Leik Myrabo (then at Rensselaer Polytechnic Institute) was, at about the same time, performing experiments with lasers at Wright-Patterson Air Force Base in Ohio. When you think about the problems of laboratory work on these matters, consider the fact of gravity, meaning that you are working in a 1 g gravity well with diaphanous materials whose acceleration depends on how hot you can allow them to become.

Is Earth the only known planetary body with life on it?

How Can We Protect Alien Life From Us—and Us From It?

Nope. In fact, there are 96 bags of human waste on the lunar surface. These were left over by the Apollo astronauts and contain literally billions of microbes from Earth—massively irradiated and (most likely) dead, of course. 2nd-Known Interstellar Visitor May Have Breezed Through Our Solar System. At first, it was just another bright, fuzzy speck in the sky.

2nd-Known Interstellar Visitor May Have Breezed Through Our Solar System

But it may turn out to be something much more exciting: the second known object to hurtle through our solar system after leaving another system. Astronomers will need a lot more observations before they can be confident giving the comet that title, but early data about the object seems promising. That would make the comet, currently known as Comet C/2019 Q4 (Borisov) after the person who first spotted it, the first traveling successor to the interstellar object 'Oumuamua, which was discovered in October 2017. Think Living Spaceships Are Science Fiction? Think Again.

Going interstellar is hard.

Think Living Spaceships Are Science Fiction? Think Again

The closest stars to the sun are generally several light-years away, so a trip would take decades at best. Not to mention that the road there is perilous: Particle impacts and radiation can easily destroy a mission on its way there. Angelo Vermeulen, however, likes hard problems. He has imagined a spacecraft dug into an asteroid, which evolves like an organism and could take us beyond the solar system.

The best part? The European Space Agency (ESA) is studying how organisms like fungi survive in the face of extreme radiation, such as after the Chernobyl nuclear disaster, to better prepare human space flights against ionizing radiation beyond the Earth’s protective magnetic field. Centauri Dreams — Imagining and Planning Interstellar Exploration. What Happens to the Brain in Low Gravity? NASA has made a commitment to send humans to Mars by the 2030s.

What Happens to the Brain in Low Gravity?

This is an ambitious goal when you think that a typical round trip will anywhere between three and six months and crews will be expected to stay on the red planet for up to two years before planetary alignment allows for the return journey home. It means that the astronauts have to live in reduced (micro) gravity for about three years – well beyond the current record of 438 continuous days in space held by the Russian cosmonaut Valery Polyakov.

In the early days of space travel, scientists worked hard to figure out how to overcome the force of gravity so that a rocket could catapult free of Earth’s pull in order to land humans on the Moon. Today, gravity remains at the top of the science agenda, but this time we’re more interested in how reduced gravity affects the astronauts’ health – especially their brains. A New Kind of Propulsion System That Doesn't Need Propellant. It Converts Electricity into Thrust and Vice Versa. Some of the best things in science are elegant and simple.

A New Kind of Propulsion System That Doesn't Need Propellant. It Converts Electricity into Thrust and Vice Versa.

A new propulsion system being developed in Spain is both those things, and could help solve a growing problem with Earth’s satellites: the proliferation of space junk. Researchers at Universidad Carlos III de Madrid (UC3M) and the Universidad Politécnica de Madrid (UPM) in Spain are patenting a new kind of propulsion system for orbiting satellites that doesn’t use any propellant or consumables. The system is basically a tether, in the form of an aluminum tape a couple kilometers long and a couple inches wide, that trails out from the satellite.

If We Don't Act Soon, Space Junk Might Trap Us On Earth. Not everything we send into space comes back down.

If We Don't Act Soon, Space Junk Might Trap Us On Earth

In fact, there are millions of pieces of junk, ranging from tiny flecks of paint to entire satellites currently taking up space around the Earth's atmosphere. As of now, space agencies are already tracking 750,000 pieces of space debris orbiting the Earth. This space pollution is a major problem--because of how fast objects orbiting Earth travel, even a paint fleck a few millimeters long can cause serious damage when it hits something.

The electrodynamic tether, or EDT, is made with the help of 106-year-old fishing net company Nitto Seimo. The Japanese space program, JAXA, plans to launch EDT as "a promising candidate to de-orbit the debris objects at low cost. " 7 ways a trip to Mars could kill you. Time-lapse video shows inflatable BEAM space habitat coming to life. It took a couple of attempts, but over the weekend NASA successfully inflated the Bigelow Expandable Activity Module (BEAM) attached to the International Space Station (ISS).

In case you weren't onsite with seven-plus hours to spare, NASA has released a handy time-lapse video that shows the module grow to full size. Five key findings from 15 years of the International Space Station. The International Space Station is the longest-running continuously inhabited human outpost in space – this year it celebrated its 15th anniversary. As the ISS orbits the Earth it is essentially in a state of free fall, counteracting the Earth’s gravity and providing an ideal platform for science in space. Science aboard the ISS is decidedly cross-disciplinary, including fields as diverse as microbiology, space science, fundamental physics, human biology, astronomy, meteorology and Earth observation to name a few.

But let’s take a look at some of the biggest findings. 1. The fragility of the human body. Why Blue Origin's Rocket Landing Is Big News For Space Travel. Eight objects that define the Soviet space race. EmDrive Back in the News. Martin Tajmar’s presentation at the American Institute of Aeronautics and Astronautics’ Propulsion and Energy Forum and Exposition in Orlando yesterday has been getting plenty of press. Tajmar is looking at the device now commonly called an EmDrive, studied by Sonny White’s team at Eagleworks (Johnson Space Center) and advocated by Roger Shawyer, Guido Fetta and Chinese experimenters as a way of producing thrust in a way that seemingly violates conservation of momentum. Tajmar (Dresden University of Technology) offers a paper entitled “Direct Thrust Measurements of an EmDrive and Evaluation of Possible Side-Effects” in his presentation on apparent thrust produced by the test device. As he told WIRED (which announced that The ‘impossible’ EmDrive could reach Pluto in 18 months), the current work will not close the story.

From the paper itself: Image: Physicist Martin Tajmar. Will that happen here? Aerospace Engineers Warn First-Grader’s Design For Spaceship Completely Unsafe - The Onion - America's Finest News Source. MONROEVILLE, PA—Listing off a litany of structural and technological flaws, the nation’s leading aerospace engineers issued a stern warning Thursday that local 6-year-old Bradley Koenig’s design for a spaceship is entirely unsafe. Experts from the fields of aerodynamics, jet propulsion, and control engineering unanimously confirmed that the orange-and-purple rocket ship, which Koenig drew during Mrs. Silvestri’s first-grade class, not only raises major safety concerns, but could compromise the lives of everyone on board were it to ever go to launch. “I can’t even begin to enumerate all the safety protocols and fundamental principles of spaceflight that this particular vehicle violates,” said veteran NASA flight director Raymond Fletcher, who called the crayon-drawn spaceship the “most poorly conceived” and “shockingly hazardous” craft he had ever encountered.

“The asymmetrical oval shape of the craft alone would likely cause it to break apart upon reentry into Earth’s atmosphere. Space travel may be bad for your brain – here's why. There is bad news for those planning to go to Mars in the near future: a study in mice has suggested that radiation in space could cause cognitive decline in astronauts. However, we know from past research that mental, social and physical exercise can boost cognitive functions. With planned Mars missions moving ever closer, it might be be worth exploring activity as a way to counter radiation damage. There are many hurdles to overcome to get to Mars. The obvious one, of course, is the amount of time it takes – about eight months.

But for those brave enough to attempt such a journey, this may well be acceptable. 15 Ongoing Space Missions You Should Know About. NASA Eyes Crew Deep Sleep Option for Mars Mission.
