Comments on: The preliminary design for Europe’s service module, to be used with the Orion spacecraft, has come in about a half ton too heavy. https://behindtheblack.com/behind-the-black/points-of-information/the-preliminary-design-for-europes-service-module-to-be-used-with-the-orion-spacecraft-has-come-in-about-a-half-ton-too-heavy/ Tue, 18 Jun 2013 19:23:14 +0000 hourly 1 https://wordpress.org/?v=6.9.4 By: BSJ https://behindtheblack.com/behind-the-black/points-of-information/the-preliminary-design-for-europes-service-module-to-be-used-with-the-orion-spacecraft-has-come-in-about-a-half-ton-too-heavy/#comment-98768 Tue, 18 Jun 2013 19:23:14 +0000 http://behindtheblack.com/?p=23733#comment-98768 In reply to Robert Zimmerman.

No, your math is off. 0.5 metric ton equals 1,104 lbs. It is a half ton in metric, and it is “about” a half ton in English weights, since the metric and English tons are only about 10% different.

That part did they forget to include in the preliminary estimate of weight?

Let me guess. I bet its the airframe itself.

Or 17143 lbs…
