Crawler No. 2 will be used to move the STS-116 stack from VAB high bay 3 to high bay 2 and crawler No. 1 will be used to transport Atlantis to high bay 3. The rollback will be determined by the mission management team based on information about Hurricane Ernesto and its path through Florida.

The Space Shuttle Columbia stands poised in the night for the STS-83 Microgravity Science Laboratory-1 (MSL-1) mission after the Rotating Service Structure of Launch Pad 39A has been moved back prior to the start of fueling operations that take place about 12 hours before liftoff. During the scheduled 16-day STS-83 mission, the MSL-1 will be used to test some of the hardware, facilities and procedures that are planned for use on the International Space Station as well as research in combustion, protein crystal growth and materials processing experiments

KENNEDY SPACE CENTER, FLA. -- Workers at Launch Pad 39A check the fittings on the payload bay of Endeavour before the bay doors close. The view is looking down into the payload bay. The Shuttle is poised for launch on mission STS-111, Utilization Flight 2, carrying supplies and equipment to the International Space Station. The payload includes the Multi-Purpose Logistics Module Leonardo, the Mobile Base System, which will be installed on the Mobile Transporter to complete the Canadian Mobile Servicing System, and a replacement wrist/roll joint for Canadarm 2. Also part of the mission, Expedition 5 will travel to the Station as the replacement crew for Expedition 4, who will return to Earth aboard the orbiter. Launch is scheduled for May 30, 2002

KENNEDY SPACE CENTER, Fla. -- The GOES-M satellite is poised for flight at Launch Complex 36-A, Cape Canaveral Air Force Station, after rollback of the Mobile Service Tower. GOES-M is the last in the current series of advanced geostationary weather satellites in service. GOES-M has a new instrument not on earlier spacecraft, a Solar X-ray Imager, which can be used in forecasting space weather and the effects of solar storms. The satellite is scheduled to launch atop an Atlas rocket on July 23 during a window that extends from 3:02 to 4:26 a.m. EDT

At Vandenberg Air Force Base in California, the gantry rolls back at Space Launch Complex 2 in preparation for the liftoff of the Joint Polar Satellite System-1, or JPSS-1, spacecraft. The United Launch Alliance Delta II rocket now is poised to boost the satellite to a polar orbit. Built by Ball Aerospace and Technologies Corp. of Boulder, Colorado, JPSS is the first in a series four next-generation environmental satellites in a collaborative program between NOAA and NASA. The satellite is scheduled to liftoff at 1:47 a.m. PST (4:47 a.m. EST), on Nov. 14, 2017.

CAPE CANAVERAL, Fla. -- In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, an overhead crane is poised over the Alpha Magnetic Spectrometer, or AMS, to lift the Payload Attach System, or PAS, up to the AMS. The PAS provides a method of securely connecting the payload to the International Space Station. AMS, a state-of-the-art particle physics detector, is designed to operate as an external module on the International Space Station. It will use the unique environment of space to study the universe and its origin by searching for dark matter. AMS will fly to the station aboard space shuttle Endeavour's STS-134 mission targeted to launch Feb. 26, 2011. Photo credit: NASA/Jack Pfaller

A SpaceX Falcon 9 rocket and Crew Dragon spacecraft stand poised for launch at historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida on May 30, 2020, ahead of the agency’s SpaceX Demo-2 mission to the International Space Station. Liftoff occurred at 3:22 p.m. EDT. NASA astronauts Robert Behnken and Douglas Hurley are the first astronauts to launch from U.S. soil to the space station since the end of the Space Shuttle Program in 2011. Part of NASA’s Commercial Crew Program, this will be SpaceX’s final flight test, paving the way for the agency to certify the crew transportation system for regular, crewed flights to the orbiting laboratory.

CAPE CANAVERAL, Fla. -- A United Launch Alliance Atlas V 401 rocket is poised for liftoff from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida, carrying NASA's Tracking and Data Relay Satellite-K, TDRS-K, to orbit. Launch is set for 8:48 p.m. EST. The TDRS-K spacecraft is part of the next-generation series in the Tracking and Data Relay Satellite System, a constellation of space-based communication satellites providing tracking, telemetry, command and high-bandwidth data return services.

A rising sun illuminates the coastal waters beyond Space Shuttle Endeavour, poised for launch on Nov. 30 at about 10:06 p.m. EST on mission STS-97. On the left, extending toward the orbiter, is the orbiter access arm. The mission to the International Space Station carries the P6 Integrated Truss Segment containing solar arrays and batteries that will be temporarily installed to the Unity connecting module by the Z1 truss, recently delivered to and installed on the Station on mission STS-92. The two solar arrays are each more than 100 feet long. They will capture energy from the sun and convert it to power for the Station. Two spacewalks will be required to install the solar array connections
