The third and final ComSat to orbit Minmus was successfully launched into LKO, where it transferred without issue to Minmus and detached from its transfer stage in orbit around the moon, leaving it to drift until we re-activate it for use as an impactor. In order to slot the satellite into position between the two existing ones, an aggressive maneuver was plotted to send the craft whipping past Minmus as low as 15km, after which it would rise up to complete the constellation of communication satellites.

#054: Back In Bizness – ComSat Minmus I
After over a month of repairs required to get the launch pad back to operational status after being nearly destroyed by 2.5m rocket launches, the KSA is finally ready to really kick off 2015 operations. We are starting small, however, to ensure the pad repairs have been adequate. The ComSat Minmus I satellite will be the first to orbit the second moon of Kerbin and will be the start of another triple-constellation around the equator that will provide complete omni network coverage for future craft. We plan to make Minmus an important way station for future kerbed space flight so this investment in communications infrastructure will pay off down the road. This mission would also go on to uncover a serious flaw in our mission planning software that would affect another planned launch.

#055: Duna I (Part 2/2)
The planning, development, construction, launch and transfer burn of Duna I were covered back in Dispatch #48 and we now pick up the story from when the craft exited the Kerbin system. 71 days of transit later after a mid-course correction burn it was due to finally arrive at Duna, becoming the first space craft to travel to another planet.

#053: Kethane Refinement
For months now the R&D branch of the KSA has been working tirelessly to turn kethane, an abundant mineral found both here on Kerbin and in spectra on other bodies in the solar system, into rocket fuel. Not only would this greatly reduce our dependency on other sources of propellant, it would allow us to refuel in-situ, saving costs and weight on future missions to the surface of other planets and moons. The road was long but eventually scientists were able to deploy and test a drill and converter unit here on Kerbin.

#049: Automated RCS Maneuver Testing
The KSA has been aware for some time of a limitation with their remote operation system, which is capable of pointing the rocket and performing burns with an engine when not in contact with mission control (assuming these commands were programmed while contact was established). What it is *not* capable of is controlling the RCS system. Since most of our small probes rely solely on RCS to perform maneuvers, this has been a small problem for operations around Kerbin, and only becomes a larger one when conducting maneuvers on probes outside the system. The solution is finally at hand with some new software, but to test it the Agency needs to loft a probe up into LKO, after which it was planned to be de-orbited once the software is confirmed operational.

#048: Duna I (Part 1/2)
The first inkling that the KSA was planning an interplanetary mission came back in August of 2014. It took three months of planning and construction of the probe parts (including new solar panels, radar topography scanner, and science instruments) followed by two months of construction and testing for the rocket (including new SRBs, a new orbital engine and an entirely new 2.5m rocket system). The end result was the most advanced craft to date, which was needed to get its payload as far as Duna. Launched during a transfer window, the journey would still take several weeks. This dispatch covers the design, testing, construction, launch and TDI burn that sets the craft on its way towards interplanetary space.

#047: IP ComSat II Redeux
The Inter-Planetary Communication Satellite network has so far seen several setbacks, mainly the fact that both IP ComSats failed to achieve orbit on their first launches. In the case of the second launch failure, actual sabotage was alleged by some news agencies, although independent investigation by the KSA is underway and has so far turned up no conclusive evidence of tampering with the launch vehicle. The KSA only needs two satellites to complete this network, but the failure of this second attempt to put IP ComSat II into orbit could jeopardize the entire operation and place extra stress on the KSA to explain these issues to its investors. With all this in mind, Lead Engineer Simon and his team have worked diligently in the hopes of finally completing the IP ComSat network with this launch.

#046: Mk1-2 Capsule Return Test #2
The previous capsule return test was perfect right up to the point where chute deployment failed to return the capsule safely to the ground after re-entering the atmosphere. Engineers re-did the math and tweaked the chute timings to give the capsule enough altitude to slow for a safe landing. In addition, a new SRB design and solar panel array was available to be used with this launch to test their performance prior to their use on Duna I. The LES was retained throughout the mission to help document the spacecraft, which was especially useful during the early stages of re-entry before heat seared the lens.

#044: The Dawn of Interplanetary Comms
With the previously-failed launch of IP ComSat I, the second craft already under construction was used for its replacement. The purpose of these satellites is to achieve extremely elliptical polar orbits in order to spend the maximum amount of time above/below Kerbin for best possible line of sight to other planets in the Kerbol system. A dish capable of reaching as far as Eeloo is included on each satellite, as well as two smaller dishes to help connect craft traveling around the Kerbin system. In addition to placing IP ComSat in orbit, some existing hardware up in LKO was re-purposed to help create a more redundant communications network around Kerbin.

#043: Automated Rover Test Drive #6
After finishing up maintenance on the rover, which experienced some technical difficulties on the previous drive, the team once again unleashed Lupek out into the wilderness hoping for a clean drive from start to finish. They were also testing out a new feature of the driving software that would allow Lupek to retrace its route back to the start. As Lupek has already proven itself on long voyages, the team decided to only send it out as far as the grasslands and back.
