What Comes After Hubble?
As NASA prepares for the launch of the last Hubble Space Telescope servicing mission next week, astronomers are already anticipating the construction and 2013 launch of the beloved observatory's successor. In the coming weeks, engineers will wrap up testing the segments of the primary mirror on the James Webb Space Telescope, NASA's newest space-bound observatory. Like astronomer Allan Sandage, it will pick up where Hubble left off -- by studying the redshifted galaxies speeding away from us, in an attempt to understand the nature of the accelerating universe and its origins.

5.6.2009 at 10:04pm - Comment by kingz19911 million miles isn't that far, but your kinda right, its not going to be orbiting per se, it will be in the earth sun Lagrangian point L2, where it will be kept in place in the same location in respect to the sun and the earth, by the gravity from the earth and sun. this puts the satellite behind the earth if looking inwards towards the sun. also what i think about this is they need something way better than this to see what we need to see, something like a few hundred meter wide mirror, maybe on the moon? once we eventually have a moon base, this is something they should aim for to utilize the low gravity and no atmosphere and plenty resources, if they can figure how to use it, this could also be used as giant solar power collector when the sun is shining stopping the usability of it as a telescope

Bytes in the Air
As I post this, I am thousands of feet above San Francisco, on a Virgin airplane, surrounded by press and partygoers celebrating Virgin's imminent roll-out of wireless internet to their passengers. The in-flight service is provided by a carrier called Aircell, which spectrum geeks may recall won an exclusive ten-year contract from the FCC in 2006 to provide air-to-ground broadband at 3MHz. Onboard, a standard 802.11 wi-fi network works with all standard devices.
11.24.2008 at 02:54am - Comment by kingz1991This wireless internet that the airlines are providing is only their first attempt. I bet within a year or two that they will have way faster speeds, and will probably be doing it via satellite, as suggested previously, once they see that people are really into it. 3.1Mbps seems pretty slow, that's like the same speed that I have at home. If they tried sharing that kind of speed between like 100 people they wouldn't be able to do much else than just read email. Maybe with better speeds more people will use this, I don't see it being very useful right now.
