![]() The results of Solar Orbiter’s observations should provide better forecast of solar flare endangering satellites and telecommunication networks. EREMS provided a High Voltage Power Supply (HPVS) for the SO-PHI instrument. In particular, the probe will use PHI (Polarimetric and Helioseismic Imager) which is a device equipped with two-telescopes providing maps of the magnetic vector and of the line-of-sight (LOS) velocity in the solar photosphere. EUI: Extreme Ultraviolet Imager Metis PHI: Polarimetric and Helioseismic Imager SoloHI: Solar Orbiter Heliospheric Imager SPICE: Spectral Imaging of the. The Polarimetric and Helioseismic Imager instrument (PHI) is one of the six imaging instrument on Solar Orbiter. In order to carry out its mission, Solar Orbiter features 10 instruments allowing the acquisition of data of the Sun’s surface and the formation of solar winds. Mercury is starkly dark against the solar disk, so an ideal instrument shouldn’t get any signals from it. This means that many more active regions will be used in the future to calibrate the helioseismic far-side maps, and study the emergence and evolution of. Image Credit: ESA & NASA/Solar Orbiter/PHI Team. ESA and NASA expect Solar Orbiter to observe solar spots, solar winds and the solar corona for at least 7 years. BBC Science Correspondent New pictures of the Sun taken just 77 million km (48 million miles) from its surface are the closest ever acquired by cameras. Solar Orbiter has entered its nominal mission phase, and the SO/PHI synoptic program will provide magnetograms of the Sun from various vantage points with a cadence of multiple images per day. Although far from the Parker probe’s record with only 19 million kilometers away from the sun, Solar Probe will be facing extreme temperatures up to 600 ☌. The broad outline of Solar Orbiter’s missionĪfter a 2 year long space journey, Solar Orbiter will be place into an orbit allowing it to graviate within 42 million kilometers of the Sun, closer than Mercure.
