The SpaceX Falcon 9 rocket is now poised at the launch pad and set to open a completely new era in spaceflight. Hopes are sky high that Saturday mornings Falcon 9 launch represents the dawn of the commercial era in spaceflight akin to the startup of the commercial airline industry early in the 20th Century [...] [ Čítaj celý článok ]

The old saying of the universe being stranger than we can imagine definitely applies to a newfound exoplanet orbiting a star about 1,500 light years from Earth. Researchers using the Kepler space observatory have detected what appears to be a planet about the size of Mercury literally turning to dust. A long tail of debris [...] [ Čítaj celý článok ]

Saturday morning’s launch window for SpaceX’s historic test flight to the International Space Station lasts just one second. Company President Gwynne Shotwell predicted they have “better than a 50-50 shot on whether we lift off tomorrow,” she said at a press conference today, adding, “If we lift off, we’ll get to orbit.” Shotwell and NASA [...] [ Čítaj celý článok ]

With less than a day left before SpaceX’s historic launch of the first commercial vehicle to the ISS, slated for 4:55 am EDT on Saturday, May 19, here’s a video of what will happen once the Falcon lifts off. (Part of me really wishes that they’ll be pumping out some dramatic music when it launches!) [...] [ Čítaj celý článok ]

Researchers at Stanford University are working on solutions to the inherent difficulties of hypersonic flight — speeds of over Mach 5, or 3,000 mph (4828 km/h) — and they’ve created one amazing computer model illustrating the dynamics of air temperature variations created at those intense speeds.

This great video created from images taken by the Solar and Heliospheric Observatory (SOHO) on May 13 and 14 show Jupiter as it comes close to the Sun (from our vantage point) in a solar conjunction. But what it really looks like is the old “Space Invaders” video game, with Jupiter marching across the screen. [...] [ Čítaj celý článok ]

Just look at the kind of stunning images that are buried in the archives from the Hubble Space Telescope! Here, Hubble turned its powerful wide field Advanced Camera for Surveys towards this spiral galaxy and took this close-up of its northern half. The entire galaxy, called NGC 891, stretches across 100,000 light-years and we see [...] [ Čítaj celý článok ]

COSMOS. Seth MacFarlane. Neil deGrasse Tyson. Need we say more?

In less than 48 hours, SpaceX is primed to make history and launch the first ever commercial rocket and spacecraft to the International Space Station (ISS) early Saturday morning on May 19. Following today’s Launch Readiness Review (LRR), SpaceX was just given the official “GO” from NASA to proceed with the blastoff of the Falcon [...] [ Čítaj celý článok ]
