SpaceX’s Starship prototype is looking increasingly rocket-like as hop test pad expands

SpaceX workers began welding Starhopper's upper tank dome cap, perhaps the most rocket-like structure yet installed on the craft. (NASASpaceflight - bocachicagal, 02/05/19)

As SpaceX’s South Texas operations continue full steam ahead in pursuit of the first integrated hop tests of a full-scale Starship prototype, the company’s Starhopper and its complementary launch/hop pad are dramatically and visibly evolving on a daily basis.

This week’s progress has been signified by the installation of familiar rocket hardware on the Ship and a burst of construction – centered around pipelaying, plumbing, foundation work, and berm-building – at its pad. Just a few hundred miles north of Boca Chica, SpaceX’s team of propulsion engineers and technicians reached their own dramatic milestone, conducting the first static fire of a finalized version of the Raptor engine set to power Starship and Super Heavy (formerly BFR).

A pad fit for a Starhopper

In the last ~10 days alone (Jan 24-Feb 4), SpaceX pad construction workers and contractors transformed the former dirt mound from a generally flat, planed surface with a spattering of shipping containers and building materials into a hive of welding rigs, propellant and water tanks, major plumbing progress, shaped earth, and the beginnings of new concrete foundations. Thanks to local student Austin Barnard’s reliable drone photography, that pad-specific progress can be more properly visualized.

 

Taken on January 24th and February 4th respectively, the devil is definitely in the details when it comes to SpaceX’s prospective Starhopper pad development. Most notable is the progress made with the rapidly developing propellant plant and ground systems infrastructure in the left half of the images, marked by hundreds of feet of freshly-installed piping meant to support the process of fueling Starhopper with liquid methane and oxygen. For a rocket as powerful as Starhopper (even with just three Raptor engines), cooling both the propellant and the concrete launch and landing pad is no less important, visible in the shape of three large water tanks (lefthand foreground) and a smaller radiator stack (just to the right of two taller, skinnier white tanks.

Aside from the rapid rise of the first BFR propellant farm and its supporting equipment, SpaceX has progressed into the installation of a trio of concrete foundations just to the right of the dirt berm and propellant tank area. Standing as close as it is to said propellant tanks, it seems unlikely that the new foundation-laying is related to the pad (or a stand) meant to support early Starhopper hop tests, although SpaceX’s Falcon 9-era Grasshopper and F9R hop test vehicles operated about the same distance from its propellant infrastructure. SpaceX’s South Texas site also features a sort of satellite pad at its east end (the right side in attached photos) that could have a future as an integration hangar or a secondary landing zone to allow for Starhopper to perform divert tests.

 

Depending on whether SpaceX actually intends to develop the land shown above into an actual full-scale launch facility for BFR (Super Heavy and Starship), it could also remain generally unchanged until Starhopper’s hop test program has been run to completion, at which point everything seen above would likely be rebuilt from scratch to accommodate for any drastic changes in function. SpaceX’s Boca Chica might simply be too small to support a pad capable of launching Super Heavy (nearly twice as powerful as Saturn V at full thrust), measuring in at considerably less than ~10 acres of usable area compared to LC-40’s ~20 acres and Pad 39A’s ~50+ acres. CEO Elon Musk has also hinted at using a giant floating platform for early orbital BFR launches, although that might prove even harder (and more costly) than building a traditional land-based pad.

Becoming a rocket

Meanwhile, the aft engine/fin/tank section of SpaceX’s Starship prototype (unofficially nicknamed Starhopper) has experienced a stream of hardware additions and improvements, modifying its relatively awkward and unfinished steel base with what appear to be Falcon 9-sized quick-disconnect umbilical panels, a functional propellant tank header, and mounting hardware for carbon-overwrapped pressure vessels (COPVs). By using hardware that is proven and easy to manufacture, SpaceX can save a huge amount of time that would otherwise need to be spent engineering subassemblies that (at risk of undervaluing the challenge) are generally known-quantities – more a matter of time and effort than an actual technical hurdle.

While they are clearly still in a rough, unfinished form, Starhopper’s umbilical panels are already easy to recognize when compared alongside Falcon 9’s iconic red and blue panel pairs. In essence, whereas Starhopper has been a largely unknown quantity with no familiar aspects since it began to come together late last year, the Starship prototype has recently had hardware installed that is finally revealing subtle SpaceX signatures in its design and assembly.

Tesla Roadster event gets delayed due to unfavorable weather

Published

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

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.
