First:
Also, you wouldn't be able to do all of those things in one post, and would likely have to break it up a bit. Something like this: 1 post for the launch and stabilized orbit, and 1 post for adjusting your orbit and launching other satellites (or your lunar flyby) and returning. A lunar flyby, due to the distance, would take at least two posts to complete (including the return).
Second:
2. You still have to do an RP for the launch of your rocket, it doesn't just end up in space. Though since you've already done the testing, you can skip the 3 posts for testing it before launch, provided it is the same rocket. You still need to do the three posts for testing before launching your light rocket, as it is different than your heavy one.
3. If your rockets are reusable like you've mentioned, I would like to see a post between each launch detailing the servicing of the rocket to ensure it is still launch worthy.
4. If reusability has not yet been proven, as implied in your posts, then you will need another set of posts to build another rocket for use for each RP. As well as a set of posts to analyze and assess the launch, to determine if you can reuse the rocket (for reusability). This is before the second launch is done. However, from my understanding the reusability of the component that went into space would be more limited, due to the stress caused by reentry. At the very least it would require some repairs and such before it could be reused.
5. How large are these satellites, and how much space is there aboard these rockets? As this will also influence how many you can launch at once. If you want your satellites to have the capabilities you imply, then it is likely that they will be larger satellites, and as such will take up more space in your rocket's bay. Thus limiting the number you can launch at one time.
For instance, the Falcon Heavy has a bay height of 13m and a diametre of 5m. Using the Galileo Satellites as an example to compare with your GNSS MAGIC satellites, they have dimensions of 2.5m by 1m. Meaning if your bay size is similar to the Falcon Heavy (and it would not make sense for it to be much larger, realistically), you could fit maybe ten of those satellites inside. This is because you will also need an additional contraption inside the bay to hold the satellites together during launch, and to assist in the deployment of them once in orbit.
6. With regards to orbits, this will also influence how many you can send into orbit at a single time. If you want multiple satellites at GEO (geo-stationary orbit), you will have to use multiple launches, as the speed and altitude for these orbits are fixed, so you can not easily adjust the location for each satellite. If you want LEO (low earth orbit), this is more easily doable, but you each satellite will still need to be at different heights or angles if done in the same launch. Again, the same for polar orbits. It would cost a lot of fuel and resources to go from LEO to GEO or to polar, which would, again, make that unfeasible.
Third (since you posted while I was writing this):
Sending satellites to the moon and/or sun orbit are going to be more expensive, take more time, and require more work overall. It is also not very feasible to launch them all as part of one launch, due to their relatively different required orbits.
Please provide details of CaliSTARS and MAGIC. But, as mentioned, first you're going to have to do the RP to actually develop the satellites.
It's also worth noting that the max payload weight changes the further out you go, due to the increase in required fuel to reach those distances.
First:
So, this isn't realistically feasible. The amount of fuel you would need to launch multiple satellites, then put them in different orbits, and then do a lunar flyby on top of that, would make your space craft exorbitantly expensive, and way to large to be feasible. To put it in perspective, you have to have enough fuel to launch the rocket into space, which goes up the more weight you have on board (ie satellites), have enough fuel to stabilize your orbit, have enough fuel to change your orbit and restabilize it (then repeat that step for each updated orbit), have enough fuel to do your lunar flyby, and finally have enough fuel to slow your approach again so you don't burn up on reentry. Realistically, you can probably pick two of those things to be done in one launch - a (one) satellite deployed in orbit, and a lunar flyby, OR several satellites in various orbits. That said, those satellites would likely be in relatively similar orbits.NCR wrote: ↑Fri Apr 14, 2023 11:03 am The HB circularizes its first LEO orbit, deploying the first test satellite.
After a series of hohmann transfers, the HB circularizes various orbits at different altitudes, deploying one test sat per each.
Finally, a lunar fly-by is planned and exectuded, ending in a controlled Earth-reentry.

Second:
1. I haven't seen any info about the development for your satellites in your thread. You'll need to include this info before you launch them.NCR wrote: ↑Fri Apr 14, 2023 11:36 pm As the HB passes through the last atmospheric vestiges, more and more stars become visible.
The deployment of a constellation is a tricky affair; let alone two. Various maneuvers are carried in LEO to deploy the CaliSTARS satellites. Of course, a good portion of satellites will have to make significant orbital maneuvers with the on-board propulsion to adjust their orbits into the desired ones; but the HB deploys the sats so to minimize this need, as much as possible.
After all the CaliSTARS sats are deployed the HB raises its altitude, repeating the deployment process for the MAGIC satellites, which of course will also have to position themselves in the right orbit with their propulsion.
After deploying all the sats, a controlled de-orbit is executed to bring back the remaining stage of the HB.
After this public, great success, a press conference is held to announce to the world the commercial avaiability to purchase launches, especially with the cheap and flexible LB; but if, for some reason, the huge payload of the HB should be needed, it is noted that launches with the HB will be, of course, avaiable for purchase too.
Also, a service to design custom-needs commercial sats (within standardized parameters) will be avaiable for purchase if a launch (or part of its payload) is bought, to quicken up the kickstart of the launchers service and to make it more affordable (and thus palatable) for more customers.
Various NCR companies, especially in the tech, TC, and similar sectors, already rush to buy the first avaiable spots after the announcement.
As such, plans are made to expand the manufacturing, so to be able to manage more orders quicker.
Simultaneously, SANC works to implement the reusability features, to cut down costs.
The necessary hardware was already implemented during design, and as such only the complex software needed for it is needed.
The approach to design it will be triple: building the base of the software; simulations; physical trials with the re-entering stages after the missions are completed.
This way, hopes are to be both efficient and fast in developing proper reusability.
SPECS=
Little Bear: Payload (max)=25'000 kg to LEO; | Cost per launch=120 millions NC$ (ridesharing allows to pay only a fraction proportional with the bought payload mass);
Heavy Bear: Payload (max)=100'000 kg to LEO; | Cost per launch=250 millions NC$ (ridesharing allows to pay only a fraction proportional with the bought payload mass);

Third (since you posted while I was writing this):
Again, you need to do RP's to develop the satellites and include (at least a rough description) of what their capabilities are. This is required regardless of whether they are built by you or various companies within your nation. Again, you need to launch the rocket and include those details. You also need to build new rockets between each launch.NCR wrote: ↑Sat Apr 15, 2023 11:12 am The first commercial launches depart from the spaceports carrying many, many satellites.
SANC too puts new sats into orbit, with purely scientific payloads, at various altitudes orbiting around the Earth.
SANC is now developing GUMS, a new constellation intended for GEO civilian and military purposes, and 3 new scientific satellites:
the first one intended to orbit and study the moon; the second one will be a powerful telescope in Lagrange Point 2; the third one will have a close sun orbit, to study it and the solar system as a whole.
Simultaneously, SANC continues working towards implementing reusability.
Aided by simulations, a new software to manage the re-entry and landing is implemented; while thanks to it the rockets now manage to arrive close to the specially-built re-entry pads, they still crash down without managing to land.
Those trials are made without wasting money since, after a LB carries its payload into the right orbit, the rocket's mission is finished; thus instead of a simple destructive re-entry a reusable landing attempt made.
As such, each launch brings SANC closer to implement viable solutions to the reusability problem.
Lastly, both CaliSTARS and MAGIC are now fully deployed, and reach full operability.
Sending satellites to the moon and/or sun orbit are going to be more expensive, take more time, and require more work overall. It is also not very feasible to launch them all as part of one launch, due to their relatively different required orbits.
Please provide details of CaliSTARS and MAGIC. But, as mentioned, first you're going to have to do the RP to actually develop the satellites.
