Stardew Valley is a farming simulation game primarily inspired by Story of Seasons, a series by Marvelous and previously known as Harvest Moon. [1] At the start of the game, players create a character, who inherits a plot of land and a small house once owned by their grandfather in a small village called Pelican Town, located in the titular ...
Iridium Communications Inc. (formerly Iridium Satellite LLC) is a publicly traded American company headquartered in McLean, Virginia, United States.Iridium operates the Iridium satellite constellation, a system of 80 satellites: 66 are active satellites and the remaining fourteen function as in-orbit spares.

The Iridium system was designed to be accessed by small handheld phones, the size of a cell phone. While "the weight of a typical cell phone in the early 1990s was 10.5 ounces" [6] (300 grams) Advertising Age wrote in mid 1999 that "when its phone debuted, weighing 1 pound (453 grams) and costing $3,000, it was viewed as both unwieldly and expensive."
Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare".It is caused by the reflection toward the Earth below of sunlight incident on satellite surfaces such as solar panels and antennas (e.g., synthetic aperture radar).
Iridium 7 was a U.S. Iridium communications satellite. It was launched into low Earth orbit from Vandenberg Air Force Base at 14:55 GMT on 5 May 1997, by a Delta II 7920-10C carrier rocket. [ 1 ] It was operated in Plane 4 of the Iridium satellite constellation , with an ascending node of 262.4°.
One example is IrH 5 (P i Pr 3) 2 (i Pr = isopropyl). [34] The ternary hydride Mg 6 Ir 2 H 11 is believed to contain both the IrH 4− 5 and the 18-electron IrH 5− 4 anion. [35] Iridium also forms oxyanions with oxidation states +4 and +5. K 2 IrO 3 and KIrO 3 can be prepared from the reaction of potassium oxide or potassium superoxide with ...
The type locality of this iridium anomaly is near Raton, New Mexico. [1] [2]Iridium is a very rare element in the Earth's crust, but is found in anomalously high concentrations (around 100 times greater than normal) in a thin worldwide layer of clay marking the boundary between the Cretaceous and Paleogene periods, 66 million years ago.
Iridium-192 is a very strong gamma ray emitter, with a gamma dose-constant of approximately 1.54 μSv·h −1 ·MBq −1 at 30 cm, and a specific activity of 341 TBq·g −1 (9.22 kCi·g −1). [ 14 ] [ 15 ] There are seven principal energy packets produced during its disintegration process ranging from just over 0.2 to about 0.6 MeV .
