DailyDirt: Getting Back Into Space
from the urls-we-dig-up dept
Despite a few mishaps with rockets headed for the International Space Station (eg. SpaceX, Orbital Sciences and the Russian space agency all failed to deliver re-supply cargo ships), there have also been some interesting space-faring developments in the last year or so. Fortunately, none of the lost spacecraft were manned missions, and the ISS also has the Japanese HTV as another backup cargo ship. And with SpaceX's awesome recovery with a successful launch, it looks like re-supply missions are getting back on track -- so the ISS will probably keep going until at least 2020 (and maybe a few years more? 2024? 2028?).- The International Space Station has been re-supplied using the Cygnus spacecraft from Orbital Sciences -- on top of a United Launch Alliance Atlas 5 rocket. Orbital Sciences is still working out the bugs for its Antares rocket, but it's looking to restart Antares launches in 2016. [url]
- NASA has a contract with SpaceX for a manned mission to the ISS. With SpaceX getting its re-usable rockets into operation, trips to the International Space Station could get significantly cheaper, but obviously SpaceX has to prove its re-usable rockets are really re-usable (by re-launching one, not just saying it's possible).

- Another private space company, Intuitive Machines, could provide "next day" shipping to the ISS with its Terrestrial Return Vehicle (TRV). Optimistically, this spacecraft could even provide "same day" delivery to the space station if everything works exactly as planned. This spacecraft is much smaller than other cargo ships that can dock with the space station, but it could be useful for time-sensitive supplies and experiments. [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

France & Germany could pull their support of the ISS after 2020...
If people are still committed to maintaining the ISS, SpaceX better get launch costs down as soon as possible.

Bigelow Aerospace has a contract with NASA to connect one of their expandable modules to the ISS as a technology demonstrator. I think it's only a matter of time before launches are cheap enough to start building a private, commercial station using Bigelow modules.
If I were Elon Musk and I wanted to retire on Mars, an LEO way station in an equatorial orbit is where I'd focus my energies next.
Just saying.

For manned missions to the moon and beyond you DON'T want to start from an equatorial orbit. That would take you through the worst of the Van Allan belts. The Apollo missions, leaving from Cape Canaveral's 28.5 degrees north, missed most of the radiation. It would be the same for trips to Mars.
ISS's 51.6 degree inclination is better for tourism and earth observation science. The view from an equatorial orbit is the same on every orbit, it's almost all water, and the rest is mostly poor Third World countries. Those tourists will want to see their own countries and cities from orbit.
Even the step up from 28.5 degrees to 51.6 degrees greatly increases the percentage of Earth's land area you cover. Skylab went to a 50 degree orbit for Earth-resources coverage, despite the payload penalty.

If your goals are moon and Mars missions, then you have to balance the two.
The reason for ISS's high orbital inclination is because "51.6 degrees is the lowest inclination orbit into which the Russians can directly launch their Soyuz and Progress spacecraft." Any earth observation science is a fortuitous secondary.

They're best bet is to fire a new one off for a manned mission then reuse it for a commercial satellite payload.

To put it into perspective, think about the last time you flew on an airplane. It cost a few hundred dollars, most likely, to take a trip on a jet valued in the tens of millions of dollars. Imagine what air travel would be like if, for every flight, you had to build an entirely new plane.
That's what SpaceX is on the verge of overcoming.
