnetosphere with a suite of nine science instruments.

During the five year cruise to Jupiter, the 3,600 kilogram probe will fly by Earth once in 2013 to pick up speed and accelerate Juno past the asteroid belt on its long journey to the Jovian system where it arrives in July 2016.

Juno will orbit Jupiter 33 times and search for the existence of a solid planetary core, map Jupiter’s intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet’s auroras.

The mission will provide the first detailed glimpse of Jupiter’s poles and is set to last approximately one year. The elliptical orbit will allow Juno to avoid most of Jupiter’s harsh radiation regions that can severely damage the spacecraft systems.

Juno was designed and built by Lockheed Martin Space Systems, Denver, and air shipped in a protective shipping container inside the belly of a U.S. Air Force C-17 Globemaster cargo jet to the Astrotech payload processing facility in Titusville, Fla.

This week the spacecraft begins about four months of final functional testing and integration inside the climate controlled clean room and undergoes a thorough verification that all its systems are healthy. Other processing work before launch includes attachment of the long magnetometer boom and solar arrays which arrived earlier.

Juno is the first solar powered probe to be launched to the outer planets and operate at such a great distance from the sun. Since Jupiter receives 25 times less sunlight than Earth, Juno will carry three giant solar panels, each spanning more than 20 meters (66 feet) in length. They will remain continuously in sunlight from the time they are unfurled after launch through the end of the mission.

“The Juno spacecraft and the team have come a long way since this project was first conceived in 2003,” said Scott Bolton, Juno’s principal investigator, based at Southwest Research Institute in San Antonio, in a statement. “We’re only a few months away from a mission of discovery that could very well rewrite the books on not only how Jupiter was born, but how our solar system came into being.”

Juno is slated to launch aboard the most powerful version of the Atlas V rocket – augmented by 5 solid rocket boosters – from Cape Canaveral, Fla. on August 5. The launch window extends through August 26. Juno is the second mission in NASA’s New Frontiers program.

NASA’s Mars Curiosity Rover will follow Juno to the Atlas launch pad, and is scheduled to liftoff in late November 2011. Read my stories about Curiosity here and here.

Because of cuts to NASA’s budget by politicians in Washington, the long hoped for mission to investigate the Jovian moon Europa may be axed, along with other high priority science missions. Europa may harbor subsurface oceans of liquid water and is a prime target in NASA’s search for life beyond Earth.

Curiosity Mars Rover Almost Complete

[/caption]

NASA’s massive ‘Curiosity’ rover is almost ready to begin the first leg of its long trek to the surface of the Red Planet. Engineers at NASA’s Jet Propulsion Laboratory in California are nearly finished with assembling and testing all the components of the Mars Science Laboratory (MSL) mission (see photos above and below).

The MSL team plans to ship Curiosity as well as the cruise stage, descent stage and back shell to the Kennedy Space Center (KSC) in May and June. After arriving at KSC, all the pieces will be integrated together and tested during final assembly in a clean room. The rover will then be installed inside a 5 meter diameter nose cone, shipped the short distance to Cape Canaveral and then bolted atop an Atlas V rocket (photo below).

The launch window for Curiosity extends from Nov. 25 to Dec. 18, 2011. The first stage of the powerful Atlas V rocket will be augmented with four solid rocket boosters. The Atlas V has previously launched two planetary missions; the Mars Reconnaissance Orbiter (MRO) and the New Horizons mission to Pluto.

Take a long gander at the 3 meter long rover because its appearance is now very much how it will look while it’s roving along intriguing martian landscapes for at least two earth years after landing in August 2012.

The mini-Cooper sized Curiosity rover is equipped with 10 science instruments to investigate Martian soil and rock samples in far greater detail than ever before. Curiosity’s science payload weighs ten times more than any prior Mars rover mission.

The goal is to search for clues to environmental conditions favorable for microbial life and for preserving evidence about whether Martian life ever existed in the past or today. NASA is scrutinizing a list of four potential landing sites for the best chance of finding a habitable zone.

Curiosity Rover Testing in Harsh Mars-like Environment

NASA’s next Mars rover, named Curiosity, is now undergoing crucial tests that are designed to simulate the harsh environmental conditions of the Martian surface that awaits the rover when she lands there in August 2012.

Curiosity, also known as the Mars Science Laboratory or MSL, is the size of a mini-Cooper. It was placed inside a 7.6 meter (25 foot) diameter high vacuum chamber at NASA’s Jet Propulsion Laboratory. Engineers are now conducting an extensive regimen of tests that will check out the performance and operational capabilities of the rover under Mars-like conditions.

Since the atmosphere of Mars is very thin – roughly 0.6% compared to Earth – most of the air was pumped out to simulate the meager atmospheric pressure on the surface of Mars.

The internal chamber temperature was decreased to minus 130 degrees Celsius (minus 202 degrees Fahrenheit) using liquid nitrogen flowing through the chamber walls to approximate the Antarctic like bone chilling cold. Martian lighting conditions are being simulated by a series of powerful lamps.

Upon successful completion of the testing, all components of the MSL spacecraft system will be shipped to the Kennedy Space Center for final integration. This includes the cruise stage, descent stage and back shell.

The launch window for MSL extends from Nov. 25 to Dec. 18, 2011 atop an Atlas V rocket from pad 41 at Cape Canaveral, Florida.

MSL will land using a new and innovative sky crane system instead of airbags. Using the helicopter-like sky crane permits the delivery of a heavier rover to Mars and with more weight devoted to the science payload. Indeed the weight of Curiosity’s science payload is ten times that of any prior Mars rover mission.

MSL also features a precision landing system to more accurately guide the rover to the desired target than past missions, to within an ellipse about 20 kilometers long. After extensive evaluation, four landing sites where water once flowed have been selected for further evaluation. The final decision will come sometime in 2011.

Curiosity is about twice the size and four times the weight compared to NASA’s Spirit and Opportunity Mars Explorations Rovers which landed on Mars back in 2004. Opportunity continues to stream back science data from Mars after seven years. The fate of Spirit is unknown at this time as the plucky rover has been out of contact since entering hibernation in March 2010.

The science goal of Curiosity is to search the landing site for clues about whether environmental conditions favorable for microbial life existed in the past or even today on Mars and whether evidence for life may have been preserved in the geological record.

The rover is being targeted to an area where it is believed that liquid water once flowed and may be habitable. In particular the science teams hope to sample and investigate phyllosilicate clays, which are minerals that form in neutral watery conditions more favorable to the formation of life compared to the more acidic environments investigated thus far by Spirit and Opportunity.

Drop Test for Next Mars Rover’s Sky-Crane Landing System

One of the biggest unknowns for the Mars Science Lab — a.k.a Curiosity — is the landing system, called the Sky Crane, which has never been used before for a spacecraft landing on another planet. It is similar to a sky crane heavy-lift helicopter, and it works like this: after a parachute slows the rover’s descent toward Mars, a rocket-powered backpack will lower the rover on a tether during the final moments before landing. This method allows landing a very large, heavy rover on Mars (instead of the airbag landing systems of previous Mars rovers).

The MSL team conducted a drop test of the Sky Crane, and you can see how it worked in the video, above.
