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 Robotaxi just got a big benefit from the U.S. government

The NHTSA is looking to help streamline the application process for companies developing driverless vehicles.

Tesla Robotaxi just got a big benefit from the U.S. Government, as the National Highway Traffic Safety Administration (NHTSA) is looking to ease some rules and streamline the application process that could hinder the development and licensing of autonomous vehicles.

Tesla is set to launch its Robotaxi platform in the coming days or weeks, but regulation on autonomous vehicles is incredibly slim, so automakers are left in a strange limbo as permissions to operate are usually up to local jurisdictions.

The NHTSA still has the ultimate say, but it is now adopting a new strategy that will see companies gain an exemption from federal safety standards and streamline the entire application process.

The agency is authorized to grant exemptions to permit manufacturers to produce vehicles over a two or three-year period that might not comply with certain Federal Motor Vehicle Safety Standards (FMVSS). Robotaxi, for example, will eventually not have a steering wheel or pedals, through the Cybercab that Tesla unveiled last October.

The exemption program the NHTSA announced today would be possible through Part 555 of the National Traffic and Motor Vehicle Safety Act:

“NHTSA may grant a Part 555 exemption if at least one of four bases listed in the statute is met and NHTSA determines that the exemption is consistent with the public interest and the Safety Act. The statute also authorizes NHTSA to subject an exemption to terms the agency deems appropriate and requires that NHTSA publish notice of the application and provide an opportunity to comment.”

The rapid and non-stop innovation that is being performed is tough to keep up with from a legal standpoint. The NHTSA recognizes this and says current legislation is appropriate for traditional vehicles, but not for the self-driving cars companies are producing now:

“The current Part 555 process was designed for traditional vehicles. As currently applied, this process is not well suited for processing exemptions involving ADS-equipped vehicles in a timely manner or overseeing the unique complexities involving their operations. This has resulted in long processing times for applications for ADS-equipped vehicles. NHTSA must improve its Part 555 processing times substantially to keep pace with the rapid innovation of the ADS industry and to ensure that exemptions remain effective tools for nurturing groundbreaking safety technologies.”

Now, the NHTSA will be “enhancing application instructions” to help manufacturers understand the requirements involved in the application process. This will streamline the entire process by “reducing the need for NHTSA to request additional information from the manufacturer,” the agency says.

Next, the NHTSA is going to have a more flexible approach to evaluating exemptions for ADS-equipped vehicles:

“To build flexibility into the Part 555 process while also accounting for the unique aspects of those exemptions, NHTSA intends to develop terms that could be included in Part 555 exemption grants, when appropriate, to condition operations of exempted ADS-equipped vehicles on enhanced and continuing oversight from NHTSA. NHTSA would expect to administer this enhanced oversight through letters, which could be updated over time, mirroring real-world ADS development. This will enable NHTSA to focus its initial review during the application stage and align the Part 555 oversight approach more closely to exemptions administered under NHTSA’s Automated Vehicle Exemption Program (AVEP), which have proven effective for ADS.”

This will benefit any company making autonomous vehicles, but it will especially benefit Tesla in the short-term as it is readying for the launch of Robotaxi.

Tesla is trading up 1.89 percent at the time of publication.

SpaceX has achieved a major milestone, producing its 10 millionth Starlink kit. The accomplishment was celebrated across the company’s Hawthorne, California, and Bastrop, Texas, facilities. 

The milestone was shared in social media by Sujay Soman, Senior Facilities Engineer, in a LinkedIn post, which has since been deleted. 

Starlink Production Ramp

Soman noted in his LinkedIn post that the first 5 million Starlink kits took nearly four years to build, but the next 5 million kits were completed in just 11 months. This underscores SpaceX’s intense efforts to ramp up the satellite internet system’s production, and it reflects the private space company’s manufacturing prowess.

The SpaceX Senior Facilities Engineer shared a couple of photos of the Machine Maintenance and Facilities team in Bastrop to commemorate the event.

“Today, Starlink Product teams across our Hawthorne and Bastrop sites produced the 10th Million Starlink Kit! It took almost 4 years to build our first 5 million kits, and we doubled that in about 11 months. Monumental accomplishment!” Soman wrote in his post.

World-Changing Technology 

The Starlink kits, featuring dish hardware and supporting equipment, enable users to connect to the company’s growing constellation of low Earth orbit satellites. With over 6,000 satellites launched to date, Starlink now provides fast and reliable internet connectivity to over 6 million customers worldwide. This was a significant increase from the 5 million customers that the company reported in February 2025.

SpaceX has not detailed its next production targets, but the production of Starlink’s 10 millionth kit milestone signals the company’s readiness to scale further. Being an Elon Musk-led company, SpaceX is arguably the best in the business when it comes to efficient and cost-effective manufacturing. It would then be unsurprising if SpaceX announces another Starlink production milestone soon.

Tesla has closed a chapter in the saga of the Model S and Model X’s controversial steering yoke. Following the announcement of the new iterations of the flagship vehicles, Tesla promptly removed the steering option for the vehicles’ base variants.

This means that if drivers wish to experience the Model S or Model X with a yoke, they would have to go Plaid.

The new Model S and Model X

The refresh of the Model S and Model X were quite minor, with the two vehicles featuring a new front camera, a new color, and a handful of other small changes like new exterior styling for the Model S Plaid. Tesla also noted on its website that the two vehicles now have a much smoother and quieter ride.

The changes were quite polarizing, with some appreciating the subtle improvements made to the two flagship cars and others arguing that Tesla should have done more. Others, however, noted that the level of improvements implemented on the Model S and Model X would already be considered major refresh for a tech company like Apple.

No More Yoke Unless Plaid

When Tesla refreshed the Model S and Model X in 2021, the vehicles were released with a steering yoke as standard. The yoke was controversial, with critics stating that it was unsafe and fans stating that it made driving the Model S and Model X fun. Tesla later introduced a round steering wheel option for the Model S and Model X, which later became standard on the two flagship vehicles.

This remains true today, with the most recent versions of the Model S and Model X still being released with a round steering wheel as standard. Those who wish to experience the Model S and Model X Plaid as envisioned by the company and its CEO, Elon Musk, however, might find it a good idea to spend the extra $1,000 for the vehicles’ yoke steering wheel.
