T O P I C R E V I E WObviousmanLooking through some images, I notice that the forward hatch on LM-5 (A11) and LM-6 (A12) is pained / covered in two colours, split vertically down the centre of the hatch. Later LMs did not have this.Does anyone know why there was a colour difference / what is was used for, and why it was removed?spaceukCan you provide NASA image numbers so we can share the views and comment?At a guess - without recourse to my files as I'm at work - it would be to do with the later science-orientated missions. The hatch may have been made 'lighter' to shave some extra pounds for the science kit ?PhillspaceukObviousmanYou can see it here: http://www.hq.nasa.gov/office/pao/History/alsj/a11/as11-44-6574.jpg and here: http://www.hq.nasa.gov/office/pao/History/alsj/a11/as11-44-6598.jpg and here: http://www.hq.nasa.gov/office/pao/History/alsj/a11/as11-40-5866.jpg on LM-5and here: http://www.hq.nasa.gov/office/pao/History/alsj/a12/AS12-46-6727.jpg and here: http://www.hq.nasa.gov/office/pao/History/alsj/a12/as12-46-6729.jpg on LM-6.But not here: http://www.hq.nasa.gov/office/pao/History/alsj/a16/as16-118-18894.jpg or here: http://www.hq.nasa.gov/office/pao/History/alsj/a16/as16-116-18579.jpg on LM-11 (A16).I presume it was a change made to the J-series LMs, but I can't find anything that tells me what it was and why.TomI was just looking at a couple of photos of Antares (Apollo 14) on the surface, and even though it wasn't a "J" mission, the hatch does not look like Eagle or Intrepid but does look like Orion.PhilipObviousman ... Also take a look at this LM webpages; http://users.specdata.com/home/pullo/ Best regards!Philip http://mars-literature.skynetblogs.be/ Obviousmanyep, I tried there but no luck. I have sent to creator an e-mail, and hope that they might have the expertise to answer the question.Thanks for your help!spaceukAnother guess is that maybe it was a ' test' to see which of the two schemes operated best on the first couple lander missions?Phillspaceuk
