The latest spacecraft news can be found on the mission update page. There are additional scheduled playbacks of the data from MRO and MAVEN, as well as additional orbiter overflights, after landing, that can relay signals from the rover. Since the rover has preprogrammed landing instructions and significant autonomy, Perseverance can land safely on Mars without a communications link.
Both orbiters send data back through the antennas of NASA’s Deep Space Network (DSN). MAVEN, however, will only be able to transmit its data hours after the rover lands. MAVEN will also be flying over Perseverance’s landing site around the same time, recording the same data as MRO. MRO is expected to relay detailed Perseverance engineering data to Earth in near-real-time. Two NASA Mars orbiters will relay data on the Perseverance Mars rover landing back to Earth – the Mars Reconnaissance Orbiter (MRO) and the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft. Perseverance will land with NASA’s Ingenuity Mars Helicopter attached to its belly. The spacecraft is expected to hit the top of the Martian atmosphere at around 3:48 p.m. At that time, they will have effectively taken their hands “off the wheel,” leaving Perseverance to complete the programmed landing sequence on its own. In the next several minutes, mission controllers are expected to turn off the transmitter sending commands to the spacecraft.

Live coverage of NASA’s Mars 2020 Perseverance rover landing is about to start on NASA TV and YouTube. Hundreds of critical events in the rover’s Entry, Descent, and Landing sequence must execute perfectly and exactly on time for the rover to touch down on Mars safely on Feb. This illustration shows NASA’s Perseverance rover casting off its spacecraft’s cruise stage, minutes before entering the Martian atmosphere. The latest spacecraft status can be found on the mission update page. More information about how to watch these streams is on the mission’s watch online page. NASA is currently hosting live coverage of landing on NASA TV and YouTube. ” Not only is the choreography of EDL complex, but the time delay involved in communicating with Earth means that the spacecraft has to accomplish this choreography all by itself. Many engineers refer to the time it takes to land on Mars as the “ seven minutes of terror. The team of engineers that piloted NASA’s Mars 2020 spacecraft, with the Perseverance rover and NASA’s Ingenuity Mars Helicopter inside, during the cruise from Earth to the Red Planet has handed over the reins to the entry, descent, and landing (EDL) team. Hundreds of critical events must execute perfectly and exactly on time for the rover to land on Mars safely on Feb. In this illustration of its descent to Mars, the spacecraft containing NASA’s Perseverance rover slows down using the drag generated by its motion in the Martian atmosphere.
