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.

#045: IP ComSat II Déjà Vu
The KSA has readied a third satellite for launch into polar orbit to complete the first interplanetary communications network around Kerbin. The first launch failed during ascent, the second launch was successful, and now the Agency hopes to add another good launch to their record. Once in place, the two IP ComSats will allow Mission Control to contact craft anywhere in the Kerbol system, staying both high above and below the orbital plane as much as possible to improve chances of connections.

#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.

#042: 2.5m Engine/Mk1-2 Recovery Trials
With the upgrades to the VAB complete, the KSA now has the ability to construct larger 2.5m craft in addition to any 1.25m rockets already under construction. Before they can launch their first 2.5m rocket, there are two new engines to test. The main lifter cluster is actually using the Bearcat engine that has been the lifter engine of choice for the KSA mostly since day one. However it has only before been clustered in pairs. A new orbital engine to replace the 1.25m RMA-3 workhorse is also in need of testing. Once the tests have proven successful, the teams can assemble a 2.5m test vehicle to put the new Mk1-2 capsule through an unkerbed orbital mission to ensure it can return safely.

#041: Automated Rover Test Drive #5
Although the previous drive was ultimately successful, engineers on the rover team were still not satisfied with the damage done to the rover and the inability of the software to properly acquire the next waypoint. Further refinement to the driving parameters and some refactoring of the guidance code gives them high hopes of a clean run from start to finish on this next drive out to the west shore desert. Once again, the rover will be completely on its own and assisted only from mission control at KSC.

#040: Automated Rover Test Drive #4
Previous drives of the rover focused on testing and refining the code the would allow the rover to navigate itself over difficult and unknown terrain. The team is now at the point where they feel confident enough in the rover’s abilities to not only go out and drive itself around without a pace vehicle for backup, but also while carrying the full suite of instruments and equipment that will be loaded on it for its actual mission to Mun. Accidents now will not only endanger the rover, but the operability of several delicate science instruments.

#039: Automated Rover Test Drive #3
The previous test drive ended in disaster as the rover failed to control its speed as it backed down a steep slope it could not climb, tumbling and wrecking itself. While a new rover body was constructed, engineers used the time to work out what went wrong in the code and corrected the problem. This drive would take the rover straight out to the mountains to make sure the new code behaves as expected.

#038: IP ComSat I Ascent Failure
With the Duna I mission undergoing final construction this month for launch at the beginning of December, the KSA is using the time to put in place two new communications satellites around Kerbin that will provide links to any craft operating in interplanetary space. The R&D department recently rolled out their largest dish yet, capable of communicating as far as Eeloo. This was to be the first of two satellites orbiting high over Kerbin’s poles, and is also the first rocket to incorporate recoverable boosters.

#037: Automated Rover Test Drive #2
After successfully navigating 169.3km from KSC out to the west shore desert, the rover team got to work planning an even harder route back home that would test the rover’s ability to handle a slope it couldn’t navigate, as well as refactoring a large portion of the rover driver software to give the team more data to look at while the rover operated.
