Where do we go next in our quest for knowledge of the Red Planet?


We in the USA had best watch the Mars Science Laboratory (CURIOSITY) carefully as we seem to be pulling out of further missions to Mars, unless you think we are going to send astronauts there without knowing how to survive the riggers of space.

Much to think about in this blog.
I second Alyssa's enthusiasm for Kim Stanley Robinson's Red Mars.
- LRK -

---------------------

The amazing men and women of the National Aeronautics and Space Administration landed the Curiosity rover on Mars last night. But the piece of writing that perhaps best encapsulates the wild joy at the Jet Propulsion Lab, and the meaning of their accomplishment, was published almost 20 years before, on January 1, 1993. I hope everyone will forgive me quoting Kim Stanley Robinson’s introduction to Red Mars, the first of his masterful trilogy about the colonization of the Red Planet, at length here, because it’s the most powerful meditation on the meaning of Mars that I know, and it’s so strikingly applicable here (and make it worth it by going out andbuying the book if my repeated proselytization for it hasn’t convinced you already).
snip

In Robinson’s vision, we sent the first colonizing mission to Mars in 2026. President Obama’s FY 2013 budget proposes cutting NASA’s planetary science budget from $1.5 billion to $1.2 billionand ending the U.S. partnership with the E.U. to send probes to Mars on two planned missions in 2016 and 2018—this year, the Jet Propulsion Lab’s open house was marked by a bake sale to call attention to the proposed cuts. What the scientists at JPL did last night was a critical part of our future in space not simply because they did something extremely difficult that will advance our understanding of the planet that’s fascinated so many of us so deeply and for so long, but because they helped keep the dream alive at all, reminding of what it’s like to watch the future arrive, and how cheap it is to purchase in comparison to what we spend to maintain conflicts and policies that mire us in the past.

Mixed opinions on where we go with missions to Mars.

Should NASA Ditch Manned Missions To Mars?

NASA's overarching goal of sending astronauts to Mars may not be worth the time, money and trouble, a prominent researcher says.

NASA's human spaceflight efforts have long been geared toward eventually putting boots on the Red Planet. But the agency should think seriously about ditching this plan, for the benefits of a manned Mars mission may not justify its enormous costs, said space architect Brent Sherwood of NASA's Jet Propulsion Laboratory in Pasadena, Calif.
"Our rationale for exploring Mars, I think, is perhaps fatally weak," Sherwood said during a presentation with NASA's Future In-Space Operations working group Wednesday (Aug. 1).
snip
---------------------
If you live in the USA much at stake in where we go in the future. 
Watch how much money is raised for adds to support the presidential elections. Wonder what I could do with some of those $$$?

For some more thoughts you might be interested in what our Apollo 17 Astronaut, Dr. Harrison H. Schmitt has to say.
- LRK -

---------------------
snip
By Dr. Harrison H. Schmitt. Prologue: (“Is there a path forward for United States’ space policy? When a new President takes office in 2013, he or she should propose to Congress that we start space policy and its administration from scratch. A new agency, the National Space Exploration Administration (NSEA), should be charged with specifically enabling America’s and its partners’ exploration of deep space, inherently stimulating education, technology, and national focus. The existing component parts of NASA should be spread among other agencies with the only exception being activities related to U.S. obligations to its partners in the International Space Station (ISS).” — HHS). The Foreword was written by Michael D. Griffin, noted physicist, aerospace engineer and NASA Administrator (2005-2009): (“Jack makes the case for space as no one else can, and he shows how and why we are on the wrong path— leaving the rest of us with the question: what can we do to obtain the leadership we need instead of the leadership we have?”— MDG).

Curiosity and the Solar Storm


One of the major problems with sending humans to space on long trips will be how much radiation they may receive.  The more we can learn about this hazard the better.  The Mars Rover, Curiosity, is on its way to Mars and will be measuring what radiation might hit it.
- LRK -
---------------------------------------------------------
http://science.nasa.gov/science-news/science-at-nasa/2011/14dec_mslrad/
There was no danger of a collision—Mars rover vs. solar storm.  Racing forward at 2 million mph, the plasma cloud outpaced Curiosity’s rocket by a wide margin. 
Next time could be different, however.  With solar activity on the upswing (Solar Max is expected in 2012-2013) it’s only a matter of time before a CME engulfs the Mars-bound rover.
That suits some researchers just fine.  As Don Hassler of the Southwest Research Institute (SWRI) in Boulder, Colorado, explains, “We look forward to such encounters because Curiosity is equipped to study solar storms."
snip
As important as RAD’s cruise phase measurements are, the instrument’s primary mission doesn’t really begin until it lands on the Red Planet. 
Mars has a very thin atmosphere and no global magnetic field to protect it from space radiation.  Energetic particles reaching ground level might be dangerous to life--both future human astronauts and extant Martian microbes.  RAD will find out how much shielding human explorers need on the surface of Mars.  RAD will also help researchers estimate how far below ground a microbe might have to go to reach a radiation “safe zone.” 
Solar storms are just for starters. Stay tuned to Science@NASA for the second installment of this story:Curiosity and the Habitability Mars.

---------------------------------------------------------
Footnote:1Posner notes that only the most powerful CMEs will still be accelerating particles when they are as far from sun as Curiosity will be.  For a typical CME, the main thing RAD will detect is the modulation of galactic cosmic rays passing through the CME.  Cosmic ray modulation could reveal new information about the interior structure of these storm clouds.

NASA's Space Network provided space communication services for the launch vehicle. NASA's Deep Space Network will provide spacecraft acquisition and mission communication.

Whatever vehicle takes humans to space, finding a way to protect them from harmful radiations is going to be a problem that needs to be solved.

About Us

The goal of NASA's Space Radiation Program (SRP) is to enable humans to explore space without exceeding an acceptable level of risk from exposure to space radiation.
To achieve this goal, the SRP pursues a robust and active research program that encompasses biological, biomedical and radiation physics expertise to provide:
  • Recommendations for space radiation permissible exposure limits for exploration missions
  • Discovery of the mechanisms of biological effects from celestial radiation such as protons and heavy ions, including potential differences between celestial and terresterial radiation, such as X-rays or gamma-rays in producing biological effects
  • Radiobiological data, projection models, and computational tools to assess and project astronauts risk of cancer, central nervous system and degenerative diseases, and acute radiation syndromes from space radiation
  • Computational tools and models to project astronaut risk and to assess vehicle design for radiation protection
  • Assessment of updated technologies if needed, for monitoring radiation exposure, and recommendations on technologies to be used operationally
  • Uncertainty reductions to enable radiation protection design and crew constraints for lunar and Mars missions
  • Discovery of biological countermeasures for space radiation risks, and the accurate assessment of the effectiveness of physical, biological, or biological countermeasures or mitigations
The purpose of this web site is to communicate news and to promote awareness of the SRP research program and activities.  The web site is produced and managed by the Universities Space Research Association Division of Space Life Sciences.

This Way to Mars: How Technologies Borrowed from Robotic Missions Could Deliver Astronauts to Deep Space


Bryan sent me a link to an article in the December Scientific American about how we might find our way to Deep Space.
[See link below - LRK -]
Whether the ideas presented will create more interest remains to be seen.

Having read the article I wonder if this will just result in more plans that eventually get dropped for lack of continued interest or money.  

I have been reading some of David S. F. Portree's blogs about previous plans for going to space that didn't materialize. We seem to be good at generating ideas but not so good at following through to implementation. If you check out some of links in the blog below you will see what I mean.

Recently a correspondent asked me to identify my top 10 favorite Beyond Apollo articles. Here's the list, in case anyone else is interested. I found that I couldn't stop at 10, so I decided to list one for every 10 Beyond Apollo articles. I think that this list is a good place for a newcomer to start their exploration of Beyond Apollo, which currently amounts to more than 230 articles.

We will be watching how the latest Mars rover mission, Curiosity, does on its way to Mars. Even while still in its shroud the mission begins with turning on the Radiation Assessment Detector (RAD).  Wish them luck on its way to a Martian landing.

RELEASE: 11-414

NASA MARS-BOUND ROVER BEGINS RESEARCH IN SPACE

WASHINGTON -- NASA's car-sized Curiosity rover has begun monitoring space radiation during its 8-month trip from Earth to Mars. The research will aid in planning for future human missions to the Red Planet.

Curiosity launched on Nov. 26 from Cape Canaveral, Fla., aboard the Mars Science Laboratory (MSL). The rover carries an instrument called the Radiation Assessment Detector (RAD) that monitors high-energy 
atomic and subatomic particles from the sun, distant supernovas and other sources. 

These particles constitute radiation that could be harmful to any microbes or astronauts in space or on Mars. The rover also will monitor radiation on the surface of Mars after its August 2012 landing. 

"RAD is serving as a proxy for an astronaut inside a spacecraft on the way to Mars,"  said Don Hassler, RAD's principal investigator from the Southwest Research Institute in Boulder, Colo. " The instrument is deep inside the spacecraft, the way an astronaut would be. Understanding the effects of the spacecraft on the radiation field will be valuable in designing craft for astronauts to travel to Mars."

And while reading about ways to get to Mars, just happened to see the movie Red Planet on cable TV.  Not the best but points out that things can go wrong.  Doesn't help that you used some military hardware for your robot, AMEE which complicates your crash landing.

- LRK -

------------------------------------------
Red Planet is a 2000 Technicolor science fiction film directed by Antony Hoffman, starringVal Kilmer and Carrie-Anne Moss. It was released on November 10, 2000.

Plot
In 2056 AD, Earth is in ecologic crisis as a consequence of pollution and overpopulation. Meanwhile, automated interplanetary missions have been seeding Mars with atmosphere-producing algae for twenty years as the first stage in terraforming the planet. When the oxygen quantity produced by the algae is inexplicably reduced, the crew of Mars-1investigates, and must continue the mission of terraforming the planet for human colonization.
snip

The landing craft is damaged entering the Martian atmosphere, veers off course, and crash-lands far from their landing zone near the habitat. In the process, they lose track of "AMEE"(Autonomous Mapping Exploration and Evasion), a military combat robot re-purposed to serve as their "Mars surface navigator", and Chantillas suffers a ruptured spleen in the crash landing. With limited air, Chantillas is left behind to allow the others to complete the mission.


snip


Critical response


The film received negative reviews, with only a 14% "rotten" rating on Rotten Tomatoes based on 100 reviews.[2] Stephen Holden's review in the New York Times was almost entirely negative, calling the film "a leaden, skimpily plotted space-age Outward Bound adventure with vague allegorical aspirations that remain entirely unrealized."[3]


Errors
snip
Due to significant scientific inaccuracies, NASA refused to serve as a scientific adviser for the film, which it normally does for science fiction films. "The science was just so off the wall that eventually we felt, 'You guys go ahead and make your movie.' If there's something that's going to be so misleading to the public that we don't want to participate, then we'll say no," said Bert Ulrich, a NASA spokesperson. "The big thing is, we want to make sure we're not misleading the public completely."[5]

------------------------------------------

Hmmmm, must watch out for those significant scientific inaccuracies.

Mars Rover 'Curiosity' Grows Up, Rolls for the First Time

Mom had her 100th birthday on 7/22/10 and about that time the Mars Mission Laboratory rover, Curiosity was getting itself together to take its first steps.

Mars Rover 'Curiosity' Grows Up, Rolls for the First Time
Analysis by Ian O'Neill
Mon Jul 26, 2010 04:43 AM ET

Last week, the next Mars rover -- set to be launched to the Red Planet in 2011 -- grew by 1 meter when NASA technicians and engineers attached the Remote Sensing Mast to the robot's roof. The mast carries three sets of cameras, allowing the Mars Science Laboratory (MSL) to 'see' the Martian landscape, helping it navigate, take photographs and carry out experiments.

snip

The car-sized MSL, called 'Curiosity,' now stands at an impressive 2 meters tall, easily dwarfing the current Mars Exploration Rovers, Opportunity and Spirit.

Construction of the rover has advanced very quickly over the last few days, and on July 23 engineers commanded Curiosity to take its first, slow steps. Housed inside a clean room at NASA's Jet Propulsion Laboratory, Pasadena, Calif., and attached to computers via a thick set of umbilical-like cables, a live webcast watched the robot gingerly roll around.

Watch the video of Curiosity successfully reverse for the fist time across the clean room mats:

--------------------------------------

It takes a lot longer to birth a rover than it does a human and a bit more expensive.  Back in 2003 there was a gleam in the eye of the scientists who would send another rover to Mars, with expectations of launching in 2009.  Sometimes your best laid plans just have to get put off while you contemplate another delivery date, say November of 2011.  This will be okay as your previous rovers have done very well and managed to survive a lot longer than expected.

Rover Technology Development and Infusion for the 2009 Mars Science Laboratory Mission
Richard Volpe and Stephen Peters

Abstract
After the 2003 Mars Exploration Rovers (MER) Mission, NASA plans to send a larger, longer life Mobile Science Laboratory (MSL) in 2009. This rover is planned to last 500 days, travel ten kilometers, and demonstrate autonomous capabilities that reduce the number of communication cycles now needed to achieve successful completion of activities on the surface.

Specifically, there are three categories of activity now being addressed by technology development efforts in The Mars Technology Program (MTP): long range traverse, instrument placement, and autonomous science data processing. These technologies are being developed by competitively selected teams of researchers both in and out of NASA. A multi-stage technology integration and validation process brings these distributed elements into a common software environment for rover testing and validation. Based on this validation, some software elements are being identified for incorporation in MSL mission software.

MSL flight and ground software is based on the Mission Data System (MDS) architecture under development at The Jet Propulsion Laboratory, Califomia Institute of Technology. MDS provides a system engineering methodology and a software architecture based on identifying the states of the system, and how these states are estimated and controlled.  The mission will include significant mission operations automation in the form of mission activity expansion, planning, scheduling, and constraint and flight rule checking within an integrated environment. The mission will also include significant autonomy for onboard anomaly detection, analysis, and response, including limited replanning.

http://en.wikipedia.org/wiki/Mars_Science_Laboratory

The Mars Science Laboratory (MSL), known as Curiosity,[2][3] is a NASA rover scheduled to be launched in November 2011[4] and would perform the first-ever precision landing on Mars. It is a rover that will assess whether Mars ever was, or is still today, an environment able to support microbial life. In other words, its mission is to determine the planet's habitability. It will also analyze samples scooped up from the soil and drilled powders from rocks.[5]

The MSL rover will be over five times as heavy as and carry over ten times the weight of scientific instruments as the Spirit or Opportunity rovers.[6] The United States, Canada, Germany, France, Russia and Spain will provide the instruments on board. The MSL rover will be launched by an Atlas V 541 rocket and will be expected to operate for at least 1 Martian year (668 Martian sols/686 Earth days) as it explores with greater range than any previous Mars rover.

Mars Science Laboratory is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of Mars, and is a project managed by NASA's Jet Propulsion Laboratory. The total cost of the MSL project is about $2.3 billion USD.[7]

Curiosity: NASA's Epic New Mars Rover

Mars rovers "Spirit" and "Opportunity" were successful beyond NASA's wildest dreams. Now they're building a new, nuclear-powered Mini Cooper-sized rover to be lowered onto Mars by a hovering drop ship in 2013. Meet "Curiosity," the new Mars Science Laboratory.

If we can love cars on Earth, we sure as heck can love them when they're shot across the cosmos to land on another planet to do some pretty astounding science. Take a couple minutes to watch the above animation and it becomes abundantly clear NASA is aiming for a whole different level of robotic exploration with its next rover program.  The Mars Science Laboratory program was originally started back in 2003 with an estimated price tag of $1.62B, since then it's undergone delays while new technologies were invented to support the ambitious plans and suffered a major setback when over 1,000 parts were manufactured from substandard titanium. The current estimated costs for the program is right around $2.4B, pocket change.

Mars rover Curiosity to seek answers (images)
May 21, 2010 12:16 PM PDT

NASA got a great deal of mileage out of the Mars rovers Spirit and Opportunity, which have lasted far longer than the 90 days originally expected of them when they landed in January 2004. Just this week, in fact, NASA said that Opportunity has surpassed the longevity record of 6 years, 116 days for operation on Mars, surpassing the Viking 1 lander. Spirit, meanwhile, may be done for. Bogged down in loose Martian soil, it may not have been able to position itself to get a good recharge from its solar panels.

Back on Earth, NASA is working on the next generation of Mars rover, named Curiosity, a bigger model that the space agency this week said it hopes to launch between November 25 and December 18, 2011, with a landing on Mars to occur between August 6 and August 20, 2012.

The Mars Science Laboratory mission is scheduled to launch in late 2011. The contents of the MSL Science Corner, including descriptions of the instruments, sampling hardware, and operations, have been updated to reflect changes that have occurred during the development of the hardware and planning for the 2011 opportunity. At present, the entire flight system is undergoing assembly and testing at the Jet Propulsion Laboratory.

So another year and some months to wait.

Go to school, get a PhD, join a mission and spend the rest of your career working to make it happen.
Want to move a mountain?  One stone at a time will do it, providing you have a life time to spend picking up stones.

 As I mentioned at the beginning, mom is 100 years young.  She has seen a lot of changes. If you live as long maybe you will see "Curiosity" land on Mars, or even something similar land on the Moon. I guess a rover needs to look into those holes that have been reported since humans have already been there, although they haven't done that.
