15 Billion Miles Away, NASA’s Voyager 1 Breaks Its Silence The shutdown and the turn on appears to have been triggered by spacecraft’s fault protection system, which automatically manages onboard issues. This system conserves power by disabling non-essential systems if spacecraft’s power supply is overstretched. However, it could take days to weeks for the team to pinpoint what exactly activated the fault protection system.

Troubleshooting and Command Response
NASA’s Jet Propulsion Laboratory (JPL) in Southern California manages communications with Voyager 1 via the Deep Space Network. When the JPL team sends instructions, Voyager 1 responds by transmitting engineering data, which helps the team assess its reaction to the command. This back-and-forth takes around two days—nearly 23 hours for command to travel over 15 bil miles (24 bil kilometers) to Voyager 1 & another 23 hrs for data to return to Earth.

On October 16, the flight team sent a command to turn on one of the spacecraft’s heaters. While Voyager 1 should have had ample power to operate the heater, the command triggered the fault protection system. The team learned of the issue when the Deep Space Network couldn’t detect Voyager 1’s signal on October 18.

Communication Challenges and Solutions
The spacecraft typically communicates with Earth using what’s called an X-band radio transmitter, named for the specific frequency it uses. The flight team correctly hypothesized that the fault protection system had lowered the rate at which the transmitter was sending back data. This mode requires less power from the spacecraft, but it also changes the X-band signal that the Deep Space Network needs to listen for. Engineers found the signal later that day, and Voyager 1 otherwise seemed to be in a stable state as the team began to investigate what had happened.

Then, on October 19, communication appeared to stop entirely. The flight team suspected that Voyager 1’s fault protection system was triggered twice more and that it turned off the X-band transmitter and switched to a second radio transmitter called the S-band. While the S-band uses less power, Voyager 1 had not used it to communicate with Earth since 1981. It uses a different frequency than the X-band transmitters signal is significantly fainter. The flight team was not certain the S-band could be detected at Earth due to the spacecraft’s distance, but engineers with the Deep Space Network were able to find it.

Mission Continuity and Challenges
Rather than risk turning the X-band back on before determining what triggered the fault protection system, the team sent a command on Oct. 22 to confirm the S-band transmitter is working. The team is now working to gather information that will help them figure out what happened and return Voyager 1 to normal operations.

Voyagers 1 & 2 have been flying for more than 47 years, are only two spacecraft to operate in interstellar space. Their advanced age has meant an increase in frequency & complexity of technical issues, new challenges for the mission engineering team.

What Florida's gov just did is a big solution for SpaceX & Elon after Cali's gov...As California shuts its doors on SpaceX's ambitious launch plans, where can they find the next promised land for their space missions?. Honestly, nowhere could be more ideal than Florida’s coast!

Yeah, what Florida’s gov just did is a major solution for SpaceX after facing pushback from California's gov over increasing launch counts.

Let’s find out on today’s episode of Alpha Tech:
The relationship between SpaceX and the California Coastal Commission is becoming increasingly tense. 

Cause lies in Commission's opposition to a plan by SpaceX & U.S. Space Force to increase rocket launches at Vandenberg Air Force Base to up to 50 per year. In response, Elon Musk has filed a lawsuit against Commission, arguing their decision was based on unacceptable reason: his political comments on the X platform.

This move appears to be based on personal bias, lacking consideration for the country’s broader interests. Even California Governor Gavin Newsom—who rarely aligns with Musk remarked, “I’m with Elon,” at a campaign event for Harris  and Walz in North Carolina.

Moreover, this week, Elon Musk and SpaceX received further attention from Washington?.

A NASA safety panel warned SpaceX to focus on crew safety for its commercial trips to the International Space Station (ISS) after four astronauts were recently hospitalized. apparent operating safely requires significant attention to detail as hardware ages, the pace of operations increases,” Rominger is quoted as saying. “Both NASA and SpaceX need to maintain focus on safe Crew Dragon operations and not take any ‘normal’ operations for granted.”

NASA’s SpaceX Crew-8 recently returned from ISS, riding on board a Dragon spacecraft, the spacecraft’s splashdown off coast of Florida on last Friday, all four astronauts were transported to a hospital & 1 crew was kept for an overnight stay. NASA did not release further information about why crew was hospitalized or whether it was related to the Dragon splashdown. SpaceX’s trusty Falcon 9 rocket has suffered few missteps this year. Falcon 9 rocket launched Crew-9 mission on Sept 28, transporting NASA astronaut Nick Hague & Russian cosmonaut Aleksandr Gorbunov to ISS aboard Dragon crew capsule. On its way down to land in the ocean, the rocket’s upper stage experienced an off-nominal deorbit burn that caused it to miss its targeted splashdown zone....

Both Voyager 1 and its twin, Voyager 2, have been bopping along for nearly a half-century, far beyond their original life expectancy. Launched in 1977, the pair was originally intended to study Jupiter and Saturn, their moons, and Saturn's rings. For the two-planet journey, they were built to last just five years.

After their initial success, engineers doubled their objectives to include two more giant planets, Uranus and Neptune. Between the two spacecraft, they've explored four planets, 48 moons, and a host of planetary magnetic fields and rings.
In August 2012, Voyager 1 made history as it entered interstellar space, the region between stars, filled with material ejected by other stars that died millions of years ago. Voyager 1 and 2 are the only spacecraft ever to operate outside of the heliosphere, the region of space affected by the sun's constant flow of material.

Voyager 1 launched from Earth in 1977 and is the farthest human-made object in space. Voyager 1 is speeding away from the solar system at over 38,000 mph and is the farthest human-made object from Earth. It is so far away that it takes 23 hours for a command to reach the spacecraft, and another 23 hours for mission control to hear back from it.

NASA has previously said the Voyagers generate about 4 fewer watts of power annually, limiting the number of systems the spacecraft can use. Flight controllers have occasionally turned off equipment to conserve power. The goal is to keep the two running beyond 2025, according to the agency.

NASA has announced an updated plan to continue New Horizons’ mission of exploration of the outer solar system. Beginning in fiscal year 2025, New Horizons will focus on gathering unique heliophysics data, can be readily obtained during an extended, low-activity mode of operations.

While the science community is not currently aware of any reachable Kuiper Belt object, this new path allows for the possibility of using the spacecraft for a future close flyby of such an object, should one be identified. It also will enable the spacecraft to preserve fuel and reduce operational complexity while a search is conducted for a compelling flyby candidate.

“The New Horizons mission has a unique position in our solar system to answer important questions about our heliosphere and provide extraordinary opportunities for multidisciplinary science for NASA and the scientific community,” said Nicola Fox, associate administrator for NASA’s Science Mission Directorate in Washington. “The agency decided that it was best to extend operations for New Horizons until spacecraft exits Kuiper Belt, which is expected in 2028 through 2029.”

New, extended mission will be primarily funded by NASA’s Planetary Science Division and jointly managed by NASA’s Heliophysics and Planetary Science Divisions.
