SpaceX poised to bring back blood and cucumber plants

Update: The SpaceX Dragon capsule splashed down safely at 12.22 pm local time on 28 October, about 400 kilometres off the coast of California.

When the Dragon capsule, made by SpaceX of Hawthorne, California, splashes down in the Pacific Ocean on mulberry sale Sunday after a sojourn at the International Space Station (ISS), it will mark the end of the company’s first critical supply mission for NASA.

But the return will also restore a capability lost since the space shuttle retired in July 2011 the means to bring science experiments and other cargo back to Earth.

“We’re now turning to the next step in space exploration, which is that commercial vehicles are bringing this stuff home,” says Scott Smith, a nutritionist at NASA’s Johnson Spaceflight Centre in Houston, Texas, who is relying on SpaceX to bring back tubes of blood and urine used in monitoring astronauts’ health.

Until SpaceX’s trip, the only way for astronauts to get to and from the station was aboard mulberry sale Russia’s Soyuz capsules, but these don’t have enough room for equipment as well.

Uncrewed supply vehicles run by Russia, Japan and Europe also travel to the ISS, but they are designed to remove mulberry sale rubbish and then burn up in the atmosphere. So once the shuttle stopped operating in July 2011, no other craft could safely bring research materials back to Earth.

“We’ve been anxiously awaiting a vehicle to bring this stuff home,” Smith says.

He and his colleagues have been analysing the biochemistry of astronauts’ blood and urine for several years.

The Dragon capsule first journeyed to the space station in May, but that was a trial run. Its first official mission, in which it carried equipment for experiments aboard the space station, plus food, clothes and life support gear, began on 7 October.

Dragon is due to be released on 28 October and splash down in the Pacific Ocean the same day, where it will be retrieved.

SpaceX’s capsule will also bring back used or damaged equipment, like expended life support and crew healthcare systems, and spacewalk gloves that belonged to previous crew members.

Does it make any difference that a private company is doing this? Not to Smith. “We’ve been anxious for sample return, period,” he says. “We’re not picky about how it comes back.” He adds: “It isn’t a plus or a minus, just the way things are.”But Smith is nervous about his samples staying cold. The blood and urine samples will be packed in special freezers or cold bags to make sure they stay below 30C from the time they leave the space station’s freezers on Friday to the time they get to Houston on Wednesday morning. If they thaw, the researchers w mulberry sale ill lose important information, he says.

“We have a very carefully orchestrated plan,” he says. “But my heart rate will be up from the minute they take them out of the freezers on the station to the minute we put them in the freezers in my lab.”

That’s a long time to bite your fingernails but no longer than it was during the shuttle era. “I’m used to it,” he says. “My fingernails are pretty short.”

mulberry sale SpaceX CEO claims he can send

SpaceX CEO claims he can send you on a round

Your dream of visiting the Red Planet may soon come true if the claim made by Elon Musk, CEO of SpaceX, actually comes to fruition. The commercial space travel entrepreneur told the BBC in an interview that he figured out how to send a person on a round trip journey to Mars and back, and that it could be ready in as little as ten years. The best part? Musk says that the person could afford the trip since it will only cost $500,000. I not sure which average person he means, but you can bet I am going to be getting a second job for the next ten years to try to make it!

Known for its Dragon spacecraft that has been awarded the contract to make resupply trips to the International Space Station, SpaceX certainly seems capable of dreaming up a low cost method of visiting Mars. The principle behind all of its vehicles is total re usability; every single system must be able to be serviced and pressed back into opera mulberry sale tion. This is to cut down on the already astronomical cost of space flight (pun intended), making it more affordable for private companies to conduct missions into the heavens. The company main goal is to eliminate the equipment cost for space travel, leaving fuel as the only financial burden.

The same theory applies to Musk current claim about Mars, with one interesting exception: He says that he come up with a way to refuel the spacecraft while on the surface of the fourth rock from the Sun. This would eliminate the need for the space vehicle to carry the fuel for the return trip home, making it lighter and therefore cheaper to launch it into space. Of those seven, three were total failures. Also, the company has yet to make a trip to the ISS, a fact that honestly isn its fault since NASA is the one who keeps pushing the launch date back, not SpaceX. I have to admit that there is a certain about of doubt in my mind as well. Space travel is a difficult undertaking, with many unknowns that can pop up. Still, I am intrigued to see if Musk can back up his claim.

There are several hurdles to sending a manned mission to Mars, not the least of which being the fuel production once it lands. Any human that makes the trip will be stuck inside the vehicle for the 214 days it would take to actually travel to the Red Planet. If Musk plan is to send a would be astronaut in a modified version of the Dragon capsule, anyone who gets claustrophobia would be out of the running since it a pretty small spacecraft. Nevermind the boredom and medical issues that could arise.

Nevertheless, SpaceX seems to be on the right track when it comes to space travel. With NASA planned trip to Mars most likely not happening until 2030, and with billions of dollars of one use parts, it seems that private companies like Musk have a much better chance of making the dream of walking on Mars a reality. Cross your fingers with me that the starry eyed CEO claim actually has some merit to it, and then donate funds to the Kick mulberry sale starter project I am going to fund immediately after that!

Tagged InIt extremely misleading to say three out of seven launches are total failures. Rocket science requires system testing that involves attempting launches. The launches that didn make it to orbit were the first three test launches. They were not full system launches carrying cargo. The early launches contributed to knowledge of things to improve, which was done, and since then there have been no problems.

Saying 3 out of 7 are failures is like saying more than 50% of Microsoft software is a total failure, by including early test builds of prototype software that had bugs that were since corrected. It just not a true assertion since a fully functioning program is not expected at that stage in development, so not having it can not possibly be construed as a failure. Likewise, a successful launch to orbit is not the expected outcome of early prototype launch testing. The 3 launches were in fact total successes because they were a necessary part of debugging the rocket hardware.

For those following along, the 3 out of 7 criticism originated in an article by Loren Thompson, a high paid public relations consultant working for Lockeed Martin, Space X rival. First, shipping fuel in advance saves you nothing. In order to manufacture fuel on Mars using the atmosphere you would need a very small 100kw nuclear power source (very doable)about 5tons of preshipped LH feedstock, and a container (could even be the return ship) to store it in. You need about 1kg of hydrogen feedstock shipped from earth to manufacture 20kg of methanol/oxygen fuel, utilizing the CO2 from the martian atmosphere.

Second, using nuclear thermalrockets, or exotic electric propulsion to get you to mars faster doesnt help all that much sinceits wiser to use that additional propulsion to move more cargo and get thereduring the6 month time frame as any return window wont open up for at least 2 years after arriving no matter what, and the additional expense of keeping a ship in space for 2 years (3 with the fast track to mars)operational waiting to return a manned crew is very high risk. Much more risky to the health of passengers is 0g environment, which can be easily mitigated by rotating the crew module with another along a tether. Also, the older the crew, the less impact cosmic or solar radiation will have on them long term.

Also going to the moon doesnt help support this type of mars mission at all since the moon and mars are very very different. Mars has usable in situ resources to make things like fuel from (for now) low quantities of shipped in hydrogen feedstock, and eventually hydrogen extracted from water ice. The moon has none of that, lower gravity, and adding the extra layer of complexity of supporting moon infrastructure is bound to make any mars mission much more expensive and complicated than it has to be.

If Elon Musk says we can get there and back for $500k, I dont think it would be too much of a strech to be able to get passengers, in the far future, to Mars permanently as a colonist for around that figure. Thats the price of a decent house in the US and is definitely doable.

Becausethefaster you get there the morethrust you need and more mulberry sale fuel, especially to slow down. Having a ship travelingwith a deltav of 3.5km/s can be slowed down using aerobraking in the Martian atmosphere and also would allowfor a free return trajectory should landing be impossible. Having a ship travelto marsin 30 days would have to be traveling over 7km/s, far too fast for aerobraking requiring more fuel to slow the ship down and making free return impossible.

If Space X goes by the Mars Direct plan in some fashion, then refueling on Mars is simply the task of converting the carbon dioxide in its atmosphere into methane.

This would mean an initial unmanned ship would be sent first to draw in carbon dioxide and produce methane through the Sabatier reaction (by bringing an initial small mass of hydrogen to Mars.) The same plant could also produce water and air for the coming astronauts the need of stocking too much mass for crew supplies on the way to the Red Planet and on its surface.

Such a process is called Situ Resource Utilization (ISRU) and is very popular among space mission architectures to any planetary body.

Unlike the older comments which comically mention the use of such fuel is scarce off Earth. Should Space X decide to allow their Merlin engines to use methane as well as kerosene or hydrogen, then the plan of settling the Red Planet according to Musk becomes all the more feasible.

I am very skeptical about this it costs NASA and ESA billions to get to Mars. And its not like the people working for them are anything less than some of the best scientists in the world. Unless this company have a serious scientific breakthrough, i don see how it can be done.

I read a quote once that said its more difficult to land on Mars than it is to throw a basketball from one side of America to the other, and have it land in a hoop without touching the sides!

Mars gravity is high enough to have an atmosphere, which makes it difficult to fire rockets on the descent, so parachutes, right? No, because the atmosphere is too thin to slow you down enough, terminal velocity is really really high still. So they have to use a combination of rockets, parachutes and air bags. Compared to the Moon, Mars is much harder to land on.

And as much as i love Space, and dream of going there, i have to say that pretty much everything out there is designed to kill you. Our own Sun is lethal to us without our atmosphere! Mars is a very unforgiving place, one small mistake in those months could cost you your life. And the isolation is pretty severe it takes a few minutes for communication via radio to get to the Earth.

And then when you actually there, what are you planning on doing? Walking around on the surface of Mars in a space suit? Not my idea of fun really. Its just mud and rocks, and its cold and dark too, the Sun is so far away.

We need a warp drive, or some other technological breakthrough so we can visit other stars. That when the real fun starts! Second Earths, possible aliens etc. Much better than visiting dead rocks in our solar system.

course we need better technology, but why wait until this happens? Why did we let 40+ years pass after landing men on the moon? Some say at the time risks were taken to achieve an objective that is always the case to get ahead. Today we can reduce risks on all levels, but not eliminate them totally. Even commercial air travel today is NOT without risks!

As to NASA and ESA, typically government agencies are very inefficient, due to a multilevel hierarchical organizational mulberry sale structure, so cost is always disproportionally high. Musks corporate hierarchy is flat, waste of resources is low, consequently such organization is much more efficient.

mulberry sale Spacesuit future looks sleek

Spacesuit future looks sleek

NASA has learned the hard way that water is an extra slippery customer in space. Water leaking around fan blades in a spacesuit life support system almost caused an astronaut to drown last July, according to a report the US space agency released yesterday.

Thankfully, Luca Parmitano, who was outside the International Space Station when he reported feeling water on the back of his head, abandoned the spacewalk in time and made it back inside. NASA now says the likely cause of the leak was that a water separation pump became clogged, causing water to back up and flow into the suit’s air vents something its engineers had not anticipated.

The agency also revealed that the same suit had leaked only days before. At the time it was put down to a m mulberry sale inor problem with the suit’s bag of drinking water, one that posed no barrier to the suit being used again by Parmitano.

The malfunction highlights the complexity of spacesuits, which are much, much more than souped up clothing. The type of suit Parmitano wore has been in use for 35 years, but now space garb may mulberry sale be on the brink of a transformation. From NASA “suitports” to designs from emerging commercial players, we bring you three things that look set to transform spacewear.

Suitport: Just jump in and spacewalk(Image: NASA)

Taking into account other cases of spacesuit glitches, NASA is currently honing its next generation suits, called . The focus of the first prototype the Z 1 (above) is easy dressing and undressing.

Existing suits have soft legs and a hard fibreglass upper body, which are tough to put on and take off. Rather than being worn on and pressurised inside a spacecraft, the Z 1 would be mounted to the outside of the craft. Astronauts would simply slide through a hatch into the back of the Z 1, then close the hatch behind them and spacewalk away.

The technology that makes the Z 1’s “suitport” possible also shortens the time it takes for an astronaut to get used to breathing the purer air inside. That means astronauts can more quickly be suited up and ready to explore. De suiting is also easy: returning explorers would self dock with the craft and slip back out especially helpful if things go wrong during a spacewalk, as they did for Parmitano.

Sadly, the suitport won’t be headed to the ISS any time soon, as you would have to change the configuration of the station’s airlocks to use it, says Philip Spampinato at ILC Dover in Frederica, Delaware, the company working on the Z series for NASA. The Z series is a kind of testbed for several concepts that are being developed in parallel. The first sample of the next in the series, the Z 2, should be delivered to NASA by the end of 2014, says Spampinato. A flight ready suit won’t be ready until 2020 at the earliest.

Spacesuits aren’t just for spa mulberry sale cewalks: they can also help astronauts inside the ISS. Next year the space station should welcome its first “skinsuit” a sleek spandex affair that looks something like a futuristic wetsuit. Named the Gravity Loading Countermeasure Skinsuit (above), it was designed by researche mulberry sale rs at the Massachusetts Institute of Technology, with the support of the European Space Agency.

The skinsuit is meant to squeeze an astronaut to create pressure, mimicking the way Earth’s gravity affects the body. The idea is that wearing the suit should counterbalance some of the effects of weightlessness, such as muscle loss and weakening bones.

Researchers at MIT and King’s College London have worked on various iterations of such a suit for a decade, and one is finally close to going into space. Danish astronaut Andreas Mogensen will try it out when he heads for the ISS in September 2015.

Commercial outfitters: watch this space

We all know that these days, government agencies aren’t the only game in space, so will private enterprise shake up spacesuit technology just as it could revolutionise space flight and exploration?

ILC Dover is hoping to share its spacesuit smarts with commercial firms vying to launch astronauts into space, either as tourists or to do work on board space shuttle replacements, on behalf of NASA. These companies’ plans do not include spacewalks, at least in the short term, so their suit specifications are different. “The commercial guys are only looking for suits that stay inside the vehicle. All they are doing is carrying people up and down, so that’s a different beast,” says Spampinato.

Commercial space flight firm SpaceX plans to send astronauts to the ISS using a modified version of its Dragon capsule, which already ferries supplies there. The firm recently posted a job opening for a spacesuit engineer. Spokesperson Hannah Post confirmed the company is developing its own suit, but says it is not ready to share details.

Clarification: Since this article was first published on 27 February 2014, it has been updated to recognise the role of King’s College London in developing the Gravity Loading Countermeasure Skinsuit.
