NASA’s Close to House Community permits spacecraft exploring the photo voltaic system and Earth to ship again important science information for researchers and scientists to analyze and make profound discoveries.
Now, the community has built-in 4 new world antennas to additional help science and exploration missions. In December 2022, antennas in Fairbanks, Alaska; Wallops Island, Virginia; Punta Arenas, Chile; and Svalbard, Norway went on-line to supply current and future missions with S-, X-, and Ka-band communications capabilities.
These new antennas have been created to help missions capturing immense quantities of information. Simply as scientists enhance their instrument capabilities, NASA additionally advances its communications methods to allow missions near-Earth and in deep area.
This improve is bringing unprecedented flexibility to the Close to House Community and can improve direct-to-Earth communications – the method by which a satellite tv for pc takes an image after which sends the picture over radio waves to an antenna on Earth. This information is then processed and despatched to scientists. The Close to House Community is managed by NASA’s House Communications and Navigation (SCaN) program workplace, which oversees improvement and enhancement of NASA’s two major communications networks: the Close to House and Deep House networks.
The Close to House Community offers missions with communications providers by a mix of government-owned and industrial belongings. To develop these new antennas, the workforce labored with industrial accomplice Kongsberg Satellite tv for pc Providers (KSAT), who created the Chile and Norway antennas, whereas NASA developed the opposite two in Virginia and Alaska.
Now operational, the 4 antennas are built-in into the community’s service catalog, advancing its capabilities to help science and exploration missions that use enhanced instrumentation. Now, missions utilizing the community will be capable to ship again terabytes of information for processing and discovery.
An instance is the upcoming Plankton, Aerosol, Clouds, ocean Ecosystem (PACE) mission, which can assist researchers higher perceive ocean ecosystems and carbon biking and reveal how aerosols would possibly gasoline phytoplankton progress on the ocean’s floor.
“Missions just like the PACE satellite tv for pc incorporate high-resolution science devices,” mentioned Damaris Guevara, mission lead for the networking improve. “These devices require superior area communications capabilities, like Ka-band, to get the whole lot of their information again to Earth.”
The brand new antennas additionally can have new networking capabilities.
All 4 floor stations are incorporating Delay/Disruption Tolerant Networking (DTN). DTN will empower missions with unparalleled connectivity by storing and forwarding information at factors alongside the community to make sure vital info reaches its vacation spot. DTN is a complicated communications functionality being developed and examined by NASA’s SCaN and House Expertise Mission Directorate.
Moreover, to boost mission groups’ entry to information, the community incorporates cloud-based information storage providers. Satellites like PACE will downlink their information to an antenna, and that information will undergo the bottom station’s high-rate information processors to a cloud-based storage and information entry service that may permit mission groups to amass their information sooner and from nearly wherever. This reduces {hardware} wants and lowers general storage prices.
A number of missions will profit from this new infrastructure and superior capabilities, together with the NASA-Indian House Analysis Group Artificial Aperture Radar (NISAR) satellite tv for pc. Launching in 2024, NISAR will measure Earth’s altering ecosystems, dynamic surfaces, ice plenty, and extra.
With 4 new antennas across the globe, the Close to House Community is advancing its capabilities to help science and exploration missions that use enhanced instrumentation. Now, missions utilizing the community will be capable to ship again terabytes of information for processing and discovery.

Deep-space optical communication demonstration project forges ahead
Washington DC (SPX) Dec 09, 2022
Researchers report new outcomes from the NASA Deep House Optical Communications (DSOC) know-how demonstration mission, which develops and exams new superior laser sources for deep-space optical communication. The flexibility to carry out free-space optical communication all through the photo voltaic system would transcend the capabilities of the radio communication methods used now and supply the bandwidth obligatory for future area missions to transmit massive quantities of information, together with high-definition photographs and vid … read more
