Curiosity rover – Two years on Mars

Here’s a brief video from NASA JPL about the status of the Curiosity Rover two years after it landing on Mars:  Curiosity Rover Report (Aug. 5, 2014): A Softer Trek to Mount Sharp

On the second anniversary of landing, NASA’s Curiosity rover on Mars is preparing to navigate through a series of sandy valleys on its way to Mount Sharp. The base of Mount Sharp sits 3 kilometers (1.8 miles) from the rover’s current position.

And here is a release from NASA about the anniversary:

NASA Mars Curiosity Rover: Two Years and Counting on Red Planet 

NASA’s most advanced roving laboratory on Mars celebrates its second anniversary since landing inside the Red Planet’s Gale Crater on Aug. 5, 2012, PDT (Aug. 6, 2012, EDT).

During its first year of operations, the Curiosity rover fulfilled its major science goal of determining whether Mars ever offered environmental conditions favorable for microbial life. Clay-bearing sedimentary rocks on the crater floor in an area called Yellowknife Bay yielded evidence of a lakebed environment billions of years ago that offered fresh water, all of the key elemental ingredients for life, and a chemical source of energy for microbes, if any existed there.

“Before landing, we expected that we would need to drive much farther before answering that habitability question,” said Curiosity Project Scientist John Grotzinger of the California Institute of Technology, Pasadena. “We were able to take advantage of landing very close to an ancient streambed and lake. Now we want to learn more about how environmental conditions on Mars evolved, and we know where to go to do that.”

During its second year, Curiosity has been driving toward long-term science destinations on lower slopes of Mount Sharp. Those destinations are in an area beginning about 2 miles (3 kilometers) southwest of the rover’s current location, but an appetizer outcrop of a base layer of the mountain lies much closer — less than one-third of a mile (500 meters) from Curiosity. The rover team is calling the outcrop “Pahrump Hills.”

For about half of July, the rover team at NASA’s Jet Propulsion Laboratory in Pasadena, California, drove Curiosity across an area of hazardous sharp rocks on Mars called “Zabriskie Plateau.” Damage to Curiosity’s aluminum wheels from driving across similar terrain last year prompted a change in route, with the plan of skirting such rock-studded terrain wherever feasible. The one-eighth mile (200 meters) across Zabriskie Plateau was one of the longest stretches without a suitable detour on the redesigned route toward the long-term science destination.

Another recent challenge appeared last week in the form of unexpected behavior by an onboard computer currently serving as backup. Curiosity carries duplicate main computers. It has been operating on its B-side computer since a problem with the A-side computer prompted the team to command a side swap in February 2013. Work in subsequent weeks of 2013 restored availability of the A-side as a backup in case of B-side trouble. In July, fresh commanding of the rover was suspended for two days while engineers confirmed that the A-side computer remains reliable as a backup.

To help prepare for future human missions to Mars, Curiosity incudes a radiation detector to measure the environment astronauts will encounter on a round-trip between Earth and the Martian surface. The data are consistent with earlier predictions and will help NASA scientists and engineers develop new technologies to protect astronauts in deep space.

In 2016, a Mars lander mission called InSight will launch to take the first look into the deep interior of Mars. The agency also is participating in the European Space Agency’s (ESA’s) 2016 and 2018 ExoMars missions, including providing “Electra” telecommunication radios to ESA’s 2016 orbiter and a critical element of the astrobiology instrument on the 2018 ExoMars rover.

Additionally, NASA recently announced that its next rover going to Mars in 2020 will carry seven carefully selected instruments to conduct unprecedented investigations in science and technology, as well as capabilities needed for humans to pioneer the Red Planet.

Based on the design of the highly successful Mars Science Laboratory rover, Curiosity, the new rover will carry more sophisticated, upgraded hardware and new instruments to conduct geological assessments of the rover’s landing site, determine the potential habitability of the environment, and directly search for signs of ancient Martian life.

Scientists will use the Mars 2020 rover to identify and select a collection of rock and soil samples that will be stored for potential return to Earth by a future mission. The Mars 2020 mission is responsive to the science objectives recommended by the National Research Council’s 2011 Planetary Science Decadal Survey.

The Mars 2020 rover will help further advance our knowledge of how future human explorers could use natural resources available on the surface of the Red Planet. An ability to live off the Martian land would transform future exploration of the planet. Designers of future human expeditions can use this mission to understand the hazards posed by Martian dust and demonstrate technology to process carbon dioxide from the atmosphere to produce oxygen. These experiments will help engineers learn how to use Martian resources to produce oxygen for human respiration and potentially as an oxidizer for rocket fuel.

The Mars 2020 rover is part of the agency’s Mars Exploration Program, which includes the Opportunity and Curiosity rovers, the Odyssey and Mars Reconnaissance Orbiter spacecraft currently orbiting the planet, and the MAVEN orbiter, which is set to arrive at the Red Planet in September and will study the Martian upper atmosphere.

NASA’s Mars Exploration Program seeks to characterize and understand Mars as a dynamic system, including its present and past environment, climate cycles, geology and biological potential. In parallel, NASA is developing the human spaceflight capabilities needed for future round-trip missions to Mars.

Mars One Exchange opens with Mason Peck discussing 1-way journeys

The Mars One project to send a private expedition to the Red Planet has created the Mars One Community Platform for interaction among participants and supporters of the project. A new feature of the community platform is the Mars One Exchange where “expert advisers to Mars One will answer your questions”. In the debut of the Exchange, Dr. Mason Peck,  Cornell professor and a former chief technologist at NASA, discusses the one-way aspect of the Mars One plan:

Rosetta nears comet rendezvous

The European Space Agency’s Rosetta spacecraft will rendezvous with  Comet 67P/Churyumov-Gerasimenko on Wednesday.  Find lots of info, images, videos, etc of the approach and rendezvous at the webstie Rosetta | rendevous with a comet.

A livestream webcast will start on Wednesday at 08:00UTC (4:00 am EDT).  Here’s the Rosetta timeline for events in this initial encounter.

Find updates at ESA Rosetta Mission (ESA_Rosetta) on Twitter.
