A launch streak captures the liftoff of a SpaceX Falcon 9 rocket carrying several NASA small satellites and instruments from Space Launch Complex 4 East at Vandenberg Space Force Base in California on Monday, March 30, 2026, as part of the company’s Transporter-16 mission. The demonstrations will test thermal protection systems, advance in-space communications, deepen our understanding of Earth's atmosphere, and more to foster capabilities for NASA’s exploration and research goals.

The Lunar Roving Vehicle (LRV) was designed to transport astronauts and materials on the Moon. An LRV was used on each of the last three Apollo missions; Apollo 15, Apollo 16, and Apollo 17, in 1971 and 1972, to permit the crew to travel several miles from the lunar landing site. This photograph was taken during the Apollo 16 mission.
KENNEDY SPACE CENTER, FLA. -- After technicians removed and replaced all of the 32 bearings located in the JEL (jacking, equalization and leveling) cylinders and reinstalled the 16 cylinders on Crawler Transporter No. 2, workers take the crawler for a test run. During routine inspections, technicians found cracks in some of the bearings in the 16 JEL cylinders on the vehicle. There are 16 cylinders and 32 bearings per crawler.

KENNEDY SPACE CENTER, FLA. -- A jacking, equalization and leveling (JEL) cylinder and bearing from Crawler-Transporter No. 2 is lowered by a crane to a position on the ground. During routine maintenance inspections last week, technicians removed two of the 16 JEL cylinders on the crawler to gain access to the bearings and found three of the four bearings cracked. Further eddy current inspections indicated that cracks are present on 15 of the bearings. There are 16 cylinders and 32 bearings per crawler.

This payload canister is being transported to Launch Pad 39A for a "fit check." At a later date, the canister will be used to transport to the pad the S3/S4 solar arrays that are the payload for mission STS-117. The mission will launch on Space Shuttle Atlantis for the 21st flight to the International Space Station, and the crew of six will continue the construction of station with the installation of the arrays. The launch of Atlantis is targeted for March 16.

KENNEDY SPACE CENTER, FLA. -- Perry Becker, an engineer with NASA, points to a crack in a bearing from one of the jacking, equalization and leveling (JEL) cylinders on Crawler-Transporter No. 2. During inspections, technicians removed two of the 16 JEL cylinders on the vehicle to gain access to the bearings for routine maintenance and found three of the four bearings had cracks. Of the three bearings, two had extensive damage. Further eddy current inspections indicate that cracks are present on 15 of the bearings. There are 16 cylinders and 32 bearings per crawler. Although no cause for the cracks is known at this time, engineers are currently evaluating the situation to determine the most appropriate solution.
