(News from ESA)
Today, June 15, 2020, the ESA/NASA Solar Orbiter spacecraft made its first close approach to the Sun (perihelion), coming within 77 million kilometers (48 million miles) of its surface—about half the distance between the Sun and Earth.
Over the next week mission scientists will test the spacecraft’s ten science instruments, including the six telescopes on board, which will acquire close-up images of the Sun in unison for the first time. According to ESA’s Solar Orbiter Project Scientist Daniel Müller, the images will be the closest images of the Sun ever captured.“We have never taken pictures of the Sun from a closer distance than this,” Daniel says. “There have been higher resolution close-ups, e.g. taken by the four-meter Daniel K. Inouye Solar Telescope in Hawaii earlier this year. But from Earth, with the atmosphere between the telescope and the Sun, you can only see a small part of the solar spectrum that you can see from space.”
NASA’s Parker Solar Probe, launched in 2018, makes much closer approaches (6.2 million km at ...
