After a minor issue at sea triggered a ~23-hour delay, a flight-proven Falcon 9 rocket lifted off without issue on April 28th, carrying an expendable upper stage and 60 Starlink internet satellites as part of its seventh launch and SpaceX’s ninth Starlink mission in 2021 alone.

As is now routine, Falcon 9 booster B1060 burned its nine Merlin 1D (M1D) engines for approximately two and a half minutes and separated from the integrated second stage and payload, which ignited a lone Merlin Vacuum (MVac) engine and continued on its way to orbit. During that approximately six-minute-long second stage burn, B1060 flipped to point its aft end towards the atmosphere, crested to an apogee greater than 120 km (~75 mi), performed a reentry burn to slow down and limit heating, and aced its seventh drone ship landing in ten months.

Known as Starlink-24, the mission is SpaceX’s two-dozenth operational Starlink launch since ‘v1.0’ satellite launches began less than 18 months ago. Including an earlier batch of 60 v0.9 Starlink prototypes launched in May 2019, the vast majority of which have been intentionally deorbited, SpaceX has now launched more than 1500 Starlink satellites. Of the 1450 operational spacecraft launched in 17 months, 1435 remain in orbit and some 1430 – 98.6% – are still under SpaceX’s control. With Starlink-24 complete, SpaceX may also possess more active Starlink satellites in orbit than all other commercial satellites combined.

As previously discussed on Teslarati, several sources suggest that Starlink-24 will kick off an extremely busy May and June launch manifest for SpaceX.

“Starlink-24 should also be SpaceX’s third and final launch this April, opening the door for as many as four more Starlink launches (Starlink-25 through Starlink-28) in May, according to Next Spaceflight. Spaceflight Now reports that Starlink-25 is scheduled to launch in “early May,” possibly just a few days to a week after Starlink-24. All four of SpaceX’s workhorse Falcon 9 boosters (B1049, B1051, B1058, B1060) would have to fly once – and one booster twice – to launch Starlink-24 through Starlink-28 between now and the end of May.

No earlier than (NET) June 1st, a Falcon 9 rocket is scheduled to launch radio provider SiriusXM’s SXM-8 radio satellite. SpaceX is scheduled to launch its second upgraded Cargo Dragon spacecraft as early as June 3rd, just two days after SXM-8. Last but likely not least, launch photographer Ben Cooper reports that a flight-proven SpaceX Falcon 9 rocket is scheduled to launch the US military’s fifth upgraded GPS III navigation satellite on June 17th.”

Including Starlink-24, that means that SpaceX appears to have up to eight Falcon 9 launches scheduled in the next seven weeks and possibly even a ninth or tenth mission in the last two weeks of June. Starlink-24 is SpaceX’s 12th launch this year, leaving the company firmly on track to complete at least 36 orbital launches in 2021 – nearly 40% more than its current record of 26 launches completed in 2020.

Tesla prides itself on producing some of the safest vehicles on the road today. Based on recent findings from the Euro NCAP, the 2025 Model 3 sedan continues this tradition, with the vehicle earning a 5-star overall safety rating from the agency.

Standout Safety Features

As could be seen on the Euro NCAP’s official website, the 2025 Model 3 achieved an overall score of 90% for Adult Occupants, 93% for Child Occupants, 89% for Vulnerable Road Users, and 87% for Safety Assist. This rating, as per the Euro NCAP, applies to the Model 3 Rear Wheel Drive, Long Range Rear Wheel Drive, Long Range All Wheel Drive, and Performance All Wheel Drive.

The Euro NCAP highlighted a number of the Model 3’s safety features, such as its Active Hood, which automatically lifts during collisions to mitigate injury risks to vulnerable road users, and Automatic Emergency Braking System, which now detects motorcycles through an upgraded algorithm. The Euro NCAP also mentioned the Model 3’s feature that prevents initial door opening if someone is approaching the vehicle’s blind spot.

Standout Safety Features

In a post on its official Tesla Europe & Middle East account, Tesla noted that the company is also introducing new features that make the Model 3 even safer than it is today. These include functions like head-on collision avoidance and crossing traffic AEB, as well as Child Left Alone Detection, among other safety features.

“We also introduced new features to improve Safety Assist functionality even further – like head-on collision avoidance & crossing traffic AEB – to detect & respond to potential hazards faster, helping avoid accidents in the first place.

“Lastly, we released Child Left Alone Detection – if an unattended child is detected, the vehicle will turn on HVAC & alert caregivers via phone app & the vehicle itself (flashing lights/audible alert). Because we’re using novel in-cabin radar sensing, your Tesla is able to distinguish between adult vs child – reduced annoyance to adults, yet critical safety feature for kids,” Tesla wrote in its post on X.

Below is the Euro NCAP’s safety report on the 2025 Tesla Model 3 sedan.

United States Department of Transportation (USDOT) Secretary Sean Duffy recently visited Tesla’s Gigafactory Texas complex, where he toured the factory’s production lines and spoke with CEO Elon Musk. In a video posted following his Giga Texas visit, Duffy noted that he believes there should be a national standard for autonomous vehicles in the United States.

Duffy’s Giga Texas Visit

As could be seen in videos of his Giga Texas visit, the Transportation Secretary seemed to appreciate the work Tesla has been doing to put the United States in the forefront of innovation. “Tesla is one of the many companies helping our country reach new heights. USDOT will be right there all the way to make sure Americans stay safe,” Duffy wrote in a post on X. 

He also praised Tesla for its autonomous vehicle program, highlighting that “We need American companies to keep innovating so we can outcompete the rest of the world.”

National Standard

While speaking with Tesla CEO Elon Musk, the Transportation Secretary stated that other autonomous ride-hailing companies have been lobbying for a national standard for self-driving cars. Musk shared the sentiment, stating that “It’d be wonderful for the United States to have a national set of rules for autonomous driving as opposed to 50 independent sets of rules on a state-by-state rules basis.”

Duffy agreed with the CEO’s point, stating that, “You can’t have 50 different rules for 50 different states. You need one standard.” He also noted that the Transportation Department has asked autonomous vehicle companies to submit data. By doing so, the USDOT could develop a standard for the entire United States, allowing self-driving cars to operate in a manner that is natural and safe.

Tesla posts Optimus’ most impressive video demonstration yet

The humanoid robot was able to complete all the tasks through a single neural network.

When Elon Musk spoke with CNBC’s David Faber in an interview at Giga Texas, he reiterated the idea that Optimus will be one of Tesla’s biggest products. Seemingly to highlight the CEO’s point, the official Tesla Optimus account on social media platform X shared what could very well be the most impressive demonstration of the humanoid robot’s capabilities to date.

Optimus’ Newest Demonstration

In its recent video demonstration, the Tesla Optimus team featured the humanoid robot performing a variety of tasks. These include household chores such as throwing the trash, using a broom and a vacuum cleaner, tearing a paper towel, stirring a pot of food, opening a cabinet, and closing a curtain, among others. The video also featured Optimus picking up a Model X fore link and placing it on a dolly.

What was most notable in the Tesla Optimus team’s demonstration was the fact that the humanoid robot was able to complete all the tasks through a single neural network. The robot’s actions were also learned directly from Optimus being fed data from first-person videos of humans performing similar tasks. This system should pave the way for Optimus to learn and refine new skills quickly and reliably.

Tesla VP for Optimus Shares Insight

In a follow-up post on X, Tesla Vice President of Optimus (Tesla Bot) Milan Kovac stated that one of the team’s goals is to have Optimus learn straight from internet videos of humans performing tasks, including footage captured in third person or by random cameras.

“We recently had a significant breakthrough along that journey, and can now transfer a big chunk of the learning directly from human videos to the bots (1st person views for now). This allows us to bootstrap new tasks much faster compared to teleoperated bot data alone (heavier operationally).

“Many new skills are emerging through this process, are called for via natural language (voice/text), and are run by a single neural network on the bot (multi-tasking). Next: expand to 3rd person video transfer (aka random internet), and push reliability via self-play (RL) in the real-, and/or synthetic- (sim / world models) world,” Kovac wrote in his post on X.
