Snæbjörn Galti Wikipedia
Snøbjørn Galte Holmsteinsson (Old Norse: Snæbjörn Galti, c. 910– c. 978) was the first Norseman to intentionally navigate to Greenland, doing so in 978 CE.
His voyage followed the accidental discovery of lands west of Iceland by Gunnbjörn Ulfsson, probably in the early 10th century. According to records from the time, Galte led the first attempt to colonize the eastern coast of Greenland. However his effort ended with disaster and he was killed in internal strife. There had been a saga about the voyage of Snøbjørn Galte (Snæbjörn saga galti), but it has been lost over time.
Erik the Red (Eiríkr Rauði) would become the first permanent European settler. In 982 Eric the Red arrived from Iceland. According to the Saga of Erik the Red (Eiríks saga rauða), he spent his three years exploring the west coast of Greenland. Apparently he planned his journey much better and probably was luckier with the weather as well as maintaining better control of his crew.
