NASA is planning a mission for October 10, 2023 for the Psyche orbiter to launch and get to the asteroid by August 2029 to study. [8] 511 Davida could have $27 quadrillion worth of minerals and resources. [9] NASA estimates that between 1.1 and 1.9 million asteroids in the asteroid belt are larger than 1 kilometer in diameter. Millions are smaller.
Space probe broke orbit on 5 September 2012 and headed to Ceres; first "big four" asteroid visited by a spacecraft, largest asteroid visited by a spacecraft at the time. 4179 Toutatis: 2.45: 1934 Chang'e 2: 2012 3.2 0.70 Flyby; [1] closest asteroid flyby, first asteroid visited by a Chinese probe. 1 Ceres: 939.4 1801 Dawn: 2015–2018: 35 0.07
Asteroid mining is the hypothetical extraction of materials from asteroids and other minor planets, including near-Earth objects. [1] Notable asteroid mining challenges include the high cost of spaceflight, unreliable identification of asteroids which are suitable for mining, and the challenges of extracting usable material in a space environment.
With minerals in short supply on Earth, private companies such as California-based AstroForge and international space agencies are turning to the prospect of asteroids in space.
ISRU reverse water gas shift testbed (NASA KSC) ISRU Pilot Excavator – A NASA project. In space exploration, in situ resource utilization (ISRU) is the practice of collection, processing, storing and use of materials found or manufactured on other astronomical objects (the Moon, Mars, asteroids, etc.) that replace materials that would otherwise be brought from Earth.
The asteroid belt is theorized to become a source of valuable ores that may develop into industrial asteroid mining infrastructure, whereas Earth may export hi-tech production. [2] The factor of energy-efficiency of interplanetary transportation may become very important to estimate economic value of a trade route.
Jonathan Clark, NASA flight surgeon on six Space Shuttle missions—and whose wife, Laurel Clark, died in the Space Shuttle Columbia disaster on shuttle mission STS-107—is a consultant on space suit and crew biological environment design for Excalibur Almaz.
CAESAR (Comet Astrobiology Exploration Sample Return) is a sample-return mission concept to comet 67P/Churyumov–Gerasimenko.The mission was proposed in 2017 to NASA's New Frontiers program mission 4, and on 20 December 2017 it was one of two finalists selected for further concept development.
