SpaceX to launch replacement satellite two years after fateful Falcon 9 failure

On September 1st, 2016, SpaceX’s Falcon 9 rocket suffered a catastrophic anomaly during a static fire test, causing an explosion that completely destroyed the vehicle, the launch pad, and Spacecom’s $200M Amos-6 satellite. This ultimately triggered a months-long investigation into what CEO Elon Musk described as “the most difficult and complex failure [SpaceX has] had in 14 years.”

More than two years and 41 successful consecutive launches later, SpaceX and Israeli satellite operator Spacecom are reportedly aiming to launch Amos-6’s replacement – Amos-17 – as early as the end of May, around three months from now.

Nearly two and a half years distant, the reverberations of SpaceX’s Amos-6 Falcon 9 failure continue to reverberate loudly. Aside from demanding changes to the operational procedures used to launch Falcon 9 and forcing an extensive critical analysis of design, production, and qualification methods, SpaceX has spent countless resources pursuing an extensive redesign of the component pointed at as the primary source of the explosion that destroyed Falcon 9. Known as composite overwrapped pressure vessels (COPVs), SpaceX uses the bottles to store extremely high-pressure helium (5000+ psi, 340+ bar) to pressurize Falcon 9’s RP-1 and oxygen tanks, as well as nitrogen to power its cold-gas maneuvering thrusters.

According to a failure analysis performed by SpaceX with NASA, the USAF, the NTSB, and the FAA, it was concluded that the cause could be traced back to a complex series of events centered around those helium COPVs. Meant to be the first mission to utilize subcooled propellant and oxidizer, the extreme cold in the upper stage LOx tank caused solid oxygen to form on the outside of the COPVs located inside it. While complex, the gist was that liquid (and perhaps solid) oxygen could have formed around the outside of the COPV, potentially finding its way in between the carbon fiber wrappings, creating a buckle in the fibers, and ultimately causing fibers to break. Near the end of this process, those breaking fibers could have created a spark or breached the helium tank, instantaneously overpressurizing the upper stage and causing an explosion.

NASA’s Aerospace Safety Advisory Panel (ASAP) and NASA itself have aired concerns about those COPVs since 2016, triggering an extraordinarily comprehensive program of testing, characterization, and redesign of the COPVs SpaceX uses. They have now successfully flown on 3-4 Falcon 9 launches under the same expedited propellant loading conditions that an identical rocket will undergo in preparation for Crew Dragon launches. CEO Elon Musk spent several minutes discussing the redesigned COPVs in a May 2018 press conference and did not mince words when he described them as “by far the most advanced pressure vessel[s] ever developed by humanity.”

“The amount of testing and research that’s gone into COPV safety is gigantic. This is by far the most advanced pressure vessel ever developed by humanity. It’s nuts. And I’ve personally gone over the test design, I’ve lost count how many times. But the top engineering minds at SpaceX have agonized over this. We’ve tested the living daylights out of it. We’ve been in deep, deep discussions with NASA about this. And I think we’re in a good situation.” – SpaceX CEO Elon Musk, May 2018

NASA and ASAP concerns have since been alleviated, culminating on February 22nd with an official announcement that NASA was ready for SpaceX to conduct the first uncrewed launch of its Crew Dragon spacecraft on March 2nd. It’s thus almost poetic that customer Spacecom chose the same week to announce a target date for the Falcon 9 launch of a satellite built to replace the destroyed Amos-6, known as Amos-17. Soon after the Amos-6 disaster, Spacecom settled on a free SpaceX launch contract for a future satellite instead of an immediate $50M payout. Procured for around $160M, SpaceX is reportedly targeting the launch of the Boeing-built satellite during the week of May 27th, likely from Launch Complex 40 (LC-40) – the same pad that suffered extensive damage during the September 2016 anomaly.

 

Since Amos-6, SpaceX’s record of reliability has been effectively spotless and now stands at an impressive 41 consecutive successful launches, including Falcon Heavy’s February 2018 debut. Aside from the sheer volume of launches SpaceX performed in a little over two years, the company has pushed full speed ahead towards its goal of routinely reusing Falcon 9 boosters. Less than 24 months after the first commercial reuse, SpaceX has landed Falcon 9 boosters 34 times and reused them 20 times, numbers that are only likely to grow in 2019.

Set to occur shortly after the planned launch debuts of Crew Dragon and Falcon Heavy (commercially), SpaceX will hopefully be able to place Amos-17 in a healthy orbit and thus effectively retire the Amos-6 saga before the second half of 2019.

Why SpaceX is finishing another space-internet system that isn’t Starlink

SpaceX launched three final O3b mPower satellites Sunday, finishing a lesser known SES satellite network.

Published

on

By

SpaceX had an 87 minute window opening at 2:49 p.m. Eastern on Sunday to fly a Falcon 9 out of Cape Canaveral carrying the final three satellites for SES’s O3b mPower constellation, a project that has taken more than a decade to finish since Boeing and SES first signed SpaceX on for the work.

Unlike the thousands of Starlink satellites SpaceX has stacked into orbit over the years, O3b mPower flies in a different neighborhood entirely. The three new satellites, tagged F11, F12 and F13, are headed for medium Earth orbit at roughly 5,000 miles up, more than ten times higher than Starlink’s shell around 340 miles but still a small fraction of the 22,000 miles where old school geostationary satellites sit. That middle position is the whole point, because a satellite that far out needs far fewer siblings to blanket the globe than a low orbit constellation does. Essentially, SES only needed 13 satellites total to build a network offering quick, steady service that used to require thousands of spacecraft.

With most people having heard plenty about Starlink and almost nothing about O3b mPower, SES and SpaceX already blend the two networks for some customers. Both SpaceX and SES sell satellite broadband, but they’re aimed at different buyers. Starlink is built for volume, direct to consumers, RVs, homes, small businesses, plus a growing aviation and maritime business. O3b mPower skips consumers entirely and sells enterprise grade connectivity to airlines, cruise lines, offshore energy operators, telecoms needing backhaul, and governments, priced and provisioned more like a dedicated circuit.

A 2023 partnership lets cruise ships combine Starlink’s speed with O3b mPower’s steady capacity depending on what a ship needs at a given moment. Sunday’s completed 13 satellite constellation effectively finishes the medium orbit half of that pairing, years after.

Sunday’s mission was already a something on SpaceX’s manifest well before O3b mPower entered the picture. This flight marked its 29th trip to orbit, a history that includes two crewed Axiom missions, the European Space Agency’s Euclid telescope and 22 separate Starlink batches. SpaceX has landed boosters on the droneship A Shortfall of Gravitas so often that Sunday’s touchdown attempt, if it went as planned, was set to be the 661st successful Falcon booster landing to date.

For a company that pushed the Starlink constellation past 11,000 satellites back in August, almost entirely through bulk launches from California, Sunday’s flight was a reminder that SpaceX’s schedule still has room for someone else’s satellites too. SES gets a finished network built for a narrower set of customers, and Falcon 9 gets one more line on an already long resume.

Tesla gives the Roadster an official “Go for launch” demonstration date

Tesla teased an October 1 Roadster reveal, reviving years of delayed SpaceX thruster hover promises.

Tesla teased an October 1 event date for its next generation Roadster, posting an image on X Saturday that shows the car lit up like it is sitting on a launch pad, with the date “10.01” stamped across the bottom and the caption “Go for launch.” A countdown clock on Tesla’s Roadster order page now points to the same date, which falls on a Thursday. The company has not said where the event will happen or whether it will be streamed at the moment. Stay with us @Teslarati for live updates.


Tesla has since sent formal invitations to reservation holders confirming the event will take place in Waco, Texas, about 90 minutes north of its Austin headquarters, based on a digital ticket shared on X by Sawyer Merritt. Tesla did not name the exact venue, though Waco sits close to SpaceX’s McGregor, Texas, rocket test site, previously reported as the planned location for a Roadster thruster demonstration. The invite sets the reveal for 8:30 p.m. Eastern on October 1, requires RSVPs by midnight on September 16, and limits entry to guests 21 and older. Invitations are non-transferable.

The tease follows nine years of a project defined by unimaginable specs along with slipped dates. Musk first showed the second generation Roadster in November 2017 as a surprise reveal at the end of the Tesla Semi event, promising a 0 to 60 mph time under two seconds, a top speed above 250 mph, 620 miles of range from a 200 kWh battery, and production starting in 2020. At last November’s shareholder meeting, Musk set an April 1 demo date and joked the choice gave him “deniability” if it slipped again, which it did, moving first to late April, then to “a month or so,” then to August.

Whatever Tesla shows on October 1 is expected to center on the SpaceX developed thruster package Musk has described since 2018. Internally code named A71, a nod to the Lockheed SR-71 Blackbird, the system reportedly uses cold gas thrusters fed by a composite overwrapped pressure vessel, the same tank design SpaceX uses on Falcon 9. Musk has said a thruster equipped Roadster could hit 60 mph in about 1.1 seconds under roughly 2.75 g of launch force, well past the 1.9 second figure quoted for the standard car. That version reportedly will not be street legal and has reportedly been discussed as a limited run sold through a track only program.

The standard Roadster is still expected to carry the original $200,000 base price and $250,000 Founders Series tier, both set when Tesla opened $50,000 and $250,000 reservations in 2017. Tesla VP of Vehicle Engineering Lars Moravy has confirmed production will happen at Gigafactory Texas, with Musk targeting 2027 or 2028, 12 to 18 months after whatever the company demonstrates next month.

SpaceX tells the FCC that Starship Flight 14 is going to orbit

SpaceX filed with the FCC for Starship Flight 14, its first true orbital launch attempt.

Published

on

By

SpaceX has asked the Federal Communications Commission for permission to fly Starlink terminals during Starship’s fourteenth flight test, and the filing lays out a genuine trip to orbit, something the program has never attempted.

Every Starship flight so far, including Flight 13’s successful splashdown in the Indian Ocean on July 24, has flown a suborbital arc that ends with the ship reentering the atmosphere within the same hour it launches. The FCC paperwork describes a mission profile built around an actual orbital insertion instead.

The payload is the other half of the story. Flight 13 carried 20 production Starlink V3 satellites, but because that mission never reached orbit, the satellites reentered along with the ship rather than joining the constellation, something Teslarati covered in detail after SpaceX released footage shot from one of those satellites as it drifted away from Starship in space. Flight 14 is designed to close that gap. If the orbital insertion holds, the roughly 20 V3 satellites onboard would separate into an operational orbit and could eventually go into service, each one rated for about 1 terabit per second of downlink capacity by SpaceX’s own account.

SpaceX announces new Starbase for ‘thousands of Starship launches annually’

Elon Musk first flagged the orbital attempt during SpaceX’s August 4 earnings call, the company’s first as a public entity following its June IPO under the ticker SPCX. He also floated catching the ship with the Starbase tower on the same flight, an idea he walked back on August 20, saying the catch attempt would more likely come “in a few months,” as Teslarati reported at the time. Flight 14 will instead target a splashdown for the ship in the Indian Ocean, the same recovery method used since Flight 12.

Hardware has been catching up to the ambition. Booster 21 completed a full 33-engine static fire on August 28, and Ship 41 finished its own six-engine test the week before. An airspace briefing circulated to pilots on August 20 listed September 15 as the target date, later than the end of August window Musk mentioned on the earnings call, though SpaceX has not confirmed a launch date publicly and Starship schedules routinely slip while hardware and FAA paperwork line up.

The FCC filing itself does not guarantee a launch date. It covers communications authority, and not flight readiness, considering SpaceX still needs Ship 41 fully stacked and cleared by the FAA before Flight 14 can fly. But the filing is a real marker of intent and it puts a specific regulatory process behind what had so far only been Musk’s word on the earnings call.
