Last week we presented GOSAT a.k.a. Ibuki<\/a>, a mission that has as its objective the mapping of carbon dioxide and methane in the Earth\u2019s atmosphere. A similar mission is getting ready to launch on the other side of the Pacific: the Orbiting Carbon Observatory (OCO). OCO is a NASA Earth System Science Pathfinder<\/a> (ESSP) Program mission.<\/p>\n

The mission team includes the Orbital Sciences Corporation<\/a>, the Jet Propulsion Laboratory<\/a>, and Hamilton Sundstrand Sensor Systems<\/a>.<\/p>\n

 <\/p>\n

The atmospheric carbon dioxide (CO2<\/sub>) is an important greenhouse gas. CO2<\/sub> absorbs and traps infrared radiation emitted by the Earth\u2019s surface, preventing it from escaping to space. OCO will provide global CO2<\/sub> measurements from space. The data collected during the mission will help scientists understand the global carbon cycle. This understanding is essential to improve the predictions of future atmospheric CO2<\/sub> increases and its impact on the climate.<\/p>\n

 <\/p>\n

The OCO has a mass of 407 kg. The two GaAs solar arrays will provide 324 W orbit average for the scientific payload onboard. The satellite will use hydrazine thrusters for stabilization while on orbit. The estimated life span for the mission is 24 months.<\/p>\n

 <\/p>\n

The scientific payload includes three spectrometers. The spectrometers can detect what gases are in the Earth\u2019s atmosphere and determine their amounts. The measurements will translate into monthly estimates of atmospheric CO2<\/sub> over 621-square-mile regions of the Earth\u2019s surface. From its sun-synchronous orbit, OCO will map the globe once every sixteen days. These maps will help locate CO2<\/sub> sources and sinks.<\/p>\n

OCO will be placed on orbit by a Taurus XL launch vehicle. Taurus XL is a solid fuel launch vehicle built by the Orbital Sciences Corporation<\/a>. According to the Taurus fact sheet, it provides launch capability for satellites weighing up to 1,590 kg. The range of launch missions supported by Taurus include low inclination low Earth orbit (LEO), polar LEO, sun-synchronous LEO, geo-transfer orbit, and interplanetary trajectory.<\/p>\n

 <\/p>\n

Depending on the configuration, Taurus can have a mass from 69,000 to 77,000 kg and can have a length from 27 to 32 m. <\/p>\n

 <\/p>\n

The mission launch is scheduled for early 2009. The Taurus XL launch vehicle will lift off from Vandenberg Air Force Base, California.<\/p>\n
