Researchers say space atomic clocks could help uncover the nature of dark matter //www.koonmotors.com/releases/2022/12/221205121538.htm Studying an atomic clock on-board a spacecraft inside the orbit of Mercury and very near to the Sun could be the trick to uncovering the nature of dark matter. Mon, 05 Dec 2022 12:15:38 EST //www.koonmotors.com/releases/2022/12/221205121538.htm Mercury has magnetic storms //www.koonmotors.com/releases/2022/03/220331101604.htm An international team of scientists has proved that Mercury, our solar system's smallest planet, has geomagnetic storms similar to those on Earth. Their finding, a first, answers the question of whether other planets, including those outside our solar system, can have geomagnetic storms regardless of the size of their magnetosphere or whether they have an Earth-like ionosphere. Thu, 31 Mar 2022 10:16:04 EDT //www.koonmotors.com/releases/2022/03/220331101604.htm Why does Mercury have such a big iron core? //www.koonmotors.com/releases/2021/07/210702154314.htm A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle. For decades, scientists argued that hit-and-run collisions blew away much of Mercury's rocky mantle and left the big, dense, metal core inside. But new research reveals that collisions are not to blame -- instead, the density, mass and iron content of a rocky planet's core is influenced by its distance from the sun's magnetic field. Fri, 02 Jul 2021 15:43:14 EDT //www.koonmotors.com/releases/2021/07/210702154314.htm Cosmic diamonds formed during gigantic planetary collisions //www.koonmotors.com/releases/2020/09/200929123418.htm Geoscientists have found the largest extraterrestrial diamonds ever discovered - a few tenths of a millimeter in size nevertheless - inside meteorites. Together with an international team of researchers, they have now been able to prove that these diamonds formed in the early period of our solar system when minor planets collided together or with large asteroids. These new data disprove the theory that they originated deep inside planets - similar to diamonds formed on Earth - at least the size of Mercury. Tue, 29 Sep 2020 12:34:18 EDT //www.koonmotors.com/releases/2020/09/200929123418.htm Mercury's scorching daytime heat may help it make its own ice at caps //www.koonmotors.com/releases/2020/03/200313155329.htm Despite Mercury's 400-degree Celsius daytime heat, there is ice at its caps. And now a study shows how that Vulcan scorch probably helps the planet closest to the sun make some of that ice. Fri, 13 Mar 2020 15:53:29 EDT //www.koonmotors.com/releases/2020/03/200313155329.htm Mercury has a solid inner core: New evidence //www.koonmotors.com/releases/2019/04/190417130007.htm Scientists have long known that Earth and Mercury have metallic cores. Like Earth, Mercury's outer core is composed of liquid metal, but there have only been hints that Mercury's innermost core is solid. Now, in a new study, scientists report evidence that Mercury's inner core is indeed solid and that it is very nearly the same size as Earth's solid inner core. Wed, 17 Apr 2019 13:00:07 EDT //www.koonmotors.com/releases/2019/04/190417130007.htm The true power of the solar wind //www.koonmotors.com/releases/2018/06/180612105753.htm The planets and moons of our solar system are continuously being bombarded by particles from the sun. On the Moon or on Mercury, the uppermost layer of rock is gradually eroded by the impact of sun particles. New results show that previous models of this process are incomplete. The effects of solar wind bombardment are much more drastic than previously thought.

Tue, 27 Mar 2018 13:20:14 EDT //www.koonmotors.com/releases/2018/03/180327132014.htm Middle-aged sun observed by tracking motion of Mercury //www.koonmotors.com/releases/2018/01/180118141822.htm Like the waistband of a couch potato in midlife, the orbits of planets in our solar system are expanding. It happens because the Sun's gravitational grip gradually weakens as our star ages and loses mass. Now, scientists have indirectly measured this mass loss and other solar parameters by looking at changes in Mercury's orbit. Thu, 18 Jan 2018 14:18:22 EST //www.koonmotors.com/releases/2018/01/180118141822.htm NASA investigates invisible magnetic bubbles in outer solar system //www.koonmotors.com/releases/2017/11/171101151201.htm Forty years ago, the twin Voyagers spacecraft were launched to explore the frontiers of our solar system, and have since made countless discoveries, including finding magnetic bubbles around two of the outer planets. Wed, 01 Nov 2017 15:12:01 EDT //www.koonmotors.com/releases/2017/11/171101151201.htm Small collisions make big impact on Mercury's thin atmosphere //www.koonmotors.com/releases/2017/09/170929112952.htm Mercury, our smallest planetary neighbor, has very little to call an atmosphere, but it does have a strange weather pattern: morning micro-meteor showers.

The researchers discovered the valley using a new high-resolution topographic map of part of Mercury's southern hemisphere created by stereo images from NASA's MESSENGER spacecraft. Wed, 16 Nov 2016 10:40:13 EST //www.koonmotors.com/releases/2016/11/161116104013.htm Tatooine worlds orbiting two suns often survive violent escapades of aging stars //www.koonmotors.com/releases/2016/10/161012121208.htm Planets that revolve around two suns may surprisingly survive the violent late stages of the stars' lives, according to new research. The finding is surprising because planets orbiting close to a single sun, like Mercury and Venus in our solar system, would be destroyed when the aging star swells into a red giant. Wed, 12 Oct 2016 12:12:08 EDT //www.koonmotors.com/releases/2016/10/161012121208.htm Earth's carbon points to planetary smashup //www.koonmotors.com/releases/2016/09/160905114511.htm Research suggests that virtually all of Earth's life-giving carbon could have come from a collision about 4.4 billion years ago between Earth and an embryonic planet similar to Mercury. Mon, 05 Sep 2016 11:45:11 EDT //www.koonmotors.com/releases/2016/09/160905114511.htm Most volcanic activity on Mercury stopped about 3.5 billion years ago //www.koonmotors.com/releases/2016/08/160805155132.htm New research finds that major volcanic activity on the planet Mercury most likely ended about 3.5 billion years ago. These findings add insight into the geological evolution of Mercury in particular, and what happens when rocky planets cool and contract in general.

Throughout the US, sky watchers can watch Mercury pass between Earth and the sun in a rare astronomical event known as a planetary transit. Three NASA satellites will be providing images of the transit and one of them will have a near-live feed. Wed, 04 May 2016 09:29:38 EDT //www.koonmotors.com/releases/2016/05/160504092938.htm Rare transit of Mercury to take place on 9 May //www.koonmotors.com/releases/2016/04/160427151210.htm On 9 May there will be a rare transit of Mercury, when the smallest planet in our Solar System will pass directly between the Earth and the Sun. The last time this happened was in 2006, and the next two occasions will be in 2019 and 2032. During the transit, which takes place in the afternoon and early evening in the UK, Mercury will appear as a dark silhouetted disk against the bright surface of the Sun. Wed, 27 Apr 2016 15:12:10 EDT //www.koonmotors.com/releases/2016/04/160427151210.htm Mercury's mysterious 'darkness' explained //www.koonmotors.com/releases/2016/03/160307112950.htm Scientists have long been puzzled by Mercury's very dark surface. Previously, scientists proposed that the darkness came from carbon accumulated by comet impacts. Now scientists confirm that carbon is present at Mercury's surface, but that it most likely originated deep below the surface, in the form of a now-disrupted and buried ancient graphite-rich crust, which was later brought to the surface via impacts after most of the current crust formed.

The mission will end sometime this spring, when the spacecraft runs out of propellant and the force of solar gravity causes it to impact the surface of Mercury. But the team initiated a "hover" observation campaign designed to gather scientific data from the planet at ultra-low altitudes until the last possible moment. Engineers have devised a series of orbit-correction maneuvers (OCMs) over the next five weeks -- the first of which was carried out today -- designed to delay the inevitable impact a bit longer.

The planets are located in a system called Kepler-37, about 210 light-years from Earth in the constellation Lyra. The smallest planet, Kepler-37b, is slightly larger than our moon, measuring about one-third the size of Earth. It is smaller than Mercury, which made its detection a challenge.

The flyby, 36 million miles (58 million kilometers) away from Earth, gave America its first bona fide space "first" after five years in which the Soviet Union led with several space exploration milestones. Designed and built by NASA's Jet Propulsion Laboratory in Pasadena, Calif., the successful Mariner 2 spacecraft ushered in a new era of solar system exploration.
