What is the name of the first meteorite discovered on Mars?

The first meteorite discovered on Mars was Heat Shield Rock.

NASA’s Opportunity rover found Heat Shield Rock on the plains of Meridiani Planum in January 2005. The basketball-sized object was spotted near the remains of Opportunity’s own discarded heat shield, which inspired its informal name. Scientists quickly suspected it was not a normal Martian rock because its surface and spectral properties suggested a metallic composition.

Measurements by Opportunity’s instruments confirmed that it was an iron-nickel meteorite, composed of about 93% iron and 7% nickel, with small traces of germanium and gallium. Its pitted surface, known as regmaglypts, also resembled meteorites found on Earth that had been shaped by atmospheric entry.

The rock’s formal Meteoritical Society name is the Meridiani Planum meteorite, because meteorites are officially named for their discovery location. “Heat Shield Rock” remains the familiar mission name and is the answer normally expected in trivia. It should not be confused with Bounce Rock, a Martian basaltic rock examined by Opportunity that may resemble meteorites from Mars found on Earth.
