What is MAIA Satellite? Top 10 Facts about NASA's New Project

By Srikanto Mandal 9 March, 2023

NASA and the Italian Space Agency (ASI) have partnered to develop a satellite called the Multi-Angle Imager for Aerosols (MAIA).

The mission aims to analyze the impact of airborne particle pollution on human health by collecting and processing data from the observatory, ground sensors, and atmospheric models

Epidemiologists and public health researchers have been directly involved in the development of the MAIA mission.

MAIA will focus on 11 primary target areas that cover major urban centers around the world, including Los Angeles, Atlanta ....

and Boston in the United States; Rome; Addis Ababa, Ethiopia; Barcelona, Spain; Beijing; Johannesburg; New Delhi; Taipei, Taiwan; and Tel Aviv, Israel.

Airborne particle pollution has been linked to respiratory diseases, cardiovascular diseases, and adverse reproductive and birth outcomes.

The MAIA mission's main objective is to study whether exposures to different types of particle pollution have differing health impacts.

Over the course of its three-year mission, MAIA will also collect data on short-term exposure to particulate pollution, chronic exposure, and sub-chronic exposure.

MAIA's measurements of sunlight reflecting off airborne particles will help researchers determine the abundance, size, and optical properties of certain pollutants in the atmosphere.

The MAIA observatory will consist of a satellite provided by ASI and a science instrument built at NASA's Jet Propulsion Laboratory in Southern California.

The MAIA mission is set to launch before the end of 2024 and continues decades of collaboration between NASA and ASI, including on the Cassini mission to Saturn.
