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.

Elon Musk reveals when SpaceX will perform first-ever Starship catch
“Starship catch is probably flight 13 to 15, depending on how well V3 flights go,” Musk said.

Elon Musk revealed when SpaceX would perform the first-ever catch attempt of Starship, its massive rocket that will one day take life to other planets.
On Tuesday, Starship aced its tenth test flight as SpaceX was able to complete each of its mission objectives, including a splashdown of the Super Heavy Booster in the Gulf, the deployment of eight Starlink simulators, and another splashdown of the ship in the Indian Ocean.
It was the first launch that featured a payload deployment:
SpaceX Starship Flight 10 was so successful, it’s breaking the anti-Musk narrative
SpaceX was transparent that it would not attempt to catch the Super Heavy Booster, something it has done on three previous occasions: Flight 5 on October 13, 2024, Flight 7 on January 16, and Flight 8 on March 6.
This time, it was not attempting to do so. However, there are bigger plans for the future, and Musk detailed them in a recent post on X, where he discussed SpaceX’s plans to catch Starship, which would be a monumental accomplishment.
Musk said the most likely opportunities for SpaceX to catch Starship itself would be Flight 13, Flight 14, and Flight 15, but it depends on “how well the V3 flights go.”
The Starship launched with Flight 10 was a V2, which is the same size as the subsequent V3 rocket but has a smaller payload-to-orbit rating and is less powerful in terms of initial thrust and booster thrust. Musk said there is only one more V2 rocket left to launch.

V3 will be the version flown through 2026, as V4, which will be the most capable Starship build SpaceX manufactures, is likely to be the first company ship to carry humans to space.
Musk said that SpaceX planned to “hopefully” attempt a catch of Starship in 2025. However, it appears that this will likely be pushed back to 2026 due to timing.
SpaceX will take Starship catch one step further very soon, Elon Musk confirms
SpaceX would need to launch the 11th and 12th test flights by the end of the year in order to get to Musk’s expected first catch attempt of Flight 13. It’s not unheard of, but the company will need to accelerate its launch rate as it has only had three test flights this year.

SpaceX aces Starship test flight 10 with successful payload deployment
The mission began at 6:30 p.m. local time in Starbase, Texas, when the launch of Starship initiated. After about eight minutes, stage separation was completed, and the Super Heavy Booster headed back down to Earth for a planned splashdown in the Indian Ocean:

SpaceX aced its tenth Starship test flight on Tuesday night after multiple delays pushed the mission back to this evening. Originally scheduled for Sunday night, SpaceX had two delays push the flight back to Tuesday, which ultimately provided ideal conditions for a launch attempt.
The tenth test flight of Starship had several objectives, including a successful splashdown of the booster in the Gulf of America, the deployment of eight Starlink simulation modules from the PEZ dispenser, and a splashdown of the ship in the Indian Ocean.
SpaceX successfully achieved all three of these objectives, making it one of the most successful test flights in the Starship program. There was no attempt to catch the booster this evening, as the company had been transparent about it ahead of the launch.

Starship was then the main focus of the rest of the broadcast as it completed its ascent burn and coasted through space, providing viewers with spectacular views as the mission headed toward new territory, including the deployment of Starlink simulators. This would be the first time SpaceX would attempt a payload deployment.
The deployment works like a PEZ dispenser, as the simulators were stacked on top of one another and would exit through a small slit one at a time.
This occurred roughly 20 minutes into the mission:

An hour and six minutes into the flight, Starship reached its final destination, which was the Indian Ocean. A successful splashdown would bring closure to Starship’s tenth test flight, marking the fifth time a test flight in the program’s history did not end with vehicle loss.
It was also the first of four test flights this year that will end with Starship being recovered.

WATCH: SpaceX attempts Starship’s tenth test flight after two delays
This evening, SpaceX has already stated that conditions appear to be approximately 45 percent favorable for launch. This is ten percent less than last night, when the mission was eventually scrapped around 7 p.m. local time.

SpaceX is set to launch Starship tonight, provided the weather cooperates and everything with the ship goes smoothly.
This is SpaceX’s third attempt to launch Starship for its tenth test flight, with Sunday’s and Monday’s attempts both being scrapped due to a leak and unfavorable weather conditions on the respective days.
