Following a successful May 4th launch atop Falcon 9, SpaceX’s latest Cargo Dragon spacecraft is just a few hours away from starting its International Space Station (ISS) berthing sequence.

Scheduled to begin around 5:30 am EDT (09:30 UTC), SpaceX operations staff will command Dragon to continue a cautious ISS approach. Several hours later, the spacecraft will be quite literally grabbed by station astronauts and gently berthed with one of the space station’s several Common Berthing Mechanism (CBM) ports. Once Cargo Dragon has been safely joined with the ISS, the station’s crew of astronauts can begin the intensive process of unpacking more than 1500 kg (3300 lb) of pressurized cargo, including dozens of time-sensitive and complex science experiments.

Aside from the 1.5 tons of cargo contained inside Dragon’s climate-controlled cabin, ISS astronauts and ground-based NASA controllers will again use the space station’s robotic Canadarm2 manipulator to extract two large unpressurized payloads from Dragon’s trunk. The ‘flagship’ instrument of CRS-17 is NASA’s Orbiting Carbon Observatory-3 (OCO-3), an upgraded follow-on to OCO-2 that should dramatically improve the quantity and quality of data available on the distribution of carbon in the Earth’s atmosphere. The second trunk-stashed payload is known as STP-H6 and is carrying around half a dozen distinct experiments.

Both STP-H6 and OCO-3 will be installed on the outside of the space station with the help of Canadarm2, an extremely useful capability that limits the need for astronauts to suit up and perform risky and time-consuming EVAs (extra-vehicular activities) outside the ISS. With its trunk emptied, Cargo Dragon will eventually discard the section to burn up in Earth’s atmosphere just before the reusable capsule begins its own reentry.

Unlike several other spacecraft with service sections, both proposed, flying, or retired, SpaceX’s Dragon spacecraft strive to minimize the complexity and cost of their expendable service sections. For both Cargo and Crew Dragon, the trunk serves as a structural adapter for unpressurized payloads and the Falcon-Dragon interface, hosts solar arrays and radiators, and doesn’t do much else. All propulsion, plumbing, and major avionics are kept within the capsule to maximize reusability.

Defining “slow and steady”

The process of berthing or docking with the ISS is a fundamentally cautious thing, developed by NASA, Roscosmos, and other international partners through forced and painful trial and error. In short, the road to today’s cautious procedures has been paved with countless failures and close calls over decades of space activity. For Cargo Dragon, the process involves berthing, more passive and less complex than docking. Outside of a dozen or so meters, the processes begin quite similarly. Cargo Dragon (Dragon 1) will very slowly approach the station’s several-hundred-meter keep out zone, typically no faster than a few m/s (mph).

Then follows a back-and-forth process of stop and go, in which SpaceX commands Dragon forward, halts at set locations, verifies performance and station readiness with NASA, and repeat. Once within 10 or so meters of the ISS, Dragon will begin carefully stationkeeping, essentially a version of formation flying without a hint of aerodynamic forces. ISS astronauts will then command the Canadarm2 robotic arm toward a sort of target/handle combo located on the spacecraft. The arm follows similar stop-start procedures before finally grappling Dragon, at which point the astronauts in command are legally required (/s) to quip something along the lines of “We’ve caught ourselves a Dragon!”

From start to finish, the process takes about 1.5 hours under optimal conditions. Around 2.5 hours after that, Canadarm2 will physically berth Dragon with one of several ISS berthing ports. Soon after, station astronauts can open Dragon’s hatch, snag some fresh goodies, and begin the unpacking process. CRS-17’s ISS arrival operations will be covered live on NASA TV.

Brazil’s Supreme Federal Court has ordered the closure of an investigation involving Elon Musk and social media platform X. The inquiry had been pending for about two years and examined whether the platform was used to coordinate attacks against members of the judiciary.

The decision was issued by Supreme Court Justice Alexandre de Moraes following a recommendation from Brazil’s Prosecutor-General Paulo Gonet.

According to a report from Agencia Brasil, the investigation conducted by the Federal Police did not find evidence that X deliberately attempted to attack the judiciary or circumvent court orders.

Prosecutor-General Paulo Gonet concluded that the irregularities identified during the probe did not indicate fraudulent intent.

Justice Moraes accepted the prosecutor’s recommendation and ruled that the investigation should be closed. Under the ruling, the case will remain closed unless new evidence emerges.

The inquiry stemmed from concerns that content on X may have enabled online attacks against Supreme Court justices or violated rulings requiring the suspension of certain accounts under investigation.

Justice Moraes had previously taken several enforcement actions related to the platform during the broader dispute involving social media regulation in Brazil.

These included ordering a nationwide block of the platform, freezing Starlink accounts, and imposing fines on X totaling about $5.2 million. Authorities also froze financial assets linked to X and SpaceX through Starlink to collect unpaid penalties and seized roughly $3.3 million from the companies’ accounts.

Moraes also imposed daily fines of up to R$5 million, about $920,000, for alleged evasion of the X ban and established penalties of R$50,000 per day for VPN users who attempted to bypass the restriction.

Brazil remains an important market for X, with roughly 17 million users, making it one of the platform’s larger user bases globally.

The country is also a major market for Starlink, SpaceX’s satellite internet service, which has surpassed one million subscribers in Brazil.

U.S. Federal Communications Commission (FCC) Chairman Brendan Carr criticized Amazon after the company opposed SpaceX’s proposal to launch a large satellite constellation that could function as an orbital data center network.

Carr made the remarks in a post on social media platform X.

Amazon recently urged the FCC to reject SpaceX’s application to deploy a constellation of up to 1 million low Earth orbit satellites that could serve as artificial intelligence data centers in space.

The company described the proposal as a “lofty ambition rather than a real plan,” arguing that SpaceX had not provided sufficient details about how the system would operate.

Carr responded by pointing to Amazon’s own satellite deployment progress.

“Amazon should focus on the fact that it will fall roughly 1,000 satellites short of meeting its upcoming deployment milestone, rather than spending their time and resources filing petitions against companies that are putting thousands of satellites in orbit,” Carr wrote on X.

Amazon has declined to comment on the statement.

Amazon has been working to deploy its Project Kuiper satellite network, which is intended to compete with SpaceX’s Starlink service. The company has invested more than $10 billion in the program and has launched more than 200 satellites since April of last year.

Amazon has also asked the FCC for a 24-month extension, until July 2028, to meet a requirement to deploy roughly 1,600 satellites by July 2026, as noted in a CNBC report.

SpaceX’s Starlink network currently has nearly 10,000 satellites in orbit and serves roughly 10 million customers. The FCC has also authorized SpaceX to deploy 7,500 additional satellites as the company continues expanding its global satellite internet network.
