SpaceX Receives Pentagon Help To Develop New Rocket Engine

SpaceX has been awarded a Pentagon contract for development of its next generation Raptor rocket engine, which is 6 times more powerful than the Merlin engine it uses now.

The U.S. Department of Defense has announced a $33.7 million dollar contract awarded to SpaceX for the development of the Raptor rocket propulsion system prototype as part of the Evolved Expendable Launch Vehicle (EELV) program. The Raptor engine burns a mixture of liquid methane and liquid oxygen, and designed to produce six times the thrust of the Merlin engines SpaceX recently used on its historic mission that saw its first stage rocket land itself back on earth from orbit. Here’s why that’s important to SpaceX.

Currently, virtually all large military satellites launches are done by the United Launch Alliance, a consortium made up of Lockheed Martin and Boeing. In 2013, ULA was awarded a $1.1 billion contract for multiple launches using Lockheed Martin’s Atlas V or Boeing’s Delta IV rockets. SpaceX wants a piece of that pie.

According to Motley Fool, both ULA rockets use RD-180 engines purchased from Russia’s Energomash, which is majority owned by the Russian government. After Russia’s 2014 actions in Crimea, the US slapped economic sanctions on it and Energomash. They in turn decided they would not sell any more rocket engines to ULA. The US Congress responded to that by prohibiting the US military from using any Russian rocket engines to launch its satellites.

But Houston, we have a problem. No rocket engines means no satellite launches. ULA placed its hopes on either Blue Origin or Aerojet Rocketdyne coming up with a new rocket engine to replace the RD-180 it can no longer buy from Energomash, but that process could take 3 or 4 years to complete.

So Congress has relented somewhat. Buried in the more than 1,000 page appropriations bill approved just before Christmas, it gave ULA approval to buy a supply of RD-180s — just enough to keep it in the military launch business for the time being. But clearly, America needs American made rockets for its various space programs going forward.

Enter SpaceX, which received authorization to bid for Pentagon business last year. The next generation Raptor engines will be used to power the upcoming Falcon 9 “heavy lift” and “super heavy lift” rockets. The more powerful Falcon 9 could be used in place of the traditional satellite launching vehicles from Lockheed and Boeing. That would open the door for lucrative government contracts to flow to SpaceX instead of ULA.

There is a lot of money up for grabs launching satellites for the military over next several years. SpaceX has been funding its Raptor engine program out of its own pocket up until now, but under terms of the new contract, the Pentagon will provide $1 in development funding for every $2 invested by SpaceX.

Lockheed and Boeing might be giving way to the Aerospace upstart. SpaceX, like every venture Elon Musk is involved with, will put every ounce of effort into getting to the finish line ahead of everyone else.

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.
