Virgin Galactic Ticket To Space Promised In New Reality Show Deal

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.

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.

This Video of a Cyborg Quadriped Will Have You Gasping in Terror

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?

At any rate … Yikes!

Yes, Elon Musk Really Does Say All This, Um … Awesome Stuff

Elon Musk via 's***elonsays.com'

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.

Enjoy a little Friday diversion to read some of the um, awesome stuff Elon says.

Here’s Your Chance To Help Blend Earth And Mars Rocks

The official poster of the World Space Week Association 2013 campaign. Credit: World Space Week Association

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.

Are Earthlings really Martians ? Did life arise on Mars first and then journey on meteors to our planet and populate Earth billions of years ago?  Earth and Mars are compared in size as they look today.
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):

  1. Take a picture of the sample site and a scale (e.g. classmate, family member etc.) from at least 10m distance
  2. Take a close-up picture with a scale (e.g. hammer, pen, etc)
  3. Note your geographical location (e.g. 31°22.363 N 4°4.357 W)
  4. Take a fist-sized rock sample. (No soil samples, no sand please).
  5. 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)
  6. Send an email to [email protected] listing the geographical location, the two pictures and the details of a contact person.
  7. Mail the rock-sample to: Austrian Space Forum / Earth Master Sample Project, Sillufer 3a, 6020 Innsbruck, AUSTRIA
  8. 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.

Double Star Fomalhaut May Actually Be A Triplet!

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.

The paper is available on the preprint website Arxiv and has been accepted for publication in the Astronomical Journal.

NASA’s MAVEN Mars orbiter granted ‘Emergency Exemption’ to Resume Processing during Government Shutdown

Story updated[/caption]

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.

Astronomers Without Borders – those great folks who do science outreach around the world – is getting ready for the next solar eclipse, which takes place on November 3, 2013. A partial eclipse will be visible across a wide swath of Africa and AWB needs your help so that tens of thousands of eclipse glasses can be sent to schools in Africa in time for the eclipse.

“We’re working with the IAU’s Office of Astronomy for Development who has contacts working with schools and able to distribute the glasses to them,” Mike Simmons, who leads AWB, told Universe Today via email. “The opportunity for this came up late so we’re working very hard to make it happen in the short time we have left.”

Simmons added that this is a rare opportunity to expose students to science in a region where science resources are often non-existent, and AWB will be giving the glasses to schools at no charge.

But they need donations to make that happen. Click here to find out how to help.

The AWB website says that schools have been identified and vetted by partner organizations in each country in Africa, and distribution networks have been verified. Every donated pair of eclipse glasses WILL reach a student for use for the eclipse. The International Astronomical Union’s Office of Astronomy for Development, which is based in Cape Town, South Africa, is providing invaluable support and assistance through their many contacts across Africa.

This program depends entirely on donations.

“There’s no question we can get all the donations that are needed as long as we get the word out in time,” Simmons said.

Please consider donating, as AWB does amazing work.

“We do probably a half-million dollars in programs each year based on the hard work of passionate amateur astronomers and educators around the world,” Simmons said, “all on way less than $25,000 a year.”

This is a great astronomy outreach organization that really could use financial help of any kind, so feel free to donate to their general cause, as well.

You can also purchase eclipse glasses for your own use from AWB here.

What are the Phases of the Moon?

What are the Phases of the Moon?

Everyone knows that the Moon goes through phases, but let’s talk about why it does. It comes down to illumination, which in this case, all originates from our nearby star.

Our Moon orbits around our planet, and this Earth-Moon system orbits around the Sun.

Even though we only see light on part of the Moon, from the perspective of the Sun, half of it is always illuminated.

Stuck here on Earth, we see the Moon in various phases of illumination as it completes a 27.3 day orbit around the Earth.

As The Moon travels around us we see it pass through its phases. It goes from New Moon, to Full Moon and back to new Moon again.

Crescent Moons are when it’s less than half illuminated, and gibbous when it’s more than half.

“Waxing” means that the Moon becomes more illuminated night-by-night, and the term “waning” means that it’s getting less illuminated each night.

  • New Moon – When the illuminated side of the Moon is away from the Earth. The Moon and the Sun are lined up on the same side of the Earth, so we can only see the shadowed side. This is also the time that you can experience solar eclipses, when the Moon passes directly in front of the Sun and casts a shadow onto the surface of the Earth. During a new moon, we can also see the reflected light from the Earth, since no sunlight is falling on the Moon – this is known as earthshine.
  • Crescent – The crescent moon is the first sliver of the Moon that we can see. From the northern hemisphere, the crescent moon has the illuminated edge of the Moon on the right. This situation is reversed for the southern hemisphere.
  • First Quarter – Although it’s called a quarter moon, we actually see this phase when the Moon is half illuminated. This means that the Sun and the Moon make a 90-degree angle compared to the Earth.
  • Waxing Gibbous – This phase of the Moon occurs when the Moon is more illuminated that half, but it’s not yet a full Moon.
  • Full Moon – This is the phase when the Moon is brightest in the sky. From our perspective here on Earth, the Moon is fully illuminated by the light of the Sun. This is also the time of the lunar month when you can see lunar eclipses – these occur when the Moon passes through the shadow of the Earth.
  • Waning Gibbous – In this lunar phase, the Moon is less than fully illuminated, but more than half.
  • Last Quarter – At this point of the lunar cycle, the Moon has reached half illumination. Now it’s the left-hand side of the Moon that’s illuminated, and the right-hand side in darkness (from a northern hemisphere perspective).
  • Crescent – This is the final sliver of illuminated moon we can see before the Moon goes into darkness again.

If you ever get the chance to travel to the other hemisphere, you’ll immediately notice how unfamiliar the Moon behaves – it’s upside down.

If you live in the Northern Hemisphere, after a New Moon the crescent begins on the right-side. But if you’re in the Southern Hemisphere, it’s reversed, with the illumination starting on the left side.

Weird.

The alignment of the Sun, Earth and Moon can lead to some fantastic astronomical events.

One event occurs when the Moon is full, and it passes through the Earth’s shadow. Or as you probably know it, a lunar eclipse. This causes the Moon to grow dark and then turn an eerie red color.

When the Moon is new, it can pass in between the Earth and the Sun, casting its shadow down on our planet. As you know, a solar eclipse.

You’d think we would see a solar and lunar eclipse every month, but we don’t because the Moon’s orbit is inclined relative to the Sun.

Most months, the Moon is either above or below the Sun in the sky, so they just don’t line up perfectly.

One more thing, you might not know that Venus also goes through phases. When the planet is on the other side of the Sun from us, we see it as a nearly complete disk. But when Venus is on our side, just about to pass into the glow of the Sun, it’s a thin crescent, just like how we see the Moon.

I hope this gives you a better understanding of why the Moon goes through its phases every month, and the interesting relationship between the Earth, the Sun, and the Moon.

Keck Spots A Galaxy Fueled With Ancient Gas

“Primordial hydrogen” sounds like a great name for a band. It’s also a great thing to find when you’re looking at a galaxy. This ancient gas is a leftover of the Big Bang, and astronomers discovered it in a faraway star-forming galaxy that was created when the universe was young.

A continuous stream of gas was likely responsible for a cornucopia of star formation that took place about 10 billion years ago, when galaxies were churning out starbirths at a furious rate.

The astronomers spotted the gas by using a quasar that lit up the fuel from behind. Quasars a handy tool to use if you want to illuminate something, because even though quasars don’t live for very long in cosmic terms — they occur when matter falls into a ginormous black hole — they are extremely bright. Since the gas absorbs the light at certain frequencies, the absorption lines that show up in spectrometers reveal information about the composition, temperature and density of the gas.

“This is not the first time astronomers have found a galaxy with nearby gas, revealed by a quasar. But it is the first time that everything fits together,” stated Neil Crighton, who is with the Max Planck Institute for Astronomy and Swinburne University and led the research. His team found the galaxy using the Keck I telescope in Hawaii.

“The galaxy is vigorously forming stars,” added Crighton, “and the gas properties clearly show that this is pristine material, left over from the early universe shortly after the Big Bang.”

Q1442-MD50 (as the galaxy is called) is 11 billion light years away from us — pretty close to the start of the universe about 13.8 billion years ago. The quasar that lit it up is called QSO J1444535+291905.

“Since this discovery is the result of a systematic search, we can now deduce that such cold flows are quite common,” stated Joseph Hennawi, the leader of the ENIGMA research group at the Max Planck Institute for Astronomy. “We only had to search 12 quasar-galaxy pairs to discover this example. This rate is in rough agreement with the predictions of supercomputer simulations, which provides a vote of confidence for our current theories of how galaxies formed.”

Best Ever Astronaut ‘Selfies’

“Talk about a selfie!” wrote former astronaut Clay Anderson on Twitter yesterday (Oct. 1). He posted that comment along with a favorite photo from Expedition 15, when he was standing in restraints on the robotic Canadarm2. Off in the distance, he saw his shadow against the solar array panels of a Soyuz spacecraft.

That got us thinking — what are the best astronaut selfies? Below are some of our favourites (some intentional, some not) from over the years. Any that we have missed? Let us know in the comments!
