The month of the robotic invasion of Mars is upon us. Seven months ago, the United States, China, and the United Arab Emirates launched missions on a 300 million mile (480 million kilometer) journey to Mars.

Last week, two of the three missions quietly arrived and inserted themselves into Mars orbit. The final spacecraft to arrive, NASA’s Mars 2020 Perseverance mission, however, will not go gently into the Martian atmosphere. On Thursday, February 18, NASA’s latest Mars mission destined to uncover evidence of ancient microbial life on the distant planet is set to touchdown following a spectacular display of extremely complex engineering.

Getting to Mars

Launching to the Red Planet is a strategic maneuver that can only be completed once every two years. This is due to the varying speeds and the elliptical shape of the planets’ orbits around the sun. The point at which Earth and Mars are aligned close enough to minimize travel time, called an opposition, occurs only once every two years.

The most recent opposition occurred in July 2020. Four international Mars missions were intended to leave Earth that summer, however, due to required further certification of parachutes the European Space Agency’s ExoMars Rosalind Franklin rover would have to wait for its launch opportunity during the next planetary opposition to occur in 2022. That left three robotic invaders from the United States, the United Arab Emirates, and China to escape Earth’s orbit and become interplanetary superstars.

Hope arrives to Mars

The United Arab Emirates Space Agency’s first-ever interplanetary mission, a spacecraft named Al-Amal, or the Hope Probe, was developed in collaboration between the Mohammed bin Rashid Space Center,  Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder, Arizona State University, and the Space Sciences Lab at the University of California, Berkeley. It was launched on July 19, 2020, from Tanegashima Space Centre in Japan aboard an H2A202 rocket. On Tuesday, February 9, the Hope Probe was the first of the three missions to complete the journey to Mars and successfully insert itself into orbit.

The Hope Probe arrived to near-Mars orbit traveling approximately 75,000 mph (121,000 kph), far too fast to successfully achieve a safe Martian orbital insertion maneuver. In order to slow down to the approximate 11,000mph (18,000 kph) needed to be captured by Mars orbit, the spacecraft had to autonomously fire its main thrusters and perform a Mars Orbit Insertion burn lasting an agonizing 27 minutes. To compensate in the instance of a thruster failure, there was a backup safety protocol that would’ve doubled the length of the burn. After 27 grueling minutes, the Mohammad Bin Rashid Space Center located in Dubai reported that the maneuver was completed successfully and the Hope Probe had arrived at its final destination.

Unlike the American and Chinese missions to Mars which will land rovers on the surface, the United Arab Emirates’ Hope Probe will remain in Mars orbit for the duration of its mission – approximately two Martian years. The spacecraft is equipped with a suite of three instruments, two spectrometers – one infrared and one ultraviolet – to study the Martian atmosphere, and one imager to capture high-resolution images to study the surface from afar.

China’s Tianwen-1 Rover will hang out in orbit before landing in May

The same type of Mars Orbit Insertion maneuver was completed by China’s first interplanetary mission, the Tianwen-1 spacecraft. Launched from China on July 23, 2020, Tianwen-1 arrived at Mars orbit just one day after the Hope Probe on Wednesday, February 10.

The Tianwen-1 spacecraft had to autonomously complete an excruciating 11-minute “braking” burn to slow down which took it behind the planet as it was captured by Mars gravity and entered into orbit.

Like NASA’s Perseverance, the Tianwen-1 mission features a rover that will eventually land on the surface of Mars. The process to get the rover to the surface, however, varies from that of NASA’s Mars 2020 Perseverance mission.

The Tianwen-1 spacecraft is made of two components, an orbiter and a rover. Currently, it is planned that the orbiter will spend some time in Mars orbit for a period of comprehensive observation before attempting a landing of the rover in May. Ideally, the spacecraft will then touch down in a region known as Utopia Planitia.

Once the rover safely makes it to the surface it will initiate the investigation period of the mission. The rover carries a suite of scientific instruments that will be used to investigate the composition of the Martian surface searching for the potential distribution of water and ice. Similar to China’s Yutu 2 rover which is exploring the Moon, the Tianwen-1 rover also carries a panoramic camera to image the planet.

Perseverance and Ingenuity like no other

The last of the three Mars missions – NASA’s Mars 2020 Perseverance mission launched on July 30, 2020, from Cape Canaveral Space Force Station aboard a United Launch Alliance Atlas 5 rocket. As far as Mars arrivals go, the best has certainly been saved for last. Following the success of the other two missions from China and the United Arab Emirates, the stage is set for Perseverance to make its dramatic entrance.

NASA’s Mars 2020 Perseverance mission is by far the most ambitious mission to launch to Mars during the 2020 planetary transfer window. NASA is not attempting to land one, but two spacecraft on the surface of Mars. The $2.4 billion Mars 2020 mission is comprised of the Perseverance rover – powered by the heat produced by radioactive decay of Plutonium – and a first of its kind rotary helicopter called Ingenuity. It is scheduled to arrive in dramatic fashion on Thursday, February 18.

Rather than conducting a braking maneuver to slow down and enter Mars orbit, the Perseverance spacecraft will autonomously conduct the entry, descent, and landing (EDL) procedure – essentially going from traveling several thousand miles an hour to descending slowly under a parachute canopy to softly land in mere minutes.

The spacecraft – housed in a protective aeroshell with its robust heat shield facing the planet’s surface – will burst into Mars’ atmosphere traveling nearly 12,500 mph (20,000 kph). Once through, Pesevereance will ditch its heat shield and autonomously begin scanning the Martain terrain to determine its relative location and make adjustments to find an optimal landing spot. Then, a powered descent module will deploy transporting the rover the rest of the way down slowing to less than 2mph (3kph). Finally, the descent module will hover and deploy a complex harness system lowering Perseverance – and its stowaway, the Ingenuity helicopter – to the Martian surface for touchdown.

After seven months of interplanetary travel, it all comes down to the final seven minutes – the length of time the EDL process is expected to take. All spacecraft controllers back on Earth can do is watch and wait for that final telemetry reading indicating that Perseverance has successfully touched down. That is why this process has earned the nickname “seven minutes of terror.”

Beginning around 11:15 am PST (19:15 UTC) on Thursday, February 18th, NASA will provide live coverage of Perseverance’s landing attempt. The agency will carry the coverage on NASA TV and its website, as well as a number of other platforms including YouTube, Twitter, Facebook, LinkedIn, Twitch, Daily Motion, Theta.TV, and NASA App.

Tesla Semi gets its largest order yet

Published

Credit: Einride

Tesla got its largest order for the all-electric Class 8 Semi yet, a 500-unit order from Einride AB, a Swedish trucking company.

Einride made the announcement this morning following its second-quarter earnings call. The company said it plans to use 500 Tesla Semi units on its fleet intelligence platform, called Saga AI. The deployments will serve large companies like Amazon and will extend Einride’s electric freight network across logistics routes in California, New Jersey, Texas, Illinois, and Georgia.

The deployment is being carried out in several phases over the next two years as Tesla ramps production of the Semi at its dedicated production facility in Sparks, Nevada. Einride will receive its first Semi units in September.

Saga AI

Saga AI is Einride’s dedicated fleet intelligence platform. It enables scaled adoption of electric trucks for freight use and allows shippers to integrate electric capacity without the operational burden or capital risks of managing a fleet. This helps integrate cost-efficient logistics and makes budgeting and forecasting much more accurate.

Tesla Semi’s Adoption

The Tesla Semi is now gathering large-scale clients past those who have helped the company operate a Pilot Program to gain initial information and feedback from real-world drivers.

Perhaps the biggest and most notable is that of Frito-Lay and PepsiCo., who have worked with Tesla for the past several years to dial in the finer details of the truck, including its efficiency and operation-related components.

Tesla Semi gets strange-but-understandable comparison from Jay Leno

There has been tremendous progress in that time, and it even catalyzed Tesla to make some design changes, which were unveiled earlier this year.

But Einride CEO Roozbeh Charli says his company’s partnership with Tesla will continue to push those things forward:

“This deployment is yet another proof point that we can execute at the scale our customers demand. Working closely with Tesla to bring next-generation Semis into active operations quickly and at scale is a testament to the strength of that partnership, and how quickly this technology is maturing from promise to daily operations.”

Tesla Semi is already winning over truck drivers

Additionally, Dan Priestley, the Director of the Semi Program at Tesla, said the partnership is ideal due to Einride’s focus on sustainable transport:

“Einride is at the forefront of sustainable freight, and we are thrilled to deepen our relationship with them through this order of 500 Semis. EV heavy trucks provide lower costs per mile from fuel savings, reduced maintenance, and better uptime over diesel trucks. These savings increase further through operational efficiency when deploying EV trucks at scale, and we are excited that Einride recognizes this and look forward to supporting their deployments.”

India tells Elon Musk’s X to “Follow the Law” in latest censorship update

Elon Musk says X now exposes government censorship, but India’s secrecy laws complicate that promise.

Published

By

Elon Musk’s promise to make government censorship requests on X “clearly visible” is running into a wall in India, where the law forbids the very disclosure Musk is promising.

On August 15, Musk responded to an update from X’s open-source algorithm team by writing “Any censorship required by governments is now clearly visible.” The claim referred to a change X pushed two days earlier to its public xai-org/x-algorithm repository, which now includes a controversial filter written directly into the code. The filter suppresses posts from 665 accounts flagged by Brazil’s Superior Electoral Court from appearing in the For You feed of any viewer located in Brazil, unless the viewer already follows the account. The election tied to the filter is scheduled for October 4.

India’s government wasn’t as impressed, and responded on Monday that “X will have to follow the law of the land,” in response to Musk’s transparency push covered by the Times of India. The problem is structural rather than political. India issues content blocking orders under Section 69A of its IT Act, and Rule 16 of the accompanying 2009 Blocking Rules requires those orders to stay confidential. Publishing an India equivalent of the Brazil filter, naming specific accounts and citing specific government orders, would itself violate Indian law. Government use of Section 69A has grown from roughly 6,000 orders a year between 2018 and 2023 to about 24,300 in 2025, according to a Tech Times report.

Elon Musk shares details on X vs. Brazil conflict

The contrast puts Musk’s transparency pledge in an odd spot. It works largely as advertised in Brazil, where electoral law requires disclosure and X can point to specific account IDs and a specific court order in public code. It cannot work the same way in India, where the law requires the opposite. X users in India will keep seeing content disappear from search and their feeds without any public accounting of why, even as X tells the rest of the world that its censorship compliance is now inspectable.

This isn’t the first time X’s fights with a national government have shaped how the platform operates. Brazil’s Supreme Court ordered X to suspend the accounts of sitting lawmakers and journalists in 2024, a standoff that cost X its Brazilian revenue for months and froze Starlink’s local accounts before the investigation into Musk and X was closed in March with no evidence of wrongdoing found. X also sued California over a state law requiring moderation disclosures, arguing the mandate itself violated the First Amendment.

Whether India’s government pursues anything beyond a public statement remains to be seen. For now, the mismatch between what X can legally publish and what different governments legally allow it to publish is the real story behind Musk’s seven word claim.

Tesla Cybercab launch preparations have begun

Published

Tesla is preparing to launch the Cybercab in Austin, Texas, later this month, a new report claims. Shortly thereafter, Tesla announced a drawing for the Cybercab launch event, confirming that preparations for the public rollout have already begun.

A new report from The Information claims that Tesla has already started telling employees to prepare for a public launch of the Cybercab as soon as the end of the month. The vehicle will launch publicly to riders in Austin initially.

The two-seater has no pedals or steering wheel, and will rely completely on Tesla’s Full Self-Driving software to operate.

While the report went unconfirmed from Tesla, the company launched a lottery to ride in a Cybercab at an upcoming launch event, essentially confirming that preparations are underway:

Cybercab entered production at Gigafactory Texas back in April, with initial units being test mules for the company as it has put the car in a variety of environments and climates. Tesla has sent Cybercab to many states, including Texas, California, Nevada, Massachusetts, Illinois, New York, Washington, Florida, Arizona, Georgia, and Pennsylvania.

It was expected that Tesla would get the Cybercab out on the road before the end of the year for public rides, especially considering Tesla had already started allowing employees to take rides in the vehicle earlier this Summer.

Tesla starts testing its Starlink-integrated Cybercab on public roads

This is a huge development, not only with the Cybercab program, but for Tesla’s self-driving program. Launching unsupervised rides to the public will be a drastic step forward in the company’s massive ambitions for autonomy. It is a long time coming, too. Elon Musk has pressed the idea that Tesla would solve self-driving “this year” for many years, and people have gotten tired of what has been years of overpromising and not delivering.

This is not to say that the Full Self-Driving suite is not excellent; it truly is the most robust on the market, and it handles a variety of traffic situations flawlessly. It definitely has its faults, but generally, it is fantastic.

Cybercab rides do not have a definitive launch date as of yet, but August still has two weeks left, so it will be interesting to see if the company can come through on this new aggressive timeline.
