The water-world Enceladus appears here to sit atop Saturn rings like a drop of dew upon a leaf in this view from NASA Cassini spacecraft.
Researcher Dr. Yi Li developed a technique to manipulate certain characteristics of plant growth such as anit-senescence. For example, the tobacco leaf was clipped from a transgenic plant (right), and a wildtype plant (left). During ground-based laboratory studies, both leaves were left in a darkened area for 4 months. When retrieved, the wildtype plant leaf was dried-out and the transgenic leaf remained fresh and green. A variation of this technology that involves manipulating plant hormones has been conducted in space-based studies on tomato plants through BioServe Space Technologies. The transport and distribution of auxin, an important plant hormone has shown to be influenced by microgravity, which could lead to improving the quality of fruits and vegetables grown on Earth.

KENNEDY SPACE CENTER, FLA. -- Workers in the Defense Satellite Communication Systems Processing Facility (DPF), Cape Canaveral Air Station (CCAS), move to the workstand the second conical section leaf of the payload transportation container for Deep Space 1. The first flight in NASA's New Millennium Program, Deep Space 1 is designed to validate 12 new technologies for scientific space missions of the next century, including the engine. Propelled by the gas xenon, the engine is being flight-tested for future deep space and Earth-orbiting missions. Deceptively powerful, the ion drive emits only an eerie blue glow as ionized atoms of xenon are pushed out of the engine. While slow to pick up speed, over the long haul it can deliver 10 times as much thrust per pound of fuel as liquid or solid fuel rockets. Other onboard experiments include software that tracks celestial bodies so the spacecraft can make its own navigation decisions without the intervention of ground controllers. Deep Space 1 will complete most of its mission objectives within the first two months, but will also do a flyby of a near-Earth asteroid, 1992 KD, in July 1999. Deep Space 1 will be launched aboard a Boeing Delta 7326 rocket from Launch Pad 17A, CCAS

The growth chamber was used as a control unit for Veggie and procedures were followed identical to those being performed on Veggie and the Veg-01 experiment on the International Space Station. The chamber mimicked the temperature, relative humidity and carbon dioxide concentration of those in the Veggie unit on the space station. Veggie and Veg-01 were delivered to the space station aboard the SpaceX-3 mission. Veggie is the first fresh food production system delivered to the station. Six plant pillows, each containing outredgeous red romaine lettuce seeds and a root mat were inserted into Veggie. The plant chamber's red, blue and green LED lights were activated. The plant growth was monitored for 33 days. On June 10, at the end of the cycle, the plants were carefully harvested, frozen and stored for return to Earth by Expedition 39 flight engineer and NASA astronaut Steve Swanson.

Youngstown, Ohio high school student, W. Brian Dunlap (center), discusses with Dr. Robert Head (right), and Henry Floyd, both of the Marshall Space Flight Center (MSFC), his experiment to be performed aboard the Skylab the following year. His experiment, “Wave Motion Trough A Liquid in Zero Gravity” used a container attached to the end of a leaf spring which was oscillated at specific rates using two thickness differentiated types of liquids. Dunlap was among 25 winners of a contest in which some 3,500 high school students proposed experiments for the following year’s Skylab mission. The nationwide scientific competition was sponsored by the National Science Teachers Association and the National Aeronautics and Space Administration (NASA). The winning students, along with their parents and sponsor teachers, visited MSFC where they met with scientists and engineers, participated in design reviews for their experiments, and toured MSFC facilities. Of the 25 students, 6 did not see their experiments conducted on Skylab because the experiments were not compatible with Skylab hardware and timelines. Of the 19 remaining, 11 experiments required the manufacture of additional equipment. The equipment for the experiments was manufactured at MSFC.

Converse was among 25 winners of a contest in which some 3,500 high school students proposed experiments for the following year’s Skylab mission. His experiment, “Zero Gravity Mass Measurement” used a simple leaf spring with the mass to be weighed attached to the end. An electronic package oscillated the spring at a specific rate and the results were recorded electronically.

University of California, Santa Barbara (UCSB) student Piper Lovegreen calibrates a sensor to measure leaf chlorophyl content of vegetation at the Jack and Laura Dangermond Preserve in Santa Barbara County on March 23, 2022. Lovegreen is among the researchers working on the Surface Biology and Geology High-Frequency Time Series (SHIFT) campaign, which is jointly led by NASA's Jet Propulsion Laboratory, UCSB, and The Nature Conservancy. Operating between late February and late May 2022, SHIFT combines the ability of airborne science instruments to gather data over widespread areas with the more concentrated observations scientists conduct in the field to study the functional characteristics, health, and resilience of plant communities. The sampling and analysis done by researchers on the ground and in the ocean is intended to validate data taken by AVIRIS-NG (Airborne Visible/Infrared Imaging Spectrometer-Next Generation). The instrument, designed at JPL, is collecting spectral data of vegetation it observes during weekly flights in an aircraft over a 640-square-mile (1,656-square-kilometer) study area in Santa Barbara County and coastal Pacific waters. The campaign is a pathfinder for NASA's proposed Surface Biology and Geology (SBG) mission. SHIFT will help scientists design data collection and processing algorithms for that mission, which would launch no earlier than 2028. The SHIFT data is also intended to support the research and conservation objectives of The Nature Conservancy, which owns the Dangermond Preserve, and UCSB, which operates the Sedgwick Reserve, another nature preserve within the study area. More than 60 scientists from institutions around the U.S. have indicated they intend to use the SHIFT data in their research. https://photojournal.jpl.nasa.gov/catalog/PIA25142

On July 3, 1936, President Franklin Delano Roosevelt stood amidst the crowd in Big Meadows and officially dedicated Shenandoah National Park in Virginia. The Thematic Mapper on the Landsat satellite captured this view of the heart of Shenandoah National Park on October 10, 2010, at the height of the fall “leaf-peeping” season. The orange and brown swath across the image highlights the hilly backbone of the park, where leaves had turned to their fall colors. The 169-kilometer (105-mile) Skyline Drive that meanders across the crest of the ridge is often jammed with tourists in autumn. The park includes more than 518 miles of hiking trails, including more than 100 miles of the Appalachian Trail. The highest peak is Hawksbill Mountain at 4,051 feet (1,235 m), but the most popular with hikers is Old Rag Mountain. A circuitous eight-mile (13 kilometer) trail leads to an exposed, rocky summit 3,291 feet (1,003 meters) above sea level. The 2,200 foot elevation change from base to summit, combined with several rock scrambles, make Old Rag not only the most popular but also the most dangerous hike.

These are two false-color composites of Raco, Michigan, located at the eastern end of Michigan upper peninsula, west of Sault Ste. Marie and south of Whitefish Bay on Lake Superior. The two images (centered at 46.39 degrees north latitude, 84.88 degrees west longitude) show significant seasonal changes in the mid-latitude region of mixed deciduous and coniferous forests. The images were acquired by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the shuttle Endeavour on the sixth orbit of each mission. In these images, red is L-band (23 cm) with horizontal/vertical polarization; green is C-band (6 cm) with horizontal/vertical polarization; blue is C-band with horizontal/horizontal polarization. The region shown is largely forested and includes a large portion of Hiawatha National Forest, as well as an agricultural region near the bottom of each image. In early April, the area was snow-covered with up to 50 centimeters (19.5 inches) of snow in forest clearings and agricultural fields. Buds had not yet broken on deciduous trees, but the trees were not frozen and sap was generally flowing. Lake Superior, in the upper right, and the small inland lakes were frozen and snow-covered on April 9, 1994. By the end of September, deciduous trees were just beginning to change color after a relatively wet period. Leaf loss was estimated at about 30 percent, depending on the species, and the soil was moist to wet after a heavy rainfall on September 28, 1994. Most agricultural fields were covered with grasses of up to 60 centimeters (23 inches) in height. In the two images the colors are related to the types of land cover (i.e. vegetation type) and the brightness is related to the amount of plant material and its relative moisture content. Significant seasonal changes between early spring and early fall are illustrated by this pair of images. For the agricultural region near the bottom of the images, the change from snow-cover to moist soil with short vegetation cover is shown by the color change from blue to green and blue. The green color corresponds to significant increases in vegetation cover and field-to-field differences in blue are the result of differences in surface roughness and soil moisture. In the forested areas, many of the conifer forests appear similar in both images (red pine forests appear red in both images). However, there is more blue and green in the September 30, 1994 image as a consequence of greater foliage and more moisture in the forest crowns. Lowland conifer forests (spruce and northern white cedars) appear as bright green in both images. Deciduous forests produce very strong radar returns at these frequencies and polarization combinations, resulting in a nearly white appearance on the images (the specific color mix is related to the local species mix). In the September 30, 1994 image, the areas of deciduous forest appear darker than in the April image because of the weaker radar signal from the foliage in the crown layer. The clear-cut areas (shown in April by the irregularly shaped dark areas in the center) change dramatically in appearance due to loss of snow cover and increases in soil moisture and vegetation cover by the end of September. http://photojournal.jpl.nasa.gov/catalog/PIA01730
This composite image contains the deepest X-ray image ever made of the spectacular star forming region called 30 Doradus. By combining X-ray data from NASA’s Chandra X-ray Observatory (blue and green) with optical data from NASA’s Hubble Space Telescope (yellow) and radio data from the Atacama Large Millimeter/submillimeter Array (orange), this stellar arrangement comes alive.
