今天pass项目2,@carv_official #carv $arc
其实吸引我的是这张图,让我情不自禁想起了虫子项目 #webb
还有之前带社区成员做了个sol链上的nft项目,mint价格2sol,很快就涨了20多(适当吹吹),那时候sol价格100以上
但这个项目并不是做游戏的,而是偏向游戏的DID,对标 #projectgalaxy 差不多
现在说说项目
1)项目立意应该是在链游井喷,公会爆发的时期,那时候大家觉得链游yyds,永远牛逼
于是 carv就做了一个以钱包作为基础,收集各种玩家的数据,做成徽章和数据集成的协议
对玩家来说,对标王者荣耀个人面板的东西,一来比较酷炫,二来能够吸引潜在投资人和老板
2)
对公会来说,他们也希望找到更多,游戏水平高,却比较穷的小伙子,培养培养,去打竞标赛不香吗?比如竞技类的 $thg ,甚至 @mobox 吧(其实还是忽悠玩家的)

Around May 24, JWST sustained a dust-sized micrometeroid impact to its primary mirror segment C3. Initial assessment shows that the telescope's performance remains above all mission requirements although there is a marginally detectable effect in its data.
1/
The size of the micrometeroid and the physical nature of the damage are not clear from the report. JWST does not have cameras to observe such damage. The impact of the micrometeroid is judged based on its effect on image quality.
2/
Such micrometeroid events are expected and have been simulated and tested on the ground. Since launch, there have been 4 smaller measurable micrometeoroid strikes; the latest one is larger than the degradation predictions assumed by JWST engineers.

Breaking News 📣 #Hubble breaks new record detecting the most distant individual star ever seen. Nicknamed Earendel by the authors, this star existed within the first billion years after the Universe’s birth in the Big Bang 🎆

Full story: 🔗 esahubble.org/news/heic2203/

Thread 👇 Image
📌 The newly detected star is so far away that its light has taken 12.9 billion years to reach Earth, appearing to us as it did when the Universe was only 7% of its current age.
🗨️ "It’s like we’ve been reading a really interesting book, but we started with the 2nd chapter & now we will have a chance to see how it all got started,” said astronomer Brian Welch of the Johns Hopkins University in Baltimore, lead author of the paper

1/ 📢 This is an image mosaic of 18 randomly organised dots of starlight, the product of #Webb 's unaligned mirror segments all reflecting light from the same star back at Webb's secondary mirror and into #NIRCam's detectors. Thread 👇 with a surprise at the end!
2/ The mosaic was created by pointing the telescope at a bright, isolated star in the constellation Ursa Major known as HD 84406, chosen specifically because it's easily identifiable and not crowded by other stars of similar brightness, which helps to reduce background confusion
3/ Each dot within the mosaic is labeled by the corresponding primary mirror segment that captured it. These initial results closely match expectations and simulations.

Taking #Webb's temperature 🌡️ 5 new temperature monitoring points have been added to the NASA website to track cooling and status of the instruments during the post L2 arrival commissioning process. Let's have a look at them 👇
1/ Temperature control is a vital aspect of #Webb 's design, engineering and operations. On the page you can see 2 "hot side" and 2 "cold side" temperatures and a set of bellweather instrument temperatures
2/ The instruments are located within the Integrated Science Instrument Module and the Fine Steering Mirror is located within the protrusion in the center of the primary mirror

Some of you asked recently why are #Webb's mirrors hexagonal? Thread 👇
📷 NASA/Chris Gunn
1/ The hexagonal shape enables a roughly circular, segmented mirror with "high filling factor and six-fold symmetry." High filling factor just means the segments fit together without gaps, which would not be the case if the segments were circular
2/ Symmetry is good because only 3 different optical prescriptions (A, B and C) are needed for 18 segments, 6 of each as seen below 📷 NASA

As #Webb is going through the focusing of its mirrors, let's look into what this process entails. #WebbSeesFarther 👇
1/ #Webb's 18 hexagonal mirrors have already been unfolded a while back, but now it's time for a more precise alignment so they point in exactly the same direction 🎯 and deliver sharp images.
📷 NASA/Chris Gunn Image
2/ These corrections are made through a process called 〰️ wavefront sensing and control, which senses and corrects any errors in the telescope's optics, aligning the mirrors to within tens of nanometres

1/ While we wait for news on L2 orbit insertion, we've got some facts for you on #Webb's orbit 👇
2/ Unlike @Hubble_Space #Webb will not be in orbit around the Earth, but will orbit the Sun, 1.5 million km away from the 🌍 at what is called the second Lagrange point or L2.
3/ This orbit lets the telescope stay in line with the Earth as it moves around the Sun. This allows the satellite's large sunshield to protect the telescope from the light and heat of the Sun, Earth and Moon.

As we approach final destination, let's take a moment to recap all the incredible steps #Webb went through so far. Thread 👇
1/ Webb's journey to space started in French Guiana, at the European Space Port. Here's why this was an ideal launch side for #Webb
2/ On Christmas Day 🎄, @Ariane5 made a flawless launch of the James #Webb Space Telescope. #WebbThanksAriane

1/ The Mid-InfraRed Instrument #MIRI is one of 4 instruments on the James #Webb Space Telescope. The only mid-infrared instrument in its instrument suite. #WebbSeesFarther
📷 NASA/ Chris Gunn
2/ Thanks to state-of-the-art instrument design and components, it will deliver mid-infrared images and spectra with an unprecedented combination of sharpness and sensitivity. #WebbSeesFarther
3/ #MIRI will be capable of penetrating thick layers of dust obscuring regions of intense star birth. It will see the first generations of galaxies to form after the #BigBang, and it will study sites of new planet formation and the composition of the interstellar medium.

A work of patience:
The #NASAWebb mirror deployment has started yesterday, moving ~1 mm/day for the next ~10 days for a total of 12.5 mm.
After that, they’ll be ready for @NASAWebb ultimate goal: mirror alignment! #JWST
Each mirror has an individual designation: A, B, or C. This denotes to which segment belongs each of the three mirror prescriptions.
Each mirror, for better support during #Webb space ride, has on its back three rigid metal pegs. These nestled into matching holder sockets in the telescope structure. Before launch, the mirrors were all positioned with the pegs held in the sockets, providing extra support.

1/ As we wait for full mirror deployment, here are some cool-to-know facts about #Webb 's mirrors.
📷 Northrop Grumman, NASA/Chris Gunn
2/ #Webb has a primary mirror 6.5m across as this is what was needed to measure the light from very young galaxies 🌀 over 13 billion light years away.
3/ A mirror this large had never before been launched into space! If the @HUBBLE_space 2.4 m glass mirror were scaled to be large enough for #Webb, it would be too heavy to launch into orbit.

1/ While everyone's eyes were on the shield tensioning, the Mid-Infrared Instrument (MIRI) provided by @esa for #Webb also had an important milestone: unlocking the Contamination Control Cover, which had to be locked for launch.
🔗 blogs.nasa.gov/webb/2022/01/0…
🎥 ESA/ATG medialab
@esa 2/ After successfully completing the tests and unlocking the cover, the instrument control electronics were then powered off before the next steps on the sunshield tensioning activities.
@esa 3/ This key step for MIRI was monitored remotely by team members in Europe, ready to provide assistance if it were needed.

#WebbFliesAriane J-1 🚀 Si le décollage approche, ce n'est pas encore la fin du voyage : la mission d'Ariane va durer une demi-heure, le temps de placer #Webb sur la trajectoire vers son orbite finale. #UnfoldTheUniverse
#WebbFliesAriane Il faudra 1 mois au télescope #Webb pour rejoindre sa destination à 1,5 million de km de la Terre. Durant ce voyage, le télescope va déployer son panneau solaire et son pare-soleil pour faire refroidir ses instruments.
#UnfoldTheUniverse
#WebbFliesAriane Une fois en orbite autour du point de Lagrange 2, les instruments seront mis en route puis testés. Les premières observations scientifiques commenceront au bout de 6 mois. #UnfoldTheUniverse

Tras recorrer el Museo "Victoria y Alberto" en Londres,... ¿vamos a comer algo en la primera cafetería que hubo en un museo?

Venga, vamos y de paso vemos algo de su arquitectura y decoración, que os va a sonar...

El director fundador del museo, Henry #Cole, creó unas exposiciones con lo mejor en artes y ciencias del momento, pero quedaba un poco lejos, así que para atraer a los visitantes les anunció que disfrutarían de una primicia mundial: un restaurante dentro del museo.

Sigue👇🏽
Al entrar al Museo desde el jardín, el público no entraba a las galerías con exposiciones, sino por tres arcos con puertas de vidrio que conducían a un trío de salas de refrigerios, una manera de motivar a los visitantes y cubrir sus necesidades (hambre y sed).
