About 3% of Starlinks Have Failed So Far

SpaceX has drawn plenty of praise and criticism with the creation of Starlink, a constellation that will one-day provide broadband internet access to the entire world. To date, the company has launched over 800 satellites and (as of this summer) is producing them at a rate of about 120 a month. There are even plans to have a constellation of 42,000 satellites in orbit before the decade is out.

However, there have been some problems along the way as well. Aside from the usual concerns about light pollution and Radio Frequency Interference (RFI), there is also the rate of failure these satellites have experienced. Specifically, about 3% of its satellites have proven to be unresponsive and are no longer maneuvering in orbit – which could prove hazardous to other satellites and spacecraft in orbit.

Elon Musk Shares a View of Starship With Three Raptor Engines Installed

SpaceX has been very busy lately with the development of its Starship prototypes. Based on recent activity at its Boca Chica facility, and recent images provided by Musk himself, it looks like they are about ready to make their biggest leap yet. Yesterday, on Oct. 14th, Musk announced that the eighth prototype of the Starship (SN8) has received the three Raptor engines it will use to make its planned 15.25 km (50,000 ft).

Starman Just Made his Closest Approach to Mars

On February 6th, 2018, SpaceX successfully launched its Falcon Heavy rocket, the most powerful launch vehicle in their rocket family, and in service today. Not only was this a major milestone for SpaceX, it was also the biggest public relations coup ever orchestrated by Musk. For this launch, Musk decided that the payload would be his cherry Tesla Roadster with a SpaceX spacesuit (affectionately named “Starman”) at the wheel.

Those who watched the live footage of the event (or caught the compilation video released shortly after) are not likely to forget Starman and the Roadster orbiting Earth as David Bowie played in the background. At the time, it was also anticipated that Starman and the Roadster would eventually make a close pass of Mars. Two years after launch, Starman finally accomplished a flyby of the Red Planet!

Another Starship Test Tank is Pushed to the Limit and Explodes

They say that failure can be the greatest teacher of all, and it’s easy to see why. Those who learn from their mistakes become informed as to what can go wrong, and will develop the necessary strategies to avoid making the same mistake in the future. This philosophy is also at the core of SpaceX rapid-prototyping process, where full-scale models of the Starship and its components are tested to the point of failure.

At Boca Chica, SpaceX ground crews continue to follow this process in order to get the Starship ready for orbital testing. The latest piece of hardware that was tested to failure was the SN7.1 Test Tank, which was pressurized until it exploded. This test took place a week ago (on the evening of September 23rd) shortly after the SN5 and SN6 prototypes both completed a 150 m (~500 ft) hop test.

The SpaceX Starship Could be Making its Biggest Hop Yet (and a Belly-Flop) Next Month!

SpaceX is getting closer to the day when it will be able to make good on its promise of conducting regular missions to orbit, the Moon, and to Mars. At the heart of all this is the progress they are making with their Starship and Super Heavy launch system. In recent weeks, Musk’s commercial space company conducted two successful 150 m (500 ft) hop tests with the SN5 and SN6 prototypes at the Boca Chica launch facility in southern Texas.

Based on the latest announcements to come out of SpaceX, it appears that this recent string of successes has emboldened Musk and his company. Previously, Musk indicated that he was planning on making several more small hop tests and that the SN8 would attempt a 20 km (12 mi) flight sometime next year. More recent indications, however, suggest that Musk wants to conduct this high-altitude test before the end of October.

SpaceX’s Starship Prototype Nails Another Hop Test! Bring on Orbital Flights!

SpaceX has done it again! Earlier today (Thurs. Sept. 3rd), the company completed a second hop test with a Starship prototype. This time, it was the sixth iteration (SN6) that successfully made the 150-meter (~500 foot) flight at their launch facility near Boca Chica, Texas. This latest test has further validated the Starship design and the Raptor engine, two systems which Musk hopes will someday take humans to the Moon, to Mars, and beyond!

SpaceX is Going to Hop Starship Again This Weekend

With a first successful hop test under their belts using a full-scale prototype, SpaceX is pressing ahead with the testing of the Starship. Tomorrow (on Sunday, August 30th), SpaceX will be attempting to make a second 150 meter (500 ft) hop test, this time with their sixth Starship prototype (SN6). It’s all part of a very busy weekend for SpaceX, with no less than three launches planned.

Astronauts Come Back to Earth on August 2nd, Completing the Full Crew Dragon Test

On Monday, March 30, 2020 at a SpaceX processing facility on Cape Canaveral Air Force Station in Florida, SpaceX successfully completed a fully integrated test of critical crew flight hardware ahead of Crew Dragon’s second demonstration mission to the International Space Station for NASA's Commercial Crew Program; the first flight test with astronauts onboard the spacecraft. NASA astronauts Bob Behnken and Doug Hurley participated in the test, which included flight suit leak checks, spacecraft sound verification, display panel and cargo bin inspections, seat hardware rotations, and more.

On May 30th, SpaceX and NASA made history when a Crew Dragon spacecraft carrying two astronauts (Robert Behnken and Douglas Hurley) launched atop a Falcon 9 rocket and rendezvoused with the International Space Station (ISS). With this one flight, NASA and SpaceX demonstrated that the US once again has domestic launch capability, something they have not enjoyed since the retirement of the Space Shuttle in 2011.

In one week, Sunday, August 2nd, Robert and Douglas will be returning to Earth using the same Crew Dragon spacecraft (named Endeavour) that took them to the ISS. This is the most crucial part of Demo-2 flight, where the spacecraft is tasked with bringing the astronauts home, safe and sound. As you can imagine, there are a lot of people who are understandably nervous, not the least of which is SpaceX founder Elon Musk.

SpaceX Finally Catches Both Halves of a Falcon 9 Fairing

On July 20th, SpaceX launched a South Korean military communications satellite (ANASIS-II) using the same Falcon 9 that delivered a pair of astronauts to the International Space Station (ISS) back in May. And in another interesting development, this mission was the first time that SpaceX managed to not only retrieve the first stage booster at sea but also retrieved both halves of the payload fairing.

Will We See a Starship Test This Week?

As we speak, engineers at SpaceX’s Boca Chica test facility are busy getting the fifth Starship prototype (SN5) ready. Having recently passed the crucial cryogenic load test, and with the installation of its SN27 Raptor engine, the ground crews are now gearing up for a static fire test. Assuming the SN5 doesn’t explode in a massive fireball (as the SN4 did), it will be ready to make the first hop test of a full-scale Starship prototype.
