On September 1st, 2016, SpaceX’s Falcon 9 rocket suffered a catastrophic anomaly throughout a static hearth check, inflicting an explosion that fully destroyed the car, the launch pad, and Spacecom’s $200M Amos-6 satellite tv for pc. This finally triggered a months-long investigation into what CEO Elon Musk described as “probably the most troublesome and complicated failure [SpaceX has] had in 14 years.”

Greater than two years and 41 profitable consecutive launches later, SpaceX and Israeli satellite tv for pc operator Spacecom are reportedly aiming to launch Amos-6’s alternative – Amos-17 – as early as the top of Might, round three months from now.

Practically two and a half years distant, the reverberations of SpaceX’s Amos-6 Falcon 9 failure proceed to reverberate loudly. Apart from demanding modifications to the operational procedures used to launch Falcon 9 and forcing an in depth vital evaluation of design, manufacturing, and qualification strategies, SpaceX has spent numerous assets pursuing an in depth redesign of the element pointed at as the first supply of the explosion that destroyed Falcon 9. Generally known as carbon-overwrapped strain vessels (COPVs), SpaceX makes use of the bottles to retailer extraordinarily high-pressure helium (5000+ psi, 340+ bar) to pressurize Falcon 9’s RP-1 and oxygen tanks, in addition to nitrogen to energy its cold-gas maneuvering thrusters.

In accordance with a failure evaluation carried out by SpaceX with NASA, the USAF, the NTSB, and the FAA, it was concluded that the trigger could possibly be traced again to a posh sequence of occasions centered round these helium COPVs. Meant to be the primary mission to make the most of subcooled propellant and oxidizer, the intense chilly within the higher stage LOx tank triggered stable oxygen to type on the skin of the COPVs positioned inside it. Whereas complicated, the gist was that liquid (and maybe stable) oxygen may have fashioned across the outdoors of the COPV, probably discovering its method in between the carbon fiber wrappings, making a buckle within the fibers, and finally inflicting fibers to interrupt. Close to the top of this course of, these breaking fibers may have created a spark or breached the helium tank, instantaneously overpressurizing the higher stage and inflicting an explosion.

NASA’s Aerospace Security Advisory Panel (ASAP) and NASA itself have aired issues about these COPVs since 2016, triggering an awfully complete program of testing, characterization, and redesign of the COPVs SpaceX makes use of. They’ve now efficiently flown on Three-Four Falcon 9 launches below the identical expedited propellant loading circumstances that an equivalent rocket will bear in preparation for Crew Dragon launches. CEO Elon Musk spent a number of minutes discussing the redesigned COPVs in a Might 2018 press convention and didn’t mince phrases when he described them as “by far probably the most superior strain vessel[s] ever developed by humanity.”

“The quantity of testing and analysis that’s gone into COPV security is gigantic. That is by far probably the most superior strain vessel ever developed by humanity. It’s nuts. And I’ve personally gone over the check design, I’ve misplaced depend what number of occasions. However the high engineering minds at SpaceX have agonized over this. We’ve examined the residing daylights out of it. We’ve been in deep, deep discussions with NASA about this. And I believe we’re in an excellent state of affairs.” – SpaceX CEO Elon Musk, Might 2018

NASA and ASAP issues have since been alleviated, culminating on February 22nd with an official announcement that NASA was prepared for SpaceX to conduct the primary uncrewed launch of its Crew Dragon spacecraft on March 2nd. It’s thus nearly poetic that buyer Spacecom selected the identical week to announce a goal date for the Falcon 9 launch of a satellite tv for pc constructed to exchange the destroyed Amos-6, referred to as Amos-17. Quickly after the Amos-6 catastrophe, Spacecom settled on a free SpaceX launch contract for a future satellite tv for pc as a substitute of an instantaneous $50M payout. Procured for round $160M, SpaceX is reportedly focusing on the launch of the Boeing-built satellite tv for pc through the week of Might 27th, doubtless from Launch Complicated 40 (LC-40) – the identical pad that suffered intensive injury through the September 2016 anomaly.

Since Amos-6, SpaceX’s report of reliability has been successfully spotless and now stands at a powerful 41 consecutive profitable launches, together with Falcon Heavy’s February 2018 debut. Apart from the sheer quantity of launches SpaceX carried out in a bit over two years, the corporate has pushed full velocity forward in direction of its purpose of routinely reusing Falcon 9 boosters. Lower than 24 months after the primary business reuse, SpaceX has landed Falcon 9 boosters 34 occasions and reused them 20 occasions, numbers which are solely more likely to develop in 2019.

Set to happen shortly after the deliberate launch debuts of Crew Dragon and Falcon Heavy (commercially), SpaceX will hopefully be capable to place Amos-17 in a wholesome orbit and thus successfully retire the Amos-6 saga earlier than the second half of 2019.
