Testing of a lightweight robotic helicopter designed to fly in the alien atmosphere of Mars has produced encouraging results in recent months, and NASA officials expect to decide soon whether the aerial drone will accompany the agency\u2019s next rover to the red planet set for liftoff in 2020.<\/p>\n

Engineers at the Jet Propulsion Laboratory have worked on the helicopter design for several years, modifying principles used in drones that fly in Earth\u2019s atmosphere for the more challenging conditions at Mars. The atmospheric pressure on Mars is less than 1 percent that of Earth, and the Martian gravity field is about three-eighths as strong as it is on Earth.<\/p>\n

Jim Watzin, director of NASA\u2019s robotic Mars exploration program at the agency\u2019s headquarters, said last month that an engineering model of the helicopter has completed 86 minutes of flying time in a test chamber configured to simulate the Martian atmosphere.<\/p>\n

\u201cThe system has been built, it\u2019s been ground tested, and then we put it into a chamber that was backfilled at Mars atmosphere (conditions),\u201d Watzin said Feb. 20 in a presentation to the Mars Exploration Program Analysis Group, a panel of scientists that assists NASA in planning Mars missions. \u201cSome parts were removed from the helicopter to compensate for the 1g (gravity) field to get the proper relationship of mass and acceleration at Mars, and we did controlled takeoffs, slewing, translations, hovers and controlled landings in the chamber. We\u2019ve done that multiple times.\u201d<\/p>\n

The helicopter weighs about 4 pounds, or 1.8 kilograms, on Earth. An internal battery is capable of powering the drone for flights lasting between 90 seconds and 2 minutes \u2014 enough time to travel up to 1,000 feet, or 300 meters \u2014 and solar panels can recharge the battery for subsequent flights, Watzin said.<\/p>\n

\u201cNow we\u2019re thinking whether or not it would make sense, and if there would be an opportunity to fly this at some point, potentially maybe even on Mars 2020 as a tech demo,\u201d Watzin said. \u201cBut that decision hasn\u2019t been made, and it will be taken later this spring.\u201d<\/p>\n

The drone has spinning rotors, avionics and sensors to fly autonomously on Mars, without real-time inputs from ground controllers on Earth.<\/p>\n

NASA managers say the helicopter could give scientists better views of rough terrain, where it is unsafe to send a rover. The drone could also scout a rover\u2019s planned drive path for obstacles.<\/p>\n

Jim Green, head of NASA\u2019s planetary science division, said the space agency will examine the technical readiness of the helicopter and the cost of sending it to Mars in 2020.<\/p>\n

\u201cThere are two aspects of it,\u201d Green said Feb. 21. \u201cOne is the feasiblity of a technology demonstration such as what the helicopter concept is moving forward on, and the other part of it is an adequate budget to be able to execute it.<\/p>\n

\u201cIt\u2019s going through its reviews,\u201d Green said. \u201cSo far, it\u2019s doing well, but it has a couple more gates to go through before we\u2019d actually confirm it and fly it.\u201d<\/p>\n

If approved for launch with the Mars 2020 rover, the drone would carry two cameras \u2014 one for navigation and one for higher-resolution color imagery. Mission planners want to ensure the helicopter will not harm the rover itself, so controllers would drive the Mars 2020 rover to a position far away from the drone, reducing the chance of a collision or dust impingement on scientific instruments.<\/p>\n

\u201cThe concept of operations that we looked at for the helicopter involve the rover placing the helicopter on the surface, and then moving several hundred yards away to try to have a safe fly zone so that we can limit the possibility of recontact,\u201d Watzin said.<\/p>\n

Once the helicopter concept is demonstrated on Mars, future rovers \u2014 and potentially eventual astronaut crews \u2014 could use the technology on a more regular basis.<\/p>\n

\u201cLooking forward to an operational system, we don\u2019t see anything in the architecture that is exceptionally life limiting,\u201d Watzin said. \u201cIf we were to fly the helicopter as a tech demonstration on something like Mars 2020, we would envision a very small number of flights to prove the aerodynamic and handling characteristics, and the concept of operations, and that would be the end of the demonstration.\u201d<\/p>\n

NASA announced Wednesday that the Mars 2020 rover, which is set for liftoff in July 2020 on a United Launch Alliance Atlas 5 rocket, has officially entered its assembly, test and launch operations phase. The milestone marks the start of final construction of the rover and the descent stage that will deliver it to the surface of Mars.<\/p>\n

Based on the rover and sky crane lander design from NASA\u2019s Curiosity mission, Mars 2020 will reach the red planet in February 2021. The rover carries instruments to study its geological environment after touchdown, a zoom-capable camera, sensors to look for organic compounds, and a radar to map the underground structure at the landing site.<\/p>\n

Another instrument on the Mars 2020 rover will attempt to produce oxygen from carbon dioxide in the Martian atmosphere, a test to determine whether future astronauts could generate their own breathing air, water and rocket fuel from natural resources at the red planet.<\/p>\n

Mars 2020 will also collect rock samples and store them inside sealed tubes for retrieval by a future mission that will return them to Earth.<\/p>\n
