Reference excerpt

Starship flight test 13 was the thirteenth flight test of the SpaceX Starship launch system, using Booster 20 and Ship 40. During the initial launch attempt on July 16, 2026, the vehicle's flight software triggered an automatic abort at T−0 just prior to liftoff after six Raptor engines had problems with their oxidizer turbo-pumps and failed to meet flight speeds, protecting both the vehicle and the launch pad from damage. After another scrub due to weather conditions, the third launch attempt on July 24 was successful and became the first Starship flight to deploy operational satellites, 20 Starlink satellites were deployed in suborbit and made contact with the Starlink constellation. Booster 20's ocean landing burn failed when only ten of 13 Raptor engines relit, with subsequent shutdowns causing destruction on impact.

Background

Federal clearance for flight Following Starship flight test 12, a mishap investigation report was completed to secure flight clearance. The Federal Aviation Administration (FAA) concluded its review on July 13, clearing the path for subsequent Starship launches.

Vehicle testing ahead of launch

Booster 20 Following assembly, Booster 20 (B20) was transported to the Massey's test site on June 5, 2026, where it completed a cryogenic proof test the following day. On July 10, after moving to Pad 2, the booster completed a major pre-flight milestone by executing a successful, full-duration, 33-engine static fire.

Ship 40 Stacking operations for Ship 40 (S40) concluded on March 2, 2026, with cryogenic testing completing at Massey's in early May. Following engine installation, the vehicle returned to Massey's on June 23. S40 completed a successful single-engine static fire on June 25 after a brief diagnostic run. After returning briefly to the production site for final checks, S40 was transported back to Massey's, where it fired all six engines on July 1.

Launch attempts SpaceX initially targeted Thursday, July 16, for flight 13; however, the flight was scrubbed at T-minus 0 seconds as four of the 33 Raptor engines failed to ignite. Initially, the second launch attempt was scheduled for Monday, July 20, but was later rescheduled for Thursday, July 23. The date was moved to July 24 due to Tropical Storm Bertha.

Mission profile

The flight profile built upon previous test flights. Starship flew on a controlled suborbital trajectory designed to fall just short of orbit, while the Super Heavy booster executed a flip and boostback burn before suffering multiple engine failures and splashing down hard in the Gulf of Mexico. The upper stage carried 20 next-generation Starlink satellites, six of which were equipped with advanced cameras to inspect S40 in space, mirroring the Space Shuttle's rendezvous pitch maneuver (RPM). Because the flight was intentionally suborbital, the satellites reentered the atmosphere about 20 minutes after deployment. To further demonstrate its advancing capabilities, the ship performed an in-space Raptor relight before executing a targeted splashdown and landing flip maneuver in the Indian Ocean. The ship splashed down and remained intact and operational after tipping over, a first for the vehicle, allowing a drone to inspect the heat shield and engines.

Flight timeline The timeline below reflects the initial aborted July 16 attempt, as well as the actual launch on July 24.

Recovery Elon Musk confirmed that SpaceX would attempt recovery efforts of Ship 40 on July 28. The SpaceX recovery vessel Go Australis remained near Ship 40 from a few days after splashdown, later joined by tugs Normand Ranger and Skimmer Tide half a day later. Musk stated on X that recovery of Ship 40 was looking doubtful on August 7. Normand Ranger and Go Australis towed Ship 40 to waters off Christmas Island on August 18, with the Australian Space Agency confirming the Australian government were aiding in recovery operations. SpaceX stated on X that engineers will conduct additional analysis on site before attempting to return Ship 40 to Starbase, Texas. An exclusion zone was established around Ship 40 and Normand Ranger at Christmas Island. On August 23, semi-submersible heavy-lift ship Forte arrived at Christmas Island, to transport Ship 40 back to Starbase. Ship 40 was loaded onto Forte on August 26 after engineers collected heatshield samples and data from the ship.

Aftermath Flight Test 13 resulted in a successful test of Ship 40, from stage separation to splash down, completing verification for a future orbital flight with testing of an in-space Starship engine relight. Shortly after flight test 13 Elon Musk announced that flight test 14 would include catching the Starship with the "Mechazilla" launch tower which would require the Starship to have entered orbit first.

Worked examples

Example 1 — a first encounter with Starship flight test 13

Start with the simplest possible case. Write down what Starship flight test 13 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Starship flight test 13 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Starship flight test 13 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Starship flight test 13

In research: Starship flight test 13 appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Starship flight test 13 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Starship flight test 13 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2026 in Texas, 2026 in spaceflight, Cameron County, Texas, so understanding it makes those chapters shorter.
In everyday life: Look for Starship flight test 13 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
