NASA creates prototype flying saucer for mission to Mars

Landing ever larger vehicles on the Martian surface has posed many challenges over the years due to it’s extremely thin atmosphere which provides very little air resistance to slow down incoming spacecraft. So, in an effort to increase drag forces and allow for heavier lander missions, NASA is testing out a a totally new saucer shaped re-entry vehicle.



Behold the first geological map of Ganymede, Jupiter’s largest moon

by Lauren Davis

Four hundred years ago, Galileo Galilei observed Ganymede in orbit around Jupiter. This week, a team of planetary scientists unveiled the first global geological map of our solar system’s largest moon.

Using images obtained by NASA’s Voyager 1 and 2 spacecraft and the Galileo orbiter, a team led by Geoffrey Collins of Wheaton College pieced together a mosaic image of the planet, giving us our first complete image of the geological features of the satellite. Above, you can see the moon centered at 200 west longitude. The darker areas represent the very old and heavily cratered region of Ganymede, while the lighter areas are somewhat younger regions marked with grooves and ridges…

CERN | Anna Pantelia

CERN is the European organization for Nuclear research and it’s considered the biggest particle physics experiment. it’s located at geneva and scientists, engineers and students from 113 nationalities are hosted. 29 September of 1954 was the ratification of this organization by 12 countries in Europe. Several important achievements have been made during experiments at CERN with the most important the development of World Wide Web.

This is the AWWA Sky Whale, a concept for the next generation of aircraft. 

It is supposed to incorporate next gen technology and materials to create a ‘greener’ aircraft, despite having three stories of passenger seating and a fuselage twice as wide as the largest planes today.

It’s engines will be hybrid, working off solar power as well as jet fuel. it has mechanisms to reduce drag, and thanks to lighter materials the entire airplane will be lighter despite its size. The jets will even be able to rotate up and down (like a harrier jet) to reduce the size of the needed runway.

The plane will be able to seat a total of 755 passengers and will incorporate all the luxuries you would expect to go with a plane that looks as amazing as that.

Design innovation helps tackle bridge corrosion


Structural steel in bridge design has one fatal flaw — bridges are usually over water, often over salt water, making failure through corrosion almost inevitable.

Even more frustrating, steel bridges usually corrode and weaken at the one place where inspection is costly and difficult, the gusset.

New York-based, HNTB Corp. national chief bridge engineer Ted Zoli had a better idea. Instead of doing what every engineer does and just focus on materials, he thought, why not focus on the design and try to eliminate some of the inevitable costs associated with bridge maintenance?





We literally have an entire trilogy of movies that explain why that is a bad idea.

I hate to disappoint any dinosaur lovers, but DNA fully decays after 1.5 million years… so anything older than that we can never get a usable sample from. Mammoths and other things living only thousands of years ago are still totally on the table tho.

Yesterday, the Library of Congress digitized a treasure trove of materials from Carl Sagan’s life—including early Cosmos drafts, NASA proposals, correspondences with Neil deGrasse Tyson, audio recordings, and over 30 minutes of home movie footage.

In lieu of this momentous occasion, they’ve also created a showcase of over 300 historic items exploring connections between the legacies of Carl, Galileo, H.G. Wells, and many others.
