In a 2022 interview, Breanne Rohloff, an engineer for NASA contractor Jacobs, described driving the crawler that carries the assembled stack: at a reported 0.8 miles per hour, with the trip taking about four miles and a full eight-hour shift.
Who drives the rocket crawler?
Rohloff told Futurism that she studied engineering at the University of Central Florida, interned at Kennedy Space Center, and joined the crawler team after graduating. The interview identified her as an engineer for NASA contractor Jacobs. Her job was not to assemble the rocket; her team moved the completed vehicle and handled the work around that move.

She summed up the role this way: “We’re like the Space Center’s Uber for rockets.” The 2022 profile described her as 24, but that is an age reported at the time of publication, not a current age.
How big is the crawler, and how long does the trip take?
The Futurism headline calls the crawler a 6.5 million-pound vehicle; Rohloff recalled its weight in the interview as 6 million pounds. Those are two differently attributed figures from the same 2022 coverage, not a single independently verified specification. She said it travels at 0.8 miles per hour.

- ADVANCED MODEL-ROCKET-BUILDING KIT: The Mercury Redstone rocket-building Kit offers kids ages 10+ and rocketeer enthusiasts to build a 1:34 scale replica of Mercury Redstone (MR-4) and Gus Grissom’s Liberty Bell 7. This kit includes the rocket parts, design decals, recovery streamer, and instructions. It requires mini rocket engines, Starters, Recovery Wadding, a launch pad system, and 4 high-quality 1.5-volt AA alkaline batteries for launch use (sold separately).
- SOARS UP TO 200 FT.: Our Mercury Redstone delivers an unforgettable experience from assembly to recovery with a projected altitude of 200 ft. (61 m) using a C6-3 Estes rocket engine (sold separately). It is also compatible with a C5-3 rocket engine.
- READY TO ASSEMBLE: Our advanced rocket kit presents a rewarding challenge that requires advanced building skills and 3+ hours of assembly time. air it with the Estes Porta Pad II Launch Pad with 3/16-Inch Launch Rod and Electron Beam Launch Controller (sold separately) for a successful and educational blastoff experience.
- SAFETY FIRST, FUN ALWAYS: Our rockets and rocket launch accessories are designed to be used with the NAR (National Association of Rocketry) model-rocket safety code. Always ensure you have an appropriate launch site, stand back at least 15 ft., insert the safety key, issue a countdown, and then you can let your rocket fly!
- WE IGNITE IMAGINATIONS: Since 1958, Estes has created educational rocket kits and displays designed for an unforgettable aerospace experience. As a family-owned company, we have grown to offer exciting STEM products that engage aspiring rocketeers and the future minds of aerospace.
Rohloff put the route from the Vehicle Assembly Building to the launch pad at about four miles. She said the move takes a whole eight-hour shift, including picking up the assembled stack, setting it down at the pad, and clearing the pad by backing away. The shift estimate describes the operation, not eight hours of uninterrupted driving.
Why is steering a crawler different from driving a truck?
The crawler’s cab is at the front right, while steering is done from the middle of the vehicle. From the cab, a driver cannot judge its position the way a car driver judges a turn. Rohloff said drivers stand and use fixed visual references along the crawlerway, monitoring the front and rear tracks and making small steering corrections.

She reported that steering is limited to a maximum of six degrees in one direction. At the interview’s reported pace of 0.8 miles per hour, the machine responds slowly, so the driver must anticipate turns and watch how the tracks follow the route. As Rohloff put it: “You’d think a turn wouldn’t sneak up on you, but it will sneak up on you.”
How does the crawler keep the rocket level on a slope?
Rohloff described a system called JEL—jacking, equalizing, and leveling—that keeps the surface carrying the rocket stack level as the crawler climbs the launch-pad slope. In her account, hydraulic cylinders at each corner adjust the platform, and operators watch the system’s limits during the climb.

Driving is only one part of the job. Rohloff described preventative maintenance, corrective maintenance when problems are noticed, and walkdowns before a move. Her account also includes watching for wildlife along the route: she named hogs, coyotes, alligators, tortoises, and mice, and said the team can stop so animals can be moved safely.

The interview’s operational figures and descriptions were published in February 2022 in coverage of planned SLS/Orion operations. They describe Rohloff’s account at that time; they do not establish today’s crawler configuration, staffing, schedule, or procedures. The University of Central Florida also republished the interview at UCF News.
