Progeny Mk6 Block II Flight 1 Analysis

Since it was first announced back in October of 2017 (then designated the Mk5) the Block II has never been called upon for a mission due to the Block I out-performing all expectations and delivering payloads to the region of space above 250km that the Block II was originally designed for. After months of using Block I rockets to explore the hazardous radiation region above the planet, the need for higher flights has finally allowed the Block II the chance to prove its worth. The first mission was launched last week and once again the Progenitor team was blown away by the results.

The Flight

With no issues leading up to launch, the rocket lit off all 5 of its first stage solid rocket engines and left the launch base in a pillar of fire at 12:03:00.04 local time. This produced an initial combined force of 6.2Gs which, coupled with the added weight near the nose of extra batteries for the longer flight, prevented the greater length of the rocket compared to the Block I from creating too much drag at the nose and flip over to the west. In fact, the rocket immediately began to pitch downwards upon leaving the launch base, dropping from 85° launch position to 80° in the first 5 seconds. By this point the radial boosters had done their job aiding the center core booster in overcoming the additional 129kg of fuel and parts (not to mention the weight of the boosters themselves) added to the rocket design in the Block II. They separated, however two of the boosters caught the fins of the lower stage as the rocket began to spin up. Thankfully this did not have a hugely adverse effect on the ascent.

New Space Radiation Revelations

The first flight of the Progeny Mk6 Block II gave us some new insight into the region of hazardous radiation that has been found to hover above our planet. If you need a refresher, this article we posted earlier this year will get you up to speed. With the Block II finally being able to pass through and confirm that there is an upper boundary, it brings new context to the data gathered in the past and has brought us closer to understanding exactly what type of structure exists around Kerbin.

Ascension Mk1 Block I Flight 1 Analysis

After many months of development the time finally came to launch our first orbital-capable rocket into the sky and see if we could place it into a decaying orbit around the planet. The mission was designed this way because the rocket engine could not be re-lit after shutdown to de-orbit and no steering capabilities existed for outside the atmosphere to point the rocket in the right direction anyways. While achieving orbit was the main goal, the mission also had to act as a proving ground for several important aspects of the design, such as guidance and ascent tolerances. While the mission saw success in these areas, overall it was a failure due to the rocket not being able to achieve an orbit during flight.

The Flight

Because this was the first launch, several issues preceded our ability to reach the point of lift-off including problems with the new ground service equipment that was constructed to support the launch operations and the rocket carry vehicle in positioning the rocket upright for mounting. Overcoming these problems, the day of the launch also saw an additional issue when the first attempt at lift-off threw an abort that caused the main engine to shut down shortly after ignition due to low engine chamber pressure. Broadening the tolerances of the flight computer and running through to T-0 a second time allowed the engine to achieve the thrust levels required for a TWR of 1.2, which then cleared the AFCS to release the rocket from its engine support collar and begin its ascent.
