What time is SpaceX's 3rd Starship launch test on today?
SpaceX is hoping to launch its first Starship test of 2024 as early as Thursday (March 14) in what it hopes will be a historic orbital flight of the world's biggest rocket, and if you need to know when to watch it online, you're in the right place.
SpaceX is targeting March 14 for the launch from its Starbase facility near Boca Chica Beach in South Texas. The announced on X that Starship has a 110-minute window on Thursday, with liftoff targeted for 9:25 a.m. EDT (1325 GMT), about 30 minutes in.
The company will webcast the launch attempt, beginning at 8:52 a.m. EDT (1252 GMT). You can watch the livestream here at Space.com, courtesy of SpaceX. There is a 70% chance of good weather at launch time, SpaceX has said.
SpaceX's Starship vehicle and its Super Heavy booster are the world's tallest and most powerful rocket. When stacked together, they stand 400 feet tall (122 meters), with the first stage powered by 33 Raptor engines, while the Starship upper stage carries six Raptors.
SpaceX has designed the Starship launch system to be fully reusable and hopes to use it for deep-space exploration, heavy-lift launches and space tourism. The company has already sold two private trips around the moon on Starship, with NASA picking Starship to land its Artemis 3 astronauts on the moon by 2026. But first, SpaceX has to prove its Starship can reach orbit, let alone the moon, and has failed to do so in two previous attempts in April and November of 2023. Here's what we know about Flight 3, SpaceX's third Starship test launch.
Today, SpaceX is targeting March 14 at 9:25 a.m. EDT (8:25 a.m. CDT/1325 GMT) for its third Starship test flight. That's about 30 minutes into a 110-minute launch window that opens at 8 a.m. EDT. The company will air a livestream of the liftoff, beginning at 8:52 a.m. EDT (1252 GMT ) on March 14.
SpaceX's first Starship test flight launched on April 20, 2023 but never reached space. It was intentionally destroyed after its two stages failed to separate. A second test flight on Nov. 18 did manage to reach space, but not its target altitude. The Super Heavy booster separated successfully from the Starship upper stage, but both vehicles eventually were destroyed shortly after stage separation.
"Each of these flight tests continue to be just that: a test," SpaceX wrote in a Flight 3 mission description. "They aren't occurring in a lab or on a test stand, but are putting flight hardware in a flight environment to maximize learning."

Artemis: n
表示" [希神]阿耳忒弥斯（狩猎女神和月神）"，如：The whole army was moved to behold the beautiful maiden standing in serene dignity before the altar of Artemis. 看到这位美丽的姑娘宁静端庄地站在阿耳忒弥斯祭坛前，整个军队被感动了。
中文简要说明：
更新：星舰火箭完成分离，试射初步成功，星舰重返大气层准备降落印度洋时爆炸。
第一级超重型助推火箭在降落的最后阶段失去讯号，可能没有站稳而落入海中。不过，这一次的测试，并没有要回收超重型助推火箭，所以算是成功.
马斯克在推特上表示，「星舰达到轨道速度！恭喜SpaceX团队！！」
SpaceX第3度挑战星舰-超重型火箭(Starship -Heavy)的测试，希望这款世界上最强力的火箭完成历史性的轨道飞行。
SpaceX将从德南部博卡奇卡海滩(Boca Chica Beach)的太空基地进行发射。该公司在 X平台(也就是推特) 上宣布，预计将于美东时间上午9时25分(台北时间21点25分)升空。
SpaceX 表示，发射时出现好天气的可能性为 70%。
在SpaceX的官网，该公司表示，上一次的飞行测试，虽然失败了，但实现了许多重大里程碑，并为继续快速开发火箭提供了宝贵的数据。马斯克表示，每一次飞行测试都是将飞行硬件放入飞行环境中，以最大效率提高学习效果。
第三次飞行的目标，希望能够实现全引擎的点燃，二级火箭(星舰)的脱离与点火发射、打开和关闭星舰的载荷门，在太空中重新点燃猛禽发动机，以及星舰的可控再返回地球。如果走到这一步，星舰的目标是在印度洋溅落。
