Space radiation reproduced in the lab for better, safer missions
Human-made space radiation has been produced in research led by the University of Strathclyde, which could help to make space exploration safer, more reliable and more extensive.
Researchers used novel laser-plasma-based accelerators to mimic the radiation, which presents a risk to astronauts and space technology owing to the lack of protection from it in space.
The study, funded by the European Space Agency (ESA), shows for the first time that this type of device can be used for realistic space radiation reproduction and testing on Earth.
The research, published in Scientific Reports, also involved researchers and R&D capabilities at ESA, Heinrich-Heine-University Düsseldorf, the Central Laser Facility – where the radiation tests were carried out – the University of Hamburg, Leibniz Supercomputing Centre and the University of California Los Angeles.
This morning, a plucky NASA spacecraft has entered the orbit of one of the oddest little worlds in our solar system.
Ceres is round like a planet, but really small. Its total surface would cover just a third of the United States. And there’s still a lot of work to be done in order to learn how Ceres fits into our solar system.
Nearby star is a good model of our early solar system
NASA’s SOFIA aircraft, a 747 loaded with a 2.5-meter telescope in the back and stripped of most creature comforts in the front, took a big U-turn over the Pacific west of Mexico.
The Stratospheric Observatory for Infrared Astronomy aircraft was just beginning the second half of an overnight mission on Jan. 28, 2015. It turned north for a flight all the way to western Oregon, then back home to NASA’s Armstrong Flight Research Center in Palmdale, California. Along the way, pilots steered the plane to aim the telescope at a nearby star.
NASA has released the closest images it has of dwarf planet Ceres, the largest object in the asteroid belt between Mars and Jupiter. The photos were captured in the Dawn spacecraft’s last orbit. Ceres has 130 bright spots on its surface — and scientists seem to have figured out why.
Scientists exit Hawaii dome after yearlong Mars simulation
Six scientists have completed a yearlong Mars simulation in Hawaii, where they lived in a dome in near isolation. For the past year, the group has lived in the dome on a Mauna Loa mountain and could go outside only while wearing spacesuits.
On Sunday, the simulation ended, and the scientists emerged.
Space. The empty black vacuum became a little bit brighter on
Sunday after Scott Kelly, a U.S. astronaut aboard the International
Space Station, tweeted an image of the first flower ever grown in space. The flower is part of a larger experiment on the potential for vegetation in
low-gravity environments, with the ultimate objective to grow
vegetables. Kelly tweeted out a pretty funny Matt Damon joke too.
On Monday, NASA administrator Charles Bolden applauded President Barack Obama’s proposed $18.5 billion 2016 NASA budget, which proposes
raising the agency’s budget by $519 million over 2015 levels. While
scientists and researchers may be overjoyed with the Obama
administration’s renewed financial commitment to the space agency, space
lovers of all stripes have something else to celebrate: $30 million for the initial stages of a mission to Jupiter’s moon of Europa.
NASA’s Kennedy Space Center is the country’s busiest space port, with about 30 launches scheduled so far this year. It hosts commercial companies like SpaceX and United Launch Alliance, and sees over one million yearly visitors who come to watch launches and learn about space and climate science. How climate change could utterly disrupt it.
Signs the private Mars One colonization mission is a scam:
It said it received 200,000 applications, actually received 2,761.
Applications used a “point” ranking system and the only way to gain more points after the initial review process was to buy merchandise, donate money or convince their friends and family to contribute.
Mars One asked all contestants to donate 75% of any speaking fees to the mission.
The top 10 candidates for the mission were those who had contributed the most funds to Mars One.
The first ( seen in the first animation) took place on September 7 and the second one on the second of November. They were initially thought to be some plane crashes, but were later confirmed to be small meteor showers.
Just that you know this happens all the time in our atmosphere and there is nothing to be alarmed about.
Here is yet another spectacular but dangerous meteorite crash in Russia that occurred waay back in 2012. Caused quite a stir!
It might sound like science fiction, but we already know how
to make objects move at near light speed. Physicists do it all the time
inside particle accelerators, where they accelerate particles to
relativistic speeds just a small fraction below the speed of light (about 186,000 miles per second).
we try to reach these speeds on a macro scale, we run into all kinds of
problems. Now researchers are saying a new kind of laser-based propulsion would eliminate the need for fuel and could accelerate spacecraft up to 26% of the speed of light. At that blistering pace, a tiny space probe could get to Mars in just 30 minutes. The technology to make it happen already exists.
SCIENCE: There was excitement today as NASA announced that Edward Burns was the first dickhead big enough to be visible from space.
“This is amazing news.” confirmed Dr. Juan Kerr, Pointless Letters science consultant. “A dickhead big enough and obvious enough to be visible to the crew of the ISS as they pass over. This will redefine our understanding of just how big a dickhead someone can be.”
