NASA Powers Down Voyager 1 Instrument

🛸 Voyager 1 powers down to survive

🌌 Black hole jets dance with power

☀️ NASA watches a comet's final moments

JPL (Jet Propulsion Laboratory) engineers commanded Voyager 1 to shut down its Low-energy Charged Particles experiment, conserving power on humanity's first interstellar explorer now over 15 billion miles from Earth.

The spacecraft's radioisotope thermoelectric generator loses approximately 4 watts of power annually; commands take 23 hours to reach Voyager 1, with the LECP shutdown process requiring an additional three hours and fifteen minutes.

Engineers expect this shutdown provides roughly one year of operational margin before implementing "the Big Bang" power-saving fix, according to Voyager mission manager Kareem Badaruddin.

CIRA (Curtin Institute of Radio Astronomy) researchers led by Dr. Steve Prabu used Earth-spanning radio telescope arrays to measure jet power from Cygnus X-1, the first confirmed black hole system.

The team determined jets travel at half the speed of light, approximately 150,000 kilometers per second, with power output equivalent to 10,000 Suns by observing stellar wind deflection patterns.

According to Professor James Miller-Jones, this measurement confirms that 10 percent of infalling matter energy escapes via jets, validating assumptions used in large-scale Universe simulations.

ESA's (European Space Agency) Mars Express spacecraft documented volcanic ash spreading across Utopia Planitia, comparing current imagery with NASA Viking orbiter observations from 1976 showing significant expansion.

The HRSC (High Resolution Stereo Camera) captured a 15-kilometer crater with ejecta blanket surrounded by mafic mineral-rich volcanic deposits containing olivine and pyroxene giving the distinctive dark coloration.

Scientists at Freie Universität Berlin suggest Martian winds redistributed ash over five decades, demonstrating ongoing surface changes within this ancient 3,300-kilometer-diameter basin once hosting water.

Caltech graduate student Matthew Belyakov led JWST (James Webb Space Telescope) observations of 3I/ATLAS, only the third detected interstellar object, as it passed within 1.5 AU of the Sun.

JWST's MIRI instrument detected methane emissions at mid-infrared wavelengths increasing as solar heating shed the comet's billion-year cosmic ray-irradiated outer surface, revealing pristine interior composition.

According to Belyakov, this kilometer-wide planetesimal offers unprecedented insight into distant planetary system chemistry, with final JWST observations planned this spring before it passes Jupiter.

NASA's heliophysics fleet including SOHO (Solar and Heliospheric Observatory), STEREO, and PUNCH missions captured comet C/2026 A1 MAPS disintegrating during its April 4 close solar approach.

SOHO's LASCO coronagraph observed the Kreutz sungrazing comet disintegrate several hours before closest approach, while STEREO tracked from 54.5 degrees off the Sun-Earth line revealing orbital dynamics.

According to principal investigator Karl Battams of the U.S. Naval Research Laboratory, such observations reveal cometary structure and early solar system formation conditions when these objects originated.
