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.

Deep (Silent Running album)

Deep is the third and final studio album from Belfast New Wave/rock band Silent Running, released in 1989.

Background

Despite the commercial failure of the band's 1987 album Walk on Fire and its two singles, the band began to record their second album for Atlantic Records.

Following the release of the Deep album, the band toured extensively after the album's release but split up shortly thereafter, citing a lack of record company support. The band would later reunite for one final performance at Belfast's Empire Music Hall to a capacity crowd in 1998. Reportedly, demos for the unreleased fourth album are widely available although unofficially only.

Like the previous two albums, Deep was a commercial failure.

The album's title is taken from the opening track "Deep in the Heart of Nowhere".

Both "Deep in the Heart of Nowhere" and "Local Hero" were released as promotional singles on CD in America only.

Recording

The first four tracks of the album were produced by the band themselves with Frankie LaRocka and Peter Denenberg, who both engineered the album. The rest of the tracks were produced by John Eden, whilst LaRocka and Deneberg remixed the tracks produced by Eden. The album was LaRocka's first attempt at production work, where he also played drums on part of the album. Originally, LaRocka had signed the band while working in the A&R department at Atlantic Records.

Deep (Niacin album)

Deep is the third studio album from the jazz rock fusion trio Niacin, released in March 2000.

The album is heavily loaded with Billy Sheehan's powerful bass solos and features contributions from guest musicians Glenn Hughes on vocals and Steve Lukather on guitar.

Ten (Pearl Jam album)

Ten is the debut studio album by the American rock band Pearl Jam, released on August 27, 1991 through Epic Records. Following the disbanding of bassist Jeff Ament and guitarist Stone Gossard's previous group Mother Love Bone, the two recruited vocalist Eddie Vedder, guitarist Mike McCready, and drummer Dave Krusen to form Pearl Jam in 1990. Most of the songs began as instrumental jams, to which Vedder added lyrics about topics such as depression, homelessness, and abuse.

Ten was not an immediate success, but by late 1992 it had reached number two on the Billboard 200 chart. The album produced three hit singles: "Alive", "Even Flow", and "Jeremy". While Pearl Jam was accused of jumping on the grunge bandwagon at the time, Ten was instrumental in popularizing alternative rock in the mainstream. In February 2013, the album crossed the 10 million mark in sales and has been certified 13x platinum by the RIAA. It remains Pearl Jam's most commercially successful album.
