ESSA-9

ESSA-9, also known as TOS-G, was a meteorological satellite. ESSA-9 replaced the ESSA-7 satellite.

Launch & orbit

The ESSA-9 was launched on a three stage Delta rocket from Cape Canaveral, Florida. The launch occurred at 07:47 UTC (02:47 EDT) on 26 February 1969. The spacecraft was placed in a sun-synchronous orbit of 101.4° inclination. Immediately after launch ESSA-9 had a perigee of 1,427.0 kilometers (886.7 mi) and an apogee of 1,508.0 kilometers (937.0 mi), giving it an orbital period of 115.2 minutes, or a mean motion of 12.5 orbits per day.

Spacecraft

The ESSA-9 spacecraft was similar to the TIROS series of satellites, having an 18-sided polygonal shape that measured 42 inches (110 cm) in diameter and 22 inches (56 cm) high. It weighed 320 pounds (150 kg). The body of the ESSA-9 was made of aluminum alloy and stainless steel. The shell of the craft was covered with 10,020 solar cells. The solar cells recharged the 63 nickel–cadmium batteries during the time the spacecraft was in sunlight. The ESSA-9 employed the same cartwheel-style stabilization as the TIROS-9 satellite. The satellite used a Magnetic Attitude Spin Coil (MASC) to control its attitude while in orbit. The magnetic field induced by the MASC's current interacted with the earth's magnetic field to provide the torque necessary to maintain a desired spin rate of 9.225 rpm.

ESSA-1

ESSA-1 (or OT-3) was a spin-stabilized operational meteorological satellite.

Launch

ESSA-1 was launched on 3 February 1966 at 07:41 UTC. It was launched atop a Delta rocket from Cape Canaveral, Florida. The spacecraft had a mass of 304 kilograms (670 lb) at the time of launch. ESSA-1 had an inclination of 97.91°, and an orbited the earth once every 100 minutes. Its perigee was 702 kilometers (379 nmi) and apogee was 845 kilometers (456 nmi).

ESSA-1 had a similar design to that of the TIROS satellite series. It was an 18-sided right prism, measuring 107 centimeters (42 in) across opposite corners and 56 centimeters (22 in). It had a reinforced baseplate, which carried most of the subsystems and a cover assembly (hat). ESSA-1 had approximately 10,000 1-cm by 2-cm solar cells, which charged 21 nickel–cadmium batteries. ESSA-1 was designed to take pictures of daytime cloud cover, record them and transmit them when it was in range of a ground acquisition station.

The satellite spin rate and attitude were determined primarily by a Magnetic Attitude Spin Coil (MASC). The MASC was a current Carrying coil mounted in the cover assembly. The magnetic field induced by the coil interacted with that of the Earth's magnetic field, and provided the necessary torque to maintain a desired spin rate of 9.225 revolutions per minute (rpm). Five small solid-fuel thrusters mounted on the baseplate provided a secondary means of controlling the spin rate.

Shooter (drink)

A shooter is a neologism for an alcoholic mixed drink that contains 30 millilitres (1.0 US fl oz) of two or more spirits. Some shooters also have a non-alcoholic ingredient. They are generally drunk quickly, rather than being sipped.

Shooters can be shaken, stirred, blended, layered, or simply poured. Shot glasses or sherry glasses are the usual drinkware in which shooters are served. They are most commonly served at bars, and some bartenders have their own "signature" shooter.

The ingredients of shooters vary from bartender to bartender and from region to region. Two shooters can have the same name but different ingredients, resulting in two very different tastes.

Shooting (bridge)

Shooting is an approach in bridge to the bidding or play of a hand which aims for a favorable result by making a choice that is slightly against the odds. A player might decide to shoot toward the end of a pairs game, when he judges that he needs tops to win, not just average-plus results.

Shooting is generally considered an ethical maneuver when it is used sparingly in an attempt to improve one's score. It is regarded as contrary to the proprieties if a player, perhaps angry with his partner, starts bidding and playing every hand in ways that disregard winning technique.

In contrast, a player who is shooting makes a bid or play that is only slightly inferior, in the hope that the cards lie in such a way that the normal, percentage action will lose. In the long run, even slightly inferior actions lose to the better bid or play, so it is not sensible to shoot unless the only hope left is an unusual situation, such as a 4-1 instead of a 3-2 trump break, or a normal 3NT contract that goes down on normal play.

Shooting sport

A shooting sport is a competitive sport involving tests of proficiency (accuracy and speed) using various types of guns such as firearms and airguns. Hunting is also a shooting sport, and indeed shooting live pheasants was an Olympic event (albeit only once, in 1900). The shooting sports are categorized by the type of firearm, targets, and distances at which the targets are shot.

History

The National Rifle Association of the United Kingdom (NRA) was founded in 1860 to raise the funds for an annual national rifle meeting "for the encouragement of Volunteer Rifle Corps and the promotion of Rifle-shooting throughout Great Britain".

For similar reasons, concerned over poor marksmanship during the American Civil War, veteran Union officers Col. William C. Church and Gen. George Wingate formed the National Rifle Association of America in 1871 for the purpose of promoting and encouraging rifle shooting on a "scientific" basis. In 1872, with financial help from New York state, a site on Long Island, the Creed Farm, was purchased for the purpose of building a rifle range. Named Creedmoor, the range opened in 1872, and became the site of the first National Matches until New York politics forced the NRA to move the matches to Sea Girt, New Jersey. The popularity of the National Matches soon forced the event to be moved to its present, much larger location: Camp Perry. In 1903, the U.S. Congress created the National Board for the Promotion of Rifle Practice (NBPRP), an advisory board to the Secretary of the Army, with a nearly identical charter to the NRA. The NBPRP (now known as the Civilian Marksmanship Program) also participates in the National Matches at Camp Perry.
