New Space Toilets
NASA’s first new space potty in decades — a $23 million titanium toilet better suited for women — is getting a not-so-dry run at the International Space Station before eventually flying to the moon.

The second shuttle launch (STS-27) after the Challenger disaster almost ended in disaster.
One report describes the crew as “infuriated” that Mission Control seemed unconcerned. When Commander Gibson saw the damage he thought to himself, “We are going to die”, and did not believe that the shuttle would survive reentry; if instruments indicated that the shuttle was disintegrating, he planned to “tell mission control what I thought of their analysis” in the remaining seconds before his death.
The shuttle Atlantis actually sustained more damage than what would bring down Columbia in 2003. The Top Secret payload (a surveillance satellite for the US DOD) meant that communication with the ground was done using a slower method of encryption which could have resulted in lower quality images for analysis (eg. higher compression for faster transmission over a slow line).
Jupiter – New View

Bonus: The Moonraker (James Bond) score works great even if the obvious (and maybe overused) choice would have been Holst’s track.
Hubble finds 10 times as many galaxies as previously thought. NBD.
One of the most fundamental questions in astronomy is that of just how many galaxies the universe contains. The landmark Hubble Deep Field, taken in the mid-1990s, gave the first real insight into the universe’s galaxy population. Subsequent sensitive observations such as Hubble’s Ultra Deep Field revealed a myriad of faint galaxies. This led to an estimate that the observable universe contained about 200 billion galaxies.
The new research shows that this estimate is at least 10 times too low.
Juno.
NASA’s Juno spacecraft captured a unique time-lapse movie of the Galilean satellites in motion about Jupiter. The movie begins on June 12th with Juno 10 million miles from Jupiter, and ends on June 29th, 3 million miles distant. The innermost moon is volcanic Io; next in line is the ice-crusted ocean world Europa, followed by massive Ganymede, and finally, heavily cratered Callisto. Galileo observed these moons to change position with respect to Jupiter over the course of a few nights. From this observation he realized that the moons were orbiting mighty Jupiter, a truth that forever changed humanity’s understanding of our place in the cosmos. Earth was not the center of the Universe. For the first time in history, we look upon these moons as they orbit Jupiter and share in Galileo’s revelation. This is the motion of nature’s harmony.
Shock Breakout: Exploding Star
The brilliant flash of an exploding star’s shockwave—what astronomers call the “shock breakout” — is illustrated in this cartoon animation. The animation begins with a view of a red supergiant star that is 500 times bigger and 20,000 brighter than our sun. When the star’s internal furnace can no longer sustain nuclear fusion its core to collapses under gravity. A shockwave from the implosion rushes upward through the star’s
The audacious rescue plan that might have saved space shuttle Columbia
One of the most tragic events in the history of space exploration is the loss of the space shuttle Columbia and all seven of its crew on February 1, 2003—a tragedy made worse because it didn’t have to happen. But just as it is human nature to look to the future and wonder what might be, so too is it in our nature to look at the past and wonder, “what if?” Today, 13 years after the event, Ars is rerunning our detailed 2014 examination of the biggest Columbia “what if” of all—what if NASA had recognized the danger? Could NASA have done something to save the crew?
What we’ll do in space by 2016. Er…they
With such rapid expansion of capability, it may seem difficult to tell what the next 60 years will bring, much less the next century. But we never do anything in space without first imagining what we could do, so in that spirit, here is an attempt to predict—and nudge us into—the future.
