Expedition 37 crew members Karen Nyberg of NASA, Fyodor Yurchikhin of the Russian Federal Space Agency and Luca Parmitano of the European Space Agency have returned to Earth from the International Space Station, landing at 9:49 p.m. EST Sunday, Nov. 10 (02:49 UTC, 8:49 a.m. Kazakhstan time, Nov. 11), after spending 166 days in space.
The crew brought with them an Olympic torch which was launched to the station Nov. 6 and taken on a spacewalk Saturday as part of the torch relay. The torch was not lit in space, but will be used to light the Olympic flame at the Fisht Stadium in Sochi, Russia, at the start of the 2014 Winter Games in February.
Nyberg, Parmitano and Yurchikhin arrived at the station in May, and during their extended stay in space orbited Earth 2,656 times and traveled more than 112 million km (70 million miles). Parmitano conducted a spacewalk in July, becoming the first Italian to walk in space.
The crew will undergo post-landing medical evaluations and then return to their respective countries.

ESA’s GOCE satellite has reentered Earth’s atmosphere, with most of the spacecraft disintegrating high in the atmosphere. There have been no reports of damage to property or sightings of debris. Astrophysicist and satellite watcher Jonathan McDowell reported that the spacecraft came down at approximately 00:16 UTC on November 11, 2013 over the South Atlantic Ocean east of Tierra del Fuego – an archipelago off the southernmost tip of the South America.
The last visible sighting of GOCE was at 22:42 UTC on Nov. 10 as it passed 121km (75 miles) above Antarctica, BBC reported.
While most of the 1100 kg satellite disintegrated in the atmosphere, an estimated 25% reached Earth’s surface, likely falling in the ocean.
“The one-ton GOCE satellite is only a small fraction of the 100–150 tons of man-made space objects that reenter Earth’s atmosphere annually,” said Heiner Klinkrad, Head of ESA’s Space Debris Office. “In the 56 years of spaceflight, some 15,000 tons of man-made space objects have reentered the atmosphere without causing a single human injury to date.”
The GOCE spacecraft was designed to fly low and has spent most of its mission roughly 500 km below most other Earth-observing missions, at an altitude of 255 km (158 miles), but has recently been at the lowest altitude of any research satellite at 224 km (139 miles).
Its durable construction and sleek design allowed it to stay in space for longer than expected; it nearly tripled its planned lifetime.
With GOCE data, scientists created the first global high-resolution map of the boundary between Earth’s crust and mantle – called the Moho – and to detect sound waves from the massive earthquake that hit Japan on 11 March 2011, among other results.

NASA GODDARD SPACE FLIGHT CENTER, MARYLAND – Super Typhoon Haiyan smashed into the island nation of the Philippines, Friday, Nov. 8, with maximum sustained winds estimated at exceeding 195 MPH (315 kilometer per hour) by the U.S. Navy Joint Typhoon Warning Center – leaving an enormous region of catastrophic death and destruction in its terrible wake.
The Red Cross estimates over 1200 deaths so far. The final toll could be significantly higher. Local media reports today say bodies of men, women and children are now washing on shore.
The enormous scale of Super Typhoon Haiyan can be vividly seen in space imagery captured by NASA, ISRO and Russian satellites – as well as astronaut Karen Nyberg flying overhead on board the International Space Station (ISS); collected here.

Super Typhoon Haiyan is reported to be the largest and most powerful storm ever to make landfall in recorded human history.
Haiyan is classified as a Category 5 monster storm on the U.S. Saffir-Simpson scale.
It struck the central Philippines municipality of Guiuan at the southern tip of the province of Eastern Samar early Friday morning Nov. 8 at 20:45 UTC (4:45 am local time).
As Haiyan hit the central Philippines, NASA says wind gusts exceeded 235 mph (379 kilometers per hour).
The high resolution imagery and precise measurements provided by the worlds constellation of Earth observing space satellites (including NASA, Roscosmos, ISRO, ESA, JAXA) are absolutely essential to tracking killer storms and providing significant advance warning to evacuate residents in affected areas to help minimize the death toll and damage.
More than 800,000 people were evacuated. The storm surge caused waves exceeding 30 feet (10 meters), mudslides and flash flooding.
NASA’s Tropical Rainfall Measuring Mission (TRMM) satellite captured visible, microwave and infrared data on the storm just as it was crossing the island of Leyte in the central Philippines, reports NASA – see image below.

TRMM data from rain rates are measured by the TRMM Precipitation Radar (PR) and TRMM Microwave Imager (TMI) and combined with infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS) by science teams working at NASA’s Goddard Space Flight Center in Greenbelt, Md.
Coincidentally NASA Goddard has just completed assembly of the next generation weather satellite Global Precipitation Measurement (GPM) observatory that replaces TRMM – and where I inspected the GPM satellite inside the Goddard clean room on Friday.
“GPM is a direct follow-up to NASA’s currently orbiting TRMM satellite,” Art Azarbarzin, GPM project manager, told Universe Today during my exclusive clean room inspection of the huge GPM satellite.

“TRMM is reaching the end of its usable lifetime. GPM launches in February 2014 and we hope it has some overlap with observations from TRMM.”
“The Global Precipitation Measurement (GPM) observatory will provide high resolution global measurements of rain and snow every 3 hours,” Dalia Kirschbaum, GPM research scientist, told me at Goddard.
GPM is equipped with advanced, higher resolution radar instruments. It is vital to continuing the TRMM measurements and will help provide improved forecasts and advance warning of extreme super storms like Hurricane Sandy and Super Typhoon Haiyan, Azarbarzin and Kirschbaum explained.

The full magnitude of Haiyan’s destruction is just starting to be assessed as rescue teams reach the devastated areas where winds wantonly ripped apart homes, farms, factories, buildings and structures of every imaginable type vital to everyday human existence.
Typhoon Haiyan is moving westward and is expected to forcefully strike central Vietnam in a day or two. Mass evacuations are underway at this time

The Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite has been orbiting Earth in super-low orbits since 2009, mapping out variations in Earth’s gravity in extreme detail. But its fuel ran out in mid-October and the satellite began its slow descent towards Earth, being brought lower and lower by the effects of the atmosphere. Engineers predict it will re-enter completely and fall back to Earth sometime this weekend.
But no one can say for sure when or where the 1-ton satellite will fall.
With no remaining fuel to guide its re-entry there’s no way to nudge or steer its descent. And while most of GOCE is predicted to disintegrate in the atmosphere, several parts might reach Earth’s surface. Experts predict as much as 25% of the spacecraft will survive reentry, as many parts are made of advanced materials, such as carbon-carbon composites.
Today, engineers from the GOCE mission said that the spacecraft is predicted to enter into Earth’s atmosphere sometime during the night between Sunday and Monday, November 10-11, 2013. Break-up of the spacecraft will occur at an altitude of approximately 80 km. “At the moment, the exact time and location of where the fragments will land cannot be foreseen,” says ESA.
The GOCE spacecraft was designed to fly low and has spent most of its mission roughly 500 km below most other Earth-observing missions, at an altitude of 255 km (158 miles), but has recently been at the lowest altitude of any research satellite at 224 km (139 miles).
Its durable construction and sleek design allowed it to stay in space for longer than expected; it nearly tripled its planned lifetime.
With GOCE data, scientists created the first global high-resolution map of the boundary between Earth’s crust and mantle – called the Moho – and to detect sound waves from the massive earthquake that hit Japan on 11 March 2011, among other results.
Heiner Klinkrad, Head of ESA’s Space Debris Office at ESOC, Darmstadt, Germany said that when the spacecraft reaches altitudes below 100 km, then atmospheric density will drastically increase on the spacecraft. It will enter at about 25,000 km/hour, and aerodynamic pressure and heating will cause a break-up of the spacecraft at approximately 80km altitude, causing a large number of fragments.
“The risk to the population on ground will be minute,” said Klinkrad. “Statistically speaking, it is 250,000 times more probable to win the jackpot in the German Lotto than to get hit by a GOCE fragment. In 56 years of space flight, no man-made space objects that have re-entered into Earth’s atmosphere have ever caused injury to humans.”
An international campaign will be monitoring the descent, involving the Inter-Agency Space Debris Coordination Committee. The situation is being continuously watched by ESA’s Space Debris Office, which will issue re-entry predictions and risk assessments.
ESA says they will keep the relevant safety authorities permanently updated.

The Sun is finally acting like it’s in solar maximum. Our Sun has emitted dozens of solar flares in since Oct. 23, 2013, with at least six big X-class flares. Just today it blasted out a X1.1 flare at 04:32 UT (11:32 p.m. EST on Nov. 7, 2013). While old Sol had been fairly quiet for the time where it was supposed to be active in its normal 11-year cycle, only recently has activity ramped up with increased flares and sunspots. During 2013, there has been intermittent strong activity (like this and this in May), but the activity since mid-October is really the first extended period of activity.
Speaking of sunspots, a huge group called designated as AR 1890 has turned to face Earth. Thanks to astrophotographer Ron Cottrell for capturing the group today, above. Spaceweather.com reports that this sunspot has a trend of producing very brief flares. The X1-flare today was no exception as it lasted barely a minute. NOAA is forecasting a 60% chance of M-class solar flares and a 20% chance of X-flares on Nov. 8th from this sunspot group.
You can see an image from the Solar Dynamics Observatory below, as it recorded a flash of extreme UV radiation from the blast site:

NASA describes a solar flare as such:
A flare is defined as a sudden, rapid, and intense variation in brightness. A solar flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released. Radiation is emitted across virtually the entire electromagnetic spectrum, from radio waves at the long wavelength end, through optical emission to x-rays and gamma rays at the short wavelength end. The amount of energy released is the equivalent of millions of 100-megaton hydrogen bombs exploding at the same time.
While solar flares are powerful bursts of radiation, harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. But when they are intense enough, they can disturb the atmosphere in the layer where GPS and communications signals travel.

In true Richard Branson flair, the founder of Virgin Galactic has a multimedia plan in place for when he and his adult children, Holly and Sam, take the first planned tourist spaceflight next year. Virgin Galactic and NBCUniversal signed a “multi-platform partnership” for the network’s affiliates to transmit the flight all over the place.
Disclosed platforms so far include CNBC, MSNBC, NBCNews.com, Syfy and The Weather Channel. They also plan a “primetime special” on NBC on the launch’s eve, and to host a live event for three hours on NBC’s Today show. Financial terms were not released.
“Virgin Galactic is thrilled that NBCUniversal will join us on our exciting first journey to space,” stated Branson. “In this first chapter of commercial space travel, we will help make space accessible and inspire countless more people to join us in the pursuit of space exploration and science innovation.”
Virgin’s SpaceShipTwo is in the midst of powered flight tests and the company has hundreds of people signed up for flights. The company is one of several American contenders to run space tourism flights regularly, with XCOR Aerospace and Amazon founder Jeff Bezos’ Blue Origin among the most cited competitors.

Things are a little more crowded than usual in the International Space Station. For a few days, nine astronauts and cosmonauts are floating in the cramped quarters of the orbiting complex. Typical crew sizes range between three and six. How did the astronauts find room to work and sleep?
“One of the things we had to do was make space for them,” said European Space Agency astronaut Luca Parmitano in a rare press conference today (Nov. 8) from orbit, which included participation from Universe Today. He then explained a procedure where the astronauts swapped a Soyuz crew spacecraft from one Russian docking port to another a few days before Expedition 38/39’s crew arrived on board on Thursday. This cleared the way for three more people to arrive.
“We [also] had to adjust for emergency procedures. All of our procedures are trained and worked for a group of six. We had to work on a way to respond if something happened.” As for sleeping, it was decided the six people already on board, “as seniority, would stay in the crew quarters.” The newer astronauts have temporary sleeping arrangements in other modules until the ranks thin out a bit on Sunday.
So this works for a short while, but what about the long-term? Could the station handle having nine people there for weeks at a time, rather than six, and would there be enough science work to go around?

“I think, absolutely, moving to nine people is doable and in terms of the science would be fantastic,” NASA astronaut Karen Nyberg said. The station partners had experience with increasing crews before, she added, as for several years a regular space station rotation was only three astronauts during construction. Bumping up to the current maximum of six was a “big jump.”
“One of the things to be concerned about our environmental control system, our CO2 [carbon dioxide scrubbing] system … and also the consumables and the supplies we need,” she added. “Making up the science for us to do would be very doable. I think the hard part would be getting the systems to accommodate nine people.”
Parmitano, Nyberg and Russian cosmonaut Fyodor Yurchikhin plan to return to Earth Sunday, but a busy weekend lies ahead. On Saturday, Roscosmos (Russian Federal Space Agency) flight engineers Oleg Kotov and Sergey Ryazanskiy of the Russian Federal Space Agency will start a spacewalk around 9:30 a.m. EST (2:30 p.m. UTC) if all goes to plan.

As part of the Olympic torch relay ahead of the Sochi games in 2014, they will briefly bring the Olympic torch outside with them, unlit, before doing some outside maintenance.
“After the photo opportunity, Kotov and Ryazanskiy will prepare a pointing platform on the hull of the station’s Zvezda service module for the installation of a high resolution camera system in December, relocate … a foot restraint for use on future spacewalks and deactivate an experiment package,” NASA stated in a Thursday press release.
Several journalists were unable to ask questions during the NASA portion of the press conference, which included participation from countries covered by NASA, the European Space Agency, the Japanese Aerospace Exploration Agency and Roscosmos (the Russian Federal Space Agency).
“We had a failure in a crucial component in the phone bridge,” NASA spokesman Kelly Humphries told Universe Today following the media event. They don’t know what component failed, but most of the journalists were unable to hear the moderator or the astronauts.
“A piece of equipment picked the wrong time to fail,” Humphries said
NASA will do a thorough investigation before holding another event like this to make sure it works for everyone.
