Benchmarks: September 26, 1991: Crew sealed inside Biosphere 2

It takes about an hour to drive from Tucson, Ariz., to the Biosphere 2 research facility, perched atop a plateau in the Santa Catalina Mountains. Through its glittering glass walls, you can still see the shadowy silhouette of the Brazilian rainforest that grows inside. Indeed, the facility once enclosed numerous small-scale experimental ecosystems — from a swath of swaying savanna to a 700,000-gallon ocean complete with its own coral reef. And, beginning on Sept. 26, 1991, Biosphere 2 enclosed a crew of four men and four women who would call the bubble home for two years.

The Syracuse University lava experiments

Pouring Lava

Melting a batch of the ancient basalt takes about four hours, but we hold the lava above its melting point for much longer to ensure that it is completely melted and to remove unwanted volatiles such as water. The lava is then poured at temperatures of 1,100 to 1,350 degrees Celsius, comparable to eruption temperatures of natural lava. We monitor it with a spot calorimeter and a Forward-Looking Infrared (FLIR) camera, the same instrument conventionally used at lava flows in the field.
