Space Shuttle Solid Rocket Booster
The Space Shuttle Solid Rocket Booster (SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. A pair of these provided 85% of the Space Shuttle's thrust at liftoff and for the first two minutes of ascent. After burnout, they were jettisoned and parachuted into the Atlantic Ocean where they were recovered, examined, refurbished, and reused. The Space Shuttle SRBs were the most powerful solid rocket motors to ever launch humans. The Space Launch System (SLS) SRBs, adapted from the shuttle, surpassed it as the most powerful solid rocket motors ever flown, after the launch of the Artemis-1 mission. Each Space Shuttle SRB provided a maximum thrust, roughly double the most powerful single-combustion chamber liquid-propellant rocket engine ever flown, the Rocketdyne F-1. With a combined mass of about , they comprised over half the mass of the Shuttle stack at liftoff. The motor segments of the SRBs were manufactured by ...

Outer Space
Outer space, commonly shortened to space, is the expanse that exists beyond Earth and its atmosphere and between celestial bodies. Outer space is not completely empty—it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is . The plasma between galaxies is thought to account for about half of the baryonic (ordinary) matter in the universe, having a number density of less than one hydrogen atom per cubic metre and a kinetic temperature of millions of kelvins. Local concentrations of matter have condensed into stars and galaxies. Studies indicate that 90% of the mass in most galaxies is in an unknown form, called dark matter, which interacts with other matter through gravitational but not electromagnetic forces.

Iuka, Mississippi
Iuka is a city in and the county seat of Tishomingo County, Mississippi, United States. Its population was 3,028 at the 2010 census. Woodall Mountain, the highest point in Mississippi, is located just south of Iuka. History Iuka is built on the site of a Chickasaw Indian village that is thought to have been subordinate to the settlement at Underwood Village. The name ''"Iuka"'' comes from the name of one of the chiefs of the village. Iuka was founded by David Hubbard, a wagon train scout. Euro-American settlers arrived with the Memphis and Charleston Railroad in 1857. Before the American Civil War, the town boasted an all-female college, a boys' military academy, and a fine hotel. The Civil War brought widespread devastation when a major engagement here occurred on September 19, 1862. The Battle of Iuka resulted in 1200 to 1500 killed or wounded. The dead Confederate soldiers were buried in a long trench that eventually became Shady Grove Cemetery. The first normal school bui ...
