SpaceX plans to send 100 passengers to Mars by 2024

SpaceX plans to send 100 passengers to Mars by 2024

SpaceX will begin building the first ships that will make the human voyage to Mars possible in nine months from now. Elon Musk announced Friday at the International Astronautical Congress in Adelaide, Australia, that his company will be able to send unmanned cargo ships to the red planet in 2022 and 100 explorers will make it to Mars by 2024.

Mars is sometimes located 54 million kilometers from Earth and other times at 401 million kilometers apart from us due to the planets’ constant motion as they rotate on their own and around the sun simultaneously.

The first unmanned cargo ships will be sent to deposit the components needed to build the first off-world colony and look for resources. Along with the crewed spaceship, another pair of cargo ships will be sent to establish the settlement.

Musk said at the world’s largest space conference that the upstart company has plans to use the Interplanetary Transport System to return to the Moon and also to settle rapid point-to-point passenger transportation on the astronomical body.


Sounds like a very ambitious timeline. My prediction is that no human will set foot on Mars by 2024.

I would say not even 2050.

For one thing, the launch window to go to Mars comes once every 26 months or so. I suppose it's possible at other times, but you are battling the laws of physics if you do so.

https://en.wikipedia.org/wiki/Exploration_of_Mars

The minimum-energy launch windows for a Martian expedition occur at intervals of approximately two years and two months (specifically 780 days, the planet's synodic period with respect to Earth).[9] In addition, the lowest available transfer energy varies on a roughly 16-year cycle.[9] For example, a minimum occurred in the 1969 and 1971 launch windows, rising to a peak in the late 1970s, and hitting another low in 1986 and 1988.[9]

Only if your goal is to minimize your delta-v requirements. If you want to minimize duration - which right now is our best way to minimize exposure to radiation and microgravity - then you use a less restrictive launch window that happens once in a little over a year.

Keep in mind that a longer duration would need more supplies than a shorter duration one. So a "less efficient" plan would need a higher ratio of fuel to payload, but also needs less payload. And months of life support & food counts for a lot of payload.

I predict no one on Mars by 2024 and SpaceX out of business.

A modest reminder:
Science Daily wrote:NASA’s Dirty Secret: Moon Dust

The Apollo Moon missions of 1969-1972 all share a dirty secret. “The major issue the Apollo astronauts pointed out was dust, dust, dust,” says Professor Larry Taylor, Director of the Planetary Geosciences Institute at the University of Tennessee. Fine as flour and rough as sandpaper, Moon dust caused ‘lunar hay fever,’ problems with space suits, and dust storms in the crew cabin upon returning to space.
[…]
The trouble with moon dust stems from the strange properties of lunar soil. The powdery grey dirt is formed by micrometeorite impacts which pulverize local rocks into fine particles. The energy from these collisions melts the dirt into vapor that cools and condenses on soil particles, coating them in a glassy shell.

These particles can wreak havoc on space suits and other equipment. During the Apollo 17 mission, for example, crewmembers Harrison “Jack” Schmitt and Gene Cernan had trouble moving their arms during moonwalks because dust had gummed up the joints. “The dust was so abrasive that it actually wore through three layers of Kevlar-like material on Jack’s boot,” Taylor says.

To make matters worse, lunar dust suffers from a terrible case of static cling. UV rays drive electrons out of lunar dust by day, while the solar wind bombards it with electrons by night. Cleaning the resulting charged particles with wet-wipes only makes them cling harder to camera lenses and helmet visors.

I'm confident the Martian environment will come up with its own idiosyncratic nastiness. :mrgreen:

Elon Musk owes his fortune to government subsidy of Tesla.

He is a high tech genius at being a welfare recipient.

They were ok in the 80s, but everything after their third album sucks.
"It is not I who is mad! It is I who is crazy!" -- Ren Hoek

"[... it seems most strange that... ] the Creator of Heaven and Earth resorted to the womb of a certain Jewish lady, grew there for nine months and was born as an infant, and afterwards grew up and was betrayed into the hands of his enemies who sentenced him to death and executed him, and that afterwards... he came to life and returned to his original place. The mind of a Jew, or any other person, simply cannot tolerate these assertions. If you have listened all your life to the priests who have filled your brain and the marrow of your bones with this doctrine, and it has settled into you because of that accustomed habit. [I would argue that if you were hearing these ideas for the first time, now, as a grown adult], you would never have accepted them." -- Rabbi Moses ben Nahman, defending the Talmud at the Disputation of Barcelona, July 1263.

But we will still go because we are driven by the very thing that has always driven waves of settlers since the dawn of civilization: the need to find a place that doesn't have taxes. Followed by the need to send out waves of settlers to tax them and their resources. We will explore this solar system, this galaxy, and this universe on the frontier of the taxation event horizon. Growing ever outwards at the speed of bureaucracy.

Hence why it might take a little while.

Perchlorates are reactive chemicals first detected in arctic Martian soil by NASA's Phoenix lander that plopped down on Mars over five years ago in May 2008. It is likely both of NASA's Viking Mars landers in 1976 measured signatures of perchlorates, in the form of chlorinated hydrocarbons.
...
The high levels of perchlorate found on Mars would be toxic to humans, Smith said.

"Anybody who is saying they want to go live on the surface of Mars better think about the interaction of perchlorate with the human body," he warned. "At one-half percent, that's a huge amount. Very small amounts are considered toxic. So you'd better have a plan to deal with the poisons on the surface."

Any humans exploring Mars, Smith said, will find it hard to avoid the finest of dust particles. "It'll get into everything…certainly into your habitat."

Probably couldn't entirely get rid of the dust itself, but maybe a chemical neutralizer in the airlocks or whatever separates the habitats from the outside? Would there be such a thing?

Pinging a chemist!!

That certainly exists – but to "live on Mars" you'd need an industrial basis to manufacture it.

You could just start with a plentiful supply, until you could manufacture your own?

Found this:

Edison! The man of electrical genius -- Earth's savior? After their devastating attack, the Martians have been defeated by disease . . . yet strange lights soon flicker again upon the Planet of War, signaling the beginning of a new attack upon a weakened and demoralized Earth. Then Thomas Edison announces the development of a new electrically-powered ship -- with which he has already visited the Moon. Earth may not need meekly await the next wave of the Martian invasion! In this amazing 1898 novel of cataclysm, invention, and adventure, early science-popularizer Garrett Serviss presents a startling future that might have been.

Musk is our Edison. :mrgreen:
