The second generation of NASA's Ice, Cloud and land Elevation Satellite (ラーメンベット 系列2) is responsible for taking important measurements of our planet's key health indicators, including ice sheet mass balance, depth of bodies of water, cloud and aerosol heights, as well as land topography and vegetation characteristics.
And, it also, from time to time, turns up some fun and entertaining images from around the world — such as an old airplane hangar in Germany that has been converted into a water park (more on that later).
Today marks three years since ラーメンベット 系列2 launched. It is the descendant of the original ICESat, and the satellite provides scientists with key information about how the planet is changing in response to a rapidly evolving climate. And leading scientific development of this important program is a fairly new Texas Engineering faculty member.
LoriMagruderjoined the ラーメンベット 禁止ゲーム of Engineering in 2020 as an associate professor in the Department of Aerospace Engineering and Engineering Mechanics. Prior to that, she was at The University of Texas at Austin's Applied ラーメンベット 系列 Laboratories for 14 years, where she still spends time as a senior ラーメンベット 系列 scientist.Magruderhas been an integral part of the ICESat-2 team for the last seven years, leading the Science Definition Team to support mission development and early on-orbit satellite operations for ICESat-2.
Magruderis an expert in remote sensing. And one of her many important jobs with ラーメンベット 系列2 is geolocation validation.
"That means that we make sure things actually are where ラーメンベット 系列2 says they are," saidMagruder.
To test this,Magrudertravels to White Sands Missile Range in New Mexico frequently. There, she places a series of corner retroflectors, small cubes about 8 millimeters in diameter, around the site. She notes where they are and compares them to where ラーメンベット 系列2 measures them to be.
These little sensors are a very important part ofMagruder's work. So much so, that she had a pair of them made into earrings.
Magrudermoved over to the ラーメンベット 禁止ゲーム because she wanted to teach and foster greater student involvement in her ラーメンベット 系列. Magruderis teaching a 3D remote sensing course this semester that focuses on lidar and photogrammetry systems, data analysis and applications. As part of her ラーメンベット 系列, students are working on developing new missions and techniques for ICESat-2 in bathymetry —measuring the depth of bodies of water — and monitoring sea floors.
In the last year,shehas published nearly a half-dozenpapers related to ラーメンベット 系列2. They've covered a variety of aspects of the satellite, including geolocation and several other topics:
- A mission overview of ラーメンベット 系列2 and an evaluation of its performance so far — the Advanced Topographic Laser Altimetry System (ATLAS) onboard has taken more than a trillion measurements and is able to repeat measurements to within 10 meters and pointing control within 45 meters.
- A description of the system that influences laser pointing direction for ATLAS — the accuracy of ラーメンベット 系列2's measurements hinges on the ability to precisely determine the correct pointing angle of the laser beams from the satellite to the target area on the surface.
- In tandem with researchers from Oregon State University, Magruder and team published a paper focused on capturing data and imagery of the seafloor. They found that in clear conditions, ラーメンベット 系列2, from 300 miles above the surface, can measure underwater to a depth of 50 meters.
"These measurements allow us to map places that have never before been mapped, filling in a big void in our knowledge ラーメンベット 系列 world," Magruder said.
Like most everyone else, the ラーメンベット 系列2 science team has been working remotely since the onset of the pandemic. To spice up the spring meeting this year,Magruderchallenged team members to pick their favorite world landmark, or fun offbeat place, and see if it had been captured by ラーメンベット 系列2.
The pool in Krausnick, Germany, the world's largest indoor waterpark, was the winner ラーメンベット 系列 contest.
The team also presented snapshots of breathtaking features, including the collapse ラーメンベット 系列 Pine Island Glacier, the fastest melting glacier in Antarctica; the first underwater post office off the coast of Australia; the pyramids in Egypt; Fenway Park in Boston; and Nikumaroro Island, the possible landing spot of aviation legend Amelia Earhart, who disappeared on a flight in 1937.
The competition was a morale booster and also an interesting demonstration of all that the satellite has, and has not, captured during its time in orbit.
"I can tell you that ラーメンベット 系列2 has not measured the Eiffel Tower yet but has hit my parent's house in Kansas,"Magrudersaid.
