SpaceX’s flight-proven Falcon 9 snags NASA launch contract, second of 2019
NASA has announced that SpaceX’s Falcon 9 rocket – using a flight-proven booster – will launch the ~300 kg (670 lb) Imaging X-ray Polarimetry Explorer (IXPE) spacecraft no earlier than April 2021.
Intriguingly, IXPE was originally planned to launch on Orbital ATK (now Northrop Grumman’s) Pegasus XL but NASA never followed through with a launch contract. The move to SpaceX’s Falcon 9 rocket is likely related to the extremely disruptive and expensive launch delays NASA’s Ionospheric Connection Explorer (ICON) spacecraft has suffered at the hands of its Pegasus XL rocket. Capable of launching less than 450 kg (1000 lb) to low Earth orbit, Pegasus XL has been lucky to launch annually over the last decade or so and carries a price tag of no less than $50M-$60M today.
To add to this: NASA says SpaceX can use a previously flown booster on this mission.
IXPE is a small satellite, but this launch contract is less than what NASA paid for for the still-pending Pegasus XL launch of ICON ($56.3M in a 2014 contract). Think about that… https://t.co/sJlWVMHC5c— Jeff Foust (@jeff_foust) July 8, 2019
Small rocket, huge delays
Defying its small size, Pegasus XL was originally scheduled to launch ICON in December 2017. Delayed by unspecified problems with launch vehicle hardware, the mission was pushed back an inexplicable 10 months to October 2018, where additional issues with the rocket again indefinitely scrubbed a launch attempt. In early 2019, the launch was tentatively scheduled for Q2 2019, while – as of July – ICON is not expected to launch before September 2019.
All said and done, in the increasingly unlikely event that Pegasus XL is ready for launch this September, the ICON spacecraft – ready for launch since late-2017 – will have been delayed more than 21 months by problems with the rocket.
Again, for the small-scale performance of Pegasus XL, the rocket still carries a price tag of more than $50M – NASA’s ICON launch contract was valued at more than $56M. Conscious of this, SpaceX has managed to sway NASA to launch the small IXPE spacecraft on a flight-proven Falcon 9 at a cost of just $50.3 million, easily the lowest Falcon 9 launch contract cost ever publicized.
In recent months, SpaceX executives have made comments indicating that Falcon 9’s default base price – likely assuming a flight-proven booster – is now as low as $50M. July 8th’s NASA launch contract is the first direct confirmation of that exceptionally affordable pricing, likely also indicating that the base price for Falcon 9 is even lower for commercial customers with less stringent requirements.
Barring an unexpected contract between now and IXPE’s expected April 2021 launch, the mission will probably be the first time that a dedicated flight-proven SpaceX rocket launches a scientific spacecraft for NASA. SpaceX’s next dedicated NASA launch – the ESA-built Sentinel 6A spacecraft – is scheduled to no earlier than November 2020 and is likely to fly on a new Falcon 9 booster.
In April 2019, NASA awarded SpaceX $69M for Falcon 9 to launch the agency’s Double Asteroid Redirect Test (DART) – an asteroid-impactor spacecraft – no earlier than June 2021. IXME is SpaceX’s second NASA launch contract win of 2019.
According to NASA, “IXPE will fly three space telescopes with sensitive detectors capable of measuring the polarization of cosmic X-rays, allowing scientists to answer fundamental questions about these turbulent environments where gravitational, electric and magnetic fields are at their limits.”

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.
