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.

Faster Than Light? Neutron-Star Merger Shot Out a Jet with Seemingly Impossible Speed

Scientists Say We Can’t Terraform Mars. Elon Musk Says We Can

Posted by in categories: biotech/medical, Elon Musk, engineering, environmental, space

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).

Last Delta II Rocket Launches NASA Satellite to Map Earth’s Ice with Space Laser

Posted by in category: space

A $1 billion NASA mission that will use a laser to track changing ice levels on Earth soared into space early Saturday (Sept. 15), launching into a predawn California sky on a mission that also marked the final flight of a record-setting rocket.

ISS hole: We will look back on Sept 2018

Posted by in categories: astronomy, ethics, habitats, space, space travel

Someday, people across the world will look back on September 2018, much like we look back on the terror attacks of 9/11 or the safe return of Apollo 13 in 1970. They are touchstone moments in world history. For Americans, they are as indelible as Pearl Harbor, the assassination of John F. Kennedy or the first moon landing.

So, what happened just now? The month isn’t even half over, and the only events we hear about on the news are related to Hurricane Florence and Paul Manafort. (In case you live under a rock or are reading this many years hence, the hurricane made landfall on the coast of the Carolinas, and the lobbyist / political consultant / lawyer / Trump campaign chairman pled guilty to charges and has agreed to cooperate in the continuing Mueller investigation).

No—I am not referring to either event on the USA east coast. I am referring to a saga unfolding 254 miles above the Earth—specifically a Whodunit mystery aboard the International Space Station (ISS). NASA hasn’t seen this level of tawdry intrigue since astronaut Lisa Marie Nowak attacked a rival for another astronaut’s affection—driving across the country in a diaper to confront her love interest.

So What is the Big Deal This Week?!

Watch the Last Delta II Rocket Carry ICESat-2 Into Space

Posted by in category: space

Godspeed, Delta II.


NASA’s last Delta II rocket blasted into the atmosphere from Vandenberg Air Force Base in California on Saturday carrying the Ice, Cloud and land Elevation Satellite-2 (ICESat-2), Space.com reported, in the rocket’s 155th and final mission.

First entering service in 1989, the Delta II was NASA’s workhorse rocket, with Saturday’s launch capping off 100 successful launches in a row. (The last failure was in 1997, when a Delta II carrying a GPS satellite exploded seconds after leaving the pad.) As noted by the Verge, prior payloads have included the Spitzer and Kepler space telescopes, the Spirit and Opportunity Mars rovers, and the original ICESat.
