Flame and fireworks. That’s what the Automated Transfer Vehicle Albert Einstein appeared to astronauts to be like as it made a planned dive into Earth’s atmosphere Nov. 2. The European Space Agency ship spent five months in space, boosting the International Space Station’s altitude several times and bringing a record haul of stuff for the astronauts on board the station to use.
According to the European Space Agency, this is the first view of an ATV re-entry that astronauts have seen since Jules Verne, the first, was burned up in 2008. Controllers moved the spacecraft into view of the Expedition 37 crew to analyze the physics of breakup.
Also, yesterday you may have seen an article concerning a picture a photographer snapped of the ATV burning up on Earth. After publishing it, we then realized we were in error with that information. But it turns out the photographer actually DID capture the ATV-4 ina subsequent image. We’ve now updated the article a second time. Senior Editor Nancy Atkinson writes:
Here’s a story that we’ve updated a couple of times, and now it ultimately has a happy ending. We originally posted a picture from Oliver Broadie who thought he captured an image of the ATV-4 Albert Einstein right before it burned up in the atmosphere. That image, see below, was ultimately determined to be of the International Space Station and not the ATV-4, so yesterday we pulled the image and explained why. But now, thanks to a great discussion between the photographer and satellite tracker Marco Langbroek (see it in the comment section), they have determined that Oliver actually did capture the ATV-4 in a subsequent image taken about 4 minutes later. Thanks to both Ollie and Marco for analyzing the timing and images. Also, we were in error for saying that the image showed the ATV-4 burning up in the atmosphere. That was my mistake (Nancy).

And you can now actually see images of ATV-4’s fiery plunge taken by the ISS astronauts here — Nancy Atkinson, Senior Editor.

Each Automated Transfer Vehicle series ferries cargo to the International Space Station, stays attached for a few months to do routine boosts to the station’s altitude, then leaves with a haul of trash to burn up in Earth’s atmosphere.

Albert Einstein carried a record 5,467 pounds (2,480 kg) of cargo for its type of vehicle and also brought away the most garbage of the series of vehicles. It did six reboosts of the ISS’ altitude and among its precious cargo was a GPS antenna for Japan’s Kibo laboratory as well as a water pump for Europe’s Columbus laboratory, according to the European Space Agency.
The cargo ship undocked from the space station on Oct. 28 after five months in space. It burned up Nov. 2 at 12:04 GMT within sight of the astronauts. The next of the series, Georges Lemaitre, is in French Guiana for a launch aboard an Ariane 5 rocket that will take place in June 2014.
The ATVs are just one of many space trucks that visit the International Space Station. Check out this recent article on cargo ships past and present to see other ones that ferry stuff into space.

From guitar playing to quilting, it’s clear that the astronauts aboard the International Space Station have excellence in other interests besides their core jobs. NASA astronaut Karen Nyberg, shortly finishing up her nearly half-year mission in space as part of Expedition 35/36, is an accomplished crafter. She’s found time to make a dinosaur from spare scraps and severalheadbandsto keep her long hairfrom flying in her face. And now she wants you to join with her work.
Despite her skill in crafting, however, Nyberg says working in microgravity is quite the challenge. She keeps all her supplies in a ziploc so they don’t go flying in all directions when she’s not using them. A pile felt board keeps everything secured while she is working on a piece.
But measuring and cutting when you can’t lay something down means working takes a long, long time. That’s what makes this single nine-inch-by-nine-inch quilting block below so precious.

Nyberg says her work is “far from being a masterpiece”, but is inviting other quilters to share the metaphorical stage with her creation. Quilters anywhere in the world can make star pieces of their own and send it to the International Quilting Festival organizers for display in fall 2014. If all goes well, Nyberg expects to make an appearance to view the creation herself.
Here’s a short summary of the requirements (which you can read officially on this page):
– Have a star theme;
– 9.5 inches (24 centimeters) square;
– One block per person, signed on the front with a permanent marker marking name and location;
– Mail by Aug. 1, 2014 to “Star Block Challenge, Attn: Rhianna Griffin, 7660 Woodway Ste. 550, Houston, TX 77063.”
By the way, the full video of Nyberg explaining her sewing challenges makes you sympathize with how hard microgravity can be. Although the backflip she does at the end likely makes up for at least some of it, right?

KENNEDY SPACE CENTER, FL – Orion, the first NASA spaceship that will ever carry Earthlings to deep space destinations, has at last been “powered on” for the first time at the manufacturing facility at the Kennedy Space Center (KSC) where it’s the centerpiece of a beehive humming 24/7 with hi tech processing activities in all directions.
“Power On” marks a major milestone ahead of the maiden space bound Orion test flight dubbed “EFT-1” – now at T-Minus 1 year and counting!
NASA and prime contractor Lockheed Martin recently granted Universe Today an exclusive in depth inspection tour of the impressive Orion EFT-1 crew module, service module and associated hardware destined for the crucial unmanned test flight slated for liftoff from Cape Canaveral in September 2014.
“We are moving fast!” said Jules Schneider, Orion Project manager for Lockheed Martin at KSC, during an exclusive interview with Universe Today as we spoke beside the Orion EFT-1 spacecraft inside the clean room.
“We are bringing Orion to life. Lots of flight hardware has now been installed.”

“We are working 24 hours a day, 7 days a week,” Schneider told me.
Some 200 people are actively employed on building Orion by Lockheed Martin at the Kennedy Space Center.
“There are many significant Orion assembly events ongoing this year,” said Larry Price, Orion deputy program manager at Lockheed Martin, in an interview with Universe Today at Lockheed Space Systems in Denver.
“This includes the heat shield construction and attachment, power on, installing the plumbing for the environmental and reaction control system, completely outfitting the crew module, attached the tiles, building the service module and finally mating the crew and service modules (CM & SM),” Price told me.
I have been very fortunate to periodically visit Orion up close over the past year and half to evaluate the testing and assembly progress inside the Operations and Checkout Building at KSC where the vehicle is now rapidly coming together, since the bare bones pressure vessel arrived to great fanfare in June 2012.
For the first time Orion looked to my eyes like a real spaceship, rather than the backbone shell outfitted with hundreds of important test harnesses, strain gauges and wiring to evaluate its physical and structural integrity.

Engineers and technicians at KSC have removed the initial pressure testing gear and are now installing all the flight systems and equipment – such as avionics, instrumentation, flight computers, thrusters, wiring, plumbing, heat shield and much more – required to transform the initial empty shell into a fully functioning spacecraft.
“The Orion skeleton was here before. Now we are putting in all of the other systems,” Schneider explained to me.
“We are really busy.”
“So far over 66,000 Orion parts have been shipped to KSC from over 40 US states,” Price explained.
The heat shield was due to arrive soon and technicians were drilling its attachment ring holes as I observed the work in progress.
“The propulsion, environmental control and life support systems are now about 90% in. The ammonia and propylene glycol loops for the thermal control system are in. Many of the flight harnesses are installed.”
“All of the reaction control thrusters are in – fueled by hydrazine – as well as the two hydrazine tanks and a helium tank. Altogether there are 12 hydrazine pods with two thrusters each,” Schneider elaborated.
The power distribution unit (PDU) – which basically functions as Orion’s computer brains – was installed just prior to my visit. All four PDU’s – which issue commands to the vehicle – were built by Honeywell.
Technicians were actively installing fiber optic and coaxial cables as I watched. They also were conducting leak tests on the environmental control coolant (ECLS) systems which had to be completed before the ‘power on’ testing could begin – in order to cool the avionics systems.
Thermal protection system (TPS) tiles were being bonded to the back panels which ring Orion. The TPS panels get attached early in 2014.
“This is real stuff,” said Schneider gleefully.

NASA says that “the preliminary data indicate Orion’s vehicle management computer, as well as its innovative power and data distribution system — which use state-of-the-art networking capabilities — performed as expected” during the initial crew module power on.
About two months or so of power on functional testing of various systems will follow.
Just like the configuration used in the Apollo era, the Orion crew module will sit atop a service module – and that work is likewise moving along at a rapid clip.
“The Orion service module (SM) is also almost complete,” Schneider said as he showed me the service module structure.
“Structurally the SM is 90% done. The active thermal control system is in and all the fluid systems are welded in and pressure tested.”

Orion EFT-1 will blastoff atop a mammoth United Launch Alliance Delta IV Heavy rocket – the most powerful booster in America’s arsenal since the shuttle’s retirement in 2011.
The crew module and service module (CM/SM) will be mated inside the O&C and then be placed onto a mission adapter that eventually attaches to the top of the Delta IV Heavy booster.
They will be mated at the exact same spot in the O&C Building where the Apollo era command and service modules were stacked four decades ago.
Currently, the schedule calls for the Orion CM/SM stack to roll out to Kennedy’s Payload Hazardous Services Facility (PHSF) for servicing and fueling late this year, said Larry Price.
After that the CM/SM stack is transported to the nearby Launch Abort System Facility (LASF) for mating to the emergency Launch Abort System (LAS).
All that work could be done around March 2014 so that ground operations preparing for launch can commence, according to Price.
“In March 2014 we’ll be ready for ground ops. The normal launch processing flow starts in June 2014 leading to Orion’s launch from pad 37 in September 2014.”
“It’s very exciting and a tribute to the NASA and contractor teams,” Price said.
The 2014 uncrewed flight will be loaded with a wide variety of instruments to evaluate how the spacecraft behaves during launch, in space and then through the searing heat of reentry.
The two-orbit, four- hour flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years.

Although the mission will only last a few hours it will be high enough to send the vehicle plunging back into the atmosphere and a Pacific Ocean splashdown to test the craft and its heat shield at deep-space reentry speeds of 20,000 mph and endure temperatures of 4,000 degrees Fahrenheit – like those of the Apollo moon landing missions.

The EFT-1 mission will provide engineers with critical data about Orion’s heat shield, flight systems and capabilities to validate designs of the spacecraft, inform design decisions, validate existing computer models and guide new approaches to space systems development. All these measurements will aid in reducing the risks and costs of subsequent Orion flights before it begins carrying humans to new destinations in the solar system.
“The Orion hardware and the Delta IV Heavy booster for the EFT-1 launch are on target for launch in 2014,” Scott Wilson, NASA’s Orion Manager of Production Operations, told Universe Today in an interview.

Here’s a cool example of a satellite recycling project. NASA used to have a probe called QuikSCAT that took a look at ocean wind speeds — including hurricanes, storms and typhoons. After 10 years of loyal service, the satellite failed in 2009 and a full replacement looked expensive. Now, however, spare parts for QuikSCAT are going to be used on the International Space Station for a low-budget fix (which the agency says will work just fine).
The parts are old — they are from the 1990s — but incredibly, they are functional. NASA also added some newer, commercially available hardware to make ISS-RapidScat fit in the space station as well as the SpaceX Dragon spacecraft that will bring it to orbit in early 2014.
Because this is very much a low-cost project, certain design compromises were made — like not using radiation-hardened computer chips, which is normal in scatterometers of this sort. (This type of device harmlessly sends low-energy microwaves off the Earth’s service to get the information it needs.)

“If there’s an error or something because of radiation, all we have to do is reset the computer. It’s what we call a managed risk,” stated Howard Eisen, the ISS-RapidScat project manager at NASA’s Jet Propulsion Laboratory.
There’s another big difference with this scatterometer mission: it’s flying in a different orbit that most. A typical mission will do a sun-synchronous orbit, making it cross the Earth’s equator at the same local time every time it orbits the planet (say, 12 p.m. local.) The ISS, however, passes over different parts of Earth at different times.
“This means the instrument will see different parts of the planet at different times of day, making measurements in the same spot within less than an hour before or after another instrument makes its own observations,” NASA stated.

“These all-hour measurements will allow ISS-RapidScat to pick up the effects of the sun on ocean winds as the day progresses. In addition, the space station’s coverage over the tropics means that ISS-RapidScat will offer extra tracking of storms that may develop into hurricanes or other tropical cyclones.”
NASA plans to share information with the European MetOp ASCAT scatterometer. Between the two missions, NASA expects that about 90% of Earth’s surface will be examined at least once a day,with some parts visible several times a day.
All in all, NASA is presenting the recycling project as a boon at a time when the agency is grappling with its 2014 budget request. Instead of an estimated cost of $400 million to launch a replacement QuikSCAT, the cost of ISS-Rapidscat is expected to reach $26 million.

The privately built Dream Chaser ‘space taxi’ that was damaged after landing during its otherwise successful first ever free-flight glide test on Saturday, Oct 26, is repairable and the program will live on to see another day, says the developer Sierra Nevada Corp., (SNC).
The Dream Chaser engineering test vehicle skidded off the runway and landed sideways when its left landing gear failed to deploy at the last second during touchdown on runway 22L at Edwards Air Force Base, Calif., said Mark Sirangelo, corporate vice president for SNC Space Systems, at a media teleconference.
The primary goal of the Oct. 26 drop test was to see whether the Dream Chaser mini-shuttle would successfully fly free after being released by an Erickson Air-Crane from an altitude of over 12,000 feet and glide autonomously for about a minute to a touchdown on the Mojave desert landing strip.
“We had a very successful day with an unfortunate anomaly at the end of the day on one of the landing gears,” said Sirangelo.
Dream Chaser is one of three private sector manned spaceships being developed with funding from NASA’s commercial crew program known as Commercial Crew Integrated Capability (CCiCap) initiative to develop a next-generation crew transportation vehicle to ferry astronauts to and from the International Space Station – totally lost following the space shuttle retirement.

The unmanned approach and landing test (ALT) accomplished 99% of its objectives and was only marred by the mechanical failure of the left tire to drop down and deploy for a safe and smooth rollout.
SNC released a short 1 minute video of the test flight – see below – showing the helicopter drop, dive, glide and flare to touchdown. The failure of the landing gear to drop is clearly seen. But the video cuts away just prior to touchdown and does not show the aftermath of the skid or damage to the vehicle.
“The Dream Chaser spacecraft automated flight control system gently steered the vehicle to its intended glide slope. The vehicle adhered to the design flight trajectory throughout the flight profile. Less than a minute later, Dream Chaser smoothly flared and touched down on Edwards Air Force Base’s Runway 22L right on centerline,” said SNC in a statement with the video.
The vehicle is “repairable and flyable again,” Sirangelo noted.
More good news is that the ships interior was not damaged and the exterior can be fixed.
Dream Chaser measures about 29 feet long with a 23 foot wide wing span and is about one third the size of NASA’s space shuttle orbiters.

Since there was no pilot in the cockpit no one was injured. That also meant that no evasive action could be taken to drop the gear.
“We don’t think it’s actually going to set us back,” Sirangelo noted. “In some interesting way, it might actually accelerate it.
NASA’s commercial crew initiative aims at restoring America’s manned spaceflight access to low Earth orbit and the International Space Station (ISS) – perhaps by 2017 – following the forced shutdown of the Space Shuttle program in 2011.
Until an American commercial space taxi is ready for liftoff, NASA is completely dependent on the Russian Soyuz capsule for astronaut rides to the ISS at a cost of roughly $70 million per seat.
Because Congress continues to significantly cut NASA’s budget further delays can be expected – inevitably meaning more payments to Russia and no savings for the American tax payer.
SNC was awarded $227.5 million in the current round of NASA funding and must successfully complete specified milestones, including up to five ALT drop tests to check the aerodynamic handling in order to receive payment.

This particular vehicle had been intended to fly two test flights. Further drop tests were planned with a new test vehicle to be constructed.
The way forward is being evaluated.
“We don’t think there is going to be any significant delay to the program as a result of this. This was meant to be a test vehicle with a limited number of flights,” Sirangelo said.
SNC and NASA have assembled a team to investigate the cause of the anomaly.
“SNC cannot release any further video at this time,” said SNC.

The Expedition 37 crew onboard the International Space Station closed the hatch and said goodbye to the ATV-4 “Albert Einstein” cargo ship early this morning, Oct. 28. Europe’s 4th Automated Transfer Vehicle undocked at 08:55 UTC (4:55 a.m. EDT). The cargo carrier was filled with trash and it will be deorbited on Nov. 2 for a destructive entry back into the Earth’s atmosphere over the Pacific Ocean. ATV-4 has been at the ISS since June 15, delivering more than 7 tons of food, fuel and supplies. Its departure helps prepare for more action at the ISS: the current Soyuz spacecraft docked at the station will be moved to a different location so that a new Soyuz can dock with three new crew members. The Soyuz TMA-11M is scheduled to launch on Nov. 6, 2013 with the Expedition 38/39 crew of Rick Mastracchio, Koichi Wakata, Mikhail Tyurin.

The engineering test article of the commercial Dream Chaser spaceship being developed by Sierra Nevada Corp (SNC) suffered some significant damage during its critical 1st ever approach-and-landing (ALT) drop test on Saturday, Oct. 26, in California due to an unspecified type of malfunction with the deployment of the left landing gear.
The Dream Chaser mini-shuttle suffered “an anomaly as it touched down on the Runway 22L at Edwards Air Force Base, Calif.,” according to a post-test statement from NASA.
A report at NASA Spaceflight.com indicated that the Dream Chaser “flipped over on the runway” after touchdown.
The full extent of damage to the winged vehicle or whether it can be repaired and reflown is not known at this time. No photos or details explaining the damage have yet emerged – beyond brief press releases issued by SNC and NASA.
The performance of the vehicles’ nose skid, brakes, tires and other flight systems is being tested to prove that it can safely land an astronaut crew returning from the space station after surviving the searing heat of re-entry from Earth orbit.
This initial atmospheric drop test was conducted in an automated mode. There was no pilot on board and no one was hurt on the ground.
“No personnel were injured. Damage to property is being assessed,” said NASA. “Edwards Air Force Base emergency personnel responded to scene as a precaution.
“Support personnel are preparing the vehicle for transport to a hangar.”

To date this test vehicle has successfully accomplished a series of runway tow and airborne captive carry tests.

During Saturday’s test, SNC was performing the first in a series of free-flight approach-and-landing tests with the Dream Chaser prototype test vehicle known as the ETA.
The prototype spaceship was released as planned from its carrier aircraft, an Erickson Air-Crane helicopter, at approximately 11:10 a.m. Pacific Standard Time (2:10 p.m. EDT), said SNC in a statement.
Dream Chaser awaits launch atop United Launch Alliance Atlas V rocketThe post release flare and touchdown appeared normal at first until the left landing gear deployment failed at some point after runway touchdown.
“Following release, the Dream Chaser spacecraft automated flight control system gently steered the vehicle to its intended glide slope. The vehicle adhered to the design flight trajectory throughout the flight profile. Less than a minute later, Dream Chaser smoothly flared and touched down on Edwards Air Force Base’s Runway 22L right on centerline,” according to the SNC press release.
SNC went on to say that reviews are in progress to determine the cause of the landing gear failure.
“While there was an anomaly with the left landing gear deployment, the high-quality flight and telemetry data throughout all phases of the approach-and-landing test will allow SNC teams to continue to refine their spacecraft design. SNC and NASA Dryden are currently reviewing the data. As with any space flight test program, there will be anomalies that we can learn from, allowing us to improve our vehicle and accelerate our rate of progress.”
The engineering test article (ETA) is a full sized vehicle.
Dream Chaser is a reusable mini shuttle that launches from the Florida Space Coast atop a United Launch Alliance Atlas V rocket and lands on the shuttle landing facility (SLF) runway at the Kennedy Space Center, like the space shuttle.
“It’s not outfitted for orbital flight. It is outfitted for atmospheric flight tests,” said Marc Sirangelo, Sierra Nevada Corp. vice president and SNC Space Systems chairman told Universe Today previously.
“The best analogy is it’s very similar to what NASA did in the shuttle program with the Enterprise, creating a vehicle that would allow it to do significant flights whose design then would filter into the final vehicle for orbital flight,” Sirangelo told me.
We’ll provide further details as they become known.

Here’s the latest attempt to hunt down the water leak that aborted Luca Parmitano’s spacewalk in July: two astronauts aboard the International Space Station removed and replaced a fan pump and water separator inside the spacesuit earlier this week.
All spacewalks with NASA suits are on hold while the agency investigates the leak, and they have been trying mightily. In late July, then on-station NASA astronaut Chris Cassidy demonstrated how the pool of water spread within the helmet (as you can see in these YouTube videos).
This week, on-orbit NASA astronauts Mike Hopkins and Karen Nyberg delved further. While the astronauts are trained before their missions on some suit repairs, this particular type was not something that was covered before they left Earth. After Mission Control walked them through what to do, the astronauts proceeded cautiously as they did the work, NASA said.
“Our engineering teams have identified several different components of the suit, designing a big fault tree, and this is just one of the components that we think could have contributed to the leak in the suit,” said Alex Kanelakos, an extra-vehicular activity flight controller and astronaut instructor, in a new YouTube video.
“Specifically, the water separator is what we’re concentrating our efforts on today.”
As Kanelakos explained, a motor inside the suit drives the fan pump and water separator. The fan circulates oxygen, and the pump pumps the coolant fluid. The water separator, meanwhile, takes out moisture (water) from the ventilation loop and gas that could be trapped inside the water coolant loop. The dried-out air is then returned to the crew member for breathing, and the cycle continues.

In September, Cassidy told Universe Today that the spacesuit is expected to come back to Earth during a future SpaceX Dragon cargo flight. That type of spacecraft is (unusually among space trucks) designed to survive re-entry in the atmosphere, allowing engineers on the ground to examine the spacesuit after it comes back.
Cassidy added that the situation was serious, and he supported NASA’s decision to end the spacewalk (which he was also participating in.) He didn’t think, however, that Parmitano was in immediate danger of drowning. For his part, Parmitano wrote a blog post on the European Space Agency website after his spacewalk, saying that space is an “inhospitable” arena.

As any astronaut is trained to do, Parmitano did consider other contingencies while the leak was happening, he wrote:
“The only idea I can think of is to open the safety valve by my left ear: if I create controlled depressurisation, I should manage to let out some of the water, at least until it freezes through sublimation, which would stop the flow. But making a ‘hole’ in my spacesuit really would be a last resort,” he wrote.
That fix, however, was not implemented as Parmitano and Cassidy made their way back to the station in time for their crewmates to repressurize the hatch and bring their Italian crewmate safely inside.
