Elon Musk just revealed the plans for SpaceX’s new Interplanetary Transport System — a giant spacecraft designed to carry humans to Mars and beyond. The idea behind this spacecraft, Musk said, is to make humans a multi-planetary species. At first, the ITS will carry about 100 people in one trip,but tickets will be very expensive.
SpaceX plans to build a “self-sustaining city” on Mars, company founder Elon Musk announced today. Here’s what we know about how they plan to do it.
Musk dropped the news during an address at the International Astronautical Congress meeting in Guadalajara, Mexico, where he had promised to reveal how the company planned to send people to Mars—and how it would keep them alive once they got there. Today, we finally got the first news of how he intended to do that.
“I don’t have an immediate doomsday prophecy,” said Musk, but noted that he saw only two possible paths forward. “One path is to stay on Earth forever and there will be some extinction event. The alternative is to become a multi-planetary species, which I hope you will agree is the right way to go.”
Is anybody out there? We might find out soon. The world’s largest radio telescope is now up and running in China, and it’s already searching for undiscovered stars and galaxies. It will take about three years to get the telescopes calibrated, but once it’s tuned up, it could help us discover one of astronomy’s greatest unsolved mysteries.
One of the most stunning and brightest galaxies of the northern hemisphere is M81, a classic grand design spiral galaxy with uniform swirling arms which measures two-thirds of the full-moon in diameter and lies 11.8 million light-years away in the circumpolar constellation of Ursa Major.
is one of the vital ingredients for life on Earth, scientists want to
know how it got here. One theory is that the water in our solar system
was created in the chemical afterbirth of the Sun. If that were the
case, it would suggest that water might only be common around certain
stars that form in certain ways. But a new study, published today in Science,
suggests that at least some of Earth’s water actually existed before
the Sun was born – and that it came from interstellar space.
That’s certainly something to ponder the next time you drink a glass
of water. But the discovery is also cool because it means water – and
maybe life – may be ubiquitous throughout the galaxy.
“If water in the early Solar System was primarily inherited as ice
from interstellar space, then it is likely that similar ices, along with
the prebiotic organic matter that they contain, are abundant in most or
all protoplanetary disks around forming stars,“ study author Conel
Alexander explained in a press release.
The researchers concluded that a significant portion of Earth’s water
came from interstellar space by looking at the relative abundance of
hydrogen and deuterium.
