What happens to a spacecraft once it dies?

When a spacecraft completes its mission or runs out of fuel, it’s sent to what NASA calls a Spacecraft Cemetery. Three thousand miles off the Eastern coast of New Zealand and more than 2 miles deep, it’s the one place farthest from any land mass on Earth.

The perfect spot to land giant chunks of spacecraft that are traveling more than 180 mph upon impact. NASA predicts the chance of a spacecraft hitting someone out here to be around 1 in 10,000.

How much would it cost to build a city on Mars? According to Elon Musk over the weekend, it could be the most expensive construction project in human history — and cost up to an eighth of the value of the entire global economy.

The SpaceX CEO’s vision includes not only sending the first humans to Mars, but to use that mission as a starting point to build a permanent settlement. Assuming all goes to plan, Musk believes that a self-sustaining city could take shape as early as 2050.

What happens after that point is anyone’s guess. Inverse has spoken to experts from a number of fields, who have flagged a series of issues those first inhabitants will need to address. They could mutate and develop new physical attributes, they could find the city’s confines stifling and develop a national identity, and they could develop a new, ground-up economy.

WASHINGTON — Blue Origin filed a protest with the U.S. Government Accountability Office on Monday challenging the Air Force’s plan to select two providers in the next procurement of launch services under the National Security Space Launch program.

Blue Origin, a rocket manufacturer and suborbital spaceflight company founded by Jeff Bezos, filed what is known as a “pre-award” protest with the GAO, arguing that the rules set by the Air Force do not allow for a fair and open competition.

“The Air Force is pursuing a flawed acquisition strategy for the National Security Space Launch program,” states a Blue Origin fact sheet that outlines the reasons for the protest.

’s two astronauts will one day fly to the International Space Station (ISS) onboard a SpaceX Crew Dragon capsule. The SpaceX spacecraft is a modified version of the Cargo Dragon capsule, the rocket manufacturer uses to deliver supplies to the ISS. Developed for NASA’s Commercial Crew Programme, part of SpaceX’s launch package includes sleek and futuristic spacesuits. But before NASA’s astronauts can take the Dragon into space, the two men had to go through a dress rehearsal of launch day operations.

The tardigrades were part of a “lunar library” that Spivack’s foundation had put together. According to Wired, the package was about the size of a DVD and contained human DNA—including Spivack’s own—as well as 30 million pages of information on mankind’s knowledge and thousands of dehydrated tardigrades.

Tardigrades are known as one of the toughest creatures on Earth. They are microscopic, measuring about 0.012 to 0.020 inches in length, and can withstand temperatures of up to 304 degrees Fahrenheit and can survive being frozen alive. One tardigrade is known to have survived being frozen for 30 years. They can also live without water for up to a decade by shriveling up and placing themselves in a state of suspended animation—a trait DARPA is currently studying in the hope of preserving soldiers injured on the battlefield.

(CNN)You’ve heard of men on the moon — but what about moss piglets?

Thousands of tardigrades – also known as “water bears” or “moss piglets” — were on board the Beresheet spacecraft when it crash landed on the moon in April.
The tiny creatures are incredibly hardy and can survive extremely low temperatures and harsh conditions– and The Arch Mission Foundation, which sent them into space, believes some may have survived.
Tardigrades are pudgy little animals no longer than one millimeter. They live in water or in the film of water on plants like lichen or moss, and can be found all over the world in some of the most extreme environments, from icy mountains and polar regions to the balmy equator and the depths of the sea.

In an attempt to create a “Noah’s ark” or a “back-up” for the Earth, non-profit organization The Arch Mission sent a lunar library — a stack of DVD-sized disks that acts as an archive of 30 million pages of information about the planet — to the moon. Along with the library, Arch Mission sent human DNA samples and a payload of tardigrades, which had been dehydrated, into space.
“We chose them because they are special. They are the toughest form of life we know of. They can survive practically any planetary cataclysm. They can survive in the vacuum of space, they can survive radiation,” Nova Spivack, co-founder of the Arch Mission Foundation, told CNN.
Tardigrades have eight legs with claws at the end, a brain and central nervous system, and a sucker-like pharynx behind their mouth, which can pierce food.
The Arch Mission put the creatures into a state of “suspended animation,” where the body dries out and the metabolism slows to as little as 0.01% of its normal rate.
The Arch Mission also sent a 30 million-page library along for the ride.

“In that state you can later rehydrate them in a laboratory and they will wake up and be alive again,” Spivack explained.
Although the animals won’t be able to reproduce or move around in their dehydrated state — if they have survived the crash — if rehydrated they could come back to life years later.
“We don’t often get a chance to land life on the moon that we decided to seize the day and send some along for the ride,” Spivack added.
Researchers hope that along with the tardigrades, the majority of the information from the lunar library survived the impact of the crash — and could be used to regenerate human life in millions of years.
“Best-case scenario is that the little library is fully intact, sitting on a nice sandy hillside on the moon for a billion years. In the distant future it might be recovered by our descendants or by a future form of intelligent life that might evolve long after we’re gone,” Spivack said.
“From the DNA and the cells that we included, you could clone us and regenerate the human race and other plants and animals,” he added.
