ULA's Atlas V for Boeing's Orbital Flight Test

The Atlas V rocket that will launch Boeing’s CST-100 Starliner spacecraft on the company’s uncrewed Orbital Flight Test for NASA’s Commercial Crew Program is coming together inside a United Launch Alliance facility in Decatur, Alabama. The flight test is intended to prove the design of the integrated space system prior to the Crew Flight Test. These events are part of NASA’s required certification process as the company works to regularly fly astronauts to and from the International Space Station. Boeing's Starliner will launch on the United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

Fission Surface Power Technology Demonstration Unit

NASA Glenn Technician Mark Springowski works on a 10-kilowatt Stirling Power Conversion Unit, which is part of the Fission Surface Power Technology Demonstration Unit. This is a system level demonstration of a surface power system, which could potentially be used to support manned missions to the moon or Mars. A flight system would use 180 kilowatt nuclear fission reactor and four Stirling PCU’s to produce 40 kW of electricity for manned surface missions.

Advanced Plant Habitat Flight Unit #1

Inside a laboratory in the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, a quality technician checks the hardware for the Advanced Plant Habitat flight unit. The flight unit is an exact replica of the APH that was delivered to the International Space Station. Validation tests and post-delivery checkout was performed to prepare for space station in-orbit APH activities. The flight unit will be moved to the International Space Station Environmental Simulator to begin an experiment verification test for the science that will fly on the first mission, PH-01. Developed by NASA and ORBITEC of Madison, Wisconsin, the APH is the largest plant chamber built for the agency. It is a fully automated plant growth facility that will be used to conduct bioscience research on the space station.

SuperCam Mast Unit

SuperCam's mast unit before being installed atop the Perseverance rover's remote sensing mast. SuperCam fires a laser at rock or soil targets up to 20 feet (7 meters) away, and then analyzes the vaporized rock to reveal the composition. SuperCam's telescope peers out through a window seen on the right side of the unit, above a microphone (hidden by a red protective cover in this image), which will pick up the sounds of rocks being vaporized by the laser. The electronics are inside the gold-plated box on the left. The end of the laser peeks out from behind the left side of the electronics. https://photojournal.jpl.nasa.gov/catalog/PIA24208

Snow in northeastern United States

Snow covered the northeastern United States on last day of meteorological winter, 2014. Climatologists and meteorologists break seasons down into three-month groups, based on annual temperature and our calendar. This method is helpful for weather observing and forecasting, and for planning consistent agricultural dates, such as expected first frosts or best planting date. Meteorological winter – the season where temperatures are, on average, coldest and when snow is most likely to fall – runs from December 1 to February 28 in the United States and Canada. Winter can also be defined by the astronomical calendar, which is based on the rotation of the Earth around the sun. In this method, the seasons are defined by two solstices (times when the sun’s path is furthest from the Earth’s equator) and two equinoxes (the times when the sun passes directly above the equator). In the Northern Hemisphere, winter begins on the winter solstice, which falls on or around December 22 and ends on or around March 21, at the vernal (spring) equinox. On February 28, 2014, the Moderate Resolution Imaging Spectroradiometer aboard NASA’s Aqua satellite captured this true-color image of a sunny winter day in the northeastern United States. Snow stretches from Maine west to Indiana and south along the ridges of the Appalachian Mountains well into West Virginia. In Canada, the landscape appears greener, primarily because snow lies on conifers (evergreen) trees in the boreal forest regions. The Great Lakes, with the exception of Lake Ontario, are almost completely covered with ice.

The United States Flag Stands On The Surface Of Mars

The flag of the United States stands on the surface of Mars. It is mounted on the housing of NASA's Viking 1's nuclear power system. Also seen are the U.S. Bicentennial symbol and a student designed Viking emblem. The bright flat surface near the center is the seismometer container. This picture was taken on July 23 at about 2:30 p.m. Mars time. The view is west of the spacecraft and includes a series of low hills. The blocky hill in the center appears to be part of a crater rim. The dark, rocky stripes may be material ejected from the crater. The light areas are dune-like and may be accumulations of windblown sand or dust. http://photojournal.jpl.nasa.gov/catalog/PIA00388

Curiosity Views the Yardang Unit

NASA's Curiosity Mars rover captured this view of a geological region called the Yardang Unit using its Mast Camera, or Mastcam, on Nov. 2, 2024, the 4,352nd Martian day, or sol, of the mission. This mosaic is made up of 18 images that were stitched together after being sent back to Earth. The color has been adjusted to match lighting conditions as the human eye would see them on Earth. A yardang is an elongated ridge created by wind erosion. The Yardang Unit is a layer found at the uppermost reaches of the foothills at the base of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain that Curiosity has been ascending since 2014. The color, texture, and tilt of the layers in the Yardang Unit make it distinct from lower layers on the mountain. Mount Sharp is an exciting place for scientists to study because it's made up of a number of layers, each representing a distinct era in the climate of ancient Mars. https://photojournal.jpl.nasa.gov/catalog/PIA26472
