NASA’s most ambitious – and difficult – Mars rover mission to date is nearly at the end of its interplanetary journey, but it is just the beginning of the excitement. On Tuesday (Feb. 16) engineers at NASA’s Jet Propulsion Laboratory (JPL) confirmed that Perseverance is doing well and is prepared to attempt a touchdown at about 12:55 p.m. PST (3:55 p.m. EST) on Thursday (Feb. 18).

NASA’s fifth Mars rover, Perseverance, will attempt a tried and true, but terrifying landing method to reach the Martain surface safely. In a process called entry, descent, and landing (EDL) the rover will burst through the Martian atmosphere at 12,500mph (20,000 kph) and slow to just under 2mph (3kph) in about seven minutes – a process which has earned the nickname “seven minutes of terror.”

From interplanetary spacecraft to Martian rover in seven minutes

For the past seven months, Perseverance has traveled 300 million miles (480 million kilometers) as an interplanetary spacecraft. When it reaches its final destination of Mars on Feb. 18, the spacecraft will have to shed some layers to prepare to land on the Martian surface. Perhaps the most challenging part of the seven minutes of terror is that Perseverance will conduct every aspect autonomously – engineers back on Earth will not be able to intervene due to the communications time delay caused by the distance between Earth and Mars.

During the first stage of landing known as entry, Perseverance will slam into the relatively thin Martian atmosphere at the neck-break speed of 12,500mph (20,000 kph). At approximately 12:38 p.m. PST (3:38 p.m. EST), 10 minutes prior to entering the Martian atmosphere, the Cruise Stage which has reliably propelled Perseverance on its journey from Earth via solar power will separate. This will initiate the official transition from spacecraft into rover.

To protect the rover and its critical hardware Perseverance is housed inside of a protective covering – called an aeroshell – and is outfitted with a robust heat shield. Small thrusters at the crown of the aeroshell help to reorient itself and ensure that the heat shield is facing in the right direction as it enters the atmosphere. The aeroshell and heatshield will absorb and deflect the brunt of the heat energy – reaching about 2,370 degrees Fahrenheit (about 1,300 degrees Celsius) – caused by the friction of entering the Martian atmosphere at such a high velocity.

Once through peak heating and deceleration, Perseverance will utilize a new technology called Range Trigger to determine its exact location and distance to the surface. The spacecraft will utilize this technology to autonomously determine the optimal time to deploy its supersonic parachute – the largest ever sent to Mars – and separate its heat shield. This is expected to occur at 12:52 p.m. PST (3:52 p.m. EST). Once the heat shield has separated the powered descent stage – and the Perseverance rover itself – will be exposed to the Martian environment.

Although a similar descent method has been used in the past with the landing of NASA’s Curiosity rover in 2012, Perseverance’s way of doing things has received a major upgrade.

Once the heat shield has been dispersed, Perseverance will use a radar and cameras to utilize a new landing technology called Terrain-Relative Navigation. Essentially, Perseverance will continuously take images to map out the Martian surface as it descends to determine its exact location. The spacecraft will actively decide and target the best possible safe landing site which can be autonomously changed up to 2,000 feet (600 meters). Then the aeroshell and parachute are jettisoned and it’s the powered descent module’s time to shine.

Using rockets to land, rather than to launch

Just two minutes after ditching the heat shield, at 12:54 p.m. PST (3:54 p.m. EST) and only 1.3 miles (2.1 kilometers) above the surface, the powered descent stage will fire eight throttleable retrorockets to slow the spacecraft’s descent even more and steer it to its chosen landing target. During the powered descent phase, the spacecraft will slow from about 190 mph (306 kph) to just 1.7 mph (2.7 kph).

Once the spacecraft determines that it is 65 feet (20 meters) from the surface by utilizing the Terrain-Relative Navigation, the powered descent stage will initiate the sky crane maneuver. In this phase, the Perseverance rover will be delicately lowered to the Martian surface with a system of Nylon cords.

At 12:55 p.m. PST (3:55 p.m. EST) the $2.4 billion NASA Mars 2020 mission will officially touchdown on the surface of Mars in the Jezero Crater. Once safely down, the sky crane will severe the cords and fly off for a crash landing at a safe distance away from the rover.

During the landing attempt, NASA’s Mars Reconnaissance Orbiter will be overhead and constantly sending telemetry back to Earth via NASA’s Deep Space Network. The telemetry will indicate to engineers back at NASA JPL if the landing procedure was successful and will confirm a touchdown at 12:55 p.m. PST (3:55 p.m. EST).

This will be the first time that a NASA Mars rover will be landing with its eyes open, so to speak. NASA hopes that the first images – and sounds – of the Martian landing will be available to release to the public within about an hour of confirmed touchdown.

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 the NASA app. You can view the entry, descent, and landing process in its entirety in the video below provided by NASA’s JPL.

Tesla snags Lamborghini alum to help in newly entered market

Published

Tesla has snagged a Lamborghini alum to help with its entrance into a new market, which has proven to be an intricate situation for the automaker.

A report from Bloomberg states that Tesla has hired Sharad Agarwal, who was formerly employed by the Italian luxury carmaker, to run its operations in India. With Lamborghini, he was employed to handle operations in India.

Tesla launches in India with Model Y, showing pricing will be biggest challenge

Tesla has gone through quite a few different team members with its launch in India, starting with a few hirings a few years ago, well before the company actually committed to selling cars in the country.

The move helps Tesla streamline its executive decision-making process, as it previously had employees in India reach out to managers based in China, among other areas. Agarwal will be stationed in India and will handle the company’s operations.

Tesla’s mentality behind the strategy is to have local leadership, something that seems to cater to the market specifically.

Tesla had previously put Isabel Fan, the manager of Southeast Asia for the company, in the position. However, Tesla seemed to want someone who was more permanent and would be dedicated to India exclusively.

India has the largest population on Earth and has a massive automotive market for that reason. Tesla stands to gain a lot from a strong performance in India, and its clean energy vehicles could help with pollution of all kinds in the region.

Tesla’s path to entrance in the Indian market was a long one, as the company tried for nearly ten years to get into the elusive region. Back in 2016, CEO Elon Musk said Tesla “would love to be in India,” teasing the Model 3.

By 2017, Tesla had met with officials from the country, but tried to get import duties down to nothing from 100 percent.

Indian authorities denied Tesla’s request.

For years, Musk met with Prime Minister Narendra Modi to try and iron out a deal of some sort. Nothing truly came to fruition, at least until last year, when real movement started.

By 2024, India had introduced a strategy to reduce import duties for some companies, which was enough for Tesla to make a move. It is now 2025, and the company still has not committed to building a factory in the region. However, it is not completely out of the question.

Tesla Sentry Mode helps lock up drive-by shooting suspect in Seattle

“A nearby Tesla actually captured the video that showed a man crouched behind a vehicle firing gunshots. A lot of vehicles record, and officers know that Teslas, especially, record, so we use that video all the time in these instances.”

Police in Seattle, Washington, are crediting Tesla’s well-known Sentry Mode for helping find a suspect in a drive-by shooting case.

A 21-year-old was arrested for an alleged drive-by shooting in the Pioneer Square neighborhood of Seattle this past Sunday, and the leads on the case seemed to be slim.

However, a Tesla parked nearby was able to record the shooting, as well as the car that the suspect hopped in after the crime occurred. It helped police identify the person they were looking for.

Seattle Police Department Detective Brian Pritchard said to MyNorthwest that the Tesla was a critical part of finding the suspect and placing him under arrest:

“A nearby Tesla actually captured the video that showed a man crouched behind a vehicle firing gunshots. A lot of vehicles record, and officers know that Teslas, especially, record, so we use that video all the time in these instances.”

The Tesla footage helped the Police put the suspect into handcuffs about an hour after the crime was committed. They are currently charged with drive-by shooting and unlawful possession of a firearm.

Tesla Sentry Mode is a security feature the vehicle utilizes to help solve crimes like vandalism, but it is also a cool feature that has caught things like accidents and other incidents on camera.

Many people still do not know about it, including the many vandals who keyed or broke the windows of Teslas earlier this year, as people damaged others’ cars in an act of retaliation against CEO Elon Musk when he became involved in politics.

This is far from the first time Sentry Mode has helped Police Departments solve crimes. Last September, we reported on Oakland’s Police Department in California using Teslas near crime scenes to help solve cases.

Tesla Sentry Mode is Oakland PD’s secret weapon against rising crime

Sergeant Ben Therriault, president of the Richmond Police Officers Association, said, “We have all these mobile video devices floating around,” in reference to the Teslas that sit and capture nearly everything that surrounds them.

Sentry Mode has helped officers arrest a variety of suspects, including several people who were allegedly involved in the murder of a 27-year-old woman in Northern California.

Update: 4:00 p.m. EDT – Charles Schwab has reached out to TESLARATI with the following statement, clarifying that it plans to vote FOR Musk’s compensation package:

“Schwab Asset Management’s approach to voting on proxy matters is thorough and deliberate. We utilize a structured process that focuses on protecting and promoting shareholder value. We apply our own internal guidelines and do not rely on recommendations from Glass Lewis or ISS. In accordance with this process, Schwab Asset Management intends to vote in favor of the 2025 CEO performance award proposal. We firmly believe that supporting this proposal aligns both management and shareholder interests, ensuring the best outcome for all parties involved.”
There have also been updates to the headline and various paragraphs to reflect this as well as accuracy.

Tesla investors are pushing Charles Schwab for clarification after it was expected to vote against CEO Elon Musk’s pay package.

Several high-profile Tesla influencers are speaking out against Charles Schwab, saying its decision to vote against the plan that would retain Musk as CEO and give him potentially more voting power if he can achieve the tranches set by the company’s Board of Directors.

The Tesla community appeared to see that Schwab is one firm that tends to vote against Musk’s compensation plans, as they also voted against the CEO’s 2018 pay package, which was passed by shareholders but then denied by a Delaware Chancery Court.

Schwab’s move was recognized by investors within the Tesla community and now they are speaking out about it:

At least six of Charles Schwab’s ETFs were expected to vote against Tesla’s Board recommendation to support the compensation plan for Musk. The six ETFs represent around 7 million Tesla $TSLA shares.

Jason DeBolt, an all-in Tesla shareholder, summarized the firm’s decision really well:

As a custodian of ETF shares, your fiduciary duty is to vote in shareholders’ best interests. For a board that has delivered extraordinary returns, voting against their recommendations doesn’t align with retail investors, Tesla employees, or the leadership we invested to support. If Schwab’s proxy voting policies don’t reflect shareholder interests, my followers and I will move our collective tens of millions in $TSLA shares (or possibly hundreds of millions) to a broker that does, via account transfer as soon as this week.”
Tesla shareholders will vote on Musk’s pay package on Thursday at the Annual Shareholders Meeting in Austin, Texas.

It seems more likely than not that it will pass, but investors have made it clear they want a decisive victory, as it could clear the path for any issues with shareholder lawsuits in the future, as it did with Musk’s past pay package.
