MOJAVE, Calif. — Video capture during future lunar landings could play an important role in contributing to researchers’ understanding of disturbances in lunar surface materials – called regolith – caused by the lander’s rocket plume. With support from NASA’s Flight Opportunities program, on Oct. 14, 2021, researchers from Los Angeles-based Zandef Deksit put a high-tech video capture and regolith sensor payload called ExoCam to the test. The desert environment of Mojave, California, provided a stand-in for the surface of the Moon, and the Xodiac vertical takeoff vertical landing (VTVL) platform from Masten Space Systems was the test vehicle.
Simulating the movement of a lunar lander, the VTVL vehicle enabled researchers from Zandef Deksit and co-investigators from Honeybee Robotics to test an ejection mechanism to jettison the ExoCam onto the desert surface at specific altitudes just before landing. Along with calculations to account for lunar gravity, this helped the team understand the limit of how far from a planetary surface they would need to eject the payload in order for it to survive landing and function properly.
Once on the ground, the payload’s camera captured video footage from the unique vantage point of the desert surface. The ExoCam also utilized a regolith sensor developed by co-investigators at Arizona State University to capture data about the quantity of regolith particles picked up by the vehicle’s rocket plume, as well as the speed at which they were propelled as the lander descended onto the surface.
About Flight Opportunities
Flight Opportunities rapidly demonstrates promising technologies for space exploration, discovery, and the expansion of space commerce through suborbital testing with industry flight providers. The program is funded by NASA’s Space Technology Mission Directorate (STMD) at the agency’s Headquarters in Washington, and managed at NASA’s Armstrong Flight Research Center in Edwards, California. NASA’s Ames Research Center in California’s Silicon Valley manages the solicitation and evaluation of technologies to be tested and demonstrated on commercial flight vehicles.
BEIJING (Deep Blue Aerospace PR) — On October 13, the Deep Blue Aerospace “Nebula-M” test arrow 1 completed the 100-meter vertical take-off and landing (VTVL) flight test at the Tongchuan Test Base in Shaanxi Province, achieving all test assessment targets and the test mission was a complete success.
This VTVL flight test was completed by the same launch rocket in a short period of time after Deep Blue Aerospace completed the 10-meter VTVL flight test at the end of July, creating the first 100-meter liquid oxygen kerosene rocket recovery and reuse flight record in China. It demonstrates Deep Blue Aerospace’s responsiveness and organizational capabilities for rapid maintenance of the rocket body and rapid organization of re-flight. At the same time, it has accumulated valuable data and engineering experience for continuing to organize high-altitude and orbital-level vertical recovery tests.
MOJAVE, Calif. (NASA PR) — A navigation doppler lidar (NDL) technology originally developed by NASA was demonstrated on a flight test on Sept. 10 with support from the Flight Opportunities program, part of NASA’s Space Technology Mission Directorate.
With roots at NASA’s Langley Research Center in Hampton, Virginia, the technology was licensed in 2016 by Psionic for both terrestrial and space applications, and both the company and Langley continue to evolve and advance the innovation for upcoming lunar missions.
Sometime in 2020, if all goes according to plan, British billionaire Richard Branson will board Virgin Galactic’s SpaceShipTwo VSS Unity at Spaceport America in New Mexico and take the first commercial suborbital space flight in history.
The landmark flight, which Virgin has been trying to conduct for 15 years, will also be the culmination of a 30-year effort by New Mexico to become a commercial space power.
Via my friend Clark Lindsey over at HobbySpace comes some rather startling news:
SpaceX is developing an 106-foot tall reusable vertical takeoff and vertical landing (VTVL) rocket called Grasshopper based upon the first stage of the Falcon 9 rocket. It has applied for an experimental permit to conduct a series of flights up to 11,500 feet at its engine testing facility in McGregor, Texas.
The Grasshopper RLV consists of a Falcon 9 Stage 1 tank, a Merlin-1D engine, four steel landing legs, and a steel support structure. Carbon overwrapped pressure vessels (COPVs), which are filled with either nitrogen or helium, are attached to the support structure. The Merlin-1D engine has a maximum thrust of 122,000 pounds. The overall height of the Grasshopper RLV is 106 feet, and the tank height is 85 feet.
