SpaceX sends two drone ships to sea for back-to-back Starlink, astronaut launches

Published

Update: SpaceX has rolled out Crew-4’s Falcon 9 and Crew Dragon in anticipation of prelaunch testing. However, due to poor weather in landing regions, NASA and SpaceX have also delayed the private Axiom-1 crew’s return to Earth a second time.

Without the undocking time confirmed, it’s likely that Crew-4 will be pushed back to April 24th or 25th at the earliest. Starlink 4-14, nonetheless, appears to remain on track for an April 21st launch attempt.

SpaceX has sent both of its East Coast drone ships to sea to support an upcoming pair of back-to-back Falcon 9 launches and landings.

The ‘autonomous spaceport drone ship ‘ (ASDS) Just Read The Instructions (JRTI) left first, exiting Florida’s Port Canaveral with the help of a tugboat on April 16th. On April 18th, drone ship A Shortfall of Gravitas (ASOG) followed suit, shadowing JRTI en route to a similar location northeast of Cape Canaveral. Both should arrive at their respective Atlantic Ocean landing zones within a few days.

No earlier than (NET) 11:16 am EDT (15:16 UTC), Thursday, April 21st, SpaceX is scheduled to launch a well-worn Falcon 9 booster carrying a new upper stage and the latest batch of ~50 Starlink V1.5 satellites. Less than two full days later, a different Falcon 9 rocket is scheduled to launch a new Crew Dragon spacecraft and four NASA and ESA astronauts on their way to the International Space Station.

Starlink 4-14 – the 14th mission carrying satellites destined for the fourth of five Starlink orbital ‘shells’ – will be SpaceX’s 9th Starlink launch and 15th launch overall in 2022, averaging just shy of one launch per week. The mission should also leave SpaceX with more than 2100 working Starlink satellites in orbit – likely not far off from half of all operational satellites in Earth orbit.

SpaceX appears to have assigned Falcon 9 booster B1061 to the launch after the rocket – already integrated with a new upper stage – was spotted on the way to Cape Canaveral Space Force Station (CCSFS) Launch Complex 40 (LC-40) on April 18th. Starlink 4-14 will be B1060’s 12th launch since June 30th, 2020, tying Falcon 9 B1051’s booster reuse record but accomplishing the feat almost 15 months faster. It’s unlikely that B1051 will ever retake its crown from B1060. Based on past performance, B1060 could easily fly another 4-6 times before the end of 2022 if it survives Starlink 4-14.

As few as 42 hours later, Falcon 9 booster B1067 could lift off for the fourth time with a new Crew Dragon capsule – C212 or “Freedom” – and a team of four professional astronauts as part of NASA’s Crew-4 mission at 5:26 am EDT (09:26 UTC), April 23rd. Crew-4 will be SpaceX’s seventh astronaut launch since May 2020 and its fourth operational crew transport mission for NASA. A few days after Crew Dragon C212 docks with the International Space Station (ISS), four Crew-3 astronauts will board a different Crew Dragon and return to Earth, handing off the US segment to Crew-4.

However, two Crew Dragons are already docked to the ISS, taking up both available International Docking Adapter (IDA) ports. Before Crew-4 can launch, Axiom-1 – SpaceX’s first all-private astronaut mission to the space station – must undock and return to Earth. On April 18th, that undocking was delayed about 15 hours by poor weather to 10 pm EDT, April 19th, pushing splashdown and recovery off the coast of Florida to mid-afternoon, April 20th. NASA and SpaceX will then have about 60 hours to analyze any data gathered from the completed Axiom-1 mission and determine whether or not to proceed with Crew-4 on April 23rd.

Tesla Full Self-Driving appears to have a new behavior that is the perfect answer to aggressive drivers.

According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.

With FSD’s constantly-changing Speed Profiles, it seems as if this solution could help eliminate the need to tinker with driving modes from the person in the driver’s seat. This tends to be one of my biggest complaints from FSD at times.

A video posted on X shows a Tesla on Full Self-Driving pulling over to the shoulder on windy, wet roads after another car seemed to be following it quite aggressively. The car looks to have automatically sensed that the vehicle behind it was in a bit of a hurry, so FSD determined that pulling over and letting it by was the best idea:

We can see from the clip that there was no human intervention to pull over to the side, as the driver’s hands are stationary and never interfere with the turn signal stalk.

This can be used to override some of the decisions FSD makes, and is a great way to get things back on track if the semi-autonomous functionality tries to do something that is either unneeded or not included in the routing on the in-car Nav.

FSD tends to move over for faster traffic on the interstate when there are multiple lanes. On two-lane highways, it will pass slower cars using the left lane. When faster traffic is behind a Tesla on FSD, the vehicle will move back over to the right lane, the correct behavior in a scenario like this.

Perhaps one of my biggest complaints at times with Full Self-Driving, especially from version to version, is how much tinkering Tesla does with Speed Profiles. One minute, they’re suitable for driving on local roads, the next, they’re either too fast or too slow.

When they are too slow, most of us just shift up into a faster setting, but at times, even that’s not enough, see below:

There are times when it feels like it would be suitable for the car to just pull over and let the vehicle that is traveling behind pass. This, at least up until this point, it appears, was something that required human intervention.

Now, it looks like Tesla is trying to get FSD to a point where it just knows that it should probably get out of the way.

Tesla’s Megapack battery systems will be deployed as part of a 400MW AI data center campus in Uberlândia, Brazil. The initiative is described as one of Latin America’s largest AI infrastructure projects.

The project is being led by RT-One, which confirmed that the facility will integrate Tesla Megapack battery energy storage systems (BESS) as part of a broader industrial alliance that includes Hitachi Energy, Siemens, ABB, HIMOINSA, and Schneider Electric. The project is backed by more than R$6 billion (approximately $1.1 billion) in private capital.

According to RT-One, the data center is designed to operate on 100% renewable energy while also reinforcing regional grid stability.

“Brazil generates abundant energy, particularly from renewable sources such as solar and wind. However, high renewable penetration can create grid stability challenges,” RT-One President Fernando Palamone noted in a post on LinkedIn. “Managing this imbalance is one of the country’s growing infrastructure priorities.”

By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.

“The facility will be capable of absorbing excess electricity when supply is high and providing stabilization services when the grid requires additional support. This approach enhances resilience, improves reliability, and contributes to a more efficient use of renewable generation,” Palamone added.

The model mirrors approaches used in energy-intensive regions such as California and Texas, where large battery systems help manage fluctuations tied to renewable energy generation.

The RT-One President recently visited Tesla’s Megafactory in Lathrop, California, where Megapacks are produced, as part of establishing the partnership. He thanked the Tesla team, including Marcel Dall Pai, Nicholas Reale, and Sean Jones, for supporting the collaboration in his LinkedIn post.

Starlink is now powering Europe’s first commercial satellite-to-smartphone service, as Virgin Media O2 launches a space-based mobile data offering across the UK.

The new O2 Satellite service uses Starlink’s low-Earth orbit network to connect regular smartphones in areas without terrestrial coverage, expanding O2’s reach from 89% to 95% of Britain’s landmass.

Under the rollout, compatible Samsung devices automatically connect to Starlink satellites when users move beyond traditional mobile coverage, according to Reuters.

The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools. O2 is pricing the add-on at £3 per month.

By leveraging Starlink’s satellite infrastructure, O2 can deliver connectivity in remote and rural regions without building additional ground towers. The move represents another step in Starlink’s push beyond fixed broadband and into direct-to-device mobile services.

Virgin Media O2 chief executive Lutz Schuler shared his thoughts about the Starlink partnership. “By launching O2 Satellite, we’ve become the first operator in Europe to launch a space-based mobile data service that, overnight, has brought new mobile coverage to an area around two-thirds the size of Wales for the first time,” he said.

Satellite-based mobile connectivity is gaining traction globally. In the U.S., T-Mobile has launched a similar satellite-to-cell offering. Meanwhile, Vodafone has conducted satellite video call tests through its partnership with AST SpaceMobile last year.

For Starlink, the O2 agreement highlights how its network is increasingly being integrated into national telecom systems, enabling standard smartphones to connect directly to satellites without specialized hardware.
