SpaceX has now launched a flight-proven Dragon capsule to the International Space Station (ISS) 20 times.

Following the successful launch and docking of the CRS-28 mission. SpaceX broke a couple of U.S. Spaceflight records.

CRS-28 marked the 38th time a Dragon spacecraft visited the orbiting outpost, beating the record held by the Space Shuttle. SpaceX is currently the only U.S.-based company making regular visits to the ISS, with resupply missions and crewed missions for NASA. Later this year, they will also be launching 3 Cygnus resupply vehicles owned by Northrup Grumman, which is retiring its rocket, the Antares 230+.

After the first full day in space, Dragon 2 also broke the U.S. record for total time in space at 1,324 days in orbit. The Dragon capsule that is flying the CRS-28 mission is C208 and is on its 4th flight to the ISS.

Dragon C208 docked with the ISS on Tuesday, June 6th at 5:54 AM ET, delivering over 7000 lbs of supplies and experiments. Also on board, located in the trunk of the spacecraft, is a pair of IROSAs (International Space Station Roll Out Solar Arrays) that will provide increased power to the space station.

Launching this mission was Falcon 9 B1077, which has launched 5 times now, including previously sending the Crew-5 mission to the ISS. After stage separation, the first stage successfully landed on the droneship ‘A Shortfall of Gravitas,’ and while the first stage was landing, the 2nd stage continued its burn to insert the Dragon capsule into the necessary orbit so it could catch up to the ISS. The 2nd stage featured a shorted engine bell as the full MVAC engine bell was not needed, and SpaceX has been able to save on material costs when the extra performance is not required.

With the International Space Station expected to be used well into the future, SpaceX will continue delivering supplies and ferrying astronauts to and from the orbiting outpost for many years to come, most likely surpassing quite a few more spaceflight records.

ArcBest has successfully wrapped up a three-week pilot program testing a Class 8 Tesla Semi in over-the-road applications. The trial was conducted through ArcBest’s ABF Freight division, and it covered routes between Reno and Sacramento and regional operations around the Bay Area.

Tesla Semi pilot sees strong performance and positive driver feedback

The Tesla Semi logged 4,494 miles during the pilot, averaging 321 miles per day with an energy efficiency of 1.55 kWh per mile. The Tesla Semi handled varied terrain, including a 7,200-foot climb over Donner Pass, and delivered performance comparable to diesel counterparts. 

Drivers who participated in the pilot also gave positive feedback to the Tesla Semi, citing the Class 8 all-electric truck’s comfort, safety, and visibility thanks to features like a center seating position and intuitive controls. Matt Godfrey, president of ABF Freight, shared his thoughts on the pilot in a press release

“We’re not looking for a truck that performs well ‘for an EV.’ It must meet or exceed the performance and total cost of ownership targets of our most efficient diesel units. This pilot gives us great insight into the potential of EV semis in our operations,” he said. 

ArcBest highlights need for more charging infrastructure

While the pilot met expectations, ArcBest noted that broader deployment of Class 8 all-electric trucks like the Tesla Semi will still depend on improvements in charging infrastructure. This way, longer-haul operations become more than feasible.

The pilot marks another step in ArcBest’s investment in sustainable logistics technologies. In addition to testing the Tesla Semi, the company operates a small fleet of EVs, including nine electric yard tractors, two electric forklifts, and two Class 6 electric straight trucks. Dennis Anderson, ArcBest chief innovation officer, noted that vehicles like the Tesla Semi are notable developments in the transportation sector.

“Freight transportation is a vital part of the global economy, and we know it also plays a significant role in overall greenhouse gas emissions. While the path to decarbonization presents complex challenges — such as infrastructure needs and alternative fuel development — it also opens the door to innovation. Vehicles like the Tesla Semi highlight the progress being made and expand the boundaries of what’s possible as we work toward a more sustainable future for freight,” he stated.

Tesla could save $2.5B by replacing 10% of staff with Optimus: Morgan Stanley

Tesla’s (NASDAQ:TSLA) near-term outlook may be clouded by political controversies and regulatory headwinds, but Morgan Stanley analyst Adam Jonas sees a glimmer of opportunity for the electric vehicle maker. 

In a new note, the Morgan Stanley analyst estimated that Tesla could save $2.5 billion by replacing just 10% of its workforce with its Optimus robots, assigning each robot a net present value (NPV) of $200,000.

Morgan Stanley highlights Optimus’ savings potential

Jonas highlighted the potential savings on Tesla’s workforce of 125,665 employees in his note, suggesting that the utilization of Optimus robots could significantly reduce labor costs. The analyst’s note arrived shortly after Tesla reported Q2 2025 deliveries of 384,122 vehicles, which came close to Morgan Stanley’s estimate and slightly under the consensus of 385,086.

“Tesla has 125,665 employees worldwide (year-end 2024). On our calculations, a 10% substitution to humanoid at approximately ($200k NPV/humanoid) could be worth approximately $2.5bn,” Jonas wrote, as noted by Street Insider.

Jonas also issued some caution on Tesla Energy, whose battery storage deployments were flat year over year at 9.6 GWh. Morgan Stanley had expected Tesla Energy to post battery storage deployments of 14 GWh in the second quarter.

Musk’s political ambitions

The backdrop to Jonas’ note included Elon Musk’s involvement in U.S. politics. The Tesla CEO recently floated the idea of launching a new political party, following a poll on X that showed support for the idea. Though a widely circulated FEC filing was labeled false by Musk, the CEO does seem intent on establishing a third political party in the United States. 

Jonas cautioned that Musk’s political efforts could divert attention and resources from Tesla’s core operations, adding near-term pressure on TSLA stock. “We believe investors should be prepared for further devotion of resources (financial, time/attention) in the direction of Mr. Musk’s political priorities which may add further near-term pressure to TSLA shares,” Jonas stated.

X CEO Linda Yaccarino has announced that she is stepping down as the social media platform’s chief executive. She shared her update in a post on X.

In her post, Yaccarino highlighted the work that the X team has done over the past two years under her leadership. As per the executive, the company has made significant strides towards its goal of becoming the Everything App. She also highlighted the company’s work in prioritizing the safety of its users, particularly children.

Following is Yaccarino’s statement:

After two incredible years, I’ve decided to step down as CEO of 𝕏. 

When @elonmusk and I first spoke of his vision for X, I knew it would be the opportunity of a lifetime to carry out the extraordinary mission of this company. I’m immensely grateful to him for entrusting me with the responsibility of protecting free speech, turning the company around, and transforming X into the Everything App.

I’m incredibly proud of the X team – the historic business turn around we have accomplished together has been nothing short of remarkable. 

We started with the critical early work necessary to prioritize the safety of our users—especially children, and to restore advertiser confidence. This team has worked relentlessly from groundbreaking innovations like Community Notes, and, soon, X Money to bringing the most iconic voices and content to the platform. Now, the best is yet to come as X enters a new chapter with @xai

X is truly a digital town square for all voices and the world’s most powerful culture signal. We couldn’t have achieved that without the support of our users, business partners, and the most innovative team in the world. 

I’ll be cheering you all on as you continue to change the world. 

As always, I’ll see you on 𝕏.

Elon Musk has issued a response to Yaccarino’s decision to step down as X’s CEO. In a reply, Musk thanked the executive for her work on the social media platform for the past two years. 

“Thank you for your contributions,” Musk wrote.

Under Yaccarino’s leadership, X traversed rocky waters and reestablished itself as a town square where the world’s most notable people are within reach of everyday users across the globe. She also helped lead the company through its acquisition by Elon Musk’s artificial intelligence startup, xAI. At the time, the deal valued X at $33 billion, lower than the $44 billion paid by Elon Musk for Twitter but notably higher than estimates from firms like Fidelity, which valued the social media platform at below $10 billion in late 2024.
