NASA to voyage to 'golden asteroid' worth $10,000 quadrillion this fall [chron.com]:
Riches beyond our wildest dreams are apparently within reach--at least, within the reach of NASA--in the form of an asteroid made of gold and other metals valued in the neighborhood of ten thousand quadrillion dollars.
[Psyche,] the ultra-valuable asteroid—which appears to be made largely of iron, nickel, gold [iop.org] and other rare metals—orbits the Sun [chron.com] between Mars and Jupiter [chron.com]. It measures 140 miles wide and is shaped somewhat like a potato [nasa.gov], according to astronomers.
It's been said [globalnews.ca] that Psyche could be worth $10,000 quadrillion—more than the entire economy on our planet.
[...]The Psyche mission would be NASA's first-ever [chron.com] visit to a world rich in metal, rather than rock or ice. The spacecraft is expected to reach [the] asteroid in August 2029[.]
