The European Space Agency (ESA) has published an unusual press release – in the form of a Twitter thread – specifically blaming SpaceX’s nascent Starlink constellation for a collision avoidance maneuver recently performed by Aeolus, a scientific spacecraft in low Earth orbit (LEO). SpaceX reportedly refused to move its Starlink satellite, triggering the maneuver.

SpaceX launched an extensive Starlink beta test on May 23rd, 2019, placing an unprecedented 60 satellites in LEO. Discussed earlier today on Teslarati, 50 of those 60 satellite prototypes have reached their final 550 km (340 mi) orbits and are functioning as intended, while 5 have paused their orbit-raising, 3 have been declared dead, and 2 are intentionally lowering their orbits as an end-of-life simulation.

Update: SpaceX has released an official statement on the matter.

“Our Starlink team last exchanged an email with the Aeolus operations team on August 28, when the probability of collision was only in the 2.2e-5 range (or 1 in 50k), well below the 1e-4 (or 1 in 10k) industry standard threshold and 75 times lower than the final estimate. At that point, both SpaceX and ESA determined a maneuver was not necessary. Then, the U.S. Air Force’s updates showed the probability increased to 1.69e-3 (or more than 1 in 10k) but a bug in our on-call paging system prevented the Starlink operator from seeing the follow on correspondence on this probability increase – SpaceX is still investigating the issue and will implement corrective actions. However, had the Starlink operator seen the correspondence, we would have coordinated with ESA to determine best approach with their continuing with their maneuver or our performing a maneuver.”

–SpaceX, 09/03/2019

Additionally, Starlink satellites have already reportedly performed 16 autonomous collision avoidance maneuvers (sans human operator interference) and SpaceX confirmed that the satellite ESA was worried about is fully operational while it continues its deorbit maneuver.


On one hand, ESA’s description of events is bizarre and dubious, at points. ESA Operations tweeted that “it is very rare to perform collision avoidance maneuvers with active satellites”, while the very next tweet stated that “ESA performed 28 collision avoidance maneuvers [in 2018]”, meaning that the procedure is roughly biweekly for ESA alone.

Meanwhile, Matt Desch – CEO of Iridium, the owner and operator of one of the largest LEO constellations ever flown – stated that its Iridium NEXT satellites perform similar maneuvers weekly, without the need to “put out a press release to say who [Iridium] maneuvered around”. In simple terms, collision avoidance maneuvers are extremely common and extremely routine and are a fundamental part of operating satellites on orbit – be it one, ten, or ten thousand.

However, spaceflight journalist Jonathan O’Callaghan was told by sources in ESA that the space agency had directly contacted SpaceX with concerns about a possible Starlink-Aeolus collision and the company refused to move their spacecraft in cooperation. This left ESA’s Aeolus to perform the maneuver.

From the perspective of O’Callaghan’s sourced information, SpaceX certainly appears to be in the wrong in this case. However, the current story is extremely patchy, and more information is needed to paint a true-to-life picture of events. Was SpaceX’s refusal to move based on an inability to move one of the two satellites it is intentionally deorbiting? Is the company simply confident in what it has described as a suite of autonomous collision avoidance hardware and software installed on each Starlink satellite?

Either way, if SpaceX actually is/was as terse and uncommunicative as O’Callaghan’s sources have painted the company, it is an extremely bad look. For SpaceX to successfully operate hundreds of Starlink satellites, let alone its constellation’s full ~11,800, good spaceflight stewardship and hand-in-hand cooperation with other major (and minor) operators is an absolute necessity. If SpaceX acts like the bully in the room and simply ignores or avoids cooperation and fails to take responsibility and help maintain current standards of collision avoidance, the company will very quickly find itself surrounded by newly made enemies like ESA.

Tesla Roadster event gets delayed due to unfavorable weather

Published

Credit: Tesla

Tesla is delaying its event for the Roadster, moving it from this Thursday, October 1, to Thursday, October 15, due to unfavorable weather.

The company has said it has been tracking the weather for this Thursday closely with local meteorologists, and because the event can only be held outside, Tesla is making the call to delay it:

“We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule. New date is October 15. Additional details to follow.”

We are sure that this is bringing back PTSD for some Tesla fans, and we know it is not ideal, but this also reveals some things about the event. Tesla said that this can only be held outdoors, meaning it bodes well for the rumors that the vehicle could potentially hover.

Some believe that this was essentially confirmed by the FAA airspace restriction they were granted, but this could have been for a drone show or to keep drones from spying on the event.

Tesla Roadster is available for order once again following brief hold

The Roadster event has been long-awaited, and it is unfortunate that the weather is going to keep us all waiting a little bit longer.

The Tesla Roadster will be unveiled in Waco, Texas.

SpaceX turned a heralding moment for Starship into its greatest

Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.

SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.

The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.

Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.

The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.

SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.

Tesla Cybercab fleet doubles to well over 100 units

Published

Tesla quietly doubled the size of its Cybercab fleet within the Robotaxi program in Austin, Texas, over the weekend to well over 100 units.

The move not only establishes more of the steering-wheel-less and pedal-less vehicles within the ride-sharing fleet Tesla has been operating for a year, but it also solidifies a more robust Robotaxi fleet as a whole.

Riders started receiving notifications from the Robotaxi app that stated: “Cybercab fleet has doubled: more rides available.”

Tesla first launched rides in the Cybercab in early September, although the Robotaxi fleet has been active for over a year, as rides began last Summer. Cybercab is truly Tesla’s most crucial vehicle release yet, as it is the first car any company has built that is geared toward full-fledged and end-to-end autonomy, never needing human intervention for anything.

Only available in Austin at the current time, Cybercab has two seats and has been spotted testing around various U.S. states and regions; Tesla plans to deploy the Cybercab in various U.S. cities in the coming months as a best-case scenario.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

The availability of the Cybercab has doubled from just 58 units last Monday to 125 the following Friday. Marking a substantial increase in Cybercab availability, the additional ride-sharing units are more than welcome, as wait times for Cybercabs, especially, were quite high.

The dramatic increase is a sign that demand for Robotaxi is growing and Tesla is feeling more confident that its driverless ride-hailing suite, especially its Full Self-Driving software, is able to handle any traffic situation without explicit direction or supervision from a human being.
