![]() ![]() It will thus probe the deepest layers of the Sun (including the solar interior using helioseismology) of all the instruments on Solar Orbiter or the Inner Heliospheric Sentinels. The Solar Orbiter was approximately halfway between the Earth and Sun when these images were taken, and continues to move closer. Science nugget: An interesting interplanetary shock A particularly interesting aspect of the Solar Orbiter exploration is the possibility to study interplanetary shock waves using datasets previously unavailable in terms of quality and heliocentric distances. PHI will provide maps of the magnetic vector and of the line-of-sight (LOS) velocity in the solar photosphere. Rust and Jacques-Emile Blamont would have been glad that. "We can also see how our ten scientific instruments complement each other, providing a holistic picture of the Sun and the surrounding environment." A famous (l, nu) diagram observed aboard PHI / Solar Orbiter in March 2021. "We didn’t really expect such great results right from the start," said Daniel Müller, ESA’s Solar Orbiter project scientist. The photos it has sent back bode well for the mission's future. ![]() The Solar Orbiter completed its first close pass of the star in June, orbiting 77 million kilometers away - about halfway between us and the Sun. (PHI) is another cutting-edge instrument aboard Solar Orbiter. Carrying six telescopes and four other instruments to monitor the surrounding environment, the spacecraft's mission is to study the Sun, taking measurements to help scientists understand it. Parker Solar Probe’s 16th orbit included a perihelion that brought the spacecraft within 5.3 million miles of the Sun. Solar Orbiter, launched on 10 February 2020, carries six remote-sensing instruments, or telescopes. Launched on February 9, the Solar Orbiter is a joint project by NASA and the European Space Agency. This animation shows a sequence of of images from the Polarimetric and Helioseismic Imager (PHI) on ESA/NASA’s Solar Orbiter. ![]() NASA and the European Space Agency have released the amazing first images taken by the Solar Orbiter - including the closest pictures ever taken of our nearest star. ![]()
