NASA Targeting Earth Observing Satellites and ISS Sensors to Aid Missing Malaysian Airline Search

NASA has actively joined the hunt for the missing Malaysian Airline flight MH-370 that mysteriously disappeared without a trace more than two weeks ago on March 8, 2014.

Sensors aboard at least two of NASA’s unmanned Earth orbiting global observation satellites as well as others flying on the manned International Space Station (ISS) are looking for signs of the jetliner that could aid the investigators from a multitude of nations and provide some small measure of comfort to the grieving families and loved ones of the passengers aboard.

“Obviously NASA isn’t a lead agency in this effort. But we’re trying to support the search, if possible,” Allard Beutel, NASA Headquarters, Office of Communications director, told Universe Today this evening.

NASA’s airplane search assistance comes in two forms; mining existing space satellite observing data and retargeting space based assets for new data gathering since the incident.

The Malaysian Airline Boeing 777-2H6ER jetliner went missing on March 8 while cruising en route from Kuala Lampur, Malaysia to Beijing, China. See cockpit photo below.

Accurate facts on why MH-370 vanished with 239 passengers aboard have sadly been few and far between.

Last week, the search area shifted to a wide swath in the southern Indian Ocean when potential aircraft debris was spotted in a new series of separate satellite images from Australia and China government officials.

A prior set of official Chinese government satellite images at a different location yielded absolutely nothing.

The area is now focused 2,500 km (1,600 mi) south west of Perth, a city on the western coast of Australia.

NASA’s search support was triggered upon activation of the International Charter on Space and Major Disasters.

Available data from NASA’s Terra and Aqua satellites has already been transmitted to the U.S. Geological Survey and new data are now being collected in the search area.

“In response to activation of the International Charter on Space and Major Disasters last week regarding the missing Malaysia Airlines jetliner, NASA sent relevant space-based data to the U.S. Geological Survey’s Earth Resources Observations and Science Hazard Data Distribution System that facilitates the distribution of data for Charter activations,” according to a NASA statement.

And it’s important to note that NASA satellites and space-based cameras are designed for long-term scientific data gathering and Earth observation.

“They’re really not meant to look for a missing aircraft,” Beutel stated.

“The archive of global Earth-observing satellite data is being mined for relevant images. These include broad-area views from the MODIS [instrument] on NASA’s Terra and Aqua satellites,” Beutel informed me.

The next step was to retarget both satellites and another high resolution camera aboard the ISS.

“In addition, two NASA high-resolution assets have been targeted to take images of designated search areas: the Earth Observing-1 satellite and the ISERV camera on the International Space Station,” Beutel explained.

Aqua and Terra were already gathering new observations with the MODIS instrument in the search area off Australia last week. MODIS measures changes in Earth’s cloud cover.

Here are the satellite observation times and capabilities:

• MODIS on the Aqua satellite observed at about 1:30 p.m. local time as it passes overhead from pole-to-pole
• MODIS on the Terra satellite observed at about 10:30 a.m. local time
• The width (field of view) of a MODIS observation is 2,300 kilometers
• One pixel of a MODIS image – the limit of how small a feature it can see – is about 1 kilometer.

A new set of high resolution Earth imaging cameras are being sent to the ISS and are loaded aboard the SpaceX CRS-3 Dragon resupply capsule now slated for blastoff on March 30.

The newly launched NASA/JAXA GPM precipitation monitoring satellite which will cover this ocean area in the future is still in the midst of science instrument checkout.

Ships and planes from at least 26 countries have been being dispatched to the new based on the new satellite imagery to search for debris and the black boxes recording all the critical engineering data and cockpit voices of the pilot and copilot and aid investigators as to what happened.

No one knows at this time why the Malaysia Airlines flight mysteriously disappeared.

Sirius, UFO trickster extraordinaire

Pilot Kenneth Arnold with an illustration of a UFO he saw in 1947. The modern run of UFO sightings began when Arnold reported seeing nine objects flying in a V-formation over Mt. Ranier in Washington. Click for more on the story.

Scintillating Sirius is sometimes mistaken for a UFO

I’ve never seen a UFO that stayed a UFO. I remember certain moving lights as a kid but they turned out to be airplanes or geese aglow with light pollution. And who hasn’t been tricked into thinking they’ve discovered the next Milky Way supernova only to realize it was a distant aircraft in your line of sight?

For all the hours of dark sky time amateur astronomers accumulate, few of us have seen a UFO. It makes sense. We’re generally familiar with the stars and their movements, where the planets happen to be and the atmosphere’s uncanny ability to distort and parse light into strange and beautiful phenomena. Not that some skywatchers haven’t seen a few things that defy immediate explanation.

While some might say this takes away the magic of the night sky, rendering us blind to the possibility of UFOs, I’d argue the contrary. Knowledge deepens our appreciation of all we see, hear, smell and touch.

Sirius, nicknamed the Dog Star is the brightest star in Canis Major and brightest in the night sky. This map show Sirius about 1/3 of the way up in the southern sky during late twilight this month. Stellarium — Sirius, nicknamed the Dog Star, is the brightest star in Canis Major and brightest in the night sky. This map show Sirius about 1/3 of the way up in the southern sky during late twilight this month. Stellarium

Familiar objects often mistaken for UFOs include bright stars, planets and satellites, but high – if not highest – on the list is Sirius in the constellation Canis Major the Greater Dog.

Sirius has attained UFO status for several good reasons: at magnitude -1.5 it’s the brightest star in the sky, it “moves” both slowly and rapidly and shoots out light of different colors.

Because it’s bright, and for many of us, falls along an easy line of sight on March evenings, we’re bound to notice it. No star sparkles more intensely especially when hovering low in the sky.

For skywatchers at mid-northern latitudes, Sirius is the bright, often flashing star in the southern sky at nightfall. Credit: Bob King

Stars. So big but yet so tiny. Despite their enormous size, distance reduces stars to tiny pinpoints even in the largest telescopes. When a star beam hits our atmosphere, it gets yanked around by parcels of air of varying density, speed and size. Each parcel acts like a individual lens, refracting or bending the star’s light into a tiny image. As the air churns overhead, the positions of all those individual images continually change, zigging the star in random directions. While our eyes aren’t keen enough to distinguish the many tiny images moving to and fro, we sense the starlight’s tortured path as sputtering light or twinkling. All stars flitter around – just ask telescopic observers – but twinkling is most noticeable in bright stars like Vega, Canopus, Rigel and especially Sirius.

Twinkling is caused by moving air pockets in our atmosphere. Twinkling is much stronger and more noticeable near the horizon, because our line of sight passes through a much greater thickness of air. Illustration: Bob King - See more at: http://astrobob.areavoices.com/2011/09/04/why-stars-twinkle-and-sputter-in-color/#sthash.MNP51ROv.dpuf — Twinkling is caused by moving air pockets in our atmosphere. Twinkling is much stronger and more noticeable near the horizon, because our line of sight passes through a much greater thickness of air. Illustration: Bob King

Mind you, it doesn’t necessarily matter how calm it is on the ground. Some 10 miles of relatively thick air between you and Sirius provide plenty of opportunities for fluttering images on many otherwise tranquil nights. Bright planets generally don’t twinkle because they’re close enough to show actual disks. Tiny shifts induced by atmospheric turbulence can bodily move a star with ease, but planets are big enough compared to the size of the air cells to hold their own and beam forth a steady light.

For some, Sirius’ twinkling creates the sense that a star is moving or shooting about, making it that much more mysterious. Superimposed on this apparent rapid movement is the slow westward drift of the stars caused by Earth’s rotation. People have contacted me about brilliant, slow-moving objects, and it’s clear they’ve been watching a star get a free ride from our revolving planet.

The color and brightness of Sirius can change rapidly as it twinkles. I shot these slightly out of focus to spread the color out and show it more clearly. Not only are the hues striking but brightness changes are obvious, too. Photo: Bob King — The color and brightness of Sirius changes rapidly as it twinkles. I shot these individual 1/30″ photos slightly out of focus to spread the color out and show it more clearly. Not only are the hues striking but brightness changes are obvious, too.

So we’ve got brightness and movement going for us – what about color? Colors come from the air, too. Just as white light is composed of a rainbow or spectrum of individual colors from indigo to red, so is starlight. When Sirius is low above the horizon, refraction (bending of light) is strong enough to create images of the star in every color of the rainbow and cast them about in different directions. Split-second variations in air density and flow make for continuous multi-color sparkles.

Sirius’ colors are fairly obvious with the naked eye, but I’ve found binoculars show them even better. By the way, the jerkiness induced in holding binoculars steady adds another motion factor to the UFO equation.

Sirius is hotter, brighter and 1.75 times the size of our own sun. It's located nearby as stars go at a distance of 8.7 light years, the main reason it appears so bright in the sky. Credit: Wikipedia — Sirius is hotter, brighter and 1.75 times the size of our own sun. As stars go, it’s practically in our backyard at just 8.7 light years away – the main reason it appears so bright in the nighttime sky. Credit: Wikipedia

Once, a fellow came to our local planetarium with video he’d taken of a UFO, hoping for help in identifying the object. We watched it change from a star to a bloated disk and back to a star again as the image jumped wildly about in the shaky, hand-held camera. Knowing the date and time of the footage, we instantly knew it was the camera struggling to maintain autofocus on Sirius.

I remember thinking, “wow, we really helped this guy out”, but he was less than pleased. We tried to explain that he was seeing not only the brightest star in the sky but one twice as massive as the sun and nearly twice its size. But facts were of no use. Convinced he had recorded a UFO anyway, he took his video and promptly left!

I’d love to see a real space ship UFO powered by alien biology. Deep down many of us suspect they exist. With 1,779 extra-solar planets confirmed to date, habitats for potential life seem more certain than ever. But what are the odds of little green men dropping by anything soon? Not only are the distances between stars daunting, but intelligent species may have no interest in outer space or leaving the home planet. After all, whales don’t build space ships.

KENNEDY SPACE CENTER, FL – NASA’s Curiosity rover has just pulled into gorgeous terrain chock full of curvy rock outcrops at Kimberley that’s suitable for contact science and drilling action, according to the mission team.

The six wheeled Martian dune buggy drove into the dazzling Kimberley waypoint this week after traversing a swath of otherworldly dune fields since passing through a gateway known as the ‘Dingo Gap’ sand dune some six weeks ago.

The robot’s arm has been deployed to investigate the most scientifically productive spots to touch Kimberley’s textured outcrops for detailed scrutiny.

The science team has been hunting for tasty rock outcrops suitable for the first drilling campaign since she departed the dried out lakebed at Yellowknife Bay in July 2013 and began her epic trek across the floor of Gale Crater towards the base of Mount Sharp.

With each passing Sol, or Martian day, Mount Sharp looms larger and larger and the historical layers with deposits of hydrated minerals potentially indicative of an alien habitable zone come ever clearer into focus.

About a month ago on Feb. 19 (Sol 548), Curiosity couldn’t resist the urge to pause mid dune drive, just like a tourist, and snap fabulous imagery of multiple rows of striated rocks at the Junda outcrop – see our mosaics below.

Junda appeared remarkably similar to Kimberley, about 1 kilometer back.

So after executing a final series of short bumps edging ever closer to the outcrops this week, Curiosity parked at the periphery of Kimberley on Thursday, March 20, Sol 576, and captured breathtaking imagery of the rocky rows dominated by towering Mount Sharp on the distant horizon.

See our photomosaics showing the spectacularly inviting terrain around Kimberley and Junda – above and below by Marco Di Lorenzo and Ken Kremer.

“The images [at Kimberley] show nice outcrops in front of the rover, suitable for contact science,” according to science team member Ken Herkenhoff in a mission update.

This weekend, the state of the art robot is conducting contact science with the cameras and spectrometers on the terminus of the 7 foot long robotic arm and the mast mounted ChemCam laser and high resolution cameras to determine the best spot for drilling and sampling.

The team commanded Curiosity to clean out the arms CHIMRA sample handling mechanism in anticipation of boring into the Martian outcrops and delivering powdery, pulverized samples of cored Martian rocks to the SAM and CheMin miniaturized chemistry labs waiting patiently inside the robots belly to eat something exciting from the Red Planet.

“The arm will be deployed to “thwack” and vibrate CHIMRA to clean out any remnants of the “John Klein” [drilling] sample, followed by Mastcam and RMI imaging of the CHIMRA sieve,” says Herkenhoff.

Scientists directed Curiosity on a pinpoint drive to Kimberly after their interest was piqued by orbital images taken by the powerful telescopic camera on NASA’s Mars Reconnaissance Orbiter (MRO) circling overhead.

“At Kimberly, we see three terrain types exposed and a relatively dust-free surface,” said science team collaborator Katie Stack of the California Institute of Technology, Pasadena.

The missions science focus has shifted to “search for that subset of habitable environments which also preserves organic carbon,” says Curiosity Principal Investigator John Grotzinger, of the California Institute of Technology in Pasadena.

Organic molecules are the building blocks of life as we know it.

The sedimentary foothills of Mount Sharp, which reaches 3.4 miles (5.5 km) into the Martian sky, is the 1 ton robots ultimate destination inside Gale Crater because it holds caches of water altered minerals. Such minerals could possibly indicate locations that sustained potential Martian life forms, past or present, if they ever existed.

Curiosity discovered a habitable zone at Yellowknife via two drilling operations at the John Klein and Cumberland outcrops and thereby accomplished the primary goal of the mission.

To date Curiosity’s odometer stands at 6.2 kilometers. She has taken over 132,000 images.

The robot has somewhat over another 4 kilometers to go to reach the base of Mount Sharp.

She may arrive at the lower reaches of Mount Sharp sometime in mid 2014, but must first pass through a potentially treacherous dune field.

Meanwhile, NASA’s sister Opportunity rover is exploring clay mineral outcrops by the summit of Solander Point on the opposite side of Mars at the start of her 2nd Decade investigating the Red Planet’s mysteries.

A pair of new orbiters are streaking to the Red Planet to fortify Earth’s invasion fleet- NASA’s MAVEN and India’s MOM.

Check Out These Online Astronomy Classes and Contests

Here are a few upcoming and ongoing astronomy classes and photography contests that our readers may be interested in.

Once a year, the One-Minute Astronomer — aka Brian Ventrudo — offers a detailed course called “The Art of Stargazing,” and you need to act fast on this one, as the final signup date is March 24, 2014. This 12-month course breaks down everything you need to know about stargazing into bite-sized pieces… detailed sky tours, choosing and using the best binoculars and telescope for you, and a smattering of science to help you understand a little about your place in the universe. It also shows you how to find and enjoy hundreds of achingly beautiful sights you will remember for the rest of your life.”

You have until noon (GMT) this Monday, March 24 to begin your personal odyssey through the heavens. As the Brian says, “You’ll come away from The Art of Stargazing with everything you need to become a skilled backyard stargazer.”

The cost is $197 USD, and there are payment plans, as well as a lifetime of followup information and email advisories. Get all the details here.

As always, you can find other ongoing classes at the CosmoQuest Academy. They regularly have new classes as well as opportunities for citizen science with their Moon Mappers, Asteroid Mappers and Planet Mappers programs.

There are also two astrophotography contests going on right now:

Ciel et Espace Photos in France is having their Photo Nightscape Awards, and are looking for submissions of Earth and night sky photos. Photos must be taken between January 1, 2014 and August 31, 2014. One photo submission per photographer, and all formats are accepted: panoramic, square, mosaics.

Prizes will be awarded Sunday, November 9, 2014 at the Rencontres Sky and Space (NCE) which will take place from 8 to 11 November 2014 at the Cité des Sciences et de l’Industrie.

They have two categories: pro and amateur. Prizes include a trip to the Very Large Telescope from ESO, a trip to the Alqueva Dark Sky Resever in Portugal for first prizes, and second prizes are a pair of Binocular from Nikon.

The judge for the contest is Miguel Claro, whose astrophotography we feature often here on Universe Today.

Get more information and find all the rules here.

A second photo contest comes from our friends at TWAN—The World At Night with their 5th annual International Earth and Sky Photo Contest, which is part of Global Astronomy Month in April 2014. The TWAN the contest is open to anyone of any age, anywhere around the world.

This year’s contest theme, “Dark Skies Importance,” has two categories: “Beauty of the Night Sky” and “Against the Lights.” Photos submitted to the contest should address either category: either to impress people on how important and amazing the starry sky is or to impress people on how bad the problem of light pollution has become. Both categories illustrate how light pollution affects our lives. Photographers can submit images to one or both categories.

Submitted photographs must be created in the “TWAN style” — showing both the Earth and the sky — by combining elements of the night sky (e.g., stars, planets, the Moon or celestial events) in the backdrop of a beautiful, historic, or notable location or landmark. This style of photography is called “landscape astrophotography”. This is similar to general “Nightscape Photography” but with more attention to the sky, astronomical perspectives, and celestial phenomena.

SpaceX Resets Space Station Launch with Revolutionary Rocket Legs and Robonaut Legs to March 30

KENNEDY SPACE CENTER, FL – Following last week’s sudden and late in the processing flow postponement of the SpaceX Falcon 9 rocket launch, SpaceX announced a reset of its next cargo mission launch for NASA to the International Space Station (ISS) to a new target date of Sunday, March 30.

The commercially developed Falcon 9 booster and Dragon cargo vessel are slated for a spectacular night time liftoff from Cape Canaveral Air Force Station in Florida at 10:50 p.m. EDT on March 30, SpaceX announced on Friday.

This mission, soaring to space under a resupply contract to NASA, could ignite a revolution in both rocketry and robotics.

The first stage of the Falcon 9 rocket sports a quartet of never before tried landing legs and the Dragon freighter is loaded with a set of lanky legs to enable mobility in space for NASA’s Robonaut 2 standing at the cutting edge of space robotics technology.

Launch preparations were suddenly halted less than 72 hours prior to the then planned March 16 early morning launch because of unspecified technical issues concerning the sudden discovery of “contamination,” sources told me.

“To ensure the highest possible level of mission assurance and allow additional time to resolve remaining open items, the team is taking additional time to resolve open items and ensure SpaceX does everything possible on the ground to prepare for a successful launch,” according to a statement from SpaceX.

Several sources told me that the problem related to “contamination” that was found in the “unpressurized truck section” at the rear of the Dragon spacecraft.

“An unknown contaminant of unknown origin was found on a blanket in the Dragon trunk,” independent sources said to Universe Today soon after the postponement was announced.

“After careful review and analysis, engineering teams representing both the ISS and SpaceX have determined Dragon is ready to fly ‘as-is.’ All parties agree that the particular constituents observed in Dragon’s trunk are in line with the previously defined environments levels and do not impose additional risk to the payloads,” SpaceX announced in a new statement.

With the contamination issues now resolved, the launch is back on track.

NASA Television will air live coverage on Sunday.

In case the launch is delayed, the backup launch opportunity is at 9:39 p.m. Wednesday, April 2.

Altogether, this unmanned SpaceX CRS-3 mission will deliver over 5000 pounds of science experiments, a pair of legs for Robonaut 2, a high definition imaging camera suite, an optical communications experiment and essential gear, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard the ISS soaring in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.

SpaceX is under contract to NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights over the next few years at a cost of about $1.6 Billion.

To date SpaceX has completed two operational cargo resupply missions and a test flight. The last flight dubbed CRS-2 blasted off a year ago on March 1, 2013 atop the initial version of the Falcon 9 rocket.

Following the rescheduled March 30 launch and a series of orbit raising and course corrections over the next two days, Dragon will rendezvous and dock at the Earth facing port on the station’s Harmony module on Wednesday, April 2.

Bill Nye on Taking Astronomy with Carl Sagan

“This is how we know nature. It is the best idea humans have ever come up with.”
– Bill Nye, Science Guy and CEO of The Planetary Society

In this latest video from NOVA’s Secret Life of Scientists and Engineers, science guy Bill Nye talks about the incredible influence that Carl Sagan had on his life, from attending his lectures on astronomy at Cornell University to eventually becoming CEO of The Planetary Society, which was co-founded by Sagan in 1980.

“I took astronomy from Carl Sagan.” Now there’s a statement that’ll get people’s attention. (It got mine, anyway.)

Space Geek Heaven: Man’s ‘Museum’ Contains Thousands Of Collectables

Part of the vast set of space memorabilia of Joe Lennox, a private collector based in the New York City area. Credit: Joe Lennox

We’re all space geeks at Universe Today and are used to seeing collections of memorabilia, but there’s something about Joe Lennox’s that makes us set our phasers to stunned. Ever since John Glenn first rocketed to space 52 years ago, Lennox has been amassing a collection of newspaper articles, astronaut autographs, books and other memorabilia that he has on display in his New York City-area home.

As a child, he had to fight to save stuff with his sister; they eventually agreed to a “joint venture”, Lennox said. For 10 years, they clipped newspapers, wrote to NASA astronauts and space program employees (collecting their responses), and started branching out to movies and other things covering space exploration. Their mother allowed them to display the items in a back bedroom. Eventually, the interest of Lennox’s sister faded, but his only deepened.

The collection has been through a few moves; his parents moved in 1978, meaning the stuff had to be stored wherever Lennox could find storage space until he and his wife bought their own house in 1990. There’s a spare bedroom available to display the collection, but the pictures indicate it’s simply bursting with items.

“My only problem is I don’t have enough room, because obviously as the years go by, I write (more) letters and purchase things,” Lennox told Universe Today.

Lennox makes sure to display his collection as carefully as he can. Scrapbook pages are acid-free, and letters are stored in acid-free folders as well. He says he has received space hardware (sometimes flown hardware) from contractors and others over the years, which he keeps in sealed display cases. Anything that remains outside of a sealed environment gets covered with a cloth when he’s not showing off the collection to house visitors.

It would be very difficult for a space fan to build such a collection today, he adds. NASA’s rules about “flown items” and other space memorabilia are tougher, with most items going to places such as the Smithsonian. Fewer people seem to answer his letters, too, Lennox said. “In the old days, if I wrote 100 letters, I would venture to say we got 95 really, really good responses. Today, if I wrote 100 letters I might get five responses. It’s very depressing, I got to tell you.”

With Lennox’s interest, a natural next question would be to ask if he ever considered working for NASA itself. While he never got that chance, the story ends up being a good one for the schoolkids he regularly speaks with.

Lennox said he never wanted to be an astronaut — “I’m not smart enough and don’t have the courage” — but he did have aspirations to be a flight controller. He said he began his university engineering studies with the idea for working for NASA, and happily worked away at his degree for a year and a half. Then he discovered he was going blind, requiring two corneal transplants.

The transplants worked, but it delayed his studies by four years and his eyesight was not as good as it used to be, meaning Lennox felt it was best to switch careers. He ended up in the banking industry, still writing letters to NASA and others the entire time. Now retired, he’s switching his energies over to teaching kids about space.

“I give presentations throughout New Jersey, 45 or 50 a year, where I go and I teach people about the space program,” he said. “I teach kids, I teach adults, I have probably 30 or 40 different presentations.”

His big message: “I want the children to understand they should never give up on their goals. If they have a goal in their life and it seems it can’t be reached because of health, like me, or money or relocation or whatever, they still can do it.”

360 Degrees of Milky Way at Your Fingertips

Touring the Milky Way’s a blast with this brand new 360-degree interactive panorama. More than 2 million infrared photos taken by NASA’s Spitzer Space Telescope were jigsawed into a 20-gigapixel click-and-zoom mosaic that takes the viewer from tangled nebulae to stellar jets to blast bubbles around supergiant stars.

Magnetic loops carry gas and dust above disks of planet-forming material circling stars, as shown in this artist's conception. These loops give off extra heat, which NASA's Spitzer Space Telescope detects as infrared light. The colors in this illustration show what an alien observer with eyes sensitive to both visible light and infrared wavelengths might see. Credit: NASA/JPL-Caltech/R.

The new composite, using infrared images taken over the past decade, was compiled by a team led by UW-Madison astronomer Barbara Whitney and unveiled at a TEDactive conference in Vancouver, Canada Thursday. Unlike visual light, infrared penetrates the ubiquitous dust concentrated in the galactic plane to reveal structures otherwise obscured.

“For the first time, we can actually measure the large-scale structure of the galaxy using stars rather than gas,” explained Edward Churchwell, UW-Madison professor of astronomy and team co-leader. “We’ve established beyond the shadow of a doubt that our galaxy has a large bar structure that extends halfway out to the sun’s orbit. We know more about where the Milky Way’s spiral arms are.”

Named GLIMPSE360 (Galactic Legacy Mid-Plane Survey Extraordinaire project), the deep infrared survey captures only about 3% of the sky, but because it focuses on the plane of the Milky Way, where stars are most highly concentrated, it shows more than half of all the galaxy’s 300 billion suns.

Using your imagination to hover high above the galactic plane, you’d see the Milky Way is a flat spiral galaxy sporting a stubby bar of stars crossing its central bulge. The solar system occupies a tiny niche in a minor spiral arm called the Orion Spur two-thirds of the way from the center to the edge. At 100,000 light years across, the Milky Way is vast beyond comprehension and yet it’s only one of an estimated 100 billion galaxies in the observable universe.

While you and I sit back and marvel at all the stellar and nebular eye candy, the Spitzer images are helping astronomers determine where the edge of the galaxy lies and location of the spiral arms. GLIMPSE images have already revealed the Milky Way to be larger than previously thought and shot through with bubbles of expanding gas and dust blown by giant stars.

Spitzer can see faint stars in the “backcountry” of our galaxy — the outer, darker regions that went largely unexplored before.

Barbara Whitney, co-leader of the GLIMPSE360 team

“There are a whole lot more lower-mass stars seen now with Spitzer on a large scale, allowing for a grand study,” said Whitney. “Spitzer is sensitive enough to pick these up and light up the entire ‘countryside’ with star formation.”

The new 360-degree view will also help NASA’s upcoming James Webb Space Telescope target the most interesting sites of star-formation, where it will make even more detailed infrared observations.

When you play around with the interactive mosaic, you’ll notice a few artifacts here and there among the images. Minor stuff. What took some getting used to was how strikingly different familiar nebulae appeared when viewed in infrared instead of visual light. The panorama is also available on the Aladin viewing platform which offers shortcuts to regions of interest.

Neil deGrasse Tyson, astrophysicist and host of the new Cosmos TV series, gave the third line of our “cosmic address” as the Milky Way after ‘Earth’ and ‘Solar System’. After a few minutes with GLIMPSE360 you’ll better appreciate the depth and breadth of our galactic home.

A Terrifying Virtual View Of Floating Away From The Space Station

You wanna talk about fear? This view would likely be many people’s worst nightmare — being in a spacesuit, untethered, floating away from the International Space Station and its relative safety. NASA has astronauts covered for this Gravity-type scenario, however, with a sort of jet backpack that can send astronauts back to safety.

A new video featuring European Space Agency astronaut Alexander Gerst (also embedded below) explains the steps an astronaut would take to swing back to safety. “We actually train how to use that in the virtual reality lab,” he said shortly after the video showed an astronaut floating away.

The key lies in a system called SAFER (Simplified Aid for EVA Rescue), which Gerst has practiced on numerous times (virtually) in preparation for his flight in May, which could involve spacewalks if NASA addresses a spacesuit water leak problem in time.

“You have to train it for a while to operate and actually come back, and not miss the station and fly into the blackness of space,” Gerst said.

The Russian Orlan spacesuit (which Gerst is also trained on) does not have such a system, but Roscosmos gets around that by having a different procedure for spacewalking than the Americans. The Russians mandate a minimum of two attachment points to station at all times, whether it’s a pair of tethers or a tether and a gripped hand.

Gerst emphasizes a floating away scenario is unlikely, in either case — it would involve losing the anchor, losing the tether and also losing your grip all at the same time. While this has never actually happened, NASA did test the SAFER system in space on STS-64 in 1994 with a crew member standing by on the Canadarm robotic arm if something went wrong. In 2000, two astronauts aboard STS-92 each did a 50-foot flight with the system.

In 2006, the SAFER system got a little loose on the back of astronaut Piers Sellers, necessitating a tether fix. NASA emphasized that the system was not in danger of being lost.

You can view the section on SAFER in the video below at around 6 minutes. Gerst recorded this as a summary of his training ahead of Expedition 40/41, which lifts off in May.
