SpaceX’s Falcon 9 rideshare program secures its first customer
On August 22nd, spaceflight startup Momentus Space and launch heavyweight SpaceX announced the first public launch contract to fall under the umbrella of the latter company’s recently-announced Satellite Rideshare Program.
Meant to provide a reliable, consistent, and affordable form of shuttle-like access to orbit, SpaceX’s rideshare program will – pending demand – involve no less than one dedicated Falcon 9 launch per year, capable of placing 15+ metric tons (33,000+ lbs) into low Earth orbit. Although SpaceX’s rideshare proposal is far from revolutionary, the company’s contract with Momentus Space appears to be more than a basic launch service agreement, potentially opening doors for far more flexible rideshare launches in the future.
Since its November 2017 founding, Momentus Space has been able to put money where its mouth is far more so than any comparable space tug hopeful, of which there are several. The concept that has helped Momentus raise nearly $34M in just 1.5 years is relatively simple: build a spacecraft whose sole purpose is to propel other spacecraft to their final orbit(s).
Known as a space tug, the concept is about as old as practical spaceflight itself, and interest in actually developing the concept from paper to hardware has grown exponentially in the last 5-10 years, thanks in large part to an unprecedented boom in commercial spaceflight activity. Applied more specifically, modern efforts like Momentus tend to have ambitious goals couched behind much more achievable (and marketable) concepts.
Momentus Space’s first goal is to bridge the gap between the low cost of smallsat rideshare missions on large rockets and the convenience of smallsat launches on much smaller rockets by building lightweight, simple, and cheap orbital tugs. The first tug the company wants to field is called Vigoride and will measure approximately 2ft x 2ft (0.4m²) and weigh just 80 kg (175 lb) fully fueled. If launched to a 600 km (370 mi) sun-synchronous orbit (SSO), Vigoride will be able to deliver as much as 220 kg (~500 lb) to a final circular orbit of ~1500 km (930 mi) or place 250 kg (550 lb) of satellites into 10+ separate orbits.
Water plasma rockets (!?)
By far the most innovative and potentially revolutionary aspect of Momentus’ plans is its custom propulsion system of choice: water plasma rockets. In simple terms, Momentus space tugs would quite literally turn water and sunlight into a method of in-space propulsion that can offer both moderate efficiency and relatively high thrust. Using solar arrays, the space tug would charge batteries that would then power an extremely high-power microwave electrothermal thruster (MET).
In the case of Momentus, the exotic form of propulsion uses microwaves to almost instantaneously turn liquid water into plasma, an ionized, electrically-charged gas that can then be directed with a magnetic nozzle to produce thrust. Aside from the decent performance it offers, water-based MET allows a given satellite to completely avoid heavy pressure vessels, doesn’t require extremely high voltages, and uses a fully non-toxic propellant (water).
The fact that pure water is so incredibly benign, non-toxic, and accessible opens up a realm of possibilities. Momentus already has plans to launch Vigorides from the International Space Station, and that could eventually expand into actual in-space reuse in which water-powered satellites might dock with the ISS to load more water and pick up new payloads.
In the case of SpaceX, it appears that the company has inked a more two-way agreement with Momentus, in the sense that prospective customers of SpaceX’s Satellite Rideshare Program might actually be able to arrange for their satellites to be included on Vigoride. Vigoride would then be able to deliver each payload – up to 250 kg worth – to its own orbit, potentially far more convenient than simply being kicked off at a lone orbital bus stop. As Momentus matures its technology and moves from Vigoride to Vigoride Extended and beyond, a partnership with SpaceX’s Satellite Rideshare Program could grow into an almost unbeatable turnkey option for the smallsat industry.
Momentus took its first major step towards building capable and marketable space tugs in July 2019 when the company launched X1, its first orbit-worthy satellite prototype. Although the company has been dead silent as to the actual status of that prototype, even a failure would still serve as an invaluable learning opportunity, even if it would be an inconvenient setback. Vigoride’s first test flight was planned as early as late 2019, although the status of that schedule is uncertain.

SpaceX Starship Flight 13 aborted at Zero and Musk just told us what broke
Four Raptor engines failed to ignite at T-zero, forcing SpaceX to scrub Starship Flight 13 Thursday.
SpaceX scrubbed the Starship Flight 13 launch attempt Thursday evening at the last possible moment, after four of the Super Heavy booster’s 33 Raptor 3 engines failed to ignite during the startup sequence. The 90-minute window had opened at 6:45 p.m. EDT from Starbase in Boca Chica, Texas, and the countdown had proceeded without issue all day, with more than 11.5 million pounds of liquid methane and liquid oxygen being fully loaded into the rocket before the automated abort triggered. SpaceX’s launch directors posted on X, “Standing down from today’s flight test attempt,” and shut down the livestream shortly after.
Musk confirmed the root cause within hours. “Some of the engines didn’t start, triggering an automatic launch abort,” he wrote on X. “To be confident of a good flight, 2 Raptors will be removed and replaced. Most probable launch timing is early next week.” SpaceX engineers began draining propellant tanks immediately and Booster 20 was rolled back to its hangar for inspection.
The timing adds a layer of significance that did not exist during any of the previous 12 Starship flights. This is the first time SpaceX has attempted to launch Starship since the company made its stock market debut in June, listing under ticker SPCX at $135 per share. Public investors are now watching every Starship outcome in real time, and a last-second abort carries more visibility than it would have six months ago.
Flight 13 was designed to be one of the most consequential tests in the program’s history. It was set to carry 20 Starlink V3 satellites, the first operational payload Starship has ever attempted to deploy. Six of those satellites carried external cameras to photograph Starship’s heat shield from the outside during flight, which would act as a self-inspection approach SpaceX has never attempted before. The mission also needed to complete a Raptor engine relight in space, a step SpaceX skipped on Flight 12 in May after losing an engine during ascent. That Flight 12 booster also flipped 90 degrees off course during its boostback burn when five engines failed to reignite.
SpaceX has not announced an official next launch date. Musk’s “early next week” window points to July 21 or 22 at the earliest, pending the engine swap and a return to the pad.
Elon Musk flew under the radar with his recent purchase of a $1 billion energy company, according to Federal Trade Commission (FTC) documents.
Transaction number 202612350 listed Tesla and SpaceX frontman Elon Musk as the acquiring party and CF APR Super Holdings LLC as the seller, with New APR Energy, LLC as the acquired entity. The deal, which closed without public announcement, came to light on May 14.

Analysts inferred the deal’s scale from minority stakeholder disclosures, including one report of a 5 percent interest sold for approximately $50.4 million. Fortress Investment Group had purchased APR’s assets in late 2024, rebranded the operation as New APR Energy, and subsequently transferred ownership to Musk.
APR Energy specializes in rapidly deployable power infrastructure. The company maintains one of the world’s largest fleets of mobile gas and diesel turbines, with more than 1.1 gigawatts of generation capacity. Its modular units, which are often trailer-mounted, enable turnkey installations ranging from 20 MW to over 500 MW.
APR provides full engineering, procurement, construction, operation, and maintenance services for behind-the-meter power plants, serving everything from data centers, utilities, and industrial clients.
The firm has expanded aggressively to meet surging demand, recently adding turbines and deploying over 100 MW for a major AI hyperscaler. Its solutions bridge critical gaps where grid interconnections face delays of two to five years, according to Yahoo.
The acquisition means something more for Musk. As he continues to expand projects in artificial intelligence, especially xAI, his AI venture, there is a greater need to supply energy-intensive supercomputing clusters, including the Colossus project, with what they need: reliable and high-capacity power.
Ownership of APR provides immediate access to flexible generation assets that can be deployed adjacent to data centers, reducing dependence on a strained infrastructure. It also complements Tesla’s energy storage business, so Musk will be able to pull from his own entities to address the rapid scaling demands of AI training and compute.
Tesla had a petition protesting a recall to fix a potential issue with 2017-2023 Model Y and Model 3 vehicles’ headlights was denied, as the National Highway Traffic Safety Administration (NHTSA) disagreed with the company’s opinion of things.
The recall covers approximately 19,917 Model Y and Model 3 vehicles built from 2017 to 2023. Tesla initially submitted a noncompliance report for the headlights on these vehicles on March 15, 2024. Tesla then petitioned for an exemption from the fix, which violated FMVSS No. 108 (40 CFR 571.108), arguing that the “noncompliance is inconsequential as it relates to motor vehicle safety.

The NHTSA disagreed, stating that Tesla’s conclusion that the headlights do not increase any risk was not an opinion it shared. The agency said it disagreed with Tesla’s assumption that glare is not increased to surrounding traffic. This issue could be highlighted even more in certain weather conditions.
Tesla will be required to remedy the issue, the NHTSA ruled:
“In consideration of the foregoing, NHTSA has decided that Tesla has not met its burden of persuasion that the subject FMVSS No. 108 noncompliance is inconsequential to motor vehicle safety. Accordingly, Tesla’s petition is hereby denied, and Tesla is consequently obligated to provide notification of and free remedy for that noncompliance under 49 U.S.C. 30118 and 30120.”
The issue here appears to be the angle of the headlights and the brightness they emit during operation. The NHTSA report states that:
“Tesla’s headlamp supplier, Marelli Automotive Lighting, tested 25 right-hand and 25 left-hand lamps, and for this sample, found the maximum photometric intensity measured in the 10°U to 90°U and 90°L to 90°R zone was between 136.2 cd and 230.1 cd for the right-hand lamps and between 117.5 cd and 160.3 cd for the left-hand lamps. According to Tesla, these tests revealed that the photometric intensity of the right-hand and left-hand headlamp lower beam on the subject vehicles may measure as much as 230.1 cd in the 10°U to 90°U and 90°L to 90°R zone, exceeding the maximum photometric intensity by 105.1 cd. Additionally, Tesla states that a left-hand lamp tested by a Transport Canada recognized laboratory measured a maximum of 171.27 cd in the 10°U to 90°U and 90°L to 90°R zone. Despite these measurements exceeding the allowed photometric maximum of 125 cd, Tesla believes that the subject noncompliance is inconsequential to motor vehicle safety.”
Tesla also argued at some points that the headlights had not been deemed responsible for any complaints, accidents, or injuries related to the noncompliance.
