magnitude 4.7 earthquake in the southwest of Iceland
in Svartsengi, near the Blue Lagoon,
moderately close to Reykjavík
Svartsengifell is part of a row of volcanic craters on the southwest spur of the Atlantic rift.
The area went through intense series of eruptions about 1,000 years ago, which…

North Korea is claiming a second, successful, nuclear device test.
Coincident with a shallow medium magnitude earthquake in the test region.
Earthquake is magnitude 4.7 or so on the Richter scale (Swiss are estimating 5.1).
Very shallow, consistent with surface origin, 380 km north east of…
Atlantis has landed safely. Hubble servicing mission is finished.
It woke me up coming down.
Atlantis landing had been delayed for two successive days because of weather, so this morning they diverted the landing site to the backup location at Edward's Air Force Base, just over the mountains from…

Spitzer is out of cryogen.
Cold mission is dead.
Long live the warm mission!
It is official, as of this weekend, the Spitzer Space Telescope is out of coolant (liquid helium), right on schedule.
This will basically end mid-IR observing, MIPS will not be taking data, as I understand it,
nor will…

Hubble repairs are done.
FGS replaced and blankets installed.
Now it just need to be dropped off in orbit - presumably with as good a reboost as they can manage, and then get Atlantis home safely.
Phew.
The wait for orbit verification, first light and calibration.
Rumours are that a new Administrator for NASA may be named this week
