Why is China’s heavy-lift Long March 5B able to release just 10 Guowang satellites at a time?
Using their orange launch and reentry spacesuits, Artemis II leader Reid Wiseman (bottom) and pilot Victor Glover (leading) go out of an emergency situation egress basket throughout nighttime training at Launch Complex 39B.
Invite to Edition 8.06 of the Rocket Report! 2 of the world’s most storied rocket contractors not called SpaceX accomplished significant successes today. Arianespace’s Ariane 6 rocket introduced from French Guiana on its 3rd flight Tuesday night with a European weather condition satellite. Less than 20 minutes later on, United Launch Alliance’s 3rd Vulcan rocket took off from Florida on a United States military objective. These are 2 of the 3 huge rockets established in the Western world that have actually made their orbital launchings in the last 2 years, together with Blue Origin’s New Glenn launcher. Ariane 6 directly won the “race” to reach its 3rd orbital flight, however if you take a look at it another method, Ariane 6 reached its 3rd flight turning point 13 months after its inaugural launch. It took Vulcan more than 19 months, and New Glenn has actually flown simply as soon as. SpaceX’s Super Heavy/Starship rocket has actually flown 9 times however has yet to reach orbit.
As constantly, we invite reader submissions.

Each report will consist of info on little-, medium-, and heavy-lift rockets, along with a glimpse ahead at the next 3 launches on the calendar.
Sixth success for sea-launched Chinese rocket. Personal Chinese satellite operator Geespace included 11 spacecraft to its broadening Internet of Things constellation on August 8, intending to improve low-power connection in essential emerging markets, Space News reports. The 11 satellites rode into orbit aboard a solid-fueled Jielong 3(Smart Dragon 3 )rocket lifting off from an ocean platform in the Yellow Sea off the coast of Rizhao, a city in eastern China’s Shandong province. This was the 6th flight of the Jielong 3, a rocket established by a commercially oriented spinoff of the state-owned China Academy of Launch Vehicle Technology.
Incorrect for a meteor … The 4th phase of the Jielong 3 rocket, left in orbit after releasing its 11 satellite payloads, reentered the environment late Sunday night. The intense and devastating reentry produced a fireball that spotted throughout the skies over Spain, the Spanish paper El Mundo reports. Lots of Spanish locals determined the spotting things as a meteor related to the Perseid meteor shower. It turned out to be a piece of China’s Jielong 3 rocket. Any particles that might have made it through the scorching reentry likely fell under the Mediterranean Sea.

Portugal green-lights Azores spaceport. The Portuguese federal government has actually given the Atlantic Spaceport Consortium a license to develop and run a rocket launch center on the island of Santa Maria in the Azores, European Spaceflight reports. The Atlantic Spaceport Consortium (ASC) was established in 2019 with the objective of establishing an industrial spaceport on Santa Maria, 1,500 kilometers off the Portuguese mainland. In September 2024, the business showcased the island’s viability as a launch website by introducing 2 little solid-fuel amateur-class rockets that it established internal.
What’s on deck? … The spaceport license approved by Portugal’s regulative authorities does not cover specific launches themselves. Those need to be authorized in a different licensing procedure. It’s most likely that the launch website on Santa Maria Island will at first host suborbital launches, consisting of flights by the Polish rocket business SpaceForest. The European Space Agency has actually likewise picked Santa Maria as the landing website for the very first flight of the Space Rider raising body lorry after it releases into orbit, possibly in 2027.

Why is Jeff Bezos purchasing launches from Elon Musk? Early Monday early morning, a Falcon 9 rocket took off from its initial launch website in Florida. Extremely, it was SpaceX’s 100th launch of the year. Maybe a lot more noteworthy was the rocket’s payload: two-dozen Project Kuiper satellites, which were given into low-Earth orbit on target, Ars reports. This was SpaceX’s 2nd launch of satellites for Amazon, which is establishing a constellation to provide low-latency broadband Internet all over the world. SpaceX, then, simply released a direct rival to its Starlink network into orbit. And it was for the creator of Amazon, Jeff Bezos, who owns a rocket business of his own in Blue Origin.
Numerous responses … So how did it concern this– Bezos and Elon Musk, rivals in numerous methods, interacting in area? There are a number of responses. A lot of clearly, releasing payloads for clients is among SpaceX’s 2 core organization locations, along with Starlink. SpaceX offers launch services to all comers and generally provides the most affordable rate per kg to orbit. There’s instant earnings to be made if a business with deep pockets like Amazon wants to pay SpaceX. Second, the other alternatives to get Kuiper satellites into orbit simply aren’t readily available at the volume Amazon requires. Amazon has actually booked the lion’s share of its Kuiper launches with SpaceX’s rivals: United Launch Alliance, Arianespace, and Jeff Bezos’ own area business Blue Origin. SpaceX might get some take advantage of by offering launch services to Amazon. In return for a launch, SpaceX has actually asked other business with telecom satellites, such as OneWeb and Kepler Communications, to share spectrum rights to allow Starlink to broaden into brand-new markets.
Trump orders cull of business launch guidelines. President Donald Trump signed an executive order on Wednesday directing federal government firms to “eliminate or expedite” ecological evaluations for industrial launch and reentry licenses, Ars reports. The FAA, part of the Department of Transportation, is accountable for approving the licenses after guaranteeing launch and reentries do not threaten the general public, abide by ecological laws, and comport with United States nationwide interests. The drive towards deregulation will be welcome news for business like SpaceX, led by one-time Trump ally Elon Musk; SpaceX performs almost all of the industrial launches and reentries certified by the FAA.
Deflecting analysis? … The executive order does numerous things, and not all of them will be as questionable as the prospective removal of ecological evaluations. The order consists of a provision directing the federal government to review, modify, or rescind a slate of launch-safety policies composed throughout the very first Trump administration. The FAA released the brand-new guidelines, called Part 450, in 2020, and they entered into impact in 2021, however area business have actually grumbled that they are too troublesome and have actually decreased the license approval procedure. The Biden administration developed a committee in 2015 to take a look at reforming the guidelines in action to market’s protest. Another part of the order that will likely do not have bipartisan assistance is a require making the head of the FAA’s industrial spaceflight department a political appointee. This task has actually traditionally been held by a profession civil servant.
Ariane 6 launches European weather condition satellite. Europe’s brand-new Ariane 6 rocket effectively introduced for a 3rd time on Tuesday night, bring a satellite into orbit for weather condition forecasting and environment tracking, Euronews reports. “The success of this second commercial launch confirms the performance, reliability, and precision of Ariane 6,” stated Martin Sion, CEO of ArianeGroup, operator of the rocket. “Once again, the new European heavy-lift launcher meets Europe’s needs, ensuring sovereign access to space,” Sion included. It marks the 2nd industrial flight of the rocket, which has actually remained in advancement for nearly a years with the European Space Agency (ESA). It is substantial as it provides Europe independent access to area and lowers its dependence on Elon Musk’s SpaceX.
Eumetsat go back to Europe … The polar-orbiting weather condition satellite released by the Ariane 6 rocket today is owned by the European Organization for the Exploitation of Meteorological Satellites, or Eumetsat. Headquartered in Germany, Eumetsat is an international company that owns and runs geostationary and polar-orbiting weather condition satellites, seeing real-time storm advancement over Europe and Africa, while feeding essential information into international weather condition and environment designs. Simply last month, Eumetsat’s most recent geostationary weather condition satellite introduced from Florida on a SpaceX Falcon 9 rocket since of hold-ups with the Ariane 6 program.
Rocket Lab isn’t providing up on 2025. Rocket Lab continues to promote a very first launch of its medium-lift Neutron rocket before completion of the year, however business executives acknowledge that schedule has no margin for mistake, Space News reports. It might appear not likely, however Rocket Lab’s creator and CEO, Peter Beck, stated in a teleconference with financial investment experts recently that the business has a “green light” schedule to debut the Neutron rocket within the next four-and-a-half months. There’s still much work to do to get ready for the very first launch, and the inaugural flight appears practically particular to slip into 2026.
Release pad almost total … Rocket Lab prepares to host a ribbon-cutting at the Neutron rocket’s brand-new launch pad on Wallops Island, Virginia, on August 28. This launch pad lies simply south of the spaceport’s biggest existing launch center, where Northrop Grumman’s Antares rocket takes off on resupply objectives to the International Space Station. Rocket Lab has a little launch pad for its light-class Electron launcher co-located with the Antares pad at Wallops.
Chinese business exposes drone ship.The Chinese launch business iSpace has actually launched the very first pictures of an ocean-going healing ship to support the landings of recyclable first-stage boosters. The business hosted a commitment event in Yangzhou, China, previously this month for the vessel, which looks comparable to SpaceX’s rocket landing drone ships. In a news release, iSpace stated the ship, called “Interstellar Return,” is China’s very first marine rocket healing ship, and the 5th such vessel on the planet. SpaceX has 3 drone ships in its fleet for the Falcon 9 rocket, and Blue Origin has one for the New Glenn booster.
Rocket agnostic … The healing ship will work with different medium- and large-sized multiple-use rockets, iSpace stated. Its primary usage will be as the landing website for the very first phase booster for iSpace’s own Hyperbola 3 rocket, a medium-lift launcher with methane-fueled engines. The business has actually finished several vertical launch and landing tests of model boosters for the Hyperbola 3. The healing ship determines about 100 meters long and 42 meters large, with a displacement of 17,000 metric heaps, and it has the capability to carry out “intelligent unmanned operations” thanks to a vibrant placing system, according to iSpace.
Vulcan’s very first nationwide security launch. United Launch Alliance provided several United States military satellites into a high-altitude orbit after a prime-time launch Tuesday night, marking a crucial shift from advancement to operations for the business’s brand-new Vulcan rocket, Ars reports. This objective, formally designated USSF-106 by the United States Space Force, was the very first flight of ULA’s Vulcan rocket to bring nationwide security payloads. 2 test flights of the Vulcan rocket in 2015 offered military authorities enough self-confidence to accredit it for releasing the Pentagon’s medium-to-large area objectives.
Secrecy in the fairing …The Vulcan rocket’s Centaur upper phase launched its payloads into geosynchronous orbit more than 22,000 miles (almost 36,000 kilometers) over the equator approximately 7 hours after liftoff. Among the satellites released by the Vulcan rocket is a speculative navigation testbed called NTS-3. It will show brand-new innovations that might be utilized on future GPS navigation satellites. The Space Force decreased to divulge any info about the objective’s other payloads.
Artemis II team trains for nighttime ops.The 4 astronauts training to fly around the Moon on NASA’s Artemis II objective next year have actually been at Kennedy Space Center in Florida today. Among the factors they were at Kennedy was to go through a wedding rehearsal for what it will resemble to operate at the launch pad if the Artemis II objective winds up taking off in the evening. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen placed on their spacesuits and practiced emergency situation treatments at Launch Complex 39B, duplicating a daytime simulation they took part in 2015.
Moving on …The astronauts likewise went inside the Vehicle Assembly Building to practice utilizing egress baskets they would utilize to rapidly get away the launch pad in case of a prelaunch emergency situation. The baskets are secured to the mobile launch tower inside the VAB, where service technicians are putting together and evaluating the Space Launch System rocket for the Artemis II objective. Later on this year, the astronauts will go back to Kennedy for a two-part countdown presentation test. The team members will board their Orion spacecraft once it’s stacked atop the SLS rocket inside the VAB. In part 2, the astronauts will once again practice emergency situation evacuation treatments as soon as the rocket rolls to the launch pad.
China’s Long March 5B flies once again.China is increase building and construction of its nationwide satellite-Internet megaconstellation with the effective implementation of another batch of Guowang satellites by a heavy-lift Long March 5B rocket on Wednesday, Space.com reports. Guowang, whose name equates as “national network,” will be run by China SatNet, a state-run business developed in 2021. The constellation will ultimately include about 13,000 satellites if all goes to strategy.
Make this make good sense … Guowang is a long method from that objective. Wednesday’s launch was the 8th total for the network, however it was the 4th for the job in less than 3 weeks. Each objective lofts simply 5 to 10 Guowang spacecraft, obviously since each satellite is rather big. For contrast, SpaceX releases 24 to 28 satellites on each objective to assemble its Starlink broadband megaconstellation, which presently includes almost 8,100 functional spacecraft. The Long March 5B is China’s most effective functional rocket, with a lift capability rather greater than SpaceX’s Falcon 9 however listed below that of the Falcon Heavy. It pleads the concern of simply how huge the Guowang satellites actually are, and do they have a function beyond broadband Internet service?
