looks like it went fairly well. slight under-performance of one of the engines, but still within test parameters from what i read.

^that is an awesome piece of engineering... they were of course designed to be re-used multiple times on the space shuttle. their new role, however, has the legacy (leftover) engines from the STS program to be mounted on the SLS and used once and not recovered. seems like a shame if you ask me.

I've read a few things about the path forward to when they start production of new expendable versions for SLS. There are 16 currently available RS-25D (SSME)... most leftover from shuttle and one constructed from parts in inventory. This gives enough for a maximum of 4 SLS launches (each one used 4 shuttle engines). anyway the expendable versions are already being thought about. they are just going with the "RS-25" nomenclature (as opposed to going straight to a "RS-25E" expendable version) from now on because it looks like there will be a gradual upgrade towards more efficient manufacturing and using parts optimized for one time use to save weight and cost. A lot of the engineering from the RS-68 (first stage engine for Delta rockets, designed for one time use) is being drawn upon to convert the RS-25 to a more economical, one-use optimized engine for the SLS.

I really want to see them hire anyone with a BS thats not a pilot.

That said, for the expected amount of martian construction I keep seeing for a semi-permanent base, Im surprised they aren't asking for construction workers.

This class will begin training in 2017 for a first mission that won't take place until 2023 and a first mars mission in 2030. 6-13 years is more than enough time for the next class of astronauts to develop any skills necessary. I can't wait to apply even though it will be low odds of making it through.

It is a lot easier to train astronauts to be construction workers than it is to train construction workers to be astronauts.

i dunno... there are some very skilled trade-workers out there that have jobs which take a lifetime to master. i would imagine hiring some of those for the tasks at hand as mission specialists would make sense.

If they have taken a lifetime to master their skilled trade, they would be way too old to start out as an astronaut. Someone with absolutely no background or formal education in science, engineering (outside of structural stuff), astrophysics, orbital mechanics, piloting aircraft, high stress (potentially life threatening) problem solving would simply take too long to train for this kind of thing.

so whats the benefit here? I feel like if it just fell into the water slowly without breaking up it would be just as good as it landing on that platform.

1. Salt water is corrosive as hell.
2. Electrical parts don't do well in the water
3. Vibration damage of being in the water
4. Recovery costs of sending a boat out there, fishing it out of the water, bringing it back
5. You'd most likely lose the ability to reuse the actual engine, but you could probably keep the shell

Man you could feel the pure joy and excitement coming out of that crowd. For most of us space travel and things like this seem sorta routine today, but knowing how difficult that had to have been really gives you chills to watch happen.
