The International Astronomical Union (IAU) — the arbiter of planetary and satellite nomenclature since its inception in 1919 — recently approved a proposal from the MESSENGER Science Team to assign names to nine impact craters on Mercury. In keeping with the established naming theme for craters on Mercury, all of the newly designated features are named after famous deceased artists, musicians, or authors or other contributors to the humanities.

The newly named craters are

• Alver, for Betti Alver (1906-1989), an Estonian writer who rose to prominence in the 1930s, toward the end of Estonian independence and on the eve of World War II. She published her first novel, Mistress in the Wind, in 1927. She also wrote several short stories, poetry, and translations.

• Donelaitis, for Kristijonas Donelaitis (1714-1780), a Lutheran pastor who was considered one of the greatest Lithuanian poets. He is best known for The Seasons, considered the first classic Lithuanian poem. It depicts the everyday life of Lithuanian peasants. His other works include six fables and a tale in verse.

• Flaiano, for Ennio Flaiano (1910-1972), an Italian screenwriter, playwright, novelist, journalist, and drama critic especially noted for his social satires. He became a leading figure of the Italian motion-picture industry after World War II, collaborating with writer Tullio Pinelli on the early films of writer and director Federico Fellini.

• Hurley, for James Francis “Frank” Hurley (1885-1962), an Australian photographer and adventurer. He participated in several expeditions to Antarctica and served as an official photographer with Australian Imperial Forces during both world wars. The troops called him “the mad photographer,” because he took considerable risks to obtain photographs.

• L’Engle, for Madeleine L’Engle (1918-2007), an American writer best known for young-adult fiction, particularly the award-winning A Wrinkle in Time and its sequels: A Wind in the Door, A Swiftly Tilting Planet, Many Waters, and An Acceptable Time. Her works reflect both her Christian faith and her strong interest in modern science.

• Lovecraft, for Howard Phillips Lovecraft (1890-1937), an American author of horror, fantasy, and science fiction regarded as one of the most influential horror writers of the 20th Century. He popularized “cosmic horror,” the notion that some concepts, entities, or experiences are barely comprehensible to human minds, and those who delve into such topics risk their sanity.

• Petofi, for Sándor Petőfi (1823-1849), a Hungarian poet and liberal revolutionary. He wrote the Nemzeti dal (National Poem), which is said to have inspired the Hungarian Revolution of 1848 that grew into a war for independence from the Austrian Empire.

• Pahinui, for Charles Phillip Kahahawai “Gabby” Pahinui, (1921-1980), a Hawaiian guitar player considered to be one of the most influential slack-key guitar players in the world. His music was a key part of the “Hawaiian Renaissance,” a resurgence of interest in traditional Hawaiian culture during the 1970s.

• Roerich, for Nicholas Roerich (1874-1947), a Russian painter and philosopher who initiated the modern movement for the defense of cultural objects. His most notable achievement was the Roerich Pact of 1935, an international treaty signed by India, the Baltic states, and 22 nations of the Americas (including the United States), affirming that monuments, museums, scientific, artistic, educational, and cultural institutions and their personnel are to be considered neutral in times of war unless put to military use.

Ray Espiritu, a mission operations engineer on the MESSENGER team, submitted Pahinui’s name for consideration. “I wanted to honor the place where I grew up and still call home even after many years away,” he says. “The Pahinui crater contains a possible volcanic vent, and its name may inspire other scientists as they investigate the volcanic processes that helped to create Mercury, just as investigation of Hawaiian volcanoes helps us understand the volcanic processes that shape the Earth we know today.”
These nine newly named craters join 95 other craters named since the MESSENGER spacecraft’s first Mercury flyby in January 2008.

“We are delighted that the IAU has once again assigned formal names to a new set of craters on Mercury,” adds MESSENGER Principal Investigator Sean Solomon of Columbia University’s Lamont-Doherty Earth Observatory. “These names will make it easier to discuss these features in the scientific literature, and they provide a fresh opportunity to honor individuals who have contributed to the cultural richness of our planet.”

MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) is a NASA-sponsored scientific investigation of the planet Mercury and the first space mission designed to orbit the planet closest to the Sun. The MESSENGER spacecraft launched on August 3, 2004, and entered orbit about Mercury on March 17, 2011 (March 18, 2011 UTC), to begin a yearlong study of its target planet. MESSENGER’s extended mission began on March 18, 2012, and ended one year later. A possible second extended mission is currently under evaluation by NASA. Dr. Sean C. Solomon, the Director of Columbia University’s Lamont-Doherty Earth Observatory, leads the mission as Principal Investigator. The Johns Hopkins University Applied Physics Laboratory built and operates the MESSENGER spacecraft and manages this Discovery-class mission for NASA.

Gemini Planet Imager Flexure Jig Mounting from Franck Marchis on Vimeo.

This new setting is an important step in the integration of GPI, since it will allow astronomers to test the instrument in more realistic conditions. Because GPI will be mounted on the Cassegrain focus of the 8m-class telescope, the 2-ton instrument will move with the telescope. After studying the instrument’s behavior  for more than a week, the team is glad to report that the first results are promising and the instrument is stable despite the effect of gravity.

Combining adaptive optics, coronagraphy and spectroscopic capabilities, GPI will be capable of imaging and studying the light coming from Jupiter-sized exoplanets in orbit around nearby young stars. It will also study disks of dust from comet or asteroid belts around those stars, potentially detecting structure caused by even smaller planets. Individual opto-mechanical components of GPI must remain aligned to within 2 microns – 1/10th the diameter of human hair – over the course of an hour-long observation of a target, even as the telescope moves to track stars. The goal of this new set up is to study those effects. After four weeks of testing on the flexure jig and crane, GPI will be moved into a giant refrigerator to show that it can remain operating and aligned even under cold mountain-top conditions.

GPI is one of the major projects in the field of exoplanetary science with the involvement of ~60 researchers from 15 institutions (Lawrence Livermore National Laboratory, University of California, Santa Cruz, University of California, Berkeley , University de Montreal, STSCI, SETI Institute, Herzberg Institute of Astrophysics, American Museum of Natural History, University of California, Los Angeles, Dunlap Institute, Jet Propulsion Laboratory, Arizona State University and University of Georgia.). The instrument is scheduled to be shipped to Chile in the second semester of 2013 and will have its first light shortly after. Until then, the GPI team is making sure that the instrument is properly understood and the data processing pipeline is working fine. There is not a day that goes by that I don’t wonder how many exoplanets we will find with GPI…

Clear Skies,

Yes, there are more and more women in science, some of them even reaching the highest level of responsibility in their field.  One of the issues is that women are not as vocal as the men with a similar job. Is  that a secondary effect due to  years of being the underdog in a field, hence spending your energy fighting against stereotypes and nasty comments? Or it is simply because after getting the recognition of your peers, women enjoy their work and make the best of it? The main issue is that all kids need examples when they grow up, and highlighting  woman scientists could help girls think that they can also achieve their dream and become scientists, engineers, astronauts or a successful business woman.

This long preamble brings me to my idea. On Friday March 8, we should make sure that the women in our institutions enjoy a coffee or a lunch. Let them talk and exchange their thoughts, and take pictures to show the world that there are women in science, and sharing their experience on Twitter and Google+  (hashtag #WomenOfScience). They are here, not a majority, but they are an important part of scientific work and discussion.

I look forward to seeing pictures from your institution. SETI Institute will post pictures on their Twitter/Facebook/Google+ accounts as well.

Meteor captured from a dashboard camera near Chelyabinsk, Russia

What do we know?
(I collected these pieces of information from numerous of my colleagues. Thanks)

Today February 15 2013 a meteor exploded over the region of Chelyabinsk, Russia near the Southern Ural Mountains at 9:20:26 am LT (03:20:26 UTC). The explosion  occurred at an altitude of ~15-20 km  and the bolide impact speed was estimated to ~20 km/s with a trajectory oriented from North-East to South-West. Almost instantaneously,  several recordings of the meteor impact were available on the web, thanks to the presence of dashcam in most of the Russian cars and also because this part of Russia is heavily populated. On a side note, this event puts an end to any romantic Valentin Day’s dinner that most of the Californian astronomers had planned, since it was still Feb 14 for us.

The explosion, or sonic boom, was recorded by several instruments including an infrasound station from University of Western Ontario, USGS seismometers  and the Meteosat-9 geostationnary satellite.   The blast caused significant damage in the area (see the video above) and several hundred of people were injured, mostly because the shockwave blewout windows. I read one report of a factory building with a collapsed roof.   The contrail has this weird dual shape, possibly because the meteoroid split in half shortly after entering in Earth’s atmosphere.

The entry of the meteor was definitely at low angle, so the blast is due to the sonic boom, not to a direct impact. In other words, the meteor fragmented in Earth’s atmosphere. The presence of several small impact craters has been mentioned but not confirmed yet. One of them is a hole in a frozen lake and the Russian media reported that divers will start tomorrow to search for fragments at the bottom of the lake.

The big picture

There are several back-of-the-envelop estimates of the size and mass of the body but roughly the bolid had a diameter of 15m, a Mass of 7,000 tons (assuming a rocky density of 3 g/cc) . NASA scientists claim that the explosion was due to the largest rock crashing on the planet since Tunguska in 1908 (energy 10-15 MegaTons of TNT equivalent). Peter Brown, from University of Western Ontario determined a total energy of 300 kilotons of TNT equivalent  for the Russian meteor, so ~20 Hiroshima bombs.  It was  larger than  the Oct 2009 Indonesia event (50 kTons TNT  eq) and Sikhote-Alin fall (Feb 1947,  10 kTons TNT eq).  Interestingly, based on the statistical study of near-Earth asteroid population, we can estimate that a #RussianMeteor-like event should happen every ~30 years.

Potential damage to Earth from NEA impact. I added the Russian meteor on this graph (red square) with an energy of 300 kTons TNT eq, corresponding to a frequency of impact of 30 years. Adapted from LSST website. credit: A. Harris, SSI/LLST

The existing (Catalina Sky Survey, Pan STARRS) and future surveys (LSST) are dedicated to search for large impactors. These searches are motivated by the George E. Brown, Jr. Near-Earth Object Survey Act, which calls for NASA to detect 90 percent of NEOs with diameters of 140 meters or greater by 2020. As you can see on the graph above only ~10 percent of those asteroids have been discovered so far. For smaller ~15m asteroids equivalent to the #RussianMeteor, the survey is very incomplete since only 0.1 percent of those asteroids are known.

Should we spend our limited space money to build extremely large facilities to search for these small ~15m asteroids? I don’t think so, since we don’t have yet a complete understanding of the technologies needed to mitigate those events, and considering the current lack of financial resources, we should  be more imaginative than building larger aperture telescopes.

Our space budget could be better used on setting an alert systemsimilar to the existing ones for tsunamis, volcanoes, and in some countries earthquakes. They could help save life and avoid a disaster.What first comes to mind are current technologies over which we don’t have complete control such as nuclear power plants. A warning of a few minutes could be crucial to avoid major disaster in case of a impact with a >15m asteroid nearby a nuclear facility. The 2012 Fukishima nuclear power plant accident is a vivid example of catastrophic and worldwide ripple effects after a localized natural disaster. Without getting into those extreme cases, our society and its economy rely on  transportation (e.g. bridge, trains, commercial jets) that could  be affected by 15m-meteor impact, so an early warning system could save a lot of lives and reduce the number of injuries.

Spending a few hundred million of dollars to set up an alert network, an array of small telescopes around Earth(in space) should be a challenge we take up. We are aware of the danger coming from space, and should be wiling to mitigate it. The Canadian Agency is leading the effort on this topic with the development of NEOSSat, a micro-satellite dedicated to detecting and tracking asteroids and satellites, to be launched on February 25 2013.

Let’s also keep in mind that the cost of this alert system should be shared by most of the nations, since there is no borders from space.It was a bad day for Russia, and a clear reminder that space is not a friendly place.

Background

The AAS is a member of a coalition of 3,200 national organizations named NDD United. The coalition has worked actively to communicate to Congress that a balanced approach to deficit reduction is necessary and that significant cuts to the non-defense discretionary (NDD) portion of the federal budget called for by the 2011 balanced budget amendment in the form of a sequester would have wide-ranging and negative impacts. The sequester is scheduled to be implemented on March 1st.

The White House budget office estimates that this $85 billion sequester will require across-the-board cuts of five percent for non-defense discretionary programs and eight percent for defense discretionary programs. With only seven months left in FY 2013, the effective cuts for some programs could even reach nine percent for non-defense and 13 percent for defense. While we cannot predict specific programmatic impacts at this point, these additional cu ts will clearly mean fewer grants, deferred missions, layoffs of contractor personnel, and furloughs of Federal employees.

NDD United delivered a letter to Congress on February 11th  (http://publichealthfunding.org/uploads/NDD3200Letter.Final.Feb2013.pdf) and is calling for all members of the Coalition to speak out to their member of Congress via Twitter on Thursday, February 14th.

AAS members may also make contact directly by phone, fax, or letter, if they do not use Twitter or are unfamiliar with its use. Sending email is not an efficient way of communicating with Congress, so do not utilize this communication medium.

What You Can Do Today

The AAS asks all members to take a moment today to contact their members of Congress.

If you use Twitter, use your members’ twitter handle and the sample tweets below to make your voice heard. A slightly outdated but complete list of members’ twitter handles are available here: http://govsm.com/w/House and here: http://govsm.com/w/Senate.

If you’d prefer to make a call, send a FAX or write a letter, use the AAS’ Contacting Congress resource to find your members’ office numbers [ http://aas.org/contacting-congress ]. A brief message indicating that you want your member of Congress to take a balanced approach to deficit reduction and that you are against the sequester will be sufficient. Specifics are not required at this time.

Kepler Spacecraft and Photometer (credit: NASA)

On January 17, the team detected some recurrent frictions on the reaction wheel #4, since its complete failure would have mean the end of the mission, the telescope scientific operation was halted. Because in  its safe mode configuration, the spacecraft maintains its altitude using its thrusters only, the reaction wheels stop spinning and the lubricant got a chance to spread uniformly inside the wheels, returning the spacecraft to nominal operation. The engineering team took this decision by scrutinizing the activity on the wheels after one of them failed in July 2012.

The transition from safe mode to normal operation happened without any issues and Kepler telescope started collecting data again on January 28 at 5 pm PST. This is a great job done by Kepler engineers which reminds us the challenges of space exploration.

I am confident that more exoplanet discoveries are on the way, and this good news is a relief for the community of exo-planetary astronomers and their friends.

Live long and prosper Kepler!

Franck Marchis

The team detected an increase of friction on reaction wheel #4 on January 11 2013 just after the completion of Quarter 15 flight operation. This friction persisted after the spacecraft roll, which could lead to the complete failure of the wheel.

To solve this issue, the team reported to have placed the Kepler spacecraft in a “wheel rest” safe mode. Science operation has been interrupted and the spacecraft is now in a position which does not require the use of the reaction wheels. They hope that by resting the wheel for 10 days, the internal lubricant will be redistributed and the wheel will work again in an optimal manner.

The spacecraft was equipped with four reaction wheels, three of them are needed for the pointing of the telescope and the fourth one was installed as a backup. If this damaged wheel completely fails, the mission is over. In other words, the spacecraft will be unable to stabilize its pointing and the mission will stop fulfilling its scientific objectives.

Problems with reaction wheels seem quite common on spacecrafts recently. Dawn, another NASA mission designed to explore Vesta and Ceres, also lost two of his reaction wheels this year. Because this spacecraft does not need a pointing as accurate as Kepler, the problem was solved by developing a hybrid strategy relying on two reaction wheels and the thrusters of the probe. I have been told that a similar solution is unfortunately not possible for the Kepler spacecraft.

The Kepler mission has been approved for extension until 2016, providing four additional years to find Earth-sized exoplanet in the habitable zone of their stars. The mission therefore already completed its optimal operation time, so it is not surprising that engineering problems are now appearing.  Outer space is not an easy place to be.

Last week, the mission team announced the discovery of 461 additional planet candidates, including two in the Habitable zone of their stars. The Kepler spacecraft is the most prolific planet-hunter so far, with a total number of 2,321 planet-candidates among 3,130 known exoplanets.

We discussed yesterday with Jon Jenkins the recent discoveries of Kepler. He mentioned the latent problem with those reaction wheels, so I am assuming that the entire team, including several SETI scientists, is anxious to know how Kepler will “feel” after this 10-day break.

Last week the French space agency, CNES, announced that COROT, another planet hunter spacecraft was also malfunctioning, and most likely will end the mission officially soon.

Are we witnessing the end of the pioneer planet hunters? I hope not, it is difficult to imagine a world of astronomy without Kepler.

In a nutshell, no telescopes have suffered major damages from the bush fire, but the astronomer’s lodge, the visitor’s center and several staff houses have been destroyed or seriously damage.

The NSW rural fire service posted several pictures of the observatory taken on the morning.  It could have been worst, since it is visible from the pictures that the fire approached dangerously the telescope domes.

Hopefully, after the reconstruction of the staff buildings, the observatory will be fully operational again. We avoided the worst at Siding Spring Observatory last night and most astronomers, including myself, are happy not to have to mourn the disappearance of a unique facility.

Siding Spring Observatory part of  Australian National University (ANU)  is home of several telescopes including the Anglo-Australian Telescope (AAT), a 3.9m optical telescope, and the largest one in Australia, but also the 2.0 m Faulkes Telescope South of Las Cumbres Observatory (LCOGT), and the exoplanet finder HAT-south telescope.

Thankfully, the people who worked at the observatory have been evacuated on time (source Peter Verwayen).

Everyone evacuated safely from @sidingspring. Sorry, I had no time for photos but I can say it wasn’t a good place to be!

— Peter Verwayen (@SSOPete) January 13, 2013

These telescopes are equipped with weather stations and webcams, used by astronomers to monitor the weather and check the status of the telescope remotely.  It is still possible to follow what is going on at the observatory.

The weather station at AAT displayed a spike reaching ~100 deg C, but it quickly dropped and at the time I am writing these lines, this trend is continuing, so this may be a good news.

The webcams of the Faulkes Telescope at 12:08 PT show that the fire did not reach this telescope.

Since we are still getting data from these instruments, the fire may have not reached these facilities (AAT, Faulkes & HAT). The best way to know what is going on at Siding Spring is to follow Twitter, and the accounts of Michel Bannister (@astrokiwi), Amanda Bauer (@astropixie), Bryan Gaesler (@SciBry) and Brian Schmidt (@Cosmicpinot).

I remember vividly when 10 years ago the Mount Stromlo Observatory (MSO), another Australian Observatory, was devastating by a firestorm, which destroyed most of the telescopes and houses and offices of my colleagues and friends. I sincerely hope this observatory will be spared from the destruction and tomorrow, when the employees will be allowed to come back, they will find only minor damages.

I am keeping my fingers crossed and I wish to all of you clear skies, especially in Australia.

I gathered below a few tweets posted by my colleagues while they were listening to Jim Green’s talk. Thanks to Emily Lakdawalla from the Planetary Society for pointing out the live-tweeting of Nicholas Heavens (@weatheronmars). I added as well a few tweets from @LeighFletcher.

In a nutshell, Jim Green did not announce a new mission toward Europa… From these tweets, I have the sense that he took this opportunity to reply to the special edition of the Planetary Exploration Newsletter (US PLANETARY PROGRAM POISED TO LOSE A GENERATION OF SCIENTISTS) and discuss with the Outer Planet Scientists the best strategy to get in the future a Flagship mission toward an outer planet body.

I will update this post with new tweets if I find any, and inputs from my colleagues.
