Send Your Name to an Asteroid

Hey Space Placers!

   Want to go into space?

    Now you can, or at least your name can. JAXA has started collecting names to send to an asteroid which will be left on the space rock. You can also opt to have your name on the sample return capsule, or on both.

   Spacecraft planners are doing this on almost each solar system mission which is smart because it gets the public interested in the mission and allows us to be a part of it. My family's name is on just about every spacecraft that has done this.

Get the details here: http://www.jspec.jaxa.jp/e/hottopics/20130329.html#

Meteors and Saturn's Rings

Hey Space Placers!

    Here's something we have NEVER seen before - meteors in Saturn's rings!!!!

    For the first time ever NASA's Cassini spacecraft at Saturn has captured meteors in Saturn's rings - just unreal.
Meteors Meet Saturn's Rings

   Saturn now joins Earth, the Moon and Jupiter as places where impact events have been observed. Read More About It: http://www.jpl.nasa.gov/news/news.php?release=2013-147

   Speaking of the ringed planet, I'll have a blog ALERT on the 28th about Saturn's closest approach to Earth for the year.

   Have a GOOD weekend everyone.

More on Comet ISON

Hey Space Placers!

  To follow up from yesterday, check out NASA's video on HST photographing Comet ISON:

http://science.nasa.gov/science-news/science-at-nasa/2013/24apr_hubbleison/

   Comet ISON has been producing large amounts of dust even when it was out beyond Jupiter. At one point it was estimated that the comet was shedding 112,000 pounds of dust a MINUTE! I am sure that rate has gone up and will continue to do so as the comet comes ever closer to the Sun.

  As a result of that shedding and the effect of the Sun on the dust, it is expected that the Earth will pas through this dust in January 2014. Normally this would mean a meteor shower but the dust grains are so small they will not burn up in our atmosphere.

   Instead they will remain aloft for some time and perhaps produce some high altitude electric blue colored clouds called noctilucent clouds. These are amazing to see - I have never seen one - but hope that Comet ISON will give me my first view ever.

Hubble Photographs Comet ISON

Hey Space Placers!

   I knew it was only a matter of time until Hubble Space Telescope turned its attention to the potential "Comet of the Century" ISON. Wow oh wow, what a result:


Even at 394 MILLION miles from Earth and 386 million miles from the Sun this comet is a thing of beauty. The picture was taken April 10th and the blue hue was added to enhance details. The comet's nucleus, or solid central body, is estimated to be 2 to 3 miles across. Further analysis will be done as time goes on and distance decreases.

   It is remarkable that the comet already has a coma - the fuzzy area around the nucleus that is 3,100 miles across - a tail that extends for 57,000 miles, and a small jet on the upper right that is on the Sun facing side of the nucleus. This jet is blowing volatiles and dust off of the surface of the nucleus.

   Comet ISON is currently moving at 47,000 miles per hour and will increase its' speed as it gets closer to the Sun. The show is probably going to continue to improve as the comet gets closer to the Sun and exposed to greater heat. One can only imagine what will happen when this comet passes only 700,000 miles from the Sun! 

   I can hardly wait!!!!!

   Stay tuned as we countdown to Comet ISON. I will have more on the comet tomorrow.

Antares Lifts Off

Hey Space Placers!

Orbital's Antares rocket lifted off successfully today - 4/21/13 at 5 p.m. EDT:

Antares leaves the pad on its way to a successful orbit.

The second stage ignited right on time and the system delivered a test mass into orbit.

The successful test paves the way for further test flights launched from NASA's Wallops Launch Facility in Virginia and ultimately lead to rendezvous with the International Space Station (ISS).

Orbital is the second commercial company to launch a rocket designed to ultimately deliver cargo to ISS. SpaceX was first and has delivered cargo to ISS.

These companies mark the eventual return of American hardware delivering cargo and perhaps astronauts to ISS instead of relying on foreign capability.

This is a major landmark in America's space program and spurs competition and redundancy in this most critical area.

Solar System Genesis Meteorite Grains

Hey Space Placers!

   Current theory holds that the Sun and solar system were created when a nearby supernova shockwave began the collapse of our gas and dust nebula. As the proto-solar nebula continued to collapse the Sun eventually began nuclear fusion to become a star and the proto-planets became full fledged planets with asteroids and comets marking the original materials of our solar system.

NASA/JPL-CALTECH/ O. KRAUSE (STEWARD OBSERVATORY)
In 2007 NASA’s Spitzer space telescope found the infrared signature of silica (sand) in the supernova remnant Cassiopeia A. The light from this exploding star first reached Earth in the 1600s. The cyan dot just off center is all that remains of the star that exploded. 


 
























In our studies of meteorites, we have found grains within certain space rocks that were older than the solar system itself. The only way to explain this is to consider that grains of material from other stars must have been part of our original nebula. This makes perfect sense when we see the remnants of supernovas seeding space with the elements created while the star was alive and in its fearsome death throes.

These elements would seed other nebulas with all of the elements that are lighter and heavier than iron. That is why our planet has gold, silver, uranium and titanium for example, because they were made in a supernova explosion, propelled out into space and seeded our nebula. When the Earth formed over a long period of time all of the elements that were in the countless planetesimals (space rocks or asteroids) that collided with our ever growing planet became part of Earth.

Current studies of two meteorites have found a grain of silica (the main component of sand) in each that share the same chemical properties. The only way this could happen would be for these grains to have a common source - a nearby supernova event. The presence of silica is of great interest because it is thought to be formed just before a star dies as a supernova. The star tries to survive by burning whatever it can in a runaway fusion process which forms an onion skin layer of elements before the fatal core of iron shuts down fusion and the star collapses and explodes.

WIKIMEDIA COMMONS
A massive star that will explode at the end of its life, a core-collapse supernova has a layered structure rather like that of an onion.

With the unique chemical properties these silica grains had the scientists were able to model conditions that must have been present in the soon to be supernova star to form them. And for TWO meteorites to have these same unique chemical properties present in each, well, that is pretty amazing.

More meteorites will be examined to see if additional grains are found. Read More About It:

UPDATED Sky Guy Viewing ALERT Antares Launch 4-20 and Lyrid Meteor Shower 4-21 and 22

Hey Space Placers!

UPDATE: NASA is trying for launch of Antares today, 4-21-13 at 5 p.m. EDT...check the website below and my earlier blog this week on how to tune in and/or see the launch.

Sky Guy in VA
------------------------

With recent events we all need a night under a clear sky to enjoy the calm and quiet of the stars.

The launch of Antares is scheduled for today, 4-20-13 at 5 p.m. EDT. See my blog from earlier this week to get viewing details. NASA TV will carry the launch live starting at 4:30 p.m. EDT. Get updates here: http://www.nasa.gov/exploration/commercial/cargo/orbitalsciences-index.html

The Lyrid Meteor Shower is a good way to sit back, relax and enjoy some peace and quiet.

Sky and Telescope illustration


This is not a major shower like the summer's Perseids or winter's Geminids. The shower can produce 10-12 an hour under ideal conditions but the bright Moon will interfere with this year's showers. It is still worth getting out tonight and watching the sky.

Kepler Finds More Planets

Hey Space Placers!

NASA's planet hunting spacecraft, Kepler, has found more planets, to include the smallest planets to date to be found in the "habitable zone" (HZ). The HZ is the area of space around a star that the temperatures on the planet should be able to sustain liquid water - a known precursor for life as we know it.

Habitable Zone (62splash)


Habitable Zone (69splash)

At the press conference held yesterday, April 18th, mission scientists discussed the latest finds of Kepler which now pushes its total of discovered exoplanets to 122 with no end in sight. Kepler has identified 2,740 possible exoplanet candidates.

In the two new systems rocky planets were found in the HZ, and Kepler 69's star is very similar to our own Sun. 

It is not known if any of these planets in the HZ can support life.

It is only a matter of time until Kepler finds an Earth-like planet in the HZ. Then the speculation about life on another planet can begin in earnest.

Sky Guy Viewing ALERT 3-14-13 - Moon, Jupiter and More

Hey Space Placers!

Spring has sprung here in the DC area and tonight promises to be clear and beautiful. For North America and Europe tonight's skies in the west will be a treat as the crescent Moon (complete with Earthshine) will be near Jupiter and some open star clusters.

Twilight view of Moon, Jupiter, and Pleiades
Night by night this weekend, the waxing crescent Moon marches up past stars and bright Jupiter. Illustration is free for use anywhere if you include a link to SkyandTelescope.com.

(The scene is drawn for the middle of North America. In Europe, move each Moon symbol a quarter of the way toward the one for the previous date. In the Far East, move it halfway.)
This is a good photo opportunity as well so get out with your camera, use a tripod and take exposures 
at 400 to 800 ISO of several seconds in a dark sky that has a tinge of dusk left or wait until it is 
completely dark.
You can see the parade of winter stars in the south with Orion, and Sirius, the brightest star in the night 
sky. The star of spring, Arcturus, is over in the east and is the brightest star in that region of the sky.

Hey Space Placers!

UPDATE:

Here is the link to our segment this morning:




I will be on WTTG, Fox 5, tomorrow (4-9-13) to discuss news stories about NASA sending a robotic spacecraft to capture and move a 20 to 25 foot asteroid before the end of the decade.

I want to make it clear that NASA has NOT officially made any comment on these news stories but we may learn something this Wednesday when NASA's 2014 budget is released.

Such a mission would be a first in that humanity would be manipulating a large space object for the first time. The Orion Crew Module would visit the asteroid several years later and conduct an exploratory mission.

It would mark the first time humans have gone beyond Low Earth Orbit since December 1972 - the last Apollo mission to the Moon.

Green Pea Galaxies

Hey Space Placers!

   Green Pea Galaxies -  yes, that is what they are called - may hold the key to an important era in the development of the Universe.


These rare galaxies were found by the public in 2007 during an Internet based citizen scientist  project in which the public studies galaxy images to classify them. Well, the Green Peas defied classification and became a major find.

The 6 Green Pea Galaxies that were studied are located 1 to 6 billion light years away and may hold clues to the time when the Universe was transforming from being opaque to transparent.

More on NWA 7325

Hey Space Placers!

Here is a news release that I know you will enjoy. Many of you have been fascinated, as have I, with the green meteorite NWA 7325 - a possible space rock from Mercury. 

The odd ball space rock was the subject of discussion at the recent 44th Lunar and Planetary Science Conference. How the meteorite was found, purchased and sent to Washington University at St Louis for preliminary testing, is a great read. As is the scientific discussion about the green space rock.  

More testing needs to be done so answers can be found but I am sure that the origin of NWA 7325 will be found. Oh, and we find out why the rock is green

1st Results From Alpha Magnetic Spectrometer

Hey Space Placers!

Yesterday results from the $1.5 billion Alpha Magnetic Spectrometer (AMS) located aboard the International Space Station (ISS) were announced.

EVA-AMS.JPG.jpg


The AMS has been detecting incoming cosmic rays  for the past several years before they interact with the Earth's atmosphere. The results, stemming from the analysis of over 25 billion recorded events, detected over 400,000 positrons or anti-matter particles. This was the largest detection ever in space for anti-matter and has significant possibilities in the search for dark matter.

The AMS international team of over 600 scientists is hoping that additional research will be able to zero in on the origin of this anti-matter. The prime suspect is that dark matter interactions are creating the detected particles but more work has to be done to totally eliminate the possibility that the particles are coming from pulsars in our galaxy.

The team expressed high confidence that in the upcoming months they will be able to eliminate the pulsars as a source and be able to zero in on dark matter as the cause or origin. Doing so will go a long way in furthering our understanding of this unseen and unknown component that makes up 25% of the Universe.

Forming Galactic Spiral Arms- New Research

Hey Space Placers!

We live in a spiral galaxy called the Milky Way and can see many other spiral galaxies in the Universe. But how they form their spiral arms and how they last has been a significant question.

Image: spiral galaxy formation

New research which included supercomputing simulations has provided some interesting results and a cool video on YouTube.

Read the results here http://www.news.wisc.edu/21636 before tuning in to YouTube here https://www.youtube.com/watch?v=5sGKuoBnTn0

By the way, the summer constellations that feature views of our galaxy are visible in the hours before dawn. But their true magnificence will have to wait until the hot nights of summer when fireflies keep earthly company with August thunderstorms and the Milky Way sweeping through Sagittarius into the Sumer Triangle.
