Watch NASA’s Mars 2020 Rover go for a test drive in preparation for landing on Martian soil
NASA engineers witnessed their newest Mars rover take its first steps in preparation for its next mission that will search for fossilized remains of ancient life on the red planet.
The test took place inside the Spacecraft Assembly Facility clean room at NASA’s Jet Propulsion Laboratory in Pasadena, California. Engineers clad in white bunny suits—special cleanroom attire worn in order to keep the rover’s delicate instruments very, very clean—watched the yet-to-be-named rover inch forward as part of the crucial pre-flight test, which lasted just over 10-hours.
“Mars 2020 has earned its driver’s license,” Rich Rieber, the lead mobility systems engineer for Mars 2020, said in a news release. “The test unambiguously proved that the rover can operate under its own weight and demonstrated many of the autonomous-navigation functions for the first time. This is a major milestone for Mars 2020.”
During the test, NASA engineers noticed no problems, as the six-wheeled rover successfully performed all its required tasks: it rolled forward and backward and even pirouetted. According to NASA, the rover’s systems, all working in concert, enabled it to steer, turn and drive with ease.
The testing of the vehicle’s autonomous navigation system went well. Since these systems performed perfectly under Earth’s gravity, engineers expect them to perform just as well under Mars’ gravity, which is only 38% of what we experience on Earth.
The test went so well that NASA says the “next time the Mars 2020 rover drives, it will be rolling over Martian soil.” The Mars 2020 rover is scheduled to launch in July 2020, followed by a landing in Jezero Crater on February 18, 2021.
“A rover needs to rove, and Mars 2020 did that,” John McNamee, project manager for Mars 2020, said in a statement. “We can’t wait to put some red Martian dirt under its wheels.”
During its initial test drive, the rover crept forward in small, 3-feet ( 1-meter) increments, enabling the engineers to properly assess its movement and steering abilities. The rover also drove over small ramps designed to simulate uneven Martian terrain.
Engineers were also able to collect data from the vehicle’s Radar Imager for Mars’ Subsurface Experiment (RIMFAX)—an instrument that uses radar waves to scan the ground below the rover. Depending on the terrain, once on Mars, RIMFAX will penetrate the ground, probing the red planet’s subsurface to depths of more than 30-feet (or 10-meters).

Curiosity, the Mars 2020 rover’s predecessor currently roaming around on Mars, is predominantly commanded by people back on Earth. However, the rover does have the ability to autonomously choose where to fire its laser spectrometer. As part of its onboard science arsenal, the instrument—called ChemCam—is designed to analyze the chemical composition of nearby rocks and soil.
Mars 2020, on the other hand, will be more independent than any of its predecessors. Equipped with advanced auto-navigation software, the rover will drive with the help of a dedicated onboard computer operating on data collected from the vehicle’s high-resolution, wide-field color cameras.
NASA engineers estimate that the rover will travel an average of 650 feet (200 meters) per day. For comparison, Curiosity’s current distance record for a single day is 702 feet (214 meters), although that’s not typical. The Mars 2020 rover will also be sporting more durable wheels. Curiosity’s wheels are visibly worn after seven years on the Martian surface; engineers hope Mars 2020’s wheels will hold up better.

Once on Mars, the rover will land at Jezero Crater—a former lake bed, rich in mineral deposits known for preserving microfossils here on Earth. In this crater, the rover will search for any signs that life may have once existed on Mars.
While acting as a remote scientist, the rover will unlock clues about the planet’s climate and geology as well as collect samples that will be returned to Earth sometime in the future.
Following the loss of the Opportunity rover, Curiosity has been the sole robot roaming the Martian surface. That will change in 2021, but they won’t be the only ones.
They will be joined by another: The European Space Agency is teaming up with Russia to send their version of the Mars 2020 rover. The Rosalind Franklin ExoMars rover will arrive on Mars at a soon-to-be-announced location, in 2021.

SpaceX tells the FCC that Starship Flight 14 is going to orbit
SpaceX filed with the FCC for Starship Flight 14, its first true orbital launch attempt.
SpaceX has asked the Federal Communications Commission for permission to fly Starlink terminals during Starship’s fourteenth flight test, and the filing lays out a genuine trip to orbit, something the program has never attempted.
Every Starship flight so far, including Flight 13’s successful splashdown in the Indian Ocean on July 24, has flown a suborbital arc that ends with the ship reentering the atmosphere within the same hour it launches. The FCC paperwork describes a mission profile built around an actual orbital insertion instead.
The payload is the other half of the story. Flight 13 carried 20 production Starlink V3 satellites, but because that mission never reached orbit, the satellites reentered along with the ship rather than joining the constellation, something Teslarati covered in detail after SpaceX released footage shot from one of those satellites as it drifted away from Starship in space. Flight 14 is designed to close that gap. If the orbital insertion holds, the roughly 20 V3 satellites onboard would separate into an operational orbit and could eventually go into service, each one rated for about 1 terabit per second of downlink capacity by SpaceX’s own account.
SpaceX announces new Starbase for ‘thousands of Starship launches annually’
Elon Musk first flagged the orbital attempt during SpaceX’s August 4 earnings call, the company’s first as a public entity following its June IPO under the ticker SPCX. He also floated catching the ship with the Starbase tower on the same flight, an idea he walked back on August 20, saying the catch attempt would more likely come “in a few months,” as Teslarati reported at the time. Flight 14 will instead target a splashdown for the ship in the Indian Ocean, the same recovery method used since Flight 12.
Hardware has been catching up to the ambition. Booster 21 completed a full 33-engine static fire on August 28, and Ship 41 finished its own six-engine test the week before. An airspace briefing circulated to pilots on August 20 listed September 15 as the target date, later than the end of August window Musk mentioned on the earnings call, though SpaceX has not confirmed a launch date publicly and Starship schedules routinely slip while hardware and FAA paperwork line up.
The FCC filing itself does not guarantee a launch date. It covers communications authority, and not flight readiness, considering SpaceX still needs Ship 41 fully stacked and cleared by the FAA before Flight 14 can fly. But the filing is a real marker of intent and it puts a specific regulatory process behind what had so far only been Musk’s word on the earnings call.

SpaceX would not exist if this crucial early launch failed, Musk says
Elon Musk recently restated a fact that still defines SpaceX’s origin story: if Falcon 1’s fourth launch had failed, the company would not exist. The comment answered a reminder that after three consecutive losses, SpaceX had money for only one more attempt.
On X, Peter Diamandis said that the present-day acknowledgement of SpaceX’s success does not discount the rough start the company had. “Almost nobody remembers that Elon’s first rocket failed three times, and there was money for exactly only one more attempt.”
Musk said, “If the 4th launch had failed, SpaceX would not exist.”

In late 2008, the firm was nearly out of cash. Another failure would have ended payroll, closed the Hawthorne factory, and left the Falcon 9 and Dragon programs as unfinished drawings.
The first flight lifted off from Omelek Island on 24 March 2006. Thirty-three seconds later, a corroded aluminum fitting on a fuel line leaked. Kerosene ignited around the Merlin engine, control was lost, and the vehicle came apart. The small DARPA payload, FalconSAT-2, survived the short flight only to land on a storage shed near the pad. Investigators later traced the fitting to a materials mix-up that should never have reached the rocket.
Flight 2, on 21 March 2007, looked far better at first. The first stage burned cleanly and handed off to the Kestrel-powered upper stage. The vehicle crossed 100 kilometers and reached a peak of about 289 kilometers. Then propellant slosh in the second-stage tank started a circular coning motion that grew until the engine shut down. Telemetry faded as the stage tumbled, and SpaceX had reached space but not orbit. Over the next year, the team redesigned everything from the ground up, including tanks, baffles, and the new regeneratively cooled Merlin 1C.
That engine flew on Flight 3 on 2 August 2008. The first stage performed almost perfectly and reached 217 kilometers. After main-engine cutoff, leftover fuel in the cooling channels produced a faint residual thrust, roughly 10 pounds per square inch of chamber pressure. On a Texas test stand, the effect was invisible beneath ambient air pressure. In vacuum it was enough to push the spent first stage back into the second stage after separation. The stages collided, the upper stage spun, and the mission was lost. Musk later said a slightly longer delay before staging would have saved the flight.
Six weeks later, the team assembled Flight 4 from remaining parts and flew it on 28 September 2008 at 23:15 UTC. The payload was Ratsat, a 165-kilogram aluminum mass simulator built in-house. Staging was delayed so residual thrust could decay. The Kestrel ignited, the fairing split away, and nine and a half minutes after liftoff the vehicle was in orbit. After a coast, the second stage restarted, settling into a 621-by-643-kilometer path at 9.35 degrees inclination. Falcon 1 became the first privately developed liquid-fueled rocket to reach Earth orbit. Musk called the insertion “middle of the bull’s-eye.”
SpaceX restores a Falcon 1 rocket for 10th anniversary of first launch success
That success unlocked NASA’s Commercial Resupply Services award later that year. Without it, there would have been no Falcon 9, no reusable first stages, and no Dragon cargo or crew flights to the International Space Station. Launch prices would have remained far higher. Starlink’s constellation would not exist; broadband from low Earth orbit would still be a paper concept.
Ride-share markets, high launch cadence, and the current pace of lunar and Mars hardware would be years behind. Communications, Earth observation, and the cost of putting anything into space would look more like the 2000s than the 2020s.
One extra second of residual thrust in August 2008 would have written a different decade.

Elon Musk gives a timeline for SpaceX’s first Starship catch attempt
SpaceX CEO Elon Musk announced today that the company will likely attempt to catch the Starship upper stage with its launch tower arms “in a few months.”
In a post on X, Musk wrote, “Looks like we will probably catch the ship with the tower in a few months. If there had been a tower out to sea where we practiced landing the ship, it would have been caught.” He added that the first reflight of a Starship vehicle is expected by the end of 2026 or early 2027, describing it as “a fork in the road of history for consciousness reaching the stars.”

Musk’s prediction comes amid ongoing progress toward full reusability of the Starship system, a two-stage rocket designed for rapid turnaround and dramatically lower launch costs. Catching the upper stage, known simply as “ship,” with the Mechazilla tower’s mechanical arms would mark a major milestone. It would allow both stages to return directly to the launch site for quick refurbishment and reuse, eliminating the need for ocean recovery.
Musk has previously signaled plans for a ship catch. In July, shortly after SpaceX’s wildly successful Starship 13 mission, he stated that the company would attempt to catch the ship with the tower on the next flight unless problems emerged in the mission data review. Earlier comments also outline conditions such as successful soft ocean landings before attempting a land recovery to minimize risk.
SpaceX has solved Starship’s biggest challenge, Elon Musk says
The latest update from Musk adjusts this timeline to a few months, reflecting the iterative nature of the test campaign.
SpaceX has already demonstrated the tower catch technique successfully with the Super Heavy booster on a couple of occasions. The first successful booster catch occurred during Flight 5 in October 2024, when the massive first stage returned to the Starbase pad in Texas and was plucked from the air by the tower arms.
Additional catches followed on later flights, including Flight 7, proving the concept for the booster and building confidence in the system as a whole.
Achieving a similar catch for the upper stage would represent a significant step forward. The ship returns from much higher speeds and greater heat loads after orbital or near-orbital flight. Success would advance SpaceX’s goal of full and rapid reusability, potentially reducing the cost of access to orbit by a factor of 100 or more and supporting ambitions for frequent satellite deployments, lunar missions, and eventual Mars flights.
Musk has long emphasized that true reusability, refueling rather than discarding hardware, is essential for making humanity a multi-planetary species.
As SpaceX continues refining Starship through successive test flights, the coming months will test whether the ambitious catch timeline can be met. The combination of prior booster successes and improving ship landing precision suggests the company is steadily closing in on this historic capability.
