🔴Port mirror wing deployment has begun! The wing only needs about 5 minutes to rotate into position, but will need at least two hours to latch it into place. That's probably why the starboard wing doesn't open until tomorrow. But we're on the final approach to an unfolded telescope!

@rowenhusky 2 года назад

If there is lets say a MAJOR issue that cannot be corrected...couldn't JWST technically burn to return to earth orbit so at least it could be serviced and then fired again later back to L2? I know this would be insanely costly but much less than losing the entire thing.

@LaunchPadAstronomy 2 года назад

I don’t know if it has enough delta-v to turn around and burn for home but even if it did, doing so would expose the telescope to the sun, causing it to overheat well beyond limits. That would render the telescope unusable at that point.

@@jc4evur661 There are always slight differences between the way the spacecraft systems operate in space, versus during ground test. Although they try to replicate the space environment as well as possible during ground test, it isn't possible to get this perfect. They are examining lots of data - temperatures, battery condition, power usage, solar panel output, etc., to make sure everything is within required ranges. As of Monday Jan. 3rd, they have made two tweaks: 1. Solar panel regulators have been adjusted to match power needs better. These were initially set to factory defaults, but they have now been individually optimized. 2. Shield tensioning motors were a few degrees warmer than they wanted, so they adjusted the spacecraft attitude for a while, to reduce sun exposure and get them down to the desired temperature.

As a kid I witnessed the first moon landing and saw the capsule up close after it's return. Back then it seemed rugged, crude, built to withstand heat and a lot of forces. In contrast this space instrument is an example of an extremely precise and well thought out combination of structures that operate in unison so that each component can play its vital part. Like the Apollo capsule, it needs to cope with the extreme environment of space, yet this seems to be 'brain in stead of brawn-design' . I am very very impressed indeed. I can't wait to hear & see more about it's progress. Thank you for your presentation. Willem

when you put it that way, it sound much better for JWST... lol.. 🍻

As a project manager, I am in absolute awe at the logistics and planning that must go into these Nasa projects. While there is beauty in "Keep it Simple Stupid" there is pure wonder when something insanely complicated executes flawlessly and delivers far greater results.

Now I understand why James Webb Telescope was delayed countless times for years. One single error and poof... there's your $10B space junk. This is a masterpiece of an engineering, so much complex ways for it to work, mad respect for those who made this possible for us earthlings to know more of the secrets the universe has store for us, it's gotta be mind boggling to even comprehend about.

If the JWST, with a projected lifespan of 10 years, had been launched in 2007 as it was originally planned, then it would be history by now.

@okankyoto 2 года назад

Good launcher performance has led NASA to say they now expect it to have a lifespan closer to 20 years!

@Capt.Turner 2 года назад

Great video ! Left a subscription. I'm wondering how they get precise enough position readings that far away from Earth and what the margin of error for position determination is, to get James Webb safely into its L2 orbit.

@zounds010 2 года назад

They are measured from Earth, using the radio link. Distance is by sending a signal to JWST, then timing the echo. The Doppler on that gives the speed (down to mm/s). Lateral position is a bit less accurate if they use one station on Earth, but they could triangulate.

@Capt.Turner 2 года назад

@@zounds010 Yeah, the lateral part is what concerns me. Not much of a triangle at that distance.

@dotnet97 2 года назад

@@Capt.Turner Lateral position would've been sorted out within the first 2 burns when it was close enough to Earth for regular old triangulation. The farther out it gets, the more fuel lateral corrections would take.

Thanks for a great exposition of the reasoning behind the deployment sequencing! I, along with many other folk, am holding my breath and have my fingers crossed (and many other things!!!) for a succesful mission! So exciting!!
