\rNASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will measure the average annual elevation change of land ice covering Greenland and Antarctica to within the width of a pencil, capturing 60,000 measurements every second.
\r
\r“ICESat-2’s new observational technologies will advance our knowledge of how the ice sheets of Greenland and Antarctica contribute to sea level rise while also helping us understand the connection of sea ice loss to the global system,” said Thomas Wagner, cryosphere program scientist in NASA’s Science Mission Directorate.\r
\rICESat-2 will extend and improve upon NASA's 15-year record of monitoring the change in polar ice heights, which started in 2003 with the first ICESat mission and continued in 2009 with NASA’s Operation IceBridge, an airborne research campaign that monitors the accelerating rate of change.\r
\rICESat-2 represents a major technological leap in our ability to measure changes in ice height. Its Advanced Topographic Laser Altimeter System (ATLAS) measures height by timing how long it takes individual light photons to travel from the spacecraft to Earth and back.\r
NASA will host a media teleconference at 1 p.m. EDT Wednesday, Aug. 22, to discuss the upcoming launch of the Ice, Cloud and land Elevation Satellite (ICESat-2), which will fly NASA's most advanced laser altimeter to measure Earth’s changing ice. The teleconference will stream live on NASA's website.
ICESat-2 is scheduled to launch Sept. 15 from Vandenberg Air Force Base.
The briefing participants are:
• Tom Wagner, cryosphere program scientist in the Science Mission Directorate (SMD) at NASA Headquarters
• Richard Slonaker, ICESat-2 program executive in SMD
• Doug McLennan, ICESat-2 project manager at NASA’s Goddard Space Flight Center
• Donya Douglas-Bradshaw, Advanced Topographic Laser Altimeter System (ATLAS) instrument project manager at Goddard
• Tom Neumann, ICESat-2 deputy project scientist at Goddard

"description": "Data visualization featuring precise map of Mercer and Conway subglacial lakes in West Antarctica. The visualization sequence starts with a view of the Americas and slowly zooms into the suture between the Mercer and Whillans ice streams. Surface-height anomaly data from NASA's ICESat-2 mission provide critical insight for the drain-fill cycles of subglacial lakes and aid in the discovery of two new water bodies within the same region. This data-driven visualization includes labels of ice formations close to the area of interest and repeats playback of the segment of the subglacial lakes surface-height anomalies. || SubglacialLakesCompositex2_4K60fps_0904_print.jpg (1024x576) [88.8 KB] || SubglacialLakesCompositex2_4K60fps_0904.png (3840x2160) [5.9 MB] || Compositex2 (1920x1080) [0 Item(s)] || SubglacialLakesCompositex2_HD60fps.mp4 (1920x1080) [58.4 MB] || SubglacialLakesCompositex2_1080p30.mp4 (1920x1080) [53.8 MB] || SubglacialLakesCompositex2_HD60fps.webm (1920x1080) [6.9 MB] || Compositex2_4K (3840x2160) [0 Item(s)] || SubglacialLakesCompositex2_4K60fps.mp4 (3840x2160) [58.5 MB] || SubglacialLakesCompositex2_4K30fps.mp4 (3840x2160) [182.4 MB] || SubglacialLakesCompositex2_1080p30.mp4.hwshow [200 bytes] || ",
