Can The International Space Station Fit Bigger Astronaut Crews?

Things are a little more crowded than usual in the International Space Station. For a few days, nine astronauts and cosmonauts are floating in the cramped quarters of the orbiting complex. Typical crew sizes range between three and six. How did the astronauts find room to work and sleep?

“One of the things we had to do was make space for them,” said European Space Agency astronaut Luca Parmitano in a rare press conference today (Nov. 8) from orbit, which included participation from Universe Today. He then explained a procedure where the astronauts swapped a Soyuz crew spacecraft from one Russian docking port to another a few days before Expedition 38/39’s crew arrived on board on Thursday. This cleared the way for three more people to arrive.

“We [also] had to adjust for emergency procedures. All of our procedures are trained and worked for a group of six. We had to work on a way to respond if something happened.” As for sleeping, it was decided the six people already on board, “as seniority, would stay in the crew quarters.” The newer astronauts have temporary sleeping arrangements in other modules until the ranks thin out a bit on Sunday.

So this works for a short while, but what about the long-term? Could the station handle having nine people there for weeks at a time, rather than six, and would there be enough science work to go around?

“I think, absolutely, moving to nine people is doable and in terms of the science would be fantastic,” NASA astronaut Karen Nyberg said. The station partners had experience with increasing crews before, she added, as for several years a regular space station rotation was only three astronauts during construction. Bumping up to the current maximum of six was a “big jump.”

“One of the things to be concerned about our environmental control system, our CO2 [carbon dioxide scrubbing] system … and also the consumables and the supplies we need,” she added. “Making up the science for us to do would be very doable. I think the hard part would be getting the systems to accommodate nine people.”

Parmitano, Nyberg and Russian cosmonaut Fyodor Yurchikhin plan to return to Earth Sunday, but a busy weekend lies ahead. On Saturday, Roscosmos (Russian Federal Space Agency) flight engineers Oleg Kotov and Sergey Ryazanskiy of the Russian Federal Space Agency will start a spacewalk around 9:30 a.m. EST (2:30 p.m. UTC) if all goes to plan.

As part of the Olympic torch relay ahead of the Sochi games in 2014, they will briefly bring the Olympic torch outside with them, unlit, before doing some outside maintenance.

“After the photo opportunity, Kotov and Ryazanskiy will prepare a pointing platform on the hull of the station’s Zvezda service module for the installation of a high resolution camera system in December, relocate … a foot restraint for use on future spacewalks and deactivate an experiment package,” NASA stated in a Thursday press release.

Several journalists were unable to ask questions during the NASA portion of the press conference, which included participation from countries covered by NASA, the European Space Agency, the Japanese Aerospace Exploration Agency and Roscosmos (the Russian Federal Space Agency).

“We had a failure in a crucial component in the phone bridge,” NASA spokesman Kelly Humphries told Universe Today following the media event. They don’t know what component failed, but most of the journalists were unable to hear the moderator or the astronauts.

“A piece of equipment picked the wrong time to fail,” Humphries said

NASA will do a thorough investigation before holding another event like this to make sure it works for everyone.

Here’s a replay of the news conference:

Chris Hadfield On Space-y $5 Bill: ‘It Reminds Us That Our Dreams Do Not Have A Limit’

In Canada, “gimme five” could soon have a space connotation. Today the country announced it is preparing to put new polymer $5 bills into circulation that feature Canadian robotics and an astronaut.

At the official circulation ceremony near Montreal, Que. was none other than Canadian astronaut Chris Hadfield, who brought unprecedented social media attention to space through social media. The world was enchanted by his guitar playing and crying in space, but in space circles he also commands a lot of respect. The trilingual Hadfield visited two space stations, helped build the robotic Canadarm2 in space, and commanded the International Space Station, among other achievements.

His presence was appropriate, because the $5 bill has a lot of robotics on it. Canadarm2, Dextre and an astronaut are splashed across one face of the bill. “It reminds us that our dreams do not have a limit,” Hadfield said in French.

“It serves as a reminder to all Canadians of the dedication and hard work of so many people across the Canadian Space Agency and the space industry across Canada, and the scientists and engineers that make the design of these incredibly complex robots and getting them into space somehow easy,” Hadfield added in English. “Being involved in it is the real inspiration part. Who knows where such innovation can take us.”

The Bank of Canada first unveiled the new $5 and $10 bills in April, while Hadfield was at the helm of the station. Canada’s central banking authority is touting the new plasticized bill series as more durable than past cotton-based ones, with better counterfeit measures such as transparency. Polymer bills are available already in $20, $50 and $100 denominations.

Opposite to the space-themed side of the $5 bill is a picture of past prime minister Wilfrid Laurier. The new $10 bill features a train on one side and (as with the past iteration) John A. Macdonald, the first Canadian prime minister, on the other.

Hadfield himself has featured on both Canadian currency and stamps in the past: the Royal Mint of Canada issued two coins with him and Canadarm2 in 2006, and Hadfield was among several astronauts put on to Canadian stamps in 2003.

‘Stairways to Mars’ Concept Proposes Truck Stops Near The Red Planet

Any road trip requires rest stops to refuel and rest. That’s especially true of planetary exploration, as it would take months between destinations. In that spirit, here is a new concept for “Mars truck stops” from the Space Development Steering Committee, which they call “Stairways to Mars.”

For those who aren’t aware, the committee is a coalition of space advocates. Included in the group are the heads of the National Space Society, the Space Frontier Foundation, and the Mars Society, SDSC said, as well as a list of past astronauts, high-ranking NASA employees and others. (The founder is Howard Bloom, who was a former visiting scholar at New York University’s graduate psychology department, among other positions.)

They provide commentary on NASA funding (such as this March article on sequestration). Also in March, the group advertised a White House petition to provide space-based solar power.

So how would a Mars truck stop work? In a nutshell, this is what SDSC proposes:

– Beams are constructed in space “just like a giant erector set”, according to a statement from John Strickland, SDSC chief analyst. This would be accomplished using “robots on rails” that could build the first part, then “extend … its own rails along the beam as it goes.”

–  Solar panels are added on to the beam to provide power;

– Components are then added according to need. Pictures from SDSC show items such as fuel tanks on the truck stop. If ambitions soared even higher, the concept could even be built upon to make a larger space colony modelled on “O’Neill colonies”, as shown below.

It should be emphasized that this is a concept, with no funding or firm plans yet, but for what it’s worth the committee says it could move quickly. “These plans are budgeted to cost LESS than the current NASA program for our next step in space — the $40 billion Space Launch System and Orion Capsule. What’s more, the first steps of the Stairway to Mars are achievable in three years,” the committee writes.

One possible location for this kind of truck stop would be at the Earth-Moon L1 Lagrange point, or a spot in space where gravities from different bodies approximately equal each other out and allow an object to hover in place. Lagrange points are already used for several space missions, including the Planck telescope that was just decommissioned.

What do you think of the concept? Let us know in the comments.

Here’s What A Spacecraft Looks Like Burning Up (Plus Correction of Past Article)

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).

More orbital pictures of the ATV burning up are available in this ESA Flickr set.

UPDATE: Editor’s note: 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.

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.

SpaceX Signs Pact To Start Rocket Testing At NASA Stennis

SpaceX — the maker and operator of the Dragon spacecraft that runs periodic cargo flights to the International Space Station — has signed a contract to research, develop and test Raptor methane rocket engines at the NASA Stennis Space Center in southern Mississippi.

The California-based company plans to use the E-2 test stand at Stennis, which is able to support both vertical and horizontal rocket engine tests. (Here are some more technical details from NASA on its capabilities.)

“We have been talking with SpaceX for many years about working at Stennis Space Center, and I am pleased to officially welcome them to our Mississippi family. I hope this is just the beginning of their endeavors in our state,” stated U.S. Senator Thad Cochran (R-Miss) in response to the news. A press release from his office said the presence of the private space company would boost jobs in the region.

There’s little information on SpaceX’s website about what the Raptor engine is or specific development plans, but Space News reports that it would be used for deep-space missions. SpaceX CEO Elon Musk has mentioned the engine previously when talking about Mars missions, according to multiple media reports.

“We are looking to test the whole engine at Stennis, but the first phase starts with the components,” SpaceX spokesperson Emily Shanklin said in the Space News report. “The E-2 stand at Stennis is big enough for components, but we would need a bigger stand for the whole Raptor.”

The two sides are reportedly hashing out a Space Act agreement to establish user fees and other parameters. Once that’s finished, the testing will begin, perhaps as early as next year. SpaceX currently does most of its rocket testing in Texas.

Other parties in the agreement — which was signed by Governor Phil Bryant — include the Mississippi Development Authority, the Harbor Commission and Hancock County Port.

Moonstruck: Private Moon Robot Competition Coming To A Theater Near You

To drum up publicity for the Google Lunar XPRIZE missions, the organization has produced a “dome film” about exploring the moon through the past to the future — and is giving away the product for free to dozens of dome theaters and planetariums worldwide.

Among Back To the Moon For Good’s first appearances will be the National Science Center at Leicester, United Kingdom on Nov. 6, and a United States premiere is on its way shortly. A full list of participating venues so far is at this website. The target audience for the show (which is designed for a wraparound theater) is elementary and secondary school students.

“It was Mercury, Gemini and Apollo that took the us into space, and ultimately to the moon, and this was incredibly exciting and was responsible for lots of folks going into science and technology over the years,” said Bob Weiss, who is XPRIZE’s president and executive producer of the film, in a Universe Today interview.

“We would like to provide a 21st century version of that, but as a new kind of space mission, more interactive and participatory,” he added, saying that social media and Internet websites would be a couple of ways people at home can stay engaged in the mission or missions to the moon. (That definitely wasn’t possible generally when Apollo 11, the first moon mission, landed in 1969!)

The narrator of the show is Tim Allen, an actor best known for the Home Improvement series of the 1990s. Allen, by the way, is a fan of space himself (says Weiss) and also appeared in a 1999 parody science fiction film called Galaxy Quest. Weiss said the desire was to find somebody who was family-friendly, well-known and enthusiastic about the project.

By the way, loyal fans of Home Improvement will recall that astronauts appeared on the “Tool Time” segment of the show on several occasions, usually after Hubble Space Telescope repair missions. (NASA astronaut Ken Bowersox appeared three times himself, in 1994, 1996 and 1998.)

In Season 3 show “Reality Bytes” in 1994, Tim Allen’s character asked STS-61 commander Dick Covey what the difference was between repairs in space and repairs on Earth. “It’s actually a lot like using tools here on Earth. Except there’s no gravity, so you don’t have to worry about dropping a tool on your foot,” Covey quipped.

If “Tool Time” was taking place now, we wonder if Allen would also be interviewing private companies working on robotic and human spaceflight. XPRIZE is still chugging along well, Weiss said, and added some of the teams have signed launch contracts to send their robots to the moon. (He declined to provide many details, citing confidentiality reasons.)

“We have folks who have launch contracts to go to the moon, and another serious sign is when there is real flight hardware that is being built and tested. I have seen myself some of this hardware, and there are teams that are really racing to beat each other,” he said.

“There are approximately 20 teams around the world competing to do this. It has been an interesting competition, watching some teams drop off and some devolve and recombine with each other.”

Teams have until Dec. 31, 2015 to send a robotic spacecraft to the moon, travel 500 meters (whether on, below or above the surface), and transmit two “mooncasts” for Earth. At least $40 million in “incentive-based prizes” are up for grabs. We’ve covered a few of the concepts on Universe Today before, such as one team seeking to send robots into moon caves, and a college group trying to put a rover on the surface.

Check out more information on the teams on the Google Lunar XPRIZE website.

Dream Chaser spaceship test article damaged during 1st Free-Flight Drop Test

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.”

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.

The NASA seed money 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 one of the American commercial space taxis 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.

SNC was awarded $227.5 million in the current round of NASA funding and must complete specified milestones including up to five ALT drop tests to check the aerodynamic handling.

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

Development of crew versions of the SpaceX Dragon and Boeing CST-100 capsules are also being funded by NASA’s commercial crew program office.

Dream Chaser can carry a crew of up to seven and is the only reusable, lifting body shuttle type vehicle with runway landing capability among the three competitors.

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.

The 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.

Japanese ‘Space Cannon’ On Track For Aiming At An Asteroid: Reports

Watch out, asteroid 1999 JU3: you’re being targeted. As several media reports reminded us, the Japan Aerospace Exploration Agency (JAXA)’s Hayabusa-2 asteroid exploration mission will carry a ‘space cannon’ on board — media-speak for the “collision device” that will create an artificial crater on the asteroid’s surface.

“An artificial crater that can be created by the device is expected to be a small one with a few meters in diameter, but still, by acquiring samples from the surface that is exposed by a collision, we can get fresh samples that are less weathered by the space environment or heat,” JAXA states on its website.

Reports indicate JAXA is on schedule to, er, shoot this thing into space for a 2018 rendezvous with an asteroid. The spacecraft will stick around the asteroid for about a year before heading back to Earth in 2020. The overall aim is to learn more about the origin of the solar system by looking at a C-type asteroid, considered to be a “primordial body” that gives us clues as to the early solar system’s makeup.

Check out more on Hayabusa-2 on JAXA’s website.

Incredible Vertical-Landing Grasshopper Rocket Has Retired

Did you take a moment to look at that August video of the Grasshopper rocket deliberately going sideways and then appearing to hover for a bit before returning to Earth? For more video fodder, there’s also this high-flying test the rocket took in October.

We hope you enjoyed these views, because Grasshopper is being retired. SpaceX now wants to focus its energy and resources on to the larger Falcon 9-R first stage, which should see its first test flight in New Mexico this December.

It sounds like SpaceX would have loved to go further, in a sense. “In some ways we’ve kind of failed on the Grasshopper program because we haven’t pushed it to its limit,” SpaceX president Gwynne Shotwell said at the International Symposium for Personal and Commercial Spaceflight (ISPCS) in New Mexico last week, as reported in the NewSpace Journal. “We haven’t broken it.”

Grasshopper took eight test flights during its flight history, which spanned about a year between September 2012 and October 2013. It was intended to test Vertical Takeoff Vertical Landing technology (VTVL). The strange appearance of a rocket leaving Earth and gently, deliberately touching back down again turned heads — even in the general public.

We have coverage — and videos! — of most of its past test flights here (the dates below are flight dates, not publication dates)

Most rockets are single-use only and are discarded either in orbit or (better yet, for space debris concerns) are put in a path to burn up in Earth’s atmosphere. SpaceX, however, wants its next-generation Falcon 9 rocket to have a reusable first stage to cut down on launch costs. (Grasshopper was about 10 storeys high, while the Falcon 9 will be about 14 storeys tall when carrying a Dragon spacecraft on board.)

As for the Falcon 9 series, a rocket flight in September delivered its payload (which included the Canadian Cassiope satellite) to space successfully, but faced some technical problems with the upper stage — and the first stage, as the rocket was supposed to be slowed down for splashdown.

As Space News reported, two burns were planned. The first worked, but the second burn took place while the rocket was spinning, which affected the flow of fuel. A picture shown by SpaceX demonstrated the rocket was intact three meters above the ocean, although it did not survive after it hit.

“Between the flights we’ve been doing with Grasshopper and this demonstration that we brought that stage back, we’re really close to full and rapid reuse of stages,” Shotwell said in the report.
