In about 48 hours, the ascent vehicle will ferry the lunar samples up for a rendezvous with the orbiter, which will then place the samples into the return capsule and head back to Earth several days later.
Gemini VI-A and VII were a space race triumph for the U.S., and fulfilled much of two major program objectives needed for success with Apollo: rendezvous and long duration. After these missions, the Moon seemed closer.

Even after about a four month experience with the original game before I got ksp2, I still do not understand how to rendezvous. I need help on understanding how to do it, because I feel like its a skill I have been lacking for a while now. I can do landing rendezvous easily, just got to get your craft's trajectory almost right next to the icon on the surface. However, orbital rendezvous seems... complicated. Could anyone give me a simple demonstration weather it be by video, image, or text? It would be a huge help.
Okay.. ill try do it in text, if that doesnt help you ill make a guide with pictures.
Lets say you want to rendezvous with a target that orbits a perfect 100.000 km flat.. This is how you rendezvous with it:
A. Get your rocket into orbit with either your AP or PE at 100km to intersect target orbit.
B. Make sure your Descending Node (DN) is 0.0 to the target. - You do this by manipulating Normal and Anti-Normal.
C. Now raise your AP to 150-200km and keep your PE at 90-100km - This will make your orbit longer than the target and therefore make your 1A - 1B and 2A - 2B (the position of your ship and target when the two orbits intersect) change with every orbit, as the target will do more revolutions around the planet than you during the same time.
D. Wait.. - Yeah. now you just wait the amount of revolutions it takes for your 1A and 1B or 2A and 2B to be relatively close.
E. You have successfully waited and now your 1A and 1B is close enough to make a maneuver. You now wanna manipulate the blue maneuver node: Radial in/Radial out. to correct 1A and 1B to be on top of each other.
F. Time warp until your 20km off the target. Then make a new maneuver node manipulating the blue node (Radial in/radial out) to match the orbit of the target, and manipulate the green node (prograde/Retrograde) to break = Lower your AP - WHILE making sure your A1 and B1 dont drift a part.
G. Now use your RCS thrusters and or careful boost to correct your last maneuvering.
Keep in mind. When you use the RCS thrusters - it is not necessarily best practise to use "aim at target" as you will create movement towards prograde, normal and radial that you have to cancel later. At this stage.. just look at your target. Are you gaining on it? Burn retrograde with your RCS thrusters to break. Is the target moving up down? Burn Radial out/in to make it stand still in frame. Is it moving left to right? Burn Normal anti-normal.
When you are under a 1000m from your target it gets a lot easier to see how your movement is compared to the target. Here your goal is just to make the target not move, left right up down to you.. and if you can, move closer slowly. When you are within 100m you will start maneuvering to the point were you can dock.
You can also use the ] or å (if you have a danish keyboard) to take control of the target.. set the docking port on your rocket as target and make it point to it with the SAS not the RCS.. they will make the two dance around each other. This will make it easier to make sure your craft and targets docking ports are pointing at each other.
Oh and lastely... NEVER approach the target with "Target" and RCS thrusters on.. for some reason.. the micro adjustments the craft keep doing will push you around and make your dance around it...
If you use "target" and "anti-target" press it. have the craft align. then press the "Stability off" and burn towards the target. Do your own changes left right up down. (without rolling and pitching)
In the context of Torch Distributed Elastic we use the term rendezvous torefer to a particular functionality that combines a distributedsynchronization primitive with peer discovery.
Nodes performing rendezvous will all block until the rendezvous is consideredcomplete - this happens when at least min total number of nodes have joinedthe rendezvous barrier (for the same job). This also implies the barrier is notnecessarily of fixed size.
Torch Distributed Elastic rendezvous is designed to tolerate node failuresduring the rendezvous process. Should a process crash (or lose networkconnectivity, etc), between joining the rendezvous and it being completed, thena re-rendezvous with remaining healthy nodes will happen automatically.
A node can also fail after it has completed (or has been observered by othernodes to have completed) the rendezvous - this scenario will be handled by theTorch Distributed Elastic train_loop instead (where it will also trigger are-rendezvous).
Torch Distributed Elastic comes with the DynamicRendezvousHandlerclass that implements the rendezvous mechanism described above. It is a backend-agnostic type that expects a particular RendezvousBackend instanceto be specified during construction.
C10dRendezvousBackend: Uses a C10d store (by defaultTCPStore) as the rendezvous backend. The main advantage of using a C10dstore is that it requires no 3rd-party dependency (such as etcd) to establisha rendezvous.
is_closed() and set_closed() have semantics of eventualpropagation and should not be used for synchronization. The intention isthat if at least one node decides the job is finished, it will close therendezvous, and other nodes will soon observe this and stop running aswell.
A boolean value indicating whether this backend instancewill host the C10d store. If not specified it will beinferred heuristically by matching the hostname or the IPaddress of this machine against the specified rendezvousendpoint. Defaults to None.
Note that this configuration option only applies totorch.distributed.TCPStore. In normalcircumstances you can safely skip it; the only time whenit is needed is if its value cannot be correctlydetermined (e.g. the rendezvous endpoint has a CNAME asthe hostname or does not match the FQDN of the machine).
Implements atorch.distributed.elastic.rendezvous.RendezvousHandler interfacebacked bytorch.distributed.elastic.rendezvous.etcd_rendezvous.EtcdRendezvous.EtcdRendezvousHandler uses a URL to configure the type of rendezvous touse and to pass implementation specific configurations to the rendezvousmodule. The basic etcd rendezvous configuration URL looks like the following
Running heroku console --app AppName in my local terminal I got: ENOTFOUND: getaddrinfo ENOTFOUND rendezvous.runtime.heroku.com. This happened when I was trying to access our production app, but I also got the same response when trying to access the console on any of our Heroku development servers.
Background: The management of gallbladder stones (lithiasis) concomitant with bile duct stones is controversial. The more frequent approach is a two-stage procedure, with endoscopic sphincterotomy and stone removal from the bile duct followed by laparoscopic cholecystectomy. The laparoscopic-endoscopic rendezvous combines the two techniques in a single-stage operation.
Objectives: To compare the benefits and harms of endoscopic sphincterotomy and stone removal followed by laparoscopic cholecystectomy (the single-stage rendezvous technique) versus preoperative endoscopic sphincterotomy followed by laparoscopic cholecystectomy (two stages) in people with gallbladder and common bile duct stones.
Selection criteria: We included randomised clinical trials that enrolled people with concomitant gallbladder and common bile duct stones, regardless of clinical status or diagnostic work-up, and compared laparoscopic-endoscopic rendezvous versus preoperative endoscopic sphincterotomy procedures in people undergoing laparoscopic cholecystectomy. We excluded other endoscopic or surgical methods of intraoperative clearance of the bile duct, e.g. non-aided intraoperative endoscopic retrograde cholangiopancreatography or laparoscopic choledocholithotomy (surgical incision of the common bile duct for removal of bile duct stones).
Main results: We included five randomised clinical trials with 517 participants (257 underwent a laparoscopic-endoscopic rendezvous technique versus 260 underwent a sequential approach), which fulfilled our inclusion criteria and provided data for analysis. Trial participants were scheduled for laparoscopic cholecystectomy because of suspected cholecysto-choledocholithiasis. Male/female ratio was 0.7; age of men and women ranged from 21 years to 87 years. The run-in and follow-up periods of the trials ranged from 32 months to 84 months. Overall, the five trials were judged at high risk of bias. Athough all trials measured mortality, there was just one death reported in one trial, in the laparoscopic-endoscopic rendezvous group (low-quality evidence). The overall morbidity (surgical morbidity plus general morbidity) may be lower with laparoscopic rendezvous (RR 0.59, 95% CI 0.29 to 1.20; participants = 434, trials = 4; I = 28%; low-quality evidence); the effect was a little more certain when a fixed-effect model was used (RR 0.56, 95% CI 0.32 to 0.99). There was insufficient evidence to determine the effects of the two approaches on the failure of primary clearance of the bile duct (RR 0.55, 95% CI 0.22 to 1.38; participants = 517; trials = 5; I = 58%; very low-quality evidence). The effects of either approach on clinical post-operative pancreatitis were unclear (RR 0.29, 95% CI 0.07 to 1.12; participants = 517, trials = 5; I = 24%; low-quality evidence). Hospital stay appeared to be lower in the laparoscopic-endoscopic rendezvous group by about three days (95% CI 3.51 to 2.50 days shorter; 515 participants in five trials; low-quality evidence). There was very low-quality evidence that suggested longer operative time with laparoscopic-endoscopic rendezvous (MD 34.07 minutes, 95% CI 11.41 to 56.74; participants = 313; trials = 3; I = 93%). The Trial Sequential Analyses of operating time and the length of hospital stay indicated that all the trials crossed the conventional boundaries, suggesting that the sample sizes were adequate, with a low risk of random error.
