Joseph Ashbrook (April 4, 1918 – August 4, 1980) was an American astronomer.
He went through old archives of observations from centuries past to determine a highly precise value for the rotation period of Mars —to within a few thousandths of a second.
Ashbrookcrater on the Moon and the asteroid 2157 Ashbrook are named after him.
According to Ashbrook [14], the average slope of the dome flank is equal to the solar altitude when x = 0.25, assuming a hemispherical shape of the dome.
The effective height of the dome was obtained by determining elevation differences between the summit of the dome and its surrounding, leading to a height of (105 ± 15) m.
The crater pit may be deeper than it appears in the 3D profile of Fig.
Ajo - Crater Range - In the 1950's a couple was married in Ajo and was driving to Lake Tahoe for their honeymoon.
When they entered into crater range, which was lined with hills and huge rocks on both sides, around midnight their car crashed into a rock and they were both killed.
It is said that if you drive through crater range after midnight you can see their car and the couple off to the side of the road trying to flag down help.
A study about two lunar cones located near the crater Milichius [1] will be published in a next issue ofSelenology, the Journal of the American Lunar Society (ALS).
The solar altitude (Alt) as seen from Milichius π (located at 31.20° W and 10.08° N) and the colongitude (C) were calculated using the Lunar Observer's Tool Kit software by Harry Jamieson.
According to Ashbrook [7], the average slope of the dome flank is equal to the solar altitude when x = 0.25, where x is the fraction of the dome diameter that is covered by fl shadow.

Mr Ashbrook carried no note, and none was found during a search of his home, which was near the church.
Linda McConn, who has lived in Mr Ashbrook’s neighbourhood since 1961 and was a high school classmate of his sister, viewed him as a harmless eccentric.
Mr Ashbrook carried a 9 mm semiautomatic handgun and a.380 calibre handgun, pausing during the attack to reload, using three clips in all, he added.
When I arrived at the scene, some of the fires spawned by the blast were still burning.
Melted and twisted hulks of what used to be cars dotted the street, which revealed its primary wound: an eight-foot-wide crater implanted where the 500-pound vehicle borne improvised explosive device had detonated.
While the hotel sustained substantial damage, attention was now focused on the shattered remains of a two-story home across the street.
But by 1961 the IAU decided the feature was neither a crater nor a mountain and so the name was officially deleted.
Hyginus W is obviously a crater (or more than one) that has mostly escaped total burial, but only the sides of its rim that are radial to Imbrium have survived.
Other linear remains of crater walls occur between the fresh craters Hyginus E, F and C. And look to the east at Boscovich, Julius Caesar and many similar craters instantaneously aged by Imbrium.
Included with the cookies and much needed coffee was a box filled with toys that her daughter Cassandra, who must be six by now, had helped her mother send for the Iraqi children.
Thankfully, no one was injured, and despite the size of the explosion (I drove past the sizable crater), the vehicle looked relatively unscathed.
As I was leaving for the day, I received news that they were able to catch the terrorist who set the bomb red-handed.
The group is highly respected in China, having won both national and international prizes for their performances.
Most of the delegates are performers, including musicians, acrobats and members of the Shaolin Temple Wushu Monk Troupe, which performs a sacred form of martial arts.
Meanwhile, Carlson had opened a bottle of Crater Lake vodka to share with his old friends.
