Paresev 1A and Stearman tow plane on lakebed.

The Paresev 1-A (Paraglider Research Vehicle) and the tow airplane, 450-hp Stearman sport Biplane, sitting on Rogers dry lakebed, Edwards, California. The control system in the Paresev 1-A had a more conventional control stick position and was cable-operated; the main landing gear used shocks and bungees with the 100-square-foot wing membrane being made of 6-ounce unsealed Dacron.

The M2-F3 Lifting Body is seen here on the lakebed next to the NASA Flight Research Center (FRC--later Dryden Flight Research Center), Edwards, California. The May 1967 crash of the M2-F2 had torn off the left fin and landing gear. It had also damaged the external skin and internal structure. Flight Research Center engineers worked with Ames Research Center and the Air Force in redesigning the vehicle with a center fin to provide greater stability. Then Northrop Corporation cooperated with the FRC in rebuilding the vehicle. The entire process took three years.

The M2-F3 Lifting Body is seen here on the lakebed at the NASA Flight Research Center (FRC--later the Dryden Flight Research Center), Edwards, California. After a three-year-long redesign and rebuilding effort, the M2-F3 was ready to fly. The May 1967 crash of the M2-F2 had damaged both the external skin and the internal structure of the lifting body. At first, it seemed that the vehicle had been irreparably damaged, but the original manufacturer, Northrop, did the repair work and returned the redesigned M2-F3 with a center fin for stability to the FRC.

The M2-F3 Lifting Body is seen here on the lakebed next to the NASA Flight Research Center (later the Dryden Flight Research Center), Edwards, California. Redesigned and rebuilt from the M2-F2, the M2-F3 featured as its most visible change a center fin for greater stability. While the M2-F3 was still demanding to fly, the center fin eliminated the high risk of pilot induced oscillation (PIO) that was characteristic of the M2-F2.

The HL-10 Lifting Body is seen here in flight over Rogers Dry lakebed. Like the other lifting bodies, the HL-10 made a steep descent toward the lakebed, followed by a high-speed landing. This was due to the vehicle's low lift-over-drag ratio. The first 11 flights of the HL-10 were unpowered, flown to check the vehicle's handling and stability before rocket-powered flights began using the XLR-11 rocket engine.

Pilot and Paresev 1 preparing for a landing on the Rogers dry lakebed in 1962 at Edwards Air Force Base, California. The flight program began with ground tow tests. Several tows were made before liftoff was attempted to check the control rigging and to familiarize the pilot with the vehicle’s ground stability. As the pilot’s confidence and experience increased, tow speeds were also increased until liftoff was attained. Liftoff was at about 40 knots indicated airspeed (kias).

Following the first M2-F1 airtow flight on 16 August 1963, the Flight Research Center used the vehicle for both research flights and to check out new lifting-body pilots. These included Bruce Peterson, Don Mallick, Fred Haise, and Bill Dana from NASA. Air Force pilots who flew the M2-F1 included Chuck Yeager, Jerry Gentry, Joe Engle, Jim Wood, and Don Sorlie, although Wood, Haise, and Engle only flew on car tows. In the three years between the first and last flights of the M2-F1, it made about 400 car tows and 77 air tows.

After initial ground-tow flights of the M2-F1 using the Pontiac as a tow vehicle, the way was clear to make air tows behind a C-47. The first air tow took place on 16 August 1963. Pilot Milt Thompson found that the M2-F1 flew well, with good control. This first flight lasted less than two minutes from tow-line release to touchdown. The descent rate was 4,000 feet per minute.

Bruce A. Peterson standing beside the M2-F2 lifting body on Rogers Dry Lake. Peterson became the NASA project pilot for the lifting body program after Milt Thompson retired from flying in late 1966. Peterson had flown the M2-F1, and made the first glide flight of the HL-10 heavy-weight lifting body in December 1966. On May 10, 1967, Peterson made his fourth glide flight in the M2-F2. This was also the M2-F2's 16th glide flight, scheduled to be the last one before the powered flights began. However, as pilot Bruce Peterson neared the lakebed, the M2-F2 suffered a pilot induced oscillation (PIO). The vehicle rolled from side to side in flight as he tried to bring it under control. Peterson recovered, but then observed a rescue helicopter that seemed to pose a collision threat. Distracted, Peterson drifted in a cross-wind to an unmarked area of the lakebed where it was very difficult to judge the height over the lakebed because of a lack of the guidance the markers provided on the lakebed runway. Peterson fired the landing rockets to provide additional lift, but he hit the lakebed before the landing gear was fully down and locked. The M2-F2 rolled over six times, coming to rest upside down. Pulled from the vehicle by Jay King and Joseph Huxman, Peterson was rushed to the base hospital, transferred to March Air Force Base and then the UCLA Hospital. He recovered but lost vision in his right eye due to a staph infection.

This evenly layered rock photographed by the Mast Camera Mastcam on NASA Curiosity Mars Rover on Aug. 7, 2014, shows a pattern typical of a lake-floor sedimentary deposit not far from where flowing water entered a lake.

Holden Crater was once filled by at least two different lakes. The sediments deposited in those lakes are relatively light-toned where exposed, as seen in this observation from NASA's Mars Reconnaissance Orbiter. Each layer represents a different point in time and perhaps a changing environment for Martian life, if it existed. The elongated ridges with sharp crests are sand dunes.

ISS028-E-035137 (30 Aug. 2011) --- Owens Lake in California is featured in this image photographed by an Expedition 28 crew member on the International Space Station. This photograph highlights the mostly dry bed of Owens Lake, located in the Owens River Valley between the Inyo Mountains and the Sierra Nevada. Shallow groundwater, springs, and seeps support minor wetlands and a central brine pool. Two bright red areas along the margins of the brine pool indicate the presence of halophilic, or salt-loving organisms known as Achaeans. Grey and white materials within the lake bed are exposed lakebed sediments and salt crusts. The towns of Olancha and Lone Pine are delineated by the presence of green vegetation indicating a more constant availability of water. According to scientists, the present-day Owens Lake was part of a much larger lake and river system that existed during the Pleistocene Epoch (approximately 3 million to approximately 12,000 years ago) along the current northeastern border of California with Nevada. Meltwater from alpine glaciers in the Sierra Nevada filled the regional valleys of the Basin and Range to form several glacial lakes that were ancestral to the now-dry lakebeds (or playas) of Owens, Searles Lake, and China Lake. While Searles and China Lakes dried out due to regional changes to a hotter and drier climate over thousands of years, Owens Lake became desiccated largely due to the diversion of Owens River water in the early 20th century to serve the needs of the City of Los Angeles, CA located 266 kilometers to the south. Following complete desiccation of the lakebed in 1926, significant amounts of windblown dust were produced ? indeed, the term ?Keeler fog? was coined by residents of the now largely abandoned town on the eastern side of Owens Lake due to the dust. In addition to adverse health effects on local residents, dust from Owens Lake has been linked to visibility reduction in nearby national parks, forests, and wilderness areas. Recently, efforts to control dust evolution from the lakebed have been undertaken by the City of Los Angeles.

A photo of model airplane builders James B. Newman and Robert L. McDonald preparing for a flight with models of the M2-F2 and a “Mothership”. In 1968 a test flight was made on the Rosamond dry lakebed, Rosamond, California. The original idea of lifting bodies was conceived about 1957 by Dr. Alfred J. Eggers, Jr., then the assistant director for Research and Development Analysis and Planning at the National Advisory Committee for Aeronautics' Ames Aeronautical Laboratory, Moffett Field, California. Nose cone studies led to the design known as the M-2, a modified half-cone, rounded on the bottom and flat on top, with a blunt, rounded nose and twin tail fins. To gather flight data on this configuration, models were found to be an effective method. A special twin-engined, 14-foot model “mothership” was used for carrying the M2-F2 model to altitude and a launch, much as was being done with the B-52 for the full-scale lifting bodies. Jim (on the left) will fly the “mothership” and Bob will take control of the M2-F2 at launch and fly it to a landing on the lakebed.

Based out of NASA’s Glenn Research Center in Cleveland, the Pilatus PC-12 is flying over the compass rose in the Roger’s Dry Lakebed at NASA’s Armstrong Flight Research Center, in Edwards, California. The compass rose is more than 4,000 feet in diameter and aligned to magnetic north, to test navigation equipment on aircraft. The Pilatus PC-12 tests communications technology for the emerging Advanced Air Mobility ecosystem. Pilots and crew from both centers perform familiarization flights to prepare for Automatic Dependent Surveillance Broadcast (ADS-B) systems tests between the aircraft and ping-Stations on the ground at Armstrong Flight Research Center. These flights are the first cross-center activity with the Pilatus-PC-12 at Armstrong Flight Research Center.

The X-40 sub-scale technology demonstrator and its U.S. Army CH-47 Chinook helicopter mothership fly over a dry lakebed runway during a captive-carry test flight from NASA's Dryden Flight Research Center, Edwards, California. The X-40 is attached to a sling which is suspended from the CH-47 by a 110-foot-long cable during the tests, while a small parachute trails behind to provide stability. The captive carry flights are designed to verify the X-40's navigation and control systems, rigging angles for its sling, and stability and control of the helicopter while carrying the X-40 on a tether. Following a series of captive-carry flights, the X-40 made free flights from a launch altitude of about 15,000 feet above ground, gliding to a fully autonomous landing. The X-40 is an unpowered 82 percent scale version of the X-37, a Boeing-developed spaceplane designed to demonstrate various advanced technologies for development of future lower-cost access to space vehicles.

Lake Enriquillo is a hypersaline lake in the Dominican Republic. In 2004, the lake covered an area of 164 square kilometers; by 2011, it had doubled in size and grown to 350 km2, inundating farmland and homes. Various reasons for the flooding include increases in rainfall; increase of sediments going into the lake, raising the lakebed; and milder temperatures, reducing surface evaporation. The lake is home to the largest population of American crocodiles in the Caribbean. The images were acquired October 26, 2003 and June 10, 2017, cover an area of 22.7 by 45.4 km, and are located at 18.5 degrees north, 71.6 degrees west.

The eastern shore of Lake Salda in Turkey is a good analog for what an ancient lake may have looked like at Jezero Carter on Mars. The white sands and rocks are carbonate minerals that precipitated in the lake. The terraces on the right are old shorelines from when the lake levels were higher, where dried-out sediments have now cemented. These types of deposits might be present along the former shorelines at Jezero. What's more, these deposits might contain signs of microbes, if they ever existed on the Red Planet. NASA's Mars 2020 Perseverance mission will search for signs of ancient life in an dried-up lakebed on the surface of Mars. https://photojournal.jpl.nasa.gov/catalog/PIA24375

STS030-S-123 (8 May 1989) --- The Space Shuttle Atlantis glides toward a landing on the Mojave Desert after spending just over four full days in space. Aboard were astronauts David. M. Walker, Ronald J. Grabe, Norman E. Thagard, Mary L. Cleave and Mark C. Lee. Moments later, the spacecraft?s landing gear came to a stop at 12:44:33 P.M. (PDT), 8 May 1989. It landed on runway 22, a concrete facility, like a number of other NASA flights. Still others have landed on unpaved dry lakebed strips.

STS030-S-132 (8 May 1989) --- Crewmembers who spent just over four full days in space aboard Space Shuttle Atlantis egress their temporary home for a welcome meeting with terra firma. Pictured, from bottom of steps to top, are astronauts David M. Walker, Ronald J. Grabe, Norman E. Thagard, Mary L. Cleave and Mark C. Lee.

Aboard a truck and ready for a test flight is the Paresev 1-C on the ramp at the NASA Flight Research Center, Edwards, California. The half-scale version of the inflatable Gemini parawing was pre-flighted by being carried across the Rosamond dry lakebed on the back of a truck before a tow behind a International Harvester Carry-All. The inflatable center spar ran fore and aft and measured 191 inches, two other inflatable spars formed the leading edges. The three compartments were filled with nitrogen under pressure to make them rigid. The Paresev 1-C was very unstable in flight with this configuration.
