Visa Mars measuring 10 anniversary
Visa Mars measuring 10 anniversary
Decades to collect accurate measurement data itself is a feat, with the help of the probe in140 million milesOutside of a desolate planet surface it devilishly hard to finish this task is.
And this feat is real happened.NASA's Mars science laboratory (MSL) curiosity landing on Mars in August 2012.Since then, curiosity Mars continues to collect environmental measuring data, the findings by scientists around the world overflow.
The environmental conditions on Mars is very challenging, Mars probe of some mechanical parts have been showing signs of wear and tear, but measuring sensor is still strong as before, to provide the data, far more than the initial mission objectives for two years.Which is more important is the humidity and air pressure measurement, the parameters provided by the Finnish meteorological institute (FMI) pick up visa measurement technology of sensor measurements.
Dusty and cold on Mars, the atmosphere is very thin.Records show that the average temperature is about 63 ° C - Mars surface, but in the daytime temperatures of up to + 35 ° C.From the point of view of research, Mars provides a better understanding of the evolution of earth and its future trends.If Mars and earth billions of years ago, for example, are both wet and warm, why the two very different now?
Curiosity Mars is moving and ACTS as a station in multiple locations.In addition, NASA's new Mars rover "perseverance" is also on the surface of Mars, carrying a similar visa measurement technology.The two rovers are about 2000 km apart, its measurement observation network laid the foundation for building the Martian atmosphere is to better understand and predict weather is an indispensable part of Mars.
Sensor performance is good!
On the NASA probe sensor during flight and explore the planet's surface is in very bad conditions.In addition to the great changes in temperature and pressure, thick dust sensor must also be tolerance and very high levels of vibration.
Visa number of curiosity and perseverance on pressure sensors on the slight modification to adapt to the Mars extremely low range, in addition, the two car Mars deployment of measurement technology and daily use multiple industry on the planet are basically the same.
Visa continued investment in product development and research, and is committed to innovation and development of measurement technology.Good sensor performance from our internal professional knowledge and experience of scientific curiosity and support.
