I’ve uploaded my footage from Artemis 2’s first rollout back in January. I have another scripted SLS video in the works but in the meantime- I will work to make a compilation of all my Artemis 1 footage (such as VAB B roll & rollout) into a video too. youtu.be/WfmmHj3Vg_4?si…

I mean, that's definitely one of the quickest ways to reopen the Strait of Hormuz.

@Eric3Gribble @AeroBigMike This also expresses that (although, in this case, the excitement has just been rekindled). There's hope... youtu.be/ZI_yNFKMUSs?si…

You will hate me but this is how I see things. I am not nostalgic about the shuttle . I am almost 70 years old and consider the shuttle era to have been a massive misguided period of lost opportunity. During the 1960's NASA built a moon rocket using the technology of the time. this required a great deal of innovation as it was all new, never done before stuff. After Apollo the decision was made to make a step into reuse with the space shuttle which was an amazing concept at the time. This is when everything went wrong. The shuttle failed to reach the required cadence, and was far more expensive to operate than a conventional expendable rocket. This is when the plug should have been pulled on the program. Instead the shuttle was persisted with for 30 years. During this time operational costs prevented resources from going into new developments. SRB's proved to be dangerous and unsuitable for reuse. the shuttle engines (at the end of the program) were built using antiquated production techniques instead of being almost fully 3D printed. At great expense the mobile launch platform technique for getting each system to the pad was still being used. Then some bright sparks decided to incorporate all these excessive operating costs into a new launch system, the SLS. The original idea was to save costs by reusing what had already been developed, but instead everything wrong with the shuttle was kept. A bit like trying to build a modern motorcar out of ford model-t parts. At the time of Apollo China's main agricultural machine was the oxen and the main means of transport the pushbike. Now the U.S. is in a race against China to get back to the moon. That is how much lost opportunity there has been. .

@AeroBigMike I thought you all should keep this perspective in mind (because many people don't understand why this is exciting). Here's someone who rediscovered it... youtu.be/ZI_yNFKMUSs?si…

Here's an important video about sharing the upcoming Artemis 2 return to the moon--a must see if you already care! youtu.be/ZI_yNFKMUSs?si…

おはようございます。雲が多かったけど星が見えていたのでベランダで撮影。アトラス彗星とパンスターズ彗星

There's hope yet, for C/2026 A1.....

El segundo vuelo del lanzador de pequeños satélites #Spectrum de la empresa europea @isaraerospace, en la misión 'Onward And Upward', fue detenido a solo 3 segundos del despegue en Noruega, tras un retraso previo por una embarcación en la zona de seguridad.

For those interested, a newly discovered Comet C/2026 A1 (MAPS) is expected to be visible in the day sky around April 4-6…. ☄️ ☀️ space.com/astronomy/come…

Comet C/2026 A1 (MAPS) is now brightening rapidly? The latest reported brightness estimates and measurements seem to indicate the comet is now between magnitudes 8.5 and 9.0. It is at this point unclear whether this is an outburst or if the comet has resumed 'regular' brightening. All bets are off.

This girl is still alive, and there is still time to act... help bring attention to her case so we can save her life I never ask for anything, but please RT and pray

マップス彗星C/2026 A1（MAPS）、中央を大きく外してしまいましたが、何とか写野内に居ました。拡大すると淡い尾が左（東）の恒星方向にあるようです。 2026/03/23 19h20m（JST）～30sec×9 ISO3200 16cmF4.8ニュートン直焦点 PENTAX KF

短焦点で春は撮る物が無いので、高度30度に満たない北アメリカ星雲を撮影。 低空なのに良く写った。 SV555/SC571CC/3分×9枚

4月に明るくなると期待されているMAPS彗星（C/2026 A1）、ここにきて明らかに光度の伸びが悪い。彗星は既に金星よりも太陽に近く、本来なら指数関数的に明るさが増していなければならないところ。それが直線状にしか増えていないというのは、物質の噴出が早い段階で限界量に達してしまったか……？

This month on March 25th 1996 great comet Hyakutake put on a tremendous show. Closest to Earth not far from Polaris & visible for much of the night. Coma approx 2 degrees wide and naked eye gas tail 80 to 100 degrees long, blue in colour. Discovered using 6" binoculars.

Facebookで50 and 30 yrs ago !と言う投稿を見たので、私もこの素晴らしき大彗星をアップしておきます。West彗星は１９７６年３月４日、百武彗星は１９９６年３月２５日です。初めて見た大彗星West彗星と、天を二つに割る長い尾を見せた百武彗星は、私の記憶の中でも特別です。
