This is why Elon Musk wanted to avoid Parachutes
Posted by Bill D’Zio in categories: engineering, space, space travel
By Bill D’Zio Originally published on www.westeastspace.com
Parachutes are plaguing space programs. SpaceX doesn’t like Parachutes. They are difficult to design, hard to package, and easy to damage. The larger the mass of the spacecraft, the more effort to slow down. Larger, more efficient, complex parachute systems are needed. Several failures have hit the industry over the last few years, including SpaceX Crew Dragon, ESA ExoMars, Boeing CST-100, and the NASA Orion to name a few.
How do parachutes work and why are they hard?
The idea of a parachute is simple. All falling objects fall the same when under the same conditions… that is so long as no outside force is exerted on it. So two objects dropped from the same altitude, one a feather and hammer will fall equally. Don’t believe me? NASA tested it on the Moon. During Apollo 15 moon walk, Commander David Scott performed a live demonstration for the television cameras. Commander Scott did the Apollo 15 Hammer and Feather test. He held out a geologic hammer and a Falcon feather and dropped them at the same time. Because there is not an atmosphere on the Moon, they were essentially in a vacuum. With no air resistance force, the feather fell at the same rate as the hammer. Ironically, Apollo 15 had a second demonstration of falling objects when one of the parachutes failed to function as planned.
On Earth, and any other planet with an atmosphere, air acts as a resistance force for an object moving through it. We can get more air resistance force by increasing the surface area. Depending on the shape of the object, it’s orientation, and the amount of resistance will increase, and therefore slow the object down. Unbalanced and uncorrected resistance can cause the object to start to turn, twist and tumble. A parachute system is deployed to generate air resistance from the atmosphere. (note that the thicker the atmosphere the more resistance) Parachutes designed for use on Earth will not be the same as a parachute designed for Mars.

Clinical trials may begin next week in New York for coronavirus treatments: Health official
Posted by Omuterema Akhahenda in categories: biotech/medical, health
Officials are working out final details in plans to begin clinical trials next week for a malaria drug combination that appears to hold some promise for confronting the coronavirus pandemic.
New York state Health Department officials are making arrangements to determine what patients at which hospitals will be allowed to participate in trials with hydroxychloroquine, Zithromax and chloroquine, a senior official at the department with knowledge of the plan told ABC News. The bulk of the patients are expected to be in the New York City metro area because the region has the biggest cluster of cases.
New York Gov. Andrew Cuomo announced earlier this week that he was eager to get the trials started. By Tuesday, the drugs were in New York and officials were working to identify who could participate.

Israel preparing to use unapproved medication to treat coronavirus
Posted by Omuterema Akhahenda in category: biotech/medical
As for coronavirus patients in serious condition, the ministry proposed – in addition to treating respiratory failure and supportive treatment – using Gilead’s drug Remdesivir, which was used in the case of Patient 16. The 38-year-old bus driver from East Jerusalem was in serious condition and the drug improved his situation dramatically, so much so that he was in good condition after the treatment.
They said that research into treating the virus is only in the research stage since the virus was only discovered some months ago.

Israeli scientist’s shrimp antiviral could be adapted for coronavirus
Posted by Omuterema Akhahenda in categories: biotech/medical, engineering, food
The 43-year-old scientist is a member of the Technion’s Wolfson Faculty of Chemical Engineering, and his lab first developed a food additive to boost the immune system of animals to protect them from contracting viral diseases. This invention formed the basis of his own commercialized start-up company, ViAqua Therapeutics, which focused the development of the drug on shrimp, as over 30% of the global shrimp population is wiped out yearly by a viral disease known as white spot syndrome.
Israeli scientist and entrepreneur Prof. Avi Schroeder is working on a preventative drug for the coronavirus by adapting a food additive designed for shrimp.

Samsung brings cutting-edge ultraviolet light technology to DRAM production
Posted by Quinn Sena in categories: computing, electronics
Samsung Electronics today announced it will be introducing the first DRAM memory modules in the industry designed with cutting-edge Extreme Ultraviolet Technology (EUV).
One of the world’s leading memory manufacturers, Samsung says that response to a million evaluation units of its first line of 10nm-class DDR4 DRAM modules has been positive and that it will soon begin processing orders for worldwide distribution.
EUV technology allows memory modules to be manufactured more accurately and more quickly. It speeds up the lithography process by reducing the number of repetitive steps and facilitates the production of complex chip patterns. It means greater performance accuracy and a shortened development time.
