A Tale of Two Rovers: How does Mars 2020 compare to Curiosity?
NASA’s next Mars rover is almost ready to launch. Engineers recently took it for a test spin, before shipping it off to its Cape Canaveral launch site. The six-wheeled rover will blast off this July; once it arrives on Mars, it will scour the red planet for signs of ancient life.
The Mars 2020 rover, which should receive a name very soon, is nearly identical in appearance to its predecessor, the Curiosity rover. After landing on Mars in 2012, Curiosity has spent its time exploring Gale Crater, a 96-mile-wide crater.
It was once the site of an ancient lake and stream system; scientists believe that it may have been able to support life. However, like the rest of the planet’s surface, the area is dry today.
The twin rovers, Spirit and Opportunity landed on Mars in 2004 with one major goal: to follow the water. Right out of the gate, the duo proved that water once flowed on the surface of Mars. But what happened to it?
To answer that question, NASA launched the supersized Curiosity rover to learn more. Since landing in 2012, Curiosity discovered that Gale Crater was once home to an ancient lake billions of years ago and that it could have supported microbial life. The rover is still scouring the crater, hunting for clues as it climbs Mount Sharp, a 3-mile-tall (5-kilometer-tall) peak within the crater — that scientists believe was partially formed by water.
3,760 miles (6,050 kilometers) away, Mars 2020 will explore Jezero Crater, the site of an ancient delta. Here the rover will take the next scientific step: It will look for actual signs of past life, called biosignatures, by analyzing samples of rocks and soil. It will also bag up samples that could be retrieved by future missions and eventually returned to Earth for more in-depth analysis.
Mars 2020 is essentially a souped-up version of the Curiosity rover, but charged with searching for signs of life and collecting samples for eventual return to Earth. The new rover is estimated to cost $1.9 billion dollars and will carry a suite of 7 specialized instruments that will science the hell out of Mars.
But first the rover has to land on Mars. To do so, it must survive a harrowing process known as entry, descent, and landing (aka seven minutes of terror).
To the untrained eye, Mars 2020 looks like an identical copy of Curiosity, but if you look closely, you can tell that the two apart. Building a rover from scratch is extremely difficult and expensive. The folks at NASA built on the success of Curiosity and added new capabilities. A process that enabled more science at a reduced cost.
The beefier Mars 2020 rover is about 280 lbs. (127 kilograms) heavier than its counterpart. That’s because it carries different tools, like a larger drill. This enables the new rover to drill into rocks, extracting rock cores rather than just smashing them.
We all love the epic robot selfies and stunning views of Martian landscapes so of course the new rover will be packing multiple cameras. Curiosity is equipped with 17 cameras; by comparison, Mars 2020 will have 23 that will shoot mostly in color. Additionally, Mars 2020’s Mastcam-Z will film in high definition and be able to zoom.
Mars 2020 will also carry not one but two microphones on its journey so all of us back here on Earth can hear what Mars sounds like. The microphones will record the rover’s landing on Mars, as well as the Martian wind and will listen as the rover zaps scientific targets with its on board laser.
Another design improvement will be the wheels. Curiosity was equipped with aluminum wheels, which have been badly beaten up by the rugged Martian terrain. Sharp rocks have proved to be troublesome, with NASA modifying the rover’s driving plan to ensure Curiosity makes it through its mission. To avoid these kinds of issues, engineers made Mars 2020’s wheels more robust.
“Extensive testing in JPL’s Mars Yard has shown these treads better withstand the pressure from sharp rocks but work just as well on sand,” NASA officials said in a news release.
NASA plans to return to the moon and eventually send humans to Mars. To that end, the Mars 2020 rover will help pave the way for future missions. The rover will carry spacesuit samples to determine how they degrade over time, as well as a subsurface radar instrument that could potentially be used to find buried water ice.
Additionally, an oxygen generator will test technology that future astronauts could use to make their own rocket fuel from the Martian atmosphere.

Starlink gets its latest airline adoptee for stable and reliable internet access
The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.
SpaceX’s Starlink, the satellite internet program launched by Elon Musk’s company, has gotten its latest airline adoptee, offering stable and reliable internet to passengers.
Southwest Airlines announced on Wednesday that it would enable Starlink on its aircraft, a new strategy that will expand to more than 300 planes by the end of the year.
The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.
Tony Roach, Executive Vice President, Chief Customer and Brand Officer for the airline, said:
“Free WiFi has been a huge hit with our Rapid Rewards Members, and we know our Customers expect seamless connectivity across all their devices when they travel. Starlink delivers that at-home experience in the air, giving Customers the ability to stream their favorite shows from any platform, watch live sports, download music, play games, work, and connect with loved ones from takeoff to landing.”
Southwest also said that this is just one of the latest upgrades it is making to provide a more well-rounded experience to its aircraft. In addition to Starlink, it is updating cabin designs, offering more legroom, and installing in-seat power to all passengers.
Southwest became one of several airlines to cross over to Starlink, as reviews for the internet provider have raved about reliability and speed. Over the past year, Hawaiian Airlines, United Airlines, Alaska Airlines, airBaltic, Air France, JSX, Emirates, British Airways, and others have all decided to install Starlink on their planes.
This has been a major move away from unpredictable and commonly unreliable WiFi offerings on planes. Starlink has been more reliable and has provided more stable connections for those using their travel time for leisure or business.
Jason Fritch, VP of Starlink Enterprise Sales at SpaceX, said:
“We’re thrilled to deliver a connectivity experience to Southwest Airlines and its Customers that really is similar, if not better, than what you can experience in your own home. Starlink is the future of connected travel, making every journey faster, smoother, and infinitely more enjoyable.”
Starlink recently crossed a massive milestone of over 10 million subscribers.
Despite many recent rumors and various reports, Elon Musk confirmed today that SpaceX is not developing a phone based on Starlink, not once, but twice.
Today’s report from Reuters cited people familiar with the matter and stated internal discussions have seen SpaceX executives mulling the idea of building a mobile device that would connect directly to the Starlink satellite constellation.
Musk did state in late January that SpaceX developing a phone was “not out of the question at some point.” However, He also said it would have to be a major difference from current phones, and would be optimized “purely for running max performance/watt neural nets.”

While Musk said it was not out of the question “at some point,” that does not mean it is currently a project SpaceX is working on. The CEO reaffirmed this point twice on X this afternoon.
Musk said, “Reuters lies relentlessly,” in one post. In the next, he explicitly stated, “We are not developing a phone.”

Musk has basically always maintained that SpaceX has too many things going on, denying that a phone would be in the realm of upcoming projects. There are too many things in the works for Musk’s space exploration company, most notably the recent merger with xAI.
SpaceX officially acquires xAI, merging rockets with AI expertise
A Starlink phone would be an excellent idea, especially considering that SpaceX operates 9,500 satellites, serving over 9 million users worldwide. 650 of those satellites are dedicated to the company’s direct-to-device initiative, which provides cellular coverage on a global scale.
Nevertheless, there is the potential that the Starlink phone eventually become a project SpaceX works on. However, it is not currently in the scope of what the company needs to develop, so things are more focused on that as of right now.
With the news of a merger between SpaceX and xAI being confirmed earlier this week by CEO Elon Musk directly, the first moves of an umbrella company that combines all of the serial tech entrepreneur’s companies have been established.
The move aims to combine SpaceX’s prowess in launches with xAI’s expanding vision in artificial intelligence, as Musk has detailed the need for space-based data centers that will require massive amounts of energy to operate.
It has always been in the plans to bring Musk’s companies together under one umbrella.
“My companies are, surprisingly in some ways, trending toward convergence,” Musk said in November. With SpaceX and xAI moving together, many are questioning when Tesla will be next. Analysts believe it is a no-brainer.
SpaceX officially acquires xAI, merging rockets with AI expertise
Dan Ives of Wedbush wrote in a note earlier this week that there is a “growing chance” Tesla could be merged in some form with the new conglomeration over the next 12 to 18 months.
“In our view, there is a growing chance that Tesla will eventually be merged in some form into SpaceX/xAI over time. The viewis this growing AI ecosystem will focus on Space and Earth together… and Musk will look to combine forces,” Ives said.
Let’s take a look at the potential.
The Case for Synergies – Building the Ultimate AI Ecosystem
A triple merger would create a unified “Musk Trinity,” blending Tesla’s physical AI with Robotaxi, Optimus, and Full Self-Driving, SpaceX’s orbital infrastructure through Starlink and potential space-based computer, and xAI’s advanced models, including Grok.
This could accelerate real-world AI applications, more specifically, ones like using satellite networks for global autonomy, or even powering massive training through solar-optimized orbital data centers.

This would position the entity, which could ultimately be labeled “X,” as a leader in multiplanetary AI-native tech.
It would impact every level of Musk’s AI-based vision for the future, from passenger use to complex AI training models.
Financial and Structural Incentives — and Risks
xAI’s high cash burn rate is now backed by SpaceX’s massive valuation boost, and Tesla joining the merger would help the company gain access to private funding channels, avoiding dilution in a public-heavy structure.
The deal makes sense from a capital standpoint, as it is an advantage for each company in its own specific way, addressing specific needs.
Because xAI is spending money at an accelerating rate due to its massive compute needs, SpaceX provides a bit of a “lifeline” by redirecting its growing cash flows toward AI ambitions without the need for constant external fundraising.
Additionally, Tesla’s recent $2 billion investment in xAI also ties in, as its own heavy CapEx for Dojo supercomputers, Robotaxis, and Optimus could potentially be streamlined.
Musk’s stake in Tesla and SpaceX, after the xAI merger, is also uneven. His ownership in Tesla equates to about 13 percent, only increasing as he achieves each tranche of his most recent compensation package. Meanwhile, he owns about 43 percent of the private SpaceX.
A triple merger between the three companies could boost his ownership in the combined entity to around 26 percent. This would give Musk what he wants: stronger voting power and alignment across his ventures.
It could also be a potential facilitator in private-to-public transitions, as a reverse merger structure to take SpaceX public indirectly via Tesla could be used. This avoids any IPO scrutiny while accessing the public markets’ liquidity.
Timeline and Triggers for a Public Announcement
As previously mentioned, Ives believes a 12-18 month timeline is realistic, fueled by Musk’s repeated hints at convergence between his three companies. Additionally, the recent xAI investment by Tesla only points toward the increased potential for a conglomeration.
Of course, there is speculation that the merger could happen in the shorter term, before June 30 of this year, which is a legitimate possibility. While this possibility exists but remains at low probability, especially when driven by rapid AI/space momentum, longer horizons, like 2027 or later, allow for key milestones like Tesla’s Robotaxi rollout and Cybercab ramp-up, Optimus scaling, or regulatory clarity under a favorable administration.

The sequencing matters: SpaceX-xAI merger as “step one” toward a unified stack, with a potential SpaceX IPO setting a valuation benchmark before any Tesla tie-up.
Full triple convergence could follow if synergies prove out.
Prediction markets are also a reasonable thing to look at, just to get an idea of where people are putting their money. Polymarket, for example, sits at between a 12 and 24 percent chance that a Tesla-SpaceX merger is officially announced before June 30, 2026.
Looking Ahead
The SpaceX-xAI merger is not your typical corporate shuffle. Instead, it’s the clearest signal yet that Musk is architecting a unified “Muskonomy” where AI, space infrastructure, and real-world robotics converge to solve humanity’s biggest challenges.
Yet the path is fraught with execution risks that could turn this visionary upside into a major value trap. Valuation mismatches remain at the forefront of this skepticism: Tesla’s public multiples are unlike any company ever, with many believing they are “stretched.” On the other hand, SpaceX-xAI’s private “marked-to-muth” pricing hinges on unproven synergies and lofty projects, especially orbital data centers and all of the things Musk and Co. will have to figure out along the way.
Ultimately, the entire thing relies on a high-conviction bet on Musk’s ability to execute at scale. The bullish case is transformative: a vertically integrated AI-space-robotics giant accelerates humanity toward abundance and multi-planetary civilization faster than any siloed company could.
