Lunokhod and the Dead Russian Spy

There's a big brouhaha right now in Great Britain regarding the mysterious death of a former Russian spy, who was discovered to have been poisoned with polonium-210. Interestingly, polonium-210, which is highly radioactive, was used by the Russian space program in the 1970s - primarily to power the Lunokhod rover that went to the moon. According to this article, a half-gram of polonium can generate 140 watts of energy by just decaying.

Arecibo Gone in 2011?

The New York Times has reported that the Arecibo radio telescope may be closed down in 2011 due to financial issues unless other sources of funding be obtained by the National Science Foundation. The Big Ear, as the radio telescope is known, is the most powerful radio telescope in the world, and is used by, among others, the SETI@Home project. Current astronomy projects being done in the facility may also be curtailed as Arecibo's budget may also be cut by 25% in the next three years.

MGS Phone Home

The Mars Global Surveyor is still out of contact. The spacecraft, launched 10 years ago to map the Martian surface using high-resolution cameras, has been out of touch from its controllers at the Jet Propulsion Laboratory more a week now, and NASA engineers and scientists are trying to re-establish contact with it. The MGS is currently in "safe mode" after it encountered a problem with its solar cell array.

Darth Vader Claims Space

George W. Bush recently signed a document that effectively extends Pax Americana to outer space. The document, called National Space Policy, underlines the strategic importance of having access to space. It stated that the national security of the US "is critically dependent upon space capabilities, and this dependence will grow." Hence, the US will "preserve its rights, capabilities, and freedom of action in space... and deny, if necessary, adversaries the use of space capabilities hostile to US national interests."

Klingons, you have been warned.

Heaviest Element Created

It seems periodic tables need to be reprinted again.
Researchers from the Lawrence Livermore National Laboratory have created a new element.

Element 118 is touted to be the heaviest, yet a short-lived one, element created so far. The researchers were able to achieve the feat by using a cyclotron to bombard californium-249 with calcium ions. The three atoms created by the scientists lasted for less than 1/1000th of a second though.
The new element has 118 protons and 179 neutrons in its nucleus, and has an atomic weight of 297.

Virgin Galactic's SpaceShip Two Unveiled

Take a peek at Virgin Galactic's SpaceShip Two, which will begin commercial space flights in 2009.

Armstrong was Grammatically Correct After All

Grumpy grammarians can get off Neil Armstrong's back at last. A computer programmer who studied the audio recordings of the first moon landing and found that Armstrong did say the oft-quoted words - one small step for a man, one giant step for mankind - correctly. It was previously thought that Armstrong omitted the "a," earning him the ire of anal grammarians everywhere.

Spacewoman's Blog

It seems that blogging has already reached outer space. If you're interested to read the thoughts of Anousheh Ansari, the first Muslim woman in space, while she was galivanting in the International Space Station, you can read her blog here.

A Planet That Floats on Water

Astronomers have discovered a new class of huge planets but has a density lower than that of water. The newly discovered body was detected orbiting a binary star 450 light-years away at constellation Lacerta. According to the discoverers, the planet, designated HAT-P-1, has the same density as cork, but is bigger than Jupiter, and if there's a big enough tub, it will float in water.

Xena Renamed

The International Astronomical Union has renamed Xena, the minor planet that was the bane of Pluto's existence. Xena, designated 2003 UB313, is now officially known as Eris, after the Greek goddess for discord. Its moon, previously dubbed Gabrielle, was named Dynomia, after Eris's daughter.

Asteroid 134340

Asteroid 134340 is now the official designation of Pluto, underscoring its downgrade to minor planet status. The new designation was given by the Minor Planet Center. Because they are part of the Pluto system, the companion bodies Charon, Nix and Hydra will also be called 134340 I, II and III, respectively.

The center also designated numbers to newly discovered bodies Xena (Asteroid 136199), and Kuiper Belt Objects 2006 EL61 (Asteroid 136108) and KBO 2005 FY9 (Asteroid 136472).

They should have seen it coming...

It seems that the controversy regarding the demotion of Pluto has repercussions far more than the IAU had expected. Astrologers from all over had been calling foul over the astronomy body's decision to demote Pluto from its planet status.

Astrologers are specially concerned about the demotion's effects on people whose zodiac sign is Scorpio (like me, for instance) as Pluto has an affinity with the birth sign. Most decided to stick with Pluto. Other astrologers are also in the bind whether to include the minor planets into the astrology charts that they consult when making horoscopes. One was a bit pragmatic though, saying "UB313 is never going to tell you whether Wednesday is good for romance," as the minor planet is so far away in the Solar System.

Well said. But then again, they should have predicted this already.

Thanks for the tip on the story, Bamm.

Europe lands on Moon with a bang

SMART-1, Europe's first mission on the moon, has landed with a bang. Literally. The spacecraft, which was designed to crash on the moon's surface, did so at a planned 1.25 miles/hour. The resulting dust cloud of the explosion was observed by scientists, who hoped that the dusts will give a clue on the composition of the area around the impact site.

SMART-1 was launched last September 2003 from the French space facility in Kourou. It uses an solar-cell-powered ion engine for propulsion.

More about SMART-1 here.

Pluto Demoted

The votation made by the delegates of the International Astronomical Union in Prague did not bode well for Pluto - the controversial body demoted from its planet status to a "dwarf planet." The new designation leaves the solar system with eight planets and four dwarf planets: Pluto, Ceres, previously designated an asteroid, Charon (previously Pluto's moon) and 2003 UB313, also known as Xena. The three will also be known as trans-Neptunian objects.

Dark Matter Confirmed

NASA scientists using data from the Chandra-X space telescope has confirmed the existence of dark matter. The little-known dark matter - deemed to composed 80-90% of all the matter in the Universe - was observed when two giant gas clouds collided, an event observed by Chandra-X, the Hubble Space Telescope, the Very Large Telescope and the Magellan Telescope. This is the first direct evidence that the the-theoretical dark matter is not just a stuff of theoretical astrophysics.

Solar System Gains 3 More Planets

An executive committee formed by the International Astronomical Union has approved a new definition of what a planet is, and by the new definition, the Solar System will have 12 planets, up from the present nine. Three bodies will be upgraded to the planet status: Charon, Ceres (formerly an asteroid), and Xena. The decision of the executive panel will be put on vote on August 24 by the delegates composing the IAU.

The new definition of a planet is: an object that circles the Sun, large enough to have gravitational forces that will compress it into a spherical shape, and at is least 250-500 miles in diameter.

The committee also came up with a new designation, called plutons, that encompasses planets that take at least 200 years to orbit the Sun. Plutons include Pluto, Charon and Xena. Ceres would just be an ordinary planet under the new definition, while Pluto and Charon, which orbit close to one another, will be a double planet system.

Many other objects might be upgraded to planet status, including Kuiper Belt Objects such as Sedna, Orcus and Quaoar, as well as asteroids such as Vespa, Pallas and Hygeia.

Quo Vadis, Pluto?

Members of the International Astronomical Union are gathering in Prague to discuss the fate of Pluto - whether to still consider the body as a planet or to demote it into a lesser status: asteroid, Kuiper Belt object, planetissimal. More importantly the outcome of IAU's discussio would be to define, for once and for all, what really a planet is. The group will also discuss the classification of newly discovered bodies like Xena and Segna. (And we think taxonomists had it easy classifying the platypus...)

My stance for the manner is that the IAU can set Pluto as the mininum size for a planet. This way Pluto's historical significance can still be preserved and saving us the trouble of updating all the books about the Solar System.

Carbon-based molecules found in space

It was reported that researchers using data gathered by the Robert C. Byrd Green Bank Telescope found eight types of complex carbon-based molecules in interstellar space. The molecules include acetamide, cyclopropenone, propenal, propanal and ketenimine, found in Sagittarius B2, and methyl-cyano-diacetylene, methyl-triacetylene and cyanoallene, found in the Taurus Molecular Cloud (TMC-1).

Sagittarius B2 is in the center of the Milky Way galaxy, around 26,000 ly from earth, while the TMC-1 is about 450 ly from Sagittarius B2.

This day in Astronomy: August 6

Ten years ago, NASA biochemist David McKay presented a Martian meteorite, named ALH84001, found to contain microscopic structures scientists surmise to be biological in origin. These structures are called polycyclic aromatic hydrocarbons, commonly produced by biological processes - the main argument used by McKay in his thesis that life could have existed in Mars, but many scientists have argued that PAHs can also be produced by non-biological means.

Moon as DNA Vault

The International Herald Tribune has recently run a story about the Alliance to Rescue Civilization, which advocates turning the Earth's satellite into a repository of DNA from all of earth's creatures, as well as a "compendium of all knowledge" . The vault and its contents, according to the group, will act as an insurance from catastrophic events, such as a major world war or an asteroid collission, that could wipe out civilizations.

SETI Coverup?

The Register is reporting the controversy regarding the alleged cover-up committed by the SETI Institute on the detection of alien signals from space. According to the report, SETI watcher Steven Greer accused the SETI Institute of covering up the the detection of signals that he believes to be part of an alien transmission. Greer also alleges that an organization also stepped in to block the said signals.

Sounds like Mulder and Scully are back again.

Stardust@home to go online August 1

Stardust@home, a new distributed computing project designed to look for microscopic interstellar dust grains collected by the Stardust mission, is set to go online on August 1. The program will use web-based virtual microscope programs to look for the tiny dust grains collected by the Stardust Interstellar Dust Collector. Around 50 dust grains are expected to be found from the tiles of aerogel used to collect the dusts. The Stardust spacecraft gathered samples near the comet Wild 2.

If you want to volunteer your computer time for the project, go here. The project is a joint effort between the Planetary Society and University of California at Berkeley.

ET Phones Home

I had a change of heart and decided to once again to participate in the SETI@home project. I now participate in three grid computing projects: Einstein@home, which aims to search for pulsars using data from the LIGO and GEO facilities, Rosetta@home, which investigates protein folding, and SETI@home, which looks for signals from little green men. SETI@home analyzes signals recorded by the Arcecibo radio telescope.

As of this moment, I have done 1,553 work units for Einstein@home and 149 work units for Rosetta@home, for a world ranking of 415,948th. I'm also ranked 189th for all participants from the Philippines.

Japan has fastest supercomputer?

It seems that Japan is again poised to take over the numero uno position in the supercomputing list once again. It was reported here that the MDGrape-3 supercomputer of RIKEN in Yokohama, managed to achieve a speed of one quadrillion floating-point operations per second - the first to reach petaFLOP speed. It is about three times faster than the current champ, the IBM-built Blue Gene/L. Blue Gene/L deposed the previous record holder from Japan, the Earth Simulator.

Supercomputers have applications in astrophysics, cryptography, nuclear physics and climate simulation, among others. For the comprehensive list of top supercomuters, go here.

Is SETI Worth It?

The Wall Street Journal ran an article last week about how SETI@Home has been an exercise of futility. SETI@Home is the online grid computing project that harvests idle CPU cycles from thousands of volunteers around the world and uses the computing power to search for that elusive "WOW" signal from aliens.

According to the author, Lee Gomes, SETI@Home has crowded out other grid computing projects that are more feasible and useful to humanity, projects such as Climate Prediction and Protein Folding Project that aims to find cures for diseases such as HIV and cancer.

There have been plenty of debate regarding Gomes' article. For me, I am now volunteering my CPU cycles to the Einstein@Home project - I think that illustrates fairly my views on the matter. While I won't discourage anyone from joining SETI@Home - as I also see it as a notable scientific exercise - I'd say that there are also plenty of other worthwhile projects around waiting for your idle CPU cycles.

Rocket Failure Cause by $5 Nut

This one could be funny if it weren't so tragic - yet another case of careless engineering? DARPA has announced that the cause of the March 24 crash of Falcon 1 rocket was a busted aluminum nut that cost only $5.

Falcon 1 was a rocket built by private company called Space Exploration (SpaceX). The rocket blew up shortly after launch due to a fuel leak caused by a corroded nut.

SpaceX plans to launch another Falcon 1 rocket in November.

Wishlist: Astronomer's Versatool

I saw this while browsing on the Net, a sort of Swiss knife for astronomers - the Astronomers Versatool. It's a multifunction tool with 21 attachments useful for a night out with the stars, including an optics brush, hex keys for collimation, a red LED flashlight, wrenches and even a pen. It's priced something like $25.

Discovery is back

The Space Shuttle Discovery landed safety at the Kennedy Space Center after a 13-day mission. The shuttle, with a complement of six crews, carried supplies to the International Space Station and perform some maintenance and experiments during the mission.

After the successful mission NASA scheduled 16 shuttle flights up to 2010, of which the shuttles will then be retired. The next shuttle flight will be on August 28, this time with Atlantis. Discovery will also fly again in December.

St. Ignatius Stargazing

This is a painting of a Jesuit friend of mine, Fr. Jason Dy. Entitled Inigo, nakahangad sa mga bitoon, ug namalandong (I├▒igo, stargazing and meditating), it depicts St. Ignatius looking at the stars. Aside from its religious undertones, I think the painting should be a fitting tribute to the Jesuit penchant for astronomy. It was the Society of Jesus which founded the Manila Observatory in 1865 in the Philippines, which became the forerunner of the Weather Bureau and later the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA).

China's Moon Probe will broadcast music

China announced that its lunar orbiter, Chang'e, will broadcast Chinese music while it is orbiting the moon. The spacecraft, planned for 2007 launch, will take 3D pictures of the lunar surface and analyze the lunar soil. The $170-million probe will also broadcast music - ranging from Chinese folk songs to Hong Kong pop - to increase public awareness to the Sino space program.

The lunar craft was named after the legendary Chinese goddess who flew to the moon.

Is Pluto a Planet?

There was an ongoing discussion on the UP Astronomical Society e-group about the upcoming vote on the classification of Pluto as a planet by the International Astronomical Union. Apparently, according to Bamm, one of the members, the Philippine representative to the IAU, Dr. Cynthia Celebre, has been consulting the local astro community regarding the issue. IAU will vote on the issue in August, and the Philippines will have a vote in the General Assembly.

The problem with this issue is that there is no clear definition of what a planet is . Originally planets include the seven bodies visible to the naked eye, including the moon. The standard definition now is: a planet is an accreted body orbiting a star (and small enough to not trigger a thermonuclear fusion reaction on itself), but almost all of the bodies orbiting the sun could fall into this definition. For a long time now the designation of a planet has been somewhat arbitrary.

For me what Dr. Celebre should consider and ask the Filipino astro community is: What should be the scientific definition of a planet. If the IAU can settle this (as it promised to release a ruling on this one in September), then the issue on Pluto (and the classification of all other subsequent bodies discovered or to be discovered in the future, like Sedna and Xena) will be settled as well.

Asteroid Flyby on July 3

The asteroid 2004 XP14 is expected to approach Earth on July 3. Though not exactly a doomsday scenario, the half-mile diameter rock will flyby at a distance of roughly 268 thousand miles, a hairpin in astronomical terms.

The Apollo-class asteroid (which means it has an Earth-crossing orbit), was discovered on December 10, 2004, and is classified as a Potentially Hazardous Asteroid. It will be closest to the earth at 4:25 UT on Monday.

semimajor axis = 1.032 AU
eccentricity = 0.162
inclination = 32.5°
perihelion = 0.865 AU

Meet Nix and Hydra

Newly Discovered Moons of Pluto Named

The International Astronomical Union named the two newly discovered moons of Pluto - Nix and Hydra. The moons, spotted by the Hubble Space Telescope and discovered by astronomers led by Alan Stern in 2005, are named after Greek myth characters. Nix is the goddess of darkness and Hydra is the many-headed monster in the underworld.

Now, if only the IAU can make up its mind on whether Pluto is a planet...

Why Genesis Crashed

NASA has released a report discussing the demise of the Genesis space probe. A set of gravity switches installed backwards did the space probe in as it re-entered the earth's atmosphere on September 8, 2004. Genesis was designed to collect solar wind atoms and return the samples back to earth after a 3-year mission. Because of the flawed switches, the Genesis crash landed on its re-entry. The container housing the samples cracked thereby exposing its payload to contamination.

The Genesis was launched on August 8, 2001 and began collecting samples on December of that year.

Google Earth's Birthday

Today is Google Earth's first birthday. Google Earth is the fine virtual globe program downloadable free from Google that has sent shivers to dictators and military men everywhere for its hi-res imagery of the earth's surface. I once used the software to locate the airfield of the famed Area 51 in Nevada, and a site even sponsors a contest to locate black helicopters (ostensibly the ones used in covert ops). The same site even reported that al Qaeda uses the software to stalk its targets.

With the new version, Google Earth 4, the software now runs on OS X and Linux, aside from its Windows flavor. Resolution was also improved, from 15 meters per pixel to 70 cm/pixel (some countries can be viewed at an amazing 10 cm per pixel). At this resolution you can well see Kim Jong Il's rump as he moons SoKor troops over the DMZ.

Lucy in the skies with diamonds

It has been reported that astronomers using data from Far Ultraviolet Spectroscopic Explorer, or FUSE, have deduced that planets may be orbiting the star Beta Pictoris, around 60 ly away from us. Beta Pictoris is said to be teeming with carbon, as such, the planets around it may have encrusted with diamonds as large as boulders.The planetary system and Beta Pictoris itself are relatively young, around 20 million years old.

I won't be surprised if they name the planets Lucy, deBeers, and Tiffany.

Ancient record of supernova explosion?

John Barentine of Apache Point Obsevatory is suggesting that ancient Native Americans may have recorded a supernova explosion in AD 1066. The purported record is carved in a rock found in Arizona. The petroglyph apparently shows an eight-pointed star and a scorpio, which according to Barentine, could be the supernova explosion that occured at the vicinity of Scorpius more than a millenia ago.


It could be a possibility, but it is not conclusive, as Barentine himself conceded. It is not clear whether ancient Native Americans see the constellation Scorpio as indeed something that looks like a scorpio, so the representation could be just coincidental. Who knows, maybe it was just a kid drawing a flower beside a scorpion?
