What did you do in KSP1 today?

Trying to recover the first stage of a Ferry Rocket:

Would anyone happen to know an alternative?

I can see two immediate possibilities -- delay ignition of the Landertrons a fraction, so they stop the stage closer to the sea surface (ideally, in the range between +2 and -2 m), or install additional conventional parachutes (large, and in large numbers) with a low opening altitude, to bring the descent velocity down to ~5 m/s.

I see difficulty in timing Landertron operation closely enough to get an acceptable impact velocity (a 5 m drop will give ~10 m/s, which is enough to destroy a lot of hardware), and even if you have an event timer to cut the 160 t of steel parachutes when the conventional parachutes deploy, the remaining 440 t is going to require a ridiculous crop of parachutes.

Could you install a sacrificial part, such as an inflatable heat shield, to take up the sea surface impact after your Landertron operation?

What did I do in KSP? Tried to get into KSP.

I'm finally updating to 1.3.1 along with re-installing my mods... and of course I'm getting crashes to desktop.

I posted a question in the help section. Hopefully someone here can assist me as well?

I made some tests for my first Jool mission. I put the transfer stage with the main ship in orbit using the cheats, and i made a Homman transfer to Jool, a mid-course maneuver to get a Tylo encounter, and a correction maneuver to use the Tylo encounter to put me in orbit of Jool. The maneuver was a sucess, i passed very close to Tylo (13 Km) and very fast (5.5 Km/s), but without problems. I entered in orbit of Jool, went to the Tracking Station, and i warped until a another Tylo encounter appear. But i warped too fast, and i don't knew that the encounter would put me in a escape trajectory of Jool. When i see, it was too late. So i lost the ship. But the mission was a sucess to go to Jool. Now i just need a lifter to put the transfer stage with the main ship in orbit. Anybody here have a lifter that put about 30 tons to LKO?

I learned some time ago that a Twin Boar with an additional orange tank has plenty of thrust and dV to put 15 t (plus a smidgen) into LKO with a single stage.  Put two of those together, and the result ought to lift 30 t without difficulty (as long as you don't add too much mass joining the two boosters together side by side -- just sticking them together ought to do).  In fact, use three of these, just stuck together, adapters and nose cones on the outer two and suitable mounting hardware on the middle one; then you'll get your 30 t into orbit with significant reserve.  No reason to overthink things or fool with trying to adapt 2-to-1 (and have the adapter cut into your 30 t transfer/payload stage mass).

Today, I finished bringing Val, Bob, and Adeny's clone back from their aborted Munar landing attempt.

When Val had the apoapsis down to around 300 km (after a total of five aerobraking passes between 56.9 km and 57.6 km periapsis), she reentered at aerobraking altitude, but pointed retrograde and burned the remaining Lf/O to reduce final reentry velocity (the fuel remaining, with none burned since Munar escape, amounted to appr. 400 m/s dV, or almost exactly half what would have been needed to brake to landing and return to Munar orbit, after accounting for what was burned recovering from the suborbital landing trajectory).  That burn only partially recharged the vessel's (nearly depleted) batteries, but the monopropellant tanks were nearly full, so Val used RCS pretty freely to manage angle of attack through the hotter part of descent.

In the end, final descent was over highlands, so Val opted to deploy the parachutes even with landing gear down, rather than risk rough ground causing a crash.  Final descent under parachute, with slight cushioning from RCS, gave a fairly gentle impact of 4.9 m/s.

Another 400 units of Lf/O would have given barely enough dV to accomplish the landing and return with this vessel, and suggestions for drop tanks, a further stretch, and other less sensible plans were flying before Val had even dropped below orbital velocity.  In addition to Mission Planning, R&D announced they were accepting recommendations for immediate future research.

Today the Duna-Phoenix did its intercept burn. The Phoenix lander is mounted on the transfer vehicle Apollo style (backwards). Having been busy managing other missions, when I came back to the Phoenix the control was active on the lander (not on the transfer vehicle)... 2 minutes into the intercept burn I realized something wasn't right - I was burning retrograde. Lucky for me I had plenty of fuel to spare.

I humbly accept the Dummy Of The Day award.

So, I have built a lifter stage for my Duna and Ike probes. Turns out, it's an SSTO, not even close of running out of fuel by the time I'm in orbit.

Should I put a probe core on in and try to land it back at the KSC? If yes, how do I consistantly get there?

consistancy requires either trial and error , quicksaving, tca or mechjeb. prayer results in fireballs. but this might help

Well I don't quicksaves, or use TCA or MechJeb... but trial and error kinda goes without saying. I find these quite useful...

Today I went to the Moon Rover and performed a Surface Exploration Mission:

Donbro landed 18km away from the Rover. 

Then the Rover drove to the Lander in order to pick him up.

 

 

Max. speed: 50m/s

180 km/h, you've build a german autobahn on the moon? :D

Hahahaaha yeah :D:D. But to be honest, such a speed is quite dangerous especially at the Moon ^^. When I drove down a hill and tried to steer the Rover, it did around six somersaults before

Donbro flew out of it and both hit the surface with more than 35m/s. Luckily he and the Rover survived. This happened around 4 times :rolleyes:

Now I want to build a rover and just drive endlessly on the Mun(or Minmus):)

Not much to show for, but I've been tweaking my RSS launchers to try to get greater efficiency out of 'em.  Also trying to come up with a naming scheme that tells me what it does without having to load the subassembly.  But more than that, I've been trying to make a whole new line of launchers that are cheaper than the previous generation.

So far, it's been successful, in that my 100ton launcher now costs nearly 1,000,000 kerbucks less per launch.  This will allow much more frequent launches, and a greater rate of science income.

As for contracts, I expanded Space Station: Earth in LEO:

Also put a relay sat into geostationary orbit for a contract, and used the opportunity to test out an Argon-powered Ion engine:

Made a launch during some very interesting weather patterns:

After that, I put a small unmanned rover on the Moon.  Not particularly fast, it tops out at about 10m/s on flat ground:

And lastly landed a small outpost on the Moon, with Life Support for at least a year:

Added a few more mods to get myself closer to an RO-like install, including FAR and Real Scale Boosters.

I totally krakened the entire install after Hyperediting a ship to a very large orbit around the sun. (I think it was over 1E100 m)

Now no rockets can be launched and the space center is glitchy in all saves.

I had to delete the install...

Great job, Realism Cataclysm! You lasted a whole day!

Well, who would put a probe into a sun orbit 1 googol in radius anyway?
