NASA unveils space suit fit for Mars
Z-2 prototype is the latest design in next-generation astronaut apparel
by Andrew Grant 7:26am, June 27, 2014
Though its styling suggests 1980s sci-fi, NASA’s newly revealed Z-2 space suit is the astronaut apparel of the future. It is the second mock-up of a suit that NASA hopes will eventually protect explorers walking on Mars or drilling into an asteroid. “Space suit design is predicated on where you’re going and what you’re doing,” says Amy Ross, a space suit designer at the Johnson Space Center in Houston.
As a result, one of the Z-2’s most important features is its lower-body flexibility, which allows astronauts to walk, climb and crouch to explore extraterrestrial landscapes. By November, NASA should have a prototype ready for testing, complete with Tron-like, blue luminescent patches that were selected by the public in an Internet poll. Unfortunately, those aesthetics won’t appear on the final version of the suit, which NASA hopes to have ready for launch by 2018.

On Jun. 7, 2014, U.S. Marine Corps Capt. William Mahoney, Marine Medium Tiltrotor Squadron (VMM) 263 (Reinforced), 22nd Marine Expeditionary Unit (MEU), had to perform Vertical Landing on USS Bataan, after his AV-8B Harrier aircraft experienced a front landing gear malfunction.
USS Bataan was operating in the U.S. 6th Fleet area of operations to augment U.S. Crisis Response forces in the region when Mahoney took off from the amphibious assault ship.
As he was climbing away from the deck he suddenly realized he had a gear malfunction. He immediately slowed down in order not to overspeed the landing gear, returned above the ship at 2,000 feet and started talking to "Paddles" (LSO -- Landing Signal Officers), a pilot in the control tower who could provide assistance by radio.
GOOD MORNING CRYSTAL ~ PURR ~ SYS ~ JJ ~ HAL ~ FLAT ~ WELL....
Unsuspecting parents took their babies to watch parts of the Uruguay-Italy World Cup Brasil match on Dutch telly.
A great saturday afternoon, ZETAR, Crystal and to all those putting so much heart and effort into stuff, and hardly any nonsense of course!
Serious stuff next from the World Cup Brasil biting incident, Luis Suarez (now severely disciplined) getting a taste of opponent Italy, a shocking and incomprehensible action now propagating out across world and internet.
The immensely popular Hup Holland Hamsters, 23 varieties distributed to customers of Dutch mega grocer Albert Heijn.
In the Netherlands lots of families innocently have been taking their babies into first halves of these exciting soccer duels, many of our living rooms adorned with various 'orange' paraphernalia, items expressing support for the Dutch team, especially the Hup Holland Hamsters, 23 varieties distributed by Dutch mega grocer Albert Heijn. Then Suarez bit down.
After his bite foul, Uruguay striker Luis Suarez adhering to the time honored tradition of overdone soccer theatrics, fell down writhing in apparent agony, holding his front teeth, perhaps to suggest to the referee that Italian player Giorgio Chiellini actually had fouled him(!) by pushing his shoulder into his mouth.
And now there's a national scare of babies going after these hamsters copycat fashion and biting off their little round back stickers. Albert Heijn is worried, even alerting the national media, because there's a real danger of suffocation for young children. Dutch parents have been put on high alert!
"..a word of advice straight frorm the cat's mouth to yar ear, ah Luis, always remember to brush twice daily, got to keep your weapons clean, and before delving into any meal check whether it's well cooked, and (my preference) a fowl. Never ever into stuff conceivably called Giorgio, or a Foul..!"

Nasa lands saucer-shaped vehicle in test of technology for landing on Mars
Vehicle with giant 'puffer fish' parachute takes flight in $150m experiment over Hawaii, designed to test technology for Mars
Associated Press theguardian.com, Sunday 29 June 2014 09.20 EDT
A saucer-shaped Nasa vehicle launched by balloon high into Earth's atmosphere splashed down in the Pacific Ocean on Saturday, completing a successful test of technology that could be used to land on Mars.
Since the twin Viking spacecraft landed on the red planet in 1976, Nasa has relied on the same parachute design to slow landers and rovers after piercing through the thin Martian atmosphere.
The $150m experimental flight tested a novel vehicle and a giant parachute designed to deliver heavier spacecraft and eventually astronauts.
Despite small problems such as the giant parachute not deploying fully, Nasa deemed the mission a success. "What we just saw was a really good test," said Nasa engineer Dan Coatta with the Jet Propulsion Laboratory in Pasadena, California.
Viewers around the world with an internet connection followed portions of the mission in real time thanks to cameras on board the vehicle that beamed back low-resolution footage. After taking off at 11.40 am from the Pacific Missile Range Facility on the Hawaiian island of Kauai, the balloon boosted the disc-shaped vehicle over the Pacific. Its rocket motor then ignited, carrying the vehicle to 34 miles (55km) high at supersonic speeds.
The environment at that altitude is similar to the thin Martian atmosphere. As the vehicle prepared to drop back the Earth, a tube around it expanded like a Hawaiian puffer fish, creating atmospheric drag to dramatically slow it down from Mach 4, or four times the speed of sound.
Then the parachute unfurled and guided the vehicle to an ocean splashdown about three hours later. At 110 feet (33 meters) in diameter, the parachute is twice as big as the one that carried the one-tonne Curiosity rover through the Martian atmosphere in 2011.
The test was postponed six times because of high winds. Winds need to be calm so that the balloon does not stray into no-fly zones.
Engineers planned to analyze the data and conduct several more flights next year before deciding whether to fly the vehicle and parachute on a future Mars mission. "We want to test them here where it's cheaper before we send it to Mars to make sure that it's going to work there," project manager Mark Adler of the Nasa Jet Propulsion Laboratory said during a pre-launch news conference in Kauai in early June.
The technology envelope needs to be pushed or else humanity won't be able to fly beyond the International Space Station in low-Earth orbit, said Michael Gazarik, head of space technology at NASA headquarters.
"Technology development is the surest path to Mars" Gazarik said at the briefing.
