NASA & SpaceX Unveiled How to Land Starship on Mars and Secretly Practicing…
The process of landing on Mars has always been an incredibly complex and challenging technical feat. Methods such as using giant airbags or sky crane systems—though creative—are not yet the optimal solutions for landing humans on the planet’s surface.
So, NASA has developed a groundbreaking landing system for the Red Planet, incorporating and processing data from SpaceX in a completely different approach from what was traditionally expected. Surprisingly, this solution may not be directly related to Starship. However, these studies will provide crucial information about the technical requirements that Starship will need to meet when it finally reaches Mars.
Let’s find out on today’s episode of Alpha Tech:
NASA & SpaceX Unveiled How to Land Starship on Mars and Secretly Practicing…
Before delving into NASA’s newly unveiled method for landing on Mars, it’s essential to first grasp the challenges of touching down on this distant planet.
Landing on Mars presents a set of challenges that are unlike those faced on Earth or the Moon, primarily due to its thin atmosphere. Mars’ atmosphere is denser than the Moon’s but much thinner than Earth’s, which creates a “Goldilocks” problem for landing.
The thin atmosphere on Mars is too sparse to support Earth-like landing techniques that rely on atmospheric drag, such as parachutes or aerodynamic braking. The Red Planet’s atmosphere is extremely thin, less than 1% as dense as Earth’s. Terminal velocity on Mars reaches an astonishing speed of nearly 1,000 km/h—four times faster than on Earth. This means that atmospheric braking alone is insufficient to slow a spacecraft down.
NASA & SpaceX Unveiled How to Land Starship on Mars and Secretly Practicing…
Leading space agencies around the world, including NASA, the European Space Agency (ESA), and especially Russia, have faced this challenge repeatedly. During their efforts, they experienced numerous failures when attempting to land spacecraft on the Martian surface. Only recently have significant breakthroughs been achieved in addressing these challenges.
A key issue that further complicates landing on Mars is the supersonic transition problem. Retro-propulsion, where engines are fired backward to slow the spacecraft during descent, is a common method for landings on the Moon. However, NASA initially believed that retro-propulsion could only work effectively at subsonic speeds, below the speed of sound. The challenge with Mars is that during descent, the spacecraft is traveling at supersonic speeds when it first enters the atmosphere. NASA was concerned that firing engines at these high speeds could destabilize the spacecraft, as shock fronts would form around the vehicle, potentially causing significant turbulence or overheating. The shock from the engine plume could also damage the spacecraft, making retro-propulsion seem impractical for Mars landings.

In this video, nice pictures of large spacious glass domes, as if greenhouses for vegetation of various plants and as a space for people relaxation, are irrelevant.
Serious threat of solar wind rediation renders going underground the only sensible option.
There are many caves and structures under the Martian surface. It is possible to engineer quite comfortable living space there including gigantic underground chambers with beautiful gardens, parks, lakes and sunlight conveyed from the surface through fiberoptics…
H1B Nazi rockets
I just viewed a funny version of the 3 pigs.
He talked about how in the 16th century people used 15 times more words than we do.
Sooo I know saw this video, and the amount of words used in the narrative is so excessive, just to comment that SpaceX will use landing legs for landing on Mars.
Mark CEN CA if you ask me I say landing on Mars is probably an impossibility but I'm no expert that's for sure😂 as far as this video goes I think the time is right I believe there's good content can I for one think it's great I'm still interested regardless of how I feel about the Mars mission
Too much irrelevant information, get to the point faster, video disliked and reported, do better.
why couldn't they kick out a few, redundant, remote builders to knock down a landing zone for future flights when they do that initial, manned fly-by projected for 2035?…
So is there a reason this video was uploaded again? I watched this exact video a while back. It definitely was released before 5 hours ago. Jist curious as to why?
Not to mention, landing and launching from mars would likely create a crater. On earth, you have specifically have a launch platform? On mars this platform doesn't exist
Anti-Elon bots in the comments on cue.
It dint sound like landing there will ever be prefected so wtf a waste of money and time when the money sholud be used to help others no just a huge waste of lifes
Can the 1st mars migration missions be composed of illegal immigrant crews ?!
You can Test & Practice Martian Reentry techniques around Earth.
Since the Martian atmosphere is equal to 100,000 feet anything you do above 100k is like entering Mars.
Even these recent Starship reentries should reveal what would happening if entering Mars at high speed. Just test engine firing (retro) while above 100k and you'll have your answers. You can take it all the way to a virtual standstill in the sky (at 100k) and just let it fall into the ocean.
For a pre-mission landing pad, I'd use a small supply craft containing only landing pads and robotics to remotely prepare the landing pas.
From then on EVERY landing can be on a pad (as early missions include more pads).
the 21st century will be know as the century where humankind began to live in a fantasy world
Infrastructure needs to happen first. You can't jist go full bore and expect that every hing will work? Smaller shuttles to build and way to extract water from the regalith, habitats and a landing pads for starship
I was right .. NASA is taking over
One supply ship can transport 2 landing pads of heat tiles and Stainless. One pad would be 7 each 8m Hex pads. This will be like landing on a drone ships. More and more of these Hex Tiles can delivered.
OK, how is the rarefied atmosphere on Mars different from upper rarefied atmosphere on Earth? Seems like testing of scenarios could be done.
they absolutely have to figure out a way to avoid this insane 26 month window. they should get that figured out as one of the primary objectives. otherwise. there is no rush in building and testing and perfecting the starship. taking huge risk of having to build a special addition for Mars that very well might be considerably different and have to do it all basically, over again and going through the FDA approval sht all over again.
once that is figured out, they should figure out a way to keep the mars dust from kicking up insanely bad. like sending a payload down that literally is all water that sprinkles and waters the land zone, then another payload that is literlaly only cement, not to create a cement pad this way, but just weigh down the landing zone. the cement dusting will stick to the wet mars soil/dust and make it heavy. potentially heavy enough to keep the dust cloud and what ever to a managable landing cloud.
i donno. just a fast brainstorm lol… them are two serious big issues that should flat out be resolved instead of waiting til the last minute and hoping like hell it will be ok and having a method that allows a starship to be landing every 3 months. not 26 months man. thats just fkn stupid. if you try and counter that with multiple ships arriving in a short period of time all together basically, within the 26 month window, its too possible that landing isn't possible at this or that location at that time and so suddenly, you have multiple ships all in high jeopardy of some kind of crashing happening by the time they are able to figure out what to do. and since its like a 20 minute delay in communications to the ships, it might not matter at all what you find ou tthat you have to figure out on the fly as they are approaching and be too late and only option you have is to jus tlet them forfill the given plan, knowing that every ship is gonna crash from bad landing conditions.
i realy think these two factors should be getting resolved first. thats gonna suck to see the day come to make the first attempt, just to see that my assumptions here were dead on the money as they very well may be. so then 26 fkn months later, adjustments can be made and attempt a 2nd landing. i donno. i jus tdon't want the first attempt and such to be a complete failure. that each attempt has a chance in hell and as of right now, it doesn't seem like thats gonna be the case. so we just gonna end up with bad news when the day finally comes. without a real sense of hope
They need to keep practicing till it works.
Great explanation! Incredibly excited, I'm not going..lol.
Their practicing on the old Moon landing set… 😀
Musk can take a step back and go …..
don't care what anybody says, i don't trust Musk
With the use of fusion—-
Need controlled ring of landing rockets near the apex of the rocket to use for braking and cushioned landing.
I'm waiting for the first successful temote landing band return from mars befor any thoughts of sending people there. How about a useful established lunar colony first
I think nasa wrong and space x knows what to do for landing.
I have the solution to this critical challenge. SpaceX and the Western world must prioritize building a self-sustaining space station equipped with a revolutionary gravity system. Each interconnected capsule should feature unlimited expansion capabilities to integrate future technologies seamlessly. This space station is not just an opportunity but a necessity—it will revolutionize medicine, accelerating drug development by tenfold with the power of AI.
While we construct this space station, robots must take the lead in building a Mars-ready city, tested to survive the planet's brutal conditions. We have the technology today to send robots, sparing human lives from the dangers of radiation, extreme temperatures, and the unknown threats lurking on Mars.
Failure to act decisively now risks putting humanity's future in jeopardy. The resources and knowledge we gain will determine whether humanity can survive off Earth—or be doomed to extinction when disaster inevitably strikes our planet. By embracing this bold plan, we save trillions of taxpayer dollars, countless lives, and secure the survival of the human race.
The clock is ticking, and the stakes couldn’t be higher. Will we rise to the challenge or let our inaction seal humanity’s fate.
I expect a manned Mars mission is at least a decade away – possibly two.
Firstly, we need to get a few successful missions to the moon – even if they are only touchdown and takeoff type trips with little or no extra vehicle activity. The ability to do a few of these things will teach us a lot about new techniques and I expect that is the best way to test their concepts to a certain level.
At the same time, they need to send an unmanned, but full sized vehicle to Mars. If they can land something, re-launch it and get it back to this planet they can then think about manned missions.
I really appreciate your efforts! Just a quick off-topic question: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How can I transfer them to Binance?
Retro propulsion creates a high pressure protective bubble around the spacecraft at hypersonic speeds in low atmospheric pressures. They were worried about instability and control issues.
Why they need to send RC dozer and roller ahead of Starship! Build a landing pad that will reduce the amount of dust. Also send sheets of metal and place on the ground like we did in WW2 for Aircraft when building airstrips.
The most reliable is the landing technique used twice on the Viking 1 and 2 , the first successfull landings in all human history , its called propulsive landing using one radar altimeter and for the final vertical approach a four beam doppler radar, complete sucess
what about a self-opening landing pad, which can be developed on the earth, before the Mars mission?
We are decades away from landing on Mars
I thought this was a video about how Space X is providing data to help land on Mars, not a complete rundown the necessary resources / technologies for colonization. Way to pad out the runtime guys. smh
The biggest dilemma is how to sell land on Mars. Lol .
The first person to die on Mars will be born in about 20 years
You guys are looking at it the wrong way rocket engines is not the way magnetic using the planet’s gravity field to travel push pull land and launch . And to travel long distances folding space will cause problems it should be a magnetic vortex wormhole more control
