Two more launches today

3:35 pm

As expected, SpaceX and China completed launches today.

First SpaceX launched another 24 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its 20th flight, landing on a drone ship in the Pacitic.

Next, China placed an unspecified “group” of “remote sensing” satellites into orbit, its Long March 6A rocket lifting off from its Taiyuan spaceport in northeast China. No word on where the rocket’s lower stages crashed inside China.

The leaders in the 2025 launch race:

114 SpaceX
51 China
12 Rocket Lab
11 Russia

SpaceX still leads the rest of the world in successful launches, 114 to 88.

China yesterday completed two launches

9:03 am

China yesterday successfully completed two launches using different rockets from two different spaceports in the country’s interior.

First, its Long March 3C rocket launched a classified technology test satellite, the rocket lifting off from its Xichang spaceport in southwest China. No real information about the satellite was released, though its name, Shiyan, is part of a series of satellites that tests new designs for communications and remote sensing.

Next, the pseudo-company Galactic Energy placed three satellites into orbit, its solid-fueled Ceres-1 rocket lifting off from the Jiuquan spaeport in northwest China. Once again, little information was released about the satellites’ purpose.

With each launch, China’s state-run press also provided no information about where the lowers stages of both rockets landed inside China. This is especially of concern for the Long March 3C, which uses very toxic hypergolic fuels that can dissolve the skin.

The leaders in the 2025 launch race:

113 SpaceX
50 China
12 Rocket Lab
11 Russia

SpaceX still leads the rest of the world in successful launches, 113 to 87.

These numbers should change again by the end of today, with both SpaceX and China planning an additional launch each.

  • Startup PERSEI Space plans to test the use of tethers to remove space junk
    The concept, using the electromagnetic force produced as the tether moves through the Earth’s magnetic field to lower defunct satellites, is actually an old one. There have been a number of attempts to test it previously, especially by the space shuttle, but every time technical problems prevented the test from succeeding.

Astrobotic signs launch deal with Norway’s Andoya spaceport

9:01 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

The American lunar lander startup Astrobotic (which is now also a rocket startup) has signed a launch deal with Norway’s Andoya spaceport, where the company intends to launch its proposed reusable Xodiac rocket.

Astrobotic will perform their initial European Xodiac launch campaign operations from Andøya Space starting in 2026. Andøya Space will provide various services, including ground operations, flight preparation, and infrastructure support.

It will be wise to remain skeptical about Astrobotic’s rocket. The company owns the rights and technology of the vertical take-off-and-landing hopper developed and successfully tested by Masten Space System (which Astrobotic took over in 2022), but it also claimed in 2024 it would begin flying an upgraded suborbital version by 2025. No such flights appear on the horizon at this moment.

At the same time, developing a new rocket always involves delays. It will be quite exciting if Astrobotic succeeds in entering the launch market in the next year or so.

As for the Andoya spaceport, it continues to be in the lead among the four spaceports proposed surrounding the Norwegian Sea. Norway has made its licensing arrangement smooth and easy, the spaceport is well located, and it already has another launch contract with the German rocket startup Isar Aerospace, which attempted its first launch there earlier this year (albeit a failure). Moreover, Andoya has signed an agreement with the U.S. allowing American commercial companies to launch there, which is likely why Astrobotic made its deal.

Esrange’s location in the interior places it at a disadvantage, while red tape have badly stymied the two spaceports proposed in the United Kingdom.

A simple phone device for kids

8:40 am

A British company is selling a very simple phone device for young children that allows them to stay in contact with their parents, including GPS location, without giving them a touchscreen and any access to the web.

The Messenger, from London-based outfit Karri, is meant to help kids aged 5-13 become more independent, while giving their parents peace of mind. It’s designed entirely around voice messaging, so you can chat with your child one-on-one, or connect them with other family members in a group conversation.

This is actually the company’s second-generation Messenger with an improved design over the first from 2023. It features a dot matrix display, a speaker, and most importantly, a “slide to talk” button in the center. Slide it down to listen to a voice message you’ve just received, slide up and hold to record a reply, and short slide up to send it off.

Considering the increasing evidence that smartphones do real damage to kids during their development ages, this kind of option makes sense. So does a simple flip phone, but this device provides a simpler and more limited alternative.

Amazon gets first airline customer for its Kuiper constellation

8:05 am

Amazon yesterday signed up its first airline customer, JetBlue, the airline agreeing to provide in-flight WiFi to its passengers using the Kuiper constellation.

Amazon’s satellite internet service, Project Kuiper, will partner with JetBlue to provide in-flight Wi-Fi starting in 2027. It’s Project Kuiper’s first deal with an airline as it aims to keep up with the SpaceX-owned Starlink, which has already snagged satellite internet agreements with United Airlines, Hawaiian Airlines, Air France, and several others.

JetBlue must have gotten a truly great deal to go with Kuiper. It could start providing Starlink to passengers now if it wished, instead of waiting until 2027 with Kuiper. And even that date remains uncertain, considering how few satellites Amazon has so far launched (just over a hundred) when it needs at least 1,600 by next July to meet its FCC license requirements.

SpaceX launches another 28 Starlink satellites

7:16 am

SpaceX in the wee hours last night successfully placed another 28 Starlink satellites into orbit, its Falcon 9 rocket lifting off from the Kennedy Space Centery in Florida.

The first stage completed its 27th flight, landing on a drone ship in the Atlantic. SpaceX now has one booster with 30 flights and three with 27 flights, putting these stages in the same league with the three most flown space shuttles, Discovery (39), Atlantis (33), and Columbia (28). Expect these boosters to all pass Discovery in the near future, with several more Falcon 9 boosters about to enter this league as well.

The leaders in the 2025 launch race:

113 SpaceX
48 China
12 Rocket Lab
11 Russia

SpaceX now leads the rest of the world in successful launches, 113 to 85.

A glittering false-color image from Webb

A glittering false color image from Webb
Click for original image.

Cool image time! The picture to the right, reduced and sharpened to post here, was released today by the science team of the Webb Space Telescope. It shows in infrared false colors a spectacular star-forming region about 5,500 light years away, surrounded by glowing clouds.

Called Pismis 24, this young star cluster resides in the core of the nearby Lobster Nebula, approximately 5,500 light-years from Earth in the constellation Scorpius. Home to a vibrant stellar nursery and one of the closest sites of massive star birth, Pismis 24 provides rare insight into large and massive stars. Its proximity makes this region one of the best places to explore the properties of hot young stars and how they evolve.

At the heart of this glittering cluster is the brilliant Pismis 24-1. It is at the center of a clump of stars above the jagged orange peaks, and the tallest spire is pointing directly toward it. Pismis 24-1 appears as a gigantic single star, and it was once thought to be the most massive known star. Scientists have since learned that it is composed of at least two stars, though they cannot be resolved in this image. At 74 and 66 solar masses, respectively, the two known stars are still among the most massive and luminous stars ever seen.

…Super-hot, infant stars –some almost 8 times the temperature of the Sun – blast out scorching radiation and punishing winds that are sculpting a cavity into the wall of the star-forming nebula. That nebula extends far beyond NIRCam’s field of view. Only small portions of it are visible at the bottom and top right of the image. Streamers of hot, ionized gas flow off the ridges of the nebula, and wispy veils of gas and dust, illuminated by starlight, float around its towering peaks.

The universe is truly beautiful, if we look at it the right way.

Sunspot update: In August sunspot activity continued to rise

2:28 pm

Time for this month’s sunspot update. To do this each month I begin by taking NOAA’s own monthly update of its graph of sunspot activity and annotating it with extra information to illustrate the larger scientific context.

This annotated graph showing the August activity is below, and for the third month in a row sunspot activity increased (as indicated by the green dot), so that the August number of sunspots now closely matched the April 2025 prediction by NOAA’s panel of solar scientists that the Sun was finally beginning its ramp down from solar maximum.

Gemini South telescope captures Comet 3I/Atlas’s growing tail

1:43 pm

Comet 3I/Atlas
Click for original image.

Using the Gemini South telescope in Chile, astronomers have taken new images of interstellar Comet 3I/Atlas as it moves through the solar system, this time capturing the slow growth of its tail.

The picture to the right, cropped, reduced, and sharpened to post here, shows that tail trailing off to the left. The stars are streaks because it required four exposures in different wavelengths to produce the image. The comet was held steady while the stars shifted after each exposure.

In the images captured during the session, the comet displays a broad coma — a cloud of gas and dust that forms around the comet’s icy nucleus as it gets closer to the Sun — and a tail spanning about 1/120th of a degree in the sky (where one degree is about the width of a pinky finger on an outstretched arm) and pointing away from the Sun. These features are significantly more extended than they appeared in earlier images of the comet, showing that 3I/ATLAS has become more active as it travels through the inner Solar System.

So far, all the evidence continues to show that though 3I/Atlas has an interstellar origin, it is a relatively ordinary comet, simply unique in the manner all objects of a category are unique. As the scientists pour over the comet’s spectroscopy we might find its make-up is somewhat different than comets from our own solar system, but the data so far suggests that the differences are not likely to be that startling.

Spanish startup signs three customers for first flight of its returnable capsule

9:30 am

The Spanish startup Orbital Paradigm today announced it has signed up three customers for the first flight of a subscale version of its Kestrel returnable capsule.

As it prepares for the inaugural flight of its return capsule, Orbital Paradigm has developed a subscale prototype to validate key technologies that will be used aboard Kestrel. According to the company, the prototype was built in less than a year for under €1 million.

In a 4 September announcement, Orbital Paradigm stated that its KID demonstrator will carry payloads for ALATYR (France), Leibniz University Hannover (Germany), and an undisclosed third customer. While the 4 September announcement did not include details about the Leibniz University Hannover payload or that of the undisclosed customer, ALATYR CEO Emeric Lhomme said his company’s payloads would demonstrate its robotic laboratory technology, which is designed to support microgravity research and production.

The company is also planning a second test flight with another subscale test spacecraft. Once operational in the 2030s, the company hopes to fly Kestrel monthly on three month missions.

The returnable capsule industry is certainly heating up. The American company Varda might have been first to do this in 2023-2024, but since then the field has gotten very crowded. In the U.S. we now have Inversion Space, Sierra Space, and even SpaceX using Starship.

In Europe we have The Exploration Company in France with its Nyx capsule, the German startup Atmos with its Phoenix capsule, the Spanish startup PLD with its Lince capsule, and the Luxembourg startup Space Cargo with its Bentobox capsule.

In addition, both China and Russia have recently flown returnable capsules, though it is not clear either has profit in mind.

This flood of startups strongly suggests there is great interest in the investment community for manufacturing products in space. While it is likely some of these startups will go belly-up, their number tells us that there is money to be made in this area, now that the cost of launch has dropped so significantly. With the expected advent of new rocket companies in the next two years, that cost will lower even further.

SpaceX gets FAA approval to double its annual launches from Cape Canaveral

9:02 am

After several years of paperwork, the FAA yesterday approved SpaceX’s request to double its launch rate at the Space Force’s Cape Canaveral spaceport.

In addition to the annual launch increase from 50 launches to up to 120, the Federal Aviation Administration’s environmental review also approved a new on-site landing zone that could accommodate up to 34 booster landings per year. These boosters are the reusable first-stage portions of Falcon 9 rockets that SpaceX lands and refurbishes for future flights.

The review, finalized on Wednesday, found what’s known as a “Mitigated Finding of No Significant Impact,” meaning the proposed changes “would not significantly impact the quality of the human environment” under federal law, with impacts reduced by specific protective measures. [emphasis mine]

The highlighted words illustrate the absurdity of these environmental reviews. We know without doubt and without any major review that rocket launches do no harm to the environment or wildlife. We have seven decades of data in Florida proving it.

According to the article both the FAA and the Space Force still need to issue further approvals before this request can go forward. Expect the Space Force to agree, without much bother. The FAA needs to amend SpaceX’s launch licenses, and this should also happen relatively quick, especially with Trump as president.
