This article is lacking an in-depth picture. Here's one of Columbia. Can someone put it in the article? http://www.vesmirweb.net/galerie/raketoplany/ig05_sts107_launch_02.jpg
Does the crawler-transporter stay at the launch pad during launch? Is it well-protected against the blast of the rockets? If the crawler leaves the mobile launcher platform, how is the platform moved off of the crawler? GBC 00:59, 11 September 2006 (UTC)
How is the shuttle held to the pad? What are those tabs that come up to meet the trailing edge of the orbiter's wings?
Clearly this article is in need of an expert. I will give it a stub tag.

From the article on
Nitrogen:
An example occurred shortly before the launch of the first Space Shuttle mission in 1981, when two technicians lost consciousness and died after they walked into a space located in the Shuttle's Mobile Launcher Platform that was pressurized with pure nitrogen as a precaution against fire. The technicians would have been able to exit the room if they had experienced early symptoms from nitrogen-breathing.
ASRC is not designing 3 new MLPs for use during the Constallation Program. They have been contracted to design certain elements of the new Mobile Launcher (which is the actual name of the "platform"). The new ML is being designed by Reynolds, Smith and Hills, Inc., just like the MLP and the LUT were. In fact, the new ML is in construction at one of the parksites next to the VAB, which you can see as you go over the Causeway from Port Canaveral to Merritt Island.
As for the question above, the Crawler-Transporter does not stay at the PAD during launch. The CT acts somewhat like a hydraulic lift when it carrys the MLP and shuttle from the VAB to the PAD. At the parksite, VAB and PAD, 6 mount mechanisms exist that hold the MLP about 22 feet off the groud surface. When the CT gets to the pad, it lowers the MLP onto the Mount Mechanisms. They are precisly located with 6 pins. Only the weight of the MLP holds it in place.

The Atlas V rocket also uses a mobile launch platform (its much smaller). So it would seem that mobile launch platforms are a class of vehicles as opposed to a single design that the article currently infers.

I figured this is a science-related article so I changed the units to metric as per Manual of Style: Units of measurement. Jon ( talk) 02:20, 22 August 2013 (UTC)
Some of the existing prose in the article makes the article scope a bit unclear. The article seems to be about the three MLP's, built and used for some years on multiple different launch systems, and now being sold off by NASA. There is also an SLS section that seems it might be referring to some other/different "Mobile launcher", as it seems this launcher is being saved for reuse on SLS and is therefore not one of the (only?) three MLPs, all of which are apparently being auctioned off by NASA. Anybody have a good handle on this? N2e ( talk) 15:57, 3 September 2013 (UTC)
I think is outdated as it has 2013 dates... IIRC no bids were received but I do not have a cite for that. ++ Lar: t/ c 21:56, 27 March 2014 (UTC)
There are numerous (7) "would have" references under the Constelation section on planned changes to the MLP, but no reason is stated on why they never happened (each paragraph is missing a source). Bassmadrigal ( talk) 20:12, 12 February 2015 (UTC)
Hello fellow Wikipedians,

The section on the Sound Suppression System (SSS) is improperly written.
The Shuttle had a sound suppression system not because the "Crew Cabin" was closer to the engines, but because the SSME took 6 seconds to achieve full power and the vehicle needed to be held down while the twang manuever went past Top Dead Center and rocked back.
That left the entire vehicle exposed to acoustic energy for 6 seconds. Worse, the orbiter was covered in fragile tiles which could be torn off. The SSS was to protect the tiles and vehicle systems from 6 seconds of the acoustic energy, more then cabin crew issues.

With the SLS, NASA seems to dropped the "Platform" from Mobile Launcher, reverting to the Apollo-era term. Should the article be changed to reflect that? Or maybe we can expand the section on the SLS mobile launcher and spin that into a separate article, since the main focus of this one seems to be the MLPs used during Shuttle? - Jadebenn ( talk) 02:03, 7 August 2019 (UTC)
The result of the move request was: Withdrawn by proposer due to unanimous opposition. ( non-admin closure) - Jadebenn ( talk) 09:32, 28 November 2019 (UTC)
It was proposed in this section that multiple pages be
renamed and moved.

– The current name is incorrectly capitalized, not the most common term, and blends two different types of structure together. During the Apollo-era, they were mobile launchers. During the Shuttle-era, they were mobile launch platforms. "Mobile launcher platform" is ambiguous to which configuration is being referred to.
I have documented several examples of NASA referring to these three structures during and after the Shuttle-era as "mobile launch platforms" below:
Here are some examples of third-party organizations calling them by that name:
The ngrams data also clearly shows that "mobile launch platform" is in wider use than "mobile launcher platform."
Given these facts, I believe a move to "Mobile launch platform" is the correct action to take, as it's more in-line with Wikipedia's name policy. - Jadebenn ( talk) 01:41, 24 November 2019 (UTC)
The issue at hand is whether the article should be about the three specific platforms built for the Apollo program and later used for Shuttle, the specific implementation of the "Integrate-Transfer-Launch" concept in the MLs and MLPs of LC-39, or the general concept of a "mobile launcher" or "mobile launch platform" as used by some vertically-integrated rockets. - Jadebenn ( talk) 10:01, 28 November 2019 (UTC)
Found this picture while adding sources to the article. Any thoughts on adding it to the article? PedanticLlama ( talk) 21:56, 10 December 2019 (UTC)
Moved as proposed. BD2412 T 15:33, 19 January 2020 (UTC)
Mobile Launcher Platform → Mobile launcher platform – There was an RfC about whether the scope of the article is about the MLP in general. Since the consensus is reached, the subject is no longer a proper noun. So I propose to de-capitalize the article's title à la mission control center.

—These three articles have same amount of information as the sections of the MLP. Therefore, I suggest to merge the articles into MLP. -- Soumyabrata ( talk • subpages) 10:06, 27 January 2020 (UTC)
The articles Mobile Launcher Platform 1, Mobile Launcher Platform 2, and Mobile Launcher Platform 3 are merged per the above discussion. However, the final thing to do is to convert them into redirects. Unfortunately, I am banned to do so. Therefore, I request to convert the three articles into a redirect to mobile launcher platform. -- Soumyabrata stay at home wash your hands to protect from coronavirus 14:28, 26 March 2020 (UTC)
