Juno flies past the Jupiter moon Thebe

Jupiter's moon Thebes
Click for original image.

Though the Jupiter orbiter Juno is in its final orbits as it is running out of fuel, on May 1, 2026 it did a close fly-by of the 50 by 72 mile-wide Jupiter moon Thebe, getting within 3,100 miles.

The picture to the right, cropped and expanded to post here, is the best image released from that fly-by. It is very comparable to a photo taken by the Galileo orbiter on January 4, 2000. Both show the very large crater, dubbed Zethus.

The picture was taken by Juno’s Stellar Reference Unit (SRU) camera, designed not to do science but to “image star fields for navigation.” Thus, the picture is somewhat fuzzy, and was pointed poorly so the moon is on the far right, almost off camera.

It is very unclear how much longer Juno will function. It has apparently survived attempts by the Trump administration to zero out its operating budget, but there have been indications that its fuel supply is low.

Multiple Russian, Chinese, and American satellites in maneuvering dance in orbit

Three different articles in the aerospace media today document multiple maneuvers by multiple military satellites from Russia, China, and America, either doing proximity operations near each other or moving close to another country’s satellites to spy on them.

This article in space.com describes the rendezvous operations of Russia’s Cosmos 2581, 2582, and 2583.

The satellites, known as COSMOS 2581 and COSMOS 2583, got within just 10 feet (3 meters) or so of each other on April 28, according to COMSPOC, a Pennsylvania-based space situational awareness software company. “This wasn’t a coincidental pass โ€” COSMOS 2583 performed several fine maneuvers to maintain this tight configuration,” COMSPOC wrote in a May 1 post on X, which featured an animation of the rendezvous.

The two satellites and a third one, COSMOS 2582, launched to low Earth orbit in February 2025 atop a Soyuz rocket. According to COMSPOC, all three of them were involved in the recent rendezvous and proximity operations (RPO), as was “Object F,” a subsatellite previously deployed by COSMOS 2583.

Then russianspaceweb.com had two different articles describing different similar operations. First, a set of satellites launched in February 2026 appeared to be testing operations in very low orbit, illegally transmitting data using frequencies that the International Telecommunications Union (ITU) allocates for amateur radio operations.

Finally, the website reported a complex dance between Russian, American, and Chinese satellites in geosynchronous orbit.

Almost immediately after entering the geostationary orbit, Kosmos-2589 was “approached” by a presumed American inspector satellite, officially known as USA-325. On April 19, 2026, the US satellite, itself drifting eastward relative to the geostationary position and the Earth’s surface, seemingly overshot Kosmos-2589, but once the Russian satellite stabilized at 98 East longitude, USA-325 stopped and returned. By around April 28, 2026, … one approach under favorable lighting conditions for the “inspector” was within 13 kilometers from Kosmos-2589, according to a team of observers from Exton, PA, cited by COMSPOC.

In turn … Kosmos-2589 essentially occupied a position registered by China under designation CHNSAT-98E, with three Chinese commercial and military satellites deployed in relative vicinity of that location.

… Moreover, in April 2026, China’s presumed inspector satellite โ€” TJS-10 โ€” pre-positioned itself at 92.4 degrees East longitude after an easterly drift, which would put it on a rendezvous course with Kosmos-2589 at 98.0 East longitude. Instead, the Chinese satellite stopped its drift with a maneuver on May 1, 2026, which “fixed” it in a geostationary orbit at 92.4 degrees East longitude, in the vicinity of the US AEHF military satellite, which carries high-security communications of the US military and its allies.

With this last story, we have this almost absurd situation: The U.S. satellites are spying on Russian satellites, which are spying on Chinese satellites, which are spying on American satellites.

All this maneuvering however indicates once again that the ability of commercial satellites to rendezvous with other objects — either to de-orbit space junk or repair damaged satellites — is only going to get better. The military might control these capabilities now, under a veil of secrecy, but such capabilities always leak out into the private sector shortly thereafter.

Russia arrests Angara contractor for fraud

Fraud is a given when it comes to government operations, whether in the U.S. or Russia. A contractor doing work on the production facilities for Russia’s new Angara rocket has now been arrested for stealing more than $7 million.

In May 2026, Gazeta.ru, citing regional courts, reported an arrest of Dmitry Zolotarev, the Director General at OOO RST Genpodryad, which was involved in renovations and upgrades of facilities for serial production of Angara rockets at PO Polyot under a contract with GKNPTs Khrunichev.

Zolotarev and his accomplices were accused of stealing 545 million rubles (approximately $7.3 million) during a period from 2022 to 2025, by submitting the Federal treasury agency in Moscow forged documents with an inflated purchase price of overhead cranes and pocketing the difference. According to Gazeta.ru, Zolotarev was suspected of other similar schemes and faced 10 years in prison if convicted.

Government routinely does a bad job in monitoring its spending, which thus creates an easy temptation for others to put their hands in the cookie jar and take what’s not theirs. We can see this same thing occurring now in the U.S. with many so-called “safety net” programs. Since Russia’s entire aerospace industry is government controlled, this kind of corruption therefore happens frequently within it.

Lockheed Martin fights request to ease 2018 restrictions on Northrop Grumman’s solid rocket business

A legal fight between Lockheed Martin and Northrop Grumman has broken out over Northrop Grumman’s recent request to the Federal Trade Commission (FTC) to ease a 2018 consent order that restricts Northrop Grumman’s ability to market its solid rocket motors (SRM).

On April 2, Northrop petitioned the Federal Trade Commission to drop a 2018 consent order helmed when Northrop acquired solid rocket motor maker Orbital ATK. The consent agreement requires Northrop to supply SRMs to its competitors in the missile market on a non-discriminatory basis and to firewall its SRM business away from its other operations.

At the time, the FTC believed the measure was necessary due to Northropโ€™s status as a prime contractor and Orbital ATKโ€™s position as one of only two American makers of solid rocket motors.

Northrop is not a major manufacturer in the American missile space, which is dominated by Raytheon and Lockheed. However, if the order is dropped, Northrop will be able to vertically integrate its solid rocket motor business with any munitions the company designs in the future โ€” including potentially prioritizing SRM supplies for Northrop over competitors, Lockheed stated in a response to the petition.

This consent order has prevented Northrop from marketing its solid-fueled rockets openly. Instead, it appears it forces the company to sell to its competitors, such as Lockheed, who then garners the big profits in marketing them. That order I think has also limited Northrop’s ability to use its boosters for other purposes, such as launching satellites.

Overall it appears this consent order has been very counter-productive, in hindering competition in the American solid-fueled rocket industry. At present there is a shortage of production capacity in the U.S., so much so that the Italian rocket company has moved in to market its own solid-fueled rockets here. In fact, it is selling its rockets to Lockheed and Raytheon, which suggests Northrop is entirely justified in asking to be released from this order.

Indian rocket startup Skyroot raises $60 million in private investment capital

Even as it prepares for the first orbital launch attempt of its Vikram-1 rocket, the Indian rocket startup Skyroot has raised $60 million in private investment capital in a recent funding round, bringing the total raised by the company to $160 million.

The startup announced it had raised $60 million at a valuation of $1.1 billion prior to the funding. The round was co-led by early Google investor Ram Shriram’s venture capital firm, Sherpalo Ventures, and Singapore’s sovereign wealth fund, GIC. New investors in the round include funds managed by BlackRock, Playbook Partners, Shanghvi Family Office, and others. Existing investors that also participated in the round include the founders of Greenko Group and Arkam Ventures.

The company hopes to launch Vikram-1 in about two months, though no specific launch window has been announced. The rocket is presently being shipped to India’s Sriharikota spaceport.

Will Canada’s Telesat really complete its Lightspeed constellation by 2028?

According to the most recent financial report from the Canadian satellite communications company Telesat, it expects its Lightspeed low-Earth-orbit (LEO) satellite constellation to be launched and operational by 2028.

During the first quarter, Telesat invested $171 million into the Lightspeed program, reflecting $19 million in operating expenses and $152 million in capital expenditures, bringing its total investment to date to approximately $2.7 billion.

The company reported advancing through several technical milestones in early 2026. โ€œDuring the quarter, we held further design reviews with our satellite and launch vehicle dispenser manufacturers and progressed our work on user terminals, network and satellite operations software development, and ground station deployments,โ€ noted Telesat President and CEO Dan Goldberg.

The company confirmed it remains fully funded, utilizing cash on hand and existing financing facilities, to reach full global commercial service around the end of the first quarter of 2028.

At the moment however the company has launched no satellites in this LEO constellation. Moreover, in a recent amendment to its FCC application, the company reduced the size of the constellation from 1,671 satellites to only 300, with no explanation.

We shall see what happens. My instincts sense a bit of blarney here. This constellation will likely launch, but I think the company’s proposed schedule is questionable.

Curiosity unintentionally picks up a rock slab

Sequence showing slab picked up and then dropped
Click for movie. Original images found here, here, here, and here.

In their latest drilling campaign using the drill on the Mars rover Curiosity, the science team picked up a big surprise that could have been a serious problem, but turned out all right in the end. When they tried to extract the drill from the hole, the drill instead stayed stuck to the rock, and picked the whole rock up instead.

The four images to the right show the sequence, sourced from here, here, here, and here.

On April 25, 2026, Curiosity drilled a sample from a rock nicknamed โ€œAtacama,โ€ which is an estimated 1.5 feet in diameter at its base, 6 inches thick and weighs roughly 28.6 pounds (13 kilograms). When the rover retracted its arm, the entire rock lifted out of the ground, suspended by the fixed sleeve that surrounds the rotating drill bit. Drilling has fractured or separated the upper layers of rocks in the past, but a rock has never remained attached to the drill sleeve. The team initially tried vibrating the drill to shake off the rock, but saw no change.

Then, on April 29, they tried reorienting Curiosityโ€™s robotic arm and vibrating the drill again. Imagery in the GIF shows sand falling from Atacama, but the rock stayed attached to the rover.

Finally, on May 1, Curiosityโ€™s team tried again, tilting the drill more, rotating and vibrating the drill, and spinning the drill bit. The team planned to perform these actions multiple times but the rock came off on the first round, fracturing as it hit the ground.

Had they not been able to release the rock it could have seriously impacted the mission, even ended it.

As noted by the science team in their own update today about this situation:

Future activities involve wrapping up the drill campaign on Atacama and, nominally, seeking a more firmly rooted drill target in order to collect drill tailings for analysis, which were lost from Atacama as part of the effort to dislodge the drill bit from the rock.

In other words, they are going to have hunt around for a better drill spot, as they really do want to study some drill samples at this location. They have left the boxwork area and have moved uphill closer to the pure sulfite unit, and want to see how the geology has changed.

The UK’s Sutherland spaceport now appears dead

Proposed or active spaceports in North Europe
Proposed or active spaceports in North Europe

In a news report yesterday about the failure of the United Kingdom’s rocket startup Orbex in February 2026, the following details about the Sutherland spaceport in Scotland suggests that spaceport is now defunct, with little chance of being revived.

Administrators say that one of Orbexโ€™s key remaining assets is the Sutherland Spaceport site near Melness – although the only construction work undertaken at the site is some 600m of access road. The company responsible for it, Sutherland Spaceport Ltd (SSL), remains financially stable, according to administrators. This means the site could still be sold or potentially restarted, even though no launch activity is currently taking place.

The spaceport sits on land leased from local crofters under a long-term arrangement managed through Highlands and Islands Enterprise. SSL holds a 50-year sublease, with an option to extend for 25 years, and a break clause in 2027.

Orbex had originally intended to launch from Sutherland — close to the rocket factory it had built — but local opposition by billionaire Anders Holch Povlsen (who is a major owner in the competing Saxavord spaceport on the Shetland Islands) as well as endless bureaucratic delays from the UK’s Civil Aviation Authority made that impossible. The company attempted to switch its launches to Saxavord, but the cost and new licensing requirements were too much.

No other launch company has expressed any interest in using Sutherland, and it appears none will be forthcoming in the near future. The red tape in the UK, combined with that powerful local opposition, has made Sutherland a pariah to the smallsat rocket companies looking for launch sites.

Though the spaceport might say it is “financially stable”, without any customers I guarantee it is going to disappear at some point.
