Blue Origin continues SpaceX-competitive rocket R&D with hot-fire engine tests

Published

on

Prospective SpaceX-competitor Blue Origin is continuing research and development work in earnest in an effort to push its first orbital-class rocket, known as New Glenn, closer to the massive vehicle’s launch debut.

In early August, the company shared a video showing a small segment of a long-duration hot-fire test of the rocket engine that will power New Glenn’s second stage, the upper segment of the rocket tasked with placing payloads (typically satellites) into their final orbit(s).

Blue Origin recently announced an intriguing decision to change the upper stage engine its New Glenn rocket will use, moving from a vacuum version of the booster’s massive BE-4 engine (BE-4U) to two updated and modified BE-3 engines, the same propulsion system that powers the company’s much smaller New Shepard suborbital rocket. Rated for roughly 110,000 pounds of thrust (compared to Merlin 1D’s ~190,000 lbf thrust), a duo of the vacuum-optimized engines would be expected to produce roughly the same amount of thrust as SpaceX’s Merlin Vacuum (MVac) upper stage engine.

Before BE-3U took its place, Blue’s original plan was to fly New Glenn as a full-up liquid methane and liquid oxygen (methalox0rocket) on both first and second stages, simplifying the vehicle’s fluid systems and the launch pad’s own ground systems. By replacing BE-4U with BE-3U, the company is instead choosing to make New Glenn’s first stage methalox while the second stage will use liquid hydrogen and oxygen (hydrolox).

 

Blue Origin certainly does have more experience flying hydrolox rockets thanks to its suborbital New Shepard program, and BE-3 is also a mature engine as a result. However, the decision is still difficult to parse. Critically, the company chose to significantly change a fundamental aspect of the rocket engine, moving from a combustion tap-off cycle to an expander cycle, where “cycle” refers to the mechanisms used to pump fuel and oxidizer into a rocket engine’s combustion chamber.

Changing cycles is a fairly dramatic revision and consequently diminishes the value of what might be called “flight-heritage” hardware, or rocket components that have been extensively tested and proven during actual flight operations. Noting one of the main points Blue Origin itself has made in the past and on its own website, it should come as no surprise that New Glenn’s launch debut is believed to have slipped from 2020 into 2021 or even 2022, originally reported by Reuters earlier this month.

“With extensive testing and use on New Shepard and the BE-3, the BE-3U will be one of the best-understood rocket engines before it ever launches into space [on New Glenn].” – Blue Origin

New Glenn’s debut delays will likely push Blue Origin’s first lunar Blue Moon landings beyond the original 2023 launch target. Regardless, a considerable amount of work thus lays before Blue Origin before they will be ready to seriously compete with the likes of SpaceX, Arianespace, and ULA on the global launch market.

Tesla robotaxi test details shared in recent report: 300 operators, safety tests, and more

Tesla has launched an initial robotaxi service for its employees in Austin and the San Francisco Bay Area.

During the Q1 2025 earnings call, Tesla executives reiterated the idea that the company will be launching a dedicated robotaxi service using its Full Self Driving (FSD) Unsupervised system this coming June.

A recent report from Insider, citing people reportedly familiar with the matter, has now provided a number of details about the preparations that Tesla has been making as it approaches its June target date.

Remote Operators

As noted by the publication, about 300 test operators have been driving through Austin city streets over the past few months using Teslas equipped with self-driving software. These efforts are reportedly part of “Project Rodeo.” Citing test drivers who are reportedly part of the program, Insider noted that Tesla’s tests involve accumulating critical miles. Test drivers are reportedly assigned to specific test routes, which include “critical” tracks where drivers are encouraged to avoid manual interventions, and “adversarial” tracks, which simulate tricky scenarios.

Tesla has launched an initial robotaxi service for its employees in Austin and the San Francisco Bay Area, though the vehicles only operate in limited areas. The vehicles also use safety drivers for now. However, Tesla has reportedly had discussions about using remote operators as safety drivers when the service goes live for consumers. Some test drivers have been moved into remote operator roles for this purpose, the publication’s sources claimed.

While Tesla is focusing on Austin and San Francisco for now, the company is reportedly also deploying test drivers in other key cities. These include Atlanta, GA, New York, NY, Seattle, WA, and Phoenix, AZ.

Safety Tests

Tesla reportedly held training events with local first responders as part of its preparations for its robotaxi service, Insider claimed, citing documents that it had obtained. As per the publication, Tesla had met with the city’s autonomous vehicle task force, which include members of the Austin Fire Department, back in December.

Back in March, Tesla reportedly participated in about six hours of testing with local first responders, which included members of the fire department and the police, at a close test track. Around 60 drivers and vehicles were reportedly used in the test to simulate real-world traffic scenarios. 

Interestingly enough, a spokesperson from the Austin Police Department stated that Tesla did hold a testing day with emergency responders from Austin, Williamson County, as well as the Texas Department of Public Safety.

Reported Deadlines

While Tesla has been pretty open about its robotaxi service launching in Austin this June, the company is reportedly pursuing an aggressive June 1 deadline, at least internally. During meetings with Elon Musk, VP of AI software Ashok Elluswamy’s team reportedly informed the CEO that the company is on track to hit its internal deadline.

One of Insider’s sources, however, noted that the June 1 deadline is more aspirational or motivational. “A June 1 deadline makes a June 30 launch more likely,” the publication’s source noted.

Atty who refused to charge six-time Tesla vandal sparks controversy

Despite the multiple offenses, Moriarty opted to enter Adams into an adult diversion program instead.

Hennepin County Attorney Mary Moriarty, who made the decision not to charge 33-year-old vandal Dylan Bryan Adams after he keyed six Teslas around Minneapolis last month, has found herself in the middle of controversy

The controversy came amidst her decision to press charges against a 19-year-old first-time vandal who keyed one vehicle at the White Castle in Brooklyn Park.

The Tesla Vandal

Moriarty’s decision not to charge Adams after he keyed six Teslas was met with widespread criticism. Adams’ actions resulted in more than $20,000 worth of damages, more than $10,000 of which was to a single vehicle, as noted in a New York Post report. Yet despite the multiple offenses, Moriarty opted to enter Adams into an adult diversion program instead.

The fact that Adams is a state employee who works for the Department of Human Services as a program consultant triggered allegations that his dismissal might be partly influenced by Gov. Tim Walz. Walz is a staunch critic of Musk, previously stating that the falling price of TSLA stock gives him a “boost” in the morning.

As noted in a report from The Minnesota Star Tribune, Moriarty’s decision was so controversial that she was asked about the matter on Wednesday. In response, the attorney argued that her office made the decision outside of any political consideration. “We try to make decisions without really looking at the political consequences. Can we always predict how a story will be portrayed in the media or what people will say? No,” Moriarty stated.

Actually Charged

As noted by the Tribune, Moriarty has made arguments around the fact that Adams was a first-time offender, even if he opted to deface six separate Teslas. But even this argument has become controversial since Moriarty recently charged a 19-year-old Robbinsdale woman with no criminal record with first-degree felony property damage after she allegedly keyed a co-worker’s car. The damage incurred by the 19-year-old woman was $7,000, substantially less than the over $20,000 damage that Adams’ actions have caused.

Cases surrounding felony first-degree property damage are fairly common, though they require the damage to be over $1,000. The 19-year-old’s damage to her co-worker’s car met this threshold. Adams’ damage to the six Teslas he vandalized also met this requirement.

When Moriarty was asked about her seemingly conflicting decisions, she noted that her office’s primary goal was to hold the person accountable for keying the vehicle and get restitution to the people affected. She also noted that her office tries to avoid convictions when possible since they could affect a person’s life. “Should we have treated this gentleman differently because it’s a political issue? We made this decision because it is in the best interest of public safety,” she noted.

Tesla faces emission credits tax in Washington state

House Bill 2077 taxes emissions credits, mainly hitting Tesla. Lawmakers expect $100M/year from the taxes.

Washington state lawmakers are advancing a bill that would tax Tesla’s emission credits, targeting profits under the state’s clean vehicle policy. Lawmakers who support the bill clarify that the Tesla credit tax is unrelated to Elon Musk.

HB 2077, introduced in mid-April, seeks to impose a 2% tax on emission credit sales and a 10% tax on banked credits. The bill primarily affects Tesla due to exemptions for companies with fewer credits.

In 2022, Washington’s Department of Ecology mandated that all new cars sold by 2035 be electric, hydrogen-fueled, or hybrids, with 35% compliance required by next year. Carmakers selling more gas-powered vehicles can buy credits from companies like Tesla, which sells only electric vehicles.

A legislative fiscal analysis projects taxes on those credits would generate $78 million in the 2025-27 biennium and $100 million annually thereafter. About 70% of the taxes will be allocated to the state’s general funds, and the rest will help expand electric car infrastructure.

HB 2077 passed the state House eight days after its introduction and awaits a Senate Ways and Means Committee vote on Friday. At a House Finance Committee hearing, supporters, including union and social service advocates, argued the tax would prevent cuts to state services.

House Majority Leader Joe Fitzgibbon emphasized its necessity amid frozen federal EV infrastructure funds. “We didn’t have a budget crisis until this year. And we didn’t have the federal government revoking huge amounts of federal dollars for EV infrastructure,” he said.

Tesla’s lobbyist, Jeff Gombosky, countered that the proposal “runs counter to the intent” of the state’s zero-emission policy. Rivian’s lobbyist, Troy Nichols, noted a “modest” impact on his company but warned it could undermine the EV mandate. Kate White Tudor of the Natural Resources Defense Council expressed concerns, stating, “We worry it sets a dubious precedent.”

Fitzgibbon defended the tax, noting Tesla’s dominant credit stockpile makes it “one outlier” that is “very profitable.” “That’s the kind of thing legislators take an interest in,” he said. “Is it serving the interest of the public for this asset to be untaxed?”

With the legislative session nearing its end, the bill remains a key focus in budget talks in Washington.
