Future Mars missions: Can humans trump robots?
How soon before humans hike around the landscape of Mars? Artist's idea illustrates crewmembers involved in sample analysis on Mars. / NASA
For decades scientists have backed the idea of sending robotics to accumulate Martian rocks and return them to Earth, a job that should be feasible well before humans crunch their boots into the distant dunes of the Red Planet. The idea of landing, scooping up, and hauling back to our world specimens from that interesting globe has actually long been promoted as the Holy Grail of prototype objectives by Mars exploration coordinators. This view was echoed in late September by a summary report from NASA's Mars Program Planning Group (MPPG). Former NASA program manager Orlando Figueroa chaired the blue-ribbon team of MPPG members that were tasked to reformulate the company 's Mars Exploration Program.

| 0.0884994 | "Maybe," Zubrin said. "It is certainly possible to propose alternative robotic mission sets consisting of assortments of orbiters, rovers, aircraft, [and] surface networks ... that might produce a greater science return than the Mars sample return mission, much sooner." |
| 0.0874409 | "However, that said, if the scientific community really believes that a robotic Mars sample is so valuable that it is worth sacrificing all the other kinds of science they could do with the money, then it is imperative that NASA develop the most efficient Mars sample return plan, to allow the sample to be obtained as quickly as possible and with the least possible expenditure of funds that could be used for other types of Mars exploration missions," Zubrin said. ... |

| 0.0783285 | "In short, if we want to get a sample from Mars, we should devise a plan to get a sample from Mars in the simplest, cheapest, fastest, and most direct fashion possible, and not let the mission be made into a Christmas tree on which to hang all the ornaments in the bureaucracy's wish box of useless and costly multi-decade delays," Zubrin concluded. ... |

Key:
- Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
- The Mean is meant to be an indicator of an individual's average comment sentiment.
- The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).
Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
