Hubble Images a Grand Spiral
This NASA/ESA Hubble Space Telescope image features the glorious spiral galaxy NGC 5643, which is located roughly 40 million light-years away in the constellation Lupus, the Wolf. NGC 5643 is a grand design spiral, which refers to the galaxy’s symmetrical form with two large, winding spiral arms that are clearly visible. Bright-blue stars define the […]
Amendment 82: A.48 Commercial Satellite Data Earth Science and Applications Final Text and Due Dates Released
A.48 Commercial Satellite Data Earth Science Research and Applications (CESRA) was established to identify, evaluate, and acquire data from commercial sources that support NASA’s Earth science research and application goals. NASA’s Earth Science Division (ESD) recognizes the potential impact commercial small-satellite constellations may have in encouraging/enabling efficient approaches to advancing Earth System Science and applications […]
Sols 4391-4392: Rounding the Bend
Earth planning date: Wednesday, Dec. 11, 2024 For planning today, we have a beautiful view of the northern tip of Texoli, as seen in the image foreground. Unfortunately, the rocks that make the view so pretty also made it unsafe to unstow the arm for contact science. Instead we are doing a lot of imaging […]
Sols 4389-4390: A Wealth of Ripples, Nodules and Veins
Earth planning date: Monday, Dec. 9, 2024 We are continuing to edge our way around the large “Texoli” butte. Much of the bedrock we have been traversing recently looks pretty similar — paler-colored laminated bedrock — but today’s workspace had some interesting features, as did the “drive direction” image, which focuses on the future drive […]
NASA Study: Crops, Forests Responding to Changing Rainfall Patterns
Earth’s rainy days are changing: They’re becoming less frequent, but more intense. Vegetation is responding.
Found: First Actively Forming Galaxy as Lightweight as Young Milky Way
For the first time, NASA’s James Webb Space Telescope has detected and “weighed” a galaxy that not only existed around 600 million years after the big bang, but is also similar to what our Milky Way galaxy’s mass might have been at the same stage of development. Other galaxies Webb has detected at this time […]
Hubble Life Extension Initiatives
Initiative Description/Benefit Status Pointing and Control 2-Gyro Science Mode Attitude control using 2 gyros + another sensor (MSS, FHSTs, FGS) to achieve high quality science with only 2 gyros. Implemented (2005-2009) 1-Gyro Science Mode Attitude control with 1 gyro + combination of MSS, CSS, FHSTs, FGS, and B-field model. Performance equivalent to 2-gyro […]
Looking Out for ‘Lookout Hill’
At Pico Turquino, a bedrock mesa on the Jezero crater rim, the science and engineering teams planned proximity science on Percy’s 30th abrasion patch, Rio Chiquito. SCAM and ZCAM characterized the rock near the abrasion, while SHERLOC and PIXL instruments were deployed for proximity science. The data from Rio Chiquito will help characterize the Pico […]
JunoCam
Citizen Science Home Citizen Science JunoCam Projects Highlights Publications NASA Citizen Scientists Science Activation Resources JunoCam NASA’s Juno satellite is in orbit around Jupiter, the largest planet in our Solar System. This satellite carries the JunoCam, a visible-light camera controlled by scientists on Earth. JunoCam is also the name of the collaboration among scientists […]
Discovery Alert: A Planet with a ‘Tail’
The Planet WASP-69 b The Discovery The exoplanet WASP-69 b has a “tail,” leaving a trail of gas in its wake. Key Takeaway WASP-69 b is slowly losing its atmosphere as light hydrogen and helium particles in the planet’s outer atmosphere escape the planet over time. But those gas particles don’t escape evenly around the […]
