On the afternoon of May 5th, 2021, at 05:24 PM local time, SpaceX made its fifth attempt at a high-altitude test flight and soft landing with a Starship prototype. Given the outcomes of the previous test, this event had many people on the edge of their seats. In all four attempts, the prototypes managed to reach their maximum altitude and pull off the bellyflop maneuver, but then exploded during landing (or shortly thereafter).
Would the fifteenth iteration of the Starship prototype (SN15) succeed where the others had failed? As of 05:30 P.M. local time (06:30 P.M. EDT; 03:30 P.M. PDT), the answer to that question is, “WITH GUSTO!” On their fifth attempt, the SN15 not only managed to reach its target altitude of 10 km (6.2 mi) and pull off the belly-flop and controlled descent, it also stuck the landing and suffered no mishaps afterward.
In other words, COMPLETE SUCCESS!

Project Artemis, NASA’s long-awaited plan for sending astronauts to the Moon for the first time since the Apollo Era, has taken many steps forward. Aside from the development of the Space Launch System (SLS), the Orion spacecraft, and the elements that will make up the Lunar Gateway, NASA recently awarded SpaceX with the contract to build the Human Landing System (HLS) that will transport astronauts to the lunar surface.
However, this decision didn’t sit well with the other two companies NASA was also considering. These included Blue Origin, the commercial space company founded by Amazon founder and former CEO Jeff Bezos, and Alabama-based aerospace company Dynetics. After protests were filed by both companies, NASA decided to issue a stop-work order on the HLS award to SpaceX while it reviews the complaints.

Thanks to Musk’s preference for sharing his ideas directly with the public, SpaceX is inundated with all kinds of proposals from citizen scientists and space-exploration enthusiasts – some of which are practical and some outlandish. This latest proposal definitely straddles these two categories! In an animation shared via Twitter, 3D digital artist Nick Henning offered an alternative vision for a SpaceX tower that could “catch” the Super Heavy.

Space exploration sure is hard, huh? Luckily, it’s an iterative process, where engineers test and test and test again to work out all the bugs in advance. At least, that’s what we remind ourselves when the prototype goes “kaboom!” Earlier today, the SN11 joins its predecessors by being the fourth Starship prototype to conduct a successful flight test and then explode while attempting to make a landing (or shortly thereafter).

Update: Yesterday (March 9th), Elon Musk shared the reason for the explosion via Twitter. According to Musk, the problem originated with the one Raptor engine used to slow the SN10 down before landing.
“SN10 engine was low on thrust due (probably) to partial helium ingestion from fuel header tank,” he tweeted. “Impact of 10m/s crushed legs & part of skirt. Multiple fixes in work for SN11.“
On March 3rd, 2021, SpaceX conducted a third high-altitude flight test with one of their Starship prototypes (SN10). This time around, the prototype managed to achieve an apogee of 10 km (6.2 mi), a controlled descent relying on nothing but its aerodynamic surfaces (the “belly-flop”), and even managed to land successfully. However, a few minutes after it stuck the landing, the SN10 exploded on the landing pad.
Whereas the SN8 and SN9 explosions were attributed to problems that took place during engine reignition, the cause of the SN10 explosion was not as clear. Thankfully, astrophysicist and Youtube personality Scott Manley (Twitter handle @DJSnM) has offered his take on what might have caused it. Using SpaceX’s footage of the SN10 flight test, he suggests that a slightly-harder-than-intended landing and a fuel tank rupture were responsible.

They say, “third time’s the charm.” This was largely the case today as SpaceX made their third attempt at a high altitude flight test at their launch facility in Boca Chica, Texas. Like the previous two attempts, this flight saw a Starship prototype (SN10) with three Raptor engines fly to an altitude of 10 km (6.2 mi), conduct a “belly-flop” descent maneuver, and then return to the launch facility.
As with the previous high-altitude tests, the SN10 successfully launched, reached its apogee, and validated the control fins and aerodynamic surfaces. But unlike the previous tests, the SN10 was able to slow down enough and keep itself upright so it could make a soft landing. While the prototype exploded a few minutes after landing (apparently from a methane leak) the flight was a complete success!

Another day, another round of testing (and yes, another explosion). Today, on Tuesday, Feb. 2nd, 2021, flight teams at SpaceX’s launch facility near Boca Chica, Texas, conducted a high-altitude test flight with a Starship prototype. Similar to the previous test in December, the SN9 was powered by three Raptor engines, flew to an altitude of 10 km (6.2 mi), then attempted another “belly flop” to test out its fins and aerodynamic surfaces.
As always, the event was broadcast via live stream by SpaceX, NASASpaceFlight, LabPadre, and several other observers. Like the SN8 test flight, SpaceX’s coverage provided multiple vantage points (landing pad, engine compartment, fuselage, aerial drone, etc.) The flight commenced at 2:25:15 P.M. CST (04:25:15 EST; 12:25:15 PST) when the Starship ignited its three engines and began its ascent.

Over the years, Elon Musk has been rather open about how he (and the company he founded) plan to make space more accessible and allow humanity to become an “interplanetary species.” A key element to this plan is the Starship and Super-Heavy launch system, which will allow for regular trips to the Moon as well as the eventual creation of the first human colony on Mars.
Another key part of Musk’s plan is the creation of spaceports at sea that will allow for greater flexibility with launches and landings. To that end, SpaceX recently acquired two former oil drilling rigs off the coast of Texas. These spaceports have been dubbed Phobos and Deimos (after Mars’ two satellites) and are currently undergoing modifications to conduct Starship launches in the near future.

SpaceX is getting closer and closer to realizing the design for its Starship and Super Heavy launch system. Once complete, it will be the world’s first fully-reusable launch system and will facilitate trips to Low Earth Orbit (LEO), the Moon, and Mars. Construction began on the system’s booster element (Super Heavy) this past summer and, according to a recent tweet by Musk, will be “caught” by its launch tower.

To commemorate their greatest accomplishment to date with the Starship, SpaceX has released a recap video of the SN8 high-altitude flight. This was the 12.5 km hop test that took place on December 9th, 2020, which saw the SN8 prototype ascend to an altitude of 12.5 km (7.8 mi), conduct a “belly-flop” maneuver, and return to the launch pad. While it didn’t quite stick the landing, the test was a major milestone in the development of the Starship.
