Earth Independence

Dr. Doug Plata from The Space Development Network hosted a two part session on Earth independence. This involves the idea of reducing a future space colony's dependence on importing essential goods from Earth for survival. Independence from Earth can only be achieved via in-situ resource utilization, which is the process of converting local resources into required goods. Until this happens, any future space colony will be dependent on shipments from Earth for survival.

“Don’t drink the water!” - Toxic Elements Found in Meteorites

A science team led by Alessondra Springmann found that heating up various types of carbonaceous chondrite meteorites released water as well as other volatile and toxic trace elements. Water is likely one of the very first resources that will be sourced from space for use in space. It is versatile for a variety of applications, including rocket propellant, consumption by astronauts, and bulk radiation shielding.

Lunar Polar Ice Everywhere, but Only on Surface

An international team of Chinese, American, and Russian scientists may have conducted the most extensive study of lunar Permanently Shadowed Region (PSR) ice yet performed. By comparing the reflections from flat surfaces in major PSRs to those of adjacent non-PSRs, they determined that the vast majority contain ice. However, the ice appears to be restricted to the uppermost surface.

Why the Lunar South Pole?

NASA was recently directed to return to the Moon by 2024, an announcement first made in remarks given by Vice President Mike Pence at the 5th meeting of the National Space Council on March 26th. However this huge announcement and acceleration in schedule also came with another set of exciting details. He stated, the “lunar South Pole holds great scientific, economic, and strategic value” and that “when the first American astronauts return to the lunar surface, that they will take their first steps on the Moon’s South Pole.” But why the focus on the Moon’s south pole? He explored that as well, saying that we will “mine oxygen from lunar rocks” and “use nuclear power to extract water from the permanently shadowed craters of the South Pole”. These statements are exciting because they specifically include the use of in-situ resource utilization on the Moon, and select human landing locations near the South Pole due to proximity to those resources.
