Read about James Cameron's March 2012 record breaking deep ocean dive in the Mariana Trench where he was unable to retrieve rock and animals samples as plannned, and what his mission may foretell about trying to return samples from Mars.
France 2 et Michel Drucker proposent « une nuit dans l’espace » ce soir à partir de 20h35. L’animateur vedette de France 2 y célèbrera les 50 ans de la conquête spatiale française et européenne au cours d’une émission exceptionnelle.
Serial entrepreneur Elon Musk says SpaceX is developing a plan for trips to Mars that will eventually cost just $500,000 per seat. Musk founded SpaceX 10 years ago and interplanetary travel has always been one of his goals for the company. Few details were provided about the Martian voyage, but Musk did say we can expect to hear more about the plan in less than a year.
The APEX could be useful for future international spaceflight missions. It could help to assemble spacecraft in Earth orbit for lunar or Mars exploration missions. Its technologies could also be used in Martian orbit to retrieve samples collected from the surface of the Red Planet by future missions.
NASA would rather that ESA contribute to developing its Orion Multi-Purpose Crew Vehicle (MPCV), but France will reject this option since it will not spur sufficiently innovation in Europe.
Two ambitious missions that NASA had hoped to launch to Mars, in 2016 and 2018, will be canceled.
"Dr. Tyson implored Congress to look beyond the near-term budget travails, noting that of each dollar in taxes sent to Washington, only half a cent is spent on NASA. He told the senators they should double NASA’s budget.
“The moment the culture wants to innovate, that penny on a dollar becomes an investment,” Dr. Tyson said, arguing that the nation had benefited greatly from the halo effects of the space program in the 1960s and 1970s and has been coasting since."
A proposal to only launch ultra thin and light inflatable mirrors (no power conversion, no energy storage, no lasers or masers to transmit the power etc...) and have them redirect sunlight to ground based solar farms at night. Efficiency is the ground based systems efficiency. Can be done at lower orbit 600 miles up with 12 or more satellites. Helps ground based solar get around the storage issue at night. Again best to do it to desert locations without clouds. Also away from places that want to do astronomy or have other impacts of turning the night into day. Just need to get astronomy into space and away from the light. Again get past a critical mass of space based power capability and infrastructure so that it is easy to make 500 MW of lasers for boosting skylon space planes to drive down costs to get to space.
In his first blog about NASA turning to commercial providers for launch vehicles, Richard Garriot explains why we spend money on human exploration of space. Space research is essential and humans in space are an essential part of it.
Pretty much everyone can rattle off the names of our solar system's eight (formerly nine) planets, but ask the average person to list some moons and you'll be lucky if they can tell you more than two or three.
Les préparatifs en vue du lancement le 30 avril de la capsule Dragon de la société américaine SpaceX vers la Station spatiale internationale (ISS), une première pour une firme privée, se poursuivent sans problème majeur, selon un responsable de la Nasa.
Pour ExoMars, les clignotants repassent au vert. En trouvant un terrain d’entente avec la Russie, l’Agence spatiale européenne sauve sa mission emblématique bien mal engagée après le retrait de la Nasa dans le projet.
SpaceX is working to uncover routine man/machine interface issues between astronauts and its Dragon spacecraft. It is also pressing Falcon 9 rocket engine tests to prevent costly delays in satellite launches that make up 60% of the company’s business.
NASA and SpaceX are now targeting an April 30 launch window for liftoff of the first unmanned Dragon cargo flight to the International Space Station.
