NASA satellites, regardless of the vacation spot, have to speak their information to mission management and scientists on Earth. These missions seize extraordinary information that make communications a necessary a part of every mission: photos of galaxies, essential data on photo voltaic flares and rather more. An interactive on-line device now exhibits reside information transmissions from every of NASA’s three house communications networks and the missions supported by these information.
NASA’s three house communications networks – the Deep Area Community (DSN), the Close to Earth Community (NEN) and the Area Community (SN) – present radio frequency communications for all NASA missions, together with the upcoming 2024 Artemis missions to the Moon, in addition to missions for different authorities companies and industrial companions.
To showcase real-time information flowing by way of these networks, the Area Communications and Navigation (SCaN) program workplace created SCaN Now, an interactive on-line platform the place guests can find out about NASA’s house communications infrastructure, information transmission and network-supported missions. On Dec. 5, the SCaN Now web site debuted SN Now as an addition to the preliminary choices of DSN Now and NEN Now, which allowed guests to browse NEN and DSN supported satellites and witness reside information transmissions to and from floor stations across the globe.
The SN Now platform presents variations from the earlier merchandise. Each the DSN and NEN present direct-to-Earth communications for satellites, that means when a satellite tv for pc enters an antenna’s line of sight, it transmits information. To indicate this within the on-line product, the energetic antenna lights up and shows which mission is at the moment speaking. Whereas these platforms spotlight direct-to-Earth communications, SN Now highlights NASA’s space-to-space relay system.
Spacecraft supported by the SN, together with the Worldwide Area Station, don’t have to have line of sight with a floor station. As an alternative, they contact one of many SN’s 10 Monitoring and Information Relay Satellites (TDRS), which relays the information to Earth. This relay system offers missions with dependable, close to steady protection, and permits astronauts to have fixed communications with each mission management and their households.
With the brand new SN Now platform, guests can witness reside information transmissions from a mission to a TDRS and find out about that mission. For instance, guests can see information flowing from the house station to a TDRS. Typically, SN Now guests will see two TDRS lit up and receiving information from the station. This allows steady information protection with no gaps. With station missions, NASA should be certain that all information is communicated to mission management on Earth.
“After we developed NEN Now, we constructed it round a versatile, expandable structure as a result of we’re at all times serious about the longer term,” stated Ryan Turner, SCaN Now mission supervisor. “That method made it doable for us to spin off SCaN Now comparatively shortly. Now we’re in a position to launch SN Now so as to add to SCaN’s outreach portfolio and full the real-time standing shows of SCaN’s networks.”
Whereas SCaN Now has all three networks built-in into one cohesive product, innovation doesn’t cease right here. Updates to your entire SCaN Now platform will proceed as new missions are added and new web site capabilities are developed.
This device is a novel solution to educate college students and the general public about radio frequency house communications. Because the company’s Artemis program goes ahead to the Moon, college students will be capable to see real-time communications from the Moon to Earth by way of one of many SCaN Now networks.
The SCaN program workplace oversees all of NASA’s house communications actions, together with the ground-based services and companies offered by the DSN, NEN, SN and TDRS.

Cleaning the dishes is a dusty job in outback Australia
New Norcia, Australia (ESA) Nov 28, 2019
Massive antennas are our solely present means of speaking by way of house throughout huge distances, and every so often they have to be spruced up to make sure we will keep up a correspondence with our deep-space exploration spacecraft.
Early this November, ESA’s Deep Area Antenna in New Norcia, Australia, was topic to main upkeep, with a variety of updates applied to maintain it in pristine order.
To speak with ESA’s fleet of spacecraft, the place of the antenna must be managed wi … read more
