This illustration shows a conceptual design of a Mars Science Helicopter, a proposed follow-on to NASA's Ingenuity Mars Helicopter. Researchers are considering how helicopters could be used in future missions. In addition to scouting, such a helicopter could carry science instruments to study terrain rovers can't reach. The proposed design is the product of collaboration between NASA's Jet Propulsion Laboratory in Southern California, NASA's Ames Research Center in Silicon Valley, and AeroVironment, Inc. A helicopter with this particular design could carry 4.5 to 11 pounds (2-5 kilograms) of science payload. https://photojournal.jpl.nasa.gov/catalog/PIA24729

A model of NASA's Mars Science Helicopter concept is shown in this photo. This helicopter concept is a more capable proposed follow-on to NASA's Ingenuity Mars Helicopter, which arrived at the Red Planet in the belly of the agency's Perseverance rover in February 2021. The six-rotor Mars Science Helicopter could be used during future Mars missions to serve as an aerial scout, carrying between 4.5 and 11 pounds (2 to 5 kilograms) of payload, including science instruments, and studying terrain that rovers can't reach. It remains in early conceptual and design stages.

This illustration shows the proposed process for safely recovering, containing, and transporting Mars samples gathered by NASA's Perseverance Mars rover after they are returned to Earth as part of the joint NASA/ESA (European Space Agency) Mars Sample Return Campaign. The process of carefully containing and handling the samples would begin long before they arrive on Earth. Every phase of the Mars Sample Return campaign from collection and sealing to launch, transfer, and landing has been developed with a "safety first" approach. Sample handling and curation experts would be involved in planning for the round trip at each phase of the campaign. After its journey back to Earth from Mars on the ESA-provided Earth Return Orbiter, the capsule containing the samples would land at the Utah Test and Training Range in west-central Utah. NASA would securely transport the capsule and its contents to a Sample Return Facility at a location to be determined. Once at the facility, the samples would undergo a rigorous process to assess whether they are safe for release for detailed analysis by scientists from around the world. https://photojournal.jpl.nasa.gov/catalog/PIA25857

This animation shows the position of NASA's Perseverance Mars rover as of Dec. 4, 2024, the 1,347th Martian day, or sol, of the mission, along with the proposed route of the mission's fifth science campaign, dubbed Northern Rim, over the next several years. This map was made using data from NASA's Mars Reconnaissance Orbiter's High-Resolution Imaging Science Experiment (HiRISE) camera as well as the European Space Agency's (ESA) High Resolution Stereo Camera (HRSC). The University of Arizona, in Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., in Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA's Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

NASA's Mars Chopper concept, shown in a design software rendering, is a more capable proposed follow-on to the agency's Ingenuity Mars Helicopter, which arrived at the Red Planet in the belly of the Perseverance rover in February 2021.

It could be used to carry science payloads as large as 11 pounds (5 kilograms) distances of up to 1.9 miles (3 kilometers) each Martian day (or sol). Scientists could use Chopper to study large swaths of terrain in detail, quickly – including areas where rovers cannot safely travel. Chopper remains in early conceptual and design stages. The proposed design is the product of collaboration between NASA's Jet Propulsion Laboratory in Southern California, the agency's Ames Research Center in California's Silicon Valley, and AeroVironment Inc. https://photojournal.jpl.nasa.gov/catalog/PIA26375

This chart describes the Skylab student experiment Motor Sensory Performance, proposed by Kathy L. Jackson of Houston, Texas. Her proposal was a very simple but effective test to measure the potential degradation of man's motor-sensory skills while weightless. Without knowing whether or not man can retain a high level of competency in the performance of various tasks after long exposure to weightlessness, this capability could not be fully known. Skylab, with its long-duration missions, provided an ideal testing situation. The experiment Kathy Jackson proposed was similar in application to the tasks involved in docking one spacecraft to another using manual control. It required one of the greatest tests of the motor-sensory capabilities of man. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.

One of the most successful of the Skylab educational efforts was the Skylab Student Project. This was a nationwide contest in which secondary school students submitted proposals for experiments to fly on Skylab. After the official announcement of this project, over 4,000 students responded with 3,409 proposals from which 25 winners were selected. In the subsequent evaluation of these 25 proposed experiments in terms of their suitability for flight, the Marshall Space Flight Center, the lead center for Skylab, selected 19. This photograph is a group shot of the 25 winners in the Skylab student program when they met for the first time at the Marshall Space Flight Center in May 1972.
