It is like coming around a corner and seeing the most magnificent sunset of your life, from one horizon to the other where it looks like the whole sky is on fire and there are all those colors, and the sun’s rays look like some great painting up over your head. You just want to open your eyes wide and try to look around at the image, and just try and soak it up. It’s like that all the time. Or maybe the most beautiful music just filling your soul. Or seeing an absolutely gorgeous person where you can’t just help but stare. It’s like that all the time.
Late in Hadfield’s final mission to space this May, when the Canadian Space Agency (CSA) astronaut was commanding the International Space Station Expedition 35 crew, an ammonia leak happened and NASA had to scramble a plan for a spacewalk, or extravehicular activity (EVA), to fix it. (The fix succeeded.) When Hadfield was apprised of the plan, he says in an excerpt from his forthcoming book, he was disappointed:
I wasn’t going out. I had a moment where I allowed myself to experience the full force of my disappointment. This would have been the heroic climax of my stint as commander: helping to save the ISS by doing an emergency spacewalk. I’d never have another chance to do an EVA—I’d already informed the CSA that I planned to retire shortly after returning to Earth.
But Chris [Cassidy] and Tom [Marshburn] had both done three previous EVAs, two of them together, on the same part of the station where ammonia was now leaking. They were the obvious people for the job. All this went through my head and heart for a minute or two, then I made a resolution: I was not going to hint that I’d had this pang of envy, or say, even once, that I wished I was doing the EVA. The right call had been made, and I needed to accept it and move on so that we could all focus on the main thing—the only thing, really: working the problem.

The astronauts on board the International Space Station saw a strange and unexpected view out their windows yesterday. “Saw something launch into space today. Not sure what it was but the cloud it left behind was pretty amazing,” tweeted NASA astronaut Mike Hopkins.
ESA astronaut Luca Parmitano also got a shot of the cloud, as well as another picture of a contrail left from the launch.
So what launched into space? Of course, there was no launch from NASA because of the government shutdown, and I couldn’t find any other launches on the docket anywhere else, so I checked in with Robert Christy at the Zarya.info website, who usually knows of everything going up (or down) in space.
‘A missile launch seen from space: an unexpected surprise!’ tweeted ESA astronaut Luca Parmitano. Credit: ESA/Luca Parmitano.
“Without precise date, time and location it’s not possible to say for sure,” Christy replied, “I believe there was a missile launch from Kapustin Yar (Kazakhstan) on October 10 so if the photo was taken over the Eastern Europe or central Asia region than that might be what he saw.”
Strategic Rocket Forces carried out a successful test launch of a Topol/SS-25 missile on October 10, 2013. The missile was launched at 17:39 MSK (13:39 UTC) from Kapustin Yar to the Sary Shagan test site in Kazakhstan. According to a representative of the Rocket Forces, the test was used to confirm characteristics of the Topol missile, to test the systems of the Sary Shagan test site, and “to test new combat payload for intercontinental ballistic missiles.”
I had thought ICBM’s were a relic of the Cold War, but according to Wikipedia, “As of 2009, all five of the nations with permanent seats on the United Nations Security Council have operational long-range ballistic missile systems: all except China have operational submarine-launched missiles, and Russia, the United States and China also have land-based ICBMs (the US’ missiles are silo-based, China and Russia have both silo and road-mobile missiles).” Additionally, Israel launched an ICBM test in 2008, India test-fired one in 2012 and there was much speculation that a launch by North Korea in December 2012 to put a satellite into orbit was really a way to test an ICBM.
Parmitano also got an image of the cloud:

“An immense cloud forms outside the atmosphere after the disintegration,” Parmitano said via Twitter.
Robert Christy noted that at the launch time noted by the RussianForces website, the ISS was over Iran, heading northeast towards Mongolia, and the Sun was about to set at Kapustin Yar.
“The view from the ISS would have been with a low sun angle, shining ‘over the photographer’s shoulder’ – hence the rather striking image against a darkish background with no glare from the Sun,” Christy told Universe Today via email.
Oh, the things you can see out your window in space!

Who doesn’t love Mars? Amid the bad news of a U.S. government shutdown now stretching towards Day 12, there are still several spacecraft from NASA and the European Space Agency taking pictures of that red dot in the sky. Here are some recent stunners from the Red Planet.
Above is an infrared view of Noachis Terra as seen through the eyes of the Mars Reconnaissance Orbiter. The High Resolution Imaging Science Experiment (HiRISE) camera website (from the University of Arizona) released the picture on its website Oct. 2, with this description (in part):
“When there are perfect conditions for producing sand dunes — steady wind in one direction and just enough sand — barchan sand dunes form. The word ‘barchan’ is a Russian term because this type of dune was first described in the desert regions of Turkistan.”
MRO is run under a contract from NASA and is still operating, although its Twitter feed warns funds are running low.

Mars Express is a European Space Agency spacecraft and is thus not affected by the shutdown. This mosaic of eight images released Oct. 8 (above) shows Hebes Chasma, which is about 186 miles (300 kilometers) north of Valles Marineris. The trench is about five miles (eight kilometers) deep at its utmost, and hundreds of miles long. “A flat-topped mesa is located in the center of Hebes Chasma, which was likely shaped by the action of wind and water,” ESA wrote.
Meanwhile, the Curiosity and Opportunity rovers are still trundling away on Mars. NASA’s Jet Propulsion Laboratory is a contract operation and is still running its missions for the time being. These pictures were downloaded from the raw image sites for the rovers (here and here) as all press updates are suspended amid the shutdown.

Following the speed boosting slingshot of Earth on Wednesday, Oct. 9, that sent NASA’s Juno orbiter hurtling towards Jupiter, the probe has successfully transmitted back data and the very first flyby images despite unexpectedly going into ‘safe mode’ during the critical maneuver.
“Juno is transmitting telemetry today,” spokesman Guy Webster, of NASA’s Jet Propulsion Lab (JPL), told me in a phone interview late today (Oct. 10), as Juno continues sailing on its 2.8 Billion kilometer (1.7 Billion mile) outbound trek to the Jovian system.
The new images of Earth captured by the Junocam imager serves as tangible proof that Juno is communicating.
“Juno is still in safe mode today (Oct. 10),” Webster told Universe Today.
“Teams at mission control at JPL and Lockheed Martin are actively working to bring Juno out of safe mode. And that could still require a few days,” Webster explained.
Lockheed Martin is the prime contractor for Juno.
The initial raw images of Earth snapped by the craft’s Junocam imager were received by ground stations late today.
See above a day light image mosaic which I reconstructed and realigned based on the original raw image (see below) taken with the camera’s methane filter on Oct. 9 at 12:06:30 PDT (3:06:30 PM EST). Juno was to be flying over South America and the southern Atlantic Ocean.

Juno performed a crucial swingby of Earth on Wednesday that accelerated the probe by 16330 MPH to enable it to arrive in orbit around Jupiter on July 4, 2016.
However the gravity assist maneuver did not go entirely as planned.
Shortly after Wednesday’s flyby, Juno Project manager Rick Nybakken, of JPL, told me in a phone interview that Juno had entered safe mode but that the probe was “power positive and we have full command ability.”
“After Juno passed the period of Earth flyby closest approach at 12:21 PM PST [3:21 PM EDT] and we established communications 25 minutes later, we were in safe mode,” Nybakken explained.
The safe mode was triggered while Juno was in an eclipse mode, the only eclipse it will experience during its entire mission.
The Earth flyby did accomplish its objective by placing the $1.1 Billion Juno spacecraft exactly on course for Jupiter as intended.
“We are on our way to Jupiter as planned!”
“None of this affected our trajectory or the gravity assist maneuver – which is what the Earth flyby is,” Nybakken stated.
Juno’s closest approach was over South Africa at about 561 kilometers (349 miles).
During the flyby, the science team also planned to observe Earth using most of Juno’s nine science instruments since the slingshot also serves as a key test of the spacecraft systems and the flight operations teams.
Juno also was to capture an unprecedented new movie of the Earth/Moon system.
Many more images were snapped and should be transmitted in coming days that eventually will show a beautiful view of the Earth and Moon from space.
“During the earth flyby we have most of our instruments on and will obtain a unique movie of the Earth Moon system on our approach, Juno principal investigator Scott Bolton told me. Bolton is from the Southwest Research Institute (SwRI), San Antonio, Texas.
“We will also calibrate instuments and measure earth’s magnetosphere, obtain closeup images of the Earth and the Moon in UV [ultraviolet] and IR [infrared],” Bolton explained to Universe Today.
Juno is approaching the Earth from deep space, from the sunlit side.
“Juno will take never-before-seen images of the Earth-moon system, giving us a chance to see what we look like from Mars or Jupiter’” says Bolton.
Here is a description of Junocam from the developer – Malin Space Science Systems
“Like previous MSSS cameras (e.g., Mars Reconnaissance Orbiter’s Mars Color Imager) Junocam is a “pushframe” imager. The detector has multiple filter strips, each with a different bandpass, bonded directly to its photoactive surface. Each strip extends the entire width of the detector, but only a fraction of its height; Junocam’s filter strips are 1600 pixels wide and about 155 rows high. The filter strips are scanned across the target by spacecraft rotation. At the nominal spin rate of 2 RPM, frames are acquired about every 400 milliseconds. Junocam has four filters: three visible (red/green/blue) and a narrowband “methane” filter centered at about 890 nm.”

During a one year long science mission – entailing 33 orbits lasting 11 days each – the probe will plunge to within about 3000 miles of the turbulent cloud tops and collect unprecedented new data that will unveil the hidden inner secrets of Jupiter’s origin and evolution.

As we reported yesterday, the latest data on Comet ISON indicates there is some encouraging news as far as the Comet surviving perihelion, its closest approach to the Sun. While some are all doom and gloom about the potential for Comet ISON putting on a good show, these latest images indicate that as of now, this comet is alive and doing well!
“We really do not know what comet ISON is going to do when it gets near the Sun,” wrote astronomer Karl Battams of the Comet ISON Observing Campaign website. “But what we can say for certain, right now, is that comet ISON is doing just fine! It continues to behave like a fairly typical, if somewhat smaller-than-average, Oort Cloud comet. It has given no indication that it has fragmented and while such an event can never be ruled out, we see no evidence or hint that the comet is in any imminent danger of doing so. Any reports to the contrary are just speculation.”
You can read more from Battams about the current status of ISON, but just take a look at some of these gorgeous latest images from a variety of astrophotographers:

Better yet, try and see it for yourself! As of now, you’ll need to find someone with a fairly good telescope, so check out your local amateur astronomy club or observatory and find out when they are planning on viewing ISON. And if the comet can hold itself together, we’re all holding out hope that it will be visible with the naked eye after is passes by the Sun in late November. Here’s our detailed viewing guide from now until perihelion.

One of the original “Mercury 7” astronauts, Scott Carpenter, has died. He was the sixth person to fly in space; the fourth American to fly in space and the second US astronaut to orbit Earth. Carpenter died on Thursday, October 10, 2013 at age 88 after suffering a recent stroke. With the death of Carpenter, the only remaining surviving member of the original US astronauts is John Glenn.
collectSPACE is reporting that Carpenter was being cared for at a hospice center in Denver when he passed. Carpenter was initially expected to make a full recovery from the stroke, but his condition worsened this week, sources close to his family shared.
Carpenter was chosen as an astronaut in 1959. He launched in his Aurora 7 capsule on May 24, 1962 in the fourth manned mission and the second orbital flight of the Mercury program. The video below celebrates the Aurora 7 flight, which successfully made three Earth orbits. But a targeting mishap during reentry took the spacecraft about 400 km (250 miles) off course, delaying recovery of Carpenter and the capsule. Carpenter was picked up after nearly 3 hours in the water, and the Mercury capsule was not retrieved until about 6 hours later.
Carpenter said of his flight, “The zero-g sensation and the visual sensation of space flight are transcending experiences, and I wish everybody could have them.”
Carpenter was born on n May 1, 1925. He is survived by his wife, seven children, two step-children and six grandchildren.
Almost every part of a rocket is destroyed during the launch and re-entry into the Earth’s atmosphere. This makes spaceflight really expensive. Rocket delivery of even a single kilogram into orbit costs tens of thousands of dollars. But what if we could just place our payloads directly into orbit, and didn’t need a rocket at all?
This is the idea of a space elevator, first envisioned by the Russian rocket scientist Konstantin Tsiolkovsky in 1895. Tsiolkovsky suggested building a tower all the way up to geostationary orbit, this is the point where a satellite appears to hang motionless in the sky above the Earth. If you could carry spacecraft all the way up to the top, and release them from that tower they’d be in orbit, without the expense of a discarded rocket. A fraction more energy and they’d be traveling away from the Earth to explore the Solar System.
The major flaw with this idea is that the entire weight of the tower would be compressing down on every part below. And there’s no material on Earth, or in the Universe, that can handle this kind of compressive force. But the idea still makes sense.
Newer thinking about space elevators propose using a cable, stretched out beyond geostationary orbit. Here the outward centripetal force counters the force of gravity, keeping the tether perfectly balanced. But now we’re dealing with the tensile strength of a cable tens of thousands of kilometers long.
Imagine the powerful forces trying to tear it apart. Until recently, there was no material strong enough to withstand those forces, but the development of carbon nanotubes has made the idea more possible.
How would you build a space elevator? The most reasonable idea would be to move an asteroid into geostationary orbit – this is your counterbalance. A cable would then be manufactured on the asteroid, and lowered down towards the Earth.
As the cable extends down, the asteroid is orbited further from the Earth, keeping everything in balance. Finally, the cable reaches the Earth’s surface and is attached to a ground station.

Solar powered machines are attached to the space elevator and climb up from the surface of the Earth, all the way to geostationary orbit. Even traveling at a speed of 200 km/hour, it would take the climber almost 10 days to make the journey from the surface to an altitude of 36,000 kilometers. But the cost savings would be dramatic.
Currently, rockets cost about $25,000 per kilogram to send a payload to geostationary orbit. A space elevator could deliver the same payload for $200 per kilo.
Obviously there are risks associated with a megastructure like this. If the cable breaks, portions of it would fall to Earth, and humans traveling up in the elevator would be exposed to damaging radiation in the Earth’s Van Allen belts.
Building a space elevator from Earth is at the very limits of our technology. But there are places in the Solar System which might make much more useful places to build elevators.
The Moon, for example, has a fraction of the Earth’s gravity, so an elevator could operate there using commercially available materials. Mars might be another great place for a space elevator.
Whatever happens, the idea is intriguing. And if anyone does build a space elevator, they will open up the exploration of the Solar System in ways that we can’t even imagine.

The Earth is warming up.
Ocean temperatures are rising. Arctic sea ice is melting. Atmospheric carbon dioxide levels are growing. The oceans are becoming more acidic. The weather is already more extreme.
With the release of the fifth Assessment Report by the Intergovernmental Panel on Climate Change – a panel of more than 2,500 experts, more commonly known as the IPCC – it’s clear that climate change is very real. But it’s especially clear that we are the cause. If we don’t act now by taking vigorous action to reduce emissions the results will be catastrophic.
Toward the end of this 900-page report, the IPCC looked toward our future, focusing on the climate after the year 2100. Here, Universe Today, explores two extreme scenarios for the Earth by 2100.
1.) Embracing the Challenges of Climate Change
The conclusions reached by climate scientists at the end of the 21st Century were undeniable. We embraced climate change by investing heavily in renewable energies. Both large-scale companies and individuals bought energy drawn from the sunlight, wind, and geothermal heat.
Homes across the world became more sustainable. Their total square feet shrunk, as home owners learned to live with less. It was not uncommon to dress a roof with plants or solar panels. Even the layout of homes changed. They rested partially underground, taking advantage of geothermal heat, and faced South (in the case of the Northern hemisphere) to take advantage of the warm sunlight.
We also embraced geoengineering technologies. We added artificial clouds to our atmosphere, which reflected sunlight, and built towers to collect greenhouse gas emissions. The gases are now trapped deep underground. Our goal was not only to slow the process of climate change, but to stop it, and quite possibly reverse it.
We now eat far less meat than we did in the early 21st Century to cut the emissions generated from livestock farming. Pastures have been replaced with booming forests – helping to absorb CO2. We also eat more locally.
The world followed in China’s footsteps and restricted couples to a certain number of children, reducing our overall population.
We live in small compact cities where we drive hybrid cars and take public transport to work. Carbon offsets must be purchased when taking long trips. Most families vacation in their own backyard – exploring all that nature has to offer in the nearby vicinity.
We viewed climate change as an exciting opportunity to embrace the needs of our environment. We now live much simpler lives and the census shows that our overall intelligence and happiness is much higher than it was a century ago.
2.) The Point of No Return
We simply didn’t want to face the facts. We live in a global economy with a population that has increased significantly over the last century. Most of our energy still comes from fossil fuels. We never invested in renewable energies.
We measure our happiness based on the cars we drive, the number of material possessions we can cram into our large homes, and how often we travel the globe.
The world is, on average, 9 degrees warmer. The entire arctic has melted. Ocean levels have risen by over a meter – flooding coastal communities across the world. Millions have been left homeless.
Our weather is extreme. Hurricanes, tornadoes, fires, floods, draughts, and earthquakes kill hundreds of thousands per year. Climate change has devastated food production and water supplies.
Air quality is much poorer across the world. Due to haze, it is perfectly safe to look at the sun directly. We can only see a third of the stars visible a century ago.
We have triggered various tipping points. The thawing of permafrost released further CO2 and methane. Large areas of the planet are becoming uninhabitable. Our efforts are working toward damage control only. We fear that it may be too late.
Climate change is still in our hands, but we have to act now.
The fifth Assessment Report by the IPCC may be found here. Emphasis in this article may be found in the long term climate change section, as well as descriptions published by the IPCC in 2000.

With the government shutdown, news out of NASA is sometimes sparse. But thankfully amateur astronomers can fill in some of the holes! While Juno’s project manager Rick Nybakken has confirmed that the spacecraft successfully completed its slingshot flyby of Earth yesterday, images taken by amateur astronomers around the world also conclusively confirm that Juno is now “bang on target!” tweeted Nick Howes of the Remanzacco Observatory team. This image from Howes, Ernesto Guido and Martino Nicolini shows the path of Juno across the sky, as seen from a remote telescope in Spain. “The spacecraft is trailed in the image due to its fast speed,” the team wrote on their website, and extrapolations of Juno’s orbit shows it is heading straight for Jupiter.
You can see a gallery of images of Juno’s flyby taken by amateurs on this SpaceWeather.com page.
Meanwhile, there are some concerns about the spacecraft going into safe mode immediately after the flyby. Our previous article by Ken Kremer reported that the mission teams are assessing the situation, and that the spacecraft is “power positive.”
One idea of why the spacecraft went into safe mode is that the battery was being depleted faster than anticipated, but the team is still working to confirm the reason.
Closest approach was at 12:21 PM PST (19:21 UTC, 3:21 PM EDT).
For more information about the flyby, check out this new video from Bill Nye the Science Guy — who has a new video series called “Why With Nye.”

A smash-up that created Pluto’s largest moon, Charon, likely sprayed debris four billion years ago that formed the genesis of the other moons scientists are spotting today, a new study concludes.
The find could explain why the satellites Styx, Nix, Kereberos and Hydra have orbital periods that are, respectively, just about exactly 3, 4, 5 and 6 times longer than Charon’s, scientists said.
“Any initially surviving satellites would likely be destroyed in collisions, but these shattered moons wouldn’t be lost; rather, their remains would stay in the Pluto/Charon system and become the starting point for building new satellites,” stated the Southwest Research Institute (SWRI), which led the study.

“In modeling the destruction of the satellites, the SWRI study found that there may be a method for moving them, or their building blocks, outward, due to the competing effects of Charon’s gravitational kicks and collisions among the debris of the disrupted satellites.”
Given Charon’s large size relative to Pluto (it’s a tenth of the dwarf planet’s size, compared to the Earth-Moon 81: 1 ratio), its large mass could easily perturb these smaller moons if they got close. Also, collisions between the debris could alter the orbits “to keep things away from Charon”, the scientists said.
The findings were presented yesterday (Oct. 9) at the American Astronomical Association’s division of planetary sciences meeting in Denver; information on whether the results are peer-reviewed was not immediately available.
