NASA’s next Mars rover will pave the way for humans
NASA’s Mars 2020 rover is scheduled to land on the red planet in February 2021, and when it does, it will touch down in Jezero Crater, the site of an ancient lake that existed 3.5 billion years ago. The next generation rover, which will get an official name soon, will build on the success of the robotic explorers who came before it by collecting the first samples of Mars for a future return to Earth.
But the new rover will also lay the groundwork for future human exploration by testing new technologies.
The Mars 2020 rover, which looks nearly identical to the Curiosity rover that landed in 2012, will begin its mission exploring Jezero Crater. The six-wheeled rover is equipped with a suite of instruments designed to help it look for signs of life called biosignatures.

NASA believes that Mars was habitable sometime in its past. The inhospitable desert-like planet we see today was not always the case. Mars’ once ample atmosphere eroded over time, stripped away by solar particles, resulting in the thin atmosphere we see today.
But so far, we haven’t been able to detect any real signs of ancient life yet. The rover’s team thinks that its specialized suite of instruments will change that.
The twin Mars Exploration Rovers (Spirit and Opportunity) were tasked with finding evidence of water, and they were successful right out of the gate. The Mars Science Laboratory (aka Curiosity) was designed to understand habitability and if the conditions were right for life. Now, the Mars 2020 rover will take that one step further and search for actual signs of life.

The 2020 rover will do so by drilling into its surroundings and extracting samples that will be returned to Earth at a later time. Returning the samples is a challenge that NASA is already starting to tackle. The agency estimates that the earliest it can send a mission to fetch the rover’s samples would be some time around 2026 or 2027.
In the meantime, 2020 will be busy sciencing the heck out of Mars to search for microbial life as well as testing out technologies that future human missions will rely on.
Here’s how four of those instruments will work.
Terrain Relative Navigation
Landing on Mars is tricky. To date, only about half of the missions attempted have successfully touched down on the red planet. The 2020 rover will be equipped with a specialized feature to help it avoid any potential hazards in the landing zone.
Past missions, like Curiosity, needed a landing spot that was free of debris (like rocks, boulders, etc). But 2020 will be able to navigate around them. That’s because the rover is equipped with a unique lander vision system. This system take pictures during the parachute descent stage. It then compares those images to an onboard map.

The computer matches the map (which is created from orbital imagery), to create a guide that can identify landmarks such as craters and mountains.
The system then ranks landing sites based on safety, and can even identify a hazard. The Mars 2020 mission will be the first to test out this new system. If all goes well, it will be used on future missions, including human missions to Mars and even the moon.
MOXIE
Astronauts traveling to Mars will need oxygen to breathe and to use as rocket fuel. However, hauling it with the other cargo is expensive and not a viable solution. The Mars 2020 rover is equipped with an instrument on called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE for short).
MOXIE will convert carbon dioxide (a gas that’s abundant on Mars) into the oxygen, which astronauts can use as needed. 2020 is equipped with a small, prototype version of the equipment needed for future human missions.
The team will study how the experiment performs and use that data to scale up the technology to use on subsequent missions. But how will it work?
MOXIE can only run for a few hours at a time, and only about once a month. (That’s because the system uses a full day’s worth of rover power each time it runs.) Humans use about 20 grams per hour of oxygen and MOXIE can only produce about half of that.
In order to support a crew of 4-6 astronauts and be able to generate propellant, future iterations of MOXIE will need to produce about 200 times that amount of oxygen.
MEDA
The Mars Environmental Dynamics Analyzer, aka MEDA, is a suite of sensors designed to study the Martian weather, as well as dust and radiation and how they change over the Martian seasons.

Day and nighttime temperatures on Mars can fluctuate by as much as 80 or 90 degrees. MEDA will help scientists track those changes as well as measure radiation from the surface, to understand how much the sun heats the air. This solar heating causes changes in the Martian wind and can help scientists better understand the Martian water cycle.
Understanding the current weather patterns and environment could also lead to a better understanding of Mars’s history and shed light on how it transitioned from a warm, habitable planet into the dusty, cold desert we see today.
RIMFAX
The Mars 2020 rover will be equipped with a ground-penetrating radar instrument: Radar Imager for Mars’ Subsurface Experiment, or RIMFAX.

Scientists hope that RIMAX will help them study the history of Jezero Crater by peering below the surface. With the instrument’s help, scientists will be able to look at subsurface rock and ice. To date, only orbital observations have been made of the Martian polar ice, but this will increase our understanding of the planet’s inner geology.
The Mars 2020 rover is scheduled to launch in July of 2020, and will land on the Martian surface six months later. If all goes according to plan, we may finally be able to answer the question of whether or not Mars once hosted life.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket
Space Force drops ULA for SpaceX on GPS launch after Vulcan rocket anomaly investigation halts flights.
The U.S. Space Force announced today it is switching an upcoming GPS III satellite launch from United Launch Alliance’s Vulcan rocket to a SpaceX Falcon 9, a move that is as much a reflection of Vulcan’s mounting problems as it is a validation of SpaceX’s growing dominance in national security space launch. The GPS III Space Vehicle 09, originally contracted to fly on Vulcan this month, will now target a late April liftoff on Falcon 9, marking the fourth consecutive GPS III satellite the Space Force has moved to SpaceX after contracts were originally awarded to ULA.
The immediate trigger is a solid rocket motor anomaly that occurred on February 12 during Vulcan’s USSF-87 mission. Although the payloads reached orbit and ULA declared the mission successful, the company characterized the malfunction as a “significant performance anomaly” and has since paused all military launches on Vulcan pending a root cause investigation.
“With this change, we are answering the call for rapid delivery of advanced GPS capability while the Vulcan anomaly investigation continues,” said Systems Delta 81 Commander Col. Ryan Hiserote. “We are once again demonstrating our team’s flexibility and are fully committed to leverage all options available for responsive and reliable launch for the Nation.”
The broader reality is that SpaceX’s reliability record and launch cadence have made it the path of least resistance for the Pentagon, and bodes well with Elon Musk’s plans to IPO SpaceX sometime this year. Its Falcon 9 is the most flight-proven rocket in history, and the Space Force’s Rapid Response Trailblazer program was specifically designed to enable exactly this kind of provider swap for GPS missions, and effectively building SpaceX’s flexibility into the national security launch architecture by design.
For ULA, the stakes are existential. The company entered 2026 with aspirations of finally turning a corner after years of Vulcan delays, with interim CEO John Elbon pointing to a backlog of over 80 missions as reason for optimism. Meanwhile, SpaceX’s contracts with the Space Force have given it a formal pathway to take on even more national security launches going forward.
The significance of today’s announcement extends beyond one satellite swap. It reinforces that America’s most critical space infrastructure, including GPS, missile warning, and beyond, is increasingly dependent on a single commercial provider.

SpaceX’s Starship V3 is almost ready and it will change space travel forever
SpaceX is targeting April for the debut test launch of Starship V3 “Version 3”
SpaceX is closing in on one of the most anticipated rocket launches in history, as the company readies for a planned April test launch and debut of its next-gen Starship V3 “Version 3”.
The latest iteration of Starship V3 has a slightly taller Super Heavy booster and Starship upper stage than their predecessors, and produce stronger, more efficient thrust using SpaceX’s upgraded Raptor 3 engines. V3 also features increased propellant capacity, targeting a total payload capacity of 200 tons to low Earth orbit with full reusability, compared to around 35 tons for its predecessor. With Musk’s lifelong aspiration to colonize Mars one day, the increased payload capacity matters enormously, because Mars missions require moving massive amounts of cargo, fuel, and eventually, people. But the most critical upgrade may be orbital refueling. SpaceX’s entire deep space architecture depends on moving large amounts of propellant in space, and having orbital refueling capabilities turn Starship from just a rocket into a true transport system. Without it, neither the Moon nor Mars is reachable at scale.

A fully reusable Starship and Super Heavy, SpaceX aims to drive marginal launch costs down and at a tenfold reduction compared to current market leaders. To put that in perspective, getting a kilogram of cargo to orbit today costs thousands of dollars. Bring that number down far enough and space stops being an exclusive domain. That price point unlocks mass deployment of satellite constellations, large-scale science payloads, and affordable human transport beyond Earth orbit. It also means the Moon stops being a destination we visit and starts being one we inhabit.
NASA expects Starship to take off for the Moon’s South Pole in 2028, with the ultimate goal of establishing a permanently crewed science station there. A successful V3 flight this spring keeps that timeline alive. As for Mars, Musk has shifted focus toward building a self-sustaining city on the Moon first, arguing that the Moon can be reached approximately every 10 days versus Mars’s 26-month alignment window. Mars remains the horizon, but the Moon is the proving ground.
Elon Musk hasn’t been shy with hyping the upcoming Starship V3 launch. In a social media post on Wednesday, he confirmed the first V3 flight is getting closer to launch. SpaceX also announced its initial activation campaign for V3 and Starbase Pad 2 was complete, wrapping up several days of cryogenic fuel testing on a V3 vehicle for the first time. The countdown is on. April can’t come soon enough.

Starbase after dark: Musk’s latest photo captures a Spaceport on the brink of history
SpaceX’s Starbase city in Boca Chica, Texas is rapidly transforming the southern tip of the Lone Star State into one of the most ambitious launch complexes in history.
A striking nighttime photograph of SpaceX’s Starbase facility in Boca Chica, Texas, shared recently by Elon Musk on X, offers a dramatic glimpse of an operation that is rapidly transforming the southern tip of the Lone Star State into one of the most ambitious launch complexes in history.
The most immediately visible change in the photo is the presence of two fully erected Starship launch towers dominating the coastal skyline. The second orbital launch pad, known as Pad B, now features its fully erected tower, OLIT-3, which stands approximately 474 feet tall and incorporates an integrated water-cooled flame trench designed to minimize damage and reduce turnaround time between launches. The dual-tower silhouette against the night sky signals a decisive shift from experimental testing facility to high-cadence launch operations.

Back at Starbase, Pad 2 is approaching hardware completion, with upgraded chopstick arms, a new chilldown vent system, and all 20 hold-down arms now fitted with protective doors to shield them from the intense exhaust of up to 33 Raptor 3 engines, according to a deeper dive by NASASpaceFlight.
SpaceX has also received approval to nearly double the footprint of the Starbase launch site, with groundwork already underway to add LNG liquefaction plants, expanded propellant storage, and additional ground support infrastructure.
The photo also carries a milestone civic dimension. Starbase officially became a Texas city in May 2025 after a community vote, with SpaceX employees elected as mayor and commissioners of the newly incorporated municipality. That legal status streamlines launch approvals and gives SpaceX direct control over local infrastructure decisions.
The FAA has approved an increase in launches from Starbase in Texas from five to twenty-five per year, clearing the runway for the kind of flight frequency needed to fulfill Starship’s ultimate mission of ferrying cargo and crew to the Moon, servicing the Department of Defense, deploying next-generation Starlink satellites, and eventually establishing Elon Musk’s long sought after goal of a self-sustaining human presence on Mars.
Seen from above in the dark, Starbase looks less like a test site and more like a spaceport.
