This is the first time hydrogen isotopes have been measured in eucrite meteorites.
In particular, howardite and eucrite meteorites, which are common species found on Earth, have been used to study asteroid Vesta, their parent body.
The new findings solidly confirm the connection between Vesta and a class of meteorites found on Earth called the Howardite, Eucrite and Diogenite meteorites, which have the same ratios for these elements.
Although Vesta and its family are located between Mars and Jupiter, smaller pieces of these asteroids can be found in meteorite collections on Earth, including most eucrite, howardite and diogenite meteorites.
This one, too, resembles a eucrite, but its ratio of iron to manganese resembles that of other lunar rock types, notes Keizo Yanai of the Institute of Polar Research in Tokyo.
This basin appears to have excavated into the mantle of Vesta, exposing material spectrally similar to diogenite meteorites; Vesta's crust is spectrally similar to eucrite and howardite meteorites, thus confirming that Vesta and its family of asteroids are the source of the howardite-eucrite-diogenite (HED) family of basaltic achondrite meteorites.
The rock belongs to a group of meteorites known as eucrites and considered to be fragments chipped from the giant asteroid 4 Vesta.
The three meteorite types -- the eucrites, howardites and diogenites -- came from an asteroid big enough for its surface rock to melt, possibly from the heat of radioactive elements inside it, concludes a team headed by Dale P.
A kind of meteorite called eucrites, for example, has been tentatively associated with the large asteroid Vesta, though this link is typical of such studies in that the limited data available fall far short of proving the eucrites actually came from Vesta.
