Live to launch — Rocket Report: SpaceX reaches ludicrous cadence; ABL explains RS1 failure “This evidence suggests that an unwanted fire spread to our avionics system.”

Eric Berger – Jan 20, 2023 12:00 pm UTC Enlarge / A Falcon 9 rocket launches on Wednesday morning carrying a GPS III satellite into orbit.Trevor Mahlmann reader comments 25 with 0 posters participating Share this story Share on Facebook Share on Twitter Share on Reddit

Welcome to Edition 5.24 of the Rocket Report! I have a blurb about this below, but for me the news of the week is that SpaceX not only launched a Falcon Heavy rocket, but two other Falcon 9 missions on separate coasts as well in just five days. The operational challenges of this are immense and, I think, underappreciated outside of people directly involved in this kind of work.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

ABL updates on RS1 failure. On Wednesday ABL Space Systems provided an update on the January 10 failure of its RS1 launch vehicle. Long story short, the first stage of the vehicle suffered a “complete loss of power” at 10.87 seconds into flight, leading to a simultaneous shutdown of all nine of the vehicle’s main engines. The rocket impacted the ground about 20 meters from the launch site. “Approximately 95 percent of the vehicle total propellant mass was still onboard, creating an energetic explosion and over-pressure wave that caused damage to nearby equipment and facilities,” the company said.

A fire on board the rocket … The company has begun an anomaly investigation. “There is some visual evidence of fire or smoke near the vehicle QD and the engine bay after liftoff,” ABL wrote. “Shortly before the power loss, a handful of sensors began dropping out sequentially. This evidence suggests that an unwanted fire spread to our avionics system, causing a system-wide failure.” The second RS1 rocket is fully assembled and ready for stage testing, but the results of the anomaly investigation will be needed to inform a timeline for that launch. Kudos to ABL for a transparent and detailed update. (submitted by Ken the Bin) Advertisement

European reusable rocket CEO criticizes reuse. In an interview with a French television station, the chief executive of Maia Space described the challenges of reusing small rockets. Yohann Leroy explained that while the company was looking at a two-thirds drop in performance when the launcher was recovered, the model would not reduce the cost of the launcher by a similar amount, European Spaceflight reports. “Paradoxically, implementing reuse on a small launcher has rather the consequence of increasing the costs per kilogram launched,” Leroy said.

Zut alors! … The company is a wholly owned subsidiary of ArianeGroup, which manufactures the Ariane fleet of rockets. Leroy made his comments as Maia Space is opening itself up to third-party investors. The company has about 30 employees now and seeks to develop a small reusable rocket before moving on to larger reusable launch vehicles. Leroy may not be wrong about the economics of small launch reuse, but I’m not sure that’s the best pitchessentially, “Our business is completely unsustainable!”one might make to potential investors.

Stratolaunch completes second captive-carry flight. This week Stratolaunch announced that its super-sized Roc aircraft had completed a second test flight carrying a Talon-A test vehicle. During the six-hour flight, the aircraft reached a maximum altitude of 22,500 feet, and the team collected information about aerodynamic loads prior to the release point of the Talon-A reusable hypersonic vehicle.

Big plane, little vehicle … This was a test version of the small shuttle-like vehicle. A flight data review will determine the next steps on the test timeline. Stratolaunch said that it continues to progress toward a separation test and its first hypersonic flight of Talon-A 1 within the first half of 2023. That will be something to see.

Chinese firms to build African spaceport. Groups based in Hong Kong and Shanghai have reached a memorandum of understanding with the government of Djibouti to build a $1 billion commercial spaceport on the Horn of Africa, Parabolic Arc reports. The Djiboutian Spaceport, which will be constructed in the northern Obock region near the entrance to the Red Sea, would be the first orbital spaceport in Africa. It is thought to comprise an area of 10 square kilometers.

Not without geopolitical implications … According to the report, construction of the spaceport is expected to begin after the parties sign a formal agreement in March. The project is expected to take five years. This will be a development worth following, as it is easy to understand the interest of Chinese companies in launching from a latitude about 10 degrees north of the equator. China’s rivals, however, also have interests in Djibouti. The US Navy operates Camp Lemonnier nearby, which is the only permanent US military base in Africa. France has a large military base in the country as well.

Why repowering wind farms is wind power’s next big thing

Why repowering wind farms is wind power's next big thing

Renewables developer Exus Renewables North America is giving a $200 million upgrade to Somerset County, Pennsylvania’s 139 megawatt (MW) Twin Ridges Wind Farm – here’s why repowering projects like this are the future of the wind industry.

Wind energy repowering is all about breathing new life into older turbines or entire wind farms. By swapping out aging parts like turbines, blades, and nacelles for the latest tech, wind farms can see significant boosts in efficiency, power capacity, and overall lifespan. Other infrastructure and control systems can also get a second life, too.

Adding new components to existing infrastructure and grid connections mean it’s less expensive to extend the life of the wind farm with fewer resources. New components make the turbines less prone to breakdowns which means less maintenance, so there are fewer operational costs. Plus, a wind farm’s debt is usually paid off at around 10 years, and it qualifies for new tax credits and new financing at around that time. Existing wind farms often have power purchase agreements in place, and data companies are increasingly chasing power sources as demand grows.

Repowering Twin Ridges meant keeping all 68 towers and foundations while swapping out the nacelles and blades. Vestas, which has identified the repower market as a huge opportunity and engineered a solution that’s compatible with most turbines, supplied US-made nacelles, hubs, blades, and tower adaptors for the project. (Twin Ridges’ original supplier, RES, is no longer in business.)

Jim Spencer, CEO of Exus Renewables North America, said of Twin Ridges, “This upgrade will increase the power generation by 30%, which is a lot more power going into the grid. Repowering will allow it to use more of its allotted grid capacity since wind farms don’t operate at maximum capacity 100% of the time.”

Unlike a new wind farm, which comes online all at once, a repowered wind farm sees refurbished turbines turned on one at a time since the infrastructure is already in place. Out of its 68 upgraded turbines, Twin Ridges has brought 40 repowered turbines online, and a 41st turbine will soon follow.

Industry estimates suggest that up to 50 GW of US onshore wind capacity will be assessed for repowering in the next few years.

New Honda battery electric lawn mowers will be made in the USA

New Honda battery electric lawn mowers will be made in the USA

Honda is set to introduce a full line of battery electric walk-behind consumer and zero turn electric riding lawnmowers to its US power equipment dealers for 2025.

Gas-powered lawn equipment is horrible for public health — so much so that a single two-strike leaf blower can produce significantly more harmful carbon emissions than a conventional car. That’s why a growing number of cities and states have passed regulations restricting the use of gas-powered lawn equipment.

As our own Jamie Dow put it, “It’s important to mention how horrendous gas lawn equipment is all the time, and how it’s often possible to get electric stuff for cheap because air quality districts know this is some of the lowest hanging fruit. The issue is that ‘small off-road engines‘ (SOREs) usually don’t include any sort of pollution controls, and are often dirtier two-stroke engines that create more power in a small package, but emit orders of magnitude more pollution in the form of unburned particulates from the incomplete combustion process they undergo when compared to four-stroke engines.”

With that in mind, then, we have to consider the recent announcement that Honda will be offering its battery electric HRX, HRN, and HRC walk-behind consumer lawn mowers and a zero-turn-radius (ZTR) commercial electric riding lawn mower at select Honda Power Equipment dealers nationwide in 2025.

That’s bigger news than you might think, too. That’s because Honda actually stopped producing new lawn mowers in 2023 amid tightening emissions regulations amid shifting customer preferences. The new battery-powered lineup will, therefor, re-establish Honda dealers as full-line outdoor power equipment (OPE) stores while, at the same time, supporting the company’s electrification vision.

“With the new line of Honda battery-powered lawn mowers, we will deliver the exceptional ownership experience that our customers have come to expect while providing lawn care options for a variety of users, conditions and applications,” says Mark Kohls, vice president of Honda Power Sports & Products at American Honda. “Reducing greenhouse gas emissions is only part of the challenge, as battery-powered power products must meet Honda standards for rugged performance, ease of use and comfortable operation to meet the high expectations of our residential and commercial customers.”

Honda ZTR electric riding mower

On the commercial front, Honda’s new ZTR mowers are powered by 5 separate, 48V brushless electric motors — 3 motors under the machine’s 60″ cutting deck (12″ wider than the Kubota‘s) that each power a rotating set of twin blades, and 2 drive wheel motors to maneuver the mower with precise control. The company says it’s engineered to, “stand up to the rigors of commercial landscaping, with power to mow at maximum efficiency while maintaining pristine cut quality.”

Honda says the ZTR’s six 48-volt lithium-ion battery packs offer enough power to mow up to 15 acres of lawn on a single charge, and can be recharged in under 6 hours on a 220V outlet.

The new ZTR will be the first electrified power product produced at Honda North Carolina Manufacturing (NCM) facility in Swepsonville, and will be assembled using both “using “domestic and globally sourced parts.”

“Technology is aggressively shaping the future of the world, including the landscaping industry, and trends show that buyers are integrating battery-powered products into their fleets,” said Kohls. “Honda Sports & Products is providing the battery-powered Honda ZTR lawn mower to introduce flexibility into the fleet, help increase operating efficiency and comfort, address labor shortages and support the sustainability goals of commercial landscapers.”

No word, yet, on pricing.

ENGWE’s Class 3 entry-level L20 2.0 e-bike hits $699 in Black Friday sales + bonus savings

ENGWE’s Black Friday sale has kicked into gear through December 2, taking up to $600 off e-bikes and also offering discounted accessories, free gear, and multiple chances to get your order paid back in full (more info below). A notable price cut from previous sales is the entry-level L20 2.0 e-bike that is going for $699 shipped. It’s normally priced at $999 since it was released in March, with the lowest we saw it go being a fall to $659 at the end of summer. Since summer’s end, it’s kept at above $799, most recently during the previous Halloween sale, but that price is getting beaten out today with a total $300 markdown that lands it at the second-lowest price we have tracked – just $50 above the all-time low from summer. Learn more about the sale’s bonus savings and this e-bike below, or you can learn about it in our hands-on review.

For all the orders placed during this sale, ENGWE will have four different drawing periods (Nov 11, 18, 25, and Dec 2) with two winners in each – all of them receiving a full refund on their orders. Along with this, ENGWE is also giving away a free accessory mystery box with every order over $600 that gives you free gear worth up to $109.

One of the newer models coming out of ENGWE, the L20 2.0 e-bike makes for a solid entry-level commuter that will weigh far lighter on your wallet than many other brands. Its 750W geared hub motor provides a 28 MPH top speed when utilizing the pedal assistance, and 20 MPH speeds cruising on pure electric power. The 52V 676Wh battery delivers a range of up to 68 to 80 miles on a single charge (depending on conditions), while only using the throttle cuts that down to around 28 miles, which is still plenty to get you around.

It has a folding frame, making its off-riding storage and transport an easier task, plus is weighs just about 68 pounds making it easy to manage for most folks living in apartment buildings. And for the price, it also comes with some decent additional features, like the mechanical disc brakes on 180 mm rotors, a rear cargo rack, integrated head/tail/brake LED lights, front fork and post suspension, a SHIMANO 7-speed derailleur, puncture-resistant fat tires, and a color LED display.

Xtracycle Stoker cargo e-bike

Save $1,350 on Xtracycle’s Stoker off-road cargo e-bike with free gear at $3,999 in Black Friday sales

Xtracycle has begun its early Black Friday sales through November 18, offering up to $1,350 in savings on three different e-bike bundles. Among the three discounted models here, the prices start lowest for the brand’s Stoker Off-Road Cargo e-bike which is down at $3,999 shipped. This higher-end model normally sits at its $4,499 price tag most of the time, not seeing as many discounts as some of its higher-priced counterparts, though we did see a similar bundle offer back during the brand’s Labor Day sales. This month’s sale is giving us a bigger bundle than previously seen, as the included Everyday Rider Bundle also gives you an everyday bike pack, a 40L cargo bag that attaches to the bike’s frame, a padded cushion for passengers, a Hooptie rail system, and a Snackbar rail system – plus, you’ll also be getting free shipping and local assembly fees waived, giving you a total of $1,350 in savings ($260 more value than Labor Day).

The Xtracycle Stoker e-bike is an all-terrain cargo-hauling model that can traverse streets, trails, and more with ease. A Shimano STEPS EP-8 motor and a 630Wh battery reside within its chromoly steel frame, providing a 20 MPH top speed with its pedal assistance system (without any throttle) for up to 60 miles on a full charge. The terrain isn’t much of a concern thanks to the 24-inch NICA’GNAR Cargo Tires which come with fenders over each, and it has 4-piston hydraulic disc brakes for reliable stopping power the moment it is needed. The entire bike is rated for a total 400-pound payload, coming with an integrated rear cargo rack that only has its capabilities bolstered by the free gear. Among its other features, there’s the Sram NX11 X-HORIZON derailleur, integrated LED headlights and taillights, and an E-series cycling computer that gives you easy handlebar access to controlling your settings as you ride.

Greenworks’ 80V Venture 27.5-inch commuter e-bike hits new $1,520 low

Amazon is offering rare discounts on a pair of Greenworks’ Venture series e-bikes, with the Greenworks 80V Venture 27.5-inch Commuter e-bike for $1,519.99 shipped. Normally going for $1,900 since first releasing at the start of the year, we’ve only seen one previous discount on this model, which dropped costs to $1,615 back in February. It’s been keeping to its MSRP all this time since but is finally seeing its price come down thanks to the 20% markdown here that slashes $380 off the price tag and lands it at a new all-time low. It also beats out Greenworks’ direct site, where it’s still sitting at full price.

This 80V commuter e-bike is one of Greenworks’ new Venture series models, designed to expand the brand’s versatile battery ecosystem, which is standard across most of its tools. The 350W brushless rear hub motor (that peaks at 500W) is powered by the brand’s included 4.0Ah battery (and you’ll also get a rapid charger) that can also be switched out with other tools/batteries you may already own. Utilizing three different forms of pedal assistance as you ride, you’ll be able to cruise around at 20 MPH top speeds for up to 22 miles on a single 40-minute charge. It also features a front suspension fork, an adjustable suspension seat, a 7-speed Shimano shifter, 27.5-inch Kenda tires, an LED headlight, a rear cargo rack, as well as an LCD display paired with a simple control panel along the handlebars.

If you would prefer an electric mountain bike instead, Amazon is also offering the Greenworks 80V Venture 26-inch All-Terrain Fat Tire e-bike for $1,280.99 shipped, down from $2,100. This model sports a larger 500W brushless rear hub motor (peaking at 750W) to better support you through off-road travels, providing the same speed and mileage as the above model with its three pedal assist modes. You’re getting the same general features too, aside from the 26-inch by 4-inch all-terrain Kenda fat tires and minus the rear cargo rack.

Best Black Friday e-bike deals!
