Observations and Quantitative Compositional Analysis of Ceres, Pallas, and Hygiea Using JWST/NIRSpec: https://iopscience.iop.org/article/10.3847/PSJ/ad944c -> "We present JWST Near Infrared Spectrograph (NIRSpec) measurements of the three largest low-albedo main-belt #asteroids: (1) Ceres, (2) Pallas, and (10) Hygiea. Their reflectance spectra all have very similar absorptions centered near 2.72 μm attributed to Mg–OH in minerals."

#AstroForge is tracking several candidate asteroids, each of which is about 400 meters 📏 across. There is no shortage of potential targets. Scientists estimate that there are about 10 million near-Earth #asteroids ☄️, perhaps 3 to 5 percent of these are rich in #metals, so there are potentially hundreds of thousands of candidates for #mining. https://arstechnica.com/space/2024/08/against-all-odds-an-asteroid-mining-company-appears-to-be-making-headway/

📆 2016 thesis : It was found that a future space mission to harvest #asteroids ☄️ seems prosperous and even plausible in the near future if using a cost-effective mission architecture, perhaps even within a decade. The necessary knowledge increases quickly due to interests of profit and exploration and #space is among the fastest growing 📈 businesses today https://www.lunduniversity.lu.se/lup/publication/8882371

Launch costs have fallen 95% 📉 (with another massive reduction expected in the coming years) thanks to reuse, improved engineering, and increased volumes.
“In economics, we assume that resources are limited; land is limited; natural resources are limited. With #space 🌌, it allows us to change that.” https://www.theguardian.com/science/article/2024/may/03/were-in-a-new-era-the-21st-century-space-race-takes-off

#NASA has contracts with four companies to gather a small amount of material from the lunar 🌙 surface—as a proof of concept to show that extraction is possible.
NASA doesn’t have a similar demonstration for mining ⚒️ #asteroids. But the space rock seekers nevertheless continue their quest for treasure. They believe Earth needs, and will pay handily for, what space 🌌 has to offer. https://arstechnica.com/science/2024/05/in-the-race-for-space-metals-companies-hope-to-cash-in/
