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.

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Musk says SpaceX is aiming for a timeline of roughly three weeks from now, which would come about ten weeks after the previous launch.

Coincidentally, it would bring the two launches 69 days apart, and if you know anything about Elon Musk, that would be an ideal timeline between two launches.

🚨 Just wanted you to know, Starship 10’s projected test flight date, according to Grok, is August 4.
Starship’s ninth test flight took place on May 27.
August 4 is 69 days after May 27.

SpaceX is coming off a test flight in which it lost both the Super Heavy Booster and the Upper Stage in the previous launch. The Super Heavy Booster was lost six minutes and sixteen seconds into the flight, while SpaceX lost communication with the Ship at 46 minutes and 48 seconds.

Musk is aiming for the tenth test flight to take place in early August, he revealed on X:

Launching again in ~3 weeks
— Elon Musk (@elonmusk) July 14, 2025

This will be SpaceX’s fourth test flight of the Starship program in 2025, with each of the previous three flights bringing varying results.

IFT-7 in January brought SpaceX its second successful catch of the Super Heavy Booster in the chopstick arms of the launch tower. The ship was lost after exploding during its ascent over the Turks and Caicos Islands.

IFT-8 was on March 6, and SpaceX caught the booster once again, but the Upper Stage was once again lost.

The most recent flight, IFT-9, took place on May 27 and featured the first reused Super Heavy Booster. However, both the Booster and Upper Stage were lost.

The Federal Aviation Administration (FAA) hit SpaceX with a mishap investigation for Flight 9 on May 30.

SpaceX is preparing for a new launch date for the Ax-4 mission to the International Space Station (ISS).

SpaceX, Axiom Space, and NASA addressed recent technical challenges and announced a new launch date of no earlier than Thursday, June 19, for the Ax-4 mission. The delay from June 12 allowed teams to assess repairs to small leaks in the ISS’s Zvezda service module.

NASA and Roscosmos have been monitoring leaks in the Zvezda module’s aft (back) segment for years. However, stable pressure could also result from air flowing across the hatch seal from the central station. As NASA and its partners adapt launch schedules to ensure station safety, adjustments are routine.

“Following the most recent repair, pressure in the transfer tunnel has been stable,” a source noted, suggesting the leaks may be sealed.

“By changing pressure in the transfer tunnel and monitoring over time, teams are evaluating the condition of the transfer tunnel and the hatch seal between the space station and the back of Zvezda,” the source added.

SpaceX has also resolved a liquid oxygen leak found during post-static fire inspections of the Falcon 9 rocket, completing a wet dress rehearsal to confirm readiness. The Ax-4 mission is Axiom Space’s fourth private astronaut trip to the ISS. It will launch from NASA’s Kennedy Space Center in Florida on a Falcon 9 rocket with a new Crew Dragon capsule.

“This is the first flight for this Dragon capsule, and it’s carrying an international crew—a perfect debut. We’ve upgraded storage, propulsion components, and the seat lash design for improved reliability and reuse,” said William Gerstenmaier, SpaceX’s vice president of build and flight reliability.

The Ax-4 mission crew is led by Peggy Whitson, Axiom Space’s director of human spaceflight and former NASA astronaut. The Ax-4 crew includes ISRO astronaut Shubhanshu Shukla as pilot, alongside mission specialists Sławosz Uznański-Wiśniewski from Poland and Tibor Kapu from Hungary. The international team underscores Axiom’s commitment to global collaboration.

The Ax-4 mission will advance scientific research during its ISS stay, supporting Axiom’s goal of building a commercial space station. As teams finalize preparations, the mission’s updated launch date and technical resolutions position it to strengthen private space exploration’s role in advancing space-based innovation.
