Space Station’s Expandable Habitat

The Bigelow Expandable Activity Module (BEAM) is seen attached to the Tranquility module of the International Space Station. BEAM is an is an experimental expandable habitat. Expandable habitats, occasionally described as inflatable habitats, greatly decrease the amount of transport volume for future space missions. via NASA http://ift.tt/2dKqV2g

Testing the James Webb Space Telescope Pathfinder

In this photograph taken on Sept. 1, 2016, the James Webb Space Telescope Pathfinder structure has been configured for the Thermal Pathfinder Test at NASA Johnson Space Center’s giant thermal vacuum chamber, called Chamber A. The Pathfinder is a test version of the structure that supports the telescope. via NASA http://ift.tt/2dufZGQ

Water Swirls, Gulf of St. Lawrence

Orbiting above eastern North America, a crew member on the International Space Station photographed a dense pattern of eddies in the Gulf of St. Lawrence. Caught briefly in the Sun’s “glint point,” reflections off the water surface show an interlinked mass of swirls and eddies in the shallow water north of Prince Edward Island. via … Continue reading

Tectonically Active Planet Mercury

New NASA-funded research suggests that Mercury is contracting even today, joining Earth as a tectonically active planet. Images obtained by NASA’s MESSENGER spacecraft reveal previously undetected small fault scarps— cliff-like landforms that resemble stair steps. via NASA http://ift.tt/2d3OfXI

Practicing Orion Spacecraft Recovery After Splashdown

A group of U.S. Navy divers, Air Force pararescuemen and Coast Guard rescue swimmers practice Orion underway recovery techniques in the Neutral Buoyancy Laboratory at NASA’s Johnson Space Center to prepare for the first test flight of an uncrewed Orion spacecraft with the agency’s Space Launch System rocket during Exploration Mission (EM-1). via NASA http://ift.tt/2cZqSuR

One Billion Base Pairs Sequenced on the Space Station

NASA astronaut Kate Rubins checks a sample for air bubbles prior to loading it in the biomolecule sequencer. When Rubins’ expedition began, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbiting laboratory. … Continue reading

Space Station Flight Over the Southern Tip of Italy

The southern tip of Italy is visible in this image taken by the Expedition 49 crew aboard the International Space Station on Sept. 17, 2016. The brightly lit city of Naples can be seen in the bottom section of the image. A Russian Soyuz spacecraft can be seen in the foreground. via NASA http://ift.tt/2cAAbBy
