NASA Proves Building Blocks Of DNA Come From Space. "NASA researchers studying meteorites have found that they contain several of the components needed to make DNA on Earth. The discovery provides support for the idea that the building blocks for DNA were likely created in space, and carried to Earth on objects, like meteorites, that crashed into the planet’s surface. According to the theory, the ready-made DNA parts could have then assembled under Earth’s early conditions to create the first DNA."
NASA's Juno spacecraft launched this morning and is en route to Jupiter (launch video). Equipped with microwave, ultraviolet, infrared, and visible light detectors Juno will investigate the origins, atmosphere, and magnetosphere of the Solar System's largest planets over one year beginning with its arrival in 2016. Using its awesome solar-powered technology Juno will show Jupiter's magnetic field in detail never before seen. We probably won't hear much from Juno again until 2013, when it makes a fly-by of Earth. You can follow Juno on Twitter, so if it types out its scream, someone will hear it. Also
screaming traveling aboard Juno are three very special LEGO mini-figurines.
The Mix Tape of the Gods: made to be played at 16-2/3 revolutions per second, now traveling 300 million miles per year
August and September 2011 mark 34 years in the journeys of Voyager 1 and 2. The two scientific probes, progeny of the Mariner program, were sent out to survey this solar system and beyond. Voyager 2 completed the Grand Tour in 2009 (excluding Pluto), and Voyager 1 is getting closer to interstellar space (previously). Both scientific probes were sent out in with a time capsule from 1977, golden records secured in plain view on the outside of the Voyager Spacecraft. These greetings from earth (alt links: Coral Cache, Archive.org) were recorded in the form of 116 images, a collection of sounds of this planet, greetings in 55 languages (YT), 27 songs from around the world, and brain waves of Ann Druyan, then recently engaged to Carl Sagan. For all that work, the "Mix Tape of the Gods" almost didn't get sent into space because of some last-minute writing in the run-outs. [more inside]
NASA May Have Discovered Flowing Water on Mars Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle latitudes of Mars' southern hemisphere.
Jupiter has lots. Mars has some, too, as does Neptune. Turns out Earth's got a trojan asteroid of its own. Meet 2010 TK7, the blue planet's new baby brother.
Initially the conventional wisdom was that spacesuits “would be like rockets: adamantine, metallic, armored and smooth.” But in practice, rigid spacesuits repeatedly failed under testing. So when Neil Armstrong and Buzz Aldrin walked on the Moon they were protected from the vacuum of space by flexible spacesuits crafted from twenty-one layers of fabric, “each with a distinct yet interrelated function, custom-sewn for them by seamstresses whose usual work was fashioning bras and girdles” for the Playtex Corporation.

Pluto may have been downsized in 2006, but it's still living large, moon wise: A fourth moon has been discovered orbiting the dwarf planet.
Dawn spacecraft now orbits asteroid Vesta - After almost 4 years of space travel, the Dawn spacecraft successfully entered orbit around Vesta, an Arizona sized rock. Dawn tweets, takes pictures, and there is a Vesta Fiesta party to celebrate. After hanging out at Vesta for a year, Dawn will head off to visit the Ceres asteroid next, a three year trip. Amazing achievement of engineering, innovation and accuracy.
On July 5th the SOlar and Heliospheric Observatory (SOHO) captured video of a comet, known as a sungrazer, in route to collide with our star. SOHO is equipped with an occluding coronograph that blocks direct sunlight and reveals the corona, but also prevents direct study of the terminal impact of sungrazers. But on July 6th, with the help of the Solar Dynamics Observatory (SDO), astronomers were able to observe the comet (slyt) streaking in front of the surface of the sun for the first time in history. It likely disintegrated before impact due to extreme heat and radiation.
The Space Shuttle Atlantis, STS-135, is scheduled to lift off this morning from Kennedy Space Center. The time was originally scheduled for 11:26 AM EDT, but that has been pushed back, despite "no technical concerns and... weather is a 'go'." Astronauts aboard are Commander Chris Ferguson, Pilot Doug Hurley, and Mission Specialists Sandy Magnus and Rex Walheim. Watch live coverage, with some archival footage, on NASA's Ustream or on NASA.gov. NASA has provided countdown highlights of the day to get you up to speed. Read NASA's feed on Twitter. At the time of this post's writing, the countdown clock is on a scheduled hold with 9 minutes to go. Previously, STS-134, on the Blue.
Sunspots, first observed by Galileo, normally follow an 11-year cycle. We are into a few years into (recorded) cycle number 24 but according to NASA it's looking rather underpowered. Nobody is certain exactly what the consequences will be, but one distinct possibility is a cold period; a previous low in solar activity, the Maunder minimum, is correlated with a brief Little Ice Age. Nobody really knows how this unusual solar weather pattern might interact with human-caused climate change. Previously, albeit somewhat controversially.
An 'armchair astronomer' named David Martines has found something on Google Mars which he believes is some kind of space station. Allegedly, NASA is investigating the image. Another theory says that what he sees is a "linear streak artifact produced by a cosmic ray".
NASA's Jet Propulsion Laboratory has announced: NASA has ended operational planning activities for the Mars rover Spirit and transitioned the Mars Exploration Rover Project to a single-rover operation focused on Spirit's still-active twin, Opportunity. New Scientist has a quality obituary for the little Mars Rover that could.
On May 16, 2011, after one scrubbed attempt, the space shuttle Endeavour set off on her final mission, STS-134. Shuttle commander Mark Kelly had this to say after receiving a "go" from the launch poll:
On this final flight of space shuttle Endeavour, we want to thank all the tens of thousands of dedicated employees that have put their hands on this incredible ship and dedicated their lives to the space shuttle program. As Americans, we Endeavour to build a better life than the generation before, and we Endeavour to be a united nation. In these efforts, we are often tested. This mission represents the power of teamwork, commitment, and exploration. It is in the DNA of our great country to reach for the stars and explore; we must not stop. To all the millions watching today, including our spouses, children, family, and friends, we thank you for your support.You've seen launches before, but NASA has uploaded a whole slew of angles that will truly amaze: Witness 4.4 million pounds of shuttle, fuel, and rocket boosters "twang" a full 18 inches as the main engines ignite. 1.2 million pounds of thrust push against a locked down stack, waiting for the solid rocket boosters to ignite. (The SRBs bring the total to 7 million lbs of thrust, enough to break all that binds her to the pad.) OTV Camera 71, a fantastic, short close-up. UCS-15 (TV-21A) provides a dead-on, close up shot of the launch. The South Beach Tracker shot offers a fantastic view as well. From 3.1 miles away at the Press Site, note the ~11 second delay before the piercing sound of the SRBs hits. And just released today, fantastic footage from the solid rocket boosters, including their trip to splashdown in the Atlantic ocean from 30 miles up. And finally, the classic NASA view, with some great data overlays by Spacevidcast. [more inside]
50 years ago today, on May 25 1961, US President John F. Kennedy decided "...this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." Eight years later the Apollo program fulfilled the task, leaving the world with a legacy that includes advances in computers and communciation, lessons in managing complex projects, technological innovations and new views of the Earth.

From Earth to the Solar System (FETTSS) is a collection of images curated by NASA that portray an attempt to understand the origin and evolution of the solar system, by looking to the skies and investigating extreme situations on earth, like high-altitude lakes and an acidic river. [more inside]
"There is a space-time vortex around Earth, and its shape precisely matches the predictions of Einstein's theory of gravity." NASA announces result of elaborate experiment to prove Einstein's inferences about space time. The engineering involved in this blows me away. More links within the article...
We tend to think of blogs that showcase large images as a phenomenon of the past few years. But NASA's Earth Observatory has been posting its Image of the Day since April 1999 (when its first "large" image available for download was a 214 KB jpeg of the North Pole). Now, Image of the Day has downloads of images in multiple formats, most of which measure in megabytes, not kilobytes, and these stunning images of the earth's surface give context to the human activity down below: a toxic spill in Hungary, wildfires in Mexico, the growth of a coal mine in West Virginia, agriculture in Brazil, snowmelt flooding in Fargo, North Dakota, last year's oil spill in the Gulf of Mexico, artificial islands in Dubai, the aftermath of Japan's recent tsunami.
Following on the heels of NASA's announcement of the final resting places of the various space shuttles, NASA, in conjunction with William Shatner, released a final video commemorating the program. (SLYT)
After completing it's final mission in March, Space Shuttle Discovery has been returned to the Kennedy Space Center's Orbiter Processing Facility, where it is being dissembled for cleaning and decommissioning. Spaceflight Now has pictures of the process.
For All Mankind "Al Reinert’s documentary For All Mankind is the story of the twenty-four men who traveled to the moon, told in their words, in their voices, using the images of their experiences. Forty years after the first moon landing, it remains the most radical, visually dazzling work of cinema yet made about this earthshaking event." "For All Mankind is irreplaceable: one of a kind and likely to remain so. It is, formally, among the most radical American films of the past quarter century and, emotionally, among the most powerfully affecting. It makes its impossible title stick. In For All Mankind, we all lift off together, and we all come home the same way, and few movies have captured so well the rhapsodic absurdity of our common voyage." 1 :: 2 :: 3 :: 4 :: 5 :: 6 :: 7 :: 8

Scheduled for November 25th, the Mars Science Laboratory - Curiosity Rover will launch on an 8.5 month journey to Mars. Upon arrival, it will plummet through the atmosphere in a flying-saucer-like aeroshell and execute a most unusual landing via skycrane. Curiosity carries a dizzying array of cameras and sensors, but more importantly a high powered laser to teach Mars who is boss, and oh, maybe your name if you let it.
$1,000 per pound to orbit is the holy grail for rocket pricing. Elon Musk claims that his SpaceX corporation's new Falcon Heavy will be able to lift 117,000 lbs. to low earth orbit for 1/3rd the cost of the next most capable launchers, the space shuttle and the Delta IV Heavy. [more inside]

"The theme of this blog is not only and obviously space, but in particular places in space that a person might theoretically be able to one day visit. So for the most part, nebula, galaxies and the like are not a part of this forum. I tend to focus on “terrestrial” places or places that host such places. I suppose I would like to find out more about these places that we may one day inhabit or simply visit."

The NASA list of "silliest" science fiction films outlines some complete horseshit offerings but is sci-fi meant to be realistic? Fans of hard sci-fi might argue it is the core of that place where dreaming and science combine, but shouldn't the dreaming part allow an amount of creative freedom in the hopes of getting at some larger truth? Some would say there is a point where you've gone too far. But what if our current impossible dream later becomes plausible, possible or reality?
