VikingMission to MarsNASA's Viking Mission to Mars was composed of two spacecraft,Viking 1 and Viking 2, each consisting of an orbiter and a lander.The primary mission objectives were to obtain high resolution imagesof the Martian surface, characterize the structure and composition ofthe atmosphere and surface, and search for evidence of life. Viking 1was launched on August 20, 1975 and arrived at Mars on June 19, 1976.The first month of orbit was devoted to imaging the surface to findappropriate landing sites for the Viking Landers. On July 20, 1976the Viking 1 Lander separated from the Orbiter and touched down at ChrysePlanitia (22.27 N, 312.05 E, planetocentric). Viking 2 was launched September 9, 1975and entered Mars orbit on August 7, 1976. The Viking 2 Lander toucheddown at Utopia Planitia (47.64 N, 134.29 E, planetocentric) on September 3, 1976. TheOrbiters imaged the entire surface of Mars at a resolution of 150 to300 meters, and selected areas at 8 meters. The lowest periapsisaltitude for both Orbiters was 300 km. The Viking 2 Orbiter was powereddown on July 25, 1978 after 706 orbits, and the Viking 1 Orbiter on August17, 1980, after over 1400 orbits. The Viking Landers transmittedimages of the surface, took surface samples and analyzed them forcomposition and signs of life, studied atmospheric composition andmeteorology, and deployed seismometers. The Viking 2 Lander endedcommunications on April 11, 1980, and the Viking 1 Lander on November 13,1982, after transmitting over 1400 images of the two sites. Many ofthese images are also available from NSSDCA online and as photographic products.

The results from the Viking experiments gave our most completeview of Mars. Volcanoes, lava plains, immense canyons,cratered areas, wind-formed features, and evidence of surface waterare apparent in the Orbiter images. The planet appears to bedivisible into two main regions, northern low plains and southerncratered highlands. Superimposed on these regions are the Tharsis andElysium bulges, which are high-standing volcanic areas, and VallesMarineris, a system of giant canyons near the equator. The surfacematerial at both landing sites can best be characterized as iron-rich clay.Measured temperatures at the landing sites ranged from 150 to 250 K,with a variation over a given day of 35 to 50 K. Seasonal dust storms,pressure changes, and transport of atmospheric gases between the polar caps were observed. The biology experiment produced no definitive evidence of life at either landing site.

Further information on the spacecraft, experiments, and data returned from the Viking missions can be found in the September 30, 1977 issue of the Journal of Geophysical Research, "Scientific Results of the Viking Project", vol. 82, no. 28.

Specially designed virtual exhibits allow online visitors to explore the Viking Mission Museum exhibit, curated by experts at VMMEPP and original Viking Team Members. The digital exhibition introduces the story of Viking, the first Mars mission to successfully land on the Red Planet and send images and data back to Earth. In the coming months, VMMEPP will launch additional exhibits covering engineering details, the personal experiences of Vikings, and all the images from the mission including many not previously shared with the public.

The White House Approval document is an item that literally made the mission possible. This little known requirement, approving launch of the radioisotope thermoelectric generator which provided power to the lander, was a major go no go item for the mission and could only be approved by the White House.

The Azimuth Notebooks are hand assembled, spliced and taped notebooks of the surface images and azimuth charts by the Imaging team. They were used to plan the Viking surface images, so that Teams could decide on the next image sets for science and mission purposes such as soil sample locations for the biology, chemistry, and x-ray fluorescence tests; to check instruments; for USGS to survey the surface environment; and more.

The complete set of Communications Bulletins act as the timeline guiding viewers from pre-launch, through Mission Operations up until the Landing and first images, and include historic moments and aerospace firsts.

This Exhibit is the first of many to come, by The Viking Mars Missions Education & Preservation Project 501(c)3, on the GCI platform, which will share publicly the results of ongoing restoration, curation, and educationally oriented, technically deep presentation of the Viking Mars Missions. It provides samples of the events, artifacts, and human experience that made this Mars mission happen, covering the timeline from conception through launch to landing and science. It will also feature special works by Vikings and those influenced by the mission, such as never before seen reprocessed images by Olivier De Goursac, a young Viking intern from France who worked on the mission at JPL during Mission Operations.

The Viking Mars Mission Education and Preservation Project (VMMEPP) is a 501(c)3 non-profit organization dedicated to collecting and curating the artifacts and team recollections of NASA's Viking Mars Mission, with the support of the Viking Project Office team and Viking team members form around the world. VMMEPP applies this collection to create interactive educational exhibits, both virtual and physical, for the purpose of inspiring future leaders and thinkers.

No known strategies can get rid of the time lag in communications between Earth and Mars; a message moving at the speed of light takes anywhere between four and 24 minutes for a one-way trip. In other words, a quick ping to mission control is out of the question, not to mention a WhatsApp call home.

Perseverance and other Mars rovers get most commands directly from Earth via X band radio waves. Though Percy can send small amounts of data directly, it often uses ultrahigh-frequency, or UHF, radio waves to transmit data to one of the orbiters in the Mars Relay Network, which have big antennas for sending data to Earth. Percy also served as a base station for communication with the helicopter Ingenuity.

Though traditional radio frequencies would suffice for low data rates, using a laser link could carry 10 to 100 times as much data in the same time frame. Because of the higher frequencies of optical waves, hundreds of thousands of times those of radio waves, much more information can be packed in. Thus, this type of optical signal is just where space communication may be headed.

ESA is also exploring long-distance optical communication. One program called ScyLight, short for Secure and Laser Communication Technology and pronounced skylight, is supporting the research and development of optical and quantum technologies for secure and fast data communication from space.

Most of us here on Earth access the internet through our phones using radio-frequency radiation on either wireless 4G or 5G networks or through Wi-Fi routers. These connections are linked via fiber-optic cables around the world. The proposed Mars network would instead be similar to Starlink, a constellation of satellites in low Earth orbit operated by SpaceX. On Earth, broadband internet and mobile phone coverage via satellite is expensive, but on Mars, such a system might be cheaper and easier to build than an expansive and robust network on the ground.
