What time is expected on Mars for today?


NASA's InSight mission will become the new meteorological service on Mars thanks to a collaboration tool between JPL, Cornell University and the Center of Astrobiology (CAB, CSIC-INTA).

Despite how cold it is It is being winter this year in some areas of our planet, it can not be compared to the glacial cold of Mars. To prove this, the InSight mission will publish a daily meteorological report, providing more information about the time than any previous mission on the Martian surface.

This is a public access tool, jointly developed by JPL, Cornell University and the Center for Astrobiology (CAB, CSIC-INTA ), which will show maximum and minimum temperature, wind speed and direction and air pressure. & nbsp;

All this data is obtained by the meteorological sensor set on board the InSight mission, called the Auxiliary Payload Subsystem (APSS). The lander records this data every second of each sun (Martian day) and sends it to Earth daily. & Nbsp;

For meteorologists, this is going to be a novel experience and, in a way, exciting, since it will be for them the opportunity to study the meteorology of another planet. For Don Banfield, a researcher at Cornell University, who leads the environmental scientific team, "you get the feeling of visiting an alien place. There are familiar phenomena on Mars that are completely different from those that occur on Earth. "& Nbsp;

The continuous measurement of meteorological data will allow scientists to detect sources of what is known as 'instrumental noise' in the measurements that may affect the main scientific instruments of the mission, the seismometer and the heat flux sensor.

For Don Banfield "APSS will help us filter the noise in our data and know when we are seeing an earthquake and when not. " In addition, "by operating continuously, we will have a more detailed view of the time than the rest of the surface missions, which normally collect data for only a few hours of each sun."

InSight will provide a unique set of data that will complement those of other active missions, such as the NASA Curiosity rover and the ships that currently orbit Mars. The InSight temperature and wind sensors (TWINS, Temperature and Wind Sensors for InSight) are actually restored parts, originally built for the Curiosity weather sensors, the Rover Environmental Monitoring Station (REMS). These sensors, located on the deck of the lander in two booms oriented in opposite directions east-west, have been provided by the Center for Astrobiology.

TWINS will be used to know the state of the wind and will allow the mission team to discard unreliable seismic data due to the presence of strong winds. But it can also be used, together with the InSight cameras, to study the amount of dust around the lander. In addition, APSS will help learn more about another little known feature of Mars: the so-called dust devils , small tornadoes that plow through the Martian plains producing patterns of dark lines on the surface of the red planet.
