TESS Shares 1st Science Image in Hunt to Find New Worlds
NASA’s Transiting Exoplanet Survey Satellite, which began science operations in July, has released its first full frame image using all four of its cameras.
Devastating solar storm is a matter of ‘when not if’ warns Met Office as Solar Orbiter begins testing
A devastating solar storm which could wipe out communications on Earth and fry power grids is a matter of ‘when not if’ the head of the Met Office’s Space Weather Monitoring centre has warned.
Extreme space weather has already caused widespread disruption, with a geomagnetic storm leaving six million people without power in 1989 while Apollo astronauts narrowly missed being exposed to deadly radiation in 1972 and solar flares in 2003 forced the crew of the International Space Station to take cover.
The largest solar storm ever recorded, The Carrington Event in 1859, knocked out Telegraph systems and even set fire to paper in offices.
Mars-Moon Lava Tube habitation simulation in Iceland
Mike Dunn talked about the use of lava tubes for the Moon and Mars habitats. Mike has worked on The Mars Lava Tube Pressurization Project’s (MLTPP).
These Stunning Designs Show What Our Future on Mars Might Look Like
A recent contest challenged participants to create utopian designs of future human Mars settlements, and their creations are stunning.
In the HP Mars Home Planet Rendering Challenge, over 87,000 people from all over the world flexed their creative muscles to design the perfect colony on the Red Planet. Last summer, when HP launched the challenge, the participants started working on their designs, and the winners were announced on Aug. 14.
This challenge wasn’t just about creating a pretty, futuristic-looking, idealistic Martian colony. Indeed, the designs also had to show how the settlements would support 1 million colonists. The surface of the Red Planet is harsh, with an extremely thin atmosphere, intense radiation and dust storms that occasionally envelop the planet.

This Is What Happens When Planets Collide
Could a planet ever collide with Earth?
The universe is a big place, so when we get beautiful images from NASA’s Hubble Space Telescope, they cover a very small spot in the sky that may not fully represent what the universe at large looks like
The universe is a big place, so when we get beautiful images from NASA’s Hubble Space Telescope, they cover a very small spot in the sky that may not fully represent what the universe at large looks like. To change that, we’re expanding our view by significantly enlarging the area covered around huge galaxy clusters previously seen to get a better look at the universe.

Scientists Say We Can’t Terraform Mars. Elon Musk Says We Can
SpaceX’s CEO shrugs off 20 years of NASA research.
SORRY, ELON. To be ready for human occupants, Elon Musk has long called Mars a “fixer-upper of a planet.” But according to a new NASA-sponsored study, a better description might be a “tear-down.” The scientists behind that project say it’s simply not possible to terraform Mars — that is, change its environment so that humans can live there without life support systems — using today’s technology.
BUILDING AN ATMOSPHERE. Mars has a super thin atmosphere; a human unprotected on the surface of Mars would quickly die, mostly because there’s not enough atmospheric pressure to prevent all your organs from rupturing out of your body (if you survived a little longer, you could also suffocate from lack of oxygen, freeze from low temperatures, or get fried from too much ultraviolet radiation).
This study, published Monday in the journal Nature Astronomy, considers how difficult it would be to increase the atmospheric pressure on the Red Planet enough so that humans can walk on Mars’s surface without a pressurized suit and, ideally, without a breathing apparatus.
