Terraforming Mars (PC Digital Download) Expired

Is there internet multiplayer for this?

This is Elon Musk's planet. We all know what his ultimate goal was.

What is your convincing proof that had you believe this reporting?
Oh, and its in the 70's for the claim of humans to land on moon.

Don't let the large distances fool you. The velocity change needed to go from the Earth's surface to an orbit, or from one orbit to another, is called delta-v. The delta-v needed to travel from the Earth's surface to low Earth orbit (LEO) is about 9.4 km/s (i.e. you need to end up traveling 9.4 km/s faster than you began). Delta-v from LEO to:

• geostationary transfer orbit is about 2.5 km/s. (That's an orbit which touches LEO at one end, and geostationary orbit at the other. Putting it in a circular geostationary orbit requires an extra 1.5 km/s, so about 4 km/s total from LEO. Geostationary orbit is where our communications satellites go.)
• reaching the Moon is about 3.1 km/s. (Landing on the Moon requires an additional 2.5 km/s.)
• reaching Mars requires about 3.6 km/s. (Landing on Mars requires another 5.4 km/s, but you can get most of that for free by aerobraking. However, you do have to pay for it if you launch from Mars, which is why most everything we've sent there so far has been one-way.)
• Jupiter is about 6.3 km/s.
• Saturn is about 7.3 km/s.
• Uranus is about 8 km/s.
• Neptune is about 8.25 km/s.
• leaving the solar system is about 8.75 km/s.

So it actually costs less delta-v to reach Mars, than to put a satellite into geostationary orbit, or to land on the Moon. It just takes longer to get to Mars, and you need better communications due to the greater distance. If you believe that we have communications satellites, then you also believe we can reach Mars, and that we have at least 90% the capability to land on the Moon.

Even without gravity assists, it costs less delta-v to get anywhere in the outer solar system (or to land on the Moon), than to reach LEO from the Earth's surface. In other words, if you take a rocket designed to reach LEO, disassemble it (and its fuel), launch it piece by piece into LEO, and assemble it there, that rocket can travel directly to any planet in the outer solar system, land on the moon (and get most of the way back to Earth), or even leave the solar system. Using gravity assists allows us to reach these other planets using even less rocket.

Going the other way (towards the sun) is actually harder. Mercury is the hardest planet to put something in orbit around (5.6 km/s delta-v needed to intersect its orbit, about 6.5-7.5 km/s more to match its speed around the Sun so you can orbit it). That's why we've only sent 3 spacecraft there. Living on Earth gives you a misguided sense that going "down" is easier than "up" - due to friction, the extra speed you pick up when going down can be dissipated for free on Earth. In space, there's no friction, so you have to pay with extra fuel if you want to match speeds with your surroundings at the end of your "down" trip.

Interesting info, though I have no idea why you're responding to my post...

Because he wants to list a bunch of junk science info with lots of calcs to make it sound believable. No one has gone to the moon 237K miles away let alone a light source we call mars that is falsely claimed to be 4 to 9 billion miles away. The ONLY limit of space IS your imagination! AND, its the ONLY way you can get there!

N A S A Orion project was supposed to try and allow humans to pass the Van Allen belts, but that is not possible. Its beyond the laws of earth realm. But that wont stop the theater they create, and new tax pools to take the publics money, with 50mil each day(over 20billion a year), and now SpaceForce. Notbody seams to notice, nobody seams to care....Mass psychosis is a thing.

Oriflop project. First they need to be accountable for their 'Moon Hoax of the Century' crime. I know, I know, 'that is not possible and beyond the laws of earth realm'. That's why they keep on producing morons from their high schools and such 'games'.

At least indoctrinated ranran ran off
