A new map of the magnetosphere of Mercury
Using data obtained during the June 2023 fly-by by the European-Japanese probe BepiColombo, scientists have now published a new detailed map of the magnetic field that surrounds Mercury.
That map is to the right. From the caption:
A textured sphere representing Mercury is shown with magnetic field lines compressed on the sunward side and streaming out into a tail on the nightside. The BepiColombo spacecraft’s trajectory is drawn passing through the magnetosphere from dawn to dusk, close to the planet’s surface. Various features in the magnetosphere are depicted and labelled with text. Following the order in which they were detected by the spacecraft, this includes the bow shock, magnetopause, low-latitude boundary layer, cold ion cloud, plasma sheet horn and ring current.
You can read the peer-reviewed paper here [pdf]. Note that this research does not include data obtained during BepiColumbo’s fourth fly-by of Mercury in September. Furthermore, the spacecraft will do two more fly-bys before arriving in orbit in 2026, where it will then separate into two separate orbiters in complementary orbits. Thus, this magnetic map of Mercury is merely a rough draft, and will be significantly refined by the end of the mission.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
