20/10/2014 - The longest-lived robot ever sent to Mars came through its latest challenge in good health, reporting home on schedule after sheltering behind Mars from possible comet dust. NASA's Mars Odyssey was out of communications with Earth, as planned, while conducting observations of comet C/2013 A1 Siding Spring on Sunday, Oct. 19, as the comet flew near Mars. The comet sped within about 88,000 miles (139,500 kilometers) of Mars, equivalent to about one-third of the distance between Earth and Earth's moo ... (source: spacedaily.com - more...)

17/10/2014 - A top secret US robot space plane landed back on Earth on Friday after a 22-month orbit, officials said, although the craft's mission remains shrouded in mystery. The unmanned X-37B, which looks like a miniature space shuttle, glided into the Vandenberg Air Force Base in California after having launched on December 11, 2012, on a mission that military officers say is still strictly secret. "I'm extremely proud of our team for coming together to execute this third safe and successful landing, sai ... (source: spacedaily.com - more...)

17/10/2014 - Astronomers using the National Science Foundation's Green Bank Telescope (GBT) in West Virginia, along with data from other large radio telescopes, have discovered that our nearest galactic neighbors, the dwarf spheroidal galaxies, are devoid of star-forming gas, and that our Milky Way Galaxy is to blame. These new radio observations, which are the highest sensitivity of their kind ever undertaken, reveal that within a well-defined boundary around our Galaxy, dwarf galaxies are completely devoid o ...

16/10/2014 - An Ariane 5 ECA returned to action on Thursday evening, lofting two satellites into space. ArSat-1 and Intelsat DLA-1 (Intelsat 30) rode uphill on the Arianespace workhorse out of the European Spaceport in Kourou, French Guiana. Lift off came midway through a 51 minute launch window that opened at 21:44 GMT, following a weather and satellite related hold. (source: nasaspaceflight.com - more...)

16/10/2014 - NASA's MAVEN spacecraft has provided scientists their first look at a storm of energetic solar particles at Mars and produced unprecedented ultraviolet images of the tenuous oxygen, hydrogen and carbon coronas surrounding the Red Planet, said University of Colorado Boulder Professor Bruce Jakosky, the mission's principal investigator. In addition, the new observations allowed scientists to make a comprehensive map of highly variable ozone in the Martian atmosphere underlying the coronas, he said. ...

14/10/2014 - Russia will take the Moon exploration as a core of its space program for the next decade, Federal Space Agency Roscosmos said Friday. "This year Roscosmos has prepared a long-term program of deep space exploration, with exploration of the Moon as the core," the agency's official Yuri Makarov said. According to the Roscosmos official website, the new program is also aimed at exploring other planets in the Solar System. The program envisages building infrastructure of the permanent lunar ...

11/10/2014 - Mars One is a nonprofit that has plans to put humans on Mars by 2025, but doctoral students at MIT believe the current plans could put the colonists at risk of starving to death. The students used public information to simulate the mission and found that under the current plan, which calls for growing crops inside, it will be difficult to grow enough food for the colony while maintaining safe oxygen levels. "Our habitation simulations revealed that crop growth, if large enough to provide ... (source: spacedaily.com - more...)

11/10/2014 - European satellite launch company Arianespace on Wednesday said a shortcoming in the design stages was behind an anomaly that occurred during August's Soyuz mission to carry two satellites in the Galileo constellation from Europe's Spaceport in French Guiana. "The root cause of the anomaly on flight VS09 is a shortcoming in the system thermal analysis during stage design, and not an operator error during stage assembly," an independent inquiry commission said. "The system thermal analyses ha ... (source: spacedaily.com - more...)

10/10/2014 - A team of scientists including a University of Colorado Boulder professor used NASA's Hubble Space Telescope to make the most detailed global map yet of the glow from a giant, oddball planet orbiting another star, an object twice as massive as Jupiter and hot enough to melt steel. The Hubble observations show that the planet, called WASP-43b, is no place to call home. It's a world of extremes, where winds howl at the speed of sound from a 3,000-degree-Fahrenheit dayside to a pitch-black nightside ... (source: spacedaily.com - more...)

09/10/2014 - Boeing Co. and SpaceX, selected by NASA last month to carry astronauts to the International Space Station, can resume development of their human-rated spacecraft after officials ordered a work stoppage prompted by a protest by Sierra Nevada Corp., the company left out of the contracts, NASA said Thursday.

08/10/2014 - Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s. The upward trend in the Antarctic, however, is only about a third of the magnitude of the rapid loss of sea ice in the Arctic Ocean. The new Antarctic sea ice record reflects the diversity and complexity of Earth's environments, said NASA researchers. Claire Parkinson, a senior scient ... (source: spacedaily.com - more...)
