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.

Elon Musk follows Trump’s lead, says a SpaceX name change is coming
Elon Musk says SpaceXAI will become SpaceXSI, marking its second rebrand in under three months.
Elon Musk wants to rename his artificial intelligence company again, less than three months after its last rebrand.
In a string of posts on X early Sunday morning, Musk wrote “No more AI,” followed by “SI” and “It’s better.” He then added, “SpaceX is a super intelligence company.” When a user asked whether SpaceXAI could become SpaceXSI, Musk replied, “Yes, we will make that change.”
The posts extend a terminology push that began at the White House last week. On September 29, President Donald Trump signed an executive order directing federal agencies to replace “artificial intelligence” and “AI” with “Super Intelligence” and “SI” on government websites, policy documents and press releases. The same day, Musk sat beside Trump as the heads of the largest AI companies signed a voluntary safety accord, as Teslarati reported. Speaking to reporters afterward, Musk caught himself mid sentence: “I think it is worth highlighting the positive benefits of A.I. … S.I., pardon me.”
Elon Musk and Trump are closer than ever, and Tesla could be the big winner
SpaceXSI would be the third name for the business since February. SpaceX acquired xAI on February 2 in a deal that valued the combined company at $1.25 trillion. In May, Musk said xAI would be dissolved as a separate company, and on July 6 the division adopted the SpaceXAI name and a new logo that placed the xAI letters inside the SpaceX identity.
Musk gave no timeline. He did not say whether SpaceXSI would be a legal name change or a branding update, whether the @SpaceXAI handle on X would change, or how the shift would apply to products like Grok. The company had not issued a formal announcement as of Sunday morning.
The change would reach well beyond a chatbot. SpaceXAI now houses Grok, the X platform, the Colossus training clusters in Memphis and the coding tool Cursor, which SpaceX acquired in August. It also runs the orbital compute effort SpaceX is building around Nvidia hardware, which Musk said during the company’s first earnings call would be exclusive to Nvidia.
It’s unclear if rivals like Anthropic, OpenAI, Google, Meta and Nvidia have plans to also rename their companies or products. OpenAI CEO Sam Altman has continued to say “AI” in public, while Nvidia CEO Jensen Huang has gone partway, describing data centers as “super intelligence factories.”
The rename would also line up SpaceX’s AI branding with the federal government’s language as Musk takes on a new advisory role at the Pentagon, where he is helping lead the Project Meridian study on the future of warfare.
Starlink is launching a new beta path for ordinary property owners and local operators to turn a single Starlink kit into a small shared-access business for passive income.
Under the Starlink for Communities program, a host installs one dish and router setup in a location with nearby demand: an apartment complex, campground, rural crossroads, or event site. Neighbors or local users can buy short-term passes rather than full individual subscriptions, giving the Starlink provider a potential path to passive income.
Hour, day, and week passes cover one device. A month pass covers up to four. Starlink handles account creation, payments, access controls, and the satellite link itself. The host’s role is mainly placement, power, and basic upkeep, with earnings tied to each paid connection.
Big news! SpaceX is introducing a new @Starlink for Communities program that lets you earn money by providing Starlink internet to your neighbors or people nearby, who can pay for access by the hour, day, week, or month.

The model echoes the passive-income vision long attached to Tesla’s Robotaxi plans, and it seems like it’s something Musk has hinted toward in the past as he believes AI will make the need to work relatively optional. In both cases, the platform owns the hard parts of matching, billing, and network management, while an individual supplies a physical asset that sits idle much of the time.
A Starlink host’s dish can serve multiple nearby users without each household buying and installing its own terminal. A Tesla owner, under the stated Robotaxi concept, would leave a vehicle enrolled in the fleet during unused hours so the car generates rides while the owner is at work or asleep.
Both arrangements convert under-utilized hardware into a revenue stream. They also let the company scale coverage or capacity without owning every endpoint.
Differences are practical. A Starlink kit is a fixed, relatively low-cost terminal whose main constraint is local congestion and line-of-sight. A Tesla Robotaxi is a mobile, high-value vehicle whose earnings depend on demand density, utilization rates, insurance, cleaning, and charging.
Starlink’s program is already accepting host applications in multiple countries and describes the revenue split as ongoing. Tesla’s owner-network version remains more aspirational.
The company currently operates a limited company-controlled robotaxi service in select areas and has solicited interest from fleet buyers for Cybercab vehicles, while private Full Self-Driving owners have not yet been able to dispatch their own cars for paid rides at scale.
Tesla primes Cybercabs for 4K streaming and high bandwidth gaming with Starlink integration
Starlink is a satellite broadband service operated by SpaceX that uses a constellation of low-Earth-orbit satellites to deliver internet to locations where terrestrial broadband is slow, expensive, or absent. It has grown to millions of subscribers worldwide by selling direct residential, mobile, and enterprise terminals, and have become widely available at a wide array at retail locations like Target and Best Buy.
The Communities program extends that reach by letting hosts resell short bursts of capacity to people nearby, while also providing high-speed internet access to those who are simply around a Starlink user.

SpaceX’s midnight spy satellite launch quietly set a new record
Falcon Heavy launched its first NRO mission while SpaceX landed four boosters in one day.
SpaceX closed out one of its busiest days ever with a midnight Falcon Heavy launch from Florida, and the rocket’s two side boosters came home to finish off a landing record the company had never set before.
Falcon Heavy lifted off from Launch Complex 39A at NASA’s Kennedy Space Center at 11:54 p.m. ET Thursday carrying NROL-97, a classified payload for the National Reconnaissance Office. It was the first time the NRO has flown on Falcon Heavy after 22 missions on Falcon 9, and the first NRO mission bought through the National Security Space Launch Phase 3 Lane 2 contract awarded in 2025, according to Spaceflight Now.

Roughly eight minutes after liftoff, side boosters B1104 and B1072 touched down at Landing Zones 1 and 2 at Cape Canaveral Space Force Station, setting off double sonic booms across Brevard County. B1104 was flying for the second time and B1072 for the fourth. Both last flew on August 30 on NASA’s Nancy Grace Roman Space Telescope, making NROL-97 the quickest turnaround between Falcon Heavy missions to date. The brand new center core, B1106, was expended in the Atlantic so the payload could reach its high energy orbit, and SpaceX’s mission page noted the fairing had previously flown on the NROL-95 mission in July.
The two landings capped a record for SpaceX. Earlier Thursday, Falcon 9 booster B1101 returned to Landing Zone 40 after sending the Crew-13 astronauts to the International Space Station, and another Falcon 9 launched the Transporter-18 rideshare with 130 payloads from Vandenberg Space Force Base in California. Spaceflight Now reported it was the first time SpaceX has landed four boosters in a single day, wrapping up the triple header Teslarati previewed on Wednesday.

The mission also brought Landing Zone 1 back for what may be its final landing. SpaceX first landed an orbital class booster there in December 2015, but its lease on the former Launch Complex 13 site ended in 2025 as the company moved Florida landings to new pads at its own launch complexes. With LZ-40 already holding the Crew-13 booster, SpaceX brought LZ-1 back into service for one more night. Launch tracker Next Spaceflight listed NROL-97 as the final expected landing at the site.
NROL-97 adds to a fast growing stack of national security work for SpaceX. The company has flown four Space Force missions from Vandenberg since mid August, several believed to carry Starshield satellites, pushing its Pentagon contract total for 2026 past $8 billion. Elon Musk was also named this week to help lead the Pentagon’s Project Meridian study on the future of warfare.
The Florida doubleheader stood out for another reason. The Space Coast saw only one launch in all of September as SpaceX shifts more of its East Coast infrastructure toward Starship, which reached orbit for the first time on Flight 14 just three days earlier.
