Unveiling the Secrets of the Sun: Nasa’s PUNCH Mission to Image Sun’s Atmosphere, Track Origins of Solar Winds | Technology News
Introduction
As the Earth’s magnetic field provides a shield against solar radiation, it is essential to have a comprehensive understanding of solar winds and Coronal Mass Ejections (CMEs). The Polarimetry to Unify the Corona and Heliosphere (PUNCH) mission, launched by Nasa and set to take off on February 28, 2023, will revolutionize our understanding of the solar atmosphere and its dynamics.
A New Era in Solar Research
The PUNCH mission marks a new era in solar research, as it will be the first to use polarimetry to measure the sun’s corona and solar wind in 3D. The mission’s primary objective is to reconstruct the formation, trace the origins, and map the evolution of solar winds and CMEs, which significantly impact space weather and have a direct effect on Earth’s satellite-based communication services, GPS-based navigation, and power grid operations.
A Suite of Four, Suitcase-Sized Satellites
The PUNCH mission will consist of four suitcase-sized satellites, each weighing around 64 kg, sent to the Low Earth Orbit (LEO). The mission is expected to last for two years, providing a constant stream of data and insights into the solar atmosphere.
How PUNCH Will Achieve Its Objectives
The PUNCH mission will employ a unique, single, virtual instrument to generate large-scale imagery data, creating a 3D image of the solar corona. The mission’s wide field of view will allow it to continuously image the sun’s corona, using four onboard cameras to capture high-resolution images of the outer atmosphere.
The Science Behind PUNCH
The mission’s success relies on the principle of light polarization. When electrons, scattered sunlight, and waves of light align, they create polarized light, which PUNCH will measure using polarizing filters. This will allow scientists to look into the inner solar system, gaining valuable insights into the formation of CMEs and solar winds.
Unraveling the Mysteries of the Solar Corona
The PUNCH mission will help scientists unravel the mysteries of the solar corona, understanding the sun’s atmosphere transition to solar wind and the forces that act upon the corona. By studying the solar wind and CMEs, scientists can better predict space weather and its impact on humanity’s robotic explorers in space.
Expert Insights
"Dibyendu Nandi, a solar physicist at the Indian Institute of Science Education and Research, Kolkata, notes, "With PUNCH, we will be able to see where the CMEs and solar winds are formed, how they evolve and get accelerated, and try to pin down on the forces or energies that help them gain speeds and ultimately, how they evolve through the interplanetary space. All this is important for timely prediction of space weather."
Conclusion
The PUNCH mission represents a significant step forward in our understanding of the sun’s atmosphere and its impact on space weather. With its unique polarimetry capabilities, PUNCH will provide scientists with new information leading to more accurate predictions about the arrival of space weather events on Earth. The mission’s findings will have significant implications for satellite-based communication services, GPS-based navigation, and power grid operations, ultimately paving the way for a safer and more reliable space exploration.
