跟进：NASA邀全球公众参与旅行者1号一光日活动，11月19日举行喷气推进实验室座谈
美国国家航空航天局（NASA）11月10日发布通告，邀请媒体和全球公众参与旅行者1号抵达一光日的纪念活动。旅行者1号11月18日（周三）将抵达距地球一光日的位置，届时距地球逾160亿英里（约259亿公里），是距地球最远的人造物体，来自地球的光需要24小时才能到达探测器。
第一场活动在11月17日（周二）日落后举行。NASA 邀请全世界的人们参与名为「Shine Bright for Voyager's Light-Day」的活动，在日落后向夜空发出光信号，共同形成一道象征性的环绕地球的金色光带。NASA 已建好一个网页，手机和平板电脑打开后可以自动以摩尔斯电码闪出旅行者的呼号 VGR。NASA 鼓励参与者拍下自己的光信号照片或视频，在社交平台上标注 NASA 官方账号分享。
第二场活动在11月19日（周四）中午12时（美东时间，太平洋时间上午9时）举行，地点在南加州 Pasadena 的 NASA 喷气推进实验室（JPL）von Kármán 礼堂。届时，任务团队成员与 NASA 负责人将与主持人对谈，介绍旅行者1号和2号的现状、这对探测器在星际空间持续收集的独特科学数据，以及在如此遥远的距离上维持探测器运行的挑战。对谈后设有媒体和观众问答，现场还将预映一部计划在2027年任务50周年之际推出的 NASA+ 旅行者纪录片。
出席座谈的包括 NASA 科学任务理事会副局长 Nicky Fox、喷气推进实验室首席科学家 Jonathan Lunine、旅行者项目经理 Suzanne Dodd、旅行者任务经理 Kareem Badaruddin 和旅行者项目副科学家 Jamie Rankin。想到现场参加的美国媒体须在11月16日前报名，在线参加的媒体须在活动开始前两小时报名。
旅行者1号和2号于1977年发射升空。旅行者1号2012年进入星际空间，旅行者2号沿另一条轨道于2018年进入星际空间，两艘探测器至今仍在传回日球层之外环境的数据。两艘探测器由喷气推进实验室建造和运行，该实验室由加州理工学院为 NASA 管理，NASA 深空网络负责与探测器通信。

Follow-Up: NASA Invites Public to Join Voyager 1 One-Light-Day Activities, With JPL Discussion Set for November 19
NASA invited the media and the public worldwide to join activities marking Voyager 1's arrival at one light-day from Earth, the agency announced on November 10. On Wednesday, November 18, Voyager 1 will have traveled one light-day from Earth, more than 16 billion miles (25.9 billion kilometers). It is the most distant human-made object, and light from Earth takes 24 hours to reach the spacecraft.
The first event takes place after sunset on Tuesday, November 17. NASA invites the world to participate in Shine Bright for Voyager's Light-Day by creating a symbolic wave of golden light encircling the planet after sunset. NASA has created a website that enables smartphones and tablets to flash VGR, Voyager's call sign, in Morse code. Everyone is encouraged to capture photos or videos of their light-day signal and share them on social platforms, tagging NASA.
The second event is on Thursday, November 19 at 12 p.m. EST (9 a.m. PST), at the von Kármán Auditorium of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Southern California. Mission members and NASA leadership will join a moderated discussion about the status of Voyager 1 and 2, the unique science the twin probes continue to gather in interstellar space, and the challenges of keeping the spacecraft operating over such vast distances. A question-and-answer session with media and other audience members will follow, along with a preview of an upcoming NASA+ Voyager documentary planned for release in 2027 for the mission's 50th anniversary.
Participants will include Nicky Fox, associate administrator of the Science Mission Directorate; Jonathan Lunine, chief scientist at JPL and professor of planetary science at Caltech; Suzanne Dodd, Voyager project manager; Kareem Badaruddin, Voyager mission manager; and Jamie Rankin, Voyager deputy project scientist. U.S. media interested in attending in person must RSVP by Monday, November 16, and media interested in participating virtually must RSVP no later than two hours before the event.
Voyager 1 and Voyager 2 were launched in 1977. Voyager 1 entered interstellar space in 2012, and Voyager 2 followed a different trajectory into interstellar space in 2018. Both spacecraft continue to provide observations of the environment beyond the heliosphere. JPL, which is managed by Caltech in Pasadena, built and operates the Voyager spacecraft, and NASA's Deep Space Network enables communication with the distant probes.
