If you’re a frequent reader of Universe Today you know that, despite the end of the Shuttle program and the constant battle for a piece of the federal budget, NASA has a lot on their plate for future space exploration missions. But there are still a lot of people among the general public who think that the U.S. space administration is “dead,” or, at the very least, in the process of dying. Which is unfortunate because there’s actually a lot going on, both in space and in development on the ground.
The video above, released Monday by Johnson Space Center, shows highlights from 2013 as well as some of the many things NASA has in progress. As anyone can see, rumors of its death have been greatly exaggerated! (By whom I’m still not quite sure.)
Visit the Johnson Space Center site for more information and updates on current and future missions.
UPDATE: Orbital announced the Antares launch today (Jan. 8) has been scrubbed because of solar activity. More info on the issue and a new launch date will be forthcoming.
Update: NASA and Orbital have set Thursday, Jan. 9 as the new Antares launch date. Liftoff is targeted for 1:07 p.m. (EST) Watch the launch live, below.
WALLOPS ISLAND, VA – Launch managers gave the “GO” for launch of the private Antares/Cygnus rocket to the space station on Wednesday, Jan. 8, even as the polar vortex swept in bone chilling cold to the launch site on the Virginia shore and across much of the United States.
At a launch readiness review today (Jan. 7), managers for spacecraft builder Orbital Sciences approved the launch, pending completion of a few remaining items, said Mike Pinkston, Antares program director for Orbital, at a media briefing today.
The commercial Antares rocket is launching the Cygnus cargo spacecraft on its first operational mission bound for the International Space Station (ISS) with a huge bounty of science experiments.
Blastoff is slated for 1:32 p.m. EST from Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops, Virginia.
There is only a 5 minute launch window that extends to 1:37 p.m.
The launch of the two stage, 133 foot tall Antares could put on a spectacular sky show.
Antares blastoff may be visible to millions of spectators up and down the US East Coast spanning from South Carolina to Massachusetts – weather permitting.
The Antares launch comes amidst the unprecedented, unrelenting and dangerous cold arctic air mass sweeping across the US.
Frigid, high winds buffeted the rocket and launch site all day today as technicians continued last minute preparations, taking care to insure safety for the rocket and themselves.
But tonight Antares and Cygnus were glistening beautifully under star lit skies during my up close visit to the launch pad.
The launch was originally scheduled for Tuesday, but was postponed a day to Wednesday because the rocket is only certified to lift off when the temperature is above 20 degrees Fahrenheit, said Frank Culberton, executive vice president and general manager of Orbital’s advanced spaceflight programs group.
Today’s temperatures at Wallops were only in the single digits and teens and felt much lower with the blustery conditions all day long.
Temperatures are expected to ‘skyrocket’ to the balmy 30’s on Wednesday.
There is a 95 percent chance of favorable weather at the time of launch, NASA said. High, thick clouds are the primary concern for a weather violation, but they are minor.
Both the Antares and Cygnus are private vehicles built by Orbital Sciences under a $1.9 Billion supply contract with NASA to deliver 20,000 kilograms of research experiments, crew provisions, spare parts and hardware to the ISS.
The flight is designated the Orbital-1, or Orb-1 mission.
Orbital Sciences commercial competitor, SpaceX, is likewise under contract with NASA to deliver 20,000 kg of supplies to the ISS with the SpaceX Falcon 9/Dragon architecture.
Both the Orbital Sciences Antares/Cygnus and SpaceX Falcon 9/Dragon vehicles were developed from the start with seed money from NASA in a public-private partnership.
A total of eight Antares/Cygnus missions to the space station are scheduled over the next two to three years by Orbital under its Commercial Resupply Services (CRS) contract with NASA.
This launch follows a pair of successful launches in 2013, including the initial test launch in April and the 1st demonstration launch to the ISS in September.
Cygnus is loaded with approximately 2,780 pounds / 1,261 kilograms of cargo for the ISS crew for NASA including science experiments, computer supplies, spacewalk tools, food, water, clothing and experimental hardware.
Among the research items packed aboard the Antares/Cygnus flight are an experiment to study the effectiveness of antibiotics in space and a batch of 23 student experiments involving life sciences topics ranging from amoeba reproduction to calcium in the bones to salamanders.
There is also an ant farm aboard with ant colonies from Colorado, North Carolina and of course host state Virginia too. The goal is to study ant behavior in space in zero gravity and compare that to ants on Earth living under normal gravity.
So you can watch the launch either with your own eyes, if possible, or via the NASA TV webcast.
NASA Television coverage of the Antares launch will begin at 1 p.m. on Jan. 8 – www.nasa.gov/ntv
A launch on either Jan. 8 or Jan. 9 will result in a grapple of Cygnus by the Expedition 38 crew aboard the station on Sunday, Jan. 12 at 6:02 a.m. EDT.
Watch for my ongoing Antares launch reports from on site at NASA Wallops.
Stay tuned here for Ken’s continuing Orbital Sciences, SpaceX, commercial space, Chang’e-3, LADEE, Mars and more news.
Orbital 1 Launch from NASA Wallops Island, VA on Jan. 8, 2014- Time of First Sighting Map
This map shows the rough time at which you can first expect to see Antares after it is launched on Jan. 8, 2014. It represents the time at which the rocket will reach 5 degrees above the horizon and varies depending on your location . We have selected 5 degrees as it is unlikely that you’ll be able to view the rocket when it is below 5 degrees due to buildings, vegetation, and other terrain features. As an example, using this map when observing from Washington, DC shows that Antares will reach 5 degrees above the horizon approximately 100 seconds after launch (L + 100 sec).

WALLOPS ISLAND, VA – Catching a slim weather break amidst the monster blizzard and unprecedented arctic air low temperatures afflicting the central and northern United States, Orbital Sciences Corp. is marching forward with plans for a spectacular daylight blastoff of the firms privately developed Antares rocket and Cygnus cargo spacecraft on Wednesday, Jan. 8 from a beachside pad at NASA Wallops Island, VA – on a critical mission for NASA bound for the Space Station carrying a huge cargo of vital science experiments.
Here’s our complete guide on “How to See the Antares/Cygnus Jan. 8 Blastoff” – chock full of viewing maps and trajectory graphics (above and below) from a variety of prime viewing locations; including historic landmarks in Washington, DC., NYC, Baltimore, Philadelphia, Virginia and more.
The cold weather, daytime Antares liftoff is currently scheduled for 1:32 p.m. EST from Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops, Virginia.
Due to continuing extremely cold weather conditions forecast for mid week, the launch could slip a day to Thursday, Jan. 9 when slightly warmer temperatures are expected, but it looks acceptable at this time.
This flight was originally due to blastoff at night in mid-December 2013 but was postponed due to the unexpected need for urgent repairs to get the stations critical cooling system restored to full operation following a malfunction. The fixes were accomplished during a pair of pre-Christmas spacewalks by American astronauts Rick Mastracchio and Mike Hopkins, paving the way for the Antares/Cygnus rescheduled liftoff.
And although it’s now moved to daylight due to orbital mechanics, the two stage Antares rockets exhaust plume should easily be visible to many millions of residents up and down the US East Coast spanning from South Carolina to Massachusetts – weather permitting.
Antares will be able to be seen by spectators inland as well, reaching potentially into portions of West Virginia, western Pennsylvania and New England depending on cloud cover.
For example; Here’s the expected view from the US Capitol – for all the politicians who decide NASA’s budget as well as myriads of tourists visiting from all across the globe.
The viewing maps are courtesy of Orbital Sciences, the private company that developed both the Antares rocket and Cygnus resupply vessel aimed at keeping the International Space Station (ISS) fully stocked and operational for science research.
Up top is the time of first sighting map showing when the rocket reaches 5 degrees of elevation in the eastern United States.
If you want to imitate Rocky’s famous workout on the steps of the Philadelphia Art Museum, here’s what you’ll see:
And with yet another cold arctic air mass gushing towards eastwards, its certain to be frigid in many regions – so be sure to dress warmly.
The flight is designated the Orbital-1, or Orb-1 mission.
Orb-1 is the first of eight commercial cargo resupply missions to the ISS by Orbital under its Commercial Resupply Services (CRS) contract with NASA.
This launch follows a pair of successful launches in 2013, including the initial test launch in April and the 1st demonstration launch to the ISS in September.
So here’s your chance to witness a mighty rocket launch – from the comfort of your home from locations along the east coast.
Best viewing of all will be in the mid-Atlantic region closest to Wallops Island.
If you have the opportunity to observe the launch locally, you’ll get a magnificent view and hear the rockets thunder at either the NASA Wallops Visitor Center or the Chincoteague National Wildlife Refuge/Assateague National Seashore.
For more information about the Wallops Visitors Center, including directions, see: http://www.nasa.gov/centers/wallops/visitorcenter
The rocket was rolled out to the Wallops launch pad on Sunday by Orbital’s technicians.
Cygnus is loaded with approximately 2,780 pounds / 1,261 kilograms of cargo for the ISS crew for NASA including science experiments, computer supplies, spacewalk tools, food, water, clothing and experimental hardware.
Among the research items packed aboard the Antares/Cygnus flight are an experiment to study the effectiveness of antibiotics in space and a batch of 23 student experiments involving life sciences topics ranging from amoeba reproduction to calcium in the bones to salamanders.
Of course you can still view the launch live via the NASA TV webcast.
NASA Television coverage of the Antares launch will begin at 1 p.m. on Jan. 8 – www.nasa.gov/ntv
A launch on either Jan. 8 or Jan. 9 will result in a grapple of Cygnus by the Expedition 38 crew aboard the station on Sunday, Jan. 12 at at 6:02 a.m. EDT.
Weather outlook appears rather promising at this time – 90% favorable chance of lift off.
Watch for my ongoing Antares launch reports from on site at NASA Wallops.

The status quo in space flight operations is no more.
Private American rockets are leading the charge of overdue change into the innovative ‘Commercial Space Race’ by blasting 2014 open with a pair of ‘Big Bang fireworks’ just a day apart on Jan. 6 and Jan. 7.
A dynamic duo of US aerospace firms – SpaceX and Orbital Sciences – are each poised to launch their own recently developed private boosters in the first week of the new year and aiming to dramatically cut costs.
And to top that off, the rockets are thundering aloft from two different spaceports located some 800 miles apart along the US East coast – weather permitting of course given the monster snow storm and frigid arctic air – akin to Mars – bearing down at this very moment on the big populations centers of the Atlantic coast region.
UPDATE ALERT – Antares Launch just postponed to Wed, Jan 8 at 1:32 p.m.due to extremely cold weather forecast. Back up day is Jan. 9
Both companies are revolutionizing access to space for both government entities as well as commercial companies doing lucrative business in space.
The implications of vastly reducing expenses for space travel and space commerce are far reaching and imperative – especially in the face of static and declining budgets mandated by politicians worldwide.
Except for China, which just landed its first rover on the Moon, is investing mightily in space and science and reaping strong economic growth.
SpaceX is first on deck with their next generation Falcon 9 rocket poised to soar on Monday, Jan. 6, with a highly valuable international payload – the Thiacom-6 commercial broadcasting satellite.
Note: This launch has just been postponed from Jan. 3 according to a brief statement I received from the USAF 45th Space Wing. Apparently due to concerns with the rocket – better safe than sorry.
Orbital Sciences follows up quickly on Tuesday, Jan. 7, with their two stage Antares rocket carrying the firm’s own Cygnus cargo vessel on its first operational commercial resupply mission for NASA – that’s bound for the International Space Station (ISS).
The upgraded SpaceX Falcon 9 v1.1 two stage rocket is slated to launch from complex 40 at Cape Canaveral Air Force Station, Florida, likely at dusk.
The original Jan. 3 Falcon 9 evening time launch had been scheduled for 5:50 p.m. Thaicom-6 will be placed into an elliptical supersynchronous transfer orbit.
The commercial space race sometimes makes for strange bedfellows. The Thaicom-6 satellite was built by Orbital Sciences.
This marks only the 2nd launch of the newly upgraded Falcon 9 from Florida. Read my eyewitness reports about the thunderous maiden liftoff barely a month ago on Dec. 3, 2013 with the SES-8 commercial telecom satellite – starting here.
The new Falcon 9 is the key to achieving SpaceX’s future launch manifest of some 50 payloads worth billions of dollars.
The next gen Falcon 9 will also launch the human rated SpaceX Dragon to the ISS. But first the Dragon and Falcon 9 must successfully achieve a pair of abort tests planned for 2014. Read my new article and discussion with SpaceX CEO Elon Musk – here.
The Jan. 7 Antares liftoff is currently scheduled for 1:55 p.m. EST from Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops Island, Virginia.
The Antares launch comes on the heels of the completely successful demonstration flight to the space station by Orbital Sciences in September 2013.
This flight was originally scheduled for mid-December 2013 in prime time but was postponed due to the urgent repairs required to get the ISS cooling system back in full operation.
And although it’s now moved to daylight by reason of orbital mechanics, the liftoff could still easily be visible to millions of residents along a wide swath of the US East Coast spanning from North Carolina to New York City – weather permitting.
I’ll be covering the Antares launch, dubbed Orb-1, from on site at NASA Wallops – watch for my continuing reports.
The Cygnus logistics vessel will carry a total of 2,780 pounds of supplies to the station, including vital science experiments to expand the research capability of the Expedition 38 crew members aboard the orbiting laboratory, crew provisions, spare parts and experiment hardware, says NASA.
Also packed aboard the Antares/Cygnus flight are a batch of student experiments involving life sciences topics ranging from amoeba reproduction to calcium in the bones to salamanders.
“The 23 experiments flying next week [on Antares/Cygnus] are the culmination of 8,700 students engaged in real experiment design, and 1,800 proposals received by student teams,” Dr. Jeff Goldstein told Universe Today. Goldstein is the Center Director for the National Center for Earth and Space Science Education (NCESSE),which is sponsoring and organizing the student experiments.
This rocket volley is but the opening salvo of shots heard reverberating round the world that will surely “rock” the space industry to its core by cutting the steep cost of access to space.
“This is really rocking the industry. Everybody has to look out,” said Martin Halliwell, SES chief technical officer during a recent media briefing with Elon Musk, including Universe Today.
Both the SpaceX Falcon 9/Dragon and Orbital Sciences Antares/Cygnus vehicles were developed from the start with seed money from NASA in a public-private partnership.
The goal was to restore America’s cargo and crew capabilities to low Earth orbit and the ISS that was totally lost following the forced retirement of NASA’s Space Shuttles.
After a slow start, both Orbital Sciences and SpaceX have succeeded in bringing their new rockets and delivery vehicles safely on line.
SpaceX next Dragon cargo launch to the ISS is currently scheduled for Feb. 22, said SpaceX spokeswoman Emily Shanklin to Universe Today.

CAPE CANAVERAL AIR FORCE STATION, FL – A trio of American companies – SpaceX, Boeing, and Sierra Nevada – are working diligently to restore America’s capability to launch humans into low Earth orbit from US soil, aided by seed money from NASA’s Commercial Crew Program in a public-private partnership.
We’ve been following the solid progress made by all three companies. Here we’ll focus on two crucial test flights planned by SpaceX in 2014 to human rate and launch the crewed version of their entry into the commercial crew ‘space taxi’ sweepstakes, namely the Dragon spacecraft.
Recently I had the opportunity to speak about the upcoming test flights with the head of SpaceX, Elon Musk.
So I asked Musk, the founder and CEO of SpaceX, about “what’s ahead in 2014”; specifically related to a pair of critical “abort tests” that he hopes to conduct with the human rated “version of our Dragon spacecraft.”
“Assuming all goes well, we expect to conduct [up to] two Dragon abort tests next year in 2014,” Musk told me.
The two abort flight tests in 2014 involve demonstrating the ability of the Dragon spacecraft abort system to lift an uncrewed spacecraft clear of a simulated launch emergency.
The crewed Dragon – also known as DragonRider – will be capable of lofting up to seven astronauts to the ISS and remaining docked for at least 180 days.
First a brief overview of the goals of NASA’s Commercial Crew Program. It was started in the wake of the retirement of NASA’s Space Shuttle program which flew its final human crews to the International Space Station (ISS) in mid-2011.
“NASA has tasked SpaceX, Boeing, and Sierra Nevada to develop spacecraft capable of safely transporting humans to the space station, returning that capability to the United States where it belongs,’ says NASA Administrator Charles Bolden.
Since 2011, US astronauts have been 100% dependent on the Russians and their Soyuz capsules to hitch a ride to low Earth orbit and the ISS.
The abort tests are essential for demonstrating that the Dragon vehicle will activate thrusters and separate in a split second from a potentially deadly exploding rocket fireball to save astronauts lives in the event of a real life emergency – either directly on the launch pad or in flight.
“We are aiming to do at least the pad abort test next year [in 2014] with version 2 of our Dragon spacecraft that would carry astronauts,” Musk told me.
SpaceX plans to launch the crewed Dragon atop the human rated version of their own developed Falcon 9 next generation rocket, which is also being simultaneously developed to achieve all of NASA’s human rating requirements.
The initial pad abort test will test the ability of the full-size Dragon to safely push away and escape in case of a failure of its Falcon 9 booster rocket in the moments around launch, right at the launch pad.
“The purpose of the pad abort test is to demonstrate Dragon has enough total impulse (thrust) to safely abort,” SpaceX spokeswoman Emily Shanklin informed me.
For that test, Dragon will use its pusher escape abort thrusters to lift the Dragon safely away from the failing rocket. The vehicle will be positioned on a structural facsimile of the Dragon trunk in which the actual Falcon 9/Dragon interfaces will be represented by mockups.
This test will be conducted on SpaceX’s launch pad 40 at Cape Canaveral Air Force Station in Florida. It will not include an actual Falcon 9 booster.
The second Dragon flight test involves simulating an in flight emergency abort scenario during ascent at high altitude at maximum aerodynamic pressure at about T plus 1 minute, to save astronauts lives. The pusher abort thrusters would propel the capsule and crew safely away from a failing Falcon 9 booster for a parachute assisted landing into the Atlantic Ocean.
“Assuming all goes well we expect to launch the high altitude abort test towards the end of next year,” Musk explained.
The second test will use the upgraded next generation version of the Falcon 9 that was successfully launched just weeks ago on its maiden mission from Cape Canaveral on Dec. 3. Read my earlier reports – starting here.
To date, SpaceX has already successfully launched the original cargo version of the Dragon a total of three times. And each one docked as planned at the ISS.
The last cargo Dragon blasted off on March 1, 2013. Read my prior articles starting – here.
The next cargo Dragon bound for the ISS is due to lift off on Feb. 22, 2014 from Cape Canaveral, FL.
Orbital Sciences – the commercial ISS cargo competitor to SpaceX – plans to launch its Cygnus cargo vehicle on the Orb-1 mission bound for the ISS on Jan. 7 atop the firms Antares rocket from NASA Wallops Flight Facility in Virginia. Watch for my on site reports from NASA Wallops.
NASA’s Commercial Crew Program’s goal is launching American astronauts from U.S. soil within the next four years – by 2017 to the ISS.
The 2017 launch date is dependent on funding from the US federal government that will enable each of the firms to accomplish a specified series of milestones. NASA payments are only made after each companies milestones are successfully achieved.
SpaceX was awarded $440 million in the third round of funding in the Commercial Crew integrated Capability (CCiCAP) initiative which runs through the third quarter of 2014. As of November 2013, NASA said SpaceX had accomplished 9 of 15 milestones and was on track to complete all on time.
Musk hopes to launch an initial Dragon orbital test flight with a human crew of SpaceX test pilots perhaps as early as sometime in 2015 – if funding and all else goes well.
Either a US commercial ‘space taxi’ or the Orion exploration capsule could have blasted off with American astronauts much sooner – if not for the continuing year-by-year slashes to NASA’s overall budget forced by the so called ‘political leaders’ of all parties in Washington, DC.
Stay tuned here for Ken’s continuing SpaceX, Orbital Sciences, commercial space, Chang’e-3, LADEE, Mars and more news.
Customers eager to watch live, high-definition images of Earth may have to wait a bit longer. Two Russian spacewalkers were unable to get two UrtheCast cameras to function despite spending eight hours and seven minutes outside yesterday (Dec. 27) — the longest spacewalk in Russian history.
The cause of the problem is not known. Oleg Kotov and Sergey Ryazanskiy followed all the steps as instructed, but controllers did not see telemetry or data flowing from the cameras as expected. The spacewalkers tried unplugging and replugging cables and other steps to fix the problem, but were eventually told to take some pictures of the equipment and then bring the cameras back inside for more analysis.
“So it appears we have seen an unsuccessful attempt at bringing those two cameras to life,”said Rob Navias, NASA’s Mission Control commentator, in live remarks published on CBS.
“The exact cause of the problem is not known at this point. The Russian flight control team will spend some time, obviously, analyzing the data and trying to understand from the analysis of these photographs whether or not the problem lies in the electrical connectors themselves or in the cameras, which of course would be a more significant issue.”
In remarks on Twitter, UrtheCast said it was preparing an official statement to release. ” ‘Tis the nature of space tech,” the British Columbia-based company said in response to a comment talking about the challenges of doing high-tech work in space. The company also made a comment to Reuters saying there was a problem with camera connectivity.
UrtheCast plans to use the two cameras to broadcast live views of the Earth to paying customers (particularly government and private agencies), while also serving as an educational platform for young students. The company is working directly with Russian aerospace giant RSC Energia and has no agreement with NASA for the work, according to this past Universe Today report.
The longest spacewalk in history took place on March 11, 2001 and took eight hours, 56 minutes. NASA astronauts Jim Voss and Susan Helms were doing work on the International Space Station during the record-setting jaunt.
This was the third spacewalk in a week on station. The other two were performed by Rick Mastracchio and Mike Hopkins, who replaced an ammonia pump needed to keep one of the station’s two cooling loops functioning. Experiments are gradually coming back online, NASA said, after the equipment spent two weeks in a forced shutdown.
For all you Earth observation geeks out there, we have some good news — two Russian astronauts are going to install a camera on Friday (Dec. 27) that will beam live images of Earth back to your browser.
The UrtheCast camera is the headline task for Expedition 38 astronauts Oleg Kotov and Sergey Ryazanskiy to perform, on top of installing a foot restraint and doing some equipment swapouts. This spacewalk, by the way, is not related in any way to the two successful contingency ones earlier this week to replace a faulty pump on station.
The spacewalk is supposed to start at 8 a.m. EST (1 p.m. UTC) and will be carried live on NASA Television, which you can view in the media player above or at this alternate link. The spacewalk is scheduled for seven hours, but could be longer or shorter as events arise.
“Imagine you have a nearly live Google Earth, but it isn’t four-year-old data – you have data that is being refreshed all the time, with videos coming down over interesting areas where interesting events are going on, showing you what is changing, what is going on,” said George Tyc, the chief technology officer at UrtheCast, in an interview with Universe Today earlier this year.
“What we really hope to pull off is to change the paradigm, get the everyday person interacting and seeing the data coming down from space to see the Earth and how it is evolving over time in a way that isn’t available right now.”
It’s been a busy week for spacewalkers on station as Rick Mastracchio and Mike Hopkins successfully replaced a pump that shut down two weeks ago and crippled one of the station’s two cooling loops for regulating the temperature of systems on station. With that work completed Tuesday (Dec. 24), a NASA update today (Dec. 26) said systems are slowly coming back online.
“Early on Christmas Day, the heat exchangers for the Destiny laboratory, the Harmony and Tranquility nodes and the Japanese Kibo laboratory were reintegrated to enable experiments racks and other systems affected by the partial Cooling Loop A shutdown Dec. 11 to come back on line,” NASA stated.
“The Columbus laboratory heat exchanger will remain down until the European Space Agency, at its own request, conducts that module’s integration next week when personnel return from the holiday.”
Toxic snowflakes in space were just one obstacle astronauts faced down today (Dec. 24) as they successfully replaced an ammonia pump that will, if all goes to plan, put the space station back in full service in a few hours.
“They’re just completely surrounding us now,” radioed NASA astronaut Rick Mastracchio of the ammonia flakes as the astronauts clipped four fluid lines into place on to the spare pump. NASA said the ammonia was just residual fluid and not indicative of a leak. “Some little ones, some big ones,” he added.
Within a few minutes, however, the ammonia dissipated. Some flakes did strike the spacesuits of Mastracchio and fellow NASA spacewalker Mike Hopkins, causing NASA to do a modified decontamination procedure where the astronauts stayed in a vacuum for a few extra minutes inside the airlock. (The sun’s heat bakes off ammonia over time, and the crew was outside long enough for most ammonia to dissipate, NASA said.)
The spacewalk completed with no further drama at 7 hours and 30 minutes, earning high praise for the participating astronauts from Mission Control in Houston.
“It’s the best Christmas ever,” radioed CapCom and NASA astronaut Doug Wheelock from the ground as the spacewalkers entered the International Space Station’s Quest airlock at the end of the repair job. “We got it,” Mastracchio responded.
Preliminary tests show the spare pump is working perfectly. The pump is a welcome present for the six-person Expedition 38 crew, which saw a reduction in science and backup systems for two weeks after a valve in the last pump failed, causing one of the station’s two cooling loops to shut down automatically. The loops are needed to regulate the temperatures of electronics and systems on station.
The Expedition 38 crew was so quick with the repair that they finished the job in two spacewalks instead of the planned three. The astronauts fell behind the timeline today as they struggled with some of the fluid connections to the new pump, but the final steps — putting the electrical connections in place — took just minutes. The pump was brought from another location on station today, and installed into its permanent spot to help ammonia flow through the cooling system.
Anywhere between hundreds and thousands of people at NASA and international partners scrambled to put spacewalks together to fix the cooling problem after it happened. Wheelock, himself a veteran of a tricky ammonia pump repair in 2010, communicated with the spacewalkers. Japanese astronaut Aki Hoshide filled the other CapCom slot, helping Japanese astronaut Koichi Wakata who handled robotics in orbit.
Mastracchio marked his eighth spacewalk with today’s repair while Hopkins, who rode Canadarm2 for the first time in a last-minute decision, was on his second. As with a spacewalk on Saturday (Dec. 21), the astronauts reported no helmet water leaks — comforting words for agency officials who put in new procedures and parts after an incident in July. (Mastracchio experienced a water problem during repressurization Saturday that was unrelated to the first incident, and wore a backup suit today to let the primary one dry out.)
Should the ammonia pump work as planned, this clears the way for the Russians to do a spacewalk Dec. 27 to install the Urthecast high-resolution camera that will beam live views of Earth, among other tasks. Expedition 38 has the day off tomorrow (Dec. 25), NASA TV added.
The only other Christmas Eve spacewalk in NASA history took place Dec. 24, 1999 during Hubble Space Telescope servicing mission STS-103. Another Christmas Eve milestone for NASA took place 45 years ago today, when the Apollo 8 crew made a now-famous broadcast while orbiting above the moon.
Two astronauts are oh-so-close to fixing the International Space Station cooling system that shut down Dec. 11. NASA astronauts Mike Hopkins and Rick Mastracchio will head “outside” on a spacewalk around 7:10 a.m. EST (12:10 p.m. UTC) to replace a faulty pump that led to the problem.
The spacewalkers were so quick on their first outing (on Saturday, Dec. 21) that they accomplished many of the tasks planned for their second spacewalk. They unhooked the first pump module and stowed it safely, then elected to wait until their second to retrieve the replacement pump, swap it in and turn it on.
Below the jump, here are some things to watch for — including why Hopkins is getting a ride on the Canadarm2 robotic arm this time instead of Mastracchio.
The suits. NASA has new safety procedures and measures in place to protect against helmet water leaks, and everything worked perfectly the first time. In an unrelated incident, while the astronauts were in the airlock, an inadvertent switch-throw introduced some water into Mastracchio’s sublimator. The suit is airing out and Mastracchio is wearing a backup suit. While sublimators need water to function, this water could have ended up in the wrong spot. If he had used the one with the water in it, it could have frozen during the second spacewalk and caused problems, Judd Frieling, the Expedition 38 lead flight director, explained on NASA TV Monday.
The background personnel. While it’s easy to shine the spotlight on the two guys outside, also remember that Japanese astronaut Koichi Wakata will be piloting the robotic arm under direction from CapCom and fellow Japanese astronaut Aki Hoshide. Giving advice to the spacewalkers will be CapCom and NASA astronaut Doug Wheelock, who did a similar repair on the International Space Station in 2010. As Wheelock told Universe Today, there are literally hundreds (likely, thousands) of people working the procedures to get this done.
The timeline. NASA really, really wants to wrap this repair up soon, and it’s not because of the holidays. Dec. 27 marks a planned spacewalk for the Russian side of the station that is totally unrelated to what is going on right now. The Americans are hoping they won’t disrupt the schedule so that the Russians can proceed with their experiment swapouts and foot restraint installation as originally planned.
The robotic arm. Hopkins is a much more junior spacewalker than the experienced Mastracchio, who has seven spacewalks underneath his belt before today. Hopkins, who is on his first spaceflight, is in a situation where he can expect more flights in the future. So any training he can get in orbit would be fantastic as he would be a stronger asset on future missions. So, Mastracchio was supposed to ride the Canadarm2 on the second spacewalk, but at that time NASA anticipated it would take three to do the repair. Since the crew finished the work so swiftly, it’s likely only two will be needed. As such, giving Hopkins the slot would be the best practice, NASA and the crew determined.
The future pump move. NASA decided not to move the faulty pump from its temporary stowage location until later. Due to thermal conditions on station, it can stay in its temporary spot until June. This saves the spacewalkers extra work now, but someone will need to head outside by summer to move it to a more permanent location.
Kids’ drawings are the best, as astronaut Karen Nyberg proudly shows in her latest mini-quilt piece. The astronaut — who just spent six months in orbit during Expedition 36/37 — is also a prolific quilter and drew inspiration from her son, three-year-old Jack, in this quilt posted on Pinterest. The drawing shows how quickly Jack changed during her mission, she wrote.
“When I left for space station in May, my son was drawing only lines, circles, and squiggles. When I returned in November, he was drawing people. He told me this picture is ‘Jack playing in the grass on a sunny day.’ ”
We’re guessing Nyberg is having an easier time quilting now that she isn’t working in microgravity anymore. The video below explains the challenges she had doing quilting in orbit and making sure that sharp pins didn’t just float away and cause problems on station.
Nyberg is married to astronaut Doug Hurley (who piloted the final shuttle mission, among other things) and as the Houston Chronicle’s Eric Berger points out in November, the parents have lots of experience helping each other out with child care during training and missions.
