Earlier this week, SpaceX conducted another test of its Starship. However, the booster was damaged by an explosion during a pre-launch test and will now need to be inspected to determine whether it can be used in the inaugural launch of the Starship later this summer.
For more on the Starship, check out the Cool Worlds video titled “Why Starship Could Transform Astronomy.” It argues that reduced launch costs, reduced complexity, and heavier payloads would allow NASA to launch a fleet of telescopes within current budgets. For instance, the larger Starship payload would have allowed NASA to avoid all of the contortions necessary to fold the James Webb Space Telescope into a smaller rocket. The video also argues that SpaceX’s willingness to take risks is something NASA may want to emulate.
These are interesting times with NASA and SpaceX testing new rockets to place astronauts on distant objects. Even if Russia wants to sit this one out, we have a full blown space race underway domestically.

Earlier today, President Biden released one of the first images (shown above) from the James Webb Space Telescope (JWSP). A full release is scheduled for tomorrow at this location: https://www.nasa.gov/webbfirstimages.
The image shows galaxy cluster SMACS 0723, which represents thousands of galaxies in a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.
Here is a little more from NASA on what we are seeing:
The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions, as Webb seeks the earliest galaxies in the universe.

This week’s image is the Hubble Space Telescope, still going strong after more than 32 years. It left the Space Shuttle Discovery’s cargo bay on April 25, 1990. With all of the attention on the James Webb Space Telescope (JWST), it’s important to remember this dependable space telescope that brought us so many amazing images over the years, including those shown below.
Given the concern over the recent concerns about a micrometeroid impacting the JWST, let’s not forget that the Hubble had a few growing pains as well. Most importantly, it had to deal with a flawed mirror that required astronauts to visit the space telescope so they could add five pairs of corrective mirrors. More than three years had passed before the astronauts could make this correction. So the current issues with the JWST are pretty minor by comparison.

If you are looking for space series beyond the Moon, PBS has a few more shows for you. With the James Webb Space Telescope releasing the first photos next week, now is the time to brush up on the mission with a NOVA special. And check out the earlier NOVA piece on the planets as well. Dates and times may vary by region.
How did NASA engineers build and launch the most ambitious telescope of all time? Follow the dramatic story of the James Webb Space Telescope—the most complex machine ever launched into space. If it works, scientists believe that this new eye on the universe will peer deeper back in time and space than ever before to the birth of galaxies, and may even be able to “sniff” the atmospheres of exoplanets as we search for signs of life beyond Earth. But getting it to work is no easy task. The telescope is far bigger than its predecessor, the famous Hubble Space Telescope, and it needs to make its observations a million miles away from Earth—so there will be no chance to go out and fix it. That means there’s no room for error; the most ambitious telescope ever built needs to work perfectly. Meet the engineers making it happen and join them on their high stakes journey to uncover new secrets of the universe.
Among the stars in the night sky wander the eight-plus worlds of our own solar system—each home to truly awe-inspiring sights. Volcanoes three times higher than Everest, geysers erupting with icy plumes, cyclones larger than Earth lasting hundreds of years. Each of our celestial neighbors has a distinct personality and a unique story. In this five-part series, NOVA will explore the awesome beauty of “The Planets,” including Saturn’s 175,000-mile-wide rings, Mars’ ancient waterfalls four times the size of any found on Earth, and Neptune’s winds—12 times stronger than any hurricane felt on our planet. Using unique special effects and extraordinary footage captured by orbiters, landers and rovers, we’ll treat viewers to an up-close look at these faraway worlds. We’ll stand on the dark side of Pluto, lit only by the reflected light of its moons, watch the sun set over an ancient Martian waterfall, and witness a storm twice the size of Earth from high above Saturn. And, we’ll reveal how each of them has affected our own planet: Earth.

“It’s really hard to not look at the universe in a new light and not just have a moment that is deeply personal…It’s an emotional moment when you see nature suddenly releasing some of its secrets, and I would like you to imagine and look forward to that.”
