Dragon capsule returns to Earth after Space station delivery

A SpaceX Dragon freight send left the International Space Station and came back to Earth Saturday (Jan. 13), wrapping up an about month-long conveyance mission for NASA that likewise denoted the rocket’s second trek to space.

The uncrewed Dragon supply transport isolates from the space station’s mechanical arm at 4:58 a.m. EST (0958 GMT) and started terminating thrusters for its arrival to Earth. The space container sprinkled down in the Pacific Ocean off the bank of Baja California to be recovered by SpaceX, the organization reported at 10:39 a.m. EST (1539 GMT).

“Great splashdown of Dragon affirmed, finishing the second resupply mission to and from the @Space_Station with a flight-demonstrated business rocket,” SpaceX delegates said in a Twitter refresh.

Mythical serpent is conveying about 4,100 lbs. (1,860 kilograms) of payload to Earth, a lot of it science outfit from human and creature inquire about, and different investigations. That rigging incorporates equipment from an analysis by space producing organization Made In Space to 3d-print ZBLAN glass fiber optic wire in space, and a gathering of live mice from NASA’s Rodent Research 6 concentrate to create prescriptions that address muscle misfortune in space., NASA authorities said.

A SpaceX Falcon 9 rocket propelled the Dragon mission on Dec. 15, with the container landing at the International Space Station on Dec. 17. The mission, SpaceX’s thirteenth resupply flight for NASA, conveyed 4,800 lbs. (2,177 kilograms) of provisions and rigging for space travelers.

Notwithstanding conveying freight, the mission denoted a turning point for SpaceX’s rocket reusability program. Both the Dragon case and its Falcon 9 promoter made their second treks to space on this flight. The Falcon 9 sponsor’s first stage already propelled an alternate Dragon container to the space station in June 2017. The Dragon case on this flight, in the mean time, beforehand went by the space station in April 2015.

Euthanasia campaigner Dr Philip Nitschke invents Sarco suicide capsule with 3D printer

Nov 24, 2017 | By David

We know that 3D printing technology can produce all kinds of devices and products for the treatment of people suffering from various medical problems that are often life-saving, but what about those not looking to save their life but to end it? This apparently counter-intuitive medical function could become more and more important as euthanasia becomes increasingly acceptable and common around the world, and a recent 3D printing breakthrough made by a controversial Dutch assisted dying expert looks well-placed to take advantage of the potential suicidal spread.

Dr.  Philip Nitschke, a well-known proponent of euthanasia who has been given the nickname “Dr. Death,” created this suicide machine using 3D printing technology. It’s known as the Sarco capsule, and was developed alongside engineer Alexander Bannink. The machine allows users to kill themselves easily and painlessly with the single press of a button. The plan is for the 3D printing files to be made open-source and available online for free, in order to allow anyone with access to a 3D printer and a death wish to download digital designs for their own death-dealing device.

Dr Nitschke told The Weekend Australian that “the limit will be the availability of the new 3D printers.” His team is “looking at printing (it) using biodegradable wood and plastic for the capsule. Printing materials are readily available (in Australia) as is liquid nitrogen. Printing cost is only an estimate at this point, but probably around 1000 ($1500)”.

According to Nitschke, “Sarco does not use any restricted drugs, or require any special expertise such as the insertion of an intravenous needle… Anyone who can pass the entry test can enter the machine and legally end their life.”

The entry test he refers to is an online questionnaire, which is intended to assess the mental wellbeing of potential users, in order to judge whether or not they are a suitable candidate for taking their own life. Based on the results of this psychological test, the user may or may not be given a 4-digit code, which needs to be entered a keypad inside the Sarco capsule for it to carry out its solemn duty.

The Sarco terminates the existence of its users by releasing liquid nitrogen inside its sealed capsule, which gradually reduces the oxygen level until breathing, and survival, are no longer possible. The capsule can then be detatched and used as a coffin, while the base can be re-used by another person who has chosen to shuffle off this mortal coil.

Nitschke previously released a suicide kit online which was disguised as equipment for home brewing beer. This sold for roughly $340 and was available in the UK for over three years. Before becoming one of the world’s most infamous euthanasia activists, Nitschke was a doctor practicing in Australia. He got into hot water with the law after neglecting to refer a suicidal patient, who eventually committed suicide, to a psychiatrist. This affair caused him to burn his medical license and set up the assisted suicide campaign Exit International. His work has apparently been prompted by growing demand for choices by the elderly and an ageing population, as well as difficulties associated with sourcing the best drugs to end a life safely and comfortably.

The Sarco is undeniably a disruptive solution to many problems facing the medical industry and society at large, albeit a controversial one. It is due to be demonstrated (presumably not with an actual human subject) at this year’s Exit NuTech Conference “New Technologies for a Peaceful DIY Death”, which wil be held in Toronto on Sat 28th October.

(In the UK and Republic of Ireland, the Samaritans can be contacted on 116 123. In the US, the National Suicide Prevention Lifeline is 1-800-273-TALK. In Australia, the crisis support service Lifeline is on 13 11 14)

SpaceX uses 3-D printing to build bigger, better Dragon capsule

If astronauts start riding SpaceX’s Dragon space capsule to the International Space Station (ISS) in a few years as anticipated, they will have 3-D printing businesses down on Earth to thank for it. This fast-growing manufacturing niche is already responsible for making many of the parts on the spaceflight company’s existing Dragon 1 much more affordably and rapidly than would otherwise be the case.

SpaceX has a long-term contract with NASA to deliver cargo to the ISS and, eventually, personnel. It is carrying out the cargo part now using its Dragon version 1, an unmanned space capsule that has made several runs to the space station and back over the past year. The company is working now on the Dragon version 2, which will have seats for seven human passengers.

And meantime, Dragon version 1 is a great test case in how 3-D printing can aid spaceflight. A 3-D printing process known as additive manufacturing is how engineers constructed a portion of the engine thrusters that the Dragon is using to self-land. In a press conference earlier this year, SpaceX CEO Elon Musk gave credit to the German companies EOS, SLM Solutions, and Concept Lasers for developing the additive manufacturing process.

The future Dragon version 2 will have a more powerful engine, called the SuperDraco, which it will use for landing. Additive manufacturing is how the SuperDraco’s parts will be constructed, too. SpaceX will produce these huge thrusters in-house, using printer systems to fashion part after part from a metal substrate.

3-D printing involves a “printer” emitting layers of particles one at a time atop each other to build a solid product particle by particle. Computer, automotive, and airplane manufacturers are finding growing uses for it. And now spaceflight manufacturing is following suit.

“Through 3D printing, robust and high-performing engine parts can be created at a fraction of the cost and time of traditional manufacturing methods,” said Musk in a statement. “SpaceX is pushing the boundaries of what additive manufacturing can do in the 21st century, ultimately making our vehicles more efficient, reliable and robust than ever before.”
