What source was used for this article?[edit]

NASA says that the weight of the Apollo Extravehicular Mobility Unit (EMU) was only 85 kg, not 111 kg as stated in this article (see this document, page 12):

The EMU tested on Apollo 9 and used on Apollo lunar missions 11 through 14 weighed about 85 kg (185 lb) fully charged and included three main parts:

A7L Pressure Garment Assembly (PGA), the “man-shaped” part of the EMU

Portable Life Support System (PLSS) backpack connected to the PGA by hoses and harnesses

Oxygen Purge System contingency oxygen supply

Enhanced EMU[edit]

Need to add references to it. Development of it started around 1990 with the first fully functional suit debuting in 1998. The suit used before 1990 became to be known as the "baseline EMU". As far as I can tell the most significant visual change is the life support backpack. —Preceding unsigned comment added by Craigboy (talk • contribs) 04:36, 24 March 2010 (UTC)[reply]

Comparison Section is a mess[edit]

Majority of the ACES information is incorrect, I may fix or just delete the ACES section all together. There's isn't much reason to compare an IVA suit to two EVA suits. And that section of the chart includes info about the Shuttle Ejection Escape Suit and the Launch Entry Suit when it should be just talking about the Advanced Crew Escape Suit.--Craigboy (talk) 12:20, 31 May 2010 (UTC)[reply]

Section has been removed.--Craigboy (talk) 23:14, 26 December 2010 (UTC)[reply]

Various info[edit]

"The Shuttle/ISS EMU was designed and has been operated with a single LEO-based SSA design that utilized the existing helmet from the Apollo A7LB spacesuit."

Weight and layers[edit]

After a recent news item of an Astronaut's spacesuit and some water, then there was a recollection by another ISS astronaut, who's spacesuit literally filled with water. This astronaut explained to the BBC, that there are like 23 layers to the suit, and I think he explained what the approximate weight of each suit was was. -Mardus /talk 07:14, 19 February 2016 (UTC)[reply]
