To celebrate reaching this longevity milestone, which had been set as one of the mission's goals from the start, the Curiosity team planned staffing a special day, with women fulfilling 76 out of 102 operational roles.
"I see this as a chance to illustrate to girls and young women that there's not just a place for them in technical fields, but a wide range of jobs and disciplines that are part of the team needed for a project as exciting as a rover on Mars," said Colette Lohr, an engineer at NASA's Jet Propulsion Laboratory, Pasadena, California.
"There's no practical way any one person could learn all the disciplines needed for operating Curiosity," she said. "It takes a team and we rely on each other."
Disciplines range from soil science to software engineering, from chemistry to cartography, in duties ranging from assessing rover-temperature data freshly arriving from Mars to choosing where to point the rover's cameras. Descriptions of the roles, along with names and locations of the team members filling them today, are part of Curiosity Women's Day information available at:
Lohr's role today is strategic mission manager, which means she is responsible for review and approval of plans being developed and modified during the day for rover activities more than three or four days in the future.
She and most of the other engineers and managers on the team are at JPL in California. Today's team, not atypically, also includes members working in 11 other U.S. states, from Massachusetts to Montana, and four other nations: Canada, France, Russia and Spain. Each of the rover's 10 science instruments has people responsible for evaluating newly received data and planning to get more data. Other scientists participating in operations serve on theme groups that pull together information from multiple instruments and choose priorities for upcoming activities.
Curiosity Deputy Project Scientist Joy Crisp of JPL helped organize the special day and will fill the project scientist role, providing scientific leadership in the strategic planning process. She said, "The team has both scientists and engineers, but it's one team working together to accomplish the mission goals."
Each day's rover activities must be planned to fit within budgets of how much time, power and data-downlink capacity are available.
The operational roles fall into categories of tactical, supra-tactical and strategic, which focus, respectively, on the next day's rover activities, the activities two to five days ahead, and planning for weeks or months ahead.
"While some people are focused on today's plan for tomorrow, we need other people to be looking further ahead," Crisp said. "We wouldn't be able to plan complex activities for the rover if we started from scratch each day. We do a lot of work to get a head start on each day."
The operations team for Curiosity is larger than the operations teams for the previous generation of rovers, NASA's Mars Exploration Rovers Spirit and Opportunity. In an experience similar to Women's Curiosity Day, one day in February 2008, Spirit's tactical operations team of about 30 people was almost entirely women.
NASA's Mars Science Laboratory Project is using Curiosity to assess ancient habitable environments and major changes in Martian environmental conditions. JPL, a division of the California Institute of Technology in Pasadena, built the rover and manages the project for NASA's Science Mission Directorate in Washington.
