Big Picture Science - As You Were

We all want to turn back time. But until we build a time machine, we’ll have to rely on a few creative approaches to capturing things as they were – and preserving them for posterity. One is upping memory storage capacity itself. Discover just how much of the past we can cram into our future archives, and whether going digital has made it all vulnerable to erasure.

Plus – scratch it and tear it – then watch this eerily-smart material revert to its undamaged self. And, what was life like pre-digital technology? We can’t remember, but one writer knows; he’s living life circa 1993 (hint: no cell phone).

Also, using stem cells to save the white rhino and other endangered species. And, the arrow of time itself – could it possibly run backwards in another universe?

Geomagnetic Storm Sparks Bright Auroras


Source - Space Weather News for Oct. 13, 2012:http://spaceweather.com

GEOMAGNETIC STORM: A  persistent G1-class geomagnetic storm on Oct 13th (still underway as this alert is being written) has sparked bright auroras around the Arctic Circle, spurring reports of Northern Lights from Scandinavia, Greenland, Canada, and several northern-tier US states.  More auroras are in the offing. NOAA forecasters estimate a 40% chance of continued storms on Oct. 14-15 in response to a high-speed stream of solar wind. Check http://spaceweather.com for images and updates.

Draconid Meteor Outburst Underway


Source - Space Weather News for Oct. 8, 2012: http://spaceweather.com

METEOR OUTBURST: Radars in Canada are reporting a major outburst of Draconid meteors commencing at 16 UT on Oct. 8th. "Radar rates are at 1000 meteors per hour," says Bill Cooke of NASA' Meteoroid Environment Office. "This is greater than last year's outburst, and 5x the 2005 level."

Cooke encourages northern sky watchers, especially in Europe where night is falling, to be alert for Draconid activity.  Because radars are sensitive to very small meteoroids, there is no guarantee that this radar outburst will translate into meteors visible to the human eye.  On the other hand, a brilliant display could be in progress.  The only way to know is to go outside and look.  Check http://spaceweather.com for more information and updates.

Should we celebrate Columbus Day or Exploration Day?


Recently I watched a hangout on Google+ where Nicole Gugliucci of CosmoQuest interviewed Tom Diehl about a proposal he is involved with to rededicate Columbus Day to Exploration Day, and within minutes of watching the hangout and listing to Tom I was hooked on the idea.

Tom Diehl along with Karl Frank and Dr. Rod Wright are putting forth a proposal that Columbus Day be rededicated as Exploration Day. You may ask why should Columbus Day be rededicated as Exploration Day? Well in my opinion this quote from Karl Frank in this Discovery.com article best sums up the rationale behind the proposal:

"Rededicating Columbus Day as Exploration Day will allow those who wish to commemorate his accomplishments to continue doing so," says Frank. "But for those who find Columbus's role in history disquieting, it will enable them to celebrate the day in a very different way. Exploration Day covers the depth and breath of America’s rich history of exploration, research and discovery. Thus, Exploration Day will be something that unites rather than divides." (1)

That quote drives home the one point that I really like about the Exploration Day proposal, and that is that Exploration Day would be an all inclusive celebration of exploration that anyone in the US can embrace. Also given that the holiday would be near the start of the school year it would also be a great springboard to get students more involved in exploring science, technology, engineering, and math; also known as STEM.

Below is the video of the Google+ hangout Nicole Gugliucci, and Tom Diehl that is well worth watching. I am hopeful that once you watch the video and check out the included links to the Exploration Day web site, and several articles, you too will also be a supporter of Exploration Day:

NASA AND INTERNATIONAL PARTNERS APPROVE YEAR-LONG SPACE STATION STAY


Source - http://www.nasa.gov for Oct. 5, 2012 - RELEASE: 12-354

NASA AND INTERNATIONAL PARTNERS APPROVE YEAR-LONG SPACE STATION STAY

WASHINGTON -- NASA and its international partners have announced an agreement to send two crew members to the International Space Station on a one-year mission designed to collect valuable scientific data needed to send humans to new destinations in the solar system.

The crew members, one American astronaut and one Russian cosmonaut, will launch and land in a Russian Soyuz spacecraft and are scheduled to begin their voyage in spring 2015.

The space station serves as a laboratory for technological demonstrations and scientific research, including experiments that improve understanding of how the human body reacts and adapts to the harsh environment of space. Data from a year-long expedition also will help inform assumptions about crew performance and health, and will help reduce the risks associated with future exploration.

"In order for us to eventually move beyond low Earth orbit, we need to better understand how humans adapt to long-term spaceflight," said Michael Suffredini, International Space Station program manager. "The space station serves as a vital scientific resource for teaching us those lessons, and this yearlong expedition aboard the complex will help us move closer to those journeys."

During the 12 years of permanent human presence aboard the space station, scientists and researchers have gained valuable, and often surprising, data on the effects of microgravity on bone density, muscle mass, strength, vision and other aspects of human physiology. This year-long stay will allow for greater analysis of these effects and trends.

"We have gained new knowledge about the effects of spaceflight on the human body from the scientific research conducted on the space station, and it is the perfect time to test a one-year expedition aboard the orbital laboratory," said Julie Robinson, NASA's program scientist for the International Space Station. "What we will gain from this expedition will influence the way we structure our human research plans in the future."

The expedition also will serve as a test bed for future exploration technologies. Those innovative technologies, the logistics of the trip to and from the space station and the selection of the crew will be announced at a future time.

Draconid Meteor Shower

DRACONID METEOR WATCH: Earth is about to pass through a stream of debris from comet 21P/Giacobini-Zinner, source of the annual Draconid meteor shower.  Last year, Europeans witnessed a faint but furious outburst of 600 meteors per hour when the shower peaked.  No such display is expected this year, but the Draconids are notoriously unpredictable.  Northern-hemisphere sky watchers should be alert for slow-moving meteors emerging from the head of the constellation Draco the Dragon (not far from the North Star) on Sunday night, Oct 7th, through Monday morning Oct. 8th. Check http://spaceweather.com for more information and updates.

INCOMING CME:  A coronal mass ejection (CME) is heading for Earth.  The incoming cloud is expected to deliver a glancing blow to our planet's magnetosphere on October 8th, possibly sparking auroras at high latitudes.  Would you like a phone call when the CME arrives?  Geomagnetic storm alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).
