    SpaceX is gearing up for at least two Starlink launches next month, beginning with a Falcon 9 mission departing from Vandenberg Space Force Base, California, no earlier than Aug. 10, multiple sources said. Another Falcon 9 launch is scheduled to carry a batch of Starlink satellites into orbit in mid-August.

    Since then, SpaceX has activated hundreds of internet spacecraft delivered to orbit on previous Falcon 9 missions, raising the number of operational Starlink craft from roughly 950 satellites to more than 1,300, according to an analysis by Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics and a widely-respected tracker of spaceflight activity.

    SpaceX has regulatory approval from the Federal Communications Commission to eventually launch and operate up to 12,000 internet relay satellites. The early phases of SpaceX’s Starlink network involves the launch of 4,408 satellites into five orbital shells, or layers, in low Earth orbit.

    12,000, blimey.

    We really do like to spread our pollution far and wide.
    The above may be fact, or fiction, I may be serious, I may be jesting.
    I am not sure. You have no chance.

    The number and scale of all these factories is hardly looking "green".
    Not to mention all the cars used to get to them.

    They have a sh!t load in Bitcoin they don’t give a sh!t about “green”
    Shhhh. Don't let their customers know.
    How do you know someone owns a Tesla? They'll tell you. And go on, and on, and on...
    That applies to many things. Change Tesla for your preferred bike for example. There is a whole thread on BR devoted to it. What carbon fame, wheels, groupset, helmet, gear, power meter...on, and on.
    So would Tesla guy be like the bianchi fanatic?

    1. I was referring to the pollution floating in space, not the fuel to get them there.
    2. We've ruined this planet, let's ruin others.
    3. What's to stop the other planets being hit by asteroids?

    The thing is though when you look at how vast the universe is, relatively Earth mean nothing, a grain of sand on a beach. It means a lot to humanity though and if something happened to it there is another opportunity in Mars to sustain it's exitance.

    All this vibe about saving humanity. Given it is likely a few hundred to thousand would be saved what about those that don't get the lucky ticket to mars. If we were being honest with ourselves if someone was going to wipe out the world's population except a thousand people is there much point in saving humanity.

    That is the same principle as a guy fly tipping. In the big scheme of things neither are important in isolation. Both are still wrong.

    Yeah, well I agree it doesn't worry me in terms of the timescales we are talking about. I'm just interested in the technology side of it.

    If Musk was interesting in saving the world he'd probably not be a billionaire.

    Tech billionaire Elon Musk said Monday that he planned to sell his "last remaining house."

    Musk called the property, in California's Bay Area, a "special place" and said he wanted to sell it to a large family.

    Musk has repeatedly said he plans to sell most of his possessions, including all his houses, to fund a colony on Mars. He has said he wants to send 1 million people to Mars by 2050.

    It follows a ProPublica report last week that said Musk, the CEO of both Tesla and SpaceX, paid $455 million in taxes from 2014 to 2018. His wealth grew $14 billion over the same period.

    If your response to "Earth might become less habitable by humans in the future" is to decide to move somewhere that is already definitely uninhabitable and hope that the humans you take there are going to be different somehow, you're a bit of a nob.

    So what do you say about Martin Tripp the Tesla whistleblower?

    (FWIW, the judge in that case ruled that Martin owed Tesla a lot of money for leaking confidential information, but didn't dispute the content of the whistleblowing).

    There is not enough to go on with that information to make any kind of judgement. Quote the the relevant information and the link.

    And NASA say they can't do what they need to due to lack of funding.

    JFGI - if you are really into the tesla stuff you might as well see what the whistleblower was leaking, no?

    You are one making the point, put some effort in so people can see what it's you are talking about. The other problem is people may just ignore posts like this without context.

    Nuclear propulsion 'holds the potential for significant advantages in terms of efficiency compared to standard chemical rockets'
    WASHINGTON — Space vehicles powered by small nuclear reactors — a technology that NASA believes could help get humans to Mars faster — also could be used for military missions in deep space, the vice chief of the U.S. Space Force said July 28.

    Nuclear propulsion “holds the potential for significant advantages in terms of efficiency compared to standard chemical rockets,” Gen. David Thompson said on a virtual forum hosted by the Mitchell Institute.

    “It expands the envelope in how far you can go,” Thomson said.

    NASA for decades has been interested in nuclear propulsion for space exploration. The Space Force currently does not send missions beyond Earth’s orbit but might have to do that one day, officials predict.

    I read somewhere Russia were looking into this too.

    Stuttgart, 28 July 2021. Porsche Automobil Holding SE (“Porsche SE”), Stuttgart, acquires a low single-digit percentage stake in Isar Aerospace Technologies GmbH (“Isar Aerospace”), Ottobrunn, Munich. The company develops and manufactures launch vehicles for the transport of satellites. The investment was part of a new financing round of Isar Aerospace.

    Lutz Meschke member of the board of management responsible for investment management: “As an investor with a focus on mobility and industrial technology, we are convinced that cost-efficient and flexible access to space will be an enabler of innovation in many industry sectors. With Isar Aerospace, we are investing in a company that is well-positioned to establish itself as a leading European manufacturer of launch vehicles.” The rapid development of the company is impressive, Meschke added.

    Isar Aerospace plans its initial launch next year and offers a more cost-efficient and flexible launch capacity for satellites with “Spectrum”, the first launch vehicle developed by the company. The cost benefits compared to currently available launch vehicles shall mainly be achieved with a high degree of automation in the rocket production process. Due to the latest advancements in the area of satellite technology and resulting business models, e.g., in the areas of connectivity and earth observation, demand for the launch of small satellites is expected to grow significantly in the coming years. As existing launch capacities are not sufficient or too expensive or inflexible, private companies like Isar Aerospace aim to satisfy this demand in a more cost-effective and flexible way compared to established space companies.

    The new financing round has a total volume of around 75 million US dollars. Overall, Isar Aerospace has raised more than 180 million US dollars from renowned investors such as HV Capital, Lakestar, Earlybird and Airbus Ventures.

    With Isar Aerospace, Porsche SE is adding another promising company to its portfolio. The success of Porsche SE’s previous investments was most recently demonstrated by the public listings of its portfolio companies AEVA and Markforged.

    Perhaps they will send a Taycan into space to compete with Tesla's orbital roadster.

    Spectrum is a two-stage launch vehicle that is specifically designed for satellite constellation deployment. Payload capabilities of up to 1'000kg to low-earth orbit and a multi-ignition second stage engine enable flexible access to space for major satellite systems. Spectrum is designed to handle the most challenging mission parameters and offers engine-out capability on the first stage for highest mission success.
