Progeny Mk7-B Flight 4

With a final chance at mission success, objectives are changed with the addition of an actual payload to test a prototype Luciole smallsat probe and only recover the 1st stage booster, which is the same flown on the 1st flight from Aug!

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.

Low-Altitude Science Survey 63

Releasing two balloons over Sector KD-T for Tiberdyne Aerospace this mission will take advantage of the orbiting Kerbin II to stay in communication & thus require less support to be taken along

Progeny Mk7-B Flight 3

Looking for the third time to be the charm, changes are made to the early ascent to hopefully ensure mission success at last and while they seem to work ultimately we are forced to declare this yet another failure upon recovery

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.
