Everything after clearing the tower was icing on the cake
星艦從2019年3月開始到今天，flight test是第10次，一步一個腳印。
今天的試飛也是第一次將第一級Super Heavy（超重型推進器）與第二級 Starship（星艦）連接後試飛。
高度已經到達分離位置，分離沒有成功。數據拿到後，就可以調整和改進了。
Starship achieved lift-off and cleared the tower, however, during an unsuccessful separation of the Starship 24 and SuperHeavy Booster 7 stages, which required the rocket to spin to reorient itself, the spacecraft entered an uncontrolled spin. SpaceX then engaged the onboard flight termination system resulting in a commanded destruction of the vehicle at T+ 3:59.
This was the first flight where Starship and Super Heavy flew stacked.
摘錄了兩段今天的直播視頻，目前為止的各種試飛，每一步都是前進。。。

List of SpaceX Starship flight tests

Flight |
Date and time (UTC) |
Vehicle | Launch site[b] | Flight apogee | Duration |
|---|---|---|---|---|---|
| - | 3 April 2019 | Starhopper | Launch site, Boca Chica, Texas | <0.3 m (1 ft) | ~3 seconds |
| The first firing of Starhopper and the first tethered hop (according to Musk[46][47]). The burn was a few seconds in duration and the vehicle was tethered to the ground. The vehicle might have lifted off the ground, but only to a very small height, and it was not possible to see the lift off in public video recordings of the test.[47][48] | |||||
| - | 5 April 2019 | Starhopper | Launch site, Boca Chica, Texas | 1 m (3.3 ft) | ~5 seconds |
| Tethered hop which hit tether limits. Used a single Raptor SN2 engine.[1] | |||||
| 1 | 25 July 2019[49] | Starhopper | Launch site, Boca Chica, Texas | 20 m (65.6 ft)[2] | ~22 seconds |
| First free (untethered) flight test. Single Raptor engine, SN6. | |||||
| 2 | 27 August 2019 22:00[3][50] | Starhopper | Launch site, Boca Chica, Texas | 150 m (492 ft)[3] | ~1 minute[51] |
| Single Raptor engine, SN6. Starhopper was retired after this launch and used as a water tank at the production site.[3][52][53] | |||||
| 3 | 4 August 2020 23:57[54][55] | Starship SN5 | Suborbital Pad A, Boca Chica, Texas | 150 m (492 ft)[54] | ~45 seconds |
| Used a single Raptor engine, SN27.[56] Second 150-meter hop, and first hop of a full Starship prototype.[4] | |||||
| 4 | 3 September 2020 17:47[57] | Starship SN6 | Suborbital Pad A, Boca Chica, Texas | 150 m (492 ft)[58] | ~45 seconds |
| Used a single Raptor engine, SN29. Third 150-meter hop, and second hop of a full Starship prototype.[57] | |||||
| 5 | 9 December 2020[59] 22:45 | Starship SN8 | Suborbital Pad A, Boca Chica, Texas | 12.5 km (41,000 ft)[60] | 6 minutes, 42 seconds |
| Three Raptor engines, SN30, SN36, and SN42.[61] The vehicle successfully launched, ascended, performed the skydive descent maneuver, relit the engines fueled by the header tanks, and steered to the landing pad.[60] The flip maneuver from horizontal descent to vertical was successful. However, a sudden pressure loss in the methane header tank caused by the flip maneuver reduced fuel supply and thrust, resulting in a hard landing and destruction of SN8.[60] | |||||
| 6 | 2 February 2021[62] 20:25 | Starship SN9 | Suborbital Pad B, Boca Chica, Texas | 10 km (32,800 ft)[63][62][64] | 6 minutes, 26 seconds[64] |
| Three Raptor engines, including SN45 and SN49.[64][65][66][67] A Raptor failed to start due to a problem with its oxygen-rich preburner,[citation needed] causing SN9 to over-rotate and hit the landing pad. The vehicle was destroyed by the impact forces and explosion. | |||||
| 7 | 3 March 2021[68][69] 23:15 | Starship SN10 | Suborbital Pad A, Boca Chica, Texas | 10 km (32,800 ft)[70] | 6 minutes, 24 seconds[71][c] |
| SN10 experienced a non-destructive hard landing with a slight lean after the landing and a fire near the base of the rocket,[74] and then exploded eight minutes after landing.[undue weight? ][70] SN10 did not deaccelerate enough, resulting in a hard landing damaging some legs and crushing part of the skirt. The cause was probably due to partial helium ingestion from the fuel header tank.[72] | |||||
| 8 | 30 March 2021 13:00[75] | Starship SN11 | Suborbital Pad B, Boca Chica, Texas | 10 km (32,800 ft)[76] | ~6 minutes[75] |
| SN11 launched in heavy fog, and had engine issues during ascent (according to Elon Musk).[77] Telemetry was lost at T+5:49, shortly after one engine appeared to be ignited for the landing burn and at an estimated altitude of around 600 meters.[78] Debris were then seen falling from the sky, indicating that the vehicle had exploded just above the landing site.[79] Elon Musk stated that a "relatively small" methane leak caused a fire on one of the Raptor engines which damaged it, causing hard start attempting landing burn and destruction of SN11.[80] | |||||
| 9 | 5 May 2021 22:24[81] | Starship SN15 | Suborbital Pad A, Boca Chica, Texas | 10 km (32,800 ft)[82] | 5 minutes, 59 seconds |
| SN15 was a new iteration of prototype Starship with many upgrades over previous vehicles.[83] SN15 launched in overcast weather and achieved a soft landing, with a small fire starting near the base shortly after landing. The post-flight fire was out within 20 minutes, and SN15 was retired by the end of the month.[84][85] | |||||
| 10 | 20 April 2023 00:33 | Starship S24/B7 | Orbital Pad, Boca Chica, Texas | 39 km (127,953ft)[86] | 4 minutes |
| Starship achieved lift-off and cleared the tower, however, during an unsuccessful separation of the Starship 24 and SuperHeavy Booster 7 stages, which required the rocket to spin to reorient itself, the spacecraft entered an uncontrolled spin. SpaceX then engaged the onboard flight termination system resulting in a commanded destruction of the vehicle at T+ 3:59. This was the first flight where Starship and Super Heavy flew stacked. | |||||
