SpaceX Revs Its Engines as It Gets Closer to Crewed Flight Paul Hennessy/NurPhoto/Getty Images Last Thursday, a shiny new SpaceX Falcon 9 rocket sat perched atop NASA’s historic Pad 39A, at Florida’s Kennedy Space Center, waiting to briefly fire its engines.
(In the case of our moon, astronomers think it once whirled faster about its axis.) But over time, gravity from our planet exerted torque on bulges in the lunar surface, forcing its rotation into synchronization with its orbital period.
NASA Lands Its InSight SpacecraftNASA/JPL-CaltechAfter a six-month journey across hundreds of millions of miles of deep space, NASA's InSight spacecraft—a mission nearly ten years and close to $1 billion in the making—landed successfully on the surface of Mars on Monday, touching down on the planet's surface just a few minutes before 12:00 pm PT.In the final moments of the spacecraft’s descent, the mission control room at NASA's Jet Propulsion Laboratory was silent as updates on InSight's status blared over the PA system: "Altitude 300 meters… 200 meters… 80 meters… 60 meters … 50 meters, constant velocity 37 meters… 30 meters … 20 meters… 17 meters… standing by for touchdown… Touchdown confirmed!
How and Where to Watch NASA's InSight Finally Land on MarsNASA/JPL-CaltechOn Monday, November 26th, following a six-month journey across hundreds of millions of miles of deep space, NASA's InSight spacecraft will arrive at Mars in suitably dramatic fashion, hitting the top of the planet's atmosphere at 12,300 miles per hour—several times faster than a speeding bullet—shortly before 12:00 pm PST (3:00 pm EST).If all goes as planned, it will take InSight (short for Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport) just seven minutes to decelerate completely and alight on Mars' surface.
Once it settles into orbit 310 miles above the Earth, the satellite will start collecting data using a specially designed laser device that will give scientists more data about exactly where ice is melting and how fast.The NASA satellite will scan the Earth’s surface using six green laser beams to measure glaciers and floating sea ice.
"When I saw the first land images of inland water bodies, I was amazed at their quality," said Chris Ruf, CYGNSS's principal investigator at the University of Michigan in Ann Arbor. The CYGNSS satellites measure wind speed by determining how choppy the water is from a microwave signal bounced off the ocean surface.
The Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra satellite passed over California on July 27 and July 29, observing the Carr Fire on July 27 and the Ferguson Fire on July 29.
NASA's Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station(ECOSTRESS) has captured new imagery of three wildfires burning in California and Nevada -- the first image of its kind to be taken by the agency's newest Earth-observing mission.
New images made with data acquired by the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite show the high concentrations of carbon monoxide emitted from the fires (in orange/red) between July 29 and August 8.
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 mechanism of abrupt thaw and thermokarst lake formation matters a lot for the permafrost-carbon feedback this century," said first author Katey Walter Anthony at the University of Alaska, Fairbanks, who led the project that was part of NASA’s Arctic-Boreal Vulnerability Experiment (ABoVE), a ten-year program to understand climate change effects on the Arctic.
NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will provide scientists with height measurements that create a global portrait of Earth's third dimension, gathering data that can precisely track changes of terrain including glaciers, sea ice, and forests.
The red points overlaid on the image designate those areas that by using thermal bands detect actively burning fires. NASA's Earth Observing System Data and Information System (EOSDIS) Worldview application provides the capability to interactively browse over 700 global, full-resolution satellite imagery layers and then download the underlying data.
