Given that the wing will be in a stowed config on the launch, I don't think they will go for a horiz take-off but an air-dropped test so that wing deployment and engine startup can be tested, and of course the flight transitions from a free-fall in a semi-stable condition into a fully stable glide config and then into powered flight.
I'm very keen to see this vehicle fly after so long as a (derided) mockup. Flyback boosters are the real deal for reuseables, more so than inverted candles in IMHO. The technology lends itself to bigger applications such as returning orbital spaceplanes and SSTOs.
Stupid Muskian fan-bois have always derided the idea of winged flyback boosters as having "wasted mass" but that is nonsense. I don't remember US sources ever bemoaning the fact that SRBs are heavy and hopelessly inefficient from an ISP aspect - they (correctly) point out that the mass and relative inefficiency of strap-ons doesn't matter as their job is solely to get the core to altitude. No need to get them into orbit, so just add on whatever mass and fuel they require and let 'em rip.
Krylo-SV is intended to be a stand-alone light booster, but its sized to be suitable as a strap-on for a heavy-lifter. Its a great interim step for developing a fly-back strap-on for the future modular SHLV, whatever shape or form it ends up taking.

By contrast, having a spent booster return to the surface via flight is ideal since the rocket engine life is not wasted and it is actually
feasible to use the thicker layer of the atmosphere to control the descent via gliding (with some optional power). There is no symmetry
between take off and landing. That only applies to jet flight which never goes above 42,000 feet (aside from some exotics like the U-2
and M-55) and does not exceed 900 km/hr for civilian travel.
The "inverted candle" concept is indeed stupid. Useful payload is reduced because fuel has to be saved for the return trip and the engine
life is reduced for no valid reason other than fapping by fanbois.
Good to see the Baikal concept finally getting some practical development.

The weld on the Soyuz-5 tank. The seam is made by friction welding with mixing using a Russian machine developed by the company "Sespel" together with the Institute of Strength Physics and Materials Science SB RAS
And this is a photo of the workshop where the equipment for the production of Soyuz-5 is mounted.
Video of the machine operation.

MOSCOW, December 5 - RIA Novosti. The Russian Soyuz-ST-B launch vehicle with Galileo satellites successfully launched from the Kuru cosmodrome.
The broadcast of the event was shown on the Roscosmos website .
According to the official Telegram channel of the state corporation, the rocket successfully brought the Fregat upper stage with satellites to a suborbital trajectory. It is noted that the "Fregat" has started the flight mission. The mission will last 3 hours 51 minutes.
Both birds have separated correctly and are delivered to correct orbits. Another successful mission for Russian launchers

The Yandex automatically translates documents but has a size limit of 5MB and this document is 10 times bigger than that so it wont translate the whole document in one go.
You could split it up into 10 pieces and translate each piece.

So - Maezawa on the ISS. The one who bought a ticket for Starship from Musk, but now flew to the ISS on the Russian Soyuz.

Maezawa will get more bang for his buck (yen) with Russia than he will from Musks amateur operation.
He wil also only need to spend ~6hrs in the Soyuz until docking with ISS. Murkans spend >24hrs in their capsules on-route. Time is money...

The Bezos racket is a joke. It is suborbital and the "hour" is mostly going up and down. But since it is a yanqui racket, it
is a great achievement compared to those Russian primitives.

The Virgin racket with their pissy little rocket glider is even worse. Calling it a "spacecraft" is simply a fecking insult.

MOSCOW, December 9. / TASS /. The launch of the Angara-A5 heavy launch vehicle from the Plesetsk cosmodrome is scheduled for the evening of December 23. This is stated in the message of the administration of the Kargasok district of the Tomsk region.
"It is planned to launch the Angara-A5 rocket from the Plesetsk cosmodrome (Arkhangelsk region). The launch time is December 23, 2021 at 18:00 Moscow time (reserve launch date - December 24, 2021)," the message says. posted on the district page in the social network " VKontakte ".
That should make 24 flights this year, or 25 if the Soyuz from ESA Kourou cosmodrome is included (as it should be). That will be the 3rd straight failure-free year since the aborted Soyuz MS-10 in Oct 2018

Russia launches trials of plasma thrusters for nanosatellite orbit retention
The plasma thrusters will be mounted on two satellites of Sputnix Company that will be launched into space under the Space PI program in 2022
MOSCOW, December 9. /TASS/. Russia has launched the trials of a plasma thruster for retaining the attitude of small space vehicles in orbit, the press office of Sitronics Group told TASS on Thursday.
"The staff of the plasma engine laboratory of the LaPlas Institute within the MEPhI National Research Nuclear University has launched trials jointly with representatives of the Sputnix Company (part of Sitronics Group) of Russia’s first plasma propulsion unit that can be mounted on small space vehicles," the press office noted.
The engine has been named VERA (Volume-Effective Rocket-propulsion Assembly). "The small size and weight of the thrusters that have been developed make it possible to retain a cluster of ten nanosatellites in orbit," the press office added.
With these thrusters mounted on CubeSat 3U satellites weighing no more than 4 kg, these space vehicles will be capable of retaining their orbital position or, upon the completion of their operation, lower the orbit’s altitude, cutting the time of burning up in the dense layers of the atmosphere two-or three-fold. The orbit lowering maneuver after the end of the satellite’s operation will make it possible to cut the time of space junk existence, the press office specified.
These plasma thrusters will be mounted on two satellites of Sputnix Company that will be launched into space under the Space PI program in 2022.

Guys at Plasetsk are one of main reasons launch statistics are this good, it’ll be fine

Another remark was revealed on the upper stage. We will not risk it, the technical management has decided to calmly finalize the missile system in the assembly and test building. We will leave with the launch on a reserve date, which we will inform you about additionally.
