Ascension Mk2 Flight 2 Analysis

Although the first orbital mission was eventually deemed a success for the payload, the Ascension Mk2 failed in its attempt to place the satellite it carried into a stable orbit. This brought the Ascension team back to the drawing board to improve the Viklun upper stage and make it more capable of maintaining attitude with its Reaction Control System cold gas thrusters. In the months since the first mission additional design work was also carried out for the next payload, dubbed Kerbin II and meant to test out technologies that would be used in the first line of communication satellites we are hoping to deploy in 2021. Once the Viklun stage improvements and payload design were finalized the rocket was assembled without issue in the VAB but the day before launch a problem occurred with installing the Radioisotope Thermal-electric Generator. The RTG was installed late in the launch preparation because the heat it outputs would compromise the fairings if left too long without thermal control, such as that provided by the crew access tower when the rocket is on the pad. Thankfully the problem was easy to overcome and the mission was only delayed to the following week.

The Flight

With no issues popping up during pre-flight the Mk2’s K2-X main engine lit up on time at T-3s under command of the AFCS, throttled at 10% power to check for good ignition. At T-0 after chamber pressures were confirmed to be nominal the 4 solid rocket boosters were ignited and their hold down bolts blown away to allow the rocket to begin its ascent with a combined force of 191kN to produce just over 1.6Gs acceleration. Immediately after launch all four of the rocket’s fins actuated to roll the rocket from 45° to 60° heading over about 6s before beginning to pitch over downrange. At the time pitch-over began the two horizontal fins nullified their ability to react to roll inputs so later in the flight at supersonic speeds control flutter would be kept to a minimum to reduce vibrations on the payload. By L+10s the SRBs had begun to taper off their thrust and the main engine throttle started to increase in order to maintain a TWR of 1.5.

Progeny Mk7-B Flight 2 Analysis

Hot on the heels of the first launch, the second mission was set to rectify several issues that ended up leading to a mission failure. Although the modifications needed for the rocket were made in time for an on-schedule launch the weather had other plans and forced a one day delay. Once the skies cleared up however all proceedings up to the terminal count were carried out with no additional issues.

The Flight

With the service boom swung away and the rocket on internal power and radio-frequency comms, final preparations for launch were carried out mainly by the AFCS, now in control of the rocket. 5s before booster ignition the support arms holding the rocket steady against any sudden wind gusts were retracted to clear the way for ascent and at T-0 the 0.625m dual-segment SRB lit off to push the rocket off the engine support at 13:30:00.04 local time to begin its ascent.

With an initial TWR of 3 the rocket quickly gained enough speed in the first seconds for the guidance fins to have the authority to begin pitching the rocket downrange, heading the direction it was already facing – direct east. However instead the rocket went into a slight roll and actually ended up briefly pointing back west before correcting with another roll back towards 90° however upon reaching that head spun around again and continued to have trouble pointing itself in the proper direction to the consternation of controllers.

4 Years On – How IRL Will Impact KSA’s Future

Hello everyone, this is going to be an entirely out-of-character annual update because I want to be candid about how this project could be affected by in-real-life events moving forward given my current circumstances.

The KSA is becoming a “mature” agency now and that helps because it doesn’t tweet or generate content nearly as much on a daily basis as it used to back in the earlier years, however at the same time the complexity of the operations has also increased. The pandemic these past few months and me being unable to do my “real job” coaching gymnastics and thus spending nearly all my time at home has also brought about a startling realization: this whole project is taking up a lot more time nowadays than it used to. In earlier years I would have at least 2-3 weeks of lead time, sometimes as much as 2-3 months and now I’m struggling to keep ahead by just a few days.

There is another consideration however – the whole pandemic situation has also brought me closer to friends online since regular in-person gatherings aren’t really a thing anymore lately. Ironically this has eaten up time as well because it’s easier to get together online to play games than it is to coordinate IRL meetups. So before Covid I was spending less time hanging with friends but getting more from the in-person interaction so I felt less compelled to connect to them online often, freeing up more time for me to work on KSA.

Now, if I free up more time from gaming with my friends online that will help me stay ahead when lead time grows short but another upcoming problem will be when financial assistance for unemployment related to Covid dries up over the next few months. If I return to the gym to coach or search out some other employment opportunity because I need the money to sustain myself then that is once again less time I have to spend on this project.

If time becomes an issue, as I have said before I will be forced to scale back the timeline and scope of this project in order to allow it to continue. Updates will become fewer, background story elements will fade away, crew will develop less character and time between launches will be extended so that I have more time to prepare.

A final consideration for how much time I have to work on KSA activities is contributions from Patreon. Obviously if I can make enough money through here that I don’t have to spend as much time coaching or traveling away to fireworks shows then that is more time I can spend on this project instead. Currently I’m making just enough to cover the monthly $10 payment I make to prolific KSP mod author LinuxGuruGamer, who in keeping various mods alive also helps keep the KSA project moving forward with new KSP versions.

While I of course hope my personal situation and the pandemic situation stabilizes in the near future, I also doubt it’s going to happen – especially considering this upcoming U.S. election. I remain committed however to not voluntarily giving up the project. I take a lot of enjoyment seeing people react to what the KSA is doing and I thank everyone who has reached out to me over the years with comments and suggestions or even attempted to take part in the role play. It does mean a lot.

I’m really looking forward to making it back to orbit over this coming year and continuing on this journey with you all. Thanks for following along and please don’t forget to help spread the word about the KSA’s existence!

Drew Kerman,
Founder, Operations Director

Ascension Mk1 Flight 14 Analysis

Specialist Bob has had quite the long journey to get up into space. He was supposed to be the first to take the trip however the Monolith had other plans for our initial orbital attempt, which can be read about in more detail here. Nearly one year later his rotation finally came back around after first Bill then Val then Jeb all took turns flying up above the atmosphere. Always the one on the crew list with the most nerves, having 3 other kerbals return safely from space helped to put him at ease, although at the same time he couldn’t help but wonder if that meant he would be the one to not come back alive. Despite his anxiety, Bob got straight on board the rocket on launch day and retained his composure throughout the mission, despite the problems that were had.

The Flight

With no issues in the countdown, the ignition sequence began at T-6s to fire up the main engine and check chamber pressures as it throttled to launch thrust of 1.2 TWR. Clamp release was approved as the AFCS confirmed launch thrust and the rocket began its ascent, holding throttle steady until it had climbed over the towers. The rocket began to roll from 45° to launch heading of 54° but at L+6s the guidance computer decided that it was also supposed to be holding a 45° pitch angle and kicked the rocket hard over while still less than 500 meters over the ground. Needless to say this caused quite the commotion in launch control!

Progeny Mk7-B Flight 1 Analysis

Originally announced back in late 2019, the Mk7-B was meant to fly earlier this year however the bankruptcy of Umbra Space Industries and the following litigation led to the suspension of Progeny launches that lasted several months on top of the self-imposed general launch suspension earlier in the year. Finally, nearly a year after the last Progeny Mk7-A flight the Mk7-B conducted its first mission.

Leading up to the launch, the rocket was carefully checked out after having sat around for months since finishing assembly earlier in the year. Rollout to the launch pad was initially delayed due to mechanical problems with the carry vehicle and once out on the pad despite a good wet dress rehearsal additional delays were required thanks to some launch system upgrades that were made during the downtime between this and the previous unkerbed launch.

Two days after the new launch date operations were finally allowed to proceed in preparing the rocket for lift off. Pre-launch protocols went smoothly and weather was cooperative throughout.

The Flight

At L-2 minutes the terminal count procedures began with the AFCS taking command of the rocket as the service tower swung away to leave the spacecraft on internal power and radio comms. Leading up to the final T-30s polls battery drain rates were monitored and signal checks undertaken. With all systems GO, the rocket proceeded with final launch procedures and the support legs keeping it stable against any sudden wind gusts were retracted 5s prior to T-0.
