This Perseid fireball was observed by the NASA All Sky Fireball Network in the skies over New Mexico on the morning of August 12.

Dr. Bill Cooke, of NASA’s Meteroid Environment Office — located at NASA’s Marshall Space Flight Center in Huntsville, Alabama — explains what the All-Sky Camera Network is and how it’s used to track meteors or fireballs.

Direct Current Switching Unit (DCSU) 4A Power On Reset (POR): Tuesday evening at 6:10 pm CDT DCSU-4A experienced a POR.  Power was lost to 3 downstream Direct Current-to-Direct Current Converter Units (DDCUs) plus the DDCU on the P4 Integrated Equipment Assembly (IEA). Service Module voltage and current stabilizers [CHT]s 23 and 24 also lost power …

Rhiannon Blaauw, of NASA’s Meteoroid Environment Office — located at NASA’s Marshall Space Flight Center in Huntsville, Alabama — shares some tips and strategies to best view a meteor shower.

The International Space Station experienced a temporary power loss Tuesday night while backup systems maintained power to critical systems. Power was restored quickly and there were no impacts to station operations and the six-member crew was always safe. Astronauts Kjell Lindgren and Kimiya Yui are training for the robotic capture next week of Japan’s fifth …

Human Research Program (HRP) Operations: Yui completed his Flight Day 15 (FD15) Biochemical Profile Urine collections.  Kelly completed his second of three Journals sessions and his third task observation video for Habitability. The Biochemical Profile experiment tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the …

The Perseids are ramping up! Here’s a Perseid meteor captured by the NASA All Sky Fireball Network on August 4th. The shower will peak the morning of August 13th. With a near-new Moon, we may get a good show that morning!

International Space Station Expedition 44 Commander Gennady Padalka and Flight Engineer Mikhail Kornienko of the Russian Federal Space Agency completed a spacewalk lasting 5 hours, 31 minutes at 3:51 p.m. EDT. The spacewalkers rigged new equipment on the Russian segment of the complex and conducted a detailed photographic inspection of the exterior of the outpost. This was the …

Hi, I'm Kelsi Singer, a postdoctoral researcher at the Southwest Research Institute, working on NASA's New Horizons mission and specializing in geology and geophysics. One of my areas of expertise is impact cratering. That subject may not seem related to Pluto's atmosphere or nitrogen at first, but let me tell you about research that …
