Has the Raptor engine changed in its target thrust since the last number we have officially heard of 1.55Mlbf SL thrust?

EDIT: Thanks for the gold!!

Hello Elon, HUGE HUGE fan here!! Question about the Mars Colonial Transporter:

There has been a lot of speculation over comments about exactly how much mass you are hoping to send to the Martian surface with the MCT. Can you tell us how much cargo you would like to be able to land on Mars with MCT, not including the mass of the MCT itself?

We're getting enough new numbers here for a dozen new discussion posts full of math :)

Emily Shanklin indicated in late 2013 that the Raptor would be the first of a "family of engines" designed for the exploration and colonization of Mars. Could you elaborate on her wording, i.e. was she simply referring to a vacuum version and standard version, or do you plan on building multiple methane-based engines with significantly different thrust and size specifications?

Oh my goodness, I am so starstruck. You responded!! Thanks for the information, and thank you so much for responding!! You made my year!!

By the way, might 27 be the number of engines you're talking about? ;)
