ESSA-9, also known as TOS-G, was a meteorological satellite. ESSA-9 replaced the ESSA-7 satellite.
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.
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 (or OT-3) was a spin-stabilized operational meteorological satellite.
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.

IRA - Polish rock band formed in 1987 in Radom by Jakub Płucisz (guitar), Wojciech Owczarek (drums), Artur Gadowski (vocal, guitar), Dariusz Grudzień (bass) and Grzegorz Wawrzeńczuk (keyboards). They gained a wide popularity in Poland in the early nineties, mainly after releasing the "Mój Dom" album, with the hit title song, which was still during their garage and semi-professional days. They also gained some local popularity amongst the Polish-speaking citizens in the United States, where they lived and worked for few months. After signing a professional contract back in Poland, they released a few albums which didn't prove to be commercially successful (except for the "Mój Dom" follow-up, which was "IRA 1993"), and the band disbanded afterwards. Artur Gadowski started a solo career. He opened for Brian May before his show in Warsaw in September 1998. Artur's solo efforts weren't very successful either, and what success he did gain was largely based on the then legendary status of IRA. A few years later the band reunited, and exists up to now. Once again, they have not attained much popularity, but are well-known amongst hard rock fans in Poland (though they play mainly pop-oriented hard rock), and their concerts are selling rather well.
Arma or ARMA may refer to:
(Edgard Scandurra) - 1988
Ouço um grito
Estou calado
Você me complica
Balanço a boca
Tanta farsa, tanto roubo,
Que (??) tomar Coca Cola
Tiro Yankee para cima
Me acertou na testa
(Ouço um grito) Tudo muda é preciso mudar
(Estou calado) Não é fácil o perigo passar
(Você me complica) Sua cegueira mais e mais me complica
(Balanço a boca) Se a sua pose vale mais que a comida
Tanta farsa, tanto roubo,
Que (??) tomar Coca Cola
Tiro Yankee para cima
Me acertou na testa
"Terceiro Mundo vai explodir!
Se tiver de sapato não sobra!"
Pegue essa Arma!
Pegue essa Arma!

Tudo muda é preciso mudar

Balanço a boca
Tanta farsa, tanto roubo,
