Mathematician Jack matthievichturned-rover-
Engineers who play an important role in the design of Mars Science Laboratory (
MSL called \"curious)
, Now appears on Wikipedia as \"Jack matthievich\"rock).
\"Jack died a few days after Curiosity landed on August.
With his low-key attitude, I can imagine his smile when he saw that he was now more famous as a rock on Mars than as an engineer.
Who is Jack, what is the important thing about this stone, that he will be respected in this way? Jack matthievich. 1947-2012)
Is the chief engineer of surface operating systems for MSL, which means that he oversees all aspects of how engineers maintain curiosity and uses the greatest advantages to achieve the \"two\" of scientists
Gale crater and its 3-year exploration. 4 miles (5. 5 km)
High central mound.
Jack was also the chief engineer of the Mars probe. -
A small experimental sender (1997)
Long-lasting agents of scientists on another planet for their first land exploration, Mars rover, Spirit (2004-2010)
And opportunities (
Even today, it runs in the crater of endeavor).
Jake Matijevic is one of the two engineers I interviewed working on how scientists can do field science remotely through robotic labs.
At the suggestion of Steve Squires, MER\'s chief researcher in science, Jack helped me understand the views of the engineers and their contributions.
On December 2007, we met at Jack\'s office at the Jet Propulsion Lab in Pasadena, California.
He gracefully talks about how the engineer\'s thinking evolved from a Voyager-like operating spacecraft that flew through planets or around Saturn like Cassini.
Operating the vehicle on the surface is different because you can\'t simply write a program a few months in advance to point out the instrument and take pictures or measurements.
This implementation was developed when operating a Viking lander (1976-1980)
A pair of fixed Laboratories-
Scientists can see what Viking instruments and shovels can\'t get to and what they want to investigate.
Can you place a mobile platform on the surface of Mars?
By the end of 1990, robot engineering-
Computer programming, power systems, instruments, and machinery-
Electronic control of mobility-
Making it possible for the resident experiment, basically a robotic solar panel on wheels equipped with cameras and atoms
Spectrum Analyzer.
The mother ship of the Pathfinder also provided evidenceof-
The concept of airbag packaging with bounce ball landing used by MER.
It is also important that the engineering team, led by Matijevic and Andy Mishkin, come up with a team with coordinated work schedules, computer visualization and programming tools on how to operate the Sojourner rover on a daily basis.
\"Daily command\" includes receiving data from Mars, processing and interpreting data, deciding what to do next, and then writing and testing a program for the next day\'s operation, when the probe wakes up on Mars the next morning, it is transmitted.
Daily command is a huge improvement compared to Viking, where it takes about two weeks to convert the plan into a project to use more primitive tools.
In fact, Viking\'s operations only focus on collecting all the data that the instrument allows.
The requirements for exploring with the touring laboratory are much higher and require prior analysis and action feedback;
For example, without detailed photos about your neighborhood, you don\'t know what\'s interesting and possible to do next.
Placing an arm with an instrument on a rock or soil block requires knowing how the rover is oriented, so the camera and other instruments can be placed precisely on features of interest.
Matijevic explained: in other tasks [
Operation Plan
Be part of the original design and once the instruments and vehicles are deployed, whether as an orbiter or a flyover, you are actually completing the task at that stage.
What you\'re doing with the spacecraft is already clear, even at various design review stages, many years before the start of the mission, before the instrument is deployed.
In the rover mission. .
In an environment where you have little information, you are knocked down and give the charter the opportunity to move forward, explore, and find the use of your instrument.
This requires a real understanding of the engineers of scientists and engineering scientists: What is ability and what is possible?
As the chief engineer of MER, this is a mission to extend the stay of the traveller from a few months to a few years and less than 50 feet (10 m)
More than 20 miles (34 km)
Matijevic and the experienced resident team elaborate on how we operate the rover on the surface of Mars.
They created a joint science.
Engineering planning processes involving more complex and coordinated tools (e. g.
, Photos related to the spectrum analysis showing atoms and chemical components)
It is also planned to conduct \"sports\", hiking and crater surveys for one year or more.
These methods, combined with the technology developed by Phoenix mission (2008)
In order to synchronize the daily operation with the data and commands transmitted by satellites around Mars, today it is used to operate curiosity.
When asked to complete the sentence \"work with the Rover. . .
Matijevic highlights how the engineer\'s imagination is Facing Reality: Oh, it\'s just a humility.
I don\'t care what you think you understand about moving vehicles, which is never the case.
Once you\'re on a different terrain, it\'s a different regime.
I think I learned a lot from driving a car into the sandbox [at JPL]
To understand what is possible and what cannot be done. (laughs)
It\'s not like driving your car.
In our short time together, I saw that Jack was a humble man, and then I understood why in these pioneering years of working on Mars, all the people who studied and were instructed by him deeply felt his death.
So, what is special about the rock of the same name on Mars, \"Jack matthievich?
It is likely to be the basalt formed by volcanic action.
The curious team chose the rock as the right target for the first time to use the detector to contact the rock and soil-
A camera called the Mars Hand Lens Camera (MAHLI)
Can be close-
Color images and a tool called Alpha Particle X-
Ray Spectrometer (APXS)
Used to determine which atomic elements exist.
About as big as football, with flat pyramids on both sides, The Rock offers a convenient opportunity to do the first Test to place 7-foot-long (2. 1 meters)
Accurate Arms and instruments. The mast-
The installed chemical and camera instruments are also programmed as zap\'s laser-
The camera in the same place reads the chemical from the evaporated debris.
Comparing results with APXS helps to cross
Calibrate two instruments.
This is the first \"touch science\" in the MSL mission and Jack will be happy to see that everything is working well.
