ISS – Expedition 57 Mission patch.

December 8, 2018

Three days after its launch from Florida, the SpaceX Dragon cargo spacecraft was installed on the Earth-facing side of the International Space Station’s Harmony module at 10:36 a.m. EST.

SpaceX CRS-16: Dragon berthing

The 16th contracted commercial resupply mission from SpaceX delivers more than 5,600 pounds of research, crew supplies and hardware to the orbiting laboratory. Among the research it will bring to station, science investigations and technology demonstrations aboard Dragon include:

The Global Ecosystem Dynamics Investigation (GEDI) will provide high-quality laser ranging observations of the Earth’s forests and topography required to advance the understanding of important carbon and water cycling processes, biodiversity, and habitat. GEDI will be mounted on the Japanese Experiment Module’s Exposed Facility and provide the first high-resolution observations of forest vertical structure at a global scale. These observations will quantify the aboveground carbon stored in vegetation and changes that result from vegetation disturbance and recovery, the potential for forests to sequester carbon in the future, and habitat structure and its influence on habitat quality and biodiversity.

A small satellite deployment mechanism, called SlingShot, will be ride up in Dragon and then be installed in a Northrop Grumman Cygnus spacecraft prior to its departure from the space station. SlingShot can accommodate as many as 18 CubeSats of any format. After the Cygnus cargo ship departs from station, the spacecraft navigates to an altitude of 280 to 310 miles (an orbit higher than that of the space station) to deploy the satellites.

Robotic Refueling Mission-3 (RRM3) will demonstrate the first transfer and long-term storage of liquid methane, a cryogenic fluid, in microgravity. The ability to replenish and store cryogenic fluids, which can function as a fuel or coolant, will help enable long duration journeys to destinations, such as the Moon and Mars.

Growth of Large, Perfect Protein Crystals for Neutron Crystallography (Perfect Crystals) crystallizes an antioxidant protein found inside the human body to analyze its shape. This research may shed light on how the protein helps protect the human body from ionizing radiation and oxidants created as a byproduct of metabolism. For best results, analysis requires large crystals with minimal imperfections, which are more easily produced in the microgravity environment of the space station.

Dragon is scheduled to depart the station in January 2019 and return to Earth with more than 4,000 pounds of research, hardware and crew supplies.

Greetings, Orbiter.chArchive link

The Aral Sea was once the
fourth-largest lake in the world. Fed primarily by snowmelt and precipitation
flowing down from faraway mountains, it was a temperate oasis in an arid
region. But in the 1960s, the Soviet Union diverted two major rivers to
irrigate farmland, cutting off the inland sea from its source. As the Aral Sea
dried up, fisheries collapsed, as did the communities that depended on them.
The remaining water supply became increasingly salty and polluted with runoff
from agricultural plots. Loss of the Aral Sea’s water influenced regional
climate, making the winters even colder and the summers much hotter.

While seasonal rains still
bring water to the Aral Sea, the lake is roughly one-tenth of its original size.
These satellite images show how the Aral Sea and its surrounding landscape has
changed over the past few decades.
