SpaceX test emergency egress drills ahead of upcoming crew mission
NASA and SpaceX are progressing full steam ahead to an epic launch of the crewed Dragon spacecraft. Known as Demo-2, the mission is estimated to blast off in mid-to-late May, marking the first-ever flight of the Dragon with astronauts on board.
As part of that historic mission, two NASA astronauts — Doug Hurley and Bob Behnken — will launch to the International Space Station, where they will spend a still to be determined amount of time. The mission, deemed critical by NASA, is progressing as planned despite the coronavirus outbreak that’s spreading across the country.
To that end, NASA and SpaceX personnel, along with the crew, practiced essential safety drills and launch day procedures at the space agency’s Kennedy Space Center in Florida. SpaceX’s Crew Dragon capsule, and its Falcon 9 launcher, are equipped with numerous safety features designed to protect astronauts in the event of an emergency. And NASA wants to make sure they work.
One system — known as a launch escape system — was recently tested in-flight, proving that if something is wrong with the Falcon, the crews can be whisked away to safety by Dragon. But what if something goes wrong on the launch pad? The launchpad is equipped with a zipline that can be used to whisk astronauts quickly back to the ground should an emergency happen.
On April 3, @NASA and @SpaceX conducted an emergency egress exercise at Launch Complex 39A at @NASAKennedy.

On Friday (April 3), SpaceX and NASA completed an important test of that system. Teams simulated an “emergency egress”, running through a series of steps designed to transport the astronauts off the pad, and ensure their safety in the event that a serious problem crops up prior to liftoff.
“Teams rehearsed locating injured personnel on the 265-foot-level of the launch tower, loading them into the pad’s slidewire baskets and safely descending the tower, then successfully loading the injured participants into Mine Resistant Ambush Protected (MRAP) vehicles staged at the pad perimeter,” NASA officials wrote in an update.
This follows a series of simulations that the teams ran last month. They gathered in Firing Room 4, SpaceX HQ, and Johnson Space Center to run through launch simulations, ensuring the crew and launch control teams were ready for anything on the day of launch.
The flight is one for the history books as it marks the return of human spaceflight from U.S. soil since 2011. When the space shuttle program ended, NASA and other agencies around the world relied solely on Russia to ferry their astronauts to and from space. But that was only temporary as NASA turned to private companies to build its next generation of space taxis in 2014.

Ever since, the agency’s two contractors, SpaceX and Boeing, have worked to build its own version of an astronaut transport. Following a successful uncrewed test flight, SpaceX’s Crew Dragon capsule will be the first to launch astronauts for NASA. If this mission goes well, the California-based spaceflight company will be certified to launch astronauts on a regular basis.
NASA astronaut Shannon Walker has been assigned to the first operational crewed flight of @SpaceX's Crew Dragon, bound for the @space_station!
Pending a successful Demo-2 test, Walker, @Astro_illini, @VicGlover and @Astro_Soichi will launch this year. https://t.co/eYUN1Zt6Y0 pic.twitter.com/Fi4hCEZV3W

It’s first crew of four people — NASA astronauts Michael Hopkins, Victor Glover Jr., and Shannon Walker and Japanese astronaut Soichi Noguchi — are set to fly later this year or the beginning of 2021, if all goes as planned.
Boeing completed its uncrewed test flight in December of last year; however, its capsule experienced an inflight anomaly and was unable to reach the space station. Following an extensive review, Boeing has decided to repeat its uncrewed test flight before it launches people. That flight is expected for some time this fall.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.
