Hawthorne, we have a problem: SpaceX has too many boosters
Over the course of two years of concerted effort, SpaceX has matured its program of reusable rocketry into a truly staggering success. Over the 24 months since SpaceX first successful recovery of a Falcon 9 booster, there have been stumbles as recovery improved, but overall the company has accomplished 20 near-flawless landings of boosters over that period. Perhaps more impressively, following a handful of failed recovery attempts in 2016, SpaceX has successfully recovered 15 boosters without incident, with the vast majority of those attempts occurring in 2017.
2017 has ultimately been the best year yet for the launch company, marked by what will likely be 18 successful missions (after Iridium-4) for Falcon 9, five commercial reuses of flight-proven boosters, the activation of three essentially new launch facilities, and numerous additional accomplishments behind the scenes as the inaugural launches of Falcon Heavy and Crew Dragon rapidly approach. The success of reusability is arguably the sticking point here, and that success has meant that SpaceX rapidly accumulated a huge stock of recovered Falcon 9s, often to the extent that Elon Musk sometimes joked about running out of space for boosters.

While it may not be immediately clear if SpaceX is legitimately running out of space with which to store its fleet of boosters, reports of first stages being mothballed or even scrapped suggest that space may indeed be at a premium, or at least indicate that SpaceX is growing increasingly pragmatic as its reuse expertise expands.
This is to say that while there may be room to store a few additional boosters, the reality is that older Block 3 Falcon 9s were simply not designed with an expectation that they would affordably survive multiple reuses. As such, it should come as little surprise that SpaceX is choosing to expend at least a couple of upcoming launches featuring reused boosters. As of December 19, public information indicates that the West Coast launch of Iridium-4 – scheduled for Dec. 22 – will not attempt first stage recovery. While somewhat sad, the decision is entirely rational, and it appears all but certain that Iridium-4 will at a minimum feature an attempt at fairing recovery aboard the highly-modified recovery vessel Mr. Steven.

Public Falcon 9 tracking efforts on forums like Reddit and NASASpaceflight indicate that Block 3 boosters include 1029-1038, all of which debuted with their first launches in 2017, beginning with Iridium-1 in January. Of those ten distinct boosters, only two currently lack any future missions, 1032 and 1038; SpaceX has essentially worked the Block 3 fleet to its end-of-life, and that end will be efficiently sped up by simply expending those final reused boosters if or when they are reflown, Iridium-4 included.
For now, we only use those on super hot reentry missions. Will go to all Ti with Falcon 9 V5, which is a few months away.

Expending those older flight-proven boosters will allow SpaceX to both figuratively and literally replace Falcon 9’s less capable predecessors with Block 4s and eventually Block 5s, both of which are at least marginally more reusable than their predecessors. As reported by Musk himself a few days ago, Falcon 9 Block 5 is expected within a few months. Block 5 has seen considerable modifications made to Falcon 9, and all of those changes are intended to improve ease of reuse: SpaceX’s official goal for the upgrade is to enabled Falcon 9 first stages to be reflown as many as 10 times with little to no refurbishment and a lifespan of 100 flights with significant periodic refurbishment. As a result, it is possible that 2018 might feature a similar period of reused Block 4 launches sans any attempted recoveries.
In the meantime, we can wish the fairing recovery teams the best of luck and mourn several of the pioneers of reusable rocketry. Here’s to hoping that we are treated to a live view of each booster’s demise in homage to their achievements.

Starlink restrictions are hitting Russian battlefield comms: report
The restrictions have reportedly disrupted Moscow’s drone coordination and frontline communications.
SpaceX’s decision to disable unauthorized Starlink terminals in Ukraine is now being felt on the battlefield, with Ukrainian commanders reporting that Russian troops have struggled to maintain assault operations without access to the satellite network.
The restrictions have reportedly disrupted Moscow’s drone coordination and frontline communications.
Lt. Denis Yaroslavsky, who commands a special reconnaissance unit, stated that Russian assault activity noticeably declined for several days after the shutdown. “For three to four days after the shutdown, they really reduced the assault operations,” Yaroslavsky said.
Russian units had allegedly obtained Starlink terminals through black market channels and mounted them on drones and weapons systems, despite service terms prohibiting offensive military use. Once those terminals were blocked, commanders on the Ukrainian side reported improved battlefield ratios, as noted in a New York Post report.
A Ukrainian unit commander stated that casualty imbalances widened after the cutoff. “On any given day, depending on your scale of analysis, my sector was already achieving 20:1 (casuality rate) before the shutdown, and we are an elite unit. Regular units have no problem going 5:1 or 8:1. With Starlink down, 13:1 (casualty rate) for a regular unit is easy,” the unit commander said.
The restrictions come as Russia faces heavy challenges across multiple fronts. A late January report from the Center for Strategic and International Studies estimated that more than 1.2 million Russian troops have been killed, wounded, or gone missing since February 2022.
The Washington-based Institute for the Study of War also noted that activity from Russia’s Rubikon drone unit declined after Feb. 1, suggesting communications constraints from Starlink’s restrictions may be limiting operations. “I’m sure the Russians have (alternative options), but it takes time to maximize their implementation and this (would take) at least four to six months,” Yaroslavsky noted.

Tesla Korea hiring AI Chip Engineers amid push for high-volume AI chips
Tesla Korea stated that it is seeking “talented individuals to join in developing the world’s highest-level mass-produced AI chips.”
In a recent post on X, Tesla Korea announced that it is hiring AI Chip Design Engineers as part of a project aimed at developing what the company describes as the world’s highest-volume AI chips. CEO Elon Musk later amplified the initiative.
Tesla Korea stated that it is seeking “talented individuals to join in developing the world’s highest-level mass-produced AI chips.”
“This project aims to develop AI chip architecture that will achieve the highest production volume in the world in the future,” Tesla Korea wrote in its post on X.
As per Tesla Korea, those who wish to apply for the AI Chip Design Engineer post should email Ai_Chips@Tesla.com and include “the three most challenging technical problems you have solved.”
Elon Musk echoed the hiring push in a separate post. “If you’re in Korea and want to work on chip design, fabrication or AI software, join Tesla!” he wrote.
The recruitment effort in South Korea comes as Tesla accelerates development of its in-house AI chips, which power its Full Self-Driving (FSD) system, Optimus humanoid robot, and data center training infrastructure.
Tesla has been steadily expanding its silicon development teams globally. In recent months, the company has posted roles in Austin and Palo Alto for silicon module process engineers across lithography, etching, and other chip fabrication disciplines, as noted in a Benzinga report.
Tesla Korea’s hiring efforts align with the company’s long-term goal of designing and producing AI chips at massive scale. Musk has previously stated that Tesla’s future AI chips could become the highest-volume AI processors in the world.
The move also comes amid Tesla’s broader expansion into AI initiatives. The company recently committed about $2 billion into xAI as part of a Series E funding round, reinforcing its focus on artificial intelligence across vehicles, robotics, and compute infrastructure.

SpaceX and xAI tapped by Pentagon for autonomous drone contest
The six-month competition was launched in January and is said to carry a $100 million award.
SpaceX and its AI subsidiary xAI are reportedly competing in a new Pentagon prize challenge focused on autonomous drone swarming technology, as per a report from Bloomberg News.
The six-month competition was launched in January and is said to carry a $100 million award.
Bloomberg reported that SpaceX and xAI are among a select group invited to participate in the Defense Department’s effort to develop advanced drone swarming capabilities. The goal is reportedly to create systems that can translate voice commands into digital instructions and manage fleets of autonomous drones.
Neither SpaceX, xAI, nor the Pentagon’s Defense Innovation Unit has commented on the report, and Reuters said it could not independently verify the details.
The development follows SpaceX’s recent acquisition of xAI, which pushed the valuation of the combined companies to an impressive $1.25 trillion. The reported competition comes as SpaceX prepares for a potential initial public offering later this year.
The Pentagon has been moving to speed up drone deployment and expand domestic manufacturing capacity, while also seeking tools to counter unauthorized drone activity around airports and major public events. Large-scale gatherings scheduled this year, including the FIFA World Cup and America250 celebrations, have heightened focus on aerial security.
The reported challenge aligns with broader Defense Department investments in artificial intelligence. Last year, OpenAI, Google, Anthropic, and xAI secured Pentagon contracts worth up to $200 million each to advance AI capabilities across defense applications.
Elon Musk previously joined AI and robotics researchers in signing a 2015 open letter calling for a ban on offensive autonomous weapons. In recent years, however, Musk has spoken on X about the strengths of drone technologies in combat situations.
