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.

Cargo Dragon completes test burn to raise ISS’s orbit

8:51 am

The cargo Dragon that docked with ISS in late August successfully completed yesterday an engine burn lasting more than five minutes to see if it could raise ISS’s orbit.

On Wednesday, Sept. 3, SpaceX’s Dragon completed an initial burn to test the spacecraft’s new capability to help maintain the altitude of the International Space Station. Two Draco engines located in the trunk of Dragon, which contains an independent propellant system, were used to adjust the space station’s orbit through a maneuver lasting five minutes, three seconds. The initial test burn increased the station’s altitude by around one mile at perigee, or low point of station’s orbit, leaving the station in an orbit of 260.9 x 256.3 miles. The new boost kit in Dragon will help sustain the orbiting lab’s altitude through a series of longer burns planned periodically throughout the fall of 2025.

The Dragon will remain docked with ISS until December. It is expected it will do additional test burns during that time.

NASA wishes to get this capability from its own spacecraft so as to no longer have to rely entirely on the Russians, who have traditionally done these orbital adjustments using its Progress cargo freighters. SpaceX likely also wants to do these tests as an adjunct to its contract to build the de-orbit vehicle that will bring ISS down, after it is retired.

Patterned frozen lava in Mars’ volcano country

12:55 pm

Patterned frozen lava
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken on May 31, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The camera team label this “patterned ground.” And it is indeed. Though the topography is almost flat for large distances, the ground itself has these various patterns on it, from meandering small ridges to stippled roughness to very smooth sections.

The location is at 4.6 degrees north latitude, in the dry equatorial regions of Mars. No near surface ice created these features. All we can deduce from this picture is that this landscape is relatively young, as there are no craters seen.

So what caused these features? The location as always provides a clue.

Radar images reveal near Earth asteroid to be a contact binary

12:06 pm

Peanut shaped asteroid
Click for original image.

Just after asteroid 1997 QK1 made its first really close pass of the Earth on August 20, 2025, scientists used the Goldstone radio antenna take 28 high resolution images and discovered that the asteriod is peanut shaped, meaning that it is a contact binary of two objects that have fused together.

Those images, cropped, reduced, and sharpened to post here, are shown to the right.

The asteroid is about 660 feet (200 meters) long and completes one rotation every 4.8 hours. It passed closest to our planet on the day before these observations were made at a distance of about 1.9 million miles (3 million kilometers), or within eight times the distance between Earth and the Moon. The 2025 flyby is the closest that 1997 QK1 has approached to Earth in more than 350 years. Prior to the recent Goldstone observations, very little was known about the asteroid.

These observations resolve surface features down to a resolution of about 25 feet (7.5 meters) and reveal that the object has two rounded lobes that are connected, with one lobe twice the size of the other. Both lobes appear to have concavities that are tens of meters deep.

Though this asteroid is classified as potentially dangerous, calculations of its orbit show it poses no threat for the “foreseeable future.”

That it is a contact binary reinforces the present theory that about 15% of all larger asteroids belong to this class.

Juno detects the aurora of the moon Callisto in Jupiter’s atmosphere

10:19 am

Though previous observations had detected auroras on Jupiter produced by three of its four Galilean moons — Io, Europa, and Ganymede — scientists had until now been unable to detect a similar aurora produced by the fourth, Callisto.

The Jupiter orbiter Juno finally accomplished this observation for the first time.

[T]o image Callisto’s footprint, the main auroral oval needs to move aside while the polar region is being imaged. And to bring to bear Juno’s arsenal of instruments studying fields and particles, the spacecraft’s trajectory must carry it across the magnetic field line linking Callisto and Jupiter.

These two events serendipitously occurred during Juno’s 22nd orbit of the giant planet, in September 2019, revealing Callisto’s auroral footprint and providing a sample of the particle population, electromagnetic waves, and magnetic fields associated with the interaction.

The research paper describing this detection has just been published.

These secondary auroras are caused by Jupiter’s powerful magnetic field.

The Juno mission itself is about to end. NASA did not approve a mission extension, and next month the science team will send the spacecraft into Jupiter’s atmosphere, where it will burn up. We will then have to wait five years for Europa Clipper to arrive in Jupiter orbit, followed a year later by Europe’s Juice orbiter.

While the propaganda press is condemning this decision, there is some logic to it. Juno has mostly completed its work. While new knowledge can certainly be gained if it remained operations for three more years, the amount of knowledge will be relatively small. And NASA does face a budget crunch. Better to spend its money on other things that can produce more bang to the buck.

France startup wins contract to build Starlink competitor

9:58 am

France’s space agency CNES has awarded a €31 million contract to France startup Univity to build a demo satellite to demonstrate internet and phone-to-satellite capabilities, as part a longer term plan to build a constellation that can compete with both SpaceX’s Starlink and AST SpaceMobile constellation, both already launched and in operation.

Founded in 2022 under the name Constellation Technologies & Operations, UNIVITY aims to develop a very low Earth orbit constellation to provide global high-speed, low-latency internet services. A prototype of the company’s regenerative 5G mmWave payload was part of a 23 June SpaceX Falcon 9 rideshare mission, hosted aboard the D-Orbit SpaceBound ION mission. The company expects to launch a pair of prototype satellites in 2027, followed by the deployment of its full constellation between 2028 and 2030.

This deal likely puts the final nail in the coffin of the European Space Agency’s (ESA) own government IRIS satellite constellation, which has been delayed, is expected to be very expensive and take a long time to get launched, and has already faced disinterest from many partners in ESA. That France is now going it alone likely ends any chance that IRIS will be funded.

Australian rocket startup Gilmour Space confirms successful operation of its first satellite

9:38 am

The Australian rocket startup Gilmour Space, which in July tried but failed to launch for the first time its Eris rocket, yesterday announced that its first orbiting satellite, dubbed ElaraSat MMS-1, is operating as expected after a June launch by SpaceX.

Launched aboard SpaceX’s Transporter-14 mission in June, the locally designed and built satellite bus carries a hyperspectral imager from CSIRO, Australia’s national science agency. Since reaching orbit, ElaraSat MMS-1 has completed platform commissioning, verified satellite bus systems are operating as expected, [and] demonstrated reliable S-band communications and X-band downlink.

If this company can succeed in getting its rocket operational as well as build satellites, it will have capabilities comparable to SpaceX, Rocket Lab, and Firefly, and will be in a very strong position to compete internationally.

Two more launches in past 24 hours, by Israel and SpaceX

9:04 am

Both Israel and SpaceX completed new launches during the evening hours yesterday. First, Israel placed an Ofek radar surveillance satellite into orbit, its small solid-fueld Shavit-2 rocket lifting off from an undisclosed location within the country, likely its Palmachim Airbase on the Mediterranean coast south of Tel Aviv. The launch occurred about the same time as SpaceX’s Starlink launch from Vandenberg, already reported last night.

This was Israel’s first launch in 2025, and the first since 2023. Since 2008 the country has launched seven military surveillance satellites, one about every two to four years or so.

Several hours later, in the wee hours of the morning, SpaceX completed another launch, placing 28 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its fourteenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

112 SpaceX
48 China
12 Rocket Lab
11 Russia

SpaceX now leads the rest of the world in successful launches, 112 to 85.
