The chief pilot for NASA's Ingenuity Mars Helicopter, Håvard Grip, speaks at the Robert J. Collier Dinner in Washington on June 9, 2022. The Ingenuity Mars Helicopter team was awarded the 2021 Collier Trophy "for the first powered, controlled flight of an aircraft on another planet, thereby opening the skies of Mars and other worlds for future scientific discovery and exploration," the award citation states. This historic trophy – which is on permanent display at the Smithsonian Air and Space Museum in Washington – is awarded annually by the National Aeronautic Association "for the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year." https://photojournal.jpl.nasa.gov/catalog/PIA25216

In the Kennedy Space Center’s Operations Support Building II, Dr. Eugene Parker, a pioneer in heliophysics and S. Chandrasekhar distinguished service professor emeritus for the Department of Astronomy and Astrophysics at the University of Chicago, speaks to members of news and social media in a prelaunch mission briefing about NASA's Parker Solar Probe on Thursday, Aug. 9, 2018. The spacecraft is designed to provide key observations on his groundbreaking theories about the Sun. This is the first NASA mission named for a living person. Lift off atop a United Launch Alliance Delta IV Heavy rocket will take place from Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida. The spacecraft was built by Applied Physics Laboratory of Johns Hopkins University in Laurel, Maryland. The mission will perform the closest-ever observations of a star when it travels through the Sun's atmosphere, called the corona. The probe will rely on measurements and imaging to revolutionize our understanding of the corona and the Sun-Earth connection.

This chart illustrates how NASA Curiosity rover talks to Earth. While the rover can send direct messages, it communicates more efficiently with the help of spacecraft in orbit, including NASA Odyssey and MRO, and European Space Agency Mars Express.

This frame from an artist animation depicts how NASA Curiosity rover will communicate with Earth during landing. As the rover descends to Mars, it will send out basic radio-frequency tones that go directly to Earth.

This chart shows increases in the volume of data coming back from NASA Mars Curiosity over recent sols. New capabilities of the Electra relay-radios on MRO and Curiosity have greatly increased the volume of data the rover is sending back from Mars.
