KENNEDY SPACE CENTER, FLA. -  Robert T. Nelson of KSC Security points to an approximately 24-foot-long crack on the Mobile Launcher Platform (MLP), which is holding the Space Shuttle Discovery en route to Launch Pad 39A for the STS-82 mission.  Nelson was riding on the MLP when he heard a loud noise and noticed the crack.  Rollout had begun shortly after 7 a.m. EST and was stopped at about 8:25 a.m.  This Y-shaped crack is on the MLP surface and runs from near the left-hand solid rocket booster flame hole toward the near corner of the MLP.  Rollout of Discovery resumed just past noon after structural engineers determined that the integrity of the MLP had not been compromised.  Discovery is scheduled to lift off on the second Hubble Space Telescope servicing mission on Feb. 11.

KENNEDY SPACE CENTER, FLA.  -  Crawler-transporter (CT) number 2, moves away from the Vehicle Assembly Building with a Mobile Launcher Platform (MLP) on top on a test run to the launch pad.  The CT recently underwent modifications to the cab.  The CT moves Space Shuttle vehicles, situated on the MLP, between the VAB and launch pad.  Moving on four double-tracked crawlers, the CT uses a laser guidance system and a leveling system for the journey that keeps the top of a Space Shuttle vertical within plus- or minus-10 minutes of arc.  The system enables the CT-MLP-Shuttle to negotiate the ramp leading to the launch pads and keep the load level.  Unloaded, the CT weighs 6 million pounds.  Seen on top of the MLP are two tail service masts that support the fluid, gas and electrical requirements of the orbiter’s liquid oxygen and liquid hydrogen aft umbilicals.

Moving on four double-tracked crawlers, the CT uses a laser guidance system and a leveling system for the journey that keeps the top of a Space Shuttle vertical within plus- or minus-10 minutes of arc. The system enables the CT-MLP-Shuttle to negotiate the ramp leading to the launch pads and keep the load level. Unloaded, the CT weighs 6 million pounds. Seen on top of the MLP are two tail service masts that support the fluid, gas and electrical requirements of the orbiter’s liquid oxygen and liquid hydrogen aft umbilicals.
CAPE CANAVERAL, Fla. – –  Employees and media gather near Launch Pad 39B at NASA's Kennedy Space Center in Florida for the handover ceremony for Mobile Launcher Platform-1, seen here.  The platform is being transferred from NASA's Space Shuttle Program to the Constellation Program for the Ares I-X flight test targeted for this summer. Constructed in 1964, the mobile launchers used in Apollo/Saturn operations were modified for use in shuttle operations. With cranes, umbilical towers and swing arms removed, the mobile launchers were renamed Mobile Launcher Platforms, or MLPs.  Photo credit: NASA/Kim Shiflett

KENNEDY SPACE CENTER, FLA. -  A high-flying bird takes a closer look at the Mobile Launcher Platform (MLP) number 3 with twin solid rocket boosters bolted to it as it crawls toward Launch Pad 39A, in the background.  The crawler is moving along the crawlerway at various speeds up to 1 mph in an effort to achieve vibration data gathering goals as it travels toward Launch Pad 39A and then returns.  The boosters are braced at the top for stability.  The primary purpose of these rollout tests is to gather data to develop future maintenance requirements on the transport equipment and the flight hardware. Various parts of the MLP and crawler transporter have been instrumented with vibration data collection equipment.

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, Mobile Launcher Platform-3 (MLP), which supported space shuttle Atlantis for its final flight to the International Space Station on the STS-135 mission, is taking its last journey from Launch Pad 39A to the Vehicle Assembly Building (VAB). A massive crawler-transporter positioned under the MLP -- the last mobile launcher platform to launch a shuttle, begins the trek back to the VAB. A water truck leads the way spraying water on the dry crawlerway to reduce dust particles in the air.                     For more than 40 years, the MLPs have traveled between the massive VAB to both launch pads at Launch Complex 39, and then returned to the VAB for future use. MLP-3 was first used to launch Columbia on the STS-32 mission on Jan. 9, 1990. Photo credit: NASA/Kim Shiflett

The two mobile launcher platforms (MLPs) are seen at the MSS park site at NASA’s Kennedy Space Center in Florida on Jan. 4, 2021. One MLP is undergoing crawlerway conditioning – a several month-long project to ensure the path the rocket takes from the VAB to the launch pad is strong enough to support the weight for the upcoming Artemis I launch. The other MLP used during the shuttle program is in the process of being demolished.

KENNEDY SPACE CENTER, FLA. -  United Space Alliance (USA) workers J.D. Wise, left, and Robert Shackelford, with drill, try to stop an approximately 24-foot-long crack from getting any bigger on the Mobile Launcher Platform (MLP), which is holding the Space Shuttle Discovery en route to Launch Pad 39A for the STS-82 mission. Discovery was on its way out to the launch pad when engineers heard a loud bang and noticed that a crack had developed on the MLP. Rollout had begun shortly after 7 a.m. EST and was stopped at about 8:25 a.m.  This Y-shaped crack is on the MLP surface and runs from near the left-hand solid rocket booster flame hole toward the near corner of the MLP.  Rollout of Discovery resumed just past noon after structural engineers determined that the integrity of the MLP had not been compromised.  Discovery is scheduled to lift off on the second Hubble Space Telescope servicing mission on Feb. 11.

KENNEDY SPACE CENTER, FLA.  -Crawler-transporter (CT) number 2, moves away from the Vehicle Assembly Building, with a Mobile Launcher Platform on top, on a test run to the launch pad.  The CT recently underwent modifications to the cab.  The CT moves Space Shuttle vehicles between the VAB and launch pad.  Moving on four double-tracked crawlers, the CT uses a laser guidance system and a leveling system for the journey that keeps the top of a Space Shuttle vertical within plus- or minus-10 minutes of arc.  The system enables the CT-MLP-Shuttle to negotiate the ramp leading to the launch pads and keep the load level.  Unloaded, the CT weighs 6 million pounds.
