New Horizons’ first photos of Pluto’s smallest moons
May 14, 2015

For the first time, NASA’s New Horizons spacecraft has photographed Kerberos and Styx – the smallest and faintest of Pluto’s five known moons. New Horizons has been journeying toward Pluto since 2006 and will sweep closest to Pluto on July 14, 2015.

It was way back in July 2013 that New Horizons first saw Pluto’s large moon Charon. It began to see Pluto’s smaller moons Hydra and Nix in July 2014 and January 2015, respectively. New Horizons is now within sight of all the known members of the Pluto system. Will new moons be found? Stay tuned.

Drawing ever-closer to Pluto, New Horizons will begin its first search for new moons or rings in mid-May. Rings, in particular, might threaten the spacecraft on its passage through the Pluto system. The images of faint Styx and Kerberos shown here are allowing the search team to refine the techniques they will use to analyze those data, which will push the sensitivity limits even deeper.

Kerberos and Styx were discovered in 2011 and 2012, respectively, by New Horizons team members using the Hubble Space Telescope. Styx, circling Pluto every 20 days between the orbits of Charon and Nix, is likely just four to 13 miles (approximately seven to 21 kilometers) in diameter, and Kerberos, orbiting between Nix and Hydra with a 32-day period, is just six to 20 miles (approximately 10 to 30 kilometers) in diameter. Each is 20 to 30 times fainter than Nix and Hydra.

4. What a waste of money.

Whether it is space exploration, researching cures for disease, fixing deteriorating infrastructure, it is ALL a huge WASTE!

I know a family who could use this money, and I am NOT kidding.

Six siblings, they inherited a little bit but it is not enough and we need to divert funds from waste like this to them, PLEASE!

5. You totally got me, there. I was on the verge of retort.

Not hyper-funding NASA is one of the stupidest acts we've ever committed as a nation.

Really, really effing stupid.

6. That one really got me too. We have a house and Senate run by idiotic children.

If you talk to people who have been in DC for a long time, they will tell you that the teaparty person is a moron who has no clue of culture, no clue of government, etc. And they are not exaggerating, actual MORONS

That these elected officials are dumber than stumps, all of them

And mean, very mean

Either they need to do something extremely harmful so we can react and correct, or we must somehow resolve the stealing of dozens of elections every two years with illegal gerrymandering.
