Working in extreme heat and extreme cold might be useful in a future of climate change... if we overdo it with green house gas reductions we might end up in an ice age... looking at Venus is a window into what will happen in a runaway greenhouse situation.

The earth has been much hotter than it is now and also much colder than it is now and it survived just fine... the secret wont be being able to flick a switch to get the weather and temperature we want, but learning how to cope with the different temperature extremes without excessive energy use to do so.

Venus is more interesting to me because it is hidden and much less is known about it.... you can get a high power telescope and have a good look at Mars from earth or from space but with Venus you really do have to land to get a decent view.

Venus is just more of a challenge and I fully understand why the US wants to go with Russia...

Something that operates in the clouds in a more moderate environment could operate for much longer and perhaps provide better images from a more moderate environment.

The winds are rather strong at high altitudes and since the density is not small they will be dragging any platform without control.

The Vega program did exactly that. 2 balloons floating at 54km above the surface.

KOROLEV / Moscow region /, November 26. / TASS /. The "Prichal" junction module as part of the Progress M-UM spacecraft, launched on Wednesday from the Baikonur cosmodrome, docked at the docking port of the Nauka multipurpose laboratory module, a TASS correspondent reports from the Mission Control Center (MCC, part of Roscosmos).

The docking took place in an automatic mode under the control of specialists from the Mission Control Center (MCC, part of Roskosmos) from the Earth and cosmonauts from the ISS.

The Soyuz-2.1b launch vehicle with the spacecraft and the module was launched at 16:06 Moscow time on Wednesday. The docking was carried out according to a two-day scheme. The mass of the removed load was 8.18 tons. Astronautics historian Alexander Zheleznyakov told TASS that this is a record for the payload mass for launches to the ISS on the Soyuz-2 launch vehicle.

The new module will expand the capabilities of Russian spacecraft docking with the ISS, including the new Orel spacecraft. In total, five objects will be able to dock to it. For the first time, the Soyuz manned spacecraft is to dock at the new nodal module on March 18 next year

The module ship also delivered about 700 kg of various cargoes to the ISS, including resource equipment and consumables, water treatment, medical control and sanitary and hygienic supplies, maintenance and repair facilities, as well as standard food rations for the 66th crew. main expedition.

MOSCOW, November 26. / TASS /. Roskosmos handed over to law enforcement agencies all the results of the investigation on the reasons for the appearance of the hole found in the living compartment of the Soyuz MS-09 spacecraft when it was on the ISS. This was reported by the press service of the state corporation on Friday.

"All the results of the investigation regarding the hole in the utility compartment of the Soyuz MS-09 spacecraft were transferred to law enforcement agencies," the Roskosmos noted.

Earlier on Friday , Izvestia, citing sources, said that the hole could have appeared due to the desire of NASA astronaut Serina Aunyon-Chancellor to return to Earth due to the formation of a blood clot or a conflict with her lover on board the ISS.

Earlier, a source told TASS that a hole in the living compartment of the Soyuz MS-09 spacecraft in 2018 was drilled in zero gravity by a person who was not familiar with the device.

IMHO the Vega program was probably the pinnacle of Soviet-era planetary exploration and has has been unfairly ignored by Western pundits.  Landers on Venus nightside, balloons in its atmosphere, and Comet Halley fly-bys, what's not to like.  It is true that its solid-state cameras for the Halley encounter were a living example of 1st-gen technology with horrendous noise currents, but they captured some great imagery that I believe out did the more lauded Giotto probe.

I'll bet few have seen this one before...

PD must be the down-vote imbecile. The moron can't even be bothered to make his "case". Only serial pissing on the thread.

a bit long but it's worth the watch



I'm always told what if .... what would the USSR's space program have achieved if it hadn't collapsed, we'd have Energia-Buran, a reusable launch system, in service RD-170, maybe a base on the moon? and even more closed cycle engines as if we don't have enough of those lol...

With regard to the very ancient Slavs that would be the Neuri not Scythians.


Visigoths living on the Iberian Peninsula claimed to be of Scythian origin, so I guess it is Catalan.

You can ask Saint Isidore of Seville about it, albeit he is dead.

MOSCOW, December 2 - RIA Novosti. The state corporation Roskosmos has identified a place at the Vostochny cosmodrome for the launch and landing of the Russian reusable Amur-LNG rocket, said Alexander Bloshenko , executive director of Roskosmos for promising programs and science .

Bloshenko recalled that Roskosmos ordered the development of a preliminary design for a medium-class Amur-LNG methane carrier rocket with a reversible stage in 2020.

“This year we performed a reconnaissance at the Vostochny cosmodrome and identified the locations for the launch complex, for the landing complex. We have taken into account the safety of all facilities of the cosmodrome, "Bloshenko said at the VI All-Russian Forum of Cosmonautics and Aviation" CosmoStart ".

The executive director noted that, according to the corporation's plan, it should be a separate complex, with a separate infrastructure - from a souvenir shop to a modern observation deck.

He explained that initially Amur is being developed as a commercial launch vehicle, its main priorities are reliability, payload mass and economic efficiency. Bloshenko added that methane and recoverability are tools to achieve these priorities.

MOSCOW, Dec 3 - RIA Novosti. Roscosmos specialists will begin testing a reusable stage of a launch vehicle in the form of an unmanned aerial vehicle (UAV) - it will take off from an airfield like an airplane, a source in the rocket and space industry told RIA Novosti.
In Russia developed a reusable rocket stage light "wing-SV" since 2019. It is planned that it will be able to return from space by descent in horizontal flight with landing both on the runway and on the ground.

"One of the demonstrators of the reusable stage of the Krylo-SV light rocket will be equipped with a landing gear and a turbojet engine, as well as an aircraft-like nose cone, which will allow it to take off, fly and then return to the airfield. In fact, it will be a UAV created on the basis of the future rocket stage to test the characteristics of the flight of the stage in the atmosphere, "- said the agency's interlocutor.

He specified that one of the military airfields will be the site of the tests.

"The timing of the tests has not yet been precisely determined, preliminary, the first atmospheric flight of the demonstrator stage should take place in the second half of 2022," the source said.

The interlocutor added that the reusable stage of the launch vehicle will be equipped with a rectangular wing, which, according to experts, will be effective both when braking the stage in dense layers of the atmosphere, during descent from space, and in subsequent air flight.

"The reusable stage with atmospheric flight capability will allow Wing-SV to be launched with a wide range of inclinations, since it will be able to return to the cosmodrome after flying hundreds of kilometers," the source explained.

He recalled that the developer of the Krylo-SV reusable rocket with a reusable first stage is the Design Bureau named after V.I. Bartini (part of TsNIIMash , the head scientific institute of Roscosmos).
