Did anyone really win WW1? who won ww1.
So far only three nations — the United States, China and the Soviet Union (USSR) — have successfully landed spacecraft. The U.S. has had nine successful Mars landings since 1976. This includes its latest mission involving the U.S. space agency NASA’s Perseverance explorer, or rover.
Mars is really the only planet that sits within the habitable orbit around our sun. … We’ve even landed several spacecraft on Mars, including the NASA Perseverance rover and China’s Zhurong rover currently moving around the planet and beaming back photos and other valuable information as we speak.
The Viking landers were the first spacecraft to land on Mars in the 1970s. Viking 1 and Viking 2 each had both an orbiter and a lander. On July 20, 1976 the Viking 1 Lander separated from the Orbiter and touched down on the surface of Mars.
Article II of the Outer Space Treaty states, “Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.” In short, nobody can claim ownership of Mars or land on Mars, or do so with any other …
Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. One key aspect of this would be water processing systems. Being made mainly of water, a human being would die in a matter of days without it.
The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft’s flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. … The remaining four fatalities during spaceflight were all cosmonauts from the Soviet Union.
In February, space policy expert and Arizona State University professor Greg Autry told Business Insider that Musk likely won’t reach Mars until at least 2029, with or without NASA’s help. Other space experts say Mars probably can’t sustain long-term human settlement at all.
China became the world’s second nation to deploy a vehicle on the surface of Mars when a solar-powered rover began an exploration for potential evidence of life. The Zhurong rover started roaming the Red Planet late Saturday morning Beijing time, Chinese authorities said.
Mars will be colonized by humans by the year 2050, as long as autonomous mining processes quickly become more commercially viable. That’s the view of Professor Serkan Saydam from UNSW Sydney in the wake of the amazing landing on Mars by NASA’s Perseverance rover.
The world’s primary feudal landowner is Queen Elizabeth II. She is Queen of 32 countries, head of a Commonwealth of 54 countries in which a quarter of the world’s population lives, and legal owner of about 6.6 billion acres of land, one-sixth of the earth’s land surface.
No, people cannot legally buy planets, at least for now. There isn’t any way to legally enforce a claim to a planet, and courts have rejected similar claims in the past. International law forbids countries from claiming any celestial body, meaning a nation cannot grant space real estate to its citizens.
The mission is expected to cost $2.7 billion, rising to $2.9 billion when inflation is factored in. Despite the seemingly high cost, Perseverance is only the third most expensive Mars mission, trailing Viking 1 & 2 and the Curiosity rover.

Temperatures on Mars average about -81 degrees F. However, temperature’s range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F.
Growing a tree on Mars will surely fail with time. The Martian soil lacks nutrients for soil growth and the weather is too cold to grow a tree. … The conditions of Mars do not affect Bamboos because the Martian soil serves as a support for them, and it doesn’t need enough nutrients for it to grow.
Long-term exposure causes multiple health problems, one of the most significant being loss of bone and muscle mass. Over time these deconditioning effects can impair astronauts’ performance, increase their risk of injury, reduce their aerobic capacity, and slow down their cardiovascular system.
But the atmosphere on Mars is about 100 times thinner than Earth’s. That means less potential for drag, so it isn’t possible to land safely without some kind of aid.
All three of those stages have been carried out for the Moon, Venus, Mars, Jupiter, Saturn, a comet, and several asteroids. Several Soviet and U.S. robotic spacecraft have landed on Venus and the Moon, and the United States has landed spacecraft on the surface of Mars.
there are no hours in space. an hour is a not too convenient unit that is 1/24th of one revolution by the earth on its axis of rotation. Earth gravity is not that strong so it should only dilate time by a little bit.
Astronaut Thomas Jones said it “carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous.” Tony Antonelli, another space-walker, said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time, when I …
The pay grades for civilian astronauts are GS-11 through GS-14, based on academic achievements and experience. Currently, a GS-11 astronaut starts at $64,724 per year; a GS-14 astronaut can earn up to $141,715 in annual salary [source: NASA].
We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. … And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.

The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
Nasa Mars mission application process: One must be 30-35 years old with a Master’s degree in a science, engineering, or math field or pilot experience. He/she should be in good physical health with no dietary issues and not prone to motion sickness. Only American citizens or permanent US residents are eligible.
“We don’t want to be one of those single planet species, we want to be a multi-planet species,” Musk said on Friday, speaking after the company launched its Crew-2 mission to orbit. … And then build a city on Mars to become a spacefaring civilization, a multi-planet species,” Musk also said.
On April 23, SpaceX’s Crew-2 mission launched four more astronauts to the International Space Station aboard the company’s Crew Dragon spacecraft. … As recently as December, Musk stated publicly that it was possible that SpaceX would land humans on Mars by 2026.
The United States is the only country to have successfully conducted crewed missions to the Moon, with the last departing the lunar surface in December 1972.

It’s relatively cool with an average annual temperature of -60 degrees Celsius, but Mars lacks an Earth-like atmospheric pressure. Upon stepping on Mars’ surface, you could probably survive for around two minutes before your organs ruptured.
Because there’s no air, there’s no wind, which means no erosion. That’s made the dust particles on the lunar surface—called regolith—especially troublesome.
Overall, Mars is cold—its average global temperature is around -80 degrees Fahrenheit—and has a much thinner atmosphere than Earth. Because it has about a sixth of the pressure of Earth’s atmosphere, the planet doesn’t retain heat very long, causing temperatures to drop quickly.
Earth could not be bought, you have to trade something of roughly the same value. So far there is nothing of roughly the same value.
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
In fact, according to one astrophysicist who came up with a calculation for valuing planets, Earth is worth a bank-breaking $5 quadrillion dollars, unsurprisingly the priciest in the solar-system.
You may claim ownership of a planet by being the first person to travel there and plant your flag on it. However, you should be prepared for the possibility that others will not acknowledge your claim and, in the worst case, will fight with you over it.
“Outer space, including the Moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.”
They haven’t yet … but the fundamental legal regime is clear: Mars “belongs” to everyone—and therefore, in a practical way, to no one.
