SpaceX breaks reusable rocket launch record
SpaceX breaks its own record, after successfully completing a 16th mission with a reusable rocket. The company launches 22 Starlink satellites aboard the Falcon 9 rocket from the Space Force Station in Cape Canaveral, Florida. It is the 16th launch and landing for the B1058 Falcon 9 rocket booster. SpaceX says it hopes the booster can be used a further four times before finally being scrapped. There are now more than 4,000 active Starlink satellites in orbit around Earth, delivering high-speed internet to users. After the satellites are deployed, Musk writes on Twitter:
Looks like we can increase Raptor thrust by ~20 per cent to reach 9,000 tons (20 million lbs) of force at sea level… And deliver over 200 tons of payload to a useful orbit with full and rapid reusability. Fifty rockets flying every three days on average enables over a megaton of payload to orbit per year – enough to build a self-sustaining city on Mars.
200th Falcon 9 booster landing
In a rideshare mission called Transporter-8, SpaceX launches a Falcon 9 rocket containing 72 small satellites from California’s Vandenberg Space Force Base to orbit and lands the returning booster, eight minutes later, back on Earth, marking the 200th booster landing in SpaceX’s history. This is the ninth launch and landing for this particular booster. The rocket’s upper stage continued hauling aloft the 72 payloads, which included “cubesats, microsats, a re-entry capsule and orbital transfer vehicles carrying spacecraft to be deployed at a later time.” The satellites deployed from the Falcon 9’s upper stage, separate over a 24-minute span, beginning an hour after liftoff. Transporter-8 was SpaceX’s second mission in about 14 hours, the eighth small-satellite “rideshare” mission launched by SpaceX, and its third such flight of 2023.

SpaceX launches 81st Starlink mission, lands booster at sea
SpaceX successfully launches a Falcon 9 rocket, carrying 56 Starlink spacecraft, from Cape Canaveral Space Force Station in Florida, returning it to Earth less than nine minutes later, landing on the SpaceX drone ship, Just Read the Instructions, in the Atlantic Ocean. This was the 11th launch and landing for this Falcon 9 first stage booster, while Starlink Group 5-9 marks the 81st operation Starlink mission, boosting the total number of Starlink satellites launched to more than 4,400.

Starship explodes four minutes into second test attempt
After being delayed from April 18, SpaceX makes a second attempt at launching Starship. After a short countdown hold at 40 seconds the spacecraft launches and clears the tower. Four minutes into the flight, at a height of 34km, the vehicle explodes, after the second stage fails to separate. Musk congratulates the team:
Congrats @SpaceX team on an exciting test launch of Starship! Learned a lot for next test launch in a few months.

Starship launch scrubbed
The first Starship launch is scrubbed, ten minutes before launch, due to a pressurant valve being frozen. The countdown continues as a ‘wet dress rehearsal’, to T minus 40 seconds. Another launch attempt may happen in the next 48 hours.
A pressurant valve appears to be frozen, so unless it starts operating soon, no launch today

Musk ‘not saying’ Starship will get to orbit
SpaceX will debut its Starship vehicle in a month or so, but the chances of its first-ever orbital mission being a success are apparently only about 50%.
I’m not saying it will get to orbit, but I am guaranteeing excitement. So, won’t be boring!…So I think we’ve got, hopefully, about an 80% chance of reaching orbit this year. It’ll probably take us a couple more years to achieve full and rapid reusability.
According to Musk, Starship will be the most powerful rocket to ever fly, featuring about 2.5 times more thrust at liftoff than NASA’s Saturn V. SpaceX hopes that, among other things, Starship will get people and cargo to the moon and Mars. It is designed to be fully and rapidly reusable, which Musk considers the most important breakthrough for making Mars colonization and other ambitious exploration feats feasible.
Falcon 9 launches 52 Starlink satellites to orbit
SpaceX launches 52 Starlink satellites to orbit, on a Falcon 9 rocket. The launch was SpaceX’s 43rd orbital mission this year. Viewers close by the launchpad witnessed Falcon 9’s first stage falling back to Earth for a soft landing atop the SpaceX droneship, A Shortfall of Gravitas, which was stationed in the Atlantic Ocean. The company has already sent nearly 3,400 Starlinks into space and has a plan to bring thousands more aloft.
