Martian dust devil analogues in the Mojave Desert #ASA183
In the Mojave Desert, the sun beats down on the ground and makes pockets of low pressure. Cool air rushes into these areas, where it warms and rises, creating vortices that pick up dust. These types of dust devils aren't limited to Earth: They are found on Mars at sizes reaching 1,600 meters in diameter. Dust devils could play a large role in the Martian climate, and they are crucial to un
Leidos Dynetics Team and Northrop Grumman to Collaborate on NASA Human Landing System Bid
Dynetics, a wholly-owned subsidiary of Leidos, has announced it has submitted a bid on the Human Landing System (HLS) Sustaining Lunar Development (SLD) contract for NASA's Artemis Mission. Northrop Grumman will join the Dynetics team in this pursuit. "We're excited to enter the competition to support NASA's Sustaining Lunar Development efforts, adding Northrop Grumman to our team," said L
Tiny underwater sand dunes may shed light on larger terrestrial and Martian formations
The English poet William Blake famously implored readers to "see the world in a grain of sand." In Physics of Fluids, by AIP Publishing, scientists from the University of Campinas, in Brazil, and the University of California, Los Angeles, have been doing just that - studying the "granular" dynamics of how crescent-shaped sand dunes are formed. Known as barchans, these formations are common
NASA's Perseverance rover gets the dirt on Mars
NASA's Perseverance rover snagged two new samples from the Martian surface on Dec. 2 and 6. But unlike the 15 rock cores collected to date, these newest samples came from a pile of wind-blown sand and dust similar to but smaller than a dune. Now contained in special metal collection tubes, one of these two samples will be considered for deposit on the Martian surface sometime this month as part
NSF-funded solicitation seeks physical science proposals to utilize ISS National Lab
For the eighth year, the Center for the Advancement of Science in Space, Inc. (CASIS) and U.S. National Science Foundation (NSF) have partnered to solicit transport phenomena and fluid dynamics research leveraging the International Space Station (ISS) National Laboratory. NSF will provide up to $3.6 million for multiple projects to utilize the space station's research facilities for fundam
Can plasma instability in fact be the savior for magnetic nozzle plasma thrusters
A research group has demonstrated that spontaneously excited plasma waves may be the solution to a long-associated problem with magnetic nozzle plasma thrusters, turning conventional thinking on its head. Details of their research were published in the journal Scientific Reports on December 5, 2022. In magnetic nozzle radio frequency thrusters, sometimes referred to as helicon thrust
New rocket successfully takes to outer space
Kuaizhou 11, the newest model of carrier rocket developed by China Aerospace Science and Industry Corp, carried out its first successful flight on Wednesday morning, lifting an experimental satellite into space, according to the company. The rocket blasted off at 9:15 am at the Jiuquan Satellite Launch Center in northwestern China's Gobi Desert and soon deployed the Xingyun Transport VDES
NASA advances Artemis Moon rocket production for future missions
NASA is moving forward with Space Launch System (SLS) production and assembly activities for future Artemis missions. The agency is optimizing manufacturing capabilities by enabling SLS core stage lead contractor Boeing to use facilities at NASA's Kennedy Space Center in Florida to perform some core stage assembly and outfitting activities beginning with the Artemis III rocket. In tandem,
Southern Launch and ATSpace return to launch up to two Kestrel I rockets before the end of the year
by Kurtis Eichler for The Lead After a severe electrical storm damaged an ATSpace rocket on the launch pad in November, the company has announced that repairs have been completed and they will attempt another launch in the coming weeks, followed by another already planned launch of a second rocket. ATSpace CEO Dr Yen Sen Chen said they were pleased to discover that the repairs required to
New lidar technique could help robotic vehicles land safely on Mars
In a new study, scientists demonstrate a new lidar technique that could help robotic vehicles avoid hazards when landing during future missions to Mars or the moon. The method uses flash lidar to record full 3D images with a single laser pulse, which prevents the motion blur that is present with traditional lidar approaches.
Farzin Amzajerdian from NASA Langley Research Center will present the new findings at the Optica Laser Congress, 11–15 December 2022. The presentation, titled "Development of a 3D Flash Lidar for Terrain Sensing and Safe Landing on Planetary Bodies," will be presented on-site and online in a hybrid format.
"Lidar technology plays a critical role in future missions to the moon, Mars, and other solar system bodies since they require precision safe landing at specific locations where valuable resources may be found or may lead to important scientific discoveries," said principal investigator, Farzin Amzajerdian, Ph.D.
A streamlined design
Flash lidar is useful for several purposes throughout the process of landing robotic vehicles. As a vehicle descends to a surface, flash lidar can be used to generate 3D terrain maps from an altitude of several kilometers to reduce position error.
