Watch CNN's Acosta & Ex-Acting DHS Sec Wolf Go Head-to-Head Over Legitimacy of Biden's 2020 Win_我的网站

A |      8 月 26 日消息，在两名宇航员的努力下，国际空间站（ISS）外部两套天地通信天线中的一套重新恢复工作，宇航员如今再次可以通过这套设备与地面进行通信。当地时间 8 月 25 日，两名宇航员在一次太空行走中完成了故障天线组件的更换工作。

B | 注意到，美国国家航空航天局（NASA）宇航员阿尼尔 · 梅农和欧洲航天局（ESA）宇航员索菲 · 阿德诺此前曾在 8 月 18 日的一次太空行走中拆除故障天线。本周二，两人将备用天线安装到原位，并将损坏的天线组件从临时存放位置转移至空间站桁架结构上更为固定的长期存放位置。    Former acting Homeland Security Secretary Chad Wolf and CNN presenter Jim Acosta got into bit of a verbal duel over Wolf's allegations of election fraud in the 2020 presidential election.,Wolf's Sunday appearance on CNN saw Acosta prod the Trump-era official to comment on whether President Joe Biden legitimately won the 2020 election; however, within moments, the discussion turned tense.,.@Acosta doesn't allow Chad Wolf to get away with not answering when asked if Joe Biden won the 2020 election. At one point Acosta told Wolf that he sounded like a conspiracy theorist. pic.twitter.com/YJCTIkyNgq— Sarah Reese Jones (@PoliticusSarah) August 21, 2022,Wolf raised the issue of voter fraud and irregularities, prompting Acosta's question of: "Who won the 2020 election?",The former DHS secretary responded: "Obviously Joe Biden is president." Unsatisfied with the answer, Acosta pressed, asking: "Do you believe that he won that election fair and square?",However much the CNN host pressed him, Wolf did not budge.,Wolf declared that Biden was president, but ultimately added that he lacked sufficient proof to declare Biden's election genuine. The Trump-era official proceeded to reference the use of drop boxes in Wisconsin to support his allegations of fraud, stating that polling regularly reveals Americans' lack of faith in election security.,"There are a number of irregularities, illegalities and fraud," Wolf said before Acosta interjected with: "Not enough to alter the outcome of the election.",Wolf was criticized by Acosta for subverting democracy and guiding Americans down a "path of lies," among other things.,As the segment came to a close, Acosta stated: "It sounds like you've watched one too many conspiracy theories on the 2020 election.",The discourse around possible violations in the 2020 presidential election has not subsided, thanks in large part to Trump's repeated assertions that Biden won due to multiple violations at the polling stations.,This rhetoric is supported by the former president's sympathizers, especially amid the Biden administration's failures to deal with crises, such as record inflation and the disruption of supply chains.。在此次太空行走中，梅农位于加拿大机械臂 Canadarm2 的末端，阿德诺则沿着空间站外部的扶手移动，与梅农会合。两名远征 75 任务乘组成员首先从空间站外部储存位置取出一套备用天地通信天线（SGANT）。随后，梅农携带备用天线被机械臂转移至 Z-1 桁架位置，并在那里完成天线安装，同时将其接入国际空间站的电力和数据系统。

C | 完成新天线安装后，梅农和阿德诺又取回了此前一次太空行走中临时存放在 Z-1 桁架上的故障天线。随后，位于机械臂末端的梅农将其转移至空间站桁架右舷一侧的外部储存平台 3 号（ESP-3）。此次更换工作源于这套天地通信天线自去年 11 月起出现故障。该设备已经无法继续跟踪 NASA 的数据中继卫星，因此失去使用能力。此后，国际空间站一直依靠另一套天线传输语音和关键数据，而此次维修完成后，整个通信系统重新恢复了冗余备份能力。此次太空行走于美国东部时间星期二上午 8 时 27 分开始，并在 6 个半小时后的下午 2 时 57 分结束，整个过程恰好持续 6.5 小时。这是为支持国际空间站组装、维护和升级而进行的第 283 次舱外活动。此次任务也是梅农个人的第 3 次太空行走，使其累计舱外活动时间达到 19 小时 20 分钟。

D | 对于阿德诺来说，这是她第 2 次进入太空真空环境开展舱外活动。她的累计太空行走时间因此增至 12 小时 53 分钟。此前，她成为首位进行太空行走的法国女性宇航员，也是历史上第 5 位完成太空行走的法国公民。此次任务还是国际空间站今年进行的第 6 次太空行走、远征 75 任务期间的第 2 次舱外活动，同时也是国际空间站第 98 次使用美国舱外机动装置（EMU）宇航服完成的太空行走。
