When we talk about the enormity of the cosmos đ«, itâs easy to toss out big numbers â but far more difficult to wrap our minds around just how large, how far, and how numerous celestial bodies really are. Join us for a cosmic journey to see the size of our Milky Way galaxy: https://go.nasa.gov/2UxkHIN

The worldâs largest plane just flew for the first time
Posted by Heather Blevins in categories: space, transportation
After years of development in the desert north of Los Angeles, a gigantic, six-engined mega jet with the wingspan of an American football field flew Saturday morning for the first time.
âWe finally did it,â said Stratolaunch Systems CEO Jean Floyd at a news conference from the hangar at Mojave Air & Space Port. âIt was an emotional moment to watch this bird take flight.â
Stratolaunch, the company founded in 2011 by the late Microsoft co-founder Paul Allen, conducted the first test flight of the worldâs largest plane.

Environmentalists are Wrong: Nature Isnât Sacred and We Should Replace It
Posted by Zoltan Istvan in categories: biotech/medical, ethics, food, information science, life extension, robotics/AI, space, sustainability, transhumanism
Environmentalism and climate change are increasingly being pushed on us everywhere, and I wanted to write the transhumanism and life extension counter argument on why I prefer new technology over nature and sustainability. Hereâs my new article:
On a warming planet bearing scars of significant environmental destruction, youâd think one of the 21st Centuryâs most notable emerging social groupsâtranshumanistsâwould be concerned. Many are not. Transhumanists first and foremost want to live indefinitely, and they are outraged at the fact their bodies age and are destined to die. They blame their biological nature, and dream of a day when DNA is replaced with silicon and data.
Their enmity of biology goes further than just their bodies. They see Mother Earth as a hostile space where every living creatureâbe it a tree, insect, mammal, or virusâis out for itself. Everything is part of the food chain, and subject to natural law: consumption by violent murder in the preponderance of cases. Life is vicious. It makes me think of pet dogs and cats, and how itâs reported they sometimes start eating their owner after theyâve died.

The First Group of Female Cosmonauts Were Trained to Conquer the Final Frontier
Posted by Genevieve Klien in categories: military, space
In early 1962, members of the male space squad gathered at a dining room in Star City and were joined by Yuri Gagarin. âCongratulations! Get ready to welcome the girls in a few days,â announced Gagarin.
âWe, a tiny group of military test pilots selected for the space program, had been living together as one big family in Star City for two years. We shared struggles and knew everything about each other, and now we had to accept new members to our family,â recalled cosmonaut Georgi Shonin.
âWhen we started training together, it was very unusual to hear soft and feminine call signs Chaika (seagull) or Bereza (birch) instead of solid and firm Sokol (falcon) or Rubin (ruby),â Shonin continues. âTheir intonations alone were telling. If a voice was sonorous, everything went as planned. But sometimes their voices sounded pitiful. That meant the instructor was practicing certain failures of the system with them, and Bereza or Chaika was trying to fix the problem.â

Strange anti-ageing effect of space travel discovered in NASAâs Twin Study
Posted by Genevieve Klien in categories: biotech/medical, life extension, space
When NASA set out to study identical twin astronauts, leaving one on Earth and sending the other to the International Space Station (ISS) for a year, they expected that the rigours of microgravity would have largely negative impacts.
But on board the ISS, Scott Kelly, 51, underwent a very strange transformation which has left scientists scratching their heads.
The telomeres in his white blood cells got longer. Telomeres are the protective caps which sit at the end of chromosomes, protecting the DNA inside, like the plastic aglets on the end of shoelaces.

This moss-covered wall is as air-purifying as 275 urban trees
Posted by Quinn Sena in categories: environmental, health, space, sustainability, transportation
From smog-sucking bikes to electric taxis and paint made of car exhaust, designers and architects are stepping up to address air pollutionâthe worldâs single largest health risk. But a new air filter making the rounds in Oslo, Paris, Brussels, and Hong Kong shows that nature may be our best ally in this battle.
Essentially a moss-covered wall, each CityTree removes CO2, nitrogen oxides, and particulate matter from the air while also producing oxygen. A single tree is able to absorb 250 grams of particulate matter a day and remove 240 metric tons of CO2 each yearâa level roughly on par with the air purification impact of 275 urban trees. Thirteen feet tall, with a metal frame, the CityTrees are easily installed in a public space, and they even have built-in seating at their base.

Surviving Mars: Green Planet expansion allows you to terraform Mars
Posted by Quinn Sena in categories: engineering, environmental, space
Terraforming is coming to Surviving Mars in a spectacular way. Not only can you make the atmosphere breathable for humans, but it also allows you to engage in new mechanics previously absent from the experience.
