An Apollo style mission for Orion??
« on: 04/11/2017 12:45 AM »
This concept from the blog
https://ciudad-futura.net/2016/01/03/nueva-generacion/
is new for me!
Seems a Apollo style mission for Orion/SLS....
You have information about this?

The lander hab module is inflatable? Packed inside SLS it looks lens shaped.

SLS Block IB with Orion can only carry a payload of 10 t into a near rectilinear orbit (NRO). Assuming a dry mass of 5 t, that's only a propellant mass of 5 t. Not enough to get the Lunar surface and back from NRO. The LM would have to be refuelled, with probably another 10 t of propellant.

Wow! i have found that the artwork is a proposal  from Boeing:
( see this PDF booklet)

That concept from ciudad-futura.net won't work. It would take two SLS launches to get Orion and the lander to lunar orbit.

A reusable lunar lander would have to be refueled for the next mission. If a 10 ton fuel module was enough, then repeat missions would only need one SLS flight to send Orion and the lander fuel.

Saturn V could do it with Apollo and LM, but Orion and proposed landers are more capable and more massive. It's going to take two launches.

Apollo relied on the use of the Apollo service module to for lunar orbit insertion, while the Orion service module doesn't have near the same dV capability. Unless the service module of Orion is made larger, an apollo style mission won't work.

The lander would be brought to NRO or DRO by Orion, then proceed to the lunar surface and back on its own. But SLS is too small to launch that type of mission in a single shot.
