NASA - NASA and Microsoft Allow Earthlings to Become Martians
"PASADENA, Calif. -- NASA and Microsoft Corp. of Redmond, Wash., have collaborated to create a Web site where Internet users can have fun while advancing their knowledge of Mars.
Drawing on observations from NASA's Mars missions, the "Be a Martian" Web site will enable the public to participate as citizen scientists to improve Martian maps, take part in research tasks, and assist Mars science teams studying data about the Red Planet.
"We're at a point in history where everyone can be an explorer," said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington. "With so much data coming back from Mars missions that are accessible by all, exploring Mars has become a shared human endeavor. People worldwide can expand the specialized efforts of a few hundred Mars mission team members and make authentic contributions of their own."

NASA - NASA Researchers Make First Discovery of Life's Building Block in Comet
NASA scientists have discovered glycine, a fundamental building block of life, in samples of comet Wild 2 returned by NASA's Stardust spacecraft.
"Glycine is an amino acid used by living organisms to make proteins, and this is the first time an amino acid has been found in a comet," said Dr. Jamie Elsila of NASA's Goddard Space Flight Center in Greenbelt, Md. "Our discovery supports the theory that some of life's ingredients formed in space and were delivered to Earth long ago by meteorite and comet impacts."
Tähdet ja avaruus: Komeetasta löytyi aminohappoa
Nasan Stardust-luotaimen ottamasta komeettanäytteestä on löytynyt glysiini-aminohappoa. Tutkijoiden mukaan löytö viittaa elämän esiintymisen olevan avaruudessa yleisempää kuin ennen on luultu.
"Glysiini on aminohappo, jota eliöt käyttävät proteiinien valmistamiseen, ja tämä on ensimmäinen kerta kun aminohappo on löydetty komeetasta", hehkuttaa Jamie Elsila Nasan Goddardin avaruuslentokeskuksesta. "Löytömme vahvistaa teoriaa, että osa elämän tarvitsemista aineista syntyi avaruudessa ja putosi Maahan kauan sitten meteoriittien tai komeettojen törmäyksissä."
Sarychev Peak Eruption, Kuril Islands : Image of the Day - Earth Observatory - NASA
A fortuitous orbit of the International Space Station allowed the astronauts this striking view of Sarychev Volcano (Kuril Islands, northeast of Japan) in an early stage of eruption on June 12, 2009. Sarychev Peak is one of the most active volcanoes in the Kuril Island chain, and it is located on the northwestern end of Matua Island. Prior to June 12, the last explosive eruption occurred in 1989, with eruptions in 1986, 1976, 1954, and 1946 also producing lava flows. Ash from the multi-day eruption has been detected 2,407 kilometers east-southeast and 926 kilometers west-northwest of the volcano, and commercial airline flights are being diverted away from the region to minimize the danger of engine failures from ash intake.
NASA LCROSS Project Site
After its successful launch, LCROSS is now on its way to the moon!
At Launch +5 days, the spacecraft will perform a lunar swingby
to enter into an elongated Earth orbit to position LCROSS
for impact at the lunar south pole.
LCROSS lunar swingby video stream coverage
will begin @ about 5:20 a.m. PDT on Tuesday, June 23, 2009.
Please check http://www.nasa.gov/mission_pages/LCROSS/lunarswingby/
for updates during the early morning on Tuesday, June 23, 2009.

LCROSS Lunar Swingby Streaming Video (Launch +5 days)
LCROSS lunar swingby video stream coverage will begin approximately 5:10 a.m. PDT on Tuesday, June 23, 2009. First video data from the LCROSS spacecraft will come in at 5:20 a.m.
After its successful launch, LCROSS is now on its way to the moon. Approximately five days after launch, the spacecraft will perform a lunar swingby to enter into an elongated polar Earth orbit to position LCROSS for impact on the lunar south pole (see mission overview video). Shortly after periselene, the time of closest approach to the lunar surface, the LCROSS science payload will be switched on for the duration of one hour for calibration of its cameras and spectrometers.
