NASA Successfully Tests Telemetry Signal on Agency’s First All-Electric X-plane

afrc2020-0038-11_0.jpg
Telemetry testing begins on the X-57 Maxwell, NASA’s first all-electric X-plane, as the operations crew at NASA’s Armstrong Flight Research Center records the results. Telemetry testing is a critical phase in X-57’s functional test series. In addition to confirming the ability of the X-57 aircraft to transmit speed, altitude, direction, and location to teams on the ground, telemetry testing also confirms the ability to transmit mission-critical-data, such as voltage, power consumption, and structural integrity. X-57’s goal is to help set certification standards for emerging electric aircraft markets.

In a First, NASA Measures Wind Speed on a Brown Dwarf

Not quite planets and not quite stars, brown dwarfs are cosmic in-betweeners. Learning about their atmospheres could help us understand giant planets around other stars.

PIA23684-Cool-Brown-Dwarf-MAIN-16_0.jpg
This artist's concept shows a brown dwarf, an object that is at least 13 times the mass of Jupiter but not massive enough to begin nuclear fusion in its core, which is the defining characteristic of a star. Scientist using NASA's Spitzer Space Telescope recently made the first ever direct measurement of wind on a brown dwarf.

Rethinking cosmology: Universe expansion may not be uniform

Astronomers have assumed for decades that the Universe is expanding at the same rate in all directions. A new study based on data from ESA’s XMM-Newton, NASA’s Chandra and the German-led ROSAT X-ray observatories suggests this key premise of cosmology might be wrong.
