[/caption]A beautiful and peaceful Christmas-time picture of The Strait of Hormuz was shot from the International Space Station (ISS) soaring some 250 miles (400 kilometers) overhead on Christmas Eve, 24 Dec 2011.
Today, the economically vital Strait of Hormuz is a ‘Flashpoint of Tension’ between Iran and the US and much of the rest of the world community because of official threats by Iranian government officials to shut the highly strategic waterway to crude oil tankers that transport the lifeblood of the world’s economy.
The timely image above was just tweeted by NASA Astronaut Ron Garan who wrote; “Interesting peaceful pic of the #StraightofHormuz #FromSpace taken on Christmas Eve (12/24/11) from the #ISS”. Garan served aboard the ISS from April to September 2011 as a member of the Expedition 27/28 crews.
The Strait of Hormuz lies at the mouth of the Persian Gulf between Iran and the Arabian Peninsula and is a major chokehold of the world’s energy consumption.
At its narrowest point, the Strait is only 34 miles (54 kilometers) wide. The vital shipping lanes span barely 2 miles (3 kilometers) in width in each direction (see maps below).
See more ISS photos of the Persian Gulf region and the Strait, below.
Each and every day, about 20% of the world’s daily petroleum consumption is shipped through the extremely narrow channel on gigantic Oil tankers. Any disruption of petroleum shipments would instantly send crude oil prices skyrocketing to exhorbitant levels that could wreak havoc and rapidly lead to a worldwide economic depression and a devastating war between Iran and the US and its allies.
In recent days Iranian boats have approached US Naval warships at high speeds while they were heading through the Strait of Hormuz – playing a potentially deadly game of cat and mouse that could spin out of control in a single misstep, even if unintentional.
Clashes would easily disrupt the crude oil tanker shipping traffic.
Several Iranian speedboats came within about 800 yards of the US vessels in recent days as a war of words has flared over oil and Iran’s nuclear program as tensions escalate.

The US and allied fleet operates in the Gulf region to protect the oil shipments and the oil installations of a number of Arab countries including Saudi Arabia.

SpaceX’s Dragon spacecraft has gotten its wings and is set to soar to the International Space Station (ISS) in about a month. NASA and SpaceX are currently targeting a liftoff on Feb. 7 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
Dragon is a commercially developed unmanned cargo vessel constructed by SpaceX under a $1.6 Billion contract with NASA. The Dragon spacecraft will launch atop a Falcon 9 booster rocket also built by SpaceX, or Space Exploration Technologies.
The Feb. 7 demonstration flight – dubbed COTS 2/3 – represents the first test of NASA’s new strategy to resupply the ISS with privately developed rockets and cargo carriers under the Commercial Orbital Transportation Services (COTS) initiative.
Following the forced retirement of the Space Shuttle after Atlantis final flight in July 2011, NASA has no choice but to rely on private companies to loft virtually all of the US share of supplies and equipment to the ISS.
The Feb. 7 flight will be the first Dragon mission actually tasked to dock to the ISS and is also the first time that the Dragon will fly with deployable solar arrays. The twin arrays are the primary power source for the Dragon. They will be deployed a few minutes after launch, following Dragon separation from the Falcon 9 second stage.
The solar arrays can generate up to 5000 watts of power on a long term basis to run the sensors and communications systems, drive the heating and cooling systems and recharge the battery pack.
SpaceX designed, developed and manufactured the solar arrays in house with their own team of engineers. As with all space hardware, the arrays have been rigorously tested for hundreds of hours under the utterly harsh conditions that simulate the unforgiving environment of outer space, including thermal, vacuum, vibration, structural and electrical testing.
The two arrays were then shipped to Florida and have been attached to the side of the Dragon’s bottom trunk at SpaceX’s Cape Canaveral launch processing facilities. They are housed behind protective shielding until commanded to deploy in flight.

I’ve toured the SpaceX facilities several times and seen the Falcon 9 and Dragon capsule launching on Feb. 7. The young age and enthusiasm of the employees is impressive and quite evident.
NASA recently granted SpaceX the permission to combine the next two COTS demonstration flights into one mission and dock the Dragon at the ISS if all the rendezvous practice activities in the vicinity of the ISS are completed flawlessly.
The ISS crew is eagerly anticipating the arrival of Dragon, for whch they have long trained.
“We’re very excited about it,” said ISS Commander Dan Burbank in a televised interview from on board the ISS earlier this week.
The ISS crew will grapple the Dragon with the station’s robotic arm when it comes within reach and berth it to the Earth-facing port of the Harmony node.
“From the standpoint of a pilot it is a fun, interesting, very dynamic activity and we are very much looking forward to it,” Burbank said. “It is the start of a new era, having commercial vehicles that come to Station.”
Burbank is a US astronaut and captured stunning images of Comet Lovejoy from the ISS just before Christmas, collected here.

Has the International Space Station (ISS) secretly joined NASA’s newly arrived GRAIL lunar twins orbiting the Moon?
No – but you might think so gazing at these dazzling new images of the Moon and the ISS snapped by a NASA photographer yesterday (Jan. 4) operating from the Johnson Space Center in Houston, Texas.
Check out this remarkable series of NASA photos above and below showing the ISS and her crew of six humans crossing the face of Earth’s Moon above the skies over Houston, Texas. And see my shot below of the Moon near Jupiter – in conjunction- taken just after the two GRAIL spacecraft achieved lunar orbit on New Year’s weekend.
In the photo above, the ISS is visible at the upper left during the early evening of Jan. 4, and almost looks like it’s in orbit around the Moon. In fact the ISS is still circling about 248 miles (391 kilometers) above Earth with the multinational Expedition 30 crew of astronauts and cosmonauts hailing from the US, Russia and Holland.
The amazing photo here is a composite image showing the ISS transiting the Moon’s near side above Houston in the evening hours of Jan 4.
The ISS is the brightest object in the night sky and easily visible to the naked eye if it’s in sight.
With a pair of binoculars, it’s even possible to see some of the stations structure like the solar panels, truss segments and modules.
Check this NASA Website for ISS viewing in your area.
How many of you have witnessed a sighting of the ISS?
It’s a very cool experience !
NASA says that some especially good and long views of the ISS lasting up to 6 minutes may be possible in the central time zone on Friday, Jan 6 – depending on the weather and your location.
And don’t forget to check out the spectacular photos of Comet Lovejoy recently shot by Expedition 30 Commander Dan Burbank aboard the ISS – through the Darth Vader like Cupola dome, and collected here
Make or break time for NASA’s big bet on commercial space transportation is at last in view. NASA has announced Feb. 7, 2012 as the launch target date for the first attempt by SpaceX to dock the firms Dragon cargo resupply spacecraft to the International Space Station (ISS), pending final safety reviews.
The Feb. 7 flight will be the second of the so-called Commercial Orbital Transportation Services (COTS) demonstration flights to be conducted by Space Exploration Technologies, or SpaceX, under a contact with NASA.
Several months ago SpaceX had requested that the objectives of the next two COTS flights, known as COTS 2 and COTS 3, be merged into one very ambitious flight and allow the Dragon vehicle to actually dock at the ISS instead of only accomplishing a rendezvous test on the next flight and waiting until the third COTS flight to carry out the final docking attempt.
The Dragon will remain attached to the ISS for about one week and astronauts will unload the cargo. Then the spacecraft will depart, re-enter the Earth atmosphere splashdown in the Pacific Ocean off the coast of California.
“The cargo is hundreds of pounds of astronaut provisions,” SpaceX spokeswoman Kirstin Grantham told Universe Today.
“SpaceX has made incredible progress over the last several months preparing Dragon for its mission to the space station,” said William Gerstenmaier, NASA’s associate administrator for the Human Exploration and Operations Mission Directorate. “We look forward to a successful mission, which will open up a new era in commercial cargo delivery for this international orbiting laboratory.”
Since the forced retirement of NASA’s Space Shuttle following the final fight with orbiter Atlantis in July 2011 on the STS-135 mission, the US has had absolutely zero capability to launch either supplies or human crews to the massive orbiting complex, which is composed primarily of US components.
In a NASA statement, Gerstenmaier added, “There is still a significant amount of critical work to be completed before launch, but the teams have a sound plan to complete it and are prepared for unexpected challenges. As with all launches, we will adjust the launch date as needed to gain sufficient understanding of test and analysis results to ensure safety and mission success.”
SpaceX lofted the COTS 1 flight a year ago on Dec. 8, 2010 and became the first private company to successfully launch and return a spacecraft from Earth orbit. SpaceX assembled both the Falcon 9 booster rocket and the Dragon cargo vessel from US built components.
The new demonstration flight is now dubbed COTS 2/3. The objectives include Dragon safely demonstrating all COTS 2 operations in the vicinity of the ISS by conducting check out procedures and a series of rendezvous operations at a distance of approximately two miles and the ability to abort if necessary.
The European ATV and Japanese HTV cargo vessels carried out a similar series of tests during their respective first flights.
After accomplishing all the rendezvous tasks, Dragon will then receive approval to begin the COTS 3 activities, gradually approaching the ISS from below to within a few meters.
Specially trained astronauts working in the Cupola will then reach out and grapple Dragon with the Station’s robotic arm and then maneuver it carefully into place onto the Earth-facing side of the Harmony node. The operations are expected to take several hours.
If successful, the Feb. 7 SpaceX demonstration flight will become the first commercial mission to visit the ISS and vindicate the advocates of commercial space transportation who contend that allowing private companies to compete for contracts to provide cargo delivery services to the ISS will result in dramatically reduced costs and risks and increased efficiencies.
The new commercial paradigm would also thereby allow NASA to focus more of its scarce funds on research activities to come up with the next breakthroughs enabling bolder missions to deep space.
If the flight fails, then the future of the ISS could be in serious jeopardy in the medium to long term because there would not be sufficient alternative launch cargo capacity to maintain the research and living requirements for a full crew complement of six residents aboard the orbiting laboratory.
Feb. 7 represents nothing less than ‘High Stakes on the High Frontier’.
NASA is all about bold objectives in space exploration in both the manned and robotic arenas – and that’s perfectly represented by the agencies huge gamble with the commercial cargo and commercial crew initiatives.
A Russian Soyuz capsule carrying the first crew of humans to fly to space in the post Space Shuttle Era has successfully docked at the International Space Station early this morning, Nov. 16 at 12:24 a.m. EST, averting the potential of having to at least temporarily abandon the massive Earth orbiting research complex.
After an 11 year stretch of continuous human occupation, the future residency of humans aboard the ISS swung in the balance in the wake of a Russian Soyuz rocket failure in August that temporarily grounded all Soyuz launches – manned and unmanned – until the root cause was determined and satisfactorily rectified with NASA’s consent.
The very survival of the ISS hinged on the successful launch of a trio of Russian and American space flyers just 2 days ago from the Baikonur Cosmodrome in Kazahkstan aboard the Soyuz TMA-22 capsule, which took place amidst an unprecedented blizzard and white out conditions with near zero visibility.
The three man crew of Russian rookie cosmonauts Anton Shkaplerov and Anatoly Ivanishin along with veteran NASA astronaut Dan Burbank arrived at the Poisk module of the orbiting outpost just in the nick of time – before the last three ISS crewmembers still aboard would have been forced to depart just 5 days from today leaving no humans aboard.
Luckily the Soyuz launch and automated rendezvous and linkup with the ISS flying some 400 km (248 miles) above the South Pacific proceeded flawlessly, announced Russian space officials at Mission Control in Moscow shortly after the successful docking. The event was carried live on NASA TV.
A full complement of 6 crew members was thus restored to the ISS, but the handover period will be exceedingly short because the Soyuz TMA-22 launch was postponed from September 22 due to the Soyuz rocket failure in August carrying the unmanned Progress cargo resupply vessel.
The new trio joins the current Expedition 29 residents comprising ISS Commander Mike Fossum (NASA) and Flight Engineers Satoshi Furukawa (Japan) and Sergei Volkov (Russia). But Fossum, Furukawa and Volkov will depart on Monday, Nov. 21, and thereby reduce the station crew population back down to three.
“The crew will have a very busy time during the short handover period,” said William Gerstenmaier, NASA Associate Administrator for the Human Exploration and Operation Directorate, who was present in Moscow.
“I want to thank our Russian colleagues for a tremendous job. It’s great to have six people back aboard the ISS,” Gerstenmaier said.
The newly arrived crew is expected to stay at the ISS for about five months and carry out a wide range of science experiments.
After closing the hooks and latches, removing the docking probe and conducting extensive pressure and leak checks, Shkaplerov, Ivanishin and Burbank opened the hatches and floated into the ISS to join their awaiting friends friends with a big round of bear hugs and greetings at about 2:39 a.m. EST today, Nov 16.
“Its great to see all six of you together up there,” radioed Gerstenmaier after the hatch opening.
“It’s was a great ride uphill and it will be a great stay up here,” Burbank replied.
The cosmonauts children exuberantly said “Hi , how are you. Kisses to you Daddy !” to their dads in space moments later !
The next three man Soyuz crew of US astronaut Don Pettit, Dutch astronaut André Kuipers, and Russian cosmonaut Oleg Kononenko, is set to arrive on December 23 and again restore the crew to a full complement of six.
The future survival and fate of the International Space Station was on the line and is now firmly back on track following today’s (Nov. 13) successful, high stakes liftoff of a Russian Soyuz rocket carrying a three man crew of two Russians and one American bound for the orbiting research platform, amidst the backdrop of a spectacular snowstorm swirling about the Baikonur Cosmodrome in Kazakhstan – rare even by Russian standards.
The international crew comprises Expedition 29 Flight Engineer Dan Burbank from NASA – veteran of two prior shuttle missions to the station in 2000 and 2006 – and Anton Shkaplerov and Anatoly Ivanishin from Russia. It’s the rookie flight for both Russian cosmonauts.
This is the first flight of a manned Soyuz-FG rocket – and of humans to space – since NASA’s Space Shuttle was forcibly retired in July and the subsequent failure of a virtually identical unmanned Soyuz-U booster in August which grounded all Russian flights to the ISS and threatened to potentially leave the station with no human presence aboard.
The trio of space flyers soared to the heavens at 11:14:03 p.m. EST Sunday Nov. 13 (11:14:03 a.m. Baikonur time Monday, Nov. 14) abroad their Soyuz TMA-22 capsule which was mounted atop the 50 meter tall Soyuz rocket.
Blastoff occurred precisely on time at about the time when the frigid, snow bedecked launch pad rotated into the plane of the orbit of the ISS. The launch was carried live on NASA TV and the ship quickly disappeared from view behind the nearly blinging blizzard.
The Soyuz TMA-22 achieved orbital insertion some nine minutes later into an initial 143 by 118 mile orbit, inclined 51 degrees to the equator.
The vehicles antennae’s and solar arrays were quickly deployed per plan and all spacecraft systems were functioning perfectly according to Russian Ground Control in Moscow.
Following a two day orbital chase and three course correction burns the future ISS residents are due to dock at the Russian Poisk module at the complex at about 12:33 a.m. EST on Wednesday, Nov. 16.
In the hours prior to launch the crew received a religious blessing from the Russian Orthodox Church, took the bus for the 25 mile trip to the Cosmodrome, donned their white Sokol launch and entry suits and headed to the pad.
The crew boarded the capsule in the midst of an extremely heavy snow storm which struck the Baikonur region of Kazakhstan in the evening prior to launch. See photo from backup NASA astronaut Joe Acaba.
Although snow is quite common at this time of year, the blizzard conditions at launch time were actually quite rare according to NASA spokesman Rob Navias at Baikonur.
American rockets would never blast off in such severe weather conditions – but it’s nothing for the Russians!
The temperature was about 24 F, roughly 6 inches (15 cm) of snow had accumulated on the ground at launch time and moderate wind gusts partially obscured the view.
For the first time ever, a Soyuz crew was dressed in parkas – See Joe Acaba twitpic below !
Gantry towers were retracted from the three stage Soyuz booster at about T minus 25 minutes. The umbilical’s retracted in the final seconds.
The three stage Soyuz-FG rocket lifted off from Launch Pad 1 (LC-1), the same pad from which Cosmonaut Yuri Gagarin flew as the first human to space 50 Years ago this year. The pad is named “Gagarin Start” in honor of Gagarin’s courageous achievement on April 12, 1961.
The rocket was fueled with kerosene (RP-1) and cryogenic liquid oxygen.
The ISS was flying some 248 miles above the Pacific Ocean and just west of Chile at launch time.
The importance of the TMA-22 mission cannot be overstated because it restored confidence in Russian rockets which now serve as the world’s only pathway for providing human access to the $100 Billion earth orbiting outpost.
The cramped Soyuz capsule measures just 2.2 m wide by 2.1 m high and weighs 2200 kg.
Today’s critical launch had been delayed be nearly two months from September 22, following the failure of a nearly identical Soyuz-U booster in August which was carrying the Progress 44 cargo resupply spacecraft and crashed ignominiously in Siberia after the third stage shut down unexpectedly.
The Progress 44 was loaded with nearly 3 tons of supplies and was bound for the ISS.
The third stage is nearly identical for both the manned and unmanned versions of the normally highly reliable Soyuz booster rocket.
The launch came only after a thorough review of the causes of the accident by a special State Commision- which was traced to a clogged fuel line – introduction of new quality control measures and careful inspection of all the engines.
“We have no doubt in our minds both the rocket and the vehicle are ready, all the activities have been done at the appropriate level of quality and reliability,” said Vladimir Popovkin, Head of Roscosmos, the Russian Federal Space Agency, prior to liftoff.
The new crew will join the other half of Expedition 29 already in residence aboard the ISS; Expedition 29 Commander Mike Fossum (NASA) and Flight Engineers Satoshi Furukawa (Japan) and Sergei Volkov (Russia). This will temporarily restore the ISS to a full complement of 6 crewmembers – but only for a few days.
Fossum will hand over command of the station to the new crew within four days. His crew departs the ISS for Earth reentry on Nov. 21.
The successful launch means that the ISS will not have to be left unmanned for the first time since continuous manned occupation began over 11 years ago and which would have placed the station at risk in case of failures requiring human intervention.
Burbank, Shkaplerov and Ivanishin will spend 5 months aboard the station. They will be joined in December by the next trio to round out Expedition 30
The stakes could not be higher for the Russian Soyuz rocket now poised at the launch pad at Baikonur in Kazakhstan and which will loft the next trio of space flyers to the International Space Station on Sunday, Nov. 13. This is the first flight of a manned Soyuz rocket since the Space Shuttle was retired in July and the subsequent failure of an unmanned Soyuz booster in August of this year.
The booster was rolled out to the pad on Friday (Nov. 11) and the very fate of the Space Station and the partners $100 Billion investment hinges on a successful blastoff of the venerable Soyuz – which dates back to cosmonaut Yuri Gagarin and the inauguration of human spaceflight 50 years ago. This launch must succeed in order to keep a human presence aboard the ISS and comes in the wake of an upper stage failure days ago that left Russia’s ambitious Phobos-Grunt Mars mission stranded in Earth orbit and potentially doomed. See the Soyuz rollout video and pictures below

Following the August 24 launch failure and crash of a Soyuz rocket carrying the Progress 44 cargo resupply vehicle to the ISS, Russia’s manned space program was grounded because the third stage of the Soyuz rocket which malfunctioned is virtually identical for both the manned and unmanned versions.
Since NASA was forced to shut down the Space Shuttle program, the Russian Soyuz rocket and capsule are the sole method of transport to the ISS. Thus, American astronauts have no choice but to hitch a ride with the Russians.
No American replacement spacecraft will be ready for humans until 2014 at the very earliest. And significant NASA budget cuts are likely to delay the introduction of the proposed “space taxis” by several more years.
Liftoff off the three man crew aboard the Soyuz-TMA 22 capsule from the Baikonur Cosmodrome in Kazakhstan is slated for 11:14 p.m. EST Sunday Nov. 13 (11:14 a.m. Baikonur time Monday, Nov. 14) aboard the Soyuz TMA-22 spacecraft.
Originally, the launch of the Soyuz TMA-22 crew had been scheduled for September 22 but was immediately put on indefinite hold following the August 24 crash.
Russia promptly announced the formation of a special state commission to investigate the failure, which rapidly traced the malfunction to a clogged fuel line and instituted fixes and stricter quality control measures.
The international trio of new ISS residents consists of Expedition 29 Flight Engineer Dan Burbank from NASA and Anton Shkaplerov and Anatoly Ivanishin from Russia.
After a 2 day chase, they are due to link up with the ISS when their spacecraft docks to the Poisk mini-research module at 12:33 a.m. Wednesday.
When Burbank, Shkaplerov and Anatoly Ivanishin dock they will join the other trio of Expedition 29 crewmembers already aboard the ISS; Expedition 29 crewmates Commander Mike Fossum (NASA) and Flight Engineers Satoshi Furukawa (Japan) and Sergei Volkov (Russia) – and temporarily restore the ISS to a full complement of 6 crewmembers.
But the full ISS staffing will be short-lived, because Fossum, Furukawa and Volkov will hand over all ISS duties to the new crew and undock their Soyuz TMA-02M capsule from the Rassvet research module on Nov. 21 and depart for Earth reentry and landing in Kazakhstan hours later.
The new crew of three must reach the ISS before the current trio departs or the ISS would be left unmanned for the first time in over 11 years.
Astronauts had this view of the aurora on September 26, 2011. Credit: NASA
We’ve had some great views of the aurora submitted by readers this week, but this one taken from the International Space Station especially highlights the red color seen by many Earth-bound skywatchers, too. Karen Fox from the Goddard Space Flight Center says the colors of the aurora depend on which atoms are being excited by the solar storm. In most cases, the light comes when a charged particle sweeps in from the solar wind and collides with an oxygen atom in Earth’s atmosphere. This produces a green photon, so most aurora appear green. However, lower-energy oxygen collisions as well as collisions with nitrogen atoms can produce red photons — so sometimes aurora also show a red band as seen here.

Expedition 28 Soyuz Crew Lands Safely in Kazakhstan
The three man Soyuz TMA-21 crew of cosmonauts and astronauts comprising of Commander Alexander Samokutyaev, Expedition 28 commander Andrey Borisenko and NASA flight engineer Ronald Garan made a pinpoint landing following a flawless descent and touched down safely in the southern steppes of Kazakhstan at 12:00 AM EDT today, Sept. 16, (10 AM local time), thereby wrapping up a nearly six month tour of duty at the International Space Station.
The Soyuz capsule landed on its side as it is frequently wont to do, about three hours after sunrise. The soft landing engines fired within seconds of touchdown to cushion the shock.
A phalanx of twelve Russian search and recovery helicopters swooped in quickly after landing. The Russian forces had established two way communications and visual sighting with the space flyers in the last minutes of the descent.
Weather was perfect with very low winds, few clouds and warm temperatures of nearly 70 degrees Fahrenheit.
Altogether the trio spent 164 days in space, 162 of those were aboard the ISS. Their Soyuz capsule had docked at the ISS on April 7, 2011 following a two day trip after liftoff on April 5 from the Baikonur Cosmodome aboard a capsule dubbed Gagarin. The spaceship was named in honor of Yuri Gagarin, first human to orbit the Earth on the 50th anniversary of his courageous one orbit flight in April 1961 that inaugurated the Era of human spaceflight.
This crew lived aboard the ISS for the arrival of the final two history making flights of the Space Shuttle program as well as the anniversaries of Gagarin and America’s first astronaut in space, Alan Shepard.
The helicopter recovery team arrived at the Soyuz capsule with seconds of touchdown and began erection of an inflatable medical tent. The Soyuz was rolled to facilitate the safe and proper extraction of the crew.
The astronauts and cosmonauts were quickly extracted from the capsule by the ground crew, checked by doctors and placed in recliners for the two hour trip back to a staging base in Karaganda, Kazakhstan for a traditional Kazakh welcome. Thereafter the crew will split up. Garan will be returning immediately to the US on a flight back to the Mission Control in Houston, Texas.
Just hours earlier this evening, the trio bagan the process of departing the ISS. They donned their Sokol launch and entry pressure suits, floated into the return capsule and closed the hatches between the Soyuz and the ISS.
Following leak checks the crew unhooked latches and undocked the Soyuz from the Poisk module at 8:38 p.m. while flying over northern China. Three minutes later thrusters were fired for 15 seconds to separate the two vehicles.
Left behind on the station was the Expedition 29 crew comprising Commander Mike Fossum from the US, cosmonaut Sergei Volkov from Russia and Japanese astronaut Satoshi Furukawa.
As the ISS and Soyuz were flying in tandem, the crew executed the 4 minutes 14 sec “de-orbit burn” which took place exactly on time at 11: 05 p.m. EDT. The critical Soyuz thruster burn slowed the ship by some 258 MPH and enabled the capsule to drop out of orbit, setting up the descent down through the Earth’s atmosphere.
Then the computer commanded pyrotechnic separation of the three Soyuz modules took place some 87 miles above Earth about 22 minutes later at 11:33 p.m., occurring just three minutes prior to re-entry into the Earth’s atmosphere over the heart of Africa.
The crew landed inside the central descent module less than an hour after completing the burn and less than 30 minutes after module separation.
The ISS will now be tended by only a three man crew for the next two months. That’s an unusually long time to maintain a reduced crew. But it’s all due to the recent failure of the third stage of the Russian Soyuz-U rocket lofting the Progress 44 cargo ship on Aug 24. The failure has been traced to a clogged fuel line. Russia is working to determine exactly how and why this could have happened and taking steps to prevent a repeat which would have disastrous consequences.
The next Soyuz blastoff is provisionally set for Nov.14 with a station arrival on Nov. 16. The three man crew of Anton Shkaplerov, Anatoly Ivanishin and NASA flight engineer Dan Burbank had originally been slated for Sept 22. But it was pushed back following the Progress launch failure.
Mike Fossom’s crew is scheduled to depart just 2 days later. Thus any further Soyuz launch delay wil require the ISS to be at least temporarily “de-manned” for the first time since continuous crewed operations started a dozen years ago.
