What's Up? The Space Place

Hey Space Placers! Once again spacecraft are preparing to orbit my favorite place in the Universe - our Moon. NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission with its two spacecraft, is set for a major mission milestone - entering lunar orbit - this New Year's weekend. GRAIL A & B will enter lunar orbit on New Year's Eve and New Year's Day respectively, at  1:21 p.m. PST (4:21  p.m. EST) for GRAIL-A and 2:05 p.m. PST (5:05 p.m. EST)  for GRAIL-B.  From NASA's Press Release yesterday:  As of Dec. 28, GRAIL-A is 65,860 miles (106,000 kilometers) from the  Moon and closing at a speed of 745 miles per hour (1,200 kilometers  per hour). GRAIL-B is 79,540 miles (128,000 kilometers) from the Moon  and closing at a speed of 763 mph (1,228 kilometers per hour). During their final approaches to the Moon, both orbiters move toward  it from the south, flying nearly directly over the lunar south pole.  The lunar orbit inse...

Hey Space Placers! I was at work yesterday and the subject of other life in the Universe made the rounds. To a person (there were 5) each thought that life other than us and our planet existed elsewhere in the Universe. I watched "Earth vs the Flying Saucers" last night and got the January 2012 issue of Sky and Telescope Magazine with the cover story "How Could Aliens Find Us?". To top it off, there is now a project being proposed to look for alien artifacts/evidence in the high-resolution photographs from Lunar Reconnaissance Orbiter (LRO) -  http://www.sciencedirect.com/science/article/pii/S0094576511003249 . I will state my own view on the subject of extraterrestrial life - I believe that other life DOES exist in the Universe, if not our own solar system. To create life - as we know it - you need a stable and long term energy supply, a suitable habitat (water, atmosphere, chemical compounds, food sources) and sufficient time for evolutionary processes to wo...

Hey Space Placers,    Took these pics last night (12-26-11) before the clouds rolled in. I hope you like them. Sky Guy in VA

Hey Space Placers! Tonight, December 26, 2011, the thin crescent Moon and brilliant Venus will pair together in the western sky right after sunset. This is a must see event as the two will be very bright and beautiful. The Moon will have earthshine - which is the unlit portion of the Moon being visible due to the reflection of sunlight off our planet's clouds and oceans. If you have binoculars it will be well worth using them to look at the Moon as you will see the main craters and rays. Start looking at about 4:30 to 5:00 p.m. in the southwest. As long as you have a clear western horizon free of trees and buildings the view will be beautiful and serene. Don't miss this celestial treat.

Hey Space Placers! While we prepare to enjoy the holiday season, NASA's Cassini spacecraft (and others) are working around the solar system. From the Sun to the boundary of the solar system itself, NASA's space explorers are sending us data and images. Cassini has a marvelous group of photos from Saturn and it rings and moons.

Hey Space Placers! Here is a link to an AMAZING video of Comet Lovejoy taken from the International Space Station (ISS) that you have to see:  http://www.nasa.gov/multimedia/videogallery/index.html?media_id=125774121 . The lightning in the South Pacific is the foreground for the comet's amazing tail rising out of the planet's atmosphere. Unreal! Sky Guy in VA

Hey Space Placers! Today is the 1st day of astronomical winter as the winter solstice occurred at 1230 a.m. EST, 12-22-11. The Sun will now begin to rise a little higher in our sky at local noon and move along the eastern horizon towards the North each day. Here in Northern VA our temp will be in the 60's(!) today, and we have had a few days of these temps off and on for the past week. The nights will remain long during winter so take advantage of seeing the stars and planets - Venus is in the southwest right after sunset blazing away and Jupiter is king high in the southeast. The winter constellations are rising in the east so be sure to look for Orion, Canis Major, Canis Minor, Taurus and Auriga. If you have clear skies tomorrow before sunrise, at about 6:15 to 6:30 a.m., be sure to go out and look in the east. I saw Mercury today through some clouds and it was bright and a fist or two width above the eastern horizon. It was bright and golden-yellow in color. It is brighter...

Hey SPace Placers! Yesterday it was plants made of diamond and today we have eco-planets found that are the size of our own Earth. NASA announced yesterday at a news conference that the planet hunting Kepler spacecraft had found a planetary system consisting of 5 planets orbiting a star about a 1,000 light years away. The Earth-sized planets, Kepler 20e and 20f,  are too close to their star to support liquid water so the prospects of life as we know it is unlikely. The temps on 20f are 800 degrees - like Mercury - and 1,400 degrees on 20e - hot enough to melt glass! Kepler's search will go on but this is a major milestone to finding an Earth-sized eco-planet in a habitable zone around a star.

Hey Space Placers! We know that there are plenty of planets besides our own solar system. In fact, NASA is going to hold a news conference today, Dec. 20, to announce the latest finds from Kepler - the planet hunting spacecraft. A recent experiment here on Earth developed the notion that planets somewhat similar in size to Earth could form being comprised of 50% diamond. Researchers were experimenting with what it takes to form diamond in the lower mantle of our planet. According to the news release from Ohio State University, " “Our results are striking, in that they suggest carbon-rich planets can form with a core and a mantle, just as Earth did,” Panero added. “However, the cores would likely be very carbon-rich – much like steel – and the mantle would also be dominated by carbon, much in the form of diamond.” Such a planet would probably have very cold and difficult conditions for life to form. This is another intriguing example of the planetary possibilities that may ...

Hey Space Placers! NASA's Dawn spacecraft completed its higher altitude mapping and has been lowered to about 130 miles. This will provide higher resolution photos and greater details on areas that were mapped at the higher altitude. The lower altitude will also allow for mapping of the gravitational field of the 2nd largest asteroid in the solar system which then allows for a greater understanding of the internal structure of the mini-world. The maneuver was done successfully on December 12 and Dawn will remain at this altitude for the next 10 weeks. She will then dive back up to the higher altitude of 420 miles to resume mapping of the northern regions with a more favorable Sun alignment. Dawn will head for the largest asteroid Ceres in July 2012. Read More ABout it:  http://www.jpl.nasa.gov/news/news.cfm?release=2011-384 Sky Guy in VA

Hey Space Placers! Meteorites - space rocks - are pieces of the Moon, Mars, perhaps Mercury, and asteroids that fall to Earth and are found. They contain priceless information about not only the history of the body they came from but that of the solar system as well. Each meteorite found and collected adds to our knowledge of the solar system, and in very rare instances, provides a history that PREDATES our Sun. Contained in some studied meteorites are what scientists call "pre-solar grains" - tiny bits of matter that were formed in a star other than our Sun. This star went supernova at some point creating elements beyond iron which were then dispersed into space. Some of this supernova's remnant material seeded the nebula of gas and dust that eventually formed our Sun, the planets, and the whole solar system. Pre-solar grain A scientist is going to search for such pre-solar system grains in a famous meteorite and has been awarded $1.38 million to do so for the ...

Hey Space Placers! Well, I have to tell you that the Comet Lovejoy experience of the past few days has been one of the most memorable for me in my five decades of astronomy. The reason I say this is because of two things - the very nature of the event and its' very unexpected outcome and the state of astronomical instrumentation that allowed all of us to to view astronomical history in the making in almost real time. I put this event on the same plane as the Comet Shoemaker-Levy 9 impact of Jupiter. That event showed us for the first time in history an actual cometary impact with a solar system body. For those of you not familiar with this event check it out:  http://www2.jpl.nasa.gov/sl9/ . It changed the way we see the solar system since we were able to witness and study a very important process in the life of the solar system - impacts. Comet Lovejoy defied the experts' predictions (and mine too) that it would not survive its close encounter with the Sun but it did. To...

Hey Space Placers! You have got to see the movies that show Comet Lovejoy, the kamikaze comet, diving into and out of the Sun! The comet became very bright with a long curving tail going in and then you can see the remnant without a tail going out. Simply amazing. I have to tell you I am glad this ancient piece of the solar system survived. It is going to give us information on comet structure and characteristics we would not have obtained otherwise. I am sure there will be some papers published in the future about this most unique episode in sungrazing comet history. Here are the links to the movies:   http://spaceweather.com/images2011/16dec11/phoenix_comet_emerges.mov?PHPSESSID=3puch6tnfd9ru4t6ifc7mhinh3   (truly amazing to see the remnant coming around the Sun!) and http://spaceweather.com/images2011/16dec11/lovejoy_c3_anim.gif . Now Comet Lovejoy, or what is left of it, will recede back into the solar system, and become part of astronomical history. I have not s...

Hey Space Placers! Comet Lovejoy may be in the final hours of its existence today as it will be closest to the Sun at 7pm EST today. Here is the link to see the latest SOHO pictures:  http://sohowww.nascom.nasa.gov/data/realtime-images.html . The main view will be in the lower right corner -  LASCO C3 - so make sure you check on Comet Lovejoy as the day progresses. Will it survive? Probably not. What will be the end result of its destruction? No one knows for sure - it may become very bright and then disintegrate into a large cloud or it may go quietly with nothing to mark its passing. Only time, gravity and the Sun's intense heat will tell. Sky Guy in VA

Hey Space Placers! The Dawn spacecraft has been studying Vesta since its arrival months ago and the scientific results are adding up to the following question, "Is Vesta the smallest terrestrial planet?" In other words, is Vesta a failed planet that would have been similar to the terrestrial planets of Mercury, Venus, Earth and Mars. Vesta has characteristics that qualify it for such a designation - iron core, complex geological history. But such a designation has to come from the International Astronomical Union (IAU) - the worldwide congress of professional astronomers who vote and decide on such things. IAU demoted Pluto from planetary status and could do the same for Vesta by promoting it from asteroid to dwarf planet status. Only time and more data will tell.

Hey Space Placers! I hope you are tuning in to SLOOH - see yesterday's blog for the link - to watch the lunar eclipse live. NASA's Lunar Reconnaissance Orbiter (LRO) is working during the eclipse to gather valuable data on how the Moon cools down during totality. On the Moon you would see a total SOLAR eclipse as the Earth blocks out the Sun. When this happens the temperature on the Moon's surface begins to fall. By how much and how fast this temperature declines and then rises once the Sun returns, yields valuable information abut the surface composition and texture of the area measured. LRO carries DIVINER, an instrument designed to take the Moon's temperature. DIVINER will take thousands of measurements during the eclipse which really is a scientific windfall of valuable data that could not be obtained otherwise. So enjoy the eclipse and wish LRO a successful workday. Read More About It:  http://www.nasa.gov/mission_pages/LRO/news/dec2011-eclipse.html Sky G...

Hey Space Placers! Our Moon continues to surprise us the more we study and explore our nearest neighbor. I have three news items as another story broke yesterday. From NASA, "The science team that oversees the imaging system on board NASA’s  Lunar Reconnaissance Orbiter (LRO) has released the highest resolution near-global topographic map of the Moon ever created. This new topographic map, from Arizona State University in Tempe,  shows the surface shape and features over nearly the entire Moon with  a pixel scale close to 100 meters (328 feet).

Hey Space Placers! NASA's Cassini spacecraft has been diligently monitoring the large storm on Saturn for nearly a year. As described by NASA, " These brand new, full-color mosaics and animated movies begin with the storm's emergence as a tiny spot in a single image on Dec. 5, 2010, and follow its subsequent growth to a storm so large it completely encircled the planet by late January 2011. The disturbance, which extends north-south approximately 9,000 miles, or 15,000 kilometers, grew to be the largest observed on Saturn in the past 21 years, and the largest by far ever observed on the planet from an interplanetary spacecraft. Other instruments on Cassini have detected the storm's electrical activity and revealed it to be a convective thunderstorm. Its active convecting phase ended in late June, but the turbulent clouds it created linger in the atmosphere today."

Hey Space Placers! Today is an important day for the future of the International Space Station (ISS) as the Russians are preparing to launch the next trio of few crew members to the ISS at 11:14 today, Sunday Nov. 13, 2011. This is crucial as the Soyuz launch vehicle that lofts the crew to orbit is the same type that failed August 24th and grounded the Russians as they figured out what went wrong. Since the U.S. retired the Space Shuttle, the Russians are the only ticket to the ISS. If there is another problem with the Soyuz, it can have very dire circumstances for the future of the $100 billion ISS. It is also disconcerting that that the Russians suffered another engine malfunction with their recently launched Mars mission to Phobos.

Hey Space Placers! The Earth should be in one piece by tomorrow night (Nov 8). If it isn't, at least it won't have been caused by the passage of an aircraft carrier sized asteroid named 2005 YU 55    We know 100% for sure that the Earth will not be hit by this rock for 100 years. It has a close encounter with Venus in 2029 that will alter its orbit so we will have to monitor its new orbit. This nomad of the solar system comes closest to us on November 8th at 6:28 p.m. EST, when it passes 198,000 miles (319,000 km) from Earth's surface. By the way, that is well inside the Moon's orbit which is about 240,000 miles on any given day. This space rock is remarkably spherical and will be close enough that we will be able to get radar returns and further our knowledge. Amateur and professional astronomers are planning observing runs to capture images and associated data as the asteroid makes its closest approach to learn even more about this interloper.

Hey Space Placers! Nov. 25th is the projected launch date of NASA's newest mission to Mars. The Mars Science Laboratory, named Curiosity, is due to land in a crater named Gale - a 96 mile wide crater that has a central mountain that is three times higher than the Grand Canyon is deep. Gale Crater was selected for the landing site as it is thought to be a place where the past history of Mars will be available in the layers of sedimentary rock that abounds in the crater. By studying these layers with the sophisticated instruments on board Curiosity, and its ability to roam the Martian surface, scientists are very optimistic that a treasure trove of information will be discovered. SO when you watch Mars get brighter in the sky in the upcoming weeks think about Gale Crater and what we will find there - perhaps building blocks of life if not not proof of life itself.

Venus is low in the southwest just as it begins to get dark - if your horizon is clear you cannot miss the brilliant greenish-white planet. Venus will continue to get higher and brighter in the sky as the weeks go by. With the return to standard time tonight, we will have even more darkness hours to enjoy the night sky as we progress to the Winter Solstice in December. So as darkness falls, Venus is in the southwest, Jupiter in the east with the Moon. Mars is in the predawn hours keeping bright Regulus company. Enjoy the sky....don't forget to check out the fly overs of the International SPace STation - get the updates for your location at http://spaceflight.nasa.gov/realdata/sightings/. Sky Guy in VA

Hey Space Placers! You have to check out the BIG sunspot that is causing a bit of a stir as it is one of  the largest we have seen on the Sun in awhile.This sunspot has been active producing solar activity and will probably continue to do so. See more about this sunspot here: http://www.spaceweather.com/archive.php?view=1&day=04&month=11&year=2011  and follow its progress from day to day. Sky Guy in VA

Hey Space Placers! The Universe is ALWAYS full of surprises and here is the latest - a star that has spiral arms! Located in Lupus the Wolf at about 400 light years, this star may be in the process of creating new planets.

Hey SPace Placers! For you early risers - an hour or more before dawn, be sure to look up Mars high overhead, a little towards the east. Mars is becoming brighter as it moves closer to Earth and it now is a little brighter than the star Regulus in the constellation of Leo the Lion. You will see Mars and Regulus near one another and Mars is steadier, brighter and reddish-orange tinted as opposed to yellowish-white Regulus. Mars will continue to get brighter and redder in color as the weeks roll by. It is fitting that we know where Mars is in the sky as NASA prepares to launch Curiosity towards the Red Planet on the 8th of this month. The super rover-laboratory on wheels promises to revolutionize our search for signs of life - past and present- on the planet in Gale Crater. More to come on Mars and Curiosity to come but take a peek tomorrow in the pre-dawn sky and spot the Red Planet for yourself.

Hey SPace Placers! Well, the trick or treaters will be out in force tonight as Halloween is upon us - hard to believe that November is here already. In the DC area we will probably be clouded out but for the rest of you that enjoy clear skies tonight be sure to check out the Moon in the south, Jupiter in the east and the summer triangle directly overhead. Russia recently launched its supply rocket to the ISS successfully so the logistics chain is back in place (if the supply ship docks OK). NASA is getting ready to launch the newest Mars mission - Curiosity - this week. I will have more on that as we get closer to the launch window. NASA is doing the final touched on the spacecraft and launcher this week at Kennedy Space Center. Have a safe and candy successful night! Sky Guy in VA

Hey Space Placers! Well, after our snowfall here in the DC/VA/MD area as well as a Nor'easter of historic significance in terms of it occurring in October, the sky is calling. Jupiter is now up all night, being visible in the east right at sunset and blazing brightly until sunrise. If you have binoculars you can see the four main moons and even the smallest telescope will show you the planet,  cloud bands and the moons in greater detail. Add to that the 1st quarter Moon on the 2nd and you have a sky watchers' treat. For those of you in the DC area come join us at GMU Observatory on Halloween. Jupiter and the Moon will provide a real "trick and treat" for those who show up. Check the website for further details:  http://physics.gmu.edu/~hgeller/observing.html Sky Guy in VA

Hey Space Placers! Here is everything you ever wanted to know about the Sun and its cycle. Be sure to check out the video. http://www.nasa.gov/mission_pages/sunearth/news/solarcycle-primer.html Sky Guy in VA

Hey Space Placers! If you have clear skies and a clear western horizon, make sure you look for the heavenly trio in the west right after sunset. Binoculars will help your search. The Moon will get higher in the western sky over the next few days and Venus and Mercury will remain close to one another. A great view if you can see it!

Hey Space Placers! If you are interested in impact events, you have to read the latest from Princeton University. The research has developed a better model for studying the effects of large impact events on Earth. I highly recommend reading the following: http://www.princeton.edu/main/news/archive/S31/90/32S94/ Sky Guy in VA

Hey Space Placers! Mercury continues to surprise and confound scientists as a result of the ongoing NASA MESSENGER mission. The latest revelation involves newly discovered features called "Sleepy Hollows" - pretty scientific sounding term I must say. According to NASA, "A key clue is that many of the hollows are associated with central mounds or mountains inside Mercury's impact craters. These so-called “peak rings” are thought to be made of material forced up from the depths by the impact that formed the crater. Excavated material could be unstable when it finds itself suddenly exposed at Mercury's surface."
