This image, right here, shows us the value of long-term observations. It’s a composite of pictures taken between 1999 and 2012 from NASA’s Chandra X-ray Telescope. Put 9.5 days’ worth of observations together, and you can see a lot of action in Centaurus A — namely, a huge jet emanating from a ginormous black hole embedded in the galaxy.

“As in all of Chandra’s images of Cen A, this one shows the spectacular jet of outflowing material – seen pointing from the middle to the upper left – that is generated by the giant black hole at the galaxy’s center. This new high-energy snapshot of Cen A also highlights a dust lane that wraps around the waist of the galaxy. Astronomers think this feature is a remnant of a collision that Cen A experienced with a smaller galaxy millions of years ago,” NASA stated.

A past survey of X-ray sources in Cen A revealed that most of them are black holes or neutron stars (the latter created from the wake of a huge star’s collapse). It seems that most of these sources are either less than twice the mass of the sun, or more than five times as massive. Here’s the more interesting bit: the smaller ones appear to be neutron stars, and the bigger ones black holes.

“This mass gap may tell us about the way massive stars explode. Scientists expect an upper limit on the most massive neutron stars, up to twice the mass of the Sun,” NASA added.

“What is puzzling is that the smallest black holes appear to weigh in at about five times the mass of the Sun. Stars are observed to have a continual range of masses, and so in terms of their progeny’s weight we would expect black holes to carry on where neutron stars left off.”

Robots And Astronauts Feature In First Glimpse of Canada’s New Space Policy

About six years ago, the Canadarm — Canada’s iconic robotic arm used in space — was almost sold to a company in the United States, along with other space technology from MacDonald, Dettwiler and Associates. The Canadian government blocked the sale and swiftly came out with a promise: a space policy to better support Canada’s industry.

That promise was made in September 2008. “Time is of the essence,” then-Industry Minister Jim Prentice told reporters upon announcing a space policy would be created. Today, 65 months later, the government released the high-level framework of that policy. Astronauts, telescopes and yes, the Canadarm are all prominently mentioned in there.

A lot has happened in six years. Policy-makers used to cite successor Canadarm2’s role in space station construction. Now the arm also does things that were barely imaginable in 2008 — namely, berthing commercial spacecraft such as SpaceX’s Dragon at the International Space Station. It shows how quickly space technology can change in half a decade.

At 13 pages, there isn’t a lot of information in Canada’s framework yet to talk about, but there are some statements about government priorities. Keep the astronaut program going (which is great news after the success of Chris Hadfield). A heavy emphasis on private sector collaboration. And a promise to keep funding Canada’s contribution to the James Webb Space Telescope, NASA’s next large observatory in space.

These are the Top 5 priorities listed in the plan:

  • Canada First: Serving Canada’s interests of “sovereignty, security and prosperity.” As an example: The country has a huge land-mass that is sparsely populated, so satellites are regularly used to see what ship and other activity is going on in the territories. This is a big reason why the Radarsat Constellation of satellites is launching in 2018.
  • Working together globally: Canada has a tiny space budget ($488.7 million in 2013-14, $435.2 million in 2014-15 and $382.9 million in 2015-16), so it relies on other countries to get its payloads, astronauts and satellites into space. This section also refers to Canada’s commitment to the International Space Station, which (as with other nations) extends to at least 2024. That’s good news for astronauts Jeremy Hansen and David Saint-Jacques, who are waiting for their first trip there.
  • Promoting Canadian innovation: The James Webb Telescope (to which Canada is contributing optics and a guidance system) is specifically cited here along with the Canadarm. Priority areas are Canada’s historic strengths of robotics, optics, satellite communications, and space-based radar, as well as “areas of emerging expertise.”
  • Inspiring Canadians: Basically a statement saying that the government will “recruit, and retain highly qualified personnel,” which in more real terms means that it will need to keep supporting Canadian space companies financially through contracts, for example, to make this happen.

That last point in particular seemed to resonate with at least one industry group.

“A long-term strategic plan for Canada’s space program is critical for our industry. In order to effectively invest in innovation, technology and product development, we rely heavily on knowing what the government’s priorities for the space program are,” stated Jim Quick, president of the Aerospace Industries Association of Canada (a major group that represents the interests of private space companies.)

While we wait for more details to come out, here’s some valuable background reading. The space-based volume of the Emerson Report (the findings of a government-appointed aerospace review board listed in 2012) called for more money for and more stable funding of the Canadian Space Agency, among other recommendations.

And here’s the government’s point-by-point response in late 2013. In response to funding: “The CSA’s total funding will remain unchanged and at current levels. The government will also leverage existing programs to better support the space industry.” Additionally, the CSA’s space technologies development program will be doubled to $20 million annually by 2015-16, which is still below the Emerson report’s recommendation of adding $10 million for each of the next three years.

What are your thoughts on the policy? Let us know in the comments.

Surprise! Brown Dwarf Star Has Dusty Skies, Appearing Strangely Red

Dust clouds on a brown dwarf or “failed star” are making it appear redder than its counterparts, new research reveals. Better studying this phenomenon could improve the weather forecast on these objects, which are larger than gas giant planets but not quite big enough to ignite nuclear fusion processes to become stars.

“These are not the type of clouds that we are used to seeing on Earth. The thick clouds on this particular brown dwarf are mostly made of mineral dust, like enstatite and corundum,” stated Federico Marocco, who led the research team and is an astrophysicist at the United Kingdom’s University of Hertfordshire.

Using the Very Large Telescope in Chile as well as data analysis, “not only have we been able to infer their presence, but we have also been able to estimate the size of the dust grains in the clouds,” he added.

The brown dwarf (known as ULAS J222711-004547) has an unusual concoction in its atmosphere of water vapor, methane, (likely) ammonia and these mineral particles. While scientists are only beginning to wrap their head around what’s going on in the atmosphere, they noted that the size of the dust grains can influence the color of the sky and make it turn redder.

“Being one of the reddest brown dwarfs ever observed, ULAS J222711-004547 makes an ideal target for multiple observations to understand how the weather is in such an extreme atmosphere,” stated Avril Day-Jones, an astrophysicist at the University of Hertfordshire who co-authored the paper.

“By studying the composition and variability in luminosity and colours of objects like this, we can understand how the weather works on brown dwarfs and how it links to other giant planets.”

You can read more about the research in the Monthly Notices of the Royal Astronomical Society or in preprint version on Arxiv.

And by the way, there’s been other exciting work lately in brown dwarfs; another group recently released the first weather map of another failed star (and we have some information on Universe Today on how that was done, too!) Also, there are other weird brown star atmospheres out there, as this 2013 find shows.

Milky Way-Mapping Telescope Nabs Its First Pictures In Space

From a lonely outpost in space, the European Space Agency’s Gaia telescope is getting ready to map out the Milky Way. It will take some time to calibrate the instruments to make sure they’re ready for work, however, and that’s why you’re looking at the image above.

Controllers aimed the telescope at the Large Magellanic Cloud, which is a satellite galaxy to our own Milky Way, and snapped this picture of star cluster NGC 1818.

“This test picture, taken as part of commissioning the mission to ‘fine tune’ the behaviour of the instruments, is one of the first proper ‘images’ to be seen from Gaia, but ironically, it will also be one of the last, as Gaia’s main scientific operational mode does not involve sending full images back to Earth,” ESA stated.

This is one crucial step along the road to making sure Gaia’s measurements are accurate. In the next five years, it will examine a billion stars (an astounding number, but still only 1 percent of the galaxy’s population). Gaia will build up a database of key stellar properties such as brightness, what it is made of and temperature.

For more information on Gaia, check out this past Universe Today story from its Dec. 19 launch as well as the official Gaia blog.

A History of Curious Artifacts Sent Into Space

A penny for Mars... Credit: NASA/JPL-Caltech.

Since the dawn of the Space Age in 1957, thousands of artifacts and memorabilia have been flown into space. Some have been hoisted on brief suborbital flights, while others have been flung out of the solar system, never to return. And of course, it’s become a fashionable — and highly commercialized — trend as of late to briefly loft products, stuffed animals, etc via balloon towards the tenuous boundary of space. Fly a souvenir or artifact into orbit, and it goes from mundane to priceless. But a few may also serve as a final testament to the our ephemeral existence as a species long after our passing.

Here’s a look at some of the most memorable objects sent into space:

New Horizons Memorabilia

Launched on January 19th, 2006, New Horizons is headed towards a historic encounter with Pluto and its moons next year. From there, New Horizons will survey any Kuiper Belt objects of opportunity along its path and then head out of the solar system, becoming the fifth spacecraft to do so. In addition to a suite of scientific instruments, New Horizons also carries the ashes of Pluto discoverer Clyde Tombaugh, a Florida & Maryland state quarter, a piece of Scaled Composites SpaceShipOne, and an American flag. These will doubtless confuse any extraterrestrial salvagers!

The Pioneer Plaques

The first spacecraft sent on escape trajectories out of our solar system, the Pioneer 10 and 11 spacecraft each carry a plaque which serves as a sort of postcard “greeting” to any future interceptors. The plaque depicts a diagram of the solar system, a map of our location in the galaxy using the positions of known pulsars, and a nude man & woman, which actually generated lots of controversy.  Scientist James Van Allen tells of deliberately placing a fingerprint on the Pioneer 10 plaque in his biography The First Eight Billion Miles.

The Voyager 1 and 2 Golden Records

Conceived and designed in part by Carl Sagan, these records contain images and sounds of the Earth that’ll most likely outlive humanity. The records carry greetings in 55 languages, music ranging from Mozart to Chuck Berry, 116 images and more, along with instructions and a stylus for playback.  The record is also enclosed in an aluminum cover electroplated with Uranium-238, which an alien civilization could use to date its manufacture via half-life decay.

The Mars Curiosity Penny

Strange but true: The Mars rover Curiosity carries a 1909 U.S. Penny for a backup camera calibration target.  The penny itself is embedded just below the primary color calibration targets used by Curiosity’s MArs Hand Lens Imager (MAHLI). Rare enough on Earth, the 1909 Lincoln “Mars penny” will be priceless to future collectors!

Juno’s LEGO Figurines

Mini-figurines of Galileo and the Roman deities Jupiter and Juno were launched in 2011 aboard NASA’s Juno spacecraft en route to Jupiter . LEGO has flown products aboard the U.S. Space Shuttles and to the International Space Station previously, but Juno’s cargo represents the “most distant LEGO launch” ever. The figurines will burn up in Jupiter’s atmosphere along with the spacecraft at the end of the mission in October 2017.

Apollo 15 Postal Covers Fiasco

Apollo 15 astronauts got in some hot water over a publicity scheme. The idea that stamp collector and dealer Hermann Sieger approached the astronauts with was simple: 400 commemorative postage stamp covers would be postmarked at point of departure from the Kennedy Space Center and again at the return point of arrival aboard the USS Okinawa after their circuitous journey via the Moon. NASA was less than happy with the whole affair, and Command Module Pilot Al Worden recounts the aftermath in his book, Falling to Earth.

Haiku for MAVEN

Last year’s MAVEN mission to Mars also carried haiku submitted by space fans.  Over 12,530 valid entries were submitted and over 1,100 haiku received the necessary minimum of two votes to be included on a DVD disk affixed to the spacecraft. MAVEN reaches orbit around Mars in October 2014.

Luna 2: A Russian Pennant on Moon

On September 12th, 1959, the Soviet Union’s Luna 2 spacecraft became the first man-made object to impact the Moon. Luna 2 carried two spherical “pennants” composed of pentagon-shaped elements engraved with the USSR Coat of Arms and Cyrillic letters translating into “CCCP/USSR September 1959.” An identical pennant is now on display in the Kansas Cosmosphere.

A GeoSat Time Capsule Aboard EchoStar XVI

A disk entitled Last Pictures similar to the Voyager records was placed on a satellite headed to geosynchronous orbit in 2012. Launched aboard EchoStar XVI, Last Pictures is an ultra-archival disk containing 100 snapshots of modern life along with interviews with several 21st century artists and scientists.  Geosynchronous satellites aren’t subject to atmospheric drag,  and may be the last testament to the existence of humanity on Earth millions of years hence.

Lunar Prospector Carries An Astro-Geologist’s Ashes to the Moon

Though he never made the selection to become an astronaut, scientist Eugene Shoemaker did make a posthumous trip to the Moon.  The Lunar Prospector spacecraft departed Earth with Shoemaker’s ashes on January 7th, 1998 in a capsule wrapped in brass foil. Lunar Prospector impacted the south pole of the Moon on July 31st, 1999.

SpaceX Takes Star Trek Actor to Space

The ashes actor James Doohan (AKA Scotty) were launched aboard a 2012 SpaceX flight to the International Space Station. The COTS Demo Flight, or COTS 2, was the first commercial spacecraft to berth at the ISS. SpaceX had flown a small amount of Doohan’s ashes on the 2008 unsuccessful test launch of the Falcon 1 rocket.

Cheese Wheel Makes a Suborbital Journey

All eyes were also on SpaceX during their December 8th 2010 maiden flight of the Dragon space capsule. And the hinted mystery cargo? None other than a wheel of cheese, a nod by SpaceX CEO Elon Musk to a classic Monty Python sketch.

The Apollo 12 “Moon Museum”

Did it really go into space? One of the legends surrounding the Apollo program is the existence of what’s been dubbed the “Moon Museum.”  This was a postage stamp-sized “gallery” of art which included a sketch by Andy Warhol and other 1960s artists that was supposedly attached to descent stage of Apollo 12 and left on the Moon.  It will be up to future lunar visitors to confirm or deny its existence!

…And lastly, I give you the “Space Hubcap”

Was the first man-made object propelled into space actually a 1 ton armor plate? On August 27th, 1957 — just two months prior to Sputnik 1 — the Pascal-B underground nuclear test was conducted in southern Nevada.  During the explosion, a steel plate cap was blasted off of a test shaft. The plate could be seen in the initial high-speed video frames, and it was estimated to have reached a speed six times the sufficient escape velocity to depart Earth. To this day, no one knows if this strange artifact of early Space Age folklore still roams the void of space, or simply vaporized due to atmospheric compression at “launch”.

 

 

Black Holes Warmed Up Space Slower Than Previously Thought: Study

Black holes are big influencers for the early universe; these singularities that were close to ancient stars heated up gas and affected star formation across the cosmos. A new study, however, says that heating happened later than previously thought.

“It was previously believed that the heating occurred very early, but we discovered that this standard picture delicately depends on the precise energy with which the X-rays come out,” stated Rennan Barkana, a co-author of the paper who is an astronomer at Tel Aviv University.

“Taking into account up-to-date observations of nearby black-hole binaries changes the expectations for the history of cosmic heating. It results in a new prediction of an early time (when the universe was only 400 million years old) at which the sky was uniformly filled with radio waves emitted by the hydrogen gas.”

These so-called “black-hole binaries” are star pairs where the larger star exploded into a supernova and left behind a black hole. The strong gravity then yanked gas away from the stellar companion, emitting X-rays in the process. The radiation, as it flows across the universe, is cited as the factor behind gas heating in other parts of space.

You can read more details of the model in the journal Nature. The study was led by Anastasia Fialkov, a fellow TAU researcher.

Mariner 10: Best Venus Image and 1st Ever Planetary Gravity Assist – 40 Years Ago Today

Exactly 40 Years ago today on Feb. 5, 1974, Mariner 10, accomplished a history making and groundbreaking feat when the NASA science probe became the first spacecraft ever to test out and execute the technique known as a planetary gravity assisted flyby used to alter its speed and trajectory – in order to reach another celestial body.

Mariner 10 flew by Venus 40 years ago to enable the probe to gain enough speed and alter its flight path to eventually become humanity’s first spacecraft to reach the planet Mercury, closest to our Sun.

Indeed it was the first spacecraft to visit two planets.

During the flyby precisely four decades ago, Mariner 10 snapped its 1st close up view of Venus – see above.

From that moment forward, gravity assisted slingshot maneuvers became an extremely important technique used numerous times by NASA to carry out planetary exploration missions that would not otherwise have been possible.

For example, NASA’s twin Voyager 1 and 2 probes launched barely three years later in 1977 used the gravity speed boost to conduct their own historic flyby expeditions to our Solar Systems outer planets.

Without the flyby’s, the rocket launchers thrust by themselves did not provide sufficient interplanetary speed to reach their follow on targets.

NASA’s Juno Jupiter orbiter just flew back around Earth this past October 9, 2013 to gain the speed it requires to reach the Jovian system.

The Mariner 10 probe used an ultraviolet filter in its imaging system to bring out details in the Venusian clouds which are otherwise featureless to the human eye – as you’ll notice when viewing it through a telescope.

Venus surface is completely obscured by a thick layer of carbon dioxide clouds.

The hellish planet’s surface temperature is 460 degrees Celsius or 900 degrees Fahrenheit.

Following the completely successful Venus flyby, Mariner 10 eventually went on to conduct a trio of flyby’s of Mercury in 1974 and 1975.

It imaged nearly half of the planets moon-like surface, found surprising evidence of a magnetic field, discovered that a metallic core comprised nearly 80 percent of the planet’s mass, and measured temperatures ranging from 187°C on the dayside to minus 183°C on the nightside.

Mercury was not visited again for over three decades until NASA’s MESSENGER flew by and eventually orbited the planet – and where it remains active today.

Mariner 10 was launched on Nov. 3, 1973 from the Kennedy Space Center atop an Atlas-Centaur rocket.

Shortly after blastoff if also took photos of the Earth and the Moon.

Ultimately it was the last of NASA’s venerable Mariner planetary missions hailing from the dawn of the Space Age.

Mariner 11 and 12 were descoped due to congressional budget cuts and eventually renamed as Voyager 1 and 2.

The Mariner 10 science team was led by Bruce Murray of the Jet Propulsion Laboratory (JPL), Pasadena, Calif.

Murray eventually became the Director of JPL. After he passed away in 2013, key science features on Martian mountain climbing destinations were named in his honor by the Opportunity and Curiosity Mars rover science teams.

Stay tuned here for Ken’s continuing LADEE, Chang’e-3, Orion, Orbital Sciences, SpaceX, commercial space, Mars rover and more planetary and human spaceflight news.

If you love talking about space — and as a reader of Universe Today, I really hope you do — there’s an awesome podcast for you to add to your playlist. 365 Days of Astronomy puts out an astronomy-themed episode every single day of the year, covering everything from recent discoveries, to folklore, to community events.

If you’ve got a microphone and a desire to contribute, or have at least some coffee money to contribute to charity, they’d really love to hear from you as they enter a sixth (sixth!) year of operation. More details are below the jump.

Full disclosure here: Universe Today is a big supporter of 365 Days of Astronomy, and I’ve been contributing podcasts myself since last year. It is an awesome experience. Pamela Gay (who oversees the project through her astronomy education organization, Cosmoquest) is inspiring to work for as she is a tireless supporter of bringing the joy of space to the general public.

Nancy Atkinson (a fellow contributor and UT senior editor) joked to me today, “It’s kind of like the Mars rovers — the Energizer Bunny of podcasts.” And it’s through your support that we can keep going, and going, and going. Here’s the official press release with information about contributions:

The 365 Days of Astronomy Podcast is a project that will publish one podcast per day, for all 365 days of 2011. The podcast episodes are written, recorded and produced by people around the world.

365 Days of Astronomy will continue its service in 2014! This time we will have more days available for new audio. Have something to share? We’re looking for content from 10 minutes long up to an hour! Since 2009, 365 Days of Astronomy has brought a new podcast every day to astronomy lovers around the world to celebrate the International Year of Astronomy. Fortunately, the project has continued until now and we will keep going for another year in 2014. This means we will continue to serve you for a 6th year.

Through these years, 365 Days Of Astronomy has been delivering daily podcasts discussing various topics in the constantly changing realm of astronomy. These include history of astronomy, the latest news, observing tips and topics on how the fundamental knowledge in astronomy has changed our paradigms of the world. We’ve also asked people to talk about the things that inspired them, and to even share their own stories, both of life doing astronomy and science fiction that got them imagining a more scientific future.

365 Days of Astronomy is a community podcast that relies on a network of dedicated podcasters across the globe who are willing to share their knowledge and experiences in astronomy with the world and it will continue that way. In 2013, 365 Days of Astronomy started a new initiative with CosmoQuest. We now offer great new audio every weekend, while on weekdays we serve up interesting podcasts from CosmoQuest and other dedicated partners. We also have several monthly podcasts from dedicated podcasters and have started two new series: Space Stories and Space Scoop. The former is a series of science fiction tales, and the latter is an astronomy news segment for children.

From the universe to the solar system, we’ve had an interesting journey, especially the ostensibly legendary comet ISON which finally ended its days by breaking apart and vaporizing. We hope we won’t end like ISON did! As for 2014, we will have more available days for new podcasts.

For this upcoming year, the 365 Days of Astronomy podcast is looking for individuals, organizations, schools, companies, and clubs to sign-up for their 5 – 60 minutes of audio for the new daily podcast which will be aired on Tuesday, Thursday, Saturday, and Sunday. As for Monday, Wednesday, and Friday, we will air audio podcasts from CosmoQuest and partners’ Google+ hangouts. We’ll also post the matching video submissions on our YouTube Channel.

We will once again continue our quest in the podcasting arena, but we need your support to be a success. The project is now accepting financial support from individuals as well as organizations to cover our audio engineering and website support costs. The podcast team invites people and organizations to sponsor shows by donating to support one day of the podcast. It costs us about $45 per show. For your donation of $30, a dedication message will be announced in the beginning of the show. For a $15 donation a sponsorship message will be heard at the end of the show. Alternatively, for a $100 donation a sponsor may request a dedication message at the end of a whole week of programs. These donations are essential to cover the price for editing and posting podcasts.

The 365 Days of Astronomy podcast is heard by 5,000 listeners per day and by 2013 we have surpassed 6,8 million downloads. In 2009, the project was awarded a Parsec Award as “The Best Infotainment” podcast and a year later, in 2010-2012, it was nominated for the “Best Fact Behind the Fiction” award.

The first launch of February 2014 worldwide is about to light up the night skies over the Baikonur Cosmodrome in Kazakhstan, with the launch of a Soyuz-U rocket carrying the uncrewed Progress M-22M spacecraft to the ISS. You can watch the launch live here, as well as the “fast-track” docking just 5 hours and 58 minutes later.

Progress will be carrying 2.8 tons of fuel, oxygen, supplies and experiments to the International Space Station. This will be the 54th Progress flight to the International Space Station since the first Progress launch to the station in 2000.

The launch is set to occur at 16:23:33 Universal Time or 11:23:33 AM EST. NASA TV will go live with the launch at 11:00 AM EST/16:00 UT, and TV Tsenki will also broadcast video from the pad just prior, though the broadcast frequently its sans audio.

Progress is also on a four orbit “fast-track” launch headed to the International Space Station. Tune in to NASA TV at 5:00 PM EST/22:00 UT later today, and you’ll be able to catch the docking of the Progress spacecraft to the Pirs module of the ISS as well. Docking is set to occur at 5:25 PM EST/22:25 UT over the North Atlantic Ocean.

Fun fact: Neil Armstrong still holds the record for the fastest journey from liftoff to docking at 5 hours and 33 minutes during Gemini 8 way back in 1966.

Update: ISS Astros indeed report during the live broadcast of the launch of Progress M-22M on NASA TV today of catching sight of the first stage of the Soyuz-U at liftoff… we’ll post any pics if and when they surface.

Progress M-20M undocked from the same Pirs compartment earlier this week on Monday in order to make way for the arrival of Progress M-22M. Progress M-20M is still in orbit, and is slated for a fiery destructive reentry on February 11th over the South Pacific. The long span between undocking and reentry for Progress M-20M allows for experiments on the spacecraft’s attitude control system to be carried out by ground controllers.

This also marks the start of a busy 2014 season at the International Space Station. On March 1st, SpaceX continues its contract to resupply the station with the launch of a Falcon 9 rocket with its fifth Dragon capsule making its third operational delivery to the station on CRS-3. Then later in March on the 12th, Expedition 38 crewmembers Oleg Kotov, Sergey Ryazansky, and NASA astronaut Michael Hopkins will return to Earth aboard Soyuz TMA-10M. The next crewed launch headed to the International Space Station are Expedition 39 cosmonauts Alexander Skvortsov, Oleg Artemyev, and NASA astronaut Steve Swanson launching from Baikonur on March 26th on Soyuz TMA-12M.

Progress M-22M is ultimately slated to undock from the Pirs module of the International Space Station on April 7th for a destructive reentry over the South Pacific.  Three additional SpaceX launches utilizing Dragon capsules and two more launches of Orbital Science’s Cygnus cargo spacecraft will be conducted in 2014, as well as visits by the European Space Agency’s ATV-5 Georges Lemaitre in June and JAXA’s HTV-5 in July.

And another launch from the Baikonur Cosmodrome is coming right up on Valentine’s Day, February 14th, with the liftoff of an International Launch Services Proton rocket carrying the Turksat 4A satellite. The launch will be carried live via the ILS website and is slated for 21:09 UT/4:09 PM EST.

And though these are all standard resupply missions to the International Space Station, spaceflight is anything but routine. Avid trackers of live launches will remember the Progress M-12M spacecraft that was lost shortly after launch back in August 2011. To date, Progress M-12M was the only supply craft that failed to reach the International Space Station. Progress M-12M impacted in the Choisk Region of Russia’s Altai Republic in the Far East. The RD-0110 engine began to experience a flight anomaly just over five minutes after launch, causing the flight computer to execute a termination of thrust. Progress M-12M was the first loss of a Progress spacecraft since the start of the program in 1978. Ironically, Progress M-12M carried among its cargo manifest 10 paintings made by the son of Russian artist Alesandr Shilov said to be for “the psychological support of the crew…” There’s also a small cottage industry in Siberia east of Russian launch sites in salvaging rocket parts and boosters for scrap metal as they plummet from the sky.

It’s also possible to spot these spacecraft from your backyard as they arrive and depart from the International Space Station. We caught sight of Progress M-20M just last night, passing very near the waxing crescent Moon. Progress was about magnitude +1 when directly overhead, and was about 9 minutes ahead of the International Space Station. We’ve seen the Dragon, HTV, ATV spacecraft, as well as the U.S. Space Shuttle shortly after undocking from the International Space Station when it was in service. In fact, there’s a series of good passes of the ISS at dusk over the next few evenings for the southeastern United States, including a pass at ~6:58 PM EST tonight. Progress M-20M should be about 20 minutes ahead of the station at this point, assuming, of course, it hasn’t maneuvered in its orbit as a part of ongoing thruster control experiments.

We’ll be checking those final orbital corrections just prior to the pass tonight, as well as tracking the launch and docking of Progress M-22M. Follow us on Twitter (@Astroguyz) for further updates.

Be sure to catch all the action at Baikonur and in low Earth orbit today, both online and overhead!

‘Wobbly’ Alien Planet Has Weird Seasons And Orbits Two Stars

We’re lucky to live on a planet where it’s predictably warmer in the summer and colder in the winter in many regions, at least within a certain range. On Kepler-413b, it’s a world where you’d have to check the forecast more frequently, because its axis swings by a wild 30 degrees every 11 years. On Earth, by comparison, it takes 26,000 years to tilt by a somewhat lesser amount (23.5 degrees).

The exoplanet, which is 2,300 light-years away in the constellation Cygnus, orbits two dwarf stars — an orange one and a red one — every 66 days. While it would be fun to imagine a weather forecast on this planet, in reality it’s likely too hot for life (it’s close to its parent stars) and also huge, at 65 Earth-masses or a “super-Neptune.”

What’s even weirder is how hard it was to characterize the planet. Normally, astronomers spot these worlds either by watching them go across the face of their parent star(s), or by the gravitational wobbles they induce in those stars. The orbit, however, is tilted 2.5 degrees to the stars, which makes the transits far more unpredictable. It took several years of Kepler space telescope data to find a pattern.

“What we see in the Kepler data over 1,500 days is three transits in the first 180 days (one transit every 66 days), then we had 800 days with no transits at all,” stated Veselin Kostov, the principal investigator on the observation. “After that, we saw five more transits in a row,” added Kostov, who works both with the  the Space Telescope Science Institute and  Johns Hopkins University  in Baltimore, Md.

It will be an astounding six years until the next transit happens in 2020, partly because of that wobble and partly because the stars have small diameters and aren’t exactly “edge-on” to our view from Earth. As for why this planet is behaving the way it does, no one is sure. Maybe other planets are messing with the orbit, or a third star is doing the same thing.

The next major question, the astronomers added, is if there are other planets out there like this that we just can’t see because of the gap between transit periods.

You can read more about this finding in The Astrophysical Journal (a Jan. 29 publication that doesn’t appear to be on the website yet) or in preprint version on Arxiv.
