SpaceX Falcon Heavy rocket to launch NASA’s Roman Space Telescope
NASA has chosen SpaceX’s Falcon Heavy rocket to launch its next major space telescope, a wide-field observatory that should directly complement the brand new James Webb Space Telescope.
Originally known as the Wide Field InfraRed Survey Telescope (WFIRST), NASA recently renamed the mission in honor of Nancy Grace Roman, a foundational force behind the Hubble Space Telescope. Fittingly, the Roman Space Telescope’s basic design is reminiscent of Hubble in many ways, owing to the fact that the mission exists solely because the US National Reconnaissance Office (NRO) chose to donate an unused multi-billion-dollar spy satellite – a satellite that was effectively a secret Earth-facing version of Hubble.
However, thanks to decades of improvements in electronics, electromechanics, and the instrumentation side of spacecraft and space telescopes, RST will be dramatically more capable than the Hubble telescope it resembles. And now, after a several-year fight for survival, the Roman Space Telescope officially has a ride to space – SpaceX’s Falcon Heavy rocket.
Falcon Heavy continues to be a bit of a paradox, winning contract after contract for increasingly high-value flagship launches despite having not launched once in more than three years. It’s a bit of a self-fulfilling prophecy, at this point, as the major missions that are increasingly being entrusted to Falcon Heavy are far more likely to run into significant spacecraft-side delays. At one point in late 2021, for example, SpaceX had five Falcon Heavy launches tentatively planned in 2022 – all but one of which had already been delayed several months to a year or more. Seven months into 2022, not one of those missions has launched and it’s looking increasingly likely that Falcon Heavy will be lucky to fly at all this year.
Nonetheless, the Roman Space Telescope joins an impressive manifest that includes the multi-billion-dollar GOES-U weather satellite, NASA’s ~$5 billion Europa Clipper, two modules (HALO and PPE) of a Moon-orbiting space station, NASA’s Psyche asteroid explorer, a large Astrobotic Griffin lander carrying NASA’s VIPER Moon rover, two large geostationary communications satellites, and three missions for the US military. RST is the rocket’s 11th launch contract between now and the mid-2020s.
Despite having a similar resolving power, RST’s primary wide-field instrument will have a field of view 100 times greater than Hubble, meaning that the new telescope will be able to gather magnitudes more data in a similar time. Its primary goals include measuring “light from a billion galaxies over the course of the mission lifetime” and performing “a microlensing survey of the inner Milky Way to find ~2,600 exoplanets.” A second coronagraph instrument will “perform high-contrast imaging and spectroscopy of dozens of individual nearby exoplanets.” According to the Jet Propulsion Laboratory, “the Coronagraph provides a crucial stepping stone in the preparation of future missions aiming to [directly] image and characterize Earth-like planets [that are] 10 billion times fainter than their host star.”
According to NASA, “the telescope’s science program also includes dedicated investigations to tackle outstanding questions [about the nature and] effects of dark energy and dark matter, as well as a substantial general investigator program to enable further studies of astrophysical phenomena to advance other science goals.”
Because RST is also focused on infrared wavelengths of light, it could be an excellent companion to the James Webb Space Telescope (JWST). Whereas RST is a wide-field survey observatory that aims to observe and catalog billions of galaxies, stars, and planets, JWST’s far larger mirror is optimized for up-close observation of individual targets or deep gazes into tiny swaths of sky. RST could ultimately work a bit like an MRI or CAT scan to JWST’s biopsy, telling the surgeon where to look but only hinting at what it might find.
According to NASA, the ~$4.3 billion space telescope’s Falcon Heavy launch contract will cost an exceptionally steep $255 million to send the spacecraft to the Sun-Earth L2 Lagrange point about 800,000 kilometers (~500,000 mi) from Earth. NASA’s contract to launch the even more expensive Europa Clipper spacecraft all the way to Jupiter with a fully-expendable Falcon Heavy rocket is expected to cost less than $180 million.
NASA’s press release also claims that RST will be ready to launch as early as October 2026. A different press release from September 2021 did not mention the 2026 target and only noted that RST’s launch is scheduled no later than May 2027.

Tesla Semi shows strong results in ArcBest’s real-world freight trial
The truck handled varied terrain, including a 7,200-foot climb over Donner Pass.

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
Jonas assigned each robot a net present value (NPV) of $200,000.

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.

Linda Yaccarino steps down as X CEO
Yaccarino highlighted the work that the X team has done over the past two years under her leadership.

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.
