Volcanic Sunset Alert
VOLCANIC SUNSETS: The Russian volcano that erupted directly beneath the International Space Station on June 12th is now causing beautiful lavender sunsets across parts of the northern USA and Europe. A plume of ash and sulfur dioxide from the Sarychev Peak eruption is circulating through the stratosphere, and when parts of the plume pass over an area at sunset, the sky fills with delicate white ripples, sometimes-colorful streamers, and a telltale hue of purple. Check today's edition for observing tips and a photo gallery.

Are We Alone for 06/29/09 - Humans in Space... ace... ace
Are We Alone - Humans in Space... ace... ace
ENCORE When the economy’s down, will humans still be going up – into space, that is? We investigate the future of human spaceflight at the International Astronautical Congress in Glasgow, Scotland and find out whether sending Homo sapiens to the Moon and Mars is still a good idea. Also, the chief of Virgin Galactic is happy to send you into space on a private flight – but it may max out your credit card.
Plus, an Apollo astronaut’s view from orbit… dining with South Korea’s first astronaut… and one of Britain’s great science fiction authors on how space science fuels the imagination.
Guests:
- Rusty Schweickart – Former NASA astronaut and Chairman of the Board of the B612 Foundation
- John Mankins – 25-year NASA veteran who managed the Agency’s exploration technology activities
- Sanjoy Som – Planetary scientist at the University of Washington, Seattle
- Will Whitehorn – President of Virgin Galactic

Volcanic Eruption Photographed from Space
VOLCANIC VISTAS: On June 12th, astronauts onboard the International Space Station watched in amazement as Russia's Sarychev Peak volcano erupted directly beneath their spacecraft. The rare photo they took is a must-see. An enormous sulfur dioxide plume from the eruption is now circumnavigating the globe at northern latitudes, producing spectacular sunsets for international air travelers. Today's edition of http://spaceweather.com features 3D photos of the eruption from space, satellite movies of the sulfur dioxide plume, and a Mars-like view of the volcanic cloud over the Canadian Arctic.

Live Video of Lunar Flyby
LUNAR FLYBY: Tomorrow morning, NASA's LCROSS (Lunar CRater Observation and Sensing Satellite) spacecraft will fly by the Moon and send pictures back to Earth from only 9000 km above the lunar surface. The purpose of the maneuver is to put LCROSS in an elongated Earth orbit and position it for impact at the lunar south pole later this year. Live video streaming of the flyby begins at approximately 5:20 AM PDT on Tuesday, June 23, 2009. Visit http://spaceweather.com for links and updates.
NEW SUNSPOTS: Since 2007, it has been unusual to see even a single spot on the sun. Today there are two. A pair of new-cycle sunspots is emerging in the sun's southern hemisphere. This is a good opportunity for readers with solar telescopes to witness sunspot genesis in action.

Electric-blue Clouds Sweep Across Europe
NIGHT-SHINING CLOUDS: On June 16th, a remarkably intense display of electric-blue noctilucent clouds (NLCs) swept across Europe. Sightings were made in Belgium, Denmark, the Netherlands, France, Germany, Poland and the British Isles. These mysterious clouds are known to flourish during years of solar minimum--and 2009 is such a year. This means more NLCs may be in the offing, not only over Europe but also North America and elsewhere. Check http://spaceweather.com for images, movies, and observing tips.
THE MYSTERY OF THE MISSING SUNSPOTS: The sun is in the pits of the deepest solar minimum in nearly a century. Where have all the sunspots gone? Scientists studying a jet stream deep inside the sun may have found the answer. Find the full story at http://spaceweather.com.

Running Out of This World
With NASA poised to launch the world's most famous treadmill (COLBERT) to the International Space Station, an astronaut describes what it's like to run in space where sweat floats and there is no gravity to hold your feet to the ground.

Japanese Spacecraft Set to Hit the Moon
http://spaceweather.com
IMPACT ALERT: Japan's Kaguya will crash into the Moon on Wednesday, June 10th, around 1830 UT. The timing favors observers in Asia and Australia, who might be able to see a flash of light or a plume of debris rising from the Moon's southeastern limb. The spacecraft masses 2,600 kg and it will slam into the lunar surface at 6,000 km/hr. No one knows, however, how bright the flash might be or whether it will be visible even through large telescopes. Images of the crash, if any are captured, will be posted on http://spaceweather.com .
Return of the Mars Hoax
There's an email going around claiming that Mars will look as big as a full Moon on August 27th. Could this possibly be true? Find out in today's story from Science@NASA:

Are We Alone - Bodies in Motion
Feel the need for speed? Well, you’ll need an extra helping of speed if you plan to leave the Earth and explore other parts of the solar system.

Arietid Meteor Shower this Weekend
DAYTIME METEORS: The annual Arietid meteor shower peaks on Sunday, June 7th. The Arietids are unusual because they are daytime meteors; they stream out of a point in the sky not far from the sun. The best time to look is just before dawn on Sunday morning when it may be possible to spot a small number of Arietids skimming the top of Earth's atmosphere. Such "Earthgrazing" meteors tend to be long, colorful, and very pretty. After daybreak, when the meteors are no longer visible to the human eye, you can listen to radar echoes from the Arietids by tuning in to our online meteor radar: http://spaceweatherradio.com .
"The Arietids are the strongest daylight shower of the year," notes Bob Lunsford of the American Meteor Society. "If you could see them through the sun's glare, you would count as many as 60 per hour. Also, don't forget that the daytime Zeta Perseids peak only two days later and are considered the second strongest daylight shower. In all my years of viewing I have never seen a Zeta Perseid, but I have seen a few Arietids. They have all been Earthgrazers and very impressive meteors."

Fake Astronaut Gets Hit by Artificial Solar Flare
Researchers are about to subject a fake astronaut complete with blood cells and simulated human tissue to an artificial solar flare. How the unlucky volunteer emerges from the radiation storm will reveal for the first time how much of a threat severe solar flares pose to astronauts en route to the Moon and Mars.
