A NASA Mars Rover Landing banner is seen on the One Times Square video board as NASA's Perseverance rover begins its descent towards the surface of Mars, Thursday, Feb. 18, 2021 in New York City. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

Spectators in Times Square watch the video board of the Nasdaq MarketSite showing the live NASA TV broadcast as NASA InSight team members celebrate inside the Mission Support Area of NASA's Jet Propulsion Laboratory after receiving confirmation the lander successfully touched down on the surface of Mars, Monday, Nov. 26, 2018 in Times Square in New York City. The lander sent a signal affirming a completed landing sequence at approximately 3 p.m. EST (noon PST) after touching down on the western side of a flat, smooth expanse of lava called Elysium Planitila. InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to study the "inner space" of Mars: its crust, mantle, and core.

iss066e113865 (Jan. 15, 2022) --- A sample site is denoted for the SQuARE archaeological investigation with pieces of Kapton tape. This investigation studies how astronauts use objects in space over an extended period of time in space. The experiment adapts the standard archaeological technique on Earth called the “shovel test pit” by having crew members mark out square sample sites throughout the orbiting laboratory. Astronauts took picture of these sites at the same time every day, and then at randomly selected times. What we learn could inform design of future space habitats.

Technicians installed a special radiation vault onto the propulsion module of NASA Juno spacecraft. Each titanium wall measures nearly a square meter nearly 10 square feet in area and about 1 centimeter a third of an inch in thickness.

iss066e114158 (Jan. 15, 2022) --- NASA astronaut and expedition 66 Flight Engineer Kayla Barron snaps pictures of a sample “pit” aboard the International Space Station as part of the SQuARE experiment. This study is adapted from the standard archaeological technique on Earth called the “shovel test pit” and tracks the use and movement of objects in several sample sites throughout the orbiting laboratory. Crew members marked off the sample sites and took pictures at approximately the same every day, and then at randomly selected times. Scientists on the ground will analyze the images to understand how astronauts use objects and spaces over an extended period of time. What we learn could inform design of future space habitats.

S74-20831 (November 1973) --- A group of astronauts and their cosmonaut hosts are photographed sightseeing on Red Square in the heart of Moscow during a tour of the Soviet capital. The Americans were in the USSR to participate in Apollo-Soyuz Test Project familiarization training on the Soyuz systems at the Cosmonaut Training Center (Star City) near Moscow. Astronaut Thomas P. Stafford (light coat, black cap), commander of the American ASTP crew, was head of the U.S. delegation to Star City. Astronaut Eugene A. Cernan (on Stafford?s left, light coat) is the Special Assistant to the American Technical Director of ASTP. The sightseeing group is walking in the direction of Lenin?s Mausoleum. The structure in the background is the Cathedral of the Intercession (St. Basil?s) Museum. The historic Kremlin complex is to the right. PHOTO COURTESY: USSR ACADEMY OF SCIENCES

Today's VIS image shows part of the lowland plains north of the Elysium volcanic complex. Right angles are almost always created by tectonic forces. These linear depressions and the right angle intersections most likely were created in response to the volcanic activity that resulted in the uplifted surface and volcanoes of Elysium.

NASA Terra spacecraft imaged Iceberg B-15A, the largest iceberg in the world measuring about 11,000 square kilometers when it broke away from Western Antarctica Ross Ice Shelf in March 2000.

This enormous section of the Milky Way galaxy is a mosaic of images from NASA Wide-field Infrared Survey Explorer. The constellations Cassiopeia and Cepheus are featured in this 1,000-square degree expanse.

This image from NASA Terra spacecraft shows Palouse, a rich farming area of some 7,000 square kilometers, reminiscent of Tuscany. But instead of vineyards, the main crops are wheat and rapeseed.

NASA Juno spacecraft rests atop its rotation fixture awaiting transfer to a shipping crate prior to environmental testing; the large white square on the spacecraft right is largest of six microwave radiometer antennas, masked by protective covering.

NASA Wide-field Infrared Survey Explorer spacecraft is situated on a work stand. At left on the spacecraft is the fixed panel solar array. In front, the square is the HGA Slotted Array Ku-Band.

This image shows the calibration target for the Chemistry and Camera ChemCam instrument on NASA Curiosity rover. The calibration target is one square and a group of nine circles that look dark in the black-and-white image.

On Feb. 13, 2014, violent eruption of Kelud stratovolcano in Java, Indonesia sent volcanic ash covering an area of 70,000 square miles, prompting the evacuation of tens of thousands of people. This image is from NASA Terra spacecraft.

Erosional features are prominent in this view of southern Colorado taken NASA Shuttle Radar Topography Mission SRTM. The area covers about 20,000 square kilometers and is located about 50 kilometers south of Pueblo, Colorado.

The left image is an airbrush map of the surface of Ganymede from NASA Voyager data. The small square shows the location of Antum crater, target of the image from NASA Galileo spacecraft on the right.

It drains a watershed that spans eight countries and nearly 1.6 million square kilometers 600,000 square miles. The Zambezi also Zambeze is the fourth largest river in Africa, and the largest east-flowing waterway. The Operational Land Imager on the Landsat 8 satellite acquired this natural-color image of the Zambezi Delta on August 29, 2013. Sandbars and barrier spits stretch across the mouths of the delta, and suspended sediment extends tens of kilometers out into the sea. The sandy outflow turns the coastal waters to a milky blue-green compared to the deep blue of open water in the Indian Ocean. The Zambezi Delta includes 230 kilometers of coastline fronting 18,000 square kilometers (7,00 square miles) of swamps, floodplains, and even savannahs (inland). The area has long been prized by subsistence fishermen and farmers, who find fertile ground for crops like sugar and fertile waters for prawns and fish. Two species of endangered cranes and one of the largest concentration of buffalo in Africa -- among many other species of wildlife -- have found a haven in this internationally recognized wetland. However, the past six decades have brought great changes to the Zambezi Delta, which used to pour more water and sediment off of the continent. Hydropower dams upstream-most prominently, the Kariba and the Cahora Bassa-greatly reduce river flows during the wet season; they also trap sediments that would otherwise flow downstream. The result has been less water reaching the delta and the floodplains, which rely on pulses of nutrients and sediments from annual (and mostly benign) natural flooding. The change in the flow of the river affects freshwater availability and quality in the delta. Strong flows push fresh water further out into the sea and naturally keep most of a delta full of fresh (or mostly fresh) water. When that fresh flow eases, the wetlands become drier and more prone to fire. Salt water from the Indian Ocean also can penetrate further into the marsh, upsetting the ecological balance for aquatic plant and animal species. Researchers have found that the freshwater table in the delta has dropped as much as five meters in the 50 years since dams were placed on the river. Less river flow also affects the shape and extent of the delta. Today there is less sediment replenishing the marshes and beaches as they are scoured by ocean waves and tides. "What strikes me in this image is the suspended sediment offshore," said Liviu Giosan, a delta geologist at the Woods Hole Oceanographic Institution. "Sediment appears to be transferred from the delta offshore in plumes that not only originate in active river mouths but also from deactivated former mouths, now tidal channels. This shows the power of tidal scouring contributing to the slow but relentless erosion of the delta." http://photojournal.jpl.nasa.gov/catalog/PIA18155
