NASA is repairing its connection to Voyager 1
NASA has been making significant progress in fixing its link to Voyager 1, the iconic spacecraft that has been journeying through the outer Solar System since its launch in 1977. Communication with Voyager 1 had recently become challenging due to garbled data transmissions, but engineers at NASA have identified the root cause of the issue to be the Flight Data System (FDS) onboard the spacecraft.
On March 1st, the team at NASA issued a ‘poke’ command to Voyager 1 in an attempt to troubleshoot the problem with the FDS. This command initiated a process of varying parameters and sequences to identify any corrupt sections of the code. Subsequently, on March 3rd, the team detected unusual activity from a specific portion of the FDS, which prompted further investigation.
To their surprise, one of the Deep Space Network engineers at NASA managed to decode a signal from Voyager 1 that contained a complete and readable dump of the entire FDS memory. This dump included program code, variables, scientific data, and engineering data that could potentially lead the team to the cause of the communication issue.
Due to the vast distance of over 24 billion km that Voyager 1 is from Earth, there is a significant delay in communication, with signals taking over 22 hours to travel each way. Despite this challenge, the NASA engineers began decoding the data on March 7th and soon realized that they had a complete data dump from the FDS.
The team is now meticulously analyzing the data to identify and isolate any errors in the code that could be causing the communication problem. Once a solution is found, it will take some time to implement, but NASA is confident that they will be able to resolve the issue and reestablish communication with Voyager 1.
Voyager 1’s mission has been a remarkable journey of exploration, capturing iconic images such as the ‘pale blue dot’ of Earth from billions of kilometers away. Its golden record containing sounds and images of Earth serves as a message to any potential alien civilizations that may encounter the spacecraft.
As NASA continues its efforts to reconnect with Voyager 1, the world awaits the exciting developments that may come from this mission of discovery and exploration.

University of Wisconsin-Milwaukee and Protesters reach an agreement to dismantle encampment
Protesters at the University of Wisconsin-Milwaukee have agreed to end their pro-Palestinian encampment following an agreement reached with the school, university officials announced on Sunday. The encampment, which had been in place for two weeks, will be dismantled by Tuesday, marking the end of what was believed to be the last standing encampment at a Wisconsin college.
University officials had allowed the encampment to remain on a patch of lawn between Mitchell Hall and a busy thoroughfare on the campus’s southern boundary, opting not to involve law enforcement. This approach differed from the response at the University of Wisconsin-Madison, where police were called in to remove tents after negotiations fell through. Despite initial efforts to disband the encampment, Wisconsin-Madison eventually reached an agreement with protesters to voluntarily dismantle the camp prior to commencement ceremonies.
Chancellor Mark Mone of Wisconsin-Milwaukee stated last Wednesday that the university had exhibited “the widest possible amount of patience and restraint.” However, he also cautioned that patience was wearing thin and hinted at potential action by the school. Following discussions with the UWM Popular University for Palestine Coalition, the university agreed to advocate for a cease-fire between Israel and Hamas, condemn the destruction of schools and universities in Gaza by Israeli forces, and hold meetings with protest leaders regarding university investments.
Additionally, the university pledged to urge the Water Council, a Milwaukee organization of water technology companies, to sever connections with two Israeli government-owned entities, Mekorot and the Israel Innovation Authority. Chancellor Mone serves as the treasurer on the Water Council’s board of directors.
In return for these commitments, the protesters agreed to dismantle the encampment beginning on Sunday and completing the process by Tuesday. They also agreed not to disrupt the university’s commencement ceremonies scheduled for Sunday. In a statement, the protesters expressed their satisfaction with the agreement, stating, “After hard fought edits and careful consideration by the coalition, we determined we had obtained all possible benefits from the encampment.”
The resolution of the encampment at the University of Wisconsin-Milwaukee represents a successful outcome of negotiations between university officials and protesters. By reaching a compromise that addresses the concerns of both parties, a peaceful resolution has been achieved, allowing for the encampment to be taken down without incident.
