SpaceX launched its 20th Falcon 9 rocket of the year on Wednesday, and the booster lofting the Transporter-2 mission completed yet another successful flight to orbit.

This launch continues to cement the progress SpaceX has made toward the viable reuse of rocket first stages. This rocket core, named B1060, for booster number 1060, had previously flown into space seven times. Its first launch was a GPS III satellite mission for the US Space Force on June 30, 2020. With Wednesday's flight, the rocket has now flown eight missions in a calendar year.

With the Falcon 9, by contrast, SpaceX has been able to learn from dozens of booster re-launches, and this has allowed the company to streamline the refurbishment needed between missions. "Work needed between flights is less & less, as shown by shortening time between reflights," SpaceX founder Elon Musk said on Twitter Wednesday.

The rapid reuse of the Falcon 9 rocket also makes for some stellar visuals. The Transporter-2 mission launched Wednesday carried several dozen small satellites, but the overall payload mass was low enough that the booster could carry enough fuel to return to a landing site near the launch site. This means our photographer, Trevor Mahlmann, was able to get excellent photographs of both the launch and landing.

Moreover, Mahlmann was able to compare what B1060 looked like a year ago, when he captured images of the GPS III launch, to what the booster looks like today. Sooty the rocket, we would say, has never looked better.

Elon Musk calls rocket launch regulations 'broken' after aircraft delays SpaceX launch

CNBC 03 July, 2021 - 09:21am

SpaceX was seconds away from launching its 20th mission of this year Tuesday when the countdown was halted due to an aircraft entering the launch range, delaying the mission by at least a day.

Elon Musk took to Twitter to voice his frustration about the delay, reiterating prior criticisms he has made about regulations around the business of launching rockets.

"An aircraft entered the 'keep out zone', which is unreasonably gigantic," Musk wrote in a tweet.

"There is simply no way that humanity can become a spacefaring civilization without major regulatory reform. The current regulatory system is broken," he added.

Musk has ratcheted up his criticism of launch regulations this year, with SpaceX firing off Falcon 9 rockets at a blistering pace – with launches going up an average of every nine days – and also flying multiple development tests of its Starship prototype rockets. After a Starship test was delayed in January, Musk similarly criticized the Federal Aviation Administration for how it handles launch regulations.

"Unlike its aircraft division, which is fine, the FAA space division has a fundamentally broken regulatory structure," Musk wrote then. "Their rules are meant for a handful of expendable launches per year from a few government facilities. Under those rules, humanity will never get to Mars."

The FAA has internally pushed back on SpaceX, after the company violated its launch license with the authorized test flight of Starship prototype SN8 in December. Since then, the FAA says SpaceX has "modified their procedures effectively" and earlier this month testified before Congress about efforts to streamline launch regulations and rules.

Although he's publicly criticized regulators, Musk has also stated that "99.9% of the time, I agree with regulators!"

"On rare occasions, we disagree. This is almost always due to new technologies that past regulations didn't anticipate," Musk said in April.

SpaceX Had To Call Off A Launch Only A Few Seconds Before Liftoff

Jalopnik 03 July, 2021 - 09:21am

The Falcon 9 rocket, called Transporter-2, was supposed to take 88 different satellites — some for the U.S. government, others for private companies — into orbit, in what is a line of SpaceX’s business. Except now the launch attempt has been delayed until Wednesday after the aircraft mishap Tuesday.

The action starts around the 14:00 of the video below, when, at around t-58 seconds you can hear cheers as the flight computer starts up. But then someone can be heard on the radio saying that the range is a “no-go,” to which the SpaceX host seems unaware. With less than 20 seconds left, the same person on the radio repeats “no-go” and the coundown clock is held.

The SpaceX host eventually returns to the screen and says that they are done for the day and will try again tomorrow.

The host seems a bit sheepish, probably because having Elon Musk as your CEO means that everyone who works for SpaceX must project the same cheerful overconfidence. Still, this all strikes me as minor given that rocketry is unbelievably complex and what tripped up SpaceX today was not their technology but something out of its control.

It is true that there is simply no way that humanity can become a spacefaring civilization if rocket launches face minor delays, as minor delays were the downfall of all the spacefaring civilizations before us.

SpaceX launches Transporter 2 mission with EnduroSat's Spartan - SatellitePro ME

SatelliteProME.com 03 July, 2021 - 09:21am

This is the first of nine upcoming Shared Missions of EnduroSat, that will streamline the deployment of commercial sensors, and verify next-gen technologies in Space. Spartan, is carrying seven payloads. It is demonstrating the capability of the software-defined architecture to provide customers easy access to space data.

This was the second dedicated rideshare flight organised by SpaceX and carried 88 spacecraft to an approximately 525 km altitude sun-synchronous orbit (SSO).

Raycho Raychev, Founder & CEO of EnduroSat, said: “We are thrilled to see the innovations and the incredible work, that our partners and customers will do in orbit, thanks to Spartan. We believe that EnduroSat’s Shared Satellite Service is a paradigm shift that eliminates the entire complexity of getting sensors to orbit. Give us what you want to fly and in a few months’ time you are operating your sensor in space and downlinking data to the ground.”

SatellitePro ME addresses all aspects of the satellite industry, covering the key vertical markets including Oil & Gas, Broadcast, Telco, Maritime, Government & Military, Aviation and Enterprise. Experts discuss the paramount issues within the industry, from interference and regulation to standards and market breakthroughs.
