    Jupiterís moon Europa has the most water in the entire Solar System. If you took all the water on Earth, collected it into a big sphere, it would measure almost 1,400 kilometers across. Europaís water would measure nearly 1,800 kilometers.All that water exists in a layer around Europa, encased in a layer of ice. ... According to the plan, a spacecraft will launch in the 2020s, carrying 9 instruments to Europa. Most will be familiar cameras, mass spectrometers, and the like, to study the surface of Europa to a high level of resolution. Over the course of 45 flybys, the...

    Traveling to the Moon just got a whole lot cheaper. A NASA-funded study (PDF) has found that the cost of lunar missions could be reduced by a factor of 10 using a number of techniques Ė and it could also have implications for getting humans to Mars. The extensive NexGen Space study by the National Space Society (NSS) and the Space Frontier Foundation (SFF) said that partnerships with private companies could return humans to the Moon for $10 billion (£6.4 billion), rather than the previosuly estimated $100 billion (£64 billion) that had turned off potential suitors.

    MOSCOW (AFP) - Astronauts from Russia, Japan and the United States Thursday docked successfully with the International Space Station after a two-month delay, despite a minor hiccup. The Soyuz TMA 17M rocket -- carrying cosmonaut Oleg Kononenko, US astronaut Kjell Lindgren and Kimiya Yui of Japan -- blasted off from the Baikonur cosmodrome on schedule after a two-month delay caused by the failure of a Russian rocket during an unmanned resupply mission. The launch and the docking were successful even though one solar array -- a type of power supply that captures energy from the sun -- did not deploy...
  • Testing shows using microwaves to propel a craft into space might work

    07/23/2015 12:10:47 PM PDT · by Red Badger · 28 replies
    =============================================================================================== A team of researchers at Colorado based Escape Dynamics is reporting that initial tests indicate that it might really be possible to launch space-planes into space using microwaves sent from the ground, to allow for a single stage spacecraft. If the idea pans out, the cost savings for sending satellites (or perhaps humans) into orbit could be considerable. Today's rockets are all based on the same idea, a multi-stage rocket is used, each part filled with propellant that pushes the rocket into space as the propellant is burned. It is a really expensive way to go because the propellant...

During a 535-second test, operators ran the RS-25 through a series of power levels, including a period of firing at 109 percent of the engine's rated power. Data collected on performance of the engine at the various power levels will aid in adapting the former space shuttle engines to the new SLS vehicle mission requirements, including development of an all-new engine controller and software. Four RS-25 engines will use the...

    A "close pass" by orbiting junk has forced the International Space Station's crew to scramble into its attached Soyuz capsule. It is the fourth time in ISS's 15 years that a collision risk has prompted such precautions. Three astronauts briefly fled the International Space Station (ISS) on Thursday as a fragment of a former Soviet weather satellite flew by. They sheltered in a Soyuz spacecraft, which normally transports crew members to and from Earth. A space industry source quoted by the Russian news agency Interfax claimed that US space monitors had spotted the space junk "very late." That had left...

    The latest data downloaded from NASA's New Horizons spacecraft suggests that mountains of nitrogen ice thousands of feet high have evaporated into Pluto's atmosphere since the dwarf planet formed 4.5 billion years ago, and hundreds of tons of that gas escape into space each hour. New images of Pluto meanwhile show land forms that suggest heat is rising beneath the surface, with troughs of dark matter either collecting or bubbling up between flat segments of crust. Scientists discussed the findings Friday in their second major release of data collected when the $700 million New Horizons mission made a historic pass...

How large? Based on New Horizons imagery, its diameter is 2,370 kilometers (1,473 miles), plus or minus 20 kilometers (12.4 miles). That makes it almost 30 miles wider than Eris, the dwarf planet whose discovery led to Pluto's downfall as the "ninth planet" back in 2006. Eris' diameter has been measured to be 2,326 kilometers...

    WASHINGTON: Extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans in recent years, which may explain the so-called 'pause' in global warming observed during the past decade, according to a new NASA study. Researchers from NASA's Jet Propulsion Laboratory (JPL), California, found a specific layer of the Indian and Pacific oceans between 100 and 300 metres below the surface has been accumulating more heat than previously recognised. During the 20th century, as greenhouse gas concentrations increased and trapped more heat energy on Earth, global surface temperatures also increased. However, in the 21st...

    It wasnít the Martiansí fault their planet died. If they existed Ė once Ė Martians were likely microbes, living in a world much like our own, warmed by an atmosphere and crisscrossed by waterways. But Mars began to lose that atmosphere, perhaps because its gravity wasnít strong enough to hold onto it after an asteroid impact, or perhaps it was gradually blown away by solar winds. The cause is still mysterious, but the ending is clear: Marsís liquid water dried up or froze into ice caps, leaving life without its most precious resource. Any Martians would have been victims of...
  • National Space Society Opposes Senate Gutting of Commercial Crew Program

    National Space Society Opposes Senate Gutting of Commercial Crew Program [and investing in Russian economy] The National Space Society (NSS) strongly opposes the Senate Appropriations Committeeís $344 million (27%) cut of the 2015 Commercial Crew budget requested by the Administration. The Senate cuts were $100 million more than those recently passed by the House. NSS stands with NASA administrator Charles Bolden when he said ďBy gutting this program and turning our backs on U.S. industry, NASA will be forced to continue to rely on Russia to get its astronauts into space Ė and to continue to invest hundreds of millions...

    European scientists are celebrating after receiving a remarkable communication from space. The solar-powered Philae comet probe is sending signals back to earth after seven months of silence. The Philae spacecraft has been in touch with Earth from a speeding comet for the second time since waking up a few days ago, mission control said Monday, and scientists hope to improve communications with the lander by shifting the trajectory of its mother ship. Philae in November became the first spacecraft ever to settle on a comet when it touched down on icy 67P/Churyumov-Gerasimenko, but it managed to send data to Earth...

    Texas Sen. Ted Cruz supports NASA's human space exploration program as a national priority that deserves congressional support. USA Today†reports if NASA's program goes as planned, astronauts could travel to Mars by the 2030s. Cruz, a†Tea Party Republican, said developing a rocket and capsule that could cost tens of billions of dollars is "critical" to ensuring American's leadership in space. "It is imperative that America has the capability to get to the space station without the assistance of the Russians," Cruz said Tuesday while chairing a hearing before the Commerce, Science and Transportation Subcommittee on Science, Space and Competitiveness.†"The Commercial...

    Those of us in the media arenít necessarily well known for having the longest attention span. By our very nature, we may be captivated by a story one week and then suddenly find ourselves unable to recall its most basic details when a new, juicy headline comes along. This may be how the game is played in Washington, but itís frustrating, especially when you remember a moment of panic that everybody else seems to move on from. In 2006, that concern was over port security and was centered on President George W. Bush approving a deal with Dubai Ports World...

    SEATTLE, Feb. 22, 2005 -- Boeing [NYSE: BA] today said development of the 747 Large Cargo Freighter is proceeding according to plan and the modified freighters will be ready to support final assembly of the first Boeing 787 Dreamliners in 2007. "We have a top-notch team of engineers working to design what will be one of the most unique airplanes flying," said 787 Vice President of Manufacturing and Quality Scott Strode. "This kind of modification is an engineer's dream. It's an extremely challenging project, and it's essential to the success of the Dreamliner." Boeing announced last week the critical "swing...

    It seems like Mars has just about everything: auroras, water, and now... glass? In a paper published recently in Geology researchers announced that NASA's Mars Reconnaissance Orbiter (MRO) found deposits of glass in craters on the Martian surface. These are the first deposits ever found on Mars, and they could help us figure out if there was ever life on the red planet. On Mars, the glass was created when meteorites slammed into the Martian surface with enough force to melt some of the rocks, which then cooled quickly enough in the atmosphere, turning them into a type of glass...

    The first thing to notice is how rapidly Elon Musk's SpaceX is altering the market for government-sponsored rocket launches. Witness how frequently the words "to compete with SpaceX" appear in industry statements and press coverage. To compete with SpaceX, say multiple reports, the United Launch Alliance, the Pentagon's traditional supplier, is developing a new Vulcan rocket powered by a reusable engine designed by Jeff Bezos's Blue Origin. Because of SpaceX, says Aviation Week magazine, Japan's government has instructed Mitsubishi to cut in half the cost of the Japanese workhorse rocket, and China is planning a new family of kerosene-fueled Long...
  • Airbus Unveils Partially Reusable Rocket Design 'Adeline'

    But can it ever hope to compete with SpaceX? Like the Falcon 9, Adeline is only partially reusable -- but the way it's meant to work is quite creative. While most of the rocket's fuselage goes unrecovered after launch, the bottom portion of the rocket housing the main engine (most expensive part and arguably the most important) is designed to safely return back home. The design calls for the first stage of the rocket to come equipped with wings and propellers, allowing it to travel back to Earth like a small plane and land gently on a runway. The key...

    In July, New Horizons crosses the next great frontier in our solar system. Mankind is about to visit one of the strangest places in our solar system. Out beyond Neptune, the Kuiper belt is home to hordes of cold, lumpy worlds -- some of which are large enough to have their own moons, but none of which we've seen up-close before. That's going to change this summer, when NASA's New Horizons spacecraft flies by "the king of the Kuiper belt": Pluto. It's no longer considered a planet, but Pluto is still an important member of our solar system, and one...
