SpaceX’s Falcon 9 returns to Earth in first on-site media photos of rocket recovery

Published

on

Thanks to the introduction of a brand new rocket landing pad (LZ-4) less than half a kilometer (~0.3 miles) from SpaceX’s SLC-4 Vandenberg launch complex, members of the media attending the launch were given the first opportunity ever to capture a Falcon booster recovery with remote cameras.

Battling the possibility that SpaceX might forbid landing photos entirely or that Vandenberg’s infamous fog banks would forbid them in a different sense, cautious optimism was ultimately warranted, and picture-perfect weather lead to both an extraordinary light show over much of California and the successful capture of the first unofficial remote images of a Falcon 9 landing.

Following successful separation from Falcon 9’s upper stage and the SAOCOM 1A satellite payload, booster B1048 immediately began a rapid 180-degree flip maneuver, igniting either one or three of its Merlin 1D engines to begin its journey back to the launch site. After cancelling out a velocity of roughly 2 kilometers per second in the wrong direction, B1048 dropped almost straight down from a peak altitude of ~50 km to the landing zone, punctuated by a reentry burn used to protect the rocket from the brunt of atmospheric reentry heating.

A bit less than eight minutes after launch, the first stage broke through the sound barrier, began a single-engine landing burn, deployed its landing legs, and came to a gentle rest at Landing Zone-4, B1048’s second successful launch and landing. Thanks to the low-energy orbit, relatively small satellite, and Falcon 9 Block 5’s healthy performance margins, B1048 likely experienced the most forgiving recovery conditions since SpaceX began landing and reusing boosters, making the rocket a prime candidate to be the first SpaceX Falcon 9 booster to fly three times.

 

Even more so, the fact that B1048 landed barely ~2000 feet from SpaceX’s SLC-4 hangar – where it will be inspected and refurbished – will be a boon for rapid and affordable reusability, thanks to the fact that SpaceX does not have to operate any complex ships, shut down public roads, or transport the recovered rocket more than a few thousand feet. SpaceX confirmed as much during its SAOCOM 1A webcast.

Not yet officially on the schedule, SpaceX’s next Vandenberg launch is expected to be Spaceflight Industries’ SSO-A rideshare mission, carrying around 70 individual satellites of varying masses. Chronically delayed by the complexity of wrangling 70 different spacecraft into a single fairing and – more recently – minor issues with rocket availability, several of SSO-A’s passengers have provided a tentative launch date of November 19th, 2018. If SpaceX is planning to reuse B1048 a third time with SSO-A, that will demand a record-breaking turnaround for the booster, as few as 42 days between landing #2 and launch #3.

Tesla teases new market entrance with confusing and cryptic message

Tesla teased its entrance into a new market with a confusing and what appeared to be cryptic message on the social media platform X.

The company has been teasing its entrance into several markets, including Africa, which would be a first, and South America, where it only operates in Chile.

In September, Tesla started creating active job postings for the Colombian market, hinting it would expand its presence in South America and launch in a new country for the first time in two years.

Tesla job postings seem to show next surprise market entry

The jobs were related to various roles, including Associate Sales Manager, Advisors in Sales and Delivery, and Service Technicians. These are all roles that would indicate Tesla is planning to launch a wide-scale effort to sell, manage, and repair vehicles in the market.

Last night, Tesla posted its latest hint, a cryptic video that seems to show the outline of Colombia, teasing its closer than ever to market entry:

This would be the next expansion into a continent where it does not have much of a presence for Tesla. Currently, there are only two Supercharger locations on the entire continent, and they’re both in Chile.

Tesla will obviously need to expand upon this crucial part of the ownership experience to enable a more confident consumer base in South America as a whole. However, it is not impossible, as many other EV charging infrastructures are available, and home charging is always a suitable option for those who have access to it.

Surprisingly, Tesla seems to be more concerned about these middle-market countries as opposed to the larger markets in South America, but that could be by design.

If Tesla were to launch in Brazil initially, it may not be able to handle the uptick in demand, and infrastructure expansion could be more difficult. Brazil may be on its list in the upcoming years, but not as of right now.

Tesla expands crucial Supercharging feature for easier access

It is a useful tool, especially during hours of congestion. However, it has not been super effective for those who drive non-Tesla EVs, as other OEMs use UI platforms like Google’s Android Auto or Apple’s iOS.

Tesla has expanded a crucial Supercharging feature that helps owners identify stall availability at nearby locations.

Tesla said on Tuesday night that its “Live Availability” feature, which shows EV owners how many stalls are available at a Supercharger station, to Google Maps, a third-party app:

Already offering it in its own vehicles, the Live Availability feature that Teslas have is a helpful feature that helps you choose an appropriate station with plugs that are immediately available.

A number on an icon where the Supercharger is located lets EV drivers know how many stalls are available.

It is a useful tool, especially during hours of congestion. However, it has not been super effective for those who drive non-Tesla EVs, as other OEMs use UI platforms like Google’s Android Auto or Apple’s iOS.

Essentially, when those drivers needed to charge at a Supercharger that enables non-Tesla EVs to plug in, there was a bit more of a gamble. There was no guarantee that a plug would be available, and with no way to see how many are open, it was a risk.

Tesla adding this feature allows people to have a more convenient and easier-to-use experience if they are in a non-Tesla EV. With the already expansive Supercharger Network being available to so many EV owners, there is more congestion than ever.

This new feature makes the entire experience better for all owners, especially as there is more transparency regarding the availability of plugs at Supercharger stalls.

It will be interesting to see if Tesla is able to expand on this new move, as Apple Maps compatibility is an obvious goal of the company’s in the future, we could imagine. In fact, this is one of the first times an Android Auto feature is available to those owners before it became an option for iOS users.

Apple owners tend to get priority with new features within the Tesla App itself.

Elon Musk’s Boring Co goes extra hard in Nashville with first rock-crushing TBM

The Boring Company’s machine for the project is now in final testing.

The Boring Company is gearing up to tackle one of its toughest projects yet, a new tunnel system beneath Nashville’s notoriously tough limestone terrain. Unlike the soft-soil conditions of Las Vegas and Austin, the Music City Loop will require a “hard-rock” boring machine capable of drilling through dense, erosion-resistant bedrock. 

The Boring Company’s machine for the project is now in final testing.

A boring hard-rock tunneling machine

The Boring Company revealed on X that its new hard-rock TBM can generate up to 4 million pounds of grip force and 1.5 million pounds of maximum thrust load. It also features a 15-filter dust removal system designed to keep operations clean and efficient during excavation even in places where hard rock is present.

Previous Boring Co. projects, including its Loop tunnels in Las Vegas, Austin, and Bastrop, were dug primarily through soft soils. Nashville’s geology, however, poses a different challenge. Boring Company CEO and President Steve Davis mentioned this challenge during the project’s announcement in late July.

“It’s a tough place to tunnel, Nashville. If we were optimizing for the easiest places to tunnel, it would not be here. You have extremely hard rock, like way harder than it should be. It’s an engineering problem that’s fairly easy and straightforward to solve,” Davis said.

Nashville’s limestone terrain

Experts have stated that the city’s subsurface conditions make it one of the more complex tunneling environments in the U.S. The Outer Nashville Basin is composed of cherty Mississippian-age limestone, a strong yet soluble rock that can dissolve over time, creating underground voids and caves, as noted in a report from The Tennessean.

Jakob Walter, the founder and principal engineer of Haushepherd, shared his thoughts on these challenges. “Limestone is generally a stable sedimentary bedrock material with strength parameters that are favorable for tunneling. Limestone is however fairly soluble when compared to other rack materials, and can dissolve over long periods of time when exposed to water. 

“Unexpected encounters with these features while tunneling can result in significant construction delays and potential instability of the excavation. In urban locations, structures at the ground surface should also be constantly monitored with robotic total stations or similar surveying equipment to identify any early signs of movement or distress,” he said.
