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.

Tesla makes big change to encourage Full Self-Driving purchases

Tesla Full Self-Driving was recently proven to be about ten times safer than a human driver in terms of accident frequency.

Tesla has made a big change to its Online Design Studio, hoping to encourage car buyers to purchase Full Self-Driving with their vehicles.

Now, when you look at ordering a car on Tesla’s website, the portion of the page that formerly showed a render of Full Self-Driving capabilities has been replaced by a compilation of the suite’s performance in a variety of challenging scenarios.

It’s a great way to show off FSD’s impressive ability to work through road conditions that can even stump human drivers.

The move is much better than what the page previously illustrated. Now, people can see the true capabilities of the FSD suite and what it could do to change their perspective on how vehicles can be. Instead of a vessel of transportation, FSD turns cars into a semi-autonomous mode of travel.

Tesla Full Self-Driving is statistically very safe, logging about ten times the number of miles between accidents as human drivers, based on recent data the company released.

It is available for purchase in two different ways: an outright purchase for $8,000 or in a monthly subscription for $99. This enables the software to essentially do a vast majority of the legwork of driving. Drivers must keep their eyes on the road and be prepared to take over if an intervention is needed.

However, FSD has been proven to be a very accurate and safe way to travel. Tesla recently released a video of a drive from the Bay Area to Los Angeles, a nearly seven-hour trip, under FSD without a single intervention ever needed:

From a personal perspective, Tesla Full Self-Driving is a great way to travel because it truly takes a lot of the stress out of driving. In the past, I’ve used it during weekend Demo Drives to navigate around my town to see if it could handle some of the tougher traffic in my area. It became such an amazing and convenient alternative that when I went back to my car, I truly missed the advantage of having it.

Tesla offers new feature to save battery and reduce phantom drain

While in Low Power Mode, your vehicle continues to use energy for standby functions, screen activity, and Tesla app interactions. In cold weather, available energy may drop more quickly.”

Tesla is offering a new feature to help owners save battery and reduce phantom drain, an issue that some have complained of with their cars.

While Teslas are some of the most efficient EVs on the market, they utilize energy and battery life when they’re parked to keep certain features, like Sentry Mode, Summon Standby, and others, active in preparation for potential events that occur.

Keeping these features ready to perform utilizes energy, and if your car is parked at an airport where it could be sitting stagnant for a few days, the battery percentage could start to dwindle pretty significantly.

Because of this, Tesla is rolling out a new feature called “Low Power Mode,” which will automatically disable a handful of settings to combat battery dwindling and phantom battery drain.

Tesla writes in the release notes for the feature:

“When Low Power Mode is enabled, your vehicle will conserve energy by automatically disabling the following features:

    • Sentry Mode
    • Summon Standby
    • Outlets
    • Keep Accessory Power On
    • Keep Climate On and Camp Mode
    • Scheduled Preconditioning
    • Cabin Overheat Protection

While charging with Low Power Mode enabled:

    • Sentry Mode and accessory power will remain available
    • Keep Climate On and Camp Mode are only available when Supercharging

While in Low Power Mode, your vehicle continues to use energy for standby functions, screen activity, and Tesla app interactions. In cold weather, available energy may drop more quickly.”

This feature seemed to be a reaction to a past issue that an owner had as their Cybertruck continued to utilize energy even though the pickup was parked at an airport and the owner was in Japan. The Cybertruck had utilized a lot of energy to keep standby functions active, which left the owner in an interesting spot when they returned.

CEO Elon Musk stepped in, and it seems this feature might have been a reaction to that situation. This is an ideal thing to use if you’re looking to conserve your battery’s state of charge.

Tesla is bringing back something it took from the Model 3…for a price

“Modify your Model 3 by replacing the turn signal buttons on your steering wheel with turn signal stalks. This modification is included in the purchase price and is installed by a Tesla Service Center.”

Tesla is bringing back the Model 3’s turn signal stalk in China after removing the part with the refresh of the all-electric sedan early last year.

However, it is going to cost you.

In 2024, Tesla launched the Model 3 “Highland,” a refreshed version of the vehicle that included several large-scale changes. One of the most noticeable was the lack of a turn signal stalk, something the company chose to remove and instead implement turn signal buttons on the steering wheel.

The buttons were met with mixed reviews, as some drivers complained that it was too difficult to get used to them. Others had no problem with the change, noting that it was slightly more convenient for them or that they enjoyed the minimalistic look.

Now, Tesla is offering Model 3 owners in China the opportunity to replace the stalk for a price of ¥ 2,499, or about $350:

“Modify your Model 3 by replacing the turn signal buttons on your steering wheel with turn signal stalks. This modification is included in the purchase price and is installed by a Tesla Service Center.”

Tesla notes on its website that the service is available for Model 3 vehicles without stalks manufactured after February 7, 2025. Any car without a stalk that was manufactured before that date will have the service available to them in the future.

Installation can be performed at a Service Center or by the owner. However, Tesla notes that it is not responsible for any damages resulting from self-installation and recommends that the part be put in by an employee.

The cockpit of the Tesla lineup has been under intense scrutiny by the company in recent years. After a few changes to things like the stalk, steering wheel shape, and others, Tesla has usually given drivers the chance to have things reverted back to their preferences if they want.

They did this for the Model S and Model X a few years ago after implementing the yoke steering wheel.

The stalk was not supposed to be removed from the Model 3 and Model Y, but Tesla chose to do so with the refresh last year.

It seems the minimalization of the cockpit, overall, is a move that prepares drivers for autonomy, as eventually, Teslas will be void of pedals, steering wheels, and any other apparatus that are used to control the car.
