VANDENBERG AIR FORCE BASE, Calif. – Workers at Vandenberg Air Force Base in California prepare to hoist a solid rocket motor, or SRM, for NASA's Orbiting Carbon Observatory-2, the OCO-2 mission, from a transporter onto a storage chock where it will be kept until needed. The SRMs will be attached to a United Launch Alliance Delta II rocket slated to launch the OCO-2 spacecraft from Space Launch Complex 2 in July. OCO-2 will collect precise global measurements of carbon dioxide in the Earth's atmosphere and provide scientists with a better idea of the chemical compound's impacts on climate change. Scientists will analyze this data to improve our understanding of the natural processes and human activities that regulate the abundance and distribution of this important atmospheric gas.

VANDENBERG AIR FORCE BASE, Calif. – At Vandenberg Air Force Base in California, technicians and engineers prepare a separation system ring that will be attached to NASA's Interface Region Imaging Spectrograph, or IRIS, spacecraft. The separation system will push IRIS away from an Orbital Pegasus XL rocket when the spacecraft reaches its proper orbit after launch. Scheduled for launch from Vandenberg Air Force Base no earlier than June 26, 2013, IRIS will open a new window of discovery by tracing the flow of energy and plasma through the chromospheres and transition region into the sun’s corona using spectrometry and imaging. IRIS fills a crucial gap in our ability to advance studies of the sun-to-Earth connection by tracing the flow of energy and plasma through the foundation of the corona and the region around the sun known as the heliosphere.

Scheduled for launch from Vandenberg Air Force Base no earlier than June 26, 2013, IRIS will open a new window of discovery by tracing the flow of energy and plasma through the chromospheres and transition region into the sun’s corona using spectrometry and imaging. IRIS fills a crucial gap in our ability to advance studies of the sun-to-Earth connection by tracing the flow of energy and plasma through the foundation of the corona and the region around the sun known as the heliosphere.
