In a monumental effort to combat climate changethe British startup Satellite Vu He has launched HotSat-1the first satellite capable of measuring the heat emission of any building on our planet.

HotSat-1: A thermometer 500 km high

This pioneer “thermometer in the sky” it has the ability to individually observe roofs and walls from an altitude of 500 km thanks to its advanced infrared sensor. The resolution and precision of this sensor will make it possible to accurately identify the most and least efficient buildings in terms of heat emission.

A crucial role in climate change mitigation

The information collected by HotSat-1 will have significant implications in the global fight against climate change. Detailed data on the thermal efficiency of buildings will allow governments and companies to direct their efforts and resources towards those buildings that need to be retrofitted or renovated to reduce their heat emissions and therefore their carbon footprint. This modernization of the infrastructures could be a key element to reach the goals of net zero emissions.

Detecting urban heat islands

In addition to measuring heat emissions from buildings, HotSat-1 has the ability to identify structures and open spaces that contribute to the phenomenon known as urban heat island effect. This phenomenon occurs when certain urban areas heat up significantly more than the surrounding rural areas due to the concentration of buildings and the scarcity of vegetation. The satellite can help plan solutions to minimize this effect, such as strategic tree planting.

Beyond buildings: monitoring pollution and thermal changes in rivers

He HotSat-1 You are not only limited to observing buildings. It can also be used to monitor pollution and detect sudden changes in river temperatures, providing crucial information for environmental protection and public health.

Future tests and applications

The data of the HotSat-1 have already been tested over the borough of Ealing in London, with the British national mapping agency, Ordnance Survey (OS), monitoring data collection. OS plans to use this data to create more accurate and detailed maps and reports, which will prove very useful in various industries.

There is no doubt that initiatives like this, which combine cutting-edge space technology with the aim of combating climate change, represent an important step in the right direction. The innovation and ingenuity demonstrated by Satellite Vu with HotSat-1 reminds us that when it comes to protecting our planet, the sky is not the limit, but rather a new horizon to explore.
