  1. For a stock solution you could place a test-planning probe into a solar orbit, just ahead (or behind) kerbin and with the same orbital period (426d 0h 32m 24.6s (or circular with AP & PE of 13,599,840,256m)), once in position you can use the probe's manoeuvre node to test for and see when transfers are coming up!

  2. @XB-70A those are amazing pics!! I'm feeling pretty jealous or your launch-side seats about now! :)


    *reaches for tin-foil hat*  but did we just watch the launch of a bunch of experimental hunter-killer satellites?

    While viewing the launch broadcast we get to hear about some of the experimental payloads that will be tested:

    • armour 
    • local area sensing for on-orbit anomaly detection
    • mycroft sub-satellite which is highly manoeuvrable + lots of dV 
    • advanced guidance navigation & control for use in geosynchronous orbit

    It seems that these tests will lead to craft that can dodge incoming kinetic attacks, and perhaps become kinetic weapons themselves?

  3. The fourth (and cheapest) option is to combine multiple antenna on the same craft!

    Having 4x communotron-16 should let you operate anywhere in Kerbin's SOI with the tier 1 tracking station.

    My rough rule-of-thumb is: 4x antenna = 2x range; 8x antenna = 3x range; however the thread below might be more helpful :)


  4. i wonder what would happen to an actual grapefruit in space, and if you could transport them (say to mars) through the vacuum of space without need for life support? would the fruit freeze, or turn to dust, or maybe gain new powers from solar radiation? how long would they last? and what would they taste like? :)

  5. The zig-zag looks more like a pair of trenches with the dirt stacked beside them, leading from both launch pads back to the blockhouse. Perhaps these trenches contain services for fuel, water, power, launch control, sensor data, etc..  

    Probably they are zig-zaged to limit damage if an exploding rocket lands on it!

    I downloaded the BS-168, it has some part that is not AP+ or Tweakscale. I thik it's the tail part, size two tail or something. I sympathize, most of my planes accidentally had a KAX part in them.

    All parts are Airplane Plus or stock, so I'm not sure why your install is struggling to load parts?

    But perhaps it is a fortuitous event, as actually I would prefer someone (anyone) else to review my craft! Many of your reviews and posts seem overly negative, combative, disparaging of peoples efforts, and biased towards promoting your own entries. Thoroughly un-kerbal in my opinion. 


  7. Flight Fourteen 

    Resting on the pad, Jeb’s finger hovered over the go button for 290 tonnes of liquid fuelled bang! With five Kerbals aboard (including Theolo, a new scientist) things would be more fun than Jeb’s solo flight to Duna. 


    The side boosters separated perfectly, but with no possibility of recovery...


    Jeb made sure to leave the fairing and core booster on a suborbital trajectory; “combatting Kessler” he said, however mission control suspected Jeb just didn’t want any more debris beating him to world firsts.


    Bob collected some science for perusal en route, while final adjustments were made for transfer to Eve.


    Transfer burn underway! Aside from one mid-course correction the journey to Eve was uneventful, with the scientists toiling away in their lab while the other crew bounced about the hitchhiker module.


    On final approach to Eve  the solar arrays were retracted in preparation for aero-capture. Everyone was nervous for this manoeuvre, having never encountered an atmosphere this thick and this fast before!


    Heat tolerances were pushed to the very limit as the craft dipped down to 80km altitude and captured into a long elliptical orbit. Over the next weeks several more passes were made (although none so deep) for science and to arrange an eventual intercept with Gilly.


    The mystery cargo was deployed into a parking orbit of Eve in preparation for an eventual landing.


    The amount of fuel required to circularise around Gilly was unexpectedly high! Mission planners had anticipated some gravity assistance, however Gilly didn’t seem to have any... Concerns that the crew might become stranded were growing, and back at mission control the beard-scratching had commenced as several solutions were tested on paper... Forging ahead regardless of danger, the crew detached the landing vessel and headed for the surface.


    Landing easily (if slowly) it was noted that a much smaller landing craft might have been used. All three biomes were visited, and the new guy earned his stripes when he was the first to notice the lander tipping and sliding away during a photo shoot!


    Val handled the ascent (having beaten Jeb in a foot-race to the driver’s seat) and completed one of the slowest rendezvous and docking in recorded history. With the new ship arrangement extra care would need to be taken at each burn to ensure the engines were pointing in the correct direction.


    While mission planners were determining how bad the fuel situation was, the main ship was left to orbit Gilly and attention was refocused to the mystery cargo. Control of the cargo was limited due to it's short range comms, but after Gilly completed an orbit the main ship’s relay antennas were back in range, and entry into Eve’s atmosphere was able to be set.


    Things were looking hot, but the extra flames were needed to ensure the cargo got to the surface while still within radio range.


    Like a butterfly, the baby rover emerges from it's fairing cocoon, tasting sunlight for the first time as it floats gently to the surface.


    The little rover looks happy on the surface, despite the crushing pressure and scorching temperature! Science was transmitted from two biomes.


    Back on the main craft calculations were being made to return home, but more and more it seemed that the dV needed (up to 1,930dV from Eve orbit according to the dV map on the wall at mission control) exceeded the amount available.  Possible options were devised to increase the dV of the craft: 

    • option A - burn the monopropellant, then the LFO for 1,197dV total
    • option B - burn the LFO, jettison the lab and empty tanks, then burn the monopropellant for 1,388dV total (but then have no power generation)
    • option C - ditch the heatshield then do "option B" for 1,481dV total (but then risk a dangerous reentry at Kerbin, and also have no power generation)

    Things were looking grim, as none of the options would come close to working, until a flight planner devised a bold stratagem for a minimal dV return using the following steps:

    • Escape from Gilly and park in an even higher circular orbit (45,000km) for 130dV
    • Wait for the Kerbin transfer window to open
    • From the high orbit, lower the periapsis to 100km for 330dV using use two burns over two orbits, ensuring the new periapsis aligns with both the ejection angle (location) and transfer window (time)
    • Transfer burn now only requires 120dV to escape Eve! Huzzah! 

    So for the bargain price of 580dV everyone would be heading home, and Jeb would not have to get out and push this time. So long Eve! 


    By shear dumb luck the Kerbin intercept aligned with the descending node, so no fuel was required for a plane change. This bonus fuel was used to place the lab with it's relays into a parking orbit of Kerbin, while the crew parachuted safely to the surface in the lander.

  8. Does aero-capturing count as diving into the atmosphere? If so, then I may have an entry for the challenge :) 

    challenge checklist:

    • make a manned craft & get to Eve - done.
    • dive into the atmosphere - done, but only made it down to 80,000m
    • cargo dropped - yes!
    • return to Kerbin - completed

  9. @neistridlar thanks for the balanced review! I'm glad you liked the low-slung fuel tanks, and the sturdy construction, and right about now I'm slapping my forehead wondering "why did I never mirror the stair-cart?!" You have opened my eyes sir! :)

    I may take your advice too, and design any future shared craft with "no trim required" and "flight by SAS" in mind, even though I don't use it myself (usually my flights are undertaken by scientists) it seems to be the popular way to fly.

  10. Flight Thirteen

    The milestones in the Kerbin system were nearly depleted, so it was time to go further afield... to Duna! Bill and Jeb had been tinkering with the troublesome first stage, trying all kinds of solutions and eventually settling on a simple asparagus arrangement with two side LFO boosters also supplying a central core. Some SRB were also added to give some more kick off of the launch pad. Bob helped out too by gluing on some extra mystery goo pods.


    After many months in mission control with a protractor held to the screen, the day of the big launch finally arrived. The improved first stage delivering Jeb practically all the way to orbit, leaving the second stage primed to burn for Duna.


    Once underway, Jeb was a little saddened to discover he was no the first to orbit the sun: turns out a piece of debris from an earlier mission beat him to the punch! Science was collected and transmitted back to Kerbin until the radio was out of range, and then Jeb was all alone... except for a red dot getting bigger in the window.

    Duna's thin atmosphere was used to gently aerocapture into an orbit, and to intercept Ike without burning any fuel. Some cheeky science was also gathered while slowing the craft in Duna's upper atmosphere, with Jeb even stepping out into the flames momentarily to collect an EVA report!


    Science was collected in high space and low for both Duna and Ike, and then the lander was used for.. well... landing!


    Touchdown was a breeze, Jeb later said that it was "like landing on the moon, only easier" Two biomes were visited via "hopping" before all the science tests were consumed and it was time to return to space. Heading home to Kerbin involved a low parking orbit around Duna and more time spent in mission control with a protractor, eventually making it back 2 years 304 days after launch with fuel to spare.

  11. Flight Twelve

    For this mission Val decided to head to Minmus, and show Jeb how a landing should be done! After the debacle of the last flight the lander and transfer stage were redesigned to save weight, and at Jebs insistence a liquid fuelled first stage was developed, relegating SRB to the role of booster only.


    After launching it was discovered that the first stage was still lacking in performance, burning out early. Fortunately the improved transfer stage had more than enough dV to circularise and make it to Minmus


    Flags were planted, and two biomes were visited before Val returned home with a cheeky smile and a comfortable fuel reserve.

  12. @Clipperride i'm glad you enjoyed the plane! If I had been quicker I would have put in up on kerbalX for you, actually... here it is anyway, for science! :)

    It is a little sluggish to turn, but steady as a rock when flying at 4x time acceleration. Cruising altitude is around 10km @ 310m/s 

    I find the secret to building sturdy craft is to minimise the branching of parts from the heaviest part (no more than 2 or 3 branches), and maybe include a sneaky strut! 

  13. Flight Eleven

    From the launchpad, tucked away under an upside-down fairing, Jeb grumbled that SRB's were a bad idea. Sure they were cheap and had lots of punch, but they lacked in dV... Yet the accountants had insisted, saying the funds were needed elsewhere for facility upgrades.


    As the Mun happened to be rising during launch, the circularisation burn also became the transfer burn... almost... as the second stage burned out early and the lander was required to fire it's engine.


    Touchdown was successful, despite overshooting the intended landing site by nearly 10km. Jeb elected to preserve ship fuel by jetpacking to the target location for the flag planting ceremony, but the distance was too far and so much eva fuel was consumed that Jeb would be forced to walk back to lander.


    And so a 4 minute jetpack became a 3 hour walk!! I'm not ashamed to admit that I rigged up a rubber band and an eraser to hold down the "W" key while I went and did some household chores (vacuuming, fold the laundry, restock some herb jars). Eventually Jeb made it, and swore  never to do this again!


    After taking off from and escaping the Mun the inevitable happened: the ship ran out of fuel. Refusing to be beaten and with the ship's periapsis firmly stuck 800km above where it needed to be, Jeb did what any determined Kerbal would do: he got out and pushed it home! :D

  14. Flight Ten

    Val was determined to show off her local knowledge by flying a prototype plane to various mystery locations.

    The nearby abandoned airfield was quickly toured before turning westwards. After crossing the ocean and a desert, grand ancient structures are revealed.


    Next, some mysterious buildings are located at the source of a radio relay... could this strange facility be stealing science data?


    Finally, after heading north to the limits of the craft's fuel range the faintest speck of an unusual craft is spotted against the snowy vista (images of the craft have been classified!)

  15. @TheFlyingKerman is correct, visiting an easter egg counts as a milestone!


    we have discovered....

    • an abandoned island airfield on Kerbin (4,800 funds)
    • some desert pyramids on Kerbin (4,800 funds)
    • an abandoned space centre on Kerbin (4,800 funds)
    • a vessel of unknown origin on Kerbin (4,800 funds)
    • the memorial of a legendary kerbonaut on the Mun (16,640 funds)

    I'll soon post my today's missions where Val and Jeb visit some easter egg sites, once I manage to get everyone home safely that is!
