Scientists Fired Tardigrades From A Gun To See If They Could Survive Space Travel

Tardigrades, microscopic invertebrates also known as water bears and moss piglets, are found virtually everywhere where liquid water exists, from droplets on leaves to ponds.

The tardigrades survived up to and including an impact velocity of 825 meters per second, equivalent to a shock pressure of 1.14 gigapascals. The surviving animals needed more than 8 to 9 hours to resume activity, suggesting at least some tissue damage.

Beresheet crashed on the Moon with a maximum velocity of 946 meters per second, casting severe doubts on the idea of tardigrades surviving the crash. But if a meteorite had a lower impact speed, survival may be possible.

Warp Drives and Negative Energy: Physicists Give Chances of Faster-Than-Light Space Travel a Boost

Faster than light travel is the only way humans could ever get to other stars in a reasonable amount of time. Credit: NASA

The closest star to Earth is Proxima Centauri. It is about 4.25 light-years away, or about 25 trillion miles (40 trillion km). The fastest ever spacecraft, the now-in-space Parker Solar Probe will reach a top speed of 450,000 mph. It would take just 20 seconds to go from Los Angeles to New York City at that speed, but it would take the solar probe about 6,633 years to reach Earth’s nearest neighboring solar system.

The New Space Race Will Be Run by Robots - Nextgov

As robots have advanced in both artificial intelligence and capabilities, people have started to fear that their jobs could be replaced by them. I have written about this several times in my Nextgov columns. And many other reporters and writers have covered this same topic.

That is unless your job of choice happens to be an astronaut. Not to disappoint kids or steer them away from one of the most popularly picked potential careers, but the future in this area belongs to robots. Yes, NASA is still foraging ahead with the Artemis Project , which aims to put people on the moon by 2024 as a stepping stone to Mars. But given the risks of space travel versus the potential rewards, it seems like robots are better suited for this role.

First NASA flight director's mission control mementos at auction | Space

The original headset used by NASA's first flight director has been given the "go" to proceed to auction .

"A valid argument can be made that Chris Kraft was as important to the growth and success of NASA as anyone in its history," Brad Palmer, Heritage Auctions' space exploration consignment director, said in a statement. "He was the director of the Johnson Space Center for a decade during a crucial time in NASA's history, and came up with the concept of NASA's Mission Control, which now bears his name ."

To the moon...literally: Should you buy into the future of space travel?

By Robert Francis, Australian Managing Director of global multi-asset investment platform eToro

The hype is well and truly present for SpaceX, as it recently launched and successfully landed its futuristic Starship, finally nailing a test flight of the rocketship that Musk intends to use to land astronauts on the moon and send people to Mars.

But what about other key players currently shaping this space? Should investors keep watch of space stocks and listed companies leading the odyssey to outer space, or could it suck them into a black hole?

The Edge Episode 12: 2021, A Space Hotel Odyssey | California Magazine

Space. The final frontier. Since the first human left Earth's atmosphere in 1961, few earthlings—and even fewer private citizens—have had the opportunity to "boldly go" there. But, with new advancements from SpaceX, Blue Origin, and other spaceflight companies, wealthy tourists could soon be booking rooms in hotels in outer space. As with any new industry, the rise of space tourism raises some new, sometimes uncomfortable, questions: Are we colonizing space?

This episode was written and hosted by Laura Smith and Leah Worthington and produced by Coby McDonald.

How Human Space Launches Have Diversified - Scientific American

We are entering a new era in sending people beyond Earth. After the Apollo moon program, U.S. space shuttles and Russian Soyuz flights were the only game in town. Those ferries carried astronauts to and from low-Earth orbit, where space stations Skylab, Mir and the ISS hung around the planet. Today there is far more diversity among launchers and destinations, says astronomer Jonathan C. McDowell of the Harvard-Smithsonian Center for Astrophysics.

How Far From Earth Can Humans Travel Into Space? | IFLScience

As of 2021, Americans James Lovell, Fred Haise, John Swigert are the three people who have traveled furthest from Earth, during the Apollo 13 mission. When they flew behind the Moon, they were 400,171 kilometers (248,655 miles) from the surface of the Earth. Light takes 1.335 seconds to cover that distance.

Many of us have certainly fantasized about going into the stars, or at least exploring the solar system. The feasibility of doing that safely is still slightly out of reach, but we are certainly striding towards further and further forays away from the comfort and safety of our own planet.
