@RocketAcademy @Rocketeer_UK I love DARPA as much as the next person, but XS-1 is an unmanned suborbital spaceplane that is a paper design.

@kchangnyt "XS-1 is an unmanned suborbital spaceplane that is a paper design." And those microcomputers are toys that can't run COBOL!1 reply 2 retweets 0 likes -

@kchangnyt And those airplanes can't cross the ocean like dirigibles can! The argument never changes. :-)1 reply 2 retweets 0 likes -

@RocketAcademy If slamming NASA for not having a Mars roadmap, seems also silly to laud nonexistent DARPA paper plane as revolutionary.2 replies 0 retweets 0 likes -

@kchangnyt XS-1 contractors have been working for months; a Orion contractors for years. Millions of $ vs. billions. Silly comparison.1 reply 0 retweets 0 likes -

@RocketAcademy Right. XS-1 contractors have been sketching for months. Northrup has cute model. Ergo space transport revolution.2 replies 0 retweets 0 likes -

@kchangnyt Hardware doesn't materialize overnight. Do you think Orion was built in six months?1 reply 0 retweets 0 likes -

@kchangnyt The Bush Vision of Space Exploration was announced in 2004. Complaining that DARPA hasn't build a Spaceplane in 6 mo seems odd.1 reply 0 retweets 0 likes -

@RocketAcademy I'm not complaining about DARPA. I'm saying it's silly to extrapolate from incomplete paper study to revolution as done deal.2 replies 0 retweets 0 likes -

@kchangnyt Yet, you extrapolate from a suborbital launch of a Sesame Street toy and a rubber duck to NASA astronauts on Mars?2 replies 0 retweets 0 likes
@RocketAcademy Read the whole article I wrote. It points out NASA plans unclear, Orion may be superfluous, could only be part of Mars craft.

@kchangnyt Likely even less than that. If NASA goes to Mars at all.@RocketAcademy0 replies 0 retweets 0 likesThanks. Twitter will use this to make your timeline better. UndoUndo
