Orion launched! Go go go!















Good booster separation. Everything is awesome...







First stage separation, service panel jet, abort-tower jet, all good!



Secondary Engine Cut Off. Perfect launch - no issues or anomalies, right on the numbers and everything on schedule! Orion will chill here for a while. In about an hour and a half, the second stage will ignite again for about 5 minutes or so, to send the spaceship out into deep space.



I'm going back to bed. I'll be back when it's getting close to landing time, a bit less than 4 hours from now.

Back!







So, Orion has flown out through the Van Allen belts and has come back through them safely. A short time ago it separated from its service module and will soon begin firing thrusters to orient itself for reentry.



Coming up on entry interface - the moment the spaceship makes contact with Earth's atmosphere. There may be a signal blackout as plasma builds up around the module while it comes in.



Here we go...!

Signal re-acquired. Trajectory on the nose.

Subsonic...

Chute deploy...!

SPLOOSH!!!!

Recovery vehicles' video has confirmed Orion is upright and it's little water-wing floats have deployed.

I saw some of this happening on tv, namely a recording of the launch and the live splashdown.
Amazingly flaw free... I think it was someone from NASA that was on MSNBC (Tamryn Halls show) who was practically flabbergasted at how perfect the entire mission went.

The last number I heard was that it was within 1 mile of the target.
Or maybe it was 1,000 feet?
I think it was feet.

Very cool stuff.

Did you notice in the video at about 5 mins in you can see the spacecraft's shadow against the clouds. That seemed shinny to me.

So - videos! I know you wants them.

Firstly, here's another video of the launch...from NASA's channel, which means no big annoying CLICK MY STUFF banners or ads, and also glorious high-definition! Also starts much close to the moment of liftoff:


Here's another nice close-up camera of the launch from one of the pad towers, also high-def:


Next, we've got NASA TV's stream of the decent and chute deployment:


And finally the moment of splashdown, taken from the recovery ship (YUMMY high-def!)


So full-screen that stuff and salivate!

Next up - NASA's New Horizons probe comes out of hibernation today, in a little over 9 hours. New Horizons was launched 8 years ago and is headed for the Kuiper Belt. Next year it is expected to rendezvous with the non-planet Pluto, which is why it is being brought out of hibernation now. It will not orbit Pluto, since Pluto is so small that it 1) isn't a planet and 2) doesn't really have enough gravity to capture a spacecraft traveling as fast as New Horizons. Rather, it will do a flyby, which will provide the closest-yet and most high-resolution photos ever taken of Pluto - which will be exciting! Then, New Horizons will continue on, being steered toward one of three candidate KB objects that were identified by the Hubble last year as being within New Horizons' ability to approach, and from there out to the outer heliosphere and the great who-knows.

Would now be a good time to say I've held something that's actually on New Horizons?

Previous job I made optical filters...one of our clients was NASA/JPL. We (not me specifically) made filters for the cameras on board.

Owner of the company got to go watch the launch....jerk

I also helped prototype filters that were on board India's mission earlier this year.

IT'S ALIIIIIVE!!!

The DSN is receiving telemetry from New Horizons!

Bear in mind it won't be a lot of dense chatter. The probe is so far away from Earth that radio transmissions take four and a half hours the bridge the distance.

Anyone still awake? Got clear skies outside? Go out and watch the Geminids! Nice meteor shower. Tonight it's cloudless and dark where I'm at, and I managed to see 1 or 2 a minute - some of them nice and strong too.

They'll be coming from the direction of the constellation Gemini (think left of Orion, on the other side of the Milky Way ribbon), but of course you can see them anywhere in the sky really. So just look up, don't focus on any one point, and wait. Pretty!

My kid and I went out for about an hour early on, saw a few from our vantage point (Hard to find good light pollution-free areas around here), and he went out about 2:30 am and saw about 20 in half an hour before the clouds finally rolled in.

It's usually cloudy for us on meteor shower nights...last night was the best in years!

THAT MAP THOUGH!
But seriously, that map is awesome.
I took a moment to check out the future ones and where'll there'll be and the likelihood on whether I'd be alive or not, lol.

Looks like the one in 2017 will be the best option really.
Which, if all goes to plan, means we'll be living in Washington state at the time, so we'll be able to drive down.
(Lil Kick will be 5 and hopefully he'll have a ~2 year old sibling by then.)

Just remind us when it gets closer, k?
Yes, I'm asking for a reminder almost 3 years from now.

Okay so, SpaceX launched another Dragon last night. The mission was to launch some cargo to the ISS, and meanwhile the first stage of the rocket once released was to pilot itself back to Earth, finding a floating landing pad in the ocean and landing softly and safely upon on it.

Well part one of the mission was successful; the cargo has reached the station, so no problems there, As for the second part... well, the good news is that it did find the ocean landing pad successfully, even in darkness and a bit of lower than optimal visibility which is laudable. Unfortunately, it didn't so much 'land' on it as... well let's just say it made a big impact.

Bummer about the landing, but really... it still found a floating landing pad in the ocean!
Sounds impressive to me.

And I'm no rocket scientist, but it seems like that should be an easier problem to fix than say... the entire thing blowing up or flying off to Las Vegas or Ibiza instead of the middle of the ocean.

The crew of the ISS has had to evacuate a section of it after an alarm warning of an ammonia leak earlier today. NASA now believes the alarm was caused by a faulty sensor, not an actual gas leak.

I wonder if the worms are ok...
(Since it sounds like it was just a faulty sensor, I'm guessing nothing was in danger in the first place. But it gave me a segue into this next story...




Nothing to squirm about: Space station worms help battle muscle, bone loss

Quote:
Two investigations on the space station help researchers seek clues to physiological problems found in astronauts by studying C. elegans -- a millimeter-long roundworm that is widely used as a model organism. This simple, tiny roundworm could lead to a cure for symptoms affecting millions of the aging and infirm population of Earth, and the astronauts orbiting it, potentially offering a solution to a major problem in an extremely small package, scientists say.

Dawn Delivers New Image of Ceres

Quote:
As NASA's Dawn spacecraft closes in on Ceres, new images show the dwarf planet at 27 pixels across, about three times better than the calibration images taken in early December. These are the first in a series of images that will be taken for navigation purposes during the approach to Ceres.
Over the next several weeks, Dawn will deliver increasingly better and better images of the dwarf planet, leading up to the spacecraft's capture into orbit around Ceres on March 6. The images will continue to improve as the spacecraft spirals closer to the surface during its 16-month study of the dwarf planet.

I never imagined, as a ten-year-old boy learning about the Solar system, that Ceres was anything more than a jagged, irregular chunk of rock. It's fascinating to see it as a spherical object.

Don't believe the light: Supernova in 'Einstein Cross' is a cosmic trick



Quote:
An exploding star goes supernova only once. But if you're really, really lucky, you might just get to see it happen four times.

An international team has discovered four separate images of the same distant supernova arranged in the shape of a cross — and this unusual trick of the light could help scientists test the structure of the cosmos. They reported their find in Friday's edition of the journal Science.

The formation of the four supernova images, in a shape known as an Einstein Cross, had been predicted half a century ago by Sjur Refsdal, a Norwegian astrophysicist who died in 2009. The new supernova is named SN Refsdal in his honor.
