Question: A Mars crater is named after the successor of who?

full_context: Document 1: Handel (crater): Handel is a crater on Mercury. It has a diameter of 166 kilometers. Its name was adopted by the International Astronomical Union in 1976. Handel is named for the British-German composer George Frideric Handel, who lived from 1685 to 1759.
Document 2: Halley (Martian crater): Halley Crater is an impact crater in the Argyre quadrangle of Mars, located at 48.7°S latitude and 59.3°W longitude. It is 84.5 km in diameter and was named after Edmond Halley, and the name was approved in 1973.
Document 3: Great comet: A great comet is a comet that becomes exceptionally bright. There is no official definition; often the term is attached to comets such as Halley's Comet, which are bright enough to be noticed by casual observers who are not looking for them, and become well known outside the astronomical community. Great comets are rare; on average, only one will appear in a decade. Although comets are officially named after their discoverers, great comets are sometimes also referred to by the year in which they appeared great, using the formulation "The Great Comet of ...", followed by the year.
Document 4: William Herschel: Frederick William Herschel, (German: "Friedrich Wilhelm Herschel" ; 15 November 1738 – 25 August 1822) was a British astronomer and composer of German and Czech-Jewish origin, and brother of fellow astronomer Caroline Herschel, with whom he worked. Born in the Electorate of Hanover, Herschel followed his father into the Military Band of Hanover, before migrating to Great Britain in 1757 at the age of nineteen.
Document 5: Edmond Halley: Edmond (or Edmund) Halley, FRS (pronounced ; 8 November [O.S. 29 October] 1656 – 25 January 1742 [O.S. 14 January 1741] ) was an English astronomer, geophysicist, mathematician, meteorologist, and physicist who is best known for computing the orbit of Halley's Comet. He was the second Astronomer Royal in Britain, succeeding John Flamsteed.
Document 6: Victoria (crater): Victoria is an impact crater on Mars located at 2.05°S, 5.50°W in the Meridiani Planum extraterrestrial plain, lying situated within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars. This crater was first visited by the Mars Exploration Rover "Opportunity". It is roughly 730 metres wide, nearly eight times the size of the crater Endurance, visited by "Opportunity" from sols 951 to 1630. It is informally named after "Victoria" – one of the five ships of Ferdinand Magellan and the first ship to circumnavigate the globe – and formally named after Victoria, Seychelles. Along the edges of the crater are many outcrops within recessed alcoves and promontories, named for bays and capes that Magellan discovered.
Document 7: Christiaan Huygens: Christiaan Huygens, FRS ( or ; ] ) (Latin: "Hugenius" ) (14 April 1629 – 8 July 1695) was a prominent Dutch mathematician and scientist. He is known particularly as an astronomer, physicist, probabilist and horologist.
Document 8: Reuyl (crater): Reuyl is a crater in the Aeolis quadrangle of Mars, located at 9.8° south latitude and 193.2° west longitude. It measures 85.9 kilometers in diameter and was named after Dirk Reuyl, a Dutch-American physicist and astronomer (1906–1972) who made astronomical measurements of the diameter of Mars in the 1940s.
Document 9: Kepler (Martian crater): Kepler is a crater on Mars, located in the Eridania quadrangle at 46.8° S, 140.9° E. It measures approximately 228 km and was named in 1973, by the International Astronomical Union, in honor of the astronomer Johannes Kepler. A section of the floor of Kepler was photographed by the HiRISE camera aboard the Mars Reconnaissance Orbiter on 25 March 2006.
Document 10: Edwin Hubble: Edwin Powell Hubble (November 20, 1889 – September 28, 1953) was an American astronomer. He played a crucial role in establishing the fields of extragalactic astronomy and observational cosmology and is regarded as one of the most important astronomers of all time.
Document 11: Robert Hooke: Robert Hooke FRS ( ; 28 July [O.S. 18 July] 1635  – 3 March 1703) was an English natural philosopher, architect and polymath.
Document 12: Jeremiah Horrocks: Jeremiah Horrocks (1618 – 3 January 1641), sometimes given as Jeremiah Horrox (the Latinised version that he used on the Emmanuel College register and in his Latin manuscripts), was an English astronomer. He was the first person to demonstrate that the Moon moved around the Earth in an elliptical orbit; and he was the only person to predict the transit of Venus of 1639, an event which he and his friend William Crabtree were the only two people to observe and record.
Document 13: Eberswalde (crater): Eberswalde, formerly known as Holden NE, is a partially buried impact crater in Margaritifer Terra, Mars. Eberswalde Crater lies just to the north of Holden Crater, a large crater that may have been a lake. The 65.3-km-diameter crater, centered at 24°S, 33°W, is named after the German town of the same name, in accordance with the International Astronomical Union's rules for planetary nomenclature. It was one of the final four proposed landing sites for the Mars rover Mars Science Laboratory mission. This extraterrestrial geological feature lies situated within the Margaritifer Sinus quadrangle (MC-19) region of Mars. Although not chosen, it was considered a potential landing site for the "Mars 2020" rover, and in the second Mars 2020 Landing Site Workshop it survived the cut and was among the top eight sites still in the running.
Document 14: Nhill (crater): Nhill is a Martian impact crater, 22 kilometers in diameter. It is located at 29°S, 103.4°W, southwest of the crater Llanesco and northwest of the crater Dinorwic. It is named after the town of Nhill in Victoria, Australia, and its name was adopted by the International Astronomical Union in 1991. According to a surface age map of Mars based on US Geological Survey data, the area around Nhill is from the Noachian epoch, which places the area's age at 3.8 to 3.5 billion years ago. The crater is relatively shallow, and is only about 300 meters deep.
Document 15: List of Halley-type comets: The following is a list of Halley-type comets (HTCs), which are periodic comet with an orbital period between 20 and 200 years, often appearing only once or twice within one's lifetime. The majority come from between the orbits of Saturn and Neptune; Due to the nature of their orbits, their orbits can be perturbed by the giant planets and sent into orbits too far from the Sun to outgas, and vice versa. Minor planets in comet-like orbits similar to HTCs that never come close enough to the Sun to outgas are called Centaurs. HTCs are named after the first discovered member, and the first discovered periodic comet, Halley's Comet, which orbits the Sun in about 75 years, and passing as far as the orbit of Neptune.
