Following the brilliant success of the advanced sky crane system that delivered Curiosity to Mars in August 2012, and therefore the rover's successes since then, National Aeronautics and Space Administration is operating briskly on plans for another Curiosity-class Mars rover to visit the red planet, it's hoped, throughout the 2020 launch chance.
Functionally, the 2020 rover could be a virtual similar to Curiosity . it'll even utilize the backup atomic power supply from Curiosity (one of the few left within the U.S. inventory). This leads to over a billion greenbacks in calculable value savings by reducing development prices. Yet, despite this reliance on current technology, engineers can have to be compelled to introduce several new styles for this mission to achieve success.
First, there's the mission itself. Once the 2004 Mars Exploration Rovers (MERs) Spirit and chance confirmed the proof of a wet Mars within the distant past (tantalizing guarantees came from each from orbit and by guide in 1997), Curiosity's purpose was confirmed as associate degree biology mission. By this, National Aeronautics and Space Administration wasn't speech communication that it'd hunt for life the approach Scandinavian did within the 1970s; rather, it'd obtain erst liveable environments on and just below the Martian surface. The instruments carried aboard would be specifically accommodate that mission goal. From the ChemCam laser-firing spectroscope, to the surface-to-air missile and Chemin aboard laboratories, to the Powder Acquisition Drill System, or PADS, drill, the whole rover was optimized for that task whereas still being capable of different analysis activities.
With voluminous results flowing in from Curiosity's nearly 2 Earth-years on Mars, the teachings learned is applied to the 2020 rover and its mission style. This new machine can serve 2 primary duties. First, it'll still refine knowledge on once-habitable environments and take a look at for biosignatures — chemical signs of past life. Second, it'll determine rocks and soils that look promising — and for selected sites it's planned to require core samples, then store these samples for doable later pickup by a sample-return mission, nonetheless|so far|thus far|up to now|hitherto|heretofore|yet|til now|until now} to be determined (and not yet funded).
Moving on to technological demands, it's this increased sample-gathering and caching capability that may be beggary for innovation. The new rover can carry associate degree updated drill and core-sampling mechanism, associate degree evolved instrument package to spot so analyze sample targets, and a caching mechanism during which up to thirty one samples are going to be keep for ultimate come back to Earth by a ulterior lander, once (and if) approved.
Perhaps not since the Scandinavian program of the Seventies has optimism run therefore high for a Mars mission. For Viking, anticipation focused on basic on-board tests of soil samples in a shot to search out Earth-like microorganisms. For the 2020 rover, the optimism is burning by doable detection of past (and probably present) life forms. The come back of cached samples could be a abundant larger challenge, involving a landing, cache retrieval, ascension and rendezvous with a orbiter equipped to come back the samples to Earth. ne'er has such associate degree concerned, multi-step mission been tried, and tho' sample-caching is a component of the 2020 mission, a come back trip isn't. because the JPL team members prefer to say, "Mars is tough." ['Innovation the National Aeronautics and Space Administration Way' (US 2014): Book Excerpt ]
Perhaps even more difficult is finding the money to travel there, and within the case of the sample-return, to return back.
So what else is there to introduce for this new mission and its successor? Curiosity has easy, shallow-surface sample-gathering machinery, however robotic deep-drilling and particularly core-extraction technologies area unit still in their infancy. Drilling many inches of rock into powder and transporting many grams of that up into a set drum is one thing; extracting a core sample is way more difficult. Remember, whether or not mudstone or more durable targets, these area unit rocks the rovers are going to be sampling. this may need progressive, however careful, innovations that may be designed, tested, tested Again and deployed to figure during a harsh and remote setting.
Likewise the on-board analytical instrumentation are going to be a challenge. The Scandinavian landers shrank a rudimentary life-science laboratory right down to the scale of a dishwasher. Fast-forward to Curiosity and you've got machines that may take a look at samples to a molecular level, even revealing region analysis and therefore the atom numbers of gasses given off by the baking of rock samples. to look for true biosignatures in rock and soil samples would force even a lot of tactfulness and technological acumen.

The 2020 rover can believe heavily on Curiosity's self-made platform in terms of overall style and performance. The variations are going to be principally within the above-named areas — instrumentation and sampling enhancements. however a ulterior landing mission — to come back with Martian soil samples — would need a replacement overall style and another major overhaul of the landing system. guide and therefore the MER rovers used airbags to bounce to a landing, scouring off energy as they did therefore. Curiosity used (and the 2020 rover can use) target-hunting entry and therefore the sky-crane system, the wonderful rocket pack and rappelling device that worked therefore well in 2012. this transformation was settled by the mass of the lander and a unbroken want for improved preciseness within the landings. A sample-return mission, which might on purpose be meant to hunt out the cache of samples left by the 2020 rover, can possible be heavier still, and a replacement landing system are going to be needed. That system could also be by-product of Curiosity's, however this is often presently underneath study. abundant of the engineering team from Curiosity was affected to the 2020 mission, and a few were sent off to review new and various landing technologies. This may entail a folding platform, that is crushed throughout touchdown, engrossing abundant of the energy. Or it'd utilize one thing involving larger rockets in numerous a configuration. Or it can be a not-yet-conceived system as outrageous because the sky crane appeared once the globe initial ordered eyes upon it back within the early 2000s.
New and innovative steering techniques are underneath development, supported expertise from Curiosity. That orbiter was target-hunting to its slender landing passageway by guidance including locomote microwave radar. Put simply, it knew its precise location relative to Mars once it encountered the atmosphere, so calculated the direction changes to achieve the appointed spot at air current Crater. speed and region measurements from the outer hull refined this approach path. it had been a stimulating little bit of computation.
The Mars 2020 mission can cut back the scale of the landing zone — or "landing conic section," within the expression — right down to regarding four miles by seven miles, smaller than even Curiosity's by 0.5. 2 promising technologies area unit being studied. The first, known as vary trigger, releases the parachute solely when measure the gap to the surface and factorization in different variables like wind speed and air density (previous landers did this by measure velocity). The second, piece of land relative navigation, combines measurements of the bearing of far-famed landmarks with different aboard measurements to additional refine landing accuracy. These and different technologies can facilitate to guide the 2020 rover to its prime landing website, and ulterior sample-return missions, if any, to the sample cache the 2020 rover prepares.
At the top of this pathway lies, of course, the goal of human exploration of Mars. Unless another target becomes therefore attractive on replace it, Mars remains the Holy Grail of human voyage. elements of Curiosity's mission, specifically the radiation detection instrument, area unit important tools for continued to develop a practical mission set up for reaching the terrestrial planet. The 2020 rover can come back even a lot of knowledge important to human survival en-route to, and on, Mars. it's going to additionally take a look at unmoved resource utilization ways, reckoning on the ultimate instrument and experiment picks. Of course, a sample come back would supply a bounty of data regarding however the surface setting is utilised and created safe for human explorers.
But this is often all way within the future. Robotic exploration should precede any crewed missions. And with ever-tightening budgets and competitive priorities, the Mars exploration program should stay clever, nimble and innovative to remain on track. regardless of the new styles might entail, you'll be able to take care that the designers, researchers and engineers at JPL can come back up with new, and really possible, surprising ways to deal with the challenges of continued exploration of the terrestrial planet. The spirit of innovation, each in progressive and tumultuous terms, is alive and we have a tendency toll as we prepare to move off, once again, to rove Mars.US to Mars 2020
