    Bad science in fiction Hall of Shame

    in Science & Spaceflight

    Posted

    A new movie got released on Netflix a few days ago called Approaching the Unknown.. (spoilers ahead)

    I thought for a moment it would be hard sci fi but a few minutes into the film they launch a rocket and the austronaut inside actualy has one hand on some sort of a throttle and the other on a flight stick pulling both back like he is flying the thing into orbit.. I knew it would be bad after that.

    The whole premisse of the movie was that the astronaut spend some time in the desert and managed to invent a "water generator" that could extract hydrogen and oxygen from desert soil and produce both power and water from it so they launched a 1 person mission to Mars with this device..

    The rest of the movie is so boring i had a hard time staying awake watching it..

    Also everytime they showed a outside shot of his spacecraft it was flying through some sort of nebula cloud... Really? Since when do we have nebula's between Earth and Mars?

    Really can not recommend this movie it is very very bad...

    Loss of telemetry could be anything from a couple a doves releasing their excrement on the Natal dish reciever to some sensors losing power during the last stage burn..

    The rocket and everything on it is programmed to do everything autonomously so while its not normal is does not have to be a disaster.

    We will know more tomorrow but all the sources i can find say the launch of the satellites itself did not fail..

    Just point out the track record of Ariane Space.. They have been launching satellites succesfuly for so long now 1 failure is not going to hurt them. General media is always looking for sensation, a failed launch is "better" news for them but in the big picture it doesnt matter much. Government agencies know this i would hope.

    With the benefit of its electric thruster orbit-raising package, the SES 14 telecom satellite with NASA's GOLD science instrument is expected to be able to reach its planned position in geostationary orbit.

    The status of the Al Yah 3 satellite, which has a conventional chemical orbit-raising engine, has not been confirmed.

    Nothing is sure yet it could still be a succes..

    Ah like i said:

     

    Arianespace has issued a statement on tonight's mission, confirming both satellites are on orbit and continuing their missions.

    "The launcher's liftoff took place on January 25, 2018, at 720 p.m. (French Guiana time). A few seconds after ignition of the upper stage, the second tracking station located in Natal, Brazil, did not acquire the launcher telemetry. This lack of telemetry lasted throughout the rest of powered flight.
    Subsequently, both satellites were confirmed separated, acquired and they are on orbit. SES-14 and Al Yah 3 are communicating with their respective control centers. Both missions are continuing."
     
    So the lesson for today: Loss of telemetry does not equal catastrophic failure..

    Just in:

    The SES 14 and Al Yah 3 satellites are in orbit after tonight's launch, sources tell Spaceflight Now.

    The SES 14 spacecraft carries an all-electric propulsion system that could give that satellite an advantage in overcoming any orbital shortfall. The xenon-fueled thrusters are more efficient the conventional liquid-fueled engines.

    Al Yah 3's main orbital adjust engine is a hydrazine-fueled thruster more commonly used on commercial communications satellites.

     

    But yeah they where not sure if it was a succes for a bit there...

     

    Here is the statement Arianespace chief executive Stephane Israel:

    "Ladies and gentlemen, I come to give you some information because we have had an anomaly on this launch. Indeed, we lost contact with the launcher a few seconds after ignition of the upper stage. At that time, we can consider that the upper composite and the satellite as being (inaudible). But as I said, we lost contact. Up to now, our customers do not have contact with the satellite. We need now some time to know if they have been separated, and where they are exactly ,to better analyze the consequences of this anomaly."
    "I want to present my deepest excuses to our customers, who have entrusted us one more time. We know that there is no launch with no risk. We know that launch is always difficult, and tonight Ariane 5 has had an anomaly, so lets take time now to better understand the situation of the satellites."
    "Arianespace, in full transparency, will come back to you to provide you with some more information as soon as we have them. I apologize on behalf of Arianespace."

    Yea, but I’m pretty sure there was something along the lines of “and we have a confirmation of the satellite separation...”

    The stream is down, no way to rewatch and check, oh well.

     

    works here?

    Bit of a shame they did not have a camera pointed at the payload.

    Another i thing i noticed at the launch is that the nose cone was seperated in one piece instead of splitting it. Looked cool seeing its reflection on the battery pack before comming in full view.

    @magnemoe: so the rocket is actualy a three stage rocket.. Cool!

    Ofcourse i missed the live launch but i just watched the replay. Great launch the thing was alot louder then i expected.

    Also the corkscrew made me think the thing was out of control for a bit but glad to see everything went well.

    Well done Rocket Lab!

    What was the payload actually?

    Any news on Moon Express?
