Bopoulu

Planet	Mars
Region	Meridiani Planum
Diameter	19 kilometres (12 mi)^[1]^[2]

Bopolu is an impact crater located within the Meridiani Planum extraterrestrial plain of Mars.^[2] Bopulu was seen by Opportunity rover in 2010 in the distance, and with some of its rim visible.^[2] Bopoplu was officially named in 2006 along with 31 Mars craters.^[3] Research has indicated that the impact that is thought to have created Bopulu went so deep that it went through existing layers and ejected older material from Mars' Noachian period.^[1] Bopulu is a 19 kilometres (12 mi) diameter wide crater south of the Opportunity MER-B landing site, a rover which operated in the region starting in 2004 and therefore resulted in greater exploration and study of craters in this region.^[1] Bopulu was identified as a possible source for the Bounce Rock ejecta fragment^[1] Bounce rock, which was examined by the MER-B rover, was found to be similar in composition to the shergottite class of Mars meteorite found on Earth (Meteorites found on Earth determined to be from Mars).^[1]

Bopulu is said be younger than the Burns Formation that predominates in the area.^[4] Bopolu has been studied, along with Tooting crater, to try and better understand the geology of Endeavour crater which MER-B rover reached and could explore in situ.^[5]

Bopolu is named for a town in nation of Liberia (see Bopolu, Africa); the name was approved by the IAU in September 2006.^[6] Bopolu crater has a feature ID of 14185.^[6]

Color-coded for minerals and annotated, Bopolu crater is centered in this image with its distinctive ejecta detected by MRO's CRISM instrument. Nearby is Endeavour crater, reached by MER-B in 2011
The rim of Bopolu crater is visible on the horizon of this March 2010 image taken by the Mars rover Opportunity; Bopolu is 65 kilometers (40 miles) away, when the rover was making its traverse to the closer Endeavour crater.^[2]
