SpaceX’s massive Falcon Heavy rocket aims for December 29 inaugural launch

Published

on

Based on information released by NASASpaceflight.com, a highly reliable source of insider details, SpaceX’s first Falcon Heavy rocket could roll out to the LC-39A launch pad before the end of November, less than a month away. While the first roll-out (or two) will be dedicated solely to “Wet Dress Rehearsals” (WDR), this will be the first time the iconic vehicle makes it to the pad, and will be a historic event regardless of what follows.

No earlier than (NET) “late-November”, the first WDR will see Falcon Heavy go through the usual motions of propellant loading while also conducting an array of systems checks and validations to verify that things are proceeding as expected. This first test will not culminate in any sort of hot-fire, and is more intended to verify that the massive rocket is playing well with the modifications made to the launch pad and the Transporter/Erector/Launcher (TEL) that carries it from the integration facilities to the pad. If major issues come up, they will be dealt with and followed by a second identical WDR. If there are no issues with the first WDR, the second rehearsal could smoothly morph into the first static fire of the integrated vehicle.

As Chris Gebhardt of NSF discusses in some detail, the first Falcon Heavy static fire(s) conducted at LC-39A will be of groundbreaking importance, as SpaceX is currently unable to test fully-integrated Falcon Heavy vehicles at its McGregor, Texas facilities due to the rocket’s sheer power. A lot, thus, rests on these first static fires, currently scheduled to begin around December 15th.

Given the distinctly experimental nature of Falcon Heavy’s inaugural launch, specific dates are best taken as general placemarkers, and the actual dates of the first flow depend entirely upon the tests that precede each subsequent step. Nevertheless, the dates provided by NASASpaceflight point to Falcon Heavy’s first static fire on December 15th, followed two weeks later by a tentative launch date of December 29th.

Staying focused on Mars: Is Falcon Heavy necessary?

Even an uncertain launch date of that specificity is still a historic event for Falcon Heavy, long lampooned and straw-manned as an example of SpaceX’s silly pie-in-the-sky claims and Elon Musk’s oversimplification of complex engineering tasks. There is a grain of truth to such contentions, but they tend to miss the point by huge margins. The actual market for mid-level heavy-lift launch vehicles like Falcon Heavy is quite simply too small to be a major motivator for a commercial launch company like SpaceX. One must remember that SpaceX was not founded to be a run-of-the-mill launch provider. The company’s goal, as has been reiterated ad infinitum, is “enabling human life on Mars”, something that has explicitly prefaced every single job posting on the company’s website for more than half a decade.

For a time, it appeared that Falcon Heavy might eventually be used to enable SpaceX’s Red Dragon program, intended to field-test the technologies needed for month-long cruises in deep space and landing large payloads on Mars. However, the program was cancelled earlier this year, in favor of what Musk called “vastly bigger ships”. Indeed, updated Mars plans unveiled on September 29th showed that SpaceX was forging ahead with an updated BFR and BFS, and hopes to fly its first missions to Mars in 2022.

Falcon Heavy will admittedly become the most powerful operational launch vehicle when it first lifts off in approximately two months, and it will likely retain that title well into 2020, when NASA’s Space Launch System may conduct its first launch. However, regardless of the impressive technological accomplishments it will embody, Falcon Heavy simply is not powerful or affordable enough to ever realistically enable a sustained human presence on Mars. SpaceX does have a small number of customers actively waiting with payloads for Falcon Heavy – its second mission is currently penciled in for June 2018 – and it is reasonable to assume that some or all of those missions will be completed simply out of due diligence. SpaceX may also be motivated to continue the Falcon Heavy program as a possible entrant in a recently-announced USAF competition meant to partially fund the development of multiple US-built heavy-lift launch vehicles.

More simply still, experience derived from igniting and simultaneously operating Falcon Heavy’s 27 Merlin 1D rocket engines will to some extent benefit BFR’s development and operations, as the conceptual vehicle is currently expected to host 31 Raptor engines on its first stage.

Whether Falcon Heavy is to remain a development or production priority for SpaceX after its first several launches is unclear, but the vehicle’s inaugural launch and all subsequent launches are bound to be spectacles to behold. The company’s second Florida-based launch pad, intended to support two simultaneous landings of Falcon Heavy’s side boosters, appears to be nearly complete. At LC-39A, the facility’s TEL already sports major visible modifications necessary for it to operate with Falcon Heavy. All three of the first Heavy’s first stage cores have already completed hot-fire testings in Texas and are now located at Cape Canaveral, awaiting their first integrated tests later this month. Delays to the December 29th launch date are probable, but the various components needed for Falcon Heavy’s first launch have truly come together, and the vehicle’s launch is now simply a matter of “when”. Place your bets!

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.
