Canadian astronaut Chris Hadfield has been sharing with us how much there is to learn and the training necessary for living on the International Space Station for five months. But astronauts and cosmonauts also have to learn how to fly on the Russian Soyuz, too, as right now, there’s no other ride to the space station.

“Soyuz is a wonderful spaceship,” Hadfield told Universe Today. “It has been refined and honed and perfected for decades, as if they took an early sculpture of something and have continuously whittled away at it to make it more and more purpose-built and improved.”

The most modern version, the TMA-M, is as good as they’ve ever made it, Hadfield said, with great modifications and improvements in avionics, sensors, computing power.

“So, it is a very capable, well-designed vehicle; a tough vehicle,” he said. “That is heartening and reassuring. It has the full ability to do almost everything on its own, but also full ability for us to take over and do almost everything manually if we need to.”

“There is an unbelievable thrill in getting into your own spaceship. This is the same hatch we’ll use on the launch pad,” Hadfield said via Twitter.

It is so robust that with just a stopwatch, the crews can bring it safely back to Earth and land within a 10-km circle of where they want to touch down.

All the training is in Russian. “Russian digital motion control theory is complex,” Hadfield said. “It took a full year of intensive one-on-one study to become ready to start flying the Soyuz.” This video shows Hadfield working in the simulator:

Hadfield said that not only does he have great respect for the Soyuz, but for the training provided by the Russian Space Agency, Roscosmos.

“They simulate it well, and they load us up to our limit of what they teach us,” he said, “getting into the very esoteric and complex things that can happen.”

For example, in full-up simulations where the crew are in the pressure suits, the trainers will do things like fill the cockpit with smoke as if there was a fire on board, so the “dashboard” can’t be seen, and the crew needs to know how to keep flying.

“Centrifuges make you dizzy while they accelerate & decelerate, & REALLY mess you up when you move your head. Otherwise OK,” Hadfield Tweeted.

In this video, Hadfield explains the Soyuz centrifuge, the largest human-rated centrifuge in the world, that puts the astronauts and cosmonauts in the same environment – G-force-wise – that they will be in during the harrowing descent when they return home, plummeting through Earth’s atmosphere and experience 4-8 times the force of Earth’s gravity.

“You need to be able to understand how that feels on your body and whether you are going to be able to work in that environment,” Hadfield said.

“Hatch to Another World – what it looks like to climb into a Soyuz spaceship. We then crawl down into our seats,” Hadfield said, via Twitter.

The Soyuz rocket is just as robust and one of the most reliable rockets ever. “The Soyuz launches all-weather, -40 degrees to +40 degrees,” Hadfield said. “It is rugged, built on experience, it is not delicate. I trust it with my life.”

“It takes these 32 engines to get these 3 humans safely above the air. And that’s just the start,” Hadfield said via Twitter.

“My Soyuz Checklists – from L to R: Launch/Entry, Malfunctions, Orbital Flight. Colour-coded for easy spaceflight,” said Hadfield via Twitter.

Hadfield talks about the Russian technology for the rocket and spaceship he will be flying in:

Hadfield’s son and daughter-in-law gave him a Soyuz-like pre-flight Christmas present:

“My first Soyuz simulator! Summer 1964, nearly 5 years old. Never too early to start training,” Hadfield shared on Twitter.

Gorgeous New Backlit View of Saturn

NASA’s Cassini spacecraft has delivered a glorious view of Saturn, taken while the spacecraft was in Saturn’s shadow. Image credit: NASA/JPL-Caltech/Space Science Institute

The Cassini team has done it again. A new 60-image mosaic of Saturn shows a back-lit view of the giant ringed world in several wavelengths, making Saturn look like a colorful holiday ornament. In October, the Cassini spacecraft was deliberately positioned within Saturn’s shadow, and the cameras were turned toward Saturn and with the Sun behind the planet.

“Of all the many glorious images we have received from Saturn, none are more strikingly unusual than those taken from Saturn’s shadow,” said Carolyn Porco, Cassini’s imaging team lead based at the Space Science Institute in Boulder, Colorado. “They unveil a rare splendor seldom seen anywhere else in our solar system.”


“Looking back towards the Sun is a geometry referred to by planetary scientists as “high solar phase;” near the center of the target’s shadow is the highest phase possible,” the Cassini team explained. Not only does this produce a stunning image, but it is very scientifically advantageous as well, as it can reveal details about both the rings and atmosphere that cannot be seen in lower solar phase.

This is a rare view, as the last time the Cassini spacecraft was able to take a backlit view of Saturn and the rings was 2006. Also captured in this image are two of Saturn’s moons: Enceladus and Tethys. Both appear on the left side of the planet, below the rings. Enceladus is closer to the rings; Tethys is below and to the left.

The black area at the top of Saturn is the planet’s shadow on the rings.

One of the Largest Astronomical Images Ever Made

The northern portion of the Cygnus Loop, as seen in an enormous new panorama from the National Optical Astronomy Observatory (NOAO) and WIYN partners

Looking for a stunning new desktop image to wrap up the year? Try this: it’s an amazing panorama of the Cygnus Loop, a supernova remnant located 1,500 light-years away in the constellation (you guessed it) Cygnus. The full-size image, acquired with the wide-field Mosaic camera on the WIYN 0.9-meter telescope at Kitt Peak, Arizona, is a staggering 600 million pixels in size — over 1.68 gigabytes — making it one of the largest astronomical images ever made!

See the full image (and links to download larger versions) below:

2000-pixel-wide version of the full Cygnus Loop panorama

The entire structure of the Cygnus Loop, the gaseous remains of a supernova that occurred 5,000 – 10,000 years ago, covers an area nearly 45 times the size of the full Moon in the sky.

In the image, hydrogen alpha, sulphur, and oxygen ions correspond to the red, green, and blue color values, respectively.

“Images like this are amazing because they can remind you of the big picture and beauty that surrounds us.”

–  Dr. Richard Cool, MMT Observatory

From the NOAO press release:

Astronomers estimate the supernova explosion that produced the nebula occurred between 5,000 to 10,000 years ago. First noted in 1784 by William Herschel, it is so large that its many parts have been catalogued as separate objects, including NGC 6992, NGC 6995 and IC 1340 along the eastern (left) side of the image, NGC 6974 and NGC 6979 near the top-center, and the Veil Nebula (NGC 6960) and Pickering’s Triangle along the western (right) edge. The bright star near the western edge of the image, known as 52 Cygnus, is not associated with the supernova.

“Often, astronomical research reduces images to dry tables of numerical information that we analyze in order to more deeply understand our universe,” said Dr. Richard Cool, astronomer at the MMT Observatory in Arizona, who originally obtained the images in 2003 while still a graduate student. “Images like this are amazing because they can remind you of the big picture and beauty that surrounds us.”

This incredible image demonstrates that even relatively small telescopes are capable of producing cutting-edge research, when equipped with modern cameras.

Update on ‘Chasing Atlantis’ Film

They didn’t reach their money goal, but the Chasing Atlantis team still sounds pretty pleased about the result: the independent movie-making team raised $5,610 to help with the final costs of production.

As previously reported in Universe Today, the Canadian team launched an Indiegogo campaign on Nov. 5 to raise up to $15,000 from people visiting the crowdsourcing site. Indiegogo allows teams to keep all funds donated, even if the goal is not reached.

“Thank you so much for all your support, contributions, and the belief in this film. Last night, at the conclusion of our 47-day Indiegogo campaign, we raised $5,610,” the team wrote on their official blog today (Dec. 18).

The project, which was entirely self-funded before this campaign, followed the last launch of space shuttle Atlantis in 2011. The movie will include appearances from Star Trek: The Next Generation‘s Wil Wheaton as well as Chris Hadfield, who will launch to space on Expedition 34 tomorrow. He will be the first Canadian to command the International Space Station.

The team is en route to the Canadian Space Agency’s headquarters near Montreal, Quebec today for a fresh round of interviews; the agency is hosting a Hadfield launch party tomorrow. More announcements on the film’s progress will come in the next few months.

Behold! Hubble’s Heavenly Holiday “Ornament”

It may be just a tad too big to hang on your tree but this bright, twisted planetary nebula would make a beautiful holiday ornament… if scaled a bit down to size, of course.

(Click the image to see it in its full festive glory!)

NGC 5189 is a planetary nebula that lies 1,800 light-years away in the southern constellation Musca. The gorgeous image above, acquired by Hubble’s Wide Field Camera 3 on October 8, 2012, shows the glowing streamers of oxygen, sulfur and hydrogen that are being blown far into space from the hot star star at its heart — HD 117622 (at right.)

The expelled gas forms a double structure, with a series of central blue lobes surrounded by a twisted helix of bright streamers, called radial filaments. These filaments are the result of fast-moving material from the star impacting previously expelled, slower-moving gas, which becomes visible due to ionizing radiation.

The twisted shapes — as opposed to the circular or spherical structures found in many planetary nebulae — may be the result of an unseen binary partner to HD 117622, which over time would affect its rotational orientation.

“The likely mechanism for the formation of this planetary nebula is the existence of a binary companion to the dying star,” said scientist Kevin Volk in a Gemini Observatory article from 2006. “Over time the orbits drift due to precession and this could result in the complex curves on the opposite sides of the star.”

The surrounding stars in the image were captured in visible and near-infrared light.

‘NASA Johnson Style’ Parodies ‘Gangnam Style’ Music Video

Check this out and get in the groove to enjoy some really cool fun from NASA

NASA interns and NASA astronauts have joined forces to create a very humorous and entertaining music video parody of the “Gangnam Style” mega hit by international pop sensation PSY – It’s called “NASA Johnson Style” and its New!

A team of interns from NASA’s Johnson Space Center (pictured below) in Houston created original lyrics, convinced several initially incredulous astronauts to dance along and shot the video at several NASA centers. Then they integrated the whole kit and kaboodle with the “Gangnam Style” instrumental track. Scotty would be proud of the intricate engineering demanded to pull this off – but where are the tribbles !

Image caption: Mike Massimino (center) poses with the intern video team after filming at JSC. Photo credit: Nicole Cloutier

The video features a fun loving crew of NASA astronauts including Mike Massimino, who deftly repaired the Hubble Space Telescope twice among other things, Clayton Anderson and Tracy Caldwell Dyson who lived and worked for many months aboard the International Space Station, and Mike Coats, a Shuttle commander and the retiring Director of the Johnson Space Center.

The video also features actual footage from the International Space Station , Apollo Moonwalks, Curiosity on Mars, Dawn at Vesta, Houston Mission control, the SLS and Orion Crew vehicle as well as real research labs and scientists here on Earth. So it’s fun and meant to be educational as well.

“Gangnam Style” by the Korean singing star PSY is the most popular YouTube music ever and is enjoyed by millions more every day since it was released last summer. It has spawned numerous other parodies.

And in case you missed last summer’s mega hit parody straight from the Red Planet – click on this: “We’re NASA and We Know It (Mars Curiosity)” – Note: this is NOT a NASA production

Now, turn up the volume and enjoy some light hearted cheer in this Holiday season.

Russia’s Soyuz Spacecraft: 46 Years and Still Soaring High


In just a couple of days a Soyuz rocket will lift off from the Baikonur Cosmodrome, carrying NASA astronaut Tom Marshburn, Canadian Space Agency astronaut Chris Hadfield, and Russian Federal Space Agency cosmonaut Roman Romanenko within the TMA-07M capsule on a two-day trip to the ISS. While many improvements have been made to the Soyuz rockets and spacecraft since the first launch in 1966, the bottom line is that the Soyuz have become the world’s most used launch vehicles due to their consistent performance and relatively low cost.

Here, CSA astronaut Chris Hadfield talks about the Soyuz, briefly describing the strengths of the Russian technology that will once again take him and fellow Expedition 34/35 crew members to the ISS, where in March of next year he will become the first Canadian to take command of the Station.

“This is a safe and reliable and proven way to leave the Earth, and each successive Soyuz is different; each one has small changes. The role of the astronaut is to learn those small changes… and learn to apply them.”

– Canadian astronaut Chris Hadfield

The T version of the Soyuz craft began flying manned missions in 1980 and in 1986 the TM versions were transporting crews to Mir. The TMA upgrade addressed previous astronaut/cosmonaut height restrictions and permits the Soyuz to be used as a lifeboat for ISS crews, if necessary.

Find out more about the long history of the Soyuz spacecraft here, and read more about today’s Soyuz rollout here.

End of Mission: GRAIL Spacecraft Impact a Mountain on the Moon

“So long, Ebb and Flow, and we thank you,” said GRAIL project manager David Lehman of NASA’s Jet Propulsion Laboratory after the twin GRAIL spacecraft completed a planned formation-flying double impact into the southern face of 2.5-kilometer- (1.5-mile-) tall mountain on a crater rim near the Moon’s north pole. Mission team members estimate the two spacecraft were traveling at a speed of 1.7 kilometers per second (3,760 mph), and likely broke apart on impact. NASA said that most of what remains of the washing machine-sized spacecraft are probably buried in shallow craters, and the size of those craters will hopefully be determined when NASA’s Lunar Reconnaissance Orbiter is able to image the impact site in about two weeks.

NASA has honored the GRAIL team’s request to name Ebb and Flow’s impact sites after astronaut Sally Ride, who passed away earlier this year. She was America’s first woman in space and a member of the GRAIL mission team.

A simulation of the GRAIL impacts:

Impact occurred at 10:28:51 UTC (5:28:51 p.m. EST) and 10:29:21 UTC (5:29:21 p.m. EST). Right now it is night at the impact site, so sunlight should return within two weeks, enabling imaging of the site. LRO also took “before” images of the site during previous daylight orbits.

The impact marked a successful end to the GRAIL(Gravity Recovery and Interior Laboratory)mission, which in just a 90-day prime mission generated the highest-resolution gravity field map of any celestial body — including Earth — and determined the inner crust of the Moon is nearly pulverized.

“Ebb and Flow have removed a veil from the Moon,” said GRAIL principal investigator Maria Zuber during a televised commentary of the impacts today, adding that the mission will enable discoveries for years to come.

Data from GRAIL’s extended mission and main science instruments are still being analyzed, and the findings will provide a better understanding of how Earth and other rocky planets in the solar system formed and evolved.

GRAIL was NASA’s first planetary mission to carry cameras fully dedicated to education and public outreach. Ride, who died in July after a 17-month battle with pancreatic cancer, led GRAIL’s MoonKAM (Moon Knowledge Acquired by Middle School Students) Program through her company, Sally Ride Science. The camera took more than 115,000 total images of the lunar surface, and imaging targets were proposed by middle school students from across the country and the resulting images returned for them to study.

“Sally was all about getting the job done, whether it be in exploring space, inspiring the next generation, or helping make the GRAIL mission the resounding success it is today,” said Zuber. “As we complete our lunar mission, we are proud we can honor Sally Ride’s contributions by naming this corner of the Moon after her.”

Last Friday, Ebb and Flow, the two spacecraft comprising NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, were commanded to descend into a lower orbit that would result in an impact Monday on a mountain near the Moon’s north pole.

Fifty minutes prior to impact, the spacecraft fired their engines until the propellant was depleted. The maneuver was designed to determine precisely the amount of fuel remaining in the tanks. This will help NASA engineers validate computer models to improve predictions of fuel needs for future missions.

Screenshot of engineering data showing trajectory of the two GRAIL spacecraft about 2 minutes before Ebb’s impact. Via NASA TV.

“Ebb fired its engines for 4 minutes 3 seconds, and Flow fired its for 5 minutes 7 seconds,” Lehman. “It was one final important set of data from a mission that was filled with great science and engineering data.”

Launched in September 2011, Ebb and Flow had been orbiting the moon since Jan. 1, 2012. The probes were intentionally crashed into the lunar surface because they did not have sufficient altitude or fuel to continue science operations.
