Some quick updates:

• SpaceX here: Been a little while since I got one of these notifications, but SpaceX says it's planning a louder-than-usual test at its McGregor site as early as Sunday, Jan. 5. Pure speculation here, but this might be the full-up burn for the first stage headed to Florida for the next Dragon cargo flight to the International Space Station, currently set for Feb. 22.

• SpaceX there: The U.S. Air Force Eastern Range has approved dates for the next SpaceX flight, lifting a Thai communications satellite into orbit. That launch had been scheduled to happen today but SpaceX wanted to take a closer look at the fairing protecting the Thaicom-6 during ascent.

The launch is currently set for 4:06 p.m. CST Monday (the window closes at 6:08 p.m.) from Cape Canaveral Air Force Station, Fla. The backup launch day is Tuesday, with a 4:07-6:08 p.m. CST window.

The Tuesday date had been in question because of a conflict with another launch — but...

• Cygnus delayed a day: ...the launch of SpaceX's rival for American cargo flights to ISS, Orbital Sciences' Cygnus spacecraft, has been postponed a day due to weather concerns (i.e., all that snow hitting and about to hit the Northeast). The new date is no earlier than Wednesday; if that is the date, launch time from Wallops Island, Va., is set for 12:32 p.m. CST.
