The Neutron star Interior Composition Explorer (NICER) is a NASA Explorers program Mission of Opportunity dedicated to the study of the extraordinary gravitational, electromagnetic, and nuclear physics environments embodied by neutron stars, exploring the exotic states of matter where density and pressure are higher than in atomic nuclei. NICER will enable rotation-resolved spectroscopy of the thermal and non-thermal emissions of neutron stars in the soft (0.2–12 keV) X-ray band with unprecedented sensitivity, probing interior structure, the origins of dynamic phenomena, and the mechanisms that underlie the most powerful cosmic particle accelerators known. NICER will achieve these goals by deploying, following launch, an X-ray timing and spectroscopy instrument as an attached payload aboard the International Space Station (ISS).

NASA astronaut Jessica Meir, Oleg Skripochka of the Russian space agency Roscosmos, and Hazzaa Ali Almansoori from the United Arab Emirates (UAE) launched safely for their mission aboard the International Space Station on the Soyuz MS-15 spacecraft at 9:57 a.m. EDT. [September 25, 2019]

The crew began their six-hour trip to the orbital laboratory during which they will orbit Earth four times.

Wherever there are humans, there are microbes, too. Bacteria and fungi live all around us, in our homes, offices, industrial areas, the outdoors – even in space. People literally could not live without these tiny organisms, many of which are beneficial.

The trick is limiting the number of potentially harmful ones, particularly in a contained environment such as a spacecraft. So from the launch of the very first module of the International Space Station, NASA has monitored its microbial community.

Because the station is an enclosed system, the only way that microbes get there is hitching a ride on the contents of resupply spacecraft from Earth and on arriving astronauts. The NASA Johnson Space Center Microbiology Laboratory puts a lot of effort into knowing which microbes ride along.

The Soyuz launcher was introduced in 1966, deriving from the Vostok launcher, which in turn was based on the 8K74 or R-7a intercontinental ballistic missile. It was initially a three-stage rocket with a Block I upper stage. Later a Molniya variant was produced by adding a fourth stage, allowing it to reach the highly elliptical molniya orbit. A later variant was the Soyuz-U. While the exact model and variant designations were kept secret from the west, the Soyuz launcher was referred to by either the United States Department of Defense designation of SL-4, or the Sheldon designation of A-2 (developed by Charles S. Sheldon, an analyst with the Library of Congress). Both systems for naming Soviet rockets stopped being used as more accurate information became available.

The production of Soyuz launchers reached a peak of 60 per year in the early 1980s. It has become the world’s most used space launcher, flying over 1700 times, far more than any other rocket. Despite its age and perhaps thanks to its simplicity, this rocket family has been notable for its low cost and high reliability.
