11/25/2023 0 Comments Mars lunar landingThis configuration allows mission controllers to communicate with spacecraft throughout the solar system at all times throughout Earth’s daily rotation. Managed by JPL for NASA’s Space Communications and Navigation program (SCaN), the DSN consists of several parabolic radio antennas at ground stations in Southern California, near Madrid, Spain, and outside Canberra, Australia. ![]() Others use ultra high frequencies (or UHF) to communicate with MRO and MAVEN. Some of these antennas use powerful X-band transmissions that can send small amounts of data directly to the DSN.

This dance will ensure that the world can watch Perseverance’s entry, descent, and landing – a harrowing sequence of events that will begin as the rover’s interplanetary cruise ends.Īntenna for the Deep Space Network: Madrid’s radio antennas will take the lead in receiving telemetry from the Mars Relay Network during Perseverance’s entry, descent and landing. While the choreography of this relay scheme is now somewhat commonplace for assets in place, it is still extremely challenging to coordinate all the communication links for the very brief time during a lander’s arrival.” “Since Mars Global Surveyor (MGS) arrived in orbit in 1997, a steady stream of orbiters has been added, carrying relay radios and antennas, which provide highly efficient communications between surface landers and Earth. “It is a huge endeavor to maintain communications with our spacecraft throughout the solar system, but Mars surface missions take this commitment to another level,” said Bradford Arnold, DSN project manager at NASA’s Jet Propulsion Laboratory in Southern California. Most data traveling back to Earth must first be sent to the Mars orbiters overhead, which then transmit the data tens of millions of miles through interplanetary space to radio antennas on Earth, including the antennas of NASA’s venerable Deep Space Network (DSN). While some commands and telemetry can be sent directly to and from Earth, for the most part, the huge quantities of science data collected by rovers and landers cannot, because it would take too long. ![]() NASA’s Mars Reconnaissance Orbiter ( MRO) and the Mars Atmospheric and Volatile EvolutioN ( MAVEN) orbiter are a part of the Mars Relay Network, a constellation of spacecraft that serves as a lifeline to the current surface missions on Mars – NASA’s Curiosity rover and InSight lander. ![]() From orbit, two robotic buddies will be playing a special role in the event by checking in on the mission’s vital signs from the moment Perseverance enters the atmosphere to long after it makes its first tracks on the Martian surface. When NASA’s Mars 2020 Perseverance rover touches down with the Ingenuity Mars Helicopter on the Red Planet on Feb. A tightly choreographed dance between NASA’s Deep Space Network and Mars orbiters will keep the agency’s Perseverance in touch with Earth during landing and beyond.
