SpaceX successfully launched two next-generation Earth observation satellites from Space Launch Complex 4 East at Vandenberg Space Force Base in California at 11:36 am PT.

太平洋时间上午 11 点 36 分，SpaceX 在加利福尼亚州范登堡太空部队基地的东 4 号航天发射场成功发射了两颗下一代地球观测卫星。

These two satellites, built by Maxar Technologies, are the first of six currently planned to replace older observation satellites. They were deployed into a Sun-synchronous orbit at around 13 and 16 minutes after lift-off, which was later confirmed by SpaceX once the Falcon 9 second stage came back into range of a ground station.

这两颗卫星由 Maxar Technologies 建造，是目前计划替换旧观测卫星的六颗卫星中的第一颗。它们在升空后大约 13 到 16 分钟被部署到太阳同步轨道，后来当猎鹰 9 号第二级返回地面站范围时，SpaceX 证实了这一点。

SpaceX will also launch the next four satellites in the coming months as Maxar continues to replace older generation satellites. The four will launch from Florida. These two launch sites give Maxar access to multiple orbit types and better coverage of the globe.

随着 Maxar 继续取代老一代卫星，SpaceX 还将在未来几个月发射接下来的四颗卫星。四架飞机将从佛罗里达州发射。这两个发射场使 Maxar 能够进入多种轨道类型并更好地覆盖全球。

SpaceX once again hit the 20-launch mark with the Falcon 9 that launched this mission, this time with Booster 1061. Due to a lightweight payload, B1061 was able to perform a boost backburn and touchdown at Landing Zone 4, a few hundred feet away from the launch pad.

SpaceX 凭借执行本次任务的猎鹰 9 号火箭再次达到发射 20 次的目标，这次是使用助推器 1061。由于有效载荷较轻，B1061 能够在几百英尺外的着陆区 4 进行助推回燃和着陆从发射台。

Booster 1061 has now safely launched 8 humans (Crew 1 & 2), an ISS resupply mission, a NASA x-ray space observatory, 2 telecommunication missions, 2 Transporter rideshare missions, an Israeli ISI EROS C-3 recon satellite, the Korea 425 recon satellite, and 9 Starlink missions.

助推器 1061 现已安全发射 8 名宇航员（机组人员 1 和 2）、国际空间站补给任务、NASA X 射线空间天文台、2 次电信任务、2 次运输车拼车任务、以色列 ISI EROS C-3 侦察卫星、韩国 425侦察卫星和 9 次星链任务。

The second stage also featured the “stubby nozzle,” which SpaceX will occasionally use when it does not need the full performance of a full-sized vacuum nozzle.

第二级还配备了“粗短喷嘴”，当 SpaceX 不需要全尺寸真空喷嘴的全部性能时，偶尔会使用它。

SpaceX, as is usual now, also used flight-proven fairings, with one of the halves flying for the 16th time. This is fairly remarkable for this mission as the payloads feature highly sensitive optics, and SpaceX is now able to refurbish these fairings and ensure they do not contaminate the payloads they protect during atmospheric flight.

与现在的惯例一样，SpaceX 也使用了经过飞行验证的整流罩，其中一个整流罩已经进行了第 16 次飞行。对于这次任务来说，这是相当了不起的，因为有效载荷具有高度敏感的光学器件，而 SpaceX 现在能够翻新这些整流罩，并确保它们在大气层飞行期间不会污染所保护的有效载荷。

This isn’t the only flight today, as SpaceX is now looking to launch 23 Starlink, which will see Booster 1067 launch for the 19th time. That launch is currently scheduled for no earlier than 9:49 pm ET.

这并不是今天唯一的一次飞行，因为 SpaceX 目前正计划发射 23 Starlink，这将是 Booster 1067 的第 19 次发射。该发射目前计划不早于美国东部时间晚上 9:49。
