Another wonderful Virtual Star Party, this time with 6 astronomers broadcasting their view of the night sky live. We had amazing views of Saturn, the Ring Nebula, M27, and M17 the Swan Nebula (also known as the Lobster or Horseshoe Nebula). We also caught great views of NGC-896, NGC-869, and the M56 Cluster. Then we got some beautiful views of the Veil Nebula and discussed the benefits of image-stabilized binoculars.
This was also the first time were joined by Scott Ferguson, who delighted us with his dark sky views from the west coast of Florida. His views of the Pelican Nebula (NGC-6996) were gorgeous and unique. Continue reading “Virtual Star Party – October 6, 2013”
Photo taken by ESA astronaut Luca Parmitano on Sept. 5, 2013 (ESA/NASA)
Italian astronaut Luca Parmitano shares a lot of fantastic photos taken from his privileged position 260 miles up aboard the Space Station, orbiting the planet 16 times a day. This is his latest, a stunning view of nighttime city lights spread out beneath a glowing dome of ghostly airglow and shimmering aurorae, with a backdrop of brightly shining stars. The dark silhouette of a solar array is in the foreground at right.
And in case you were wondering, yes, astronauts certainly can see stars while in space. A lot of them, in fact. (Except up there, they don’t twinkle… but they’re no less beautiful!)
“Every time we look into the sky and we admire the same stars, we share the same experience with all those who still know how to dream.”
– Luca Parmitano
Luca Parmitano is the first of ESA’s new generation of astronauts to fly into space. The current mission, Volare, is ESA’s fifth long-duration Space Station mission. During his six-month-long stay aboard the ISS, Luca has been conducting research for ESA and international partners as well as taken many photographs of our planet, sharing them on Twitter, Flickr, and the Volare mission blog.

Update Oct 6: LADEE fired its main engine this morning (Oct. 6) at 6:57 a.m. EDT and successfully achieved lunar orbit. Headline/story revised.
NASA’s trailblazing LADEE lunar spacecraft is set to ignite its main engine and enter lunar orbit on Sunday morning, Oct. 6 – if all goes well – following the spectacular Sept. 6 night launch from NASA’s Virginia spaceport.
And in a happenstance no one could have foreseen, the critical engine firing comes smack in the midst of the political chaos reigning in Washington D.C. that has shut down the US government, furloughed 97% of NASA’s employees, and temporarily threatened the upcoming launch of NASA’s next mission to Mars – the MAVEN orbiter.
But there will be virtually a complete news blackout and little public information released due to the legal requirements of the shutdown.
NASA websites, which are amongst the most heavily trafficked, as well as NASA TV have been shuttered during the shutdown and the press office is likewise furloughed.
So it was do or die for LADEE with the four minute long braking thruster firing set to start on Oct. 6 at 6:57 a.m. EDT (10:57 UTC), so that the couch sized spacecraft is captured by the Moon’s gravity.
Fortunately, LADEE was deemed “essential” and a small team of engineers is working right now at mission control at NASA’s Ames Research Center in California.
If the had burn failed, LADEE will swing by the moon with no hope of returning. And this is being accomplished with a skeleton crew thanks to the government shutdown.
Here’s a video animation of orbital capture at the moon:
Video caption: This video shows the LADEE lunar orbit capture scheduled to take place at 10:57 UTC on 6 Oct. 2013. The main view is an Earth centered perspective showing the effect of the Moon’s gravity on the orbit and then how a Lunar orbit looks from the Earth. The inset view shows the same trajectory from the perspective of the Moon.
Dubbed LOI-1 (Lunar Orbit Insertion burn 1),it is designed to begin with LADEE’s arrival at the Moon after three and a half orbits of the Earth. It will change the spacecrafts velocity by 329.8 meters/sec.
LOI-1 is the first of three main engine maneuvers and will place LADEE into a 24 hour retrograde orbit, with a periselene altitude of 590 km (369 mi).
LOI-2 follows on Oct. 9 to place LADEE into a 4 hour orbit with a 250 km (156 mi) periselene altitude.
Finally LOI-3 on Oct. 12 places LADEE into a roughly circular 250 km (156 mi) orbit that initiates a 30 day commissioning phase as well as experiments using the on-board Lunar Laser Communications Experiment (LLCD) before the start of the missions science phase.
LADEE thundered to space atop the maiden launch of the five stage Minotaur V rocket on Sept. 6, blazing a spectacular trail to orbit from a beachside launch pad at NASA’s Wallops Flight Facility in Virginia.

The blastoff was easily visible to tens of millions of thrilled spectators up and down the eastern seaboard stretching from Maine to the Carolinas as a result of crystal clear skies and the night time liftoff.
The LADEE liftoff at 11:27 p.m. EDT marked the first space probe of any kind ever launched beyond Earth orbit from NASA Wallops, as well as being the first planetary science mission ever launched from Wallops.

Eventually the spacecraft will fly in a very low equatorial science orbit of about 50 kilometers (31 mi) altitude above the moon that will require considerable fuel to maintain. The science mission duration is approximately 100 days, limited by the amount of maneuvering fuel.
The 844 pound (383 kg) robot explorer was assembled at NASA’s Ames Research Center, Moffett Field, Calif., and is a cooperative project with NASA Goddard Spaceflight Center in Maryland.
It is equipped with a trio of science instruments whose purpose is to collect data that will inform scientists in unprecedented detail about the ultra thin lunar atmosphere, environmental influences on lunar dust and conditions near the surface.
The goal of the $280 Million mission is to gain a thorough understanding of long-standing unknowns about the tenuous atmosphere, dust and surface interactions that will help scientists understand other planetary bodies as well.
The probe is built on a revolutionary ‘modular common spacecraft bus’, or body, that could dramatically cut the cost of exploring space and also be utilized on space probes to explore a wide variety of inviting targets in the solar system.
“LADEE is the first in a new class of interplanetary exploration missions,” NASA Ames Director Pete Worden told Universe Today in an interview. “It will study the pristine moon to study significant questions.”
“This is probably our last best chance to study the pristine Moon before there is a lot of human activity there changing things.”

While some of you will no doubt be heading to the theaters to see the new release of “Gravity,” for those that want to stay in for the weekend, here’s the perfect short film. The National Radio Astronomy Observatory (NRAO) has released a new 24-minute film about the recently renovated Karl G. Jansky Very Large Array (VLA) radio telescope. The film is narrated by Academy Award-winning actress Jodie Foster, star of the 1997 Warner Brothers film, “Contact,” which was filmed in part at the VLA.
“In ‘Contact,’ I played the role of an astronomer using the VLA,” Foster said. “In narrating this new film for the VLA Visitor Center, I have the privilege of introducing tomorrow’s scientists, technicians, and engineers to the amazing complexities of this great telescope, and to the wonders of the universe that it reveals.”
Titled “Beyond the Visible,” the film tells the behind-the-scenes story of the operation and scientific achievements of the VLA, which has been at the forefront of astrophysical research since its dedication in 1980. Spectacular ground and aerial footage of the iconic radio telescope is augmented by first-person interviews with staffers who keep the telescope working and scientists who use it to discover exciting new facts about the universe. The film also depicts many of the technical tasks needed to keep the array functioning at the forefront of science.
“Since the last film for the Visitor Center was produced in 2002, we’ve completed a massive technological upgrade that turned the VLA into a completely new and vastly more powerful tool for cutting-edge science,” said Dale Frail, NRAO’s Director for New Mexico Operations. “It was time to update the story we tell our visitors,” he added.
The film replaces an earlier video that ran at the VLA Visitor Center auditorium, which is visited by some 20,000 people annually. You can’t currently go to the Visitor Center to see the new film at the moment, however, because of the US federal government shutdown. So, watch it here. Hopefully the shutdown will be resolved soon so that people can resume their visits to the VLA.

Call it Space Survivor. Thirteen years after that now-classic desert island nightmare premiered on NBC, the executive producer behind Survivor is planning to host another reality competition that will land the winner a rocket trip to space.
We don’t know yet what feats of strength, endurance, intelligence or teamwork (or is that backstabbing?) will be needed to score a trip with Virgin Galactic. A press release simply promises a “groundbreaking, elimination competition series where everyday people compete for the ultimate prize”, but we sure hope a lot of the individual contests are space-related.
“For the past 10 years I have relentlessly pursued my dream of using a TV show to give an everyday person the chance to experience the black sky of space and look down upon mother Earth,” stated executive producer Mark Burnett, who heads One Three Media. Burnett seems to have chosen the Richard Branson-backed SpaceShipTwo (now doing powered flight tests) as the best chance of getting competitors into space in the near future.
Sir Richard Branson hugs designer Burt Rutan as they are surrounded by employees of Virgin Galactic, The SpaceShip Company and Scaled Composites watch as Virgin Galactic’s SpaceShip2 streaks across the sky under rocket power, its first ever since the program began in 2005. Burt’s wife Tonya Rutan is at right taking their photo. The spacecraft was dropped from its “mothership”, WhiteKnight2 over the Mojave, CA area, April 29, 2013 at high altitude before firing its hybrid power motor. Virgin Galactic hopes to become the first commercial space venture to bring multiple passengers into space on a regular basis.
“Last year, I spent time in New Mexico at the state-of-the-art facility and last week [I] spent time in the Mojave desert with Sir Richard and his impressive team. We got to see the spaceship up close and hear of Sir Richard’s incredible vision of how Virgin Galactic is the future of private space travel. I am thrilled to be part of a series that will give the everyday person a chance to see space, and that NBC has come on board too so that viewers at home will have a first-class seat.”
Virgin says its first spaceflight with SpaceShipTwo will be in 2014, and soon after it will open the manifest to the more than 600 folks who have purchased tickets.
As for when we’ll expect to see Space Race hit the airwaves, let’s just caution that this is just an agreement so far and nothing firm has been decided.
Recall that in 2000, Burnett announced another deal with NBC to host a space reality show (Destination Mir), with the winner visiting the Russian space station Mir. That idea fell apart when the cash-strapped Russian Federal Space Agency elected to deorbit the aging station in 2001 and focus its resources on the International Space Station.
Burnett subsequently proposed another show that would have brought ‘N Sync guitarist Lance Bass to the International Space Station, but that idea never got off the ground.
Screengrab from the WildCat video from Boston Dynamics.
This is both wonderful and terrifying. A DARPA-funded four-legged robot named WildCat is being developed by a company called Boston Dynamics (tagline of “Changing Your Idea of What Robots Can Do”). They’ve previously developed a humanoid capable of walking across multiple terrains called Atlas, and the scarily-fast Cheetah which set a new land-speed record for legged robots. But the WildCat is a brand new robot created to run fast on all types of terrain, and so far its top speed has been about 16 mph on flat terrain using both bounding and galloping gaits.
The video, released yesterday, shows WildCat’s best performance so far. Don’t let the sound fool you — yes, it does sound like a weed-whacker. But as soon as it raises up off its haunches, you know you’re doomed.
I’ve been trying to figure out what sci-fi equivalent might describe it best: the Terminator’s pet? A lethal, non-fuzzy Daggit from Battlestar Galactica? An AT-AT Walker on speed?
One of the ‘hot’ memes these days are collections of sayings by various groups or persons, classified under the “S*** [insert name] Says” genre of videos, articles and websites. A new site making the rounds among the space community is “S*** Elon Says” which includes an assemblage of over 40 actual quotes from SpaceX and Tesla founder Elon Musk. Besides listing some of the most awesome, peculiar and downright futuristic quotes from Musk, this site is also one of the most thoroughly researched in this type of meme, as each quote links to transcripts of press conferences, news shows and conference panels where Musk actually said these things.

The organizers of the World Space Week Association are working to create an “Earth Master Sample”, and they want your help. Anyone worldwide can send the association a fist-sized rock from their locale.
Next will come the interplanetary recipe magic: Once the samples arrive, a tiny bit of each rock will be procured and ground into a powder. The powder will be mixed together, with a dash of Mars meteorite added in. Next, a crystal company (Swarovski) will melt down the combination into 100 crystals.
These crystals will be shown off at Yuri’s Night celebrations on April 12, 2014; the event commemorates the first human spaceflight by Yuri Gagarin, which took place on that day in 1961. More importantly, the organizers said, the crystals will stand as a symbol of the importance of doing “planetary analog” research on Earth to better understand the conditions on other planets.
Earth and Mars are compared in size as they look today.
“By participating in the Earth Master Sample campaign, people can show their support for analog exploration and their aspiration to see Mars exploration continue through sample return missions and, eventually, human expeditions,” stated Remco Timmermans, the association’s executive director.
Here are the instructions (reproduced below verbatim from the association):
Take a picture of the sample site and a scale (e.g. classmate, family member etc.) from at least 10m distance
Take a close-up picture with a scale (e.g. hammer, pen, etc)
Note your geographical location (e.g. 31°22.363 N 4°4.357 W)
Take a fist-sized rock sample. (No soil samples, no sand please).
Put the sample into a clean plastic bag. IMPORTANT: Label the sampling bag with: date (DD/MM/YY) + Time (HH:MM) + geographical coordinates. (e.g. 17AUG13 17:22, 47.234 N / 11.234 E)
Send an email to [email protected] listing the geographical location, the two pictures and the details of a contact person.
Mail the rock-sample to: Austrian Space Forum / Earth Master Sample Project, Sillufer 3a, 6020 Innsbruck, AUSTRIA
Deadline: 15. November 2013 (for arrival of rocks at the Austrian Space Forum)
This year, World Space Week runs from Oct. 4 to Oct. 10, 2013. The association will hold events at the Austrian Space Forum in Innsbruck, Austria. Here’s more information on their activities.

Fomalhaut is a really cool place to study. The naked-eye star (the brightest star in the constellation Piscis Austrinus) has a planet, Fomalhaut b, that once appeared dead but rose again in science circles. It is the site of a comet massacre. Now it’s getting even more interesting: Scientists have believed for years that Fomalhaut is a double star, but a new paper proposes that it is actually a triplet.
“I noticed this third star a couple of years ago when I was plotting the motions of stars in the vicinity of Fomalhaut for another study,” stated Eric Mamajek, associate professor of physics and astronomy at the University of Rochester. The third star is known as LP876-10 or Fomalhaut C.
“However, I needed to collect more data and gather a team of co-authors with different observations to test whether the star’s properties are consistent with being a third member of the Fomalhaut system.”
That opportunity came when Mamajek was in Chile and by chance, talking with Georgia State University’s Todd Henry, who is the director of the Research Consortium on Nearby Stars. A student (who has now graduated), Jennifer Bartlett at the University of Virginia, was working on a study of potential nearby stars for her Ph.D. thesis, which included the star that Mamajek was curious about.

The team plotted the star’s movements and spectroscopy (to see its temperature and radial velocity) and concluded the speed and distance of the star matched that of the Fomalhaut system.
LP876-10/Fomalhaut C is a red dwarf that appears the distance of 11 full moons apart from Fomalhaut in the night sky. It seems counterintuitive to believe they are close together, but the team reminds us that Fomalhaut is very close to us as stars go: 25 light-years away.
“That they appear so far apart could explain why the connection between LP 876-10 and Fomalhaut had been previously missed,” the team stated.

Following a three day period of complete work stoppage due to the US Government Shutdown, technicians late today (Oct. 3) resumed critical launch preparations for NASA’s next mission to Mars, the MAVEN orbiter. And it’s not a moment too soon, because the consequences of a continued suspension would have been absolutely dire for the entire future of Mars exploration!
“We have already restarted spacecraft processing at the Kennedy Space Center (KSC) today,” Prof. Bruce Jakosky, MAVEN’s chief scientist told Universe Today in a special new mission update today.
Today, Oct 3, top NASA managers have “determined that MAVEN meets the requirements allowing an emergency exception relative to the Anti-Deficiency Act,” Jakosky told me.
MAVEN had been scheduled to blast off for the Red Planet on Nov.18 atop an Atlas V rocket from the Florida Space Coast until those plans were derailed by the start of the government shutdown that began at midnight, Tuesday (Oct. 1) due to senseless and endless political gridlock in Washington, DC.
The upcoming Nov. 18 blastoff of NASA’s new MAVEN Mars orbiter was threatened by the US Federal Government shutdown when all launch processing work ceased on Oct. 1. Spacecraft preps had now resumed on Oct. 3. MAVEN was unveiled to the media, including Universe Today, inside the cleanroom at the Kennedy Space Center on Sept. 27, 2013.

About 97% of NASA’s workforce had been immediately furloughed on Oct. 1 and ordered not to go to work – along with some 800,000 other Federal employees – when their work was deemed “non-essential” despite maintaining spacecraft valued at tens of billions of dollars.
This left only skeleton crews manning Mission Control’s for dozens and dozens of ongoing space missions and the International Space Station (ISS)
Despite the work hiatus, the team is still hoping to achieve an on time launch or soon thereafter.
“We are working toward being ready to launch on Nov. 18,” Jakosky told me, as MAVEN’s principal Investigator of the University of Colorado at Boulder.
“We will continue to work over the next couple of days to identify any changes in our schedule or plans that are necessary to stay on track.”
How realistic is the original Nov. 18 launch date, I asked?
“We think it’s very feasible,” Jakosky responded.
“With our having been shut down for only a few days, we should be back on track toward this date quickly.”
The processing team at KSC lost three days of the nine days of margin in the schedule.

Where does the team pick up with work?
“With the facility now back up and running, we more or less pick up right where we left off,” Jakosky explained
“We are reworking the schedule to make sure our activities are integrated together and that people don’t have to be in two places at once.”

The nominal launch window for NASA’s $650 Million MAVEN (Mars Atmosphere and Volatile EvolutioN Mission) mission to study the Red Planet’s atmosphere only extends about three weeks until Dec. 7.
And he said the team will do whatever necessary, including overtime, to launch MAVEN to the Red Planet by Dec. 7.
“The team is committed to getting to the launch pad at this opportunity, and is willing to work double shifts and seven days a week if necessary. That plus the existing margin gives us some flexibility. “
Interestingly, the ‘’emergency exemption” was granted because of MAVEN’s additional secondary role as a communications relay for NASA’s intrepid pair of surface rovers – Curiosity and Opportunity – and not because of its primary science mission.
“MAVEN is required as a communications relay in order to be assured of continued communications with the Curiosity and Opportunity rovers,” Jakosky explained.

Although NASA has two functioning orbiters circling the Red Planet at this moment, they are getting old, are far beyond their original design lifetimes and suffer occasional glitches. And there is no guarantee of continued operation.
“The rovers are presently supported by Mars Odyssey launched in 2001 and Mars Reconnaissance Orbiter launched in 2005.”
“Launching MAVEN in 2013 protects the existing assets that are at Mars today,” Jakosky told me.
If Mars Odyssey and/or Mars Reconnaissance Orbiter were to fail, then the rovers mission operations would be severely curtailed and could even be terminated prematurely – in a worst case scenario.
And without MAVEN, there would be no point in launching NASA’s planned 2020 rover since there would be no way to transmit the science data back to Earth.
“There is no NASA relay orbiter at Mars planned post-MAVEN,” Jakosky noted.
If MAVEN has to launch later in December 2013 or is forced to be postponed to the next launch window opportunity in 2016, both the communications relay capability and the missions atmospheric science objectives would have been very badly impacted.
“A delay in the launch date by more than a week past the end of the nominal launch period, or a delay of launch to 2016, would require additional fuel to get into orbit.”
“This would have precluded having sufficient fuel for MAVEN to carry out its science mission and to operate as a relay for any significant time,” Jakosky elaborated.
“Our nominal launch period runs from 18 November through 7 December, and we can launch as late as about 15 December without a significant impact on our combined science and relay activities.”
From a purely science standpoint, 2013 is the best time to launch MAVEN to accomplish its science objectives.
“Although the exception for MAVEN is not being done for science reasons, the science of MAVEN clearly will benefit from this action.”
“Launching in 2013 allows us to observe at a good time in the eleven-year solar cycle.”
“MAVENS’s goal is determining the composition of the ancient Martian atmosphere and when it was lost, where did all the water go and how and when was it lost,” said Jakosky.
Stay tuned here for continuing MAVEN and government shutdown updates.
And watch for my articles about critical operations related to LADEE on Oct 6 and JUNO on Oct. 9. The government shutdown negatively impacts these missions and others as well.
