SpaceX’s spectacular USSF-67 Falcon Heavy launch in photos
On January 15th, SpaceX’s Falcon Heavy rocket lifted off for the second time in 75 days to launch another batch of US military payloads into orbits tens of thousands of kilometers above Earth’s surface.
Six and a half hours later, the US Space Systems Command (SSC) confirmed that Falcon Heavy had again completed the exceptionally difficult launch without issue. To deliver the USSF-67 mission’s payloads directly to geosynchronous orbit (GSO), the giant SpaceX rocket had to sacrifice one of its potentially reusable boosters and complete a complex six-hour ballet of rolls, burns, and spacecraft deployments. And for the second time in a row, Falcon Heavy did so without apparent issue.
In an SSC press release [PDF], Maj. Gen. Stephen Purdy, program executive officer for Assured Access to Space, said that the group “had another fantastic launch today on a Falcon Heavy.” He added that “while the launch itself was impressive,” he was “most proud of the fact that we placed important [national] capabilities into space.” And an impressive launch it certainly was.

A Falcon (Heavy) spectacle
As previously discussed, USSF-67 was Falcon Heavy’s first twilight launch. The extraordinary cadence of SpaceX’s workhorse Falcon 9 rocket, which Falcon Heavy is derived from, caused twilight launches and the incredible light shows they can produce to become a fairly routine phenomena. But just under five years after its February 2018 debut, there had still never been a Falcon Heavy launch ‘jellyfish’ or ‘nebula.’ That thankfully changed on Sunday.
The rocket lifted off just ten or so minutes after sunset and soared into the fading purple skies. Those skies were still relatively bright at ground-level, reducing the amount of contrast, but the resulting light show was still spectacular as Falcon Heavy and its immense exhaust plume ascended back into the sunlight. The artificial sunrise lit up that pillar-like plume with the colors of sunrise and, eventually, bright daylight.
Close-up views enabled by tracking telescopes captured the true drama, which began shortly after Falcon Heavy’s twin side boosters separated from the rocket’s main core stage and upper stage, flipped around, and ignited their engines to fly back to the Florida coast they’d only just lifted off from. As the nine-engine center core continued towards space, each booster fired up one and then three Merlin 1D engines for their boostback burns.
A view from Astronomy Live captured the moment of boostback burn ignition, during which the side boosters visibly blasted ‘craters’ the Falcon Heavy center core’s much more powerful plume. As those plumes interacted, the fluid dynamics and light produced by multiple Merlin 1D engines combined to create chaotic whisps of orange, red, and yellow – akin to an exploding nebula. The moments prior were also spectacular as the two side boosters, lit up by direct sunlight against the nearly black sky, began gently floating away from the center core and spinning around with bursts from several nitrogen gas thrusters – a brief moment of serenity before the violence of engine ignition.
On a chariot of fire
But as Maj. Gen. Purdy noted, the purpose of USSF-67 – spectacle aside – was to carry a number of important payloads into orbit.
“After both side boosters touched down, SpaceX ended its live coverage at the request of the Space Force, reiterating the mission’s secretive customer and nature. The USSF hasn’t confirmed much about the USSF-67 mission’s payloads, but Falcon Heavy is known to be carrying a geostationary communications relay satellite called CBAS-2 and likely built by Boeing. CBAS-2 is joined by Northrop Grumman’s third Long Duration Propulsive EELV or LDPE-3A, a combination of a propulsive kick stage and a satellite. LDPE-3A is carrying a collection of rideshare satellites and payloads and is designed to operate for months in orbit. Using USSF-44 as a guide, the total USSF-67 payload could weigh roughly 3.75 to 4.75 tons (8,250-10,500 lb).”

The same SSC press release provides more detail, noting that LDPE-3A carries two hosted payloads – Catcher and WASSAT. Catcher is a space weather instrument developed by the Aerospace Corporation, while WASSAT is a prototype [PDF] of a wide-angle observation instrument designed to track other satellites in GSO. LDPE is also hosting “three payloads developed by the Space Rapid Capabilities Office (SRCO),” including “two operational prototypes for enhanced situational awareness, and an operational prototype crypto/interface encryption payload providing secure space-to-ground communications capability.”
Two down, one to go
For Falcon Heavy side boosters B1064 and B1065, both of which supported USSF-44 and USSF-67, their missions are far from over. Their second successful side-by-side landing has cleared the boosters to be reused on a third US military launch called USSF-52. Originally known as AFSPC-52, the mission was Falcon Heavy’s first operational US military launch contract and the first time the rocket beat competitor United Launch Alliance (ULA) during a competitive procurement.
Next Spaceflight reports that USSF-52 is scheduled to launch no earlier than April 10th, 2023, less than three months from now. Once that mission is complete, Falcon Heavy will have no more US military missions on contract, although more will almost certainly be rewarded sooner than later. USSF-52 is sandwiched between two other Falcon Heavy launches. Next Spaceflight also reports that Falcon Heavy could launch the ViaSat-3 communications satellite as early as March 2023 and the Jupiter-3 (EchoStar 24) communications satellite as early as May 2023, making for a busy 90 days.
For that trio to happen as scheduled, SpaceX will have to beat Falcon Heavy’s record 75-day turnaround, which has coincidentally (?) occurred twice: first between Arabsat 6A and STP-2, and again between USSF-44 and USSF-67. Including USSF-67, SpaceX has up to five Falcon Heavy launches scheduled this year.

Elon Musk’s X will start using a Tesla-like software update strategy
The initiative seems designed to accelerate updates to the social media platform, while maintaining maximum transparency.
Elon Musk’s social media platform X will adopt a Tesla-esque approach to software updates for its algorithm.
The initiative seems designed to accelerate updates to the social media platform, while maintaining maximum transparency.
X’s updates to its updates
As per Musk in a post on X, the social media company will be making a new algorithm to determine what organic and advertising posts are recommended to users. These updates would then be repeated every four weeks.
“We will make the new 𝕏 algorithm, including all code used to determine what organic and advertising posts are recommended to users, open source in 7 days. This will be repeated every 4 weeks, with comprehensive developer notes, to help you understand what changed,” Musk wrote in his post.
The initiative somewhat mirrors Tesla’s over-the-air update model, where vehicle software is regularly refined and pushed to users with detailed release notes. This should allow users to better understand the details of X’s every update and foster a healthy feedback loop for the social media platform.
xAI and X
X, formerly Twitter, has been acquired by Elon Musk’s artificial intelligence startup, xAI last year. Since then, xAI has seen a rapid rise in valuation. Following the company’s the company’s upsized $20 billion Series E funding round, estimates now suggest that xAI is worth tens about $230 to $235 billion. That’s several times larger than Tesla when Elon Musk received his controversial 2018 CEO Performance Award.
As per xAI, the Series E funding round attracted a diverse group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group, among others. Strategic partners NVIDIA and Cisco Investments also continued support for building the world’s largest GPU clusters.

Tesla FSD Supervised wins MotorTrend’s Best Driver Assistance Award
The decision marks a notable reversal for the publication from prior years, with judges citing major real-world improvements that pushed Tesla’s latest FSD software ahead of every competing ADAS system.
Tesla’s Full Self-Driving (Supervised) system has been named the best driver-assistance technology on the market, earning top honors at the 2026 MotorTrend Best Tech Awards.
The decision marks a notable reversal for the publication from prior years, with judges citing major real-world improvements that pushed Tesla’s latest FSD software ahead of every competing ADAS system. And it wasn’t even close.
MotorTrend reverses course
MotorTrend awarded Tesla FSD (Supervised) its 2026 Best Tech Driver Assistance title after extensive testing of the latest v14 software. The publication acknowledged that it had previously criticized earlier versions of FSD for erratic behavior and near-miss incidents, ultimately favoring rivals such as GM’s Super Cruise in earlier evaluations.
According to MotorTrend, the newest iteration of FSD resolved many of those shortcomings. Testers said v14 showed far smoother behavior in complex urban scenarios, including unprotected left turns, traffic circles, emergency vehicles, and dense city streets. While the system still requires constant driver supervision, judges concluded that no other advanced driver-assistance system currently matches its breadth of capability.
Unlike rival systems that rely on combinations of cameras, radar, lidar, and mapped highways, Tesla’s FSD operates using a camera-only approach and is capable of driving on city streets, rural roads, and freeways. MotorTrend stated that pure utility, the ability to handle nearly all road types, ultimately separated FSD from competitors like Ford BlueCruise, GM Super Cruise, and BMW’s Highway Assistant.
High cost and high capability
MotorTrend also addressed FSD’s pricing, which remains significantly higher than rival systems. Tesla currently charges $8,000 for a one-time purchase or $99 per month for a subscription, compared with far lower upfront and subscription costs from other automakers. The publication noted that the premium is justified given FSD’s unmatched scope and continuous software evolution.
Safety remained a central focus of the evaluation. While testers reported collision-free operation over thousands of miles, they noted ongoing concerns around FSD’s configurable driving modes, including options that allow aggressive driving and speeds beyond posted limits. MotorTrend emphasized that, like all Level 2 systems, FSD still depends on a fully attentive human driver at all times.
Despite those caveats, the publication concluded that Tesla’s rapid software progress fundamentally reshaped the competitive landscape. For drivers seeking the most capable hands-on driver-assistance system available today, MotorTrend concluded Tesla FSD (Supervised) now stands alone at the top.

Elon Musk’s Grokipedia surges to 5.6M articles, almost 79% of English Wikipedia
The explosive growth marks a major milestone for the AI-powered online encyclopedia, which was launched by Elon Musk’s xAI just months ago.
Elon Musk’s Grokipedia has grown to an impressive 5,615,201 articles as of today, closing in on 79% of the English Wikipedia’s current total of 7,119,376 articles.
The explosive growth marks a major milestone for the AI-powered online encyclopedia, which was launched by Elon Musk’s xAI just months ago. Needless to say, it would only be a matter of time before Grokipedia exceeds English Wikipedia in sheer volume.
Grokipedia’s rapid growth
xAI’s vision for Grokipedia emphasizes neutrality, while Grok’s reasoning capabilities allow for fast drafting and fact-checking. When Elon Musk announced the initiative in late September 2025, he noted that Grokipedia would be an improvement to Wikipedia because it would be designed to avoid bias.
At the time, Musk noted that Grokipedia “is a necessary step towards the xAI goal of understanding the Universe.”
Grokipedia was launched in late October, and while xAI was careful to list it only as Version 0.1 at the time, the online encyclopedia immediately earned praise. Wikipedia co-founder Larry Sanger highlighted the project’s innovative approach, noting how it leverages AI to fill knowledge gaps and enable rapid updates. Netizens also observed how Grokipedia tends to present articles in a more objective manner compared to Wikipedia, which is edited by humans.
Elon Musk’s ambitious plans
With 5,615,201 total articles, Grokipedia has now grown to almost 79% of English Wikipedia’s article base. This is incredibly quick, though Grokipedia remains text-only for now. xAI, for its part, has now updated the online encyclopedia’s iteration to v0.2.
Elon Musk has shared bold ideas for Grokipedia, including sending a record of the entire knowledge base to space as part of xAI’s mission to preserve and expand human understanding. At some point, Musk stated that Grokipedia will be renamed to Encyclopedia Galactica, and it will be sent to the cosmos.
“When Grokipedia is good enough (long way to go), we will change the name to Encyclopedia Galactica. It will be an open source distillation of all knowledge, including audio, images and video. Join xAI to help build the sci-fi version of the Library of Alexandria!” Musk wrote, adding in a later post that “Copies will be etched in stone and sent to the Moon, Mars and beyond. This time, it will not be lost.”
