    I don't know much about Soyuz. They use the same propellant as SpaceX Falcon 9, a cleaner version of Kerosene, in the US called RP-1 and LOX, liquid oxygen as oxidizer. They indeed get the exhaust away from the rocket better than at the US launch sites. That's because the US sites are in a very flat landscape at the coast. They fire into flame trenches and spray a lot of water to limit noise and heat. The russian launch sites are deep inland. They place their launch pad on top of a cliff and the rocket exhaust can go way down without needing a flame trench and water spray.

    Before the Dragon capsule NASA was never able to keep the ISS permanently manned on its own, even with the Shuttle around.

    They could bring crew up with the Shuttle, but the Shuttle could stay up only a short time, maybe 2 weeks. When it leaves the astronauts would be without a life boat in case of any emergency. The life boat was a Soyuz capsule. NASA had planned to build a capsule, not for launch, only as a life boat for emergency landings. But that plan was abandoned in favor of using Soyuz. It seemed appropriate at the time to support Roskosmos after the collaps of the Soviet Union. Roskosmos did not charge an outrageous fee like they did later, when the Shuttle was terminated. At that time Soyuz was the only vehicle, up and down, until Dragon.

    This fact was not widely advertised. Many were not aware.

    Japanese astronaut Soichi Noguchi demonstrates the SpaceX board suit that can protect astronauts in case of pressure failure of the Dragon capsule. 3 videos.

    Video1, explaining the suit. In japanese but subtitles can be selected. Fascinating that the air tight seals are just zippers. Not newly invented by SpaceX. That type of zippers were invented before.


    Donning the suit, very simple, possible without help.


    Doffing the suit, again simple, without help.

    Any news from Mars. Have they all arrived safely? Still just NASA landing their buggy?

    They have all arrived in Mars orbit. No failures so far. The Chinese lander is expected to land in May. Unlike the NASA lander it entered orbit. They will survey the landing site with their orbiter before they attempt landing. Landing is hard, I hope they succeed.

    The NASA helicopter is days away from first flight. It was dropped from the rover and is healthy on the ground, except a small computer glitch which delayed first flight but seems no problem.

    'Off we go!' Russian cosmonaut Yuri Gagarin made history 60 years ago today by becoming the first human in SPACE

    Yuri Gagarin became the first human in space in the Russian capsule Vostok 1

    He completed one orbit of the Earth inside his small capsule on April 12, 1961

    This was a major milestone that spurred on the Soviet Union and US space race

    April 12 is also the anniversary of the first NASA Space Shuttle mission

    12 April 2021

    It is 60 years since Russian pilot and cosmonaut Yuri Gagarin became the first human to leave the embrace of planet Earth and venture into space.

    To mark the occasion people, space agencies and governments around the world are celebrating the International Day of Human Space Flight in his honour.

    On April 12, 1961 the 27-year-old Gagarin climbed in his Vostok 1 capsule, ready for the 108 minute flight, shouting 'Poyekhali!' - 'Off we go!' - as the rockets fired.

    Gagarin launched from the Baikonur Cosmodrome where Roscosmos Soyuz flights to the International Space Station (ISS) are still being launched.

    French astronaut Thomas Pesquet paid tribute to Gagarin, saying he is a paragon for all astronauts and cosmonauts that have followed in his footsteps.

    Since Gagarin's flight hundreds of people have flown into space, with most travelling to the International Space Station - only 24 have gone beyond low Earth orbit.

    Windows updates are due today

    NASA will upload a "minor modification" of flight control software to the Ingenuity helicopter ahead of its first attempt at powered flight on Mars, and says the process of doing so means it can’t say when attempts to send craft into Red skies will take place.
    The ‘copter was scheduled to attempt flight on April 11th, but NASA delayed lift-off due to a rotor spin test ending early “due to a 'watchdog' timer expiration".
    Now the space agency says that problem can only be overcome by new software.
    “The Ingenuity team has identified a software solution for the command sequence issue identified on Sol 49 (April 9) during a planned high-speed spin-up test of the helicopter’s rotors,” says NASA’s new statement.
    Other options were considered, but it was decided that “minor modification and reinstallation of Ingenuity’s flight control software is the most robust path forward.”
    “This software update will modify the process by which the two flight controllers boot up, allowing the hardware and software to safely transition to the flight state.”
    NASA writes software update for Ingenuity helicopter to enable first Mars flight • The Register

    RE: The watchdog timer expired.

    I apologize for the delay in responding. After reviewing the errors and doing some research, the error is coming from Dell's OpenManage software v7.2 . Our recommendation is to update your OpenManage to version 7.3 and monitor. This version should address the timeout error in this particular service is giving the watchdog error.

    The name lost in translation ...

    Who’s afraid of Yuri Gagarin? State Department celebrates space day by ERASING first man in orbit

    Celebrating the anniversary of human spaceflight but omitting the name of Yuri Gagarin suggests that the US establishment is so insecure that it seems physically incapable of acknowledging any achievements of non-Americans.

    Boomers are not going to forget. I remember sputnik, we all went outside at night with our binoculars and telescopes to see it. Living in the desert in Arabia it was clearly visible. Then a couple of years later being shocked that the USSR beat us into orbit with Yuri Gargarin, hell I remember when they shot up Valentina Tereshkova the first female cosmonaut as well. Then all we did was go up to space and come right back down with Shepard and then Grissom. Finally we got John Glenn into orbit. But every American boomer for sure remembers who dominated the early space voyages.

    Laika, the first (?) animal to orbit the earth a few years before Gagarin.

    Once I discovered that this was not at all fun for the dog I sort of put this achievement out of my mind. In reality it was a brutal one way trip for the poor stray dog.

    ^^ As I posted everybody I knew. Took a while before the truth was sniffed out but when it did it was well publicized.

    An earthquake with Tsunami in the space industry.

    NASA has officially selected SpaceX Starship as the Artemis Moon lander. NASA had wanted two companies but decided for only one because of funding restrictions.

    The 3 proposals separately.

    The 3 scaled to size.

    The Blue Origin/Natonal Team proposal cut their price in half to stay in the race but were still to expensive for NASAs budget.

    Yes, it is. It is a revolution in size and capacity and is supposed to be as revolutionary in cost.

    Now I have slept over it and had the chance to think about it I am deeply suspicious. This came out of nowhere yesterday. The press conference was called so suddenly that SpaceX did not even have time to be represented. It lets me think that NASA made their decision and made it public immediately, before Congress could put pressure on them, to change it.

    These are old renders. There was a new one yesterday, with some changes, but the size remains.

    Looks like at risk of toppling over if it isn't landed on a perfectly flat hard piece of rock.


    Will it have some sort of anchors or something underneath it that secures it? (I'd imagine not)

    They do seen oddly impractical, sitting there like that....like those pictures of rockets from the covers of 1950s science fiction novels.

    Last night I used an old picture, an early design. Yesterday they released a new render, with better legs. They also can do precision landings. NASA can select a site with very flat surface.
