Ernst Krenkel Observatory (Russian: Обсерватория имени Эрнста Кренкеля), also known as Kheysa, was a former Soviet rocket launching site located on Heiss Island, Franz Josef Land. It is named after a famous Arctic explorer Ernst Krenkel, a member of the crew of the North Pole-1 drift ice station and other notable Soviet polar expeditions.
