Progeny Mk6 Block II Flight 2 Analysis

Ever since the Block I outperformed all expectations and flew into the region of space we expected to use the Block II to reach, this rocket hasn’t been able to find a good use in our launch lineup which is why this is only the second launch since it was first conceived back in late 2017. The mission however was well-suited to our most powerful rocket to date, which was to go as far out into space as possible to gather new radiation data and look for a second radiation belt. In addition to building on the previous radiation discoveries, an additional mission goal was to test new hibernation technology to extend the vessel’s battery life long enough to last a mission that could take several hours.

The Flight

The rocket had a clean launch, leaving the mounting base without impacting the support rail while firing on all 5 solid rocket motors for a total initial thrust output of 214kN, producing just over 6Gs of force to keep it pointed downrange as the nose began to lower and the fixed fin angles began to spin the rocket up. The main difference between the Block II and Block I are the 4 radial boosters that accelerate the larger and heavier Block II rocket up to speeds comparable to a Block I. They burn from 5-6 seconds before being discarded. During the first flight, the booster separation led to an impact with two of the large lower fins thanks to the decouplers throwing them away with enough force to remain lateral to the rocket. The solution was simply to let them drop away on their own by force of the rocket’s speed and spin. All four boosters made a clean separation although the rocket exhaust did scatter them and actually flung one back far enough to impact the Ascension service towers! Thankfully no major damage was done.

Progeny Mk6 Block II Flight 2 (Radiation Field Study 8)

We prevented the Block II from reaching its full potential last time but now we are ready to let it fly all the way and see just how far we can explore the space above for new regions of increased radiation

Scientists Report Radiation Belt(s?) Envelop Kerbin

The data gathered from Progeny rocket flights made over the past several months have allowed scientists to put forth strong theories on what kind of radiation environment exists up in space near the planet. It will take more missions, especially orbital ones, to prove these theories but observations strongly fit with the ideas being tested. The most conclusive evidence so far came from a mission launched last month, which had a Progeny Mk6 Block I fly over the night side of the planet. Before that, we have posted other reports on the missions sent up to gather data about the so-called hazardous radiation region, which you can start reading here if you need to recap.

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.
