Hi there, I'm sorry but I don't have much free time here either, but I would like to volunteer for a mission. Are missions being assigned yet?
I'm sorry but all the missions have been assigned. If you'd like, you can act as backup for a mission by posting here.

Haven't heard much in a while here, what mission is currently 'being flown'?

It appears that Pipcard has completed #5, so PhantomCruiser should now fly #6.

Except that there was no official communicatoin from our Flight Director (Castor) on the matter.

Actually, Artlav is supposed to de-orbit the XR2 first.

That's strange, my mission is still listed as being on "standby". I thought Castor would've noticed the completed mission scenario as well as the mission write-up by now. But he did notice my in-character letter (and gave me a thank for it).

His last activity on the forum was on July 10/11 (depending on your timezone), so maybe he has real life duties to attend to, which is okay. Or maybe not, and that is still okay.

I'm extremely sorry for not being able to get to this earlier. Last Saturday, I was driving home, when a semi rammed into my car as it was crossing an intersection. Fortunately, I escaped with just a pelvic fracture (and one broken arm). I will get back to OFSS as soon as I'm discharged.

Holy smokes Castor. Get well soon dude! Wishing you all the best for a speedy recovery.

Oh, that's just terrible! I hope that you get well soon!

That's awful, Castor. Best wishes.

Man... Some people will do anything to get out of work...

Just kidding dude, sounds like you were very lucky in that collision as it could have been much worse. Get well soon, we can wait.

Get well, Castor.
May there be no lasting injury from this.

Been trying out the missions. Mission 1 was pretty trivial, though fun to watch the launch. I'm currently working through mission 2; doing reasonably well so far. (I left the Themis attached for the first dock to help with visual orientation.) Love the Red Sea in the background of this shot.

I noticed that you could dump about 40% of the scram fuel before takeoff and save yourself some weight (though there's plenty of fuel for the mission.)

Curious if it's normal for the RMS arm to grab the center of mass of the object instead of the exterior of its mesh. It does make it easier to manipulate, but hurts my eyes when it passes through the surface.

I had a curious situation where the node I attached docked to the core module fine, but then kept slowly slipping through the mesh of the core over the next few minutes. I used scenario editor to un-dock and re-dock it and it's fine now.

I did some orbital assembly in KSP. This is actually pretty similar. Fun stuff; thanks again for putting this together Castor!

Good news that you're getting through the missions ok.

Yeah - it's normal, and yeah, assume there's some magic going on there when the arm digs through the million  skin of those modules (and when the arm comes back up leaving no hole)!

I had a curious situation where the node I attached docked to the core module fine, but then kept slowly slipping through the mesh of the core over the next few minutes. I used scenario editor to un-dock and re-dock it and it's fine now.
I wonder if this was an orientation issue? I've always wondered if the port rotation alignment has to be good for a docking, the same as a vessel docking. Good use of the Scenario Editor to complete the dock though.

Finished mission 2. Every time I'd add a module to the first node, it kept shifting through the core mesh again, and I'd have to undock it and redock it. But, no problem, got the station finished.

I de-orbited the XR5 completely unpowered (using Aerobrake), hit the runway a little fast and broke off the landing gear (minor crew injuries), but otherwise everyone's fine. Gotta remember to flare a little bit more on the landing. (Might also have helped to dump my main fuel in orbit, but I wanted a reserve in case I undershot the landing site.)

I've discovered the key to non-spherical gravity is to just wait until the last minute (the preceding orbit or node) to make adjustments.

Nice! You hit the runway! I usually dump most of my fuel shortly after the deorbit burn, that helps a bit, and the XRs can glide quite a bit. I can't count how many times I've broke the gear, all I can say is practice-practice-practice.

##### Scientist
What's the current status on the OFSS IV project? Who's waiting for what?

#### kamaz

##### Unicorn hunter
I think everyone's waiting for Castor to come back. Or for Castor telling us that we can continue without him for now.

Are we waiting now for Artlav (or Athena) to land the XR5?
