Mercury Transit 2019: How the Space Fleet Will Observe Rare Space Events



On Monday (November 11th), Mercury will move through the face of the sun and several spacecraft will be targeted on a rare occasion.

The spacecraft has captured incredible images of Mercury's past transits, and this year promises exciting observations from space. NASA's Solar Dynamics Observatory (SDO) and The Solar and Heliosphere Observatory (SOHO) will monitor the sun during approximately 5.5 hours of Mercury, and Japan may Japan also provide a close

Earth-based scouters in North America, South America, Europe, Africa and even Antarctica can view the event using the secure ISO-certified security solar monitoring system ̵

1; weather permitting. Those in Alaska, the Pacific, and Asia will not capture the event, because the sun will be below the horizon when Mercury crosses the star as a traveling flaw. Fortunately, the teams behind several space missions will share unobstructed views on Mercury's transit.

Now in its ninth year in orbit on our planet, the SDO continues to measure the Sun's interior, magnetic field, and the terribly hot outer atmosphere of a star called the Crown . Three scientific experiments aboard the SDO track these lucky ones around the sun: Atmospheric Imaging System (AIA), EUV Variability Experiment (EVE) and Heliosseismic and Magnetic Imaging (HMI). Throughout its lifetime, the nearly 24-hour Sun coverage has generated over 350 million images and has been used in over 3000 research documents, according to NASA .

The SDO team will regularly update its website with the latest Mercury transit views from November 11, available here starting around 7am EST (1200 GMT), about half an hour before the first contact on Mercury (when the silhouette of the planet touches the solar disk for the first time).

NASA also manages SOHO, a 12-space spacecraft built in collaboration with the European Space Agency. SOHO has been in space longer than SDO, launching more than two decades ago. It maintains regular sections of the sun and creates several sun time views in gif movie format. Like the SDOs, they are regularly updated on the NASA website. Mercury is likely to appear in these views, though perhaps as a speeding place in a fast-moving video. SOHO videos can be watched here .

Hinode A satellite observing solar energy hosted by the Japan Aerospace Exploration Agency (JAXA) has produced great images of Mercury transits in the past. The mission team will post images sometime after the Nov. 11 event, a NASA spokesman told Space.com. (Hinode is also part of the Solar Ground Probe Program at NASA's Heliophysics Division at NASA's Science Mission Directorate in Washington.) The 13-year mission is equipped with three powerful telescopes to help scientists learn how solar is affected phenomena such as heating and magnetism. the star's dramatic activity, such as sun flames .

Hinode has also caught larger shadows passing by the sun, such as the Great American Solar Eclipse of 2017 .

There are several newer missions that follow the sun and Mercury. The joint European-Japanese BepiColombo mission launched last year and has already taken over 500 images ( like this selfie ) in its long journey to reach Mercury. But it is not designed to look at the sun, Erica Verbelen, a spokesman for ESA, told Space.com that it will not see solar transit on Monday.

NASA's Parker Park Probe has the star's name right at the head of its mission, but its instruments are currently off. Even if they were included, which would happen when the probe is closer to the sun in its orbit outlined by the mission, the Parker solar probe is not designed to take direct sun shots, said NASA's Karen S. Fox spokesman Space.com. Rather, observations of on the solar wind flowing from the sun are needed.
