OSIRIS-REx Asteroid Sample Return

[Bev7787]

Changed my entry to stock- built a decent Atlas V 411 as well, was also going to do a launch tower as well but gave up on it. I'm testing my replica now.

Remember nothing is due until actual launch +30 days, so no earlier than October 8.  This allows people to use actual launch audio and to mimic the actual launch timeline, should anyone wish to.  Until then, no entry is considered final.

So I had more time than I thought... Video making time then! Also, how many parachutes does the return capsule have?

1 Drogue and 1 main.  Just like Stardust.

Cool.  Did you notice that Dante Lauretta, PI of OSIRIS-REx (basically my boss) commented on your video:

 

haha no I didn't. Thanks for the notice.

 

I hope you don't get in trouble for playing so much KSP  

Although admittedly, I do it at work all the time too. I'm a full time math teacher and convinced my principal to give me free reign in using KSP to teach concepts.

No, I play on my own time.  And not that much lately.  

But I compliment your strategy:

"To be fair, my job at NASA was working on robots and didn't actually involve any orbital mechanics. The small positive slope over that period is because it turns out that if you hang around at NASA, you get in a lot of conversations about space." https://xkcd.com/1356/

The Atlas V 4-m fairing has arrived at KSC.  Here is an image the fairing half with the logos.

i will do this challenge to modded of course

Trust me you will like it

P.S i made in an earlier version and Mercury-Atlas LV replica 1@1/2 Stage included

 

 

P.SS Just between you and me Ionstorm i am planning on becoming a NASA/JPL Spacecraft engineer when i grow up

i will be 18 in March Next Year

[Bev7787]

I found an article in an All about Space annual on the mission with a concept artwork, mind if i post here?

If you're good you should consider becoming a NASA/GSFC engineer.  (There is a little rivalry between JPL and Goddard, where I work and from where OSIRIS-REx is managed.)

Please do.

Hey Ion storm 

I got a question 

I know liquid Hydrogen in the Centaur Boils off over time what would that boil off equevalent if you converted LH2 Loss to liquid fuel units loss per hour, Day Ect

Because if i use my centaur upper stage to Enter Eve orbit i want to know how much IRL Dv i would have left

to make the mission More Realistic

For OSIRIS-REx, the Centaur is only used for the first 40 minutes (see below image from a NASA Social).  After that only the monoprop engines on the spacecraft are used, so LH2 boiloff is not a big problem.

Got that'

But what i said IF you were to use the centaur in deep space how long would it take to lose all of the LH2 for in my case 

Deep space maneuvers

Ah, a hypothetical based on a launch system doing something it wasn't designed to do.  According to this http://www.ulalaunch.com/uploads/docs/Published_Papers/Upper_Stages/CentaurUpperstageApplicabilityforSeveralDayMissionDurationswithMinorInsulationModificationsAIAA20075845.pdf it could be modified with 100 pounds of extra insulation to reduce boiloff to 1%/day.

Thanks a Bunch 

You want pictures of My Atlas 441 Replica to Blast OSIRIS-Rex to it destination

Sure.

Here are the Pictureshttp://imgur.com/a/rAZWE

Be warned this replica is very low detail but has the same airframe as the real thing and functional like the real thing

Our rocket has arrived.

Those are really great photos!  Thanks for sharing them with us.

And that's a very literal interpretation of "ULA vehicles only."  

[Majorjim!]

I am very tempted to make a replica of this mission but I am busy with a curiosity replica (Just finished the Centaur upper for it) and someone from an Academy of aerospace quality is waiting for my Constellation mission craft for a conference talk in September (fingers crossed they like and use it) so I am very busy in KSP.

 If you folks are still about in a few months I will start it. I have all the reference pictures and info I need now.

Do it, man! I'm working on getting my computer set up, but as soon as I have one I'm gonna start on this. You've got some good competition here, both stock and modded.

IIRC, the competition ends 30 days after the launch. The window is from September to October, but you'll want to check with @IonStorm about that.

OOH ok! I will have a look at the current submissions. It would be for stock KSP, tenth scale bodies ect.

I think that's mostly OK, but there might have been a asteroid that you needed to install, or rendezvous with a stock one.

I would of course make it fully mission capable and fly the mission myself too.
