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 is opening up its internet service, Starlink, to those impacted by Hurricane Melissa, as it made landfall in Jamaica and the Bahamas as a Category 5 storm.

Hurricane Melissa is expected to reach wind speeds of over 165 MPH over the next few days as it extends out into the Atlantic Ocean by Thursday and Friday.

Citizens in Jamaica and the Bahamas have been preparing for the storm for the past week, getting necessary goods together and preparing for the massive storm to arrive. It finally did yesterday, and the first images and video of the storm are showing that it could destroy many parts of both countries.

Starlink is now being opened up for free until the end of November for those impacted by the storm in Jamaica and the Bahamas, SpaceX announced today:

It is a move similar to the one the company made last year as Hurricane Helene made its way through the United States, destroying homes and property across the East Coast. SpaceX offered free service for those impacted by the destruction caused by the storm.

The free Starlink service was available until the end of 2024.

Elon Musk’s companies have also made similar moves to help out those who are impacted by natural disasters. Tesla has offered Free Supercharging in the past, most notably during the California wildfires.

Tesla and SpaceX’s LA fire relief efforts: Cybertrucks, free Starlink and more

One major advantage of Starlink is that it is available for use in situations like this one, where power might be required to operate things like a modem and router.

Internet access is a crucial part of survival in these situations, especially as it can be the last leg some stand on to get in touch with emergency services or loved ones.

SpaceX has reached an incredible milestone with its Starlink program, officially surpassing 10,000 satellites launched into low Earth orbit since starting the program back in 2019.

Last Sunday, October 19, SpaceX launched its 131st and 132nd Falcon 9 missions of 2025, one from Cape Canaveral, Florida, and the other from Vandenberg, California.

The 10,000th Starlink satellite was aboard the launch from California, which was Starlink 11-19, and held 28 v2 mini optimized satellites.

The achievement was marked by a satellite tracker developed by Jonathan McDowell.

The first Starlink launch was all the way back on May 23, 2019, as SpaceX launched its first 60 satellites from Cape Canaveral using a Falcon 9 rocket.

Of the over 10,000 satellites in orbit, the tracker says 8,608 are operational, as some are intentionally de-orbited after becoming faulty and destroyed in the atmosphere.

SpaceX has truly done some really incredible things during its development of the Starlink program, including launch coverage in a global setting, bringing along millions of active subscribers that use the service for personal and business use, locking up commercial partnerships, and more.

Starlink currently operates in around 150 countries, territories, and markets and is available at least somewhere on all seven continents.

Additionally, Starlink has over 5 million subscribers worldwide, and 2.7 million have joined the program over the past year. It has revolutionized internet access on commercial aircraft as well, as several high-profile airlines like Qatar and United, among many others, have already installed Starlink on some of their planes to deliver more stable connectivity for passengers and crew.

SpaceX has the approval to launch 12,000 Starlink satellites from the FAA, but it plans to bring over 30,000 to its constellation, giving anyone the ability to have access to high-speed internet.

SpaceX aces its eleventh Starship test launch on Monday evening, marking the company’s second consecutive takeoff that crossed off each of the planned mission objectives.

It was also the final launch of the V2 Starship rocket. The twelfth test flight will feature the larger V3 Starship rocket, followed by V4, which will eventually make the first trip to Mars.

The launch was overwhelmingly successful. In its 12th test flight, SpaceX was able to achieve every major mission objective, including the second successful deployment of Starlink satellite simulators and the relight of a Raptor engine while in space. The latter achievement demonstrated “a critical capability for future deorbit burns,” the company said.

The ship officially launched at 6:23 p.m. local time in Starbase, Texas, with all 33 engines igniting and sending the Ship to space.

Stage separation occurred just over eight minutes later, and Super Heavy started its descent back to the Gulf of America, where it successfully splashed down. The first part of the launch was complete.

Starlink simulators were deployed about twenty-one minutes after launch, as the Pez dispenser sent the faux-satellites out to space without any issue:

Perhaps the most anticipated part of the launch was with Starship’s banking maneuver and subsequent splashdown in the Indian Ocean.

Prior to Starship 11’s launch and successful re-entry and splashdown, SpaceX had lost a few vehicles during this portion of the previous flights.

However, the company had made tremendous improvements and has now aced two consecutive launches. On Monday, its approach and splashdown were both overwhelmingly successful:

The re-entry phase of this particular Starship launch aimed to gather data on the performance of the heatshield, SpaceX said. The heatshield was intentionally stressed to its limits to determine how much it could withstand without failing.

SpaceX will now turn its focus to the next vehicles, including V3, which is larger, more capable, and will help the company gather even more information about its launches into space:

CEO Elon Musk has said the third-generation Starship rocket will be built and tested by the end of the year.
