New Simulation Shows How Seeds of First Stars Formed: Scientific American
"The results help illuminate the "cosmic dark ages" during the first billion years after the big bang that kicked off the universe some 13.7 billion years ago.
Variations in the cosmic microwave background radiation tell researchers that matter resulting from the big bang was unevenly distributed. Stars and galaxies formed in areas where gas was concentrated. Sounds simple enough, but the huge distances involved have made simulations challenging.
In the new study, researchers from Nagoya University in Aichi, Japan, the National Astronomical Observatory of Japan in Tokyo and Harvard University computed the temperature and density of gas across thousands of light-years (much greater than the average distance between stars) at a resolution of about 50,000 miles (80,500 kilometers), 10 times smaller than the radius of the sun."

Rocket Man? Obama Tries to Hitch a Ride on Space Politics - Examiner.com
"Obama, who previously has called for drastic reductions in space, now apparently has seen the rocket light. After being introduced by astronaut Senator Bill Nelson, D-Fl, Obama invoked the names of Nelson and venerable multi-mission flyer Sen. John Glenn as his future space advisors.


Glenn, the first American to orbit the Earth, also flew in the Space Shuttle at age 77. Here's a comparison of the two vehicles and missions. In January 1986, Nelson spent six days orbiting Earth as a payload specialist aboard the space shuttle Columbia on mission STS 61-C."

"Famed US astronaut and politician John Glenn has said that that NASA's planned return to the Moon will be of no use to a future manned Mars mission.
"It seems to me the Moon is questionable as a way station," the former space ace and Senator told congressmen on Wednesday.
"If that's what we're doing - which I don't believe it is - but if that's what we're thinking about doing, that is enormously expensive," he added.
The House Science and Technology Committee were debating NASA's first 50 years and the future challenges faced by the space agency."

ファーストスター誕生:最先端のシミュレーションが示す初期宇宙での星形成
国立天文台
従来の数値実験では、ガスの化学反応や電磁波との相互作用は近似や経験則によって簡略化されていました。
そのような近似を行わず、物質の物理・化学過程を逐一計算するという手法をとりました。そして、仮想的な初期宇宙に広がる薄いガスが、重力によって集まり、原始星になるまで、約25桁にもわたる密度の変化を計算した
http://www.nao.ac.jp/

"名古屋大学国立天文台ハーバード大学の3人の研究者は、並列コンピューターを用いて、宇宙で最初の天体が生まれる様子を詳細に理論計算しました。
そして宇宙最初の天体は、質量が太陽の100分の1ほどの原始星 - 誕生初期の星であることを明らかにしました。
本研究で行った理論計算では、非常に高精度で得られている宇宙初期のわずかな密度揺らぎのデータ以外は、 観測的・経験的パラメータを用いていません。このような第一原理的理論計算として、宇宙で最初の天体が形成するまでのシミュレーションに世界で初めて成功しました。
研究成果は米科学誌サイエンス8月1日号に掲載されています"

New Simulation Shows How Seeds of First Stars Formed: Scientific American
"The results help illuminate the "cosmic dark ages" during the first billion years after the big bang that kicked off the universe some 13.7 billion years ago.
Variations in the cosmic microwave background radiation tell researchers that matter resulting from the big bang was unevenly distributed. Stars and galaxies formed in areas where gas was concentrated. Sounds simple enough, but the huge distances involved have made simulations challenging.
In the new study, researchers from Nagoya University in Aichi, Japan, the National Astronomical Observatory of Japan in Tokyo and Harvard University computed the temperature and density of gas across thousands of light-years (much greater than the average distance between stars) at a resolution of about 50,000 miles (80,500 kilometers), 10 times smaller than the radius of the sun."

"Nasa hopes the Falcon 9 can help fill the mission gap that will exist while it develops a successor to the shuttle.
That successor - known as Ares/Orion - is not expected to be flying before 2015, leaving a five-year break from shuttle retirement in 2010 during which the Americans would be reliant on international partners for all their ISS transportation needs. "

Rocket Man? Obama Tries to Hitch a Ride on Space Politics - Examiner.com
"Obama, who previously has called for drastic reductions in space, now apparently has seen the rocket light. After being introduced by astronaut Senator Bill Nelson, D-Fl, Obama invoked the names of Nelson and venerable multi-mission flyer Sen. John Glenn as his future space advisors.


Glenn, the first American to orbit the Earth, also flew in the Space Shuttle at age 77. Here's a comparison of the two vehicles and missions. In January 1986, Nelson spent six days orbiting Earth as a payload specialist aboard the space shuttle Columbia on mission STS 61-C."

John Glenn blasts Moonbase-to-Mars NASA roadmap | The Register
First then oldest in Earth orbit says start from there
"Famed US astronaut and politician John Glenn has said that that NASA's planned return to the Moon will be of no use to a future manned Mars mission.
"It seems to me the Moon is questionable as a way station," the former space ace and Senator told congressmen on Wednesday.
"If that's what we're doing - which I don't believe it is - but if that's what we're thinking about doing, that is enormously expensive," he added.
The House Science and Technology Committee were debating NASA's first 50 years and the future challenges faced by the space agency."

ファーストスター誕生:最先端のシミュレーションが示す初期宇宙での星形成
国立天文台
従来の数値実験では、ガスの化学反応や電磁波との相互作用は近似や経験則によって簡略化されていました。
そのような近似を行わず、物質の物理・化学過程を逐一計算するという手法をとりました。そして、仮想的な初期宇宙に広がる薄いガスが、重力によって集まり、原始星になるまで、約25桁にもわたる密度の変化を計算した
http://www.nao.ac.jp/

"名古屋大学国立天文台ハーバード大学の3人の研究者は、並列コンピューターを用いて、宇宙で最初の天体が生まれる様子を詳細に理論計算しました。
そして宇宙最初の天体は、質量が太陽の100分の1ほどの原始星 - 誕生初期の星であることを明らかにしました。
本研究で行った理論計算では、非常に高精度で得られている宇宙初期のわずかな密度揺らぎのデータ以外は、 観測的・経験的パラメータを用いていません。このような第一原理的理論計算として、宇宙で最初の天体が形成するまでのシミュレーションに世界で初めて成功しました。
研究成果は米科学誌サイエンス8月1日号に掲載されています"

New Simulation Shows How Seeds of First Stars Formed: Scientific American
"The results help illuminate the "cosmic dark ages" during the first billion years after the big bang that kicked off the universe some 13.7 billion years ago.
Variations in the cosmic microwave background radiation tell researchers that matter resulting from the big bang was unevenly distributed. Stars and galaxies formed in areas where gas was concentrated. Sounds simple enough, but the huge distances involved have made simulations challenging.
In the new study, researchers from Nagoya University in Aichi, Japan, the National Astronomical Observatory of Japan in Tokyo and Harvard University computed the temperature and density of gas across thousands of light-years (much greater than the average distance between stars) at a resolution of about 50,000 miles (80,500 kilometers), 10 times smaller than the radius of the sun."

SpaceX suffers third rocket launch failure | CNET News.com
"The failure occurred about two minutes after the launch of the two-stage Falcon 1 rocket, which was manufactured by Space Exploration Technologies, also known as SpaceX. A failure prevented the two stages from separating after the launch from a central Pacific atoll, SpaceX CEO Elon Musk said in a company blog. The rocket was carrying three satellites for NASA and the Department of Defense."
