ESA spacecraft records crucial NASA signals from Mars ESA

ESA’s Mars Express acquired signals from NASA’s Mars Science Laboratory as it delivered the car-sized Curiosity rover onto the Red planet’s surface. ESA’s New Norcia tracking station also picked up signals directly from the NASA mission, 248 million km away at Mars.
A key step was completed today in ESA’s ongoing support to NASA’s Mars Science Laboratory (MSL) mission. Signals recorded by Mars Express during MSL’s entry and descent were successfully received at ESOC, ESA’s European Space Operations Centre, Darmstadt, Germany.
The open-loop recording of radio Doppler and signal spectrum transmitted by the NASA mission were stored on Mars Express and then downloaded to Earth.
