At this point, SpaceX could claim to be both a rocket company and also a maritime shipping company. The company owns a fleet of drone ships for the purposes of providing their rockets with a safe place to retrograde land in the ocean without having to splash down. In the past, they actually had additional ships for fairing catching, Dragon Capsule recovery, and other support efforts. But now, the company welcomed its newest drone landing ship with an announcement by Elon Musk on Twitter. Welcome to the SpaceX: A Shortfall of Gravitas.Continue reading “
At their South Texas Launch Facility, just outside of the village of Boca Chica, SpaceX is gearing up to test the Super Heavy, the booster element of their Starship launch system. This massive reusable first stage rocket will be responsible for sending the Starship orbital vehicle to space, where it will deliver satellites to orbit, payloads and people to the Moon, and (if all goes as planned) the first human settlers to Mars.
According to a recent statement issued by SpaceX founder Musk Musk, the Starship could also be used to “chomp up debris” in Earth orbit. As usual, the statement was issued via Twitter, where Musk was once again addressing questions posted by followers and fans. The topic arose after Musk shared the latest updates about Starlink, one of a handful of satellite constellations that are bringing broadband internet services to every corner of the planet.Continue reading “According to Elon, Starship Could Chomp up Space Junk”
As usual, the SpaceX South Texas Launch Facility, located near the village of Boca Chica, is the focal point of a lot of attention. Almost two months ago, crews at the facility began working on the first true Super Heavy prototype, the launch stage of SpaceX’s Starship. After six weeks of assembly, SpaceX rolled the Super Heavy Booster 3 (B3) out of the “High Bay” (where it was assembled) and installed it onto the launch pad.Continue reading “After Just 6 Weeks of Construction, Super Heavy is Built and Ready to Move”
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!Continue reading “SpaceX’s SN15 Starship Prototype Nails It!”
Last weekend (April 24th), China celebrated its sixth “National Space Day” (aka. Aerospace Industry Achievement Exhibition) in Nanjing, an event that highlights advances China has made in space. Similar to Space Day that is held each year on the first Thursday in May (this year, it will be held on May 7th), the goal is to foster interest in space exploration and the STEMS so as to inspire the next generation of astronauts and aerospace engineers.
This year, the festivities focused on the Chang’e-5 mission (which showcased some of the lunar samples it brought back), and the name of China’s first Mars rover (Zhurong) – which will be landing on the Red Planet later this month. But another interesting snippet was a video presented by one of China’s main rocket manufacturers that showed demonstrated that they are working on a rocket similar to the Starship.Continue reading “Chinese Company Claims to be Working on a Starship-Like Rocket”
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.Continue reading “What if Starship Didn’t Do a Landing Burn at All?”
As part of the Artemis program, NASA is gearing up to send the “first woman and next man” to the Moon by 2024. Central to this is the development of the Space Launch System (SLS), the most powerful rocket since the Saturn V that took the Apollo astronauts to the Moon, and the Orion spacecraft. But after these elements transport astronauts to Lunar orbit, they will need a lander to take them to and from the surface.
For this reason, NASA contracted a number of commercial partners to develop a Human Landing System (HLS). After much consideration, NASA announced on Friday, April 16th, that they had selected SpaceX to continue developing their concept for a lunar lander. When American astronauts return to the Moon for the first time in fifty-two years, it will be a modified version of the Starship that will bring them there.Continue reading “NASA Picks SpaceX to Land Astronauts on the Moon!”
If there is one driving force in the commercial space industry it is economics. The whole concept of reusable booster rocket emphasizes the importance of getting launch costs down. SpaceX, the company leading the charge in trying to bring launch costs down, doesn’t just recover booster rockets however. It also recovers the rocket fairings that hold the payload during launch. SpaceX’s original plan was to capture the fairings as they fell back to Earth using specially equipped ships with nets to catch them before they landed in the ocean. Now, however, the company has transitioned to simply fishing fairings out of the ocean after they splash down, and that seems to be working just fine.Continue reading “SpaceX has Given up Trying to Catch Rocket Fairings. Fishing Them out of the Ocean is Fine”
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).Continue reading “Latest Starship Prototype SN11 Explodes in mid-air, Raining Debris on the Launch Site”
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.Continue reading “Fantastic Analysis of SN-10 Landing and Explosion by Scott Manley”
