SpaceX Cargo Dragon spacecraft arrives at space station on second to last mission
SpaceX’s Cargo Dragon has successfully rendezvoused with the International Space Station (ISS) as part of NASA’s CRS-19 resupply mission, marking what is almost certainly the spacecraft’s second to last orbital launch.
On December 5th, new Falcon 9 booster B1059 lifted off from SpaceX’s LC-40 Cape Canaveral Air Force Station (CCAFS) launch pad with a fresh upper stage and twice flown Cargo Dragon capsule C106 atop it. A little over nine minutes after launch, B1059 prepared to be robotically secured on drone ship Of Course I Still Love You (OCISLY) while Cargo Dragon – now in orbit – separated from Falcon 9’s upper stage and headed on its merry way.
Cargo Dragon’s 20th orbital mission and 19th trip to the ISS, CRS-19’s twice-flown spacecraft commanded the deployment of its two solar arrays, primed its Draco maneuvering thrusters, and opened up its Guidance, Navigation, and Control (GNC) bay. Using star trackers, inertial measurement devices, and lasers, Dragon then proceeded to precisely deliver itself to the ‘door’ of the space station before gradually approaching.
Astronauts aboard the ISS then manually guided Canadarm2 – a massive robotic arm externally attached to the space station – towards Cargo Dragon as it used its thrusters to essentially hover in place, ultimately grabbing the spacecraft with a sort of mechanical hand. At that point, Dragon effectively became a part of the ISS and astronauts monitored the subsequent (and mostly automated) process of using Canadarm2 to fully berth spacecraft with the station.
After berthing, astronauts are able to equalize the pressure between the ISS and visiting spacecraft and open the hatch, gaining access to whatever cargo it was loaded with prior to launch. Alternatively, visiting vehicles can also dock with the International Space Station, a process controlled entirely by the arriving spacecraft, a bit like berthing but with almost all of the risk on its shoulders. All Russian spacecraft currently use this method, as do Boeing’s Starliner and SpaceX’s Crew Dragon.
As it turns out, CRS-19 – partially hinted at in the name – is the second to last launch of SpaceX’s Dragon 1 (Cargo Dragon), which become the first commercial spacecraft capable of reentering Earth’s atmosphere in 2010 and rendezvousing with a space station in 2012. Five months later, SpaceX launched CRS-1 – its first operational resupply mission – and the rest is (more or less) history.
In the seven years since CRS-1, Cargo Dragon – including CRS-19 – has now flown 18 successful space station resupply missions and delivered more than 90,000 lb (50,000 kg) to its ever-changing crew of astronauts. Cargo Dragon has undergone at least two significant upgrades and suffered its fair share of mishaps, but has still successfully completed its mission every time it reached orbit.
NASA’s CRS1 SpaceX contract ultimately called for a total of 20 Cargo Dragon missions to the ISS, although more could technically be added retroactively if both entities were to decide they were needed. Currently, the plan is for CRS-20 – Cargo Dragon’s next launch – to be the spacecraft’s last orbital mission and is scheduled no earlier than March 2020.
After CRS-20, SpaceX – via its subsequent CRS2 NASA contract – means to introduce a version of Crew Dragon (Dragon 2) modified for cargo-only missions, optimally taking flight-proven Crew capsules and reusing them as Cargo Dragon 2s.
SpaceX recently revealed that the first Cargo Dragon 2 spacecraft will unexpectedly not feature Crew Dragon’s complex SuperDraco abort system, a feature that has recently created several roadblocks. However, this dramatically simplifies Dragon 2 and means that SpaceX is still quite confident that the upgraded cargo spacecraft will be ready for its launch debut next year.
Known as CRS-21, that mission will see SpaceX’s CRS launches move from LC-40 to Kennedy Space Center’s LC-39A pad in order to enable extremely late and convenient cargo-loading via Pad 39A’s Crew Access Arm (CAA), to be primarily used by astronauts boarding Crew Dragon. Similarly, Cargo Dragon 2 will dock with the ISS instead of using Dragon’s current berthing route, nominally requiring less hands-on astronaut time for each resupply mission.
Cargo Dragon will be missed but will forever remain a major piece of commercial spaceflight history. Dragon 2 will likely toe the line for the first half of the next decade, but SpaceX ultimately wants to get its generation Starship launch vehicle online as soon as possible – a feat that will make all Falcon and Dragon vehicles redundant if things go as planned.

Tesla Semi expands pilot program to Texas logistics firm: here’s what they said
Mone said the Tesla Semi it put into its fleet for this test recorded 1.64 kWh per mile efficiency, beating Tesla’s official 1.7 kWh per mile target and delivering a massive leap over conventional diesel trucks.
Tesla has expanded its Semi pilot program to a new region, as it has made it to Texas to be tested by logistics from Mone Transport. With the Semi entering production this year, Tesla is getting even more valuable data regarding the vehicle and its efficiency, which will help companies cut expenditures.
Mone Transport operates in Texas and on the Southern border, and it specializes in cross-border U.S.-Mexico freight operations. After completing some rigorous testing, Mone shared public results, which stand out when compared to efficiency metrics offered by diesel vehicles.
“Mone Transport recently had the opportunity to put the Tesla Semi to the test, and we’re thrilled with the results! Over 4,700 miles of operations at 1.64 kWh/mile in our Texas operation. We’re committed to providing zero-emission transportation to our customers!” the company said in a post on X.

Mone said the Tesla Semi it put into its fleet for this test recorded 1.64 kWh per mile efficiency, beating Tesla’s official 1.7 kWh per mile target and delivering a massive leap over conventional diesel trucks.
Comparable Class 8 diesel semis, typically achieving 6-7 miles per gallon, consume roughly 5.5 kWh per mile in energy-equivalent terms, meaning the Semi uses three to four times less energy while also producing zero tailpipe emissions.
Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
The performance of the Tesla Semi in Mone Transport’s testing aligns with data from other participants in the pilot program. ArcBest’s ABF Freight Division logged 4,494 miles over three weeks in 2025, averaging 1.55 kWh per mile across varied routes, including a grueling 7,200-foot Donner Pass climb. The truck “generally matched the performance of its diesel counterparts,” the carrier said.
PepsiCo, which operates the largest known Semi fleet, recorded 1.7 kWh per mile in North American Council for Freight Efficiency testing. Additional pilots showed similar gains: DHL hit 1.72 kWh per mile, and Saia achieved 1.73 kWh per mile.
These metrics underscore the Semi’s ability to slash operating costs through superior efficiency, lower maintenance, and zero-emission operation. As charging infrastructure scales and production ramps toward 2026 targets, participants like Mone Transport are proving electric semis can seamlessly integrate into freight networks, accelerating the industry’s shift to sustainable, high-performance trucking.
Tesla continues to prep for a more widespread presence of the Semi in the coming months as it recently launched the first public Semi Megacharger site in Los Angeles. It is working on building out infrastructure for regional runs on the West Coast initially, with plans to expand this to the other end of the country in the coming years.

SpaceX weighs Nasdaq listing as company explores early index entry: report
The company is reportedly seeking early inclusion in the Nasdaq-100 index.
Elon Musk’s SpaceX is reportedly leaning toward listing its shares on the Nasdaq for a potential initial public offering (IPO) that could become the largest in history.
As per a recent report, the company is reportedly seeking early inclusion in the Nasdaq-100 index. The update was reported by Reuters, citing people familiar with the matter.
According to the publication, SpaceX is considering Nasdaq as the venue for its eventual IPO, though the New York Stock Exchange is also competing for the listing. Neither exchange has reportedly been informed of a final decision.
Reuters has previously reported that SpaceX could pursue an IPO as early as June, though the company’s plans could still change.
One of the publication’s sources also suggested that SpaceX is targeting a valuation of about $1.75 trillion for its IPO. At that level, the company would rank among the largest publicly traded firms in the United States by market capitalization.
Nasdaq has proposed a rule change that could accelerate the inclusion of newly listed megacap companies into the Nasdaq-100 index.
Under the proposed “Fast Entry” rule, a newly listed company could qualify for the index in less than a month if its market capitalization ranks among the top 40 companies already included in the Nasdaq-100.
If SpaceX is successful in achieving its target valuation of $1.75 trillion, it would become the sixth-largest company by market value in the United States, at least based on recent share prices.
Newly listed companies typically have to wait up to a year before becoming eligible for major indexes such as the Nasdaq-100 or S&P 500.
Inclusion in a major index can significantly broaden a company’s shareholder base because many institutional investors purchase shares through index-tracking funds.
According to Reuters, Nasdaq’s proposed fast-track rule is partly intended to attract highly valued private companies such as SpaceX, OpenAI, and Anthropic to list on the exchange.

The Boring Company’s Prufrock-2 emerges after completing new Vegas Loop tunnel
The new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The Boring Company announced that its Prufrock-2 tunnel boring machine (TBM) has completed another Vegas Loop tunnel in Las Vegas. The company shared the update in a post on social media platform X.
According to The Boring Company’s post, the new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The new tunnel marks the fourth tunnel constructed near Westgate Las Vegas as the Vegas Loop network continues expanding across the city.
The Boring Company also noted that the new tunnel surpassed its previous internal record of 2.26 miles for a single Vegas Loop segment.
Construction of the tunnel involved moving roughly 68,000 cubic yards of dirt. The excavation process also used about 4.8 miles of continuous conveyor belt, powered by six motors totaling 825 horsepower.
The Boring Company’s Prufrock-series all-electric tunnel boring machines are designed to support the rapid expansion of company’s underground transportation projects, including the growing Vegas Loop network. Prufrock machines are designed for reusability, thanks in no small part to their capability to be deployed and retrieved easily through their “porposing” feature.
The Vegas Loop, specifically the Las Vegas Convention Center (LVCC) Loop segment, has already been used during major events. Most recently, the LVCC Loop supported the 2026 CONEXPO-CON/AGG construction trade show, which was held from March 3-7, 2026.
As per The Boring Company, the LVCC Loop transported roughly 82,000 passengers across the convention center campus during the event’s duration.
CONEXPO-CON/AGG is one of the largest construction trade shows in North America, drawing more than 140,000 construction professionals from 128 countries this year.
The LVCC Loop forms the initial segment of the broader Vegas Loop network, which remains under active development as The Boring Company continues building new tunnels throughout the city.
