After taking a well deserved and unavoidable break during April’s solar conjunction with Mars that blocked two way communication with Earth, NASA’s powerful Martian fleet of orbiters and rovers have reestablished contact and are alive and well and ready to Rock ‘n Roll ‘n Drill.
“Both orbiters and both rovers are in good health after conjunction,” said NASA JPL spokesman Guy Webster exclusively to Universe Today.
Curiosity’s Chief Scientist John Grotzinger confirmed to me today (May 1) that further drilling around the site of the initial John Klein outcrop bore hole is a top near term priority.
The goal is to search for the chemical ingredients of life.
“We’ll drill a second sample,” Grotzinger told Universe Today exclusively. Grotzinger, of the California Institute of Technology in Pasadena, Calif., leads NASA’s Curiosity Mars Science Laboratory mission.
“We’ll move a small bit, either with the arm or the wheels, and then drill another hole to confirm what we found in the John Klein hole.”
Earth, Mars and the Sun have been lined up in nearly a straight line for the past several weeks, which effectively blocked virtually all contact with NASA’s four pronged investigative Armada at the Red Planet.
NASA’s Red Planet fleet consists of the Curiosity (MSL) and Opportunity (MER) surface rovers as well as the long lived Mars Odyssey (MO) and Mars Reconnaissance Orbiter (MRO) robotic orbiters circling overhead. ESA’s Mars Express orbiter is also exploring the Red Planet.
“All have been in communications,” Webster told me today, May 1.
The NASA spacecraft are functioning normally and beginning to transmit the science data collected and stored in on board memory during the conjunction period when a commanding moratorium was in effect.
“Lots of data that had been stored on MRO during conjunction has been downlinked,” Webster confirmed to Universe Today.
And NASA is already transmitting and issuing new marching orders to the Martian Armada to resume their investigations into unveiling the mysteries of the Red Planet and determine whether life ever existed eons ago or today.
“New commanding, post-conjunction has been sent to both orbiters and Opportunity.”
“And the sequence is being developed today for sending to Curiosity tonight (May 1), as scheduled more than a month ago,” Webster explained.
“We’ll spend the next few sols transitioning over to new flight software that gives the rover additional capabilities,” said Grotzinger.
“After that we’ll spend some time testing out the science instruments on the B-side rover compute element – that we booted to before conjunction.”
Curiosity is at work inside the Yellowknife Bay basin just south of the Martian equator. Opportunity is exploring the rim of Endeavour crater at the Cape York rim segment.
Mars Solar Conjunction is a normal celestial event that occurs naturally about every 26 months. The science and engineering teams take painstaking preparatory efforts to insure no harm comes to the spacecraft during the conjunction period when they have no chance to assess or intervene in case problems arise.
So it’s great news and a huge relief to the large science and operations teams handling NASA’s Martian assets to learn that all is well.
Since the sun can disrupt and garble communications, mission controllers suspended transmissions and commands so as not to inadvertently create serious problems that could damage the fleet in a worst case scenario.
So what’s on tap for Curiosity and Opportunity in the near term ?
“For the first few days for Curiosity we will be installing a software upgrade.”
“For both rovers, the science teams will be making decisions about how much more to do at current locations before moving on,” Webster told me.
The Opportunity science team has said that the long lived robot has pretty much finished investigating the Cape York area at Endeavour crater where she made the fantastic discovery of phyllosilicates clay minerals that form in neutral water.
Signals from Opportunity received a few days ago on April 27 indicated that the robot had briefly entered a standby auto mode while collecting imagery of the sun.
NASA reported today that all operations with Opportunity was “back under ground control, executing a sequence of commands sent by the rover team”, had returned to normal and the robot exited the precautionary status.
“The Curiosity team has said they want to do at least one more drilling in Yellowknife Bay area,” according to Webster.
Curiosity has already accomplished her primary task and discovered a habitable zone that possesses the key ingredients needed for potential alien microbes to once have thrived in the distant past on the Red Planet when it was warmer and wetter.
The robot found widespread evidence for repeated episodes of flowing liquid water, hydrated mineral veins and phyllosilicates clay minerals on the floor of her Gale Crater landing site after analyzing the first powder ever drilled from a Martian rock.

During conjunction Curiosity collected weather, radiation and water measurements but no imagery.
