		The largest of Phobos' craters, Stickney, was named after the wife of Asaph Hall, the astronomer who discovered the moons of Mars.
		Stickney crater is 10 km in diameter, which is almost half of the average diameter of Phobos!
		The linear features and crater chains from lower left to upper right are believed to be results of the impact which formed Stickney crater.

		Cratering of the surface of Phobos continued during and after the formation of the regolith, and the regolith is saturated with craters.
		Crater densities on both satellites are comparable to densities on the lunar uplands, a fact that suggests ages of up to a few billion years.
		The rim of Stickney, the largest crater on Phobos, is seen at the lower left, with a large network of grooves radiating from it.

	Stickney Crater - Phobos
		Because Phobos is only 28 by 20 kilometers (17 by 12 miles), the moon must have been nearly shattered from the force of the impact that caused the giant crater.
		Grooves that extend across the surface from Stickney appear to be surface fractures caused by the impact.
		Near the crater, the grooves measure about 700 meters (2300 feet) across and 90 meters (295 feet) deep.

	Phobos (moon)
		The most prominent feature on Phobos is the large crater named Stickney, the maiden name of Asaph Hall's wife.
		Like Mimas' crater Herschel on a smaller scale, the impact that created Stickney must have almost shattered Phobos.
		The large crater (mostly in darkness) on the upper left of the image is the crater Stickney.

	Stickney (Site not responding. Last check: 2007-11-05)
		Stickney is a crater located on Phobos, Mar's moon.
		It is believed that the force causing the crater nearly shattered the moon on impact.
		Grooves across the surface of Phobos appear to be fractures from the impact and are as large as 700 meters across and 90 meters deep!

	WTP: Mars: Grooves and Lines
		One of the most striking features on the 27 km (16 mi) diameter, irregularly shaped Phobos is the presence of grooves over most of its surface.
		The grooves seem to radiate in all directions from the giant Stickney crater and converge on the opposite side of the satellite at a region close to the Stickney antipode.
		The grooves are best developed near Stickney, where some measure 700 m (2307 ft) across and 90 m (294 ft) deep.

		This image of Phobos, the inner and larger of the two moons of Mars, was taken by the Mars Global Surveyor on August 19, 1998.
		Individual boulders are visible on the near rim of the crater, and are presumed to be ejecta blocks from the impact that formed Stickney.
		This crater is nearly half the size of Phobos and these grooves may be fractures caused by its formation.

	Geomorphology: Chapter 10 Plate P-9
		The largest crater on Phobos, Stickney (facing the viewer), is about 10 km wide; formation of a larger crater probably would have broken the satellite into pieces.
		The dense crater population of the satellites of Mars clearly implies that regolith-forming processes have been active, but one would expect most of the ejecta from impact craters to be blown completely off because of the low gravity.
		However, the subdued outlines of craters and grooves (the latter on Phobos) imply that these are not bare rock surfaces, but are blanketed with debris.

		Stickney Crater is itself is six miles wide – almost half the
		Grooves created on Phobos due to the impact radiate out from the crater and in some places, can measure to 294 feet deep.
		Because of the size of the crater, it is thought that the impact must have nearly destroyed Phobos.

		The grooves seem to radiate in all directions from the giant Stickney crater (left) and converge on the opposite side of the satellite at a region close to the Stickney antipode.

	Phobos
		Its most impressive feature is the crater Stickney, some 9 km (6 miles) in diameter, named after Angeline Stickney (1830-1892), the maiden name of Asaph Hall's wife, known for her persistent encouragement of her husband as he strove to track down the Martian satellites.
		The formation of this comparatively huge crater would have involved an impact which almost shattered the little satellite.
		High resolution images of Stickney, obtained by the Mars Global Surveyor, have shown it to be filled with fine dust and have provided evidence of boulders sliding down its steep sides.

		The largest crater, Stickney (top left), is 10 kilometers in diameter, and about half the size of Phobos.
		This crater is named after Angeline Stickney (1830-1892), wife of Asaph Hall (1829-1907), who discovered the two Martian moons.
		Individual boulders can be seen near the rim of the crater, presumably ejected by the impact that formed Stickney.

	Crater chains, Questioning the accepted theory? - Page 3 - Bad Astronomy and Universe Today Forum
		The reason that it is stated that these hit almost simultaneously is based on the known properties of explosives and high energy impacts (big fast bullets) to eject the surrounding material from the impact along the line of simultaneous impacts or explosions.
		Had these craters formed at much less than at the same time the results would have the ejecta material blanketing them to a much greater degree as is shown by other crater formations.
		A question I have is other than it being a theory, that all these craters we see out there in our solar system is just taken for granted that they were caused by impacts of natural causes like comets or meteors or what ever you want to call space chunks.

		These are said to radiate from Stickney, and are explained by scientists as cracks in the moon caused by the great impact which created the large crater.
		If they are all a result of a huge impact, the "cracks" should surround the crater as the spokes of a wheel are centered on the hub.
		They aren't radiating from Stickney Crater, but are parallel even in areas not associated with the crater at all.

		There is a large crater on the Mars end of Phobos called Stickney (after the wife of Phobos' discoverer).

		The series of straight lines that run from the upper left to the center of the moon are striations.
		These striations are thought to be fractures created by the event that formed Stickney Crater.

		When Mariner 9 found this crater to be protruding above a global dust storm, it was quickly recognized for what it is. The "Snow of Olympus" is in fact the water-ice cloud formation that often forms on the leeward side of the volcano in the late afternoon.
		It is thought the dark channels at the rim of the crater (to the left of the frame) might have resulted from seepage of fluid into the crater and the dark floor material may represent sediment transported into the crater by the seeping water.
		These spectacular dunes lie in the bottom of Proctor Crater, located at 47.9°S, 330.4°W. The dunes are up to 100 meters high and cover an area of hundreds of square kilometers.

		The wall around the crater is 5 kilometers high, and that central peak rises 6 kilometers above the surface (many impact craters have a large central peak which is caused by a pressure rebound from the impact).
		As it is, there are enormous cracks on the opposite side of Mimas from the crater where the pressure waves from the impact converged and were amplified, wreaking havoc on the surface.
		Loyal Reader Pete Maynard pointed out to me that the crater Stickney on Mars' moon Phobos is also a whopper, and is roughly the same size in proportion to Phobos as Herschel is to Mimas.

		By looking back and forth between the Spirit and Mars Express views you realize that Spirit even resolved a pretty small crater that's right on the night/day terminator.

		There are grooves that stretch around the crater Stickney.

		The impact from this crater has a significant effect on the structure of the entire moon, and lines or "grooves" are along the surface of Phobos that were formed as a result of this impact.
		Some of these radiate from Stickney, the large impact crater that distorts the shape of the moon, and are thought to indicate that the force of the impact nearly shattered the small body.
		Phobos is locked in a "death spiral" around Mars, and it'll eventually crash into the planet, or be torn apart and turned into a short-lived ring.

		This image is a close-up of the far wall of the Stickney crater, 10 kilometers (6 miles) in diameter, that is the largest crater on Phobos.
		The presence of material of different brightness on the far crater slopes and in some of the grooves shows that the satellite is heterogeneous (that is, it is made of a mixture of different types of materials).
		The motion of debris down slopes is guided by gravity, which is only about 1/1000th that of the Earth -- e.g., a 68-kilogram (150-pound) person would weigh only about 57 grams (2 ounces) on Phobos.
