SpaceX Successfully Launches Bangabandhu Satellite-1

But late this afternoon, Elon Musk's rocket company successfully launched and landed a Block 5 Falcon 9, the newest, most powerful, and most important version of SpaceX's flagship rocket. "I expect fate does not punish me for all these words, but that's unequivocally the aim. And I believe our most conservative consumers would agree with that".

This April 2 liftoff, which sent SpaceX's robotic Dragon cargo capsule toward the International Space Station (ISS) on a resupply run for NASA, used a "Block 4" Falcon 9 booster whose maiden flight occurred in August 2017.

"Standing down today due to a standard ground system auto abort at T-1 min. Rocket and payload are in good health-teams are working towards tomorrow's backup launch opportunity at 4:14 p.m. EDT, or 20:14 UTC".

SpaceX tracked the cause to liquid oxygen at the top phase tank which has trapped between the COPV overwrap and lining and sparked either from friction or alternative mechanics.

Twitter update hides tweets posted by trolls
Twitter announced Tuesday that it will implement new changes aimed at downplaying the visibility of " trolls " on its platform. Twitter is turning to a new tactic in the company's long-running battle against internet trolls: hiding their posts from view.

By maintaining the Falcon 9 layout inactive, SpaceX can devote additional time and effort to its Large Falcon Rocket and Starlink satellite constellation.

" This is without a doubt the most sophisticated pressure vessel ever established by mankind", Musk stated. "It is nuts. I have personally gone across the layout; I can not count how many occasions". The leading engineering minds at SpaceX have actually struggled over this ... "I think we are in a good situation".

Musk said that the COPVs finally have a burst pressure "over double what they're in fact packed to on the mat". Musk also said that after minor modifications Block 5 can be run up to a hundred times.

"The word "block" is a bit odd. We kind of embraced it in the Russians", he explained.

Musk said the each of the nine Merlin engines used to power the Falcon 9's first stage now have an 8 percent increase in thrust at sea level to 190,000 pounds-force. The only vacuum-optimized Merlin engine Falcon 9's second point includes a 5% push growth to 220,000 pounds-force, " he explained. Take the most recent launch of a "flight-proven" Falcon 9 first stage. All this will allow the first stage booster to fly at least 10 times without refurbishment and up to 100 total flights in its lifespan with refurbishment. Ultimately, Musk hopes to have 30 to 50 Block 5 rockets in SpaceX's fleet, capable of running hundreds of missions per year. We tried to summarize all of these lessons learned into a booster that then is able to fly and be recovered and fly again multiple times without a lot of refurbishment.

With some fix, a Block 5 first stage ought to have the ability to release 100 times, Musk stated. Falcon 9 Block 5 is created to be capable of 10 or more flights with very limited refurbishment as SpaceX continues to strive for rapid reusability and extremely high reliability. It's likewise developed for much easier production.

Musk said the Falcon 9's octaweb construction, used to encourage all nine first phase engines and supply compartmentalization if one or more neglects, is now much more powerful. The octaweb is made with bolted instead of welded aluminum and has greater thermal protection to prevent melting, he said. Placed between the first and second stages of the rocket, which are painted white, the jet-black carbon fiber interstage harkens back to SpaceX's first rocket, the Falcon 1. The Falcon 9 formerly utilized aluminum fins for guiding the Falcon 9 first stage back to Earth, however SpaceX altered those on the Block 3 to titanium after the aluminum fins ignited throughout reentry.
