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 galaxy’s spiral arms, along with lacy reddish-brown dust clouds and pink star-forming regions. As fascinating as the galaxy appears at visible wavelengths, some of NGC 5643’s most interesting features are invisible to the human eye. Ultraviolet and X-ray images and spectra of NGC 5643 show that the galaxy hosts an active galactic nucleus: an especially bright galactic core powered by a feasting supermassive black hole. When a supermassive black hole ensnares gas from its surroundings, the gas collects in a disk...

The addition of a reflective coating on the spacecraft's large deployable antenna delayed the launch of NISAR. Credit: NASA WASHINGTON — A joint Earth science mission between NASA and its Indian counterpart is now scheduled to launch as soon as next March after being delayed to repair its main radar antenna.In a presentation at the annual meeting of the American Geophysical Union here Dec. 11, Gerald Bawden, program scientist for the NASA-ISRO Synthetic Aperture Radar (NISAR) mission at NASA Headquarters, said the spacecraft is now scheduled to launch from India in a window that opens in late March. NISAR was previously scheduled to launch in the spring of this year, but NASA announced in March that it would delay the launch to make repairs to the spacecraft’s 12-meter deployable reflector used by its main radar instrument.

Ingenuity helicopter’s flying days cut short by featureless Martian terrain

It appears the bland Martian surface triggered a chain of events that left NASA's Ingenuity helicopter permanently grounded on the red planet. The helicopter's flying career came to an abrupt end earlier this year when Flight 72 was cut short, and communications were briefly lost. After re-establishing contact, it soon became clear Ingenuity would not be flying again – the rotor blades were damaged, and one was entirely detached. At the time, the prevailing theory was that the flight ended when Ingenuity's downward-facing camera could not pick out features on the surface. According to the NASA Jet Propulsion Laboratory (JPL), this is still the most likely scenario for what started a chain of events that left the helicopter crippled. Performing an air crash investigation from hundreds of millions of kilometers away is tricky. It's...
