Mars could have a Leap Day like Earth but way more complicated
February 29, “leap day”, is an oddity on the calendar that occurs every four years in an attempt to sync up the Gregorian calendar (the calendar most of the world uses to keep time) with Earth’s rotation around the sun.
One calendar year on Earth is 365 days long; however, the Earth actually takes 365.2422 days to lap the sun. That puts the planet roughly a quarter of a day behind at the end of each year.
To maintain consistency and ensure the seasons line up each year, an extra day was added to the already short month of February — a modification that happens every four years. But even this doesn’t fully solve the problem; additional tweaks are needed.
For instance, if a year is divisible by 100, there’s no extra day — unless the year is divisible by 400. That means that 1700, 1800 and 1900 did not have a leap day, but 2000 did. This adjustment ensures that Earth is as close as possible to the same point in its orbit in consecutive calendar years and keeps our seasons inline.
Unsurprisingly, Earth is not the only planet that needs leap days. The phenomenon could occur on other planets in our solar system as well as those around other stars. That’s because you can’t fit an exact number of spins into one trip around the sun for any planet. There’s usually going to be something left over. Leap days on other worlds, such as Mars, could be more complicated than those here on Earth.
One year on Mars lasts for approximately 668.6 Martian days. (A Martian day is called a sols and equals 24 hours, 39 minutes, and 35.244 seconds.) Future inhabitants might decide that a year on the red planet will be described as 668 days. How do we adjust?
Over the decades, many different ideas for the Martian calendar have been proposed. The most popular one, called the Darian calendar, was created in 1985 by Tomas Gangale.
According to Gangale, the Martian calendar would feature 24 months, each named for the Latin and Sanskrit words for the constellation of the zodiac, like Sagittarius and Dhanus, and so forth. The first five months in each quarter would have 28 Martian days (or sols), with the sixth having only 27. Even-numbered years would total 668 days and odd-numbered years would have 669. The exception to that rule: even-numbered years that were divisible by 10.
Another option was proposed by Michael Allison, a retired NASA scientist. In his version, the Martian calendar would have 668-days divided into 22 months, each totaling 30 or 31 days, similar in fashion to Earth. To make sure the seasons lined up, all years divisible by five will have three leap days, bringing the total to 671.
So which of these calendars do scientists use to keep track of time on Mars? Currently, none.
Instead, they use two systems to keep track of time: one counts the number of Martian days since the start of a mission, and the other keeps track of where Mars was in its orbit at that time.
Right now scientists don’t care if the seasons line up perfectly with the calendar, but that may change when you add humans into the mix. NASA and other space agencies around the world have their sights set on Mars. Once humans land on the red planet and spend significant time there, we are going to need a common calendar to keep track of seasons.

SpaceX successfully launches 100th Starlink mission of 2025
With 100 Starlink missions completed for 2025, space enthusiasts have noted that SpaceX has successfully launched 2,554 Starlink satellites so far this year.
SpaceX achieved its 100th Starlink mission of the year on Friday, October 31, marking another milestone for 2025.
A Falcon 9 rocket carrying 28 Starlink broadband satellites successfully lifted off from Vandenberg Space Force Base in California at 4:41 p.m. ET, carrying another 28 Starlink satellites to Low Earth Orbit (LEO).
Falcon 9 booster’s 29th flight
Roughly 8.5 minutes after liftoff, the Falcon 9’s first stage touched down on the drone ship Of Course I Still Love You in the Pacific Ocean. This marked the booster’s 29th flight, which is approaching SpaceX’s reuse record of 31 missions.
This latest mission adds to SpaceX’s impressive 138 Falcon 9 launches in 2025, 99 of which were dedicated to Starlink, according to Space.com. The company’s focus on reusing boosters has enabled this breakneck pace, with multiple launches each week supporting both Starlink’s expansion and external customers.
Starlink’s network continues massive global expansion
Starlink remains the largest active satellite constellation in history, with more than 10,000 satellites launched, nearly 8,800 of which are currently active. SpaceX recently achieved Starlink’s 10,000-satellite milestone. With 100 Starlink missions completed for 2025, space enthusiasts have noted that SpaceX has successfully launched 2,554 Starlink satellites so far this year.
Starlink, which provides high-speed, low-latency internet connectivity even to the world’s most remote areas, has been proven to be life-changing technology for people across the globe. The service is currently operational in about 150 countries, and it currently has over 5 million subscribers worldwide. From this number, 2.7 million joined over the past year.

Tesla shares updated timeframe for Cybertruck FSD V14 release
The Cybertruck was expected to receive FSD V14 before the end of the month, but Tesla was not able to meet the target.
Tesla’s Full Self-Driving (FSD) V14 update for the Cybertruck could arrive this weekend, as per recent comments from Director of Autopilot Software and VP of AI Ashok Elluswamy.
The Cybertruck was expected to receive FSD V14 before the end of the month, but Tesla was not able to meet the target.
Cybertruck FSD V14
Considering the extended wait for FSD V14, it was no surprise that several Cybertruck owners were asking for updates about the system’s rollout to the all-electric pickup truck on Friday. These included the official Cybertruck X account, which responded to Elluswamy’s end of month estimate with “I only see trick. Where is my treat.”
This prompted a response from the AI executive, who replied with, “Sorry, pushing for early access Cyber release over the weekend.” This means that if all goes well, Cybertruck owners would be able to experience FSD V14 very soon. Some, however, are wondering if Tesla would go straight to V14.2 for the Cybertruck’s FSD V14 update, or if the vehicle will receive V14.1 first.
Tesla pushes to unify FSD experience across its lineup
The upcoming Cybertruck rollout represents the next step in Tesla’s efforts to roll out FSD capabilities across all of its vehicles. FSD V14 is a notable step forward for the company’s AI-driven self driving system, with features like Mad Max mode getting positive reviews from longtime Full Self Driving testers.
For the Cybertruck, the FSD V14 update would mark one of its first major over-the-air upgrades for the vehicle. Likely due to its size, the Cybertruck tends to receive FSD updates later than the S3XY lineup, which is quite surprising considering that the all-electric pickup truck is a premium-priced vehicle that is home to some of Tesla’s most advanced technologies.

“Tesla Ride” program lets riders experience FSD and Grok AI in real-world demos
The initiative aims to bring supervised Full Self-Driving demos and Grok AI-guided experiences to consumers in real world trips.
Tesla has launched a new service designed to make its Full Self-Driving (FSD) technology familiar to all commuters.
Dubbed the “Tesla Ride” program, the initiative aims to bring supervised Full Self-Driving demos and Grok AI-guided experiences to consumers in real world trips.
How Tesla Ride Works
As per the official Tesla Ride website, the session will allow participants to sit in the driver’s seat while a Tesla Advisor rides shotgun as co-pilot. The Tesla Advisor then guides riders through the company’s latest supervised FSD features, comfort settings, and in-car entertainment. Participants would also be able to interact with Grok AI in the vehicles. Grok will be capable of answering questions during the ride, and it will even tell stories along the way.
Tesla noted, however, that Tesla Ride sessions are capped at 45 minutes each, and it requires participants to have a valid driver’s license and insurance. Interested participants are also advised to call beforehand so they can schedule their Tesla Rides.
Marketing push and reach
The Tesla Ride program runs across several markets from October into November, and in some locations into the end of December 2025. Participating states are numerous, from Michigan to Virginia to Illiois, Nevada, and California, among others. A look at the official webpage for Tesla Ride shows that the company is still taking a very cautious approach with the program, with disclaimers clearly stating that FSD Supervised does not make Teslas autonomous just yet.
Tesla’s focus on safety with FSD was highlighted recently by Senior Vice President for Automotive Tom Zhu. “Elon said it in 2021: “For self-driving, even if the road is painted completely wrong and a UFO lands in the middle of the road, the car still cannot crash and still needs to do the right thing.
“The prime directive for the autopilot system is: Don’t crash. That really overrides everything. No matter what the lines say or how the road is done, the thing that needs to happen is minimizing the probability of impact while getting you to your destination conveniently and comfortably,” the executive stated.
