That is good news for commercial ventures where cost, power, and launch weight are all at a premium. The key to the new instrument is a recently discovered material, europium-doped strontium iodide SrI 2. This is a transparent crystal that can act as an extremely efficient gamma-ray detector.
It registers the passage of gamma rays by giving off flashes of light that can be detected and recorded. It also needs vacuum-tube technology so it consumes too much energy to run on batteries. Science Health Culture Environment.

In the next section, you will find out how asteroid mining operations might supply the Earth and its colonies on other planets with a plenitude of materials. How Asteroid Mining Will Work.
The main-belt asteroid Ida is a metal-rich S-type that could be mined for space colony supplies. C-type - More than 75 percent of known asteroids fit into this category. The composition of C-type asteroids is similar to that of the sun without the hydrogen, helium and other volatiles.
S-type - About 17 percent of asteroids are this type. These contain deposits of nickel, iron and magnesium. Prospector-1, the first commercial interplanetary mining mission by Deep Space Industries, will intercept a near-Earth asteroid to determine its value as a source of space resources.
Both Moon Express of Florida and ispace of Japan hope to win the prize by being the first privately funded team to place a rover on the moon, travel m across its surface and transmit high-definition video and images back to Earth. Get alerts on Space industry when a new story is published. The costs run high and the returns are not immediate but extraterrestrial mining is now within the realms of the probable. Beyond gaining access to precious commodities, many in the space industry see such ventures as leading to further exploration of outer space.
Two companies, California-based Deep Space Industries and Washington State—based Planetary Resources, are actively working toward extracting resources from asteroids. In order to obtain the data necessary for these determinations, observations will be continued during the present period of good visibility that lasts until September-October One of these asteroids, according to Lewis, would contain 30 million tons of nickel, 1. Deep Space Industries DSI , a leading space technology company, announced today the closing of the first tranche of its Series A funding round. In the case of Dionysus , however, it is possible to predict eclipse events and to confirm them by subsequent measurements. Based on the four well observed events, it was then possible to determine a period of 1. The gravitational pulls of the planets later helped whittle down this primordial belt, depleting asteroids of certain sizes more than others.
