How long does it take to go to Mars in light years?

Just divide the time in seconds light takes between Earth and Mars, by the number of seconds within one year: 365. 25×24×60×601333=4. 2×10−5 light years. Hence, there is 2 . 63 × 10 – 5 light years of distance between Mars and Earth. The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year. According to NASA (opens in new tab), a one-way trip to Mars would take about nine months. If you wanted to make it a round-trip, all in all, it would take about 21 months as you will need to wait about three months on Mars to make sure Earth and Mars are in a suitable location to make the trip back home.

Do we age slower on Mars?

Training on the simulated martian terrain of Mars-500. Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth. It’s estimated that the heart, blood vessels, bones, and muscles deteriorate more than 10 times faster in space than by natural aging.

How long ago was Mars like Earth?

We Asked a NASA Scientist – Did Mars Ever Look Like Earth? When the solar system settled into its current layout over four billion years ago, Mars and Earth formed from the same materials and looked very similar. Both are terrestrial planets, with a central core, a rocky mantle, and a solid crust. Venus and Mars are the most like Earth, but in different ways. In terms of size, average density, mass, and surface gravity, Venus is very similar to Earth. But Mars is the planet that is most similar to Earth in other ways. If Mars possessed an Earth-like biosphere in the past, Mars may contain subsurface deposits of oil and natural gas indicating past life. Life might still exist in these deposits.

How many galaxies are there?

The Hubble Deep Field, an extremely long exposure of a relatively empty part of the sky, provided evidence that there are about 125 billion (1.25×1011) galaxies in the observable universe. Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across. When we take all of the available data together, we arrive at a unique value for everything together, including the distance to the observable cosmic horizon: 46.1 billion light-years. The observable Universe might be 46 billion light years in all directions from our point of view,… The Hubble Space Telescope has found not one or two, but as many as 6 galaxies that are dead, as far as their role of birthing stars is concerned. The Hubble Telescope was looking back in time to a period when the universe was some 3 billion years old. In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
