Columbia on Mobile platform
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. Harperska 02:49, 21 September 2006 (UTC)
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.
There is an error with the ML Designers for the Constallation program
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.
There are other MLPs than the Space Shuttle/Saturn V ones
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.
- Yes, the article currently speaks only of the platform moved by the crawler-transporter. The Atlas, SpaceX Falcon, and other rockets use a type of MLP that moves on rails, and are "powered" by railcar mules (in the case of Atlas and Falcon, they are Trackmobile rail mules). Technically, Sea Launch's Odyssey could be considered an MLP. To me, the proper-noun Mobile Launch Platform will always be the system counterparted with the crawler-transporters. I suppose the question is whether to make a separate mobile launcher platform article about the class, and leave this article about the proper-noun MLP. Another question is whether the Atlas service tower type has its own proper-noun name. I just don't know the answer to that one. — Huntster (t @ c) 06:44, 25 October 2011 (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'm terrible at writing prose in articles, but I'll try later. Basically, yes, there is a fourth MLP that was constructed specifically for the Constellation program. See its category on Commons at commons:Category:Mobile Launcher Platform 1 (Ares I). It will be retained and modified for SLS, and the others are being sold/destroyed. — Huntster (t @ c) 01:13, 4 September 2013 (UTC)
- That's great, Hunster. We can work on it together. You take a first stab at it, getting the basic facts set out, along with citations for the statements. Ping me when you're done and I'll be more than happy to come through and make a copyedit pass. Heck, you could think of it as "specialization and exchange" in the economic sense. You (Huntster) always do such awesome work on the whole Wikipedia image side of things, and have many times helped out big time in an article I was working on (I hate image work as I can never seem to keep in line with all the Byzantine legal and policy rulz about images; not to mention all the techie stuff related to images as well); so I'm happy to help on some copyediting on an article you've been workiing on (and, of course, to improve Wikipedia). Voila, specialization and exchange! N2e (talk) 03:53, 4 September 2013 (UTC)
- Mhmm, it's been on my mind for a while now to write a much more complete history of crawler-transporters as well, but just never find the time to do it. These MLPs could do with some history as well, but as hard as finding material for the CTs have been these guys will be even more difficult. In any case, I can't say how timely I'll be (most of my Wiki time comes during work), but I will ping you when I have something. Images are fun! I'm finally starting to build a decent library of image software, which makes things even better :) — Huntster (t @ c) 04:18, 4 September 2013 (UTC)
Disassembly and Sale section
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)
