SpaceX's Dragon spacecraft photobombed in orbit by solar eclipse
On December 26th, SpaceX’s second-to-last Cargo Dragon spacecraft was photobombed in orbit by the shadow cast on Earth by a solar eclipse, likely a little over a week before the vehicle is set to reenter the atmosphere and splash down in the Pacific Ocean.
Cargo Dragon lifted off atop a rare new Falcon 9 booster – B1059 – on December 5th, carrying around 2600 kg (5800 lb) of cargo inside on the flight-proven capsules third launch into Earth orbit. After a quick three-day journey from its parking orbit to the International Space Station (ISS), Dragon was successfully captured by the station’s astronauts with a robotic arm and berthed to the orbital outpost, where the crew quickly unloaded its cargo of food, consumables, science, and equipment.
Shortly after liftoff, Falcon 9 B1059 completed its first successful landing – a bit of a surprise ordeal aboard drone ship Of Course I Still Love You (OCISLY) – and the relatively gentle reentry and trajectory should mean that the booster can be turned around almost immediately for its next launch. B1059 is thus a prime candidate for reuse on a future NASA mission and could very well support Cargo Dragon’s next space station resupply mission (CRS-20) as early as March 2020.
For a number of reasons, the spacecraft’s recent success is a touch bittersweet.
Notably, CRS-19 is the second to last orbital mission scheduled for SpaceX’s original Dragon spacecraft, which debuted in orbit in December 2010, becoming the first commercial spacecraft to successfully reenter and be recovered intact. Less than a year and a half later, Cargo Dragon became the world’s first commercial spacecraft to successful rendezvous and berth with the International Space Station (ISS).
The rest, as they say, is history. Five months later, SpaceX launched Cargo Dragon’s first official mission under NASA’s Commercial Resupply Services (CRS) program, known as CRS-1. Aside from a June 2015 launch vehicle failure that prevented Cargo Dragon from reaching orbit on its CRS-7 mission, SpaceX has successfully completed every resupply mission that managed to reach orbit, delivering more than 43 metric tons (95,000 lb) of supplies to the space station and the astronauts aboard it.
There have been several technical challenges over the years but every Cargo Dragon that reached orbit successfully completed its space station resupply mission and was recovered intact from the ocean surface after reentering Earth’s atmosphere. SpaceX has matured and improved almost every aspect of the spacecraft over the nine years it’s been flying, substantially upgrading its PICA-X heat shield, improving navigation sensors, upgrading its reusability, testing Crew Dragon and Starship hardware, and more.
Cargo Dragon has without a doubt been one of SpaceX’s biggest successes, combining with the company’s exceptionally capable and affordable Falcon 9 rocket to enable reliable cargo resupply missions, while also continuing to be the only way that NASA (or anyone alse) can return substantial non-human payloads back to Earth. Thankfully, although the spacecraft’s exceptional track record is set to come to an end after its next launch, the Cargo Dragon lineage will continue to supply the space station in the form of a modified version of Crew Dragon (i.e. Dragon 2).
On December 26th, SpaceX’s CRS-19 Cargo Dragon – attached to the International Space Station (ISS) – was photobombed by the shadow produced on Earth’s surface by an annular solar eclipse. With any luck, the spacecraft’s first upgraded successor will take over and begin orbital resupply launches as early as August 2020, setting SpaceX up for at least another four or so years of Dragon launches.

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.
