NASA considering commercial communications satellites for Mars
Capitalism in space: NASA officials have revealed that they are considering hiring commercial communications companies to build and launch a communications network of satellites to support its Mars science missions.
In recent presentations to advisory committees, NASA officials have discussed the possibility of working with industry to place several satellites into orbit around Mars that would serve as relays for other missions, notably the proposed Mars Ice Mapper. Such satellites, they said, could greatly increase the amount of data missions can return to Earth and end reliance on aging science missions that also serve as data relays.
One proposal presented at those meetings features three satellites in equatorial orbits at altitudes of 6,000 kilometers. The satellites would be equipped with radio links for communicating with other spacecraft in orbit and on the surface as well as to and from Earth. The satellites may also include laser intersatellite links to allow them to communicate with each other.
Based on the number of missions ongoing and planned for Mars, the agency has recognized it needs to establish a dedicated system for communicating with those missions, rather than depending on the science orbiters they have in orbit. That they are looking to commercial companies to build this for them, with NASA acting merely as a customer, as an excellent sign that the agency has now completely accept this approach, as I recommended in Capitalism in Space, rather than acting as the big boss that controls everything.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
