The National Aeronautics and Space Administration (NASA) is poised to embark on two ambitious flagship missions in the field of heliophysics, following recommendations made by a recent decadal survey. The proposed missions, which have been identified as crucial for advancing our understanding of the Sun and its impact on the solar system, are expected to provide groundbreaking insights into the Sun’s behavior and its effects on the surrounding space environment.
The decadal survey, which is conducted every 10 years, brings together experts in the field of heliophysics to identify the most pressing research questions and recommend the most effective ways to address them. The survey’s recommendations are based on a thorough review of the current state of research in the field, as well as the latest advances in technology and instrumentation.
The two flagship missions recommended by the decadal survey are designed to tackle some of the most fundamental questions in heliophysics, including the Sun’s impact on the solar system, the nature of space weather, and the effects of solar variability on the Earth’s climate. The missions, which are expected to be launched in the mid-2020s, will employ cutting-edge technology and instrumentation to collect unprecedented amounts of data on the Sun and its surroundings.
The first mission, known as the Solar Orbiter Plus, is designed to study the Sun’s polar regions and the solar wind, a stream of charged particles emanating from the Sun. The mission will involve a spacecraft that will be placed in a highly elliptical orbit around the Sun, allowing it to observe the Sun’s polar regions in unprecedented detail. The spacecraft will be equipped with a range of advanced instruments, including a coronagraph, a magnetometer, and a plasma detector, which will enable scientists to study the Sun’s magnetic field, solar wind, and coronal heating.
The second mission, known as the Magnetosphere, Ionosphere, and Solar Wind (MISW) mission, is designed to study the interaction between the solar wind and the Earth’s magnetosphere. The mission will involve a constellation of satellites that will be placed in orbit around the Earth, allowing scientists to study the solar wind and its effects on the Earth’s magnetic field in unprecedented detail. The satellites will be equipped with advanced instruments, including magnetometers, plasma detectors, and spectrometers, which will enable scientists to study the solar wind, the Earth’s magnetic field, and the ionosphere.
Both missions are expected to provide groundbreaking insights into the Sun’s behavior and its effects on the surrounding space environment. The Solar Orbiter Plus mission, for example, is expected to provide unprecedented observations of the Sun’s polar regions, which are thought to play a crucial role in the formation of the solar wind. The MISW mission, on the other hand, is expected to provide unprecedented insights into the interaction between the solar wind and the Earth’s magnetosphere, which is thought to be responsible for a range of space weather phenomena, including geomagnetic storms and aurorae.
The two missions are also expected to have significant implications for our understanding of space weather and its effects on the Earth’s climate. Space weather, which refers to the dynamic and variable conditions in the space environment, can have a significant impact on the Earth’s magnetic field, radiation levels, and upper atmosphere. The Solar Orbiter Plus and MISW missions are expected to provide unprecedented insights into the causes of space weather, allowing scientists to better predict and prepare for space weather events.
In addition to their scientific benefits, the two missions are also expected to have significant technological spin-offs. The advanced instruments and technologies developed for the missions, for example, are expected to have applications in a range of fields, including telecommunications, navigation, and weather forecasting.
The NASA heliophysics decadal survey is a critical component of the agency’s strategic planning process. The survey provides a framework for prioritizing research in the field of heliophysics, and for identifying the most effective ways to address the most pressing research questions. The survey’s recommendations are based on a thorough review of the current state of research in the field, as well as the latest advances in technology and instrumentation.
The decadal survey is conducted by the National Academy of Sciences, in collaboration with NASA and the National Science Foundation. The survey involves a committee of experts in the field of heliophysics, who are tasked with identifying the most pressing research questions and recommending the most effective ways to address them. The committee’s recommendations are based on a thorough review of the current state of research in the field, as well as the latest advances in technology and instrumentation.
In conclusion, the NASA heliophysics decadal survey has recommended two flagship missions that are expected to provide groundbreaking insights into the Sun’s behavior and its effects on the surrounding space environment. The Solar Orbiter Plus and MISW missions are expected to have significant implications for our understanding of space weather and its effects on the Earth’s climate, and are expected to have significant technological spin-offs. The missions are a critical component of NASA’s strategic planning process, and are expected to play a major role in advancing our understanding of the Sun and its impact on the solar system.
