Starliner was also being held back for an electrical wiring issue.

Meanwhile in Baikonur, the Progress MS-24 expects to be launched later this month - delivering cargo to the ISS.
I'm a bit confused on this - there was a show-stopper for Russian use of Baikonur half a year ago that seems to have been quietly resolved.

As far as I know this only affected the plans of a future Soyuz-5 rocket, which is not expected to fly this year anyway:

Luna 25 is planned to launch in a bit over a day. This will be Russia's first mission to the Moon or (including the Soviet Union) its first since Luna 24 in 1976.
Due to its unusual trajectory, Russia evacuates a town where the booster could fall down.

Edit: Successful launch.

Chandrayaan-3 has reached a low lunar orbit (~150 km). It is planned to land on August 23.

Luna 25 is planned to land on August 21.

In the first half of 2023, a total of 560 tonnes of payload have been launched to Earth orbit or beyond. Out of that 447 tonnes or 80% were launched by SpaceX, 55 tonnes (10%) by China, 31 tonnes (5.5%) by Russia and the other 5% by the rest of the world.
SpaceX launched 4 times as much as everyone else combined. Data from BryceTech

Luna 25 crashed into the Moon.

Chandrayaan-3 will attempt a landing on Wednesday or so.
Edit: Wednesday landing confirmed. Night to Wednesday for the US.

These notices don't mean much and they might keep issuing them just in case.

Japan's H-II launch of an x-ray telescope (XRISM, to low Earth orbit) and a Moon lander (SLIM) was delayed due to bad weather (livestream). We can expect another attempt soon.

 

[mfb]

SpaceX has already broken its 2022 record of 61 launches in a year, and this year has four months left.

Starship has been stacked.

Crew-6 has landed back on Earth. SpaceX has completed the original contract, started the first extension with Crew-7 and also completed three private missions before Boeing has made its crewed flight test.

Galactic Energy has launched another Ceres-1 rocket, the first launch from a sea platform. 9 flights, 9 successes, and this was the fourth flight since mid July - they are ramping up the launch rate while keeping a flawless track record.

Firefly has launched its Alpha rocket for the third time. The first flight failed, the second one reached a lower than planned orbit, the third flight was a full success. This demonstrated Firefly's ability to launch on short notice for the US Space Force - 27 hours for the final payload integration and launch preparation. The launch was visible in large parts of California.

The Block 5 variant of Falcon 9 (the only one still active) has launched 199 times so far, 199 full mission successes. The next flight is planned to launch in a few hours.
Edit: Success. 200 flights with a flawless track record.

Russia launched Soyuz MS-24 with Oleg Kononenko on board. He is expected to break the record for the longest total time in space (currently 878 days) in early February and might stay in space for a whole year, becoming the first person to spend over 1000 days in space.

I read elsewhere that they actually had the rocket ready within the 24-hour requirement set by the Space Force. At that point, it was a matter of waiting for the desired orbit's next available launch window, which was several hours later.

Rocket Lab's Electron had a launch failure. The video feed cut off shortly after stage separation and based on the telemetry the velocity kept decreasing, so it looks like something got destroyed when the second stage ignited.

This was the 40th orbital launch of the rocket. The first one failed due to a problem with a ground station, the 13th, 20th and now 40th failed due to problems with the upper stage.

The launch was called "We Will Never Desert You" ...

OSIRIS-REx is expected to return its asteroid samples on Sunday. It's the third asteroid sample return mission after Hayabusa and Hayabusa 2 and has by far the largest samples collected from beyond the Moon (hundreds of grams).
Might be visible somewhere in Utah or surrounding states, I don't know its reentry trajectory. 8:42 MDT.

The source asteroid, Bennu, has a small chance to hit Earth between 2178 and 2290 - if that chance doesn't drop to zero in the future it could become an interesting target for a deflection mission.

 

[mfb]

NASA livestream for OSIRIS-REx, starting in a bit under 9 hours.

SpaceX has broken its booster reflight record, flying a booster for the 17th time on Wednesday - and then flying another booster for the 17th time just an hour ago.

 

[mfb]

~4 minutes until it hits the atmosphere. It will enter the atmosphere somewhere over San Francisco and fly to a landing site near Salt Lake City. Could be visible from a very large area along that path.

 

[berkeman]

Nice, thanks @mfb -- touchdown.

 

[berkeman]

They just reported that the main parachute deployed at 20,000 feet instead of the 5,000 feet initially reported. That explains why it took so long to descend from 5,000 feet by parachute. I was wondering what was going on. Deploying a bit early is not a problem, IMO.

 

[Tom.G]

The earlier than expected chute deployment was blamed on correct operation!

A deceleration sensor was used to trigger drogue chute deployment. It sensed the programmed deceleration earlier than expected -- so it opened the chute.

Shortly after landing, an annoucer explained the above and at least implied everything operated correctly -- just unexpectedly.

Doubtful that we will get anything further.

9 days and one hour until the launch of Psyche, a mission to the very unusual asteroid of the same name.
The spacecraft will also be the first test of laser communication over interplanetary distances, and it will be the first interplanetary mission with a real payload for Falcon Heavy. The next one is scheduled for October 2024 (Europa Clipper).

It's a day launch but both side boosters return to the launch site, so it should be interesting to watch from close to the launch site.

Countdown

Edit: Delayed by a few days to work on some issue with the spacecraft, looks resolved.

Blue Origin gets a new CEO. Bob Smith left, apparently "encouraged" to leave. They hired Dave Limp coming from Amazon, and the internet is already full of jokes.

 

[mfb]

They had a first look at the OSIRIS-REX samples. In addition to the main sample container they also got a lot of stuff scattered around it, which seems to be interesting on its own.

6 days 15 hours until the launch of Psyche.

Russia has determined why Luna-25 crashed. A command to turn on the inertial guidance unit didn't have enough priority to be sent ahead of an engine firing, so the software thought the engine burn wouldn't change the motion of the spacecraft. As a result it fired 50% longer than planned, enough to make it crash. Scott Manley made a more detailed video

12 hours until the launch of two test satellites for the Kuiper constellation on an Atlas V (18:00 UTC, this post is 5:45 UTC). Probably its lightest payload to low Earth orbit ever, it could easily launch 20 of them. Amazon wanted to launch these as secondary payload on Vulcan but then that rocket kept getting delayed. They need to start launching regularly soon and of course you want to test the satellites before, so now a big rocket ends up flying two small test satellites.

Vega will return to flight in a bit under 24 hours. It had a failed launch in December last year.

Musk talked about Starship at the International Astronautical Congress but it was mostly stuff that was known already. Starlink satellites are expected to be the first real payloads and he thinks they can start launching them within a year. While they keep working on Starship they are still increasing the Falcon 9 launch rate.
They have two Falcon launch pads in Florida. At the moment only LC-39A can fly crewed missions and Falcon Heavy, but SLC-40 has been optimized to launch in rapid succession. 5 flights in July, 5 in August, 6 in September. Maybe they want to get the other pad to the same rate. That would allow ~150 launches in a year (~60*2 in Florida and ~25 in California).

Looks like a Russian ISS module has a leak. Again.

Nauka had an air leak in July 2021.
Soyuz MS-22 had a coolant leak in December 2022.
Progress MS-21 had a coolant leak in February 2023.
Now apparently Nauka has another leak, probably coolant.

Under 3 days until the launch of Psyche. The weather forecast is very windy.
Edit: Delayed by 1 day due to bad weather.

 

[mfb]

Psyche launch in 1 hour 15 minutes. Forecast says 85% chance of good weather.

I'll never tire of seeing the SpaceX boosters returning and landing cleanly.

 

[mfb]

Successful launch and they have acquired a signal from the spacecraft. Shot from the payload separation, spacecraft in the center and second stage of Falcon Heavy to the right:

Successful booster landings, too. Over 150 successful landings in a row now.

Boeing openly admits it can't be competitive in spaceflight programs.
They want to do only cost+ contracts, i.e. contracts where the company is incentivized to waste as much money as they can because that will increase the guaranteed profit.

India has successfully tested the in-flight abort system of its crew capsule Gaganyaan. An orbital flight is planned in 2024 and a crewed orbital flight could follow in 2025, making India the fourth country to send people to orbit (and space) with its own hardware.

After a year of accident investigation, Blue Origin plans the next flight of New Shepard on October 31. Spooky unofficial livestream.

Rocket Lab expects Electron to return to flight within this year, recovering from the failure in September, but does not have a launch date yet. Likely November.

 

[mfb]

Looks like Shenzhou 16 had a pretty rough landing. The crew seems to be fine, but you don't want to tumble like that.

Jared Isaacman and Tim Dodd discussing astronaut training, Starship and more

Some news items: Polaris Dawn with the first commercial/private spacewalk is still planned for the first quarter of 2024. They'll also launch and land in the spacewalk suit because carrying two sets would take up too much space.

The second Polaris mission will certainly have a spacewalk, too. A repair and reboost of Hubble seems to be the default plan, if NASA doesn't want it they'll do something else.

Edit: Rocket Lab finished its accident investigation, a bad insulation combined with unusual conditions led to an electric arc.
