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.
太平洋時間上午 11 點 36 分,SpaceX 在加州范登堡太空部隊基地的東 4 號航太發射場成功發射了兩顆下一代地球觀測衛星。
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.
這兩顆衛星由 Maxar Technologies 建造,是目前計劃替換舊觀測衛星的六顆衛星中的第一顆。它們在升空後大約 13 到 16 分鐘被部署到太陽同步軌道,後來當獵鷹 9 號第二級返回地面站範圍時,SpaceX 證實了這一點。
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.
隨著 Maxar 繼續取代舊一代衛星,SpaceX 也將在未來幾個月發射接下來的四顆衛星。四架飛機將從佛羅裡達州發射。這兩個發射場使 Maxar 能夠進入多種軌道類型並更好地覆蓋全球。
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 以執行本次任務的獵鷹9 號火箭再次達到發射20 次的目標,這次是使用助推器1061。燃和著陸從發射台。
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 現已安全發射8 名太空人(機組人員1 和2)、國際太空站補給任務、NASA X 射線空間天文台、2 次電信任務、2 次運輸車共乘任務、以色列ISI EROS C-3 偵察衛星、韓國425偵察衛星和 9 次星鏈任務。
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.
第二級還配備了“粗短噴嘴”,當 SpaceX 不需要全尺寸真空噴嘴的全部性能時,偶爾會使用它。
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.
與目前的慣例一樣,SpaceX 也使用了經過飛行驗證的整流罩,其中一個整流罩已經進行了第 16 次飛行。對於這次任務來說,這是相當了不起的,因為有效載荷具有高度敏感的光學器件,而 SpaceX 現在能夠翻新這些整流罩,並確保它們在大氣層飛行期間不會污染所保護的有效載荷。
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.
這並不是今天唯一的一次飛行,因為 SpaceX 目前正計劃發射 23 Starlink,這將是 Booster 1067 的第 19 次發射。該發射目前計劃不早於美國東部時間晚上 9:49。
