The NASA Artemis II mission is targeted for launch as early as Feb.
-
NASA is targeting Sat. Jan 17 for the rollout of the Artemis II SLS rocket and Orion spacecraft for final integration, testing, and launch rehearsals.
The 4-mile journey to the launch pad at KSC using the crawler-transporter-2 will take ~12 hours. After system checks and tests, astronauts will conduct a final walkdown at the pad.
At the end of Jan, NASA will conduct a wet dress rehearsal, including fueling and unfueling of the rocket without astronauts onsite.
@AkaSci My Artemis II launch date predictor tool -- which fits a line to (time remaining until announced launch date) vs. (date of announcement) and calculates the intercept -- is currently predicting 1 April 2026.

May I hitch a lift please? You can drop me off at Luna ...

Knock knock!
It is NASA’s crawler-transporter 2 arriving at the Vehicle Assembly Building at KSC for a pick-up!
Tomorrow morning Jan. 17, at ~7 a.m. EST. it will transport NASA’s Space Launch System (SLS) rocket and Orion spacecraft + Mobile Launcher to Launch Pad 39B in preparation for the Artemis II crewed mission around the Moon on ~6 Feb.
At about one mph, the four-mile journey will take 10-12 hours.

3/nA pair of crawler-transporters (nicknamed “Hans” and “Franz”) were built in 1965 to move the massive Saturn V rocket from Kennedy’s VAB to Launch Complex 39. After the Moon landing and Skylab programs ended, the crawlers were used to transport the space shuttles.
CT-2 was upgraded for the Artemis program around 2012.
CT-1 was originally planned for commercial launch vehicles but its future remains uncertain.https://en.wikipedia.org/wiki/Crawler-transporter

Not sure if I will watch this, but its sure an rare event to see a crawler roll such a huge rocket out of the VAB.

4/n@AkaSci The add-on "Space Shuttle Vessel" for the Orbiter Spaceflight Simulator includes a pretty detailled simulation of the CT, permitting the player to drive the Space Shuttle onto the launch pad (or back again).

4/nHere are a few vital specs of the unique NASA crawler-transporter vehicles. No other vehicle comes close.
Each CT is larger than the size of a baseball infield and powered by locomotive and large electrical power generator engines.
The crawlers are designed to roll underneath the mobile launcher (ML) along with assembled rocket, pick it up, and steadily carry it 4.2 miles to Launch Pad 39B.

The crawler-transporter is able to raise and lower its sides and corners independently using its hydraulic system. It uses its hydraulic suspension to keep the mobile platform and rocket level, as it climbs up the 2.9 degree slope to the the launch pad.

6/nThe NASA crawlers were built by the Marion Power Shovel Co., a manufacturer of steam shovels, power shovels and excavators. Their power shovels played a major role in mining, the construction of the Panama Canal and excavation of Hoover Dam and the Holland Tunnel.
The idea for a crawler-launcher platform started when a NASA engineer visited his father’s farm near Paradise, KY, and observed a giant strip mining shovel in operation.

8/nSome amazing pics of NASA’s massive Artemis II SLS (Space Launch System) rocket and Orion spacecraft, secured to the mobile launcher, inside the Vehicle Assembly Building at KSC, taken on Friday, Jan. 16, 2026.
All work platforms have been retracted in preparation for rollout to Launch Complex 39B at KSC in FL Saturday morning.

@AkaSci How do they move the rocket from the CT to the pad?
From https://www.nasa.gov/wp-content/uploads/2021/04/combined_crawler-transporters_fact_sheet_final.pdf -
"Once the CT-2 makes its eight-hour trek to the pad with engineers and technicians aboard, ML1 and SLS will be lowered onto pad mount mechanisms. After platforms are lowered and power transfers are complete, the CT-2 will roll back down the pad slope and park just outside the pad perimeter gate. CT-2 will wait there until a few days prior to launch in case a rollback is required."
Looking for a video ...

@AkaSci @msbellows I assume the crawler has a leveling mechanism for going up the pad slope while loaded?

@AkaSci How do they move the rocket from the CT to the pad?
@msbellows @AkaSci apparently no truth to the rumor they place a large hot air balloon over Congress, fill it with all the hot air and use that 🤪

@AkaSci @msbellows I assume the crawler has a leveling mechanism for going up the pad slope while loaded?
@pixelpusher220 @msbellows
Independent hydraulic suspensions along sides and corners, raised and lowered to keep the platform level at the pad slope.
