The Future of Solar Observations: SPHEREx, PUNCH and Beyond
In the grand arena of scientific discovery, exploration of our Sun has always been limitless. The innovative missions SPHEREx and PUNCH are at the forefront, poised to revolutionize solar observations and deepen our understanding of the solar atmosphere and solar wind. Let’s delve into the fascinating details.
Understanding the SPHEREx Mission
SPHEREx, short for Spectrum-Hydrograph Elevational and Radiative, is equipped with advanced technology that will catapult solar research into a new era.
Equipment and Objective
- Coronagraph: The satellite will carry a coronagraph, specifically designed to capture the outer solar atmosphere, enabling deep study of solar plasma structures.
- Polarization Filters: Each satellite is outfitted with three polarization filters, akin to how polarized sunglasses block specific light waves, enabling precision measurement of polarization. By studying polarized light, researchers can determine the three-dimensional speed, direction, and intensity of solar events as they move away from the Sun.
These tools collectively help solar physicists comprehend crucial aspects, like boundaries and the dynamics of solar winds.
Observing and Forecasting Coronal Mass Ejections
Predicting the potential effects of coronal mass ejections (CMEs) on Earth’s power grids, communication systems, navigation satellites, and even northern lights will be more accurate than ever. This requires precise observation and mapping of these large expulsions of energy, which can disrupt technologies resulting in everything from energy outages to brilliant auroras.
- Spatial Wind Observation: With a camera that captures a broad view of the solar wind, the satellites can track the hot plasma ejected from the solar corona.
Maintaining presence in selected earth orbits, the satellites positioned in synchronous solar orbits perfect for observing the sun avoiding disturbing infrared radiation.
This comprehensive data collection will help create forecast models to predict potential effects of space weather on our technological infrastructure.
Relatedly, SPHEREx and the group will orbit at about 400 miles, aligning equations to the terminator — the boundary that constitutes earth day and night, rotating throughout the north and south poles. Known as a synchronous solar orbit, it ensures that the spacecraft continually maintains its orientation relative to the sun.
This orbital advantage allows for an uninterrupted view at any given time for SPHEREx and clean view of space and beyond avoiding signal interference from local stars providing remarkable observation conditions for furthering our understanding of our galaxy.

Did You Know?
The Sun, our local star, releases vast amounts of energy that impact everything from electronics to planet Earth’s atmosphere in complex and mesmerizing ways.
Experts have managed to gather data on multiple satellites through the phenomenon of coronal mass eclipses, here is an example of it. During a 2012 Solar flare face, solar physicists received information that the CME propagated almost 4 million km before eventually hitting Earth 17 hours later.
While solar observatory research has long been at the forefront of scientific exploration and now with more sophistication on forecasting monuments solar energy releases SPHEREx and PUNCH pride themselves on positioning themselves towards unting their explicitly all-encompassing abilities.
