I’ll Be Appearing At The New York Travel Festival, Speaking About Adventure Travel in Antarctica

Jeffrey Donenfeld Ask Me Anything, Events, Press Leave a Comment

This year, the New York Travel Festival is taking place April 26-27, 2014 in New York City. I've been selected by the organizers to act as the resident expert on Antarctica.  Read my bio on the NY Travel Festival website.  The New York Travel Festival aims to reinvent the consumer travel show for tech-savvy, immersive travelers. We go beyond booths and brochures to provide interactive experiences to people who see travel as a means of experience, not just escape. NY Trav Fest brings together a unique blend of consumers, media and industry to mingle and discuss the future of travel together. Here's what I'll be up to during the event: Pre-show: Travel Babel Intro Video Saturday, April 26 Expert's Corner - Meeting with general public andanswering questions about Adventure Travel in Antarctica. BOOK MY TIME FOR THIS SESSION Sunday, April 27 Antarctica Trivia Round, 12-1pm ADD TO CALENDAR Antarctica Talk and Slideshow, 3-4pm:  "Surviving the world’s highest, coldest, windiest and driest desert — Antarctica" ADD TO CALENDAR NY Travel Festival Full Official Schedule (Bio on Sched) Get your tickets now and come see me in April - use these promo codes: Code 'JEFFZILLA' $30 Weekend Consumer (instead of $35) Code 'JEFFIND' $80 Weekend Industry (instead of $100) Purchase Tickets

Happy Thanksgiving!

Yes, we have Thanksgiving even at the South Pole. In honor of the holiday, the station got together and prepared a tasty traditional meal. Afterwards, we went down to “lolo” – an underground maintenance bunker, to celebrate and dance. A few pics from the festivities…

Learning About Space Suit Design With Astronaut Joseph Tanner

Jeffrey Donenfeld Events, Science Leave a Comment

This past week, my brother Jason and I were fortunate enough to be allowed to sit in on a guest lecture at the University of Colorado Engineering Center by NASA Astronaut Joe Tanner. Joe spoke to us about the ins and outs of spacesuit design, and shared a bunch of his personal stories. A pic or two, as well as my brief notes: Space Habitat Design  - ASEN 5158 Notes Main challenges of EMU – refurbishment of the suit after every flight. Now on ISS, suits left on station for a long time – like 6 months. modular components EMU – on extended EVA’s, it’s necessary to resupply suit halfway through – takes 5 minutes minutes to refil o2. Limiting consumable on EMU is the co2 scrubbing system After Ed White’s gemini EVA, training focus was switched to underwater training Apollo EVAs Umbilical based to pick up film from outside of module no cooling system Backpack – SOP – Secondary o2 pack Apollo Lunar walk SOP Very high center of gravity because of high location of SOP STS SAFER – cold gas jet mechanism for navigating in space. Suited Environments Launch, Entry and Abort – must be able to operate flight controls, as well as emergency depress/egress Orbital – shirts and shorts, unless on TV, then nasa wants the astronauts to wear long pants. Lunar/Mars – main concern is the dust – will eat the suit alive! NEO’s – Biggest problem is body stabilization Suit Functional Requirements Environmental control and live support parameters Maintain Pressure Remove co2 Provide o2 thermal control humidity control trace contaminant control mmod/radiation protection food/water water is space suit is tube with actual bite valve from Camelbak waste mobility/dexterity ORLAN Russian Spacesuit In use for 40+ years, still in use today. Pressurized at 5.7 psi suit, which makes an easier transition from cabin to eva, but makes hand dexterity more difficult. Delta p Concerns Getting from cabin pressure to suit pressure – issues include decompression sickness, bends, etc Prevented by lowering cabin pressure, lowering N2 content in atmosphere, or lowering n2 content in human. Prebreathe protocol – facilitate equilibrium Zero prebreathe is at 8.3 psi Haldane’s Ratio – Defines cabin/suit pressure ration based on risk of DCS

Curiosity Rover Successfully Lands On Mars!!

Congratulations to the NASA/JPL-Caltech crew for successfully landing the Mars Science Laboratory’s Curiosity Rover on Mars! Here are the first images taken by Curiosity on the red planet.. NASA Administrator Charles Bolden’s statement: NASA is back on Mars – and getting ready for the next mission to the Red Planet! After an astounding 154 million mile journey and a harrowing landing that demonstrated cutting-edge technology, Curiosity, the largest rover ever sent to another planet, is in place and ready to work. This robotic laboratory will seek answers to one of humanity’s oldest questions as it investigates whether conditions have favored development of microbial life on the Red Planet. The mission is a critical planetary science mission — and a precursor to sending humans to the Red Planet in the 2030’s, a goal set forth by President Obama. It’s another great leadership moment for our nation and a sign of the continued strength of NASA’s many programs in science, aeronautics and human spaceflight. It’s also important to remember that the $2.5 billion investment made in this project was not spent on Mars, but right here on Earth, supporting more than 7,000 jobs in at least 31 states. With the retirement of the Shuttle program after its final flight in July 2011, some have suggested that NASA’s leadership in the exploration of space, including our extraordinary successes on Mars, was coming to an end. Nothing could be further from the truth. The Curiosity mission is only the latest in a long list of extraordinary NASA missions that established the United States as the undisputed world leader, and it will help guarantee that remains the case for many years to come. When our Orion deep space crew vehicle takes its first test flight in 2014, it will travel farther into space than any spacecraft designed for humans has flown in the 40 years since our astronauts returned from the moon. In 2017, NASA’s Space Launch System (SLS), a heavy-lift rocket that will provide an entirely new capability for human exploration beyond low Earth orbit, will launch Orion. We also reached a critically important milestone in May when SpaceX became the first private company to send a spacecraft — the Dragon cargo capsule — to the International Space Station and return it with cargo intact. This successful mission ushered in a new era in spaceflight — and signaled a new way of doing business for NASA. And just a few days ago, we announced the next step in the Obama Administration’s aggressive plan to once again launch our astronauts from U.S. soil on spacecraft built by American companies. As part of our commitment to maintain American leadership in the exploration of Mars beyond the Curiosity mission, NASA will launch the Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiter next year. Earlier this year, I directed NASA’s science mission director, along with the head of human exploration, Chief Technologist, and Chief Scientist to develop a more integrated strategy to ensure that the next steps for Mars …
