Do we cheer for it to go well or go spectacularly caboom?

I still don\'t fully understand rovers landing sequence - but it makes for a compelling argument to adding animated parts to KSP :)

It\'s quite simple, really- Parachutes -> rockets -> thud. Hopefully a soft thud.

I think we should cheer, this is a bit more important than a bunch of boosters exploding and making Jeb happy.

And to think the launcher is part of the same family that launched these.

Not... really.

Pretty much all Atlas V has in common with the original Atlas ICBM family is the name.

To quote Wikipedia\'s summary of the differences:

# The '1.5 staging' technique was dropped on the Atlas III, in favor of a more-advanced RD-180 engine.

# The main-stage diameter increased from 10 feet to 12.5 feet. As with the Atlas III, the different mixture ratio of the engine called for a larger oxygen tank (relative to the fuel tank) compared to western engines and stages.

# First-stage tanks no longer use stainless steel monocoque 'balloon' construction. The tanks are isogrid aluminum and are stable when unpressurized.

# Use of aluminum, with a higher thermal conductivity than stainless steel, requires insulation for the liquid oxygen. The tanks are covered in a polyurethane-based layer.

# Accommodation points for parallel stages, both smaller solids and identical liquids, are built into first-stage structures.

In many ways, the Atlas III ceased to be an 'Atlas' in that it switched from 1.5-stage-plus-kicker staging to conventional staging, but the moment that the lineage was permanently and irrevocably broken, in my opinion, was when the last legacy features--3m diameter and balloon tanks--were dropped. It\'s a wonderful booster, and incredibly capable for its cost... but it ain\'t really the same family as what launched Glenn.
