Saturn V F-1 engine revived for tests

Saturn V engineNASA recalls an actual 1960s F-1 engine – of which clusters of five once launched the mighty Saturn V rockets during the Apollo lunar program – from the Smithsonian for refurbishment and, for the first time in over four decades, re-firing on a test stand at Marshall Space Flight Center in Alabama. NASA engineers examine the properties of the F-1 engine – whose performance still outrates the engines used during the Space Shuttle program – to learn how to improve the J-2X engines planned for use in the first stage of the SLS (Space Launch System) booster that will launch Orion vehicles.

A 90% chance of iron rain

Luhman 16bA team of scientists publishes a report in the journal Nature revealing that, using Doppler observations, they have achieved a very basic map of the “weather” patterns on the dim brown dwarf star Luhman 16B, discovered in 2013 at a distance of only 6.5 light years from Earth’s solar system. The observations reveal that the high temperature is likely to be 2,000 degrees Fahrenheit, with a very good chance of violent storms raining molten iron onto Luhman 16B’s surface in the forecast.
