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. 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.

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.
A NASA satellite designed to precisely measure changes in Earth’s ice sheets, glaciers, sea ice and vegetation was launched into polar orbit from California early Saturday.

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?!
It didn’t begin as a big deal—and perhaps this is why mainstream news services are slow to pick up on the latest information. But now, in my opinion, it is a very big deal.
A small hole was discovered on a Russian Soyuz spacecraft (a lifeboat) attached to the International Space Station. That hole, about the size of a pea, resulted in the slow decompression of atmosphere. The air that our astronauts breathe was leaking out of ISS and into the void of space.
So far, the story is unremarkable. Ground scientists issued two comfort statements about the apparent accident. They addressed the possible cause and the potential risk:
The initial news event was interesting to space buffs, but it didn’t seem to present a significant threat to our astronauts, nor require a massive technical response. You may recall that duct tape played a critical role in getting the Apollo 13 astronauts safely back to Earth almost 50 years ago. The crisis that they faced was far worse. The solution required extensive impromptu engineering both in Houston and up in the spacecraft. What an awesome historical echo and footnote to an event that captured the hearts and minds of so many people back in 1970.
But the story does not end with a piece of duct tape. In fact, it just got much more interesting…
After a few days, NASA revealed that the hole was intentionally drilled, and the deed probably occurred while the ship was docked at the space station. Since there is no log of activity with tools in this section of the laboratory, it strongly suggests an act of sabotage by one of the astronauts on board.
And now, we have some new information: Guided by ground engineers, astronauts fished an endoscope through the hole to inspect the outside of the spacecraft. Guess what?! That same drill bit damaged the meteorite shield which stands 15 mm beyond the pressurized hull of the spacecraft. This will add significant risk to anyone traveling back to earth in the damaged ship.

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.
