VANDENBERG AIR FORCE BASE, Calif. – On Space Launch Complex 2, the Ocean Surface Topography Mission, or OSTM/Jason 2, spacecraft is moved into the mobile service tower for mating with its Delta II launch vehicle. The launch is scheduled for June 20 from Vandenberg Air Force Base. The launch window extends from 12:46 a.m. to 12:55 a.m. PDT. The satellite will be placed in an 830-mile-high orbit at an inclination of 66 degrees after separating from the Delta II 55 minutes after liftoff. The five primary science instruments of the Ocean Surface Topography Mission aboard the Jason 2 spacecraft are dedicated to measuring the height of the ocean surface. These measurements will be used to evaluate and forecast climate changes and improve weather forecasting. The results also are expected to help forecasters better predict hurricane intensity.

KENNEDY SPACE CENTER, FLA. - Space Shuttle Atlantis continues its slow crawl toward the Vehicle Assembly Building from Launch Pad 39B. The rollback was a safety precaution as the area waits for the arrival of Tropical Storm Ernesto. The storm was forecast to be bringing 58-mph to 70-mph winds in the next 24 hours. After this photo was taken, a revised forecast of lesser winds expected from Ernesto and its projected direction convinced Launch Integration Manager LeRoy Cain and Shuttle Launch Director Mike Leinbach to return the shuttle to the launch pad.

KENNEDY SPACE CENTER, FLA. - Viewed from the NASA News Center across the turn basin in the Launch Complex 39 Area, Space Shuttle Atlantis continues its slow crawl toward the Vehicle Assembly Building from Launch Pad 39B. After this photo was taken, the decision was made to return the shuttle to the launch pad. The rollback was a safety precaution as the area waits for the arrival of Tropical Storm Ernesto. The storm was forecast to be bringing 58-mph to 70-mph winds in the next 24 hours. The revised forecast of lesser winds expected from Ernesto and its projected direction convinced Launch Integration Manager LeRoy Cain and Shuttle Launch Director Mike Leinbach to return the shuttle to the launch pad.

VANDENBERG AIR FORCE BASE, Calif. – In the mobile service tower on Space Launch Complex 2, the second half of the fairing moves close to the Ocean Surface Topography Mission, or OSTM/Jason 2, spacecraft to complete encapsulation. The fairing is a molded structure that fits flush with the outside surface of the Delta II upper stage booster and forms an aerodynamically smooth nose cone, protecting the spacecraft during launch and ascent. The launch of the OSTM/Jason-2 is scheduled for June 20 from Vandenberg Air Force Base. The launch window extends from 12:46 a.m. to 12:55 a.m. PDT. The satellite will be placed in an 830-mile-high orbit at an inclination of 66 degrees after separating from the Delta II 55 minutes after liftoff. The five primary science instruments of the Ocean Surface Topography Mission aboard the Jason 2 spacecraft are dedicated to measuring the height of the ocean surface. These measurements will be used to evaluate and forecast climate changes and improve weather forecasting. The results also are expected to help forecasters better predict hurricane intensity.

The Tropospheric Doppler Radar Wind Profiler (TDRWP), located at Kennedy Space Center, is the only instrument of its kind in operation. Consisting of 640 antennae and occupying five acres near the Launch and Landing Facility, the TDRWP operates at nearly 50 MHz. It will be used as a primary instrument to measure upper level winds for NASA’s Artemis missions, which will launch from the Florida spaceport. The instrument has the ability to provide data from 6,000 to 62,000 feet, every five minutes, far outpacing weather balloons.

VANDENBERG AIR FORCE BASE, CALIF. - At Space Launch Complex 2 on Vandenberg Air Force Base in California, the second stage of the Boeing Delta II rocket is now suspended vertically and can be lifted up the service tower for mating with the first stage. The Delta II will launch the National Oceanic and Atmospheric Administration (NOAA-N) spacecraft. After launch, NOAA-N will be renamed NOAA-18 and will provide measurements of the Earth's surface and atmosphere that will be entered into NOAA’s weather forecasting models and used for other environmental studies. Each day, the satellite will send data to NOAA’s Command and Data Acquisition station computers, adding vital information to forecasting models, especially over the oceans, where conventional data is lacking. Launch of NOAA-N is scheduled for May 11, 2005.

The briefing focused on the National Oceanic and Atmospheric Administration's, or NOAA's, Geostationary Operational Environmental Satellite, or GOES-S. The spacecraft is the second satellite in a series of next-generation NOAA weather satellites. It will launch to a geostationary position over the U.S. to provide images of storms and help predict weather forecasts, severe weather outlooks, watches, warnings, lightning conditions and longer-term forecasting. GOES-S is slated to lift off at 5:02 p.m. EST on March 1, 2018 aboard a United Launch Alliance Atlas V rocket.

KENNEDY SPACE CENTER, FLA. - Space Shuttle Atlantis reverses direction and begins rolling back out to Launch Pad 39B. It had been moved off the launch pad due to concerns about the impact of Tropical Storm Ernesto, expected within 24 hours. The forecast of lesser winds expected from Ernesto and its projected direction convinced Launch Integration Manager LeRoy Cain and Shuttle Launch Director Mike Leinbach to return the shuttle to the launch pad Photo credit: NASA/Ken Thornsley

The United Launch Alliance Delta IV Heavy rocket launches NASA's Parker Solar Probe to touch the Sun, Sunday, Aug. 12, 2018 from Launch Complex 37 at Cape Canaveral Air Force Station, Florida. Parker Solar Probe is humanity’s first-ever mission into a part of the Sun’s atmosphere called the corona. Here it will directly explore solar processes that are key to understanding and forecasting space weather events that can impact life on Earth. Photo Credit: (NASA/Bill Ingalls)

A truck with a specialized transporter drives out of the cargo hold of an Air Force C-5 Galaxy transport plane at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida to deliver the GOES-R spacecraft for launch processing. The GOES series are weather satellites operated by NOAA to enhance forecasts. The spacecraft is to launch aboard a United Launch Alliance Atlas V rocket in November.
