Antares’ final mission was a 100 percent success as the rocket sent the Cygnus cargo spacecraft to the International Space Station.

The launch occurred on time at 8:31 p.m. ET (00:31 UTC) from Launch Pad 0 at the Mid-Atlantic Regional Spaceport on Wallops Island in Virginia. Cygnus will arrive at the International Space Station on August 4th and a planned berthing to the station at 5:55 a.m. ET (09:55 UTC).

Since the first Cygnus mission, all have been named, and for this mission, it has been named the S.S. Laurel Clark in honor of the NASA astronaut who flew on the STS-107 Space Shuttle Columbia mission.

Following orbital insertion, the Cygnus spacecraft had no issues as it unfurled its two solar arrays that will provide power to the spacecraft on its journey to the Space Station. During the NG-18 mission, one of the solar arrays failed to deploy due to debris being lodged into the separation mechanics during stage separation.

Similar to how older SpaceX Dragon cargo capsules were berthed to the ISS, NASA astronaut Woody Hoburg will use the Canadarm2 to grapple Cygnus and attach it to the Space Station. Once Cygnus is attached, the crew aboard the ISS will begin removing the supplies and experiments from the vehicle.

In addition to the supplies, some of the experiments on board include:

Better water for explorers: This system, Exploration PWD, features advances in water sterilization, and microbial growth reduction, and has the ability to dispense hot water.

Testing gene therapy: Neuronix: will demonstrate the formation of three-dimensional neuronal cell cultures in microgravity and tests a neuron-specific gene therapy. If successful, it could provide the opportunity to test drugs and treatments for neurological disease on the ISS.

Astrobee: A free-flying robot that uses electric fans to navigate, will help astronauts with routine daily activities. The Astrobee system consists of 3 robots named Bumble, Honey, and Queen. The system has been in use off and on since 2018.

Cygnus will depart the ISS in October, carrying with it thousands of pounds of trash and one final experiment that will occur before its fiery re-entry into Earth’s atmosphere.

Tesla tops American-Made Index for sixth-consecutive year

Tesla is atop the American-Made Index from Cars.com for the sixth-straight year, as the Model 3 and Model Y took the top two spots, respectively.

Last year, the Model 3, Model Y, Model S, and Model X took the top four spots, respectively. The company has routinely performed well in the Index. However, Tesla discontinued its flagship Model S and Model X earlier this year, which took the two cars out of the ranking.

Cybertruck is not considered due to its curb weight being above the 8,500-pound threshold, which eliminates it from being required to have more detailed assembly information.

Cars.com uses five main categories to develop its rankings:

  • Location(s) of final assembly
  • Percentage of U.S. and Canadian parts
  • Countries of origin for all available engines
  • Countries of origin for all available transmissions
  • U.S. manufacturing workforce

These five major factors are then put into a 100-point scale. The vehicles with the highest scores sit atop the list. The Model 3 edged out the Model Y.

Tesla uses a strong domestic strategy to build its cars and parts domestically. It relies on intense vertical integration that reduces its dependence on global suppliers, keeping more value and jobs in the United States.

This strategy has helped Tesla gain a strong reputation for domestically produced vehicles and parts. However, it helps it with more than just awards like this one. Keeping a supply chain local has also helped insulate Tesla more than others from tariffs and supply chain disruptions.

This year’s American-Made Index from Cars.com studied nearly 400 vehicles from the 2026 model year. Tesla was the only manufacturer to have an EV inside the Top 10. The Kia EV9 was the next EV to make the list, scoring the 17th position.

The Hyundai IONIQ 5 was 21st, and the final EV to make the list was the Cadillac LYRIQ in 77th.

Tesla finally clarifies fatal Texas crash, confirms driver manually overrode acceleration

Tesla has finally clarified the situation regarding the viral crash in Texas where a Model 3 slammed into a home.

CEO Elon Musk replied to reports on Monday that stated the crash was due to the company’s Full Self-Driving or Autopilot suite, which seemed unlikely to those who are familiar with it. Video showed the car slamming into a house at an excessive rate of speed, making it highly unlikely the crash was due to the suite’s operation, as it does not travel at those speeds in residential areas.

Musk said:

“This makes no sense. FSD drives slowly through neighborhood streets, and this was a high-speed crash!”

Tesla’s Head of AI, Ashok Elluswamy, added context, revealing that the company’s data shows the driver “manually overrode self-driving by pressing the accelerator all the way to 100%.”

He revealed the speed reached by the car was 73 MPH, and the accelerator was still pressed “even after the crash.”

Authorities are reportedly investigating “whether Tesla’s Autopilot system played a role after a Model 3 left the roadway…slammed through a brick house at high speed and fatally struck Matha Avila as she sat inside,” the New York Post reported.

The National Highway Traffic Safety Administration (NHTSA) is now investigating the crash. Tesla will work with the agency to provide them with whatever information they need in order to clarify the cause of the crash.

Similarly, Tesla had claims of a fatal accident in Harris County, Texas, a few years ago. Early reports indicated that Full Self-Driving was the cause of the crash. After the National Transportation Safety Board (NTSB) worked with Tesla, the agency proved there was “no use of the Autopilot system at any time during this ownership period of the vehicle, including the time frame up to the last transmitted timestamp on April 17, 2021.”

“Application of the accelerator pedal was found to be as high as 98.8 percent,” the NTSB said in their findings. The highest recorded speed in the five seconds leading up to the impact was 67 miles per hour. The area where the crash occurred is residential, and Texas State laws have default speed limits of 30 MPH in residential streets.

This appears to be a similar situation. However, an investigation will prove what happened for sure.

SpaceX makes $20 billion move to optimize its balance sheet

SpaceX announced today that it commenced its first-ever public bond offering, marking a significant step in the newly public company’s capital markets strategy.

The company announced an offering of senior unsecured notes expected to raise at least $20 billion.

The move comes just a short time after SpaceX completed one of the largest initial public offerings in history. In mid-June, the company priced shares at $135 and raised more than $85 billion, propelling founder Elon Musk’s net worth past the trillion-dollar mark and giving the firm substantial liquidity.

According to the company’s SEC filing, the net proceeds from the notes will be used primarily to repay in full the outstanding borrowings under its existing bridge loan facility, cover related fees and expenses, and fund general corporate purposes. The offering is being conducted under Rule 144A, as well as Regulation S, targeting qualified institutional buyers and non-U.S. investors. Notes will be unsecured obligations ranking equally with other unsubordinated debt.

The $20 billion bridge loan was used to refinance approximately $17.5 billion in higher-cost “junk” debt tied to X and xAI. SpaceX had merged with xAI in February 2026 in an all-stock deal. The bridge facility, which matures in September 2027, had represented the bulk of SpaceX’s long-term debt.

In connection with the bond launch, SpaceX disclosed it held approximately $100.8 billion in cash and cash equivalents as of June 19. Investor calls began on the announcement date, with pricing and launch expected shortly thereafter. Rating agencies have assigned investment-grade ratings to the proposed bonds, reflecting confidence in SpaceX’s dominant position in commercial launches and the growth trajectory of its Starlink internet offering.

The debt raise also allows SpaceX to optimize its balance sheet by replacing short-term, higher-cost bridge financing with longer-date, lower-cost fixed-income securities. This provides greater financial flexibility to support capital-intensive initiatives, including the development of Starship, the expansion of the Starlink constellation, and the integration of AI capabilities following the xAI combination.

SpaceX shares (NASDAQ: SPCX) fell sharply on the news, dropping over 16 percent overall on the market on Monday. The stock had surged initially after debuting but pulled back amid profit-taking and broader market dynamics.

Overall, the bond offering underscores SpaceX’s transition to a mature public company with access to diverse funding sources. It positions the firm to pursue its long-term vision of multiplanetary expansion and AI infrastructure, while maintaining a disciplined approach to its capital structure in a high-growth but capital-heavy industry.
