In line with this unpleasant year, which is 2020, yesterday’s launch of NASA’s Mars endurance is the rover was not without problems.
As planned, the ULA Atlas V rocket with the rocket endurance rover a ingenuity helicopter lifted lähde: Cape Canaveral Air Force Sin Florida yesterday morning, The Mars 2020 mission is now expected to reach the Red Planet in February 2021.
Everything looked like a picture perfect, but NASA said a few unusual things happened during the launch that were not expected to jeopardize the mission.
When the Atlas V turned space, telemetry signals transmitted to terrestrial antennas were unable to receive incoming data. The spaceship was obviously too close to NASA’s Deep Space Network – a system of terrestrial antennas designed to communicate in deep space – causing signal saturation on terrestrial receivers, which, according to NASA, prevented the proper reception of telemetry data.
“This is a known issue we have encountered in other planetary missions, including during the launch of NASA curiosities in 2011,” explained Matt Wallace, deputy project manager for Mars 2020 at NASA. statement, “The perseverance team worked on prepared mitigation strategies that included detecting the receivers and directing the antennas slightly off target from the spacecraft to bring the signal to an acceptable range. After completing these steps, we are now locked in telemetry. ”
Okay, so no big deal, but the second edition, though not serious, is still underway: The spacecraft is currently in safe mode after a temperature anomaly.
The system uses a liquid Freon loop in which heat from the spacecraft’s core is transferred to radiators on a cruise platform, which is the part of the vehicle that delivers the rover to Mars. A sizthe capable temperature gap between the hot inlet to the radiators and the radiator outlet from the radiators led to a preventive software mode.
“When the spaceship entered the shadow of the Earth, the Sun was temporarily blocked by the Earth and the ascent temperature dropped,” Wallace said. “This caused the difference between the heat input and the radiator output to increase. This transient differential triggered an alarm and caused the spacecraft to go into a standby mode known as “safe mode.” ‘ “
Wallace called it a “transient event,” saying that launching safe mode “during this transitional phase is not problematic for Mars 2020.”
NASA says it has a management problem, and control missions are now taking the necessary steps to bring the spacecraft back to normal travel.
Phew. I’m glad these are minor issues. The main obstacle to the Mars 2020 mission is exactly what we do not need at the moment.
