Astronaut Barry Wilmore on the First of Three Spacewalks

NASA astronaut Barry Wilmore works outside the International Space Station on the first of three spacewalks preparing the station for future arrivals by U.S. commercial crew spacecraft, Saturday, Feb. 21, 2015. Fellow spacewalker Terry Virts, seen reflected in the visor, took this photograph and shared it on social media.

The spacewalks are designed to lay cables along the forward end of the U.S. segment to bring power and communication to two International Docking Adapters slated to arrive later this year. The new docking ports will welcome U.S. commercial spacecraft launching from Florida beginning in 2017, permitting the standard station crew size to grow from six to seven and potentially double the amount of crew time devoted to research.

The second and third spacewalks are planned for Wednesday, Feb. 25 and Sunday, March 1, with Wilmore and Virts participating in all three.

John Glenn During the Mercury-Atlas 6 Spaceflight

On Feb. 20, 1962, astronaut John H. Glenn, Jr., became the first American to orbit Earth. Launched from Cape Canaveral Launch Complex 14, Glenn’s Mercury-Atlas 6 “Friendship 7” spacecraft completed a successful three-orbit mission, reaching a maximum altitude (apogee) of approximately 162 statute miles and an orbital velocity of approximately 17,500 miles per hour. The flight lasted a total of 4 hours, 55 minutes, and 23 seconds before the spacecraft splashed down in the ocean. This photograph of John Glenn during the Mercury-Atlas 6 spaceflight was taken by a camera onboard the spacecraft.

Magnetospheric Multiscale Observatories Processed for Launch

NASA’s Magnetospheric Multiscale (MMS) observatories are processed for launch in a clean room at the Astrotech Space Operations facility in Titusville, Florida. MMS is an unprecedented NASA mission to study the mystery of how magnetic fields around Earth connect and disconnect, explosively releasing energy via a process known as magnetic reconnection. MMS consists of four identical spacecraft that work together to provide the first three-dimensional view of this fundamental process, which occurs throughout the universe.

The mission observes reconnection directly in Earth’s protective magnetic space environment, the magnetosphere. By studying reconnection in this local, natural laboratory, MMS helps us understand reconnection elsewhere as well, such as in the atmosphere of the sun and other stars, in the vicinity of black holes and neutron stars, and at the boundary between our solar system’s heliosphere and interstellar space.

MMS is a NASA mission led by the Goddard Space Flight Center. The instrument payload science team consists of researchers from a number of institutions and is led by the Southwest Research Institute. Launch of the four identical observatories aboard a United Launch Alliance Atlas V rocket from Space Launch Complex 41 on Cape Canaveral Air Force Station is managed by Kennedy Space Center’s Launch Services Program. Liftoff is currently targeted for 10:44 p.m. EDT on March 12.

Snow-Covered Northeastern United States

Yet another potent winter storm battered the northeastern United States on Feb. 14-15, 2015. The nor’easter brought 12 to 20 inches (30 to 50 centimeters) of snow across much of eastern New England, along with tropical storm force winds over 60 miles (100 kilometers) per hour. The latest snowfall pushed Boston to its highest monthly total on record—58 inches and counting—and its third highest yearly snow total.

This image shows the snow-covered northeastern states as observed on Feb. 16, 2015, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Cloud streets over the Atlantic Ocean in both images hint at the potent winds blowing across the East Coast from the Canadian interior. Following the blizzard, temperatures dropped as low as -30 degrees Fahrenheit (-34° Celsius) in parts of New England.

What the images do not show is snow depth. With the latest storm, nearly 8 feet (2.4 meters) of snow has fallen on the city of Boston in just three weeks. With temperatures persistently below freezing, very little snow has melted. According to National Climatic Data Center statistics the snow depth just south of Boston was roughly 42 inches (107 centimeters). Totals were above 30 inches (76 centimeters) in many locations in Maine, New Hampshire, and Massachusetts.

As of Feb. 17, the snow depth near Boston was greater than in all but two reported locations in Alaska. It was significantly higher than the notoriously snowy states of Michigan, Wisconsin, and Minnesota. Only Buffalo, New York, had a higher snow pack.

On Feb. 16-17, more snow and ice fell across the eastern United States from northern Mississippi all the way to Maine.

Dawn Approaches: Two Faces of Ceres

These two views of Ceres were acquired by NASA’s Dawn spacecraft on Feb. 12, 2015, from a distance of about 52,000 miles (83,000 kilometers) as the dwarf planet rotated. The images have been magnified from their original size.

The Dawn spacecraft is due to arrive at Ceres on March 6, 2015.

Dawn’s mission to Vesta and Ceres is managed by the Jet Propulsion Laboratory for NASA’s Science Mission Directorate in Washington. Dawn is a project of the directorate’s Discovery Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama. UCLA is responsible for overall Dawn mission science. Orbital ATK, Inc., of Dulles, Virginia, designed and built the spacecraft. JPL is managed for NASA by the California Institute of Technology in Pasadena. The framing cameras were provided by the Max Planck Institute for Solar System Research, Göttingen, Germany, with significant contributions by the German Aerospace Center (DLR) Institute of Planetary Research, Berlin, and in coordination with the Institute of Computer and Communication Network Engineering, Braunschweig. The visible and infrared mapping spectrometer was provided by the Italian Space Agency and the Italian National Institute for Astrophysics, built by Selex ES, and is managed and operated by the Italian Institute for Space Astrophysics and Planetology, Rome. The gamma ray and neutron detector was built by Los Alamos National Laboratory, New Mexico, and is operated by the Planetary Science Institute, Tucson, Arizona.

Growing Deltas in Atchafalaya Bay

The delta plain of the Mississippi River is disappearing. The lobe-shaped arc of coastal land from the Chandeleur Islands in eastern Louisiana to the Sabine River loses a football field’s worth of land every hour. Put another way, the delta has shrunk by nearly 5,000 square kilometers (2,000 square miles) over the past 80 years. That’s as if most of Delaware had sunk into the sea.

Though land losses are widely distributed across the 300 kilometer (200 mile) wide coastal plain of Louisiana, Atchafalaya Bay stands as a notable exception. In a swampy area south of Morgan City, new land is forming at the mouths of the Wax Lake Outlet and the Atchafalaya River. Wax Lake Outlet is an artificial channel that diverts some of the river’s flow into the bay about 16 kilometers (10 miles) west of where the main river empties.

Both deltas are being built by sediment carried by the Atchafalaya River. The Atchafalaya is a distributary of the Mississippi River, connecting to the “Big Muddy” in south central Louisiana near Simmesport. Studies of the geologic history of the meandering Mississippi have shown that—if left to nature—most of the river’s water would eventually flow down the Atchafalaya. But the Old River Control Structure, built in the 1960s by the U.S. Army Corps of Engineers, ensures that only 30 percent of the Mississippi flows into the Atchafalaya River, while the rest of the keeps moving toward Baton Rouge and New Orleans.
