It seems like for every rocket launch that is successful, a few dozen are scrubbed! Why do rocket launches get cancelled so often? SpaceX scrubs rocket recovery launch http://www.bbc.com/news/science-environment-30696895 "US company SpaceX has postponed an experiment to bring part of its Falcon rocket down to a soft landing on a floating sea platform." SpaceX mission could herald new era of reusable rockets http://www.theguardian.com/science/2015/jan/05/spacex-mission-reusable-rockets-elon-musk "A test launch on Tuesday by the private space company SpaceX could be historic, not for where its rocket goes but for where it lands - and that it lands safely at all. All being well, the rocket will return to Earth on a giant floating platform in the Atlantic Ocean." Keeping An Eye On Launch Day Weather http://www.rocketstem.org/2014/01/14/keeping-eye-launch-day-weather/ "Before MAVEN can study the atmosphere of Mars, it had to not only overcome Earth's gravity but also make it through Earth's atmosphere. Central Florida's sometimes volatile weather can make launching rockets difficult. Weather is responsible for more than a third of launch delays and nearly half of the scrubs." Space Shuttle Weather Launch Commit Criteria and KSC End of Mission Weather Landing Criteria http://www.nasa.gov/centers/kennedy/news/releases/2003/release-20030128.html "The launch weather guidelines involving the Space Shuttle and expendable rockets are similar in many areas, but a distinction is made for the individual characteristics of each. The criteria are broadly conservative and assure avoidance of possibly adverse conditions." Why are rocket launches so sensitive to weather? http://space.stackexchange.com/questions/4967/why-are-rocket-launches-so-sensitive-to-weather "Two of the primary weather-related concerns that prevent rockets from launch during inclement weather are lightning and wind." Space Radiation Can Affect Rocket Launches http://www.nasa.gov/content/goddard/space-radiation-can-affect-rocket-launches/#.VKwX7IrF-TE "On Jan. 8, 2014, Orbital Sciences Corp. elected to scrub that day's launch attempt of an Antares rocket from NASA's Wallops Flight Facility, Wallops Island, Va., due to unusually high levels of space radiation - an example of the ways in which space weather can affect human technology." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!
