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

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 performed a secret test on a specific portion of Starship with its recent 13th test flight last week, CEO Elon Musk revealed.
Starship’s 13th test flight took place last Friday, and in many aspects, it was one of the most overwhelmingly successful launches in the project’s history.
All of the mission objectives were met without incident, both the Super Heavy Booster and Ship managed to perform safe splashdowns in the Gulf of America and the Indian Ocean, respectively, and the deployment of Starlink satellites came and went without any complications.
— Elon Musk (@elonmusk) July 25, 2026
However, there was more on the agenda for SpaceX with Flight 13. Musk revealed an internal test of the ship’s heat shield tiles, as the space exploration company wanted to push them to the limits after previous issues.
Many noticed that Starship’s initial launch seemed to be more accelerated than normal, and that was not a mistake. Musk revealed that SpaceX decided to give Flight 13 an intentionally aggressive acceleration rate in an effort to test how well the tiles would remain attached to the ship:

This flight intentionally had much higher acceleration to test how well the heat shield tiles would remain attached at high dynamic pressure.
Test was successful.
— Elon Musk (@elonmusk) July 25, 2026
SpaceX had issues with some of the heat shield tiles remaining attached early on in the Starship program. The first six test flights presented some kind of anomaly with them, so the company’s big focus with them was to figure out a way to keep them intact through the duration of the flight.
Things truly improved as Flight 10 showed that ceramic tiles generally stayed attached to the ship far better due to refined attachment, as SpaceX utilized pins instead of adhesives. Flights 10 through 13 truly showed some clear progress with the heat shield tiles, and this latest test seems to be where some real progress was noticed, especially by Musk.
The 13th Starship launch last Friday was the second with Starship V3, SpaceX’s latest and greatest iteration of the spacecraft. Goals and ambitions are getting even grander as the project continues to progress. Musk has already hinted that SpaceX will likely try to catch Starship with Flight 14.

Just hours after Starship Flight 13 achieved a successful soft splashdown of its upper stage in the Indian Ocean on July 24, Elon Musk announced an ambitious next step for the company’s next launch of the rocket.
“Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on [the] next flight,” the SpaceX CEO posted on X on Friday.
That “next flight” is expected to be Flight 14. The plan involves returning the Starship upper stage, commonly called the “ship,” to the Starbase launch tower in Texas and catching it mid-air using the same mechanical “chopsticks” arms that have already proven themselves with the Super Heavy booster.

— Elon Musk (@elonmusk) July 25, 2026
A successful catch would mark the first time an orbital-class upper stage has been recovered this way, advancing SpaceX’s goal of full and rapid reusability for the entire vehicle.
SpaceX has already demonstrated the tower-catch technique multiple times with Super Heavy. The first successful catch came on Flight 5 in October 2024, when Booster 12 was plucked from the sky by the Mechazilla arms. Subsequent flights, including those involving Boosters 14 and 15, repeated the feat. Several of those recovered boosters were later inspected, refurbished, and flown again, proving the system’s viability for quick turnaround.

Traditional reusable rockets, such as SpaceX’s own Falcon 9 or Blue Origin’s New Shepard, land on legs either on land or droneships. Rocket Lab has recovered its small Electron first stages by helicopter, but those are far lighter vehicles.
SpaceX Starship just nailed something it’s never done before
The China Academy of Launch Vehicle Technology (CALT), a subsidiary of the China Aerospace Science and Technology Corp. (CASC), completed a catch of its booster on July 10. They are the only entity besides SpaceX to attempt and complete the feat.
Flight 13 provided encouraging data. The ship executed a controlled reentry, flipped, and soft-landed intact in the ocean after deploying Starlink satellites, offering the first clear post-splashdown views of an undamaged heat shield. The Super Heavy booster, meanwhile, experienced a harder splashdown in the Gulf of America.
Musk has previously stressed that ship catches would only follow multiple successful soft ocean landings to minimize risk of debris over land.
If Flight 14 succeeds, SpaceX would take a major stride toward routine, rapid reuse of both stages—critical for lowering launch costs and supporting ambitious plans for lunar and Mars missions. For now, teams are reviewing the Flight 13 data. Should everything check out, the next Starship flight could deliver one of the most spectacular recoveries in aerospace history.

SpaceX Starship just nailed something it’s never done before
SpaceX’s Starship flew successfully Friday, landing both stages and deploying its first Starlink V3 satellites.
Starship’s thirteenth test flight delivered exactly what SpaceX needed with a clean liftoff, two successful stage recoveries, and the first real payload the vehicle has ever carried to space. Booster 20 and Ship 40 lifted off at 5:51 p.m. CT from Starbase, and by the time the mission wrapped roughly an hour later, both halves of the rocket had done exactly what they were supposed to do.
Booster 20 separated from Ship 40 a few minutes into the flight and stuck a controlled splashdown in the Gulf of Mexico about six minutes after liftoff. That is a meaningful turnaround from Flight 12 in May, when the booster lost several engines during its boostback burn before a hard water landing attempt.

Starship 40’s performance was arguably the bigger win. The vehicle deployed the first 20 operational Starlink V3 satellites Starship has ever carried, then flew a suborbital arc to a landing in the Indian Ocean that SpaceX commentator Dan Huot called the company’s softest splashdown yet. “This is a dream scenario for this team that’s trying to get this heat shield data,” Huot said on the live broadcast, according to Space.com’s live coverage. “I’m a little over the moon right now. Wow. Lucky number 13.”
Unlike the mass simulators SpaceX flew on Flight 12, these were production Starlink V3 satellites, meant to extend solar arrays and antennas and attempt to link with the broader constellation before reentering minutes later. Getting real hardware through a full deploy sequence on only the second flight of the V3 generation keeps Starship on schedule for the payload work NASA is counting on for future Artemis lunar landings.
What an awesome launch, really seems like everything went super well and it was all incredibly smooth.
SpaceX is awesome. Very interested to see how the market will respond on Monday pic.twitter.com/KSHmyBfV55

The flight also arrives at a moment when SpaceX needed a win. SPCX has traded below its $135 IPO price since mid-July, as Teslarati reported when the mission slipped to Friday, and short interest has climbed to roughly a third of the tradable float. A clean flight will not fix a balance sheet, but it does answer the one question SpaceX absolutely needed answered this week: whether the fixes made after the July 16 abort would hold up under real flight conditions. They did, on both stages, on the first try after the redesign.
SpaceX has not set a target date for Flight 14, though the company has said it wants to push toward an orbital attempt on the next mission. After Friday, that goal looks a lot more within reach.
