QUOTE (JRehling @ Jun 5 2021, 04:06 PM)  It's not a pure coincidence that we've discovered two interstellar interlopers in the past four years and zero in the previous four hundred years. IIRC, the UVA Charlottesville Astronomy Dept. & Green Bank collaborated on a 25th anniversary t-shirt "President Jefferson Missed The Grand Tour of 1804, and All We Got Was This Lewis & Clarke Expedition T-Shirt" |

The weather forecast at the launch site is for thunderstorms every day for the indefinite future. Launch is delayed at least another day.

Nice daybreak in Kourou, when the birds began to sing!

Textbook launch & separation, successful array deployment, spacecraft is power-positive.
All I wanted for Christmas this year.

Everything perfect throughout launch and 30 minutes into the flight. JWST has separated from the upper stage and has deployed its solar panels, all nominal. Now cruise to its destination continues.

A long journey is over, but another long one has just begun!

Also cool that there are "amateurs" out there receiving and decoding telemetry from JWST. https://destevez.net/2021/12/decoding-james...pace-telescope/

The tracking page's numbers are derived from precalculated flight dynamics data. Means that the numbers are approximate & pre-computed prior to playback you see.
As it stands I understand the telescope's trajectory is spot-on. MCC-1a had the potential to last as long as 3 hours, but thanks to excellent launcher performance the burn only needed to be a paltry 65 minutes. This is a bonus. Means more fuel for stationkeeping. |

Yes interesting that the burns can only speed up JWST due to its constrained orientation. The 2nd 9-minute course correction burn was completed an hour ago. Here are the most recent blog entries.
