Blue Origin’s New Shepard rocket successfully launched and landed today at the company’s Launch Site One in West Texas, with an uncrewed science and goodwill payload onboard. This was the 24th New Shepard flight and 13th payload mission today from Launch Site One in West Texas.

This marked the first flight since September of 2022 when the uncrewed NS-23’s booster suffered an in-flight anomaly; however, the escape system jettisoned the capsule, which was able to land safely. With the success of NS-24, Blue Origin hopes to soon restart its commercial passenger flights.

“We look forward to flying our next crewed flight soon,” said Erika Wagner, senior director of emerging market development for Blue Origin, at the end of the launch broadcast. Watch the liftoff and landing below.

Liftoff occurred at 10:43 Central Time, with the capsule reaching about 106 km (66 miles) at its highest point. The 33 science experiments on board experienced about three minutes of microgravity before the capsule safely touched down under three parachutes — with a retrorocket to cushion the landing — approximately 10 minutes after launch.

The rocket booster touched down vertically about seven minutes after launch, on a landing pad 3.2km north of the launch pad.

The first launch attempt for the mission was scrubbed on Monday due to a ground system issue. But today’s countdown and launch went smoothly.

The payloads on board included research from NASA, academia, research institutions, and commercial companies, as well as student experiments from classrooms in Maine, New Mexico, and Kansas. New Origin said New Shepard has now flown more than 150 payloads to space. Also on board were about 38,000 postcards as part the company’s Postcards to Space program. Each postcard will be returned to its creator stamped “Flown to Space.” To send a postcard on future mission, see the company’s Club for the Future website.

“A special thank you to all of our customers who flew important science today and the students who contributed postcards to advance our future of living and working in space for the benefit of Earth,” said Phil Joyce, Senior Vice President, New Shepard, in a press release. “Demand for New Shepard flights continues to grow and we’re looking forward to increasing our flight cadence in 2024.”

When will New Glenn fly?

Meanwhile, Blue Origin is hoping to finally deliver on their next big project, the massive New Glenn rocket which will be capable of bringing satellites and other large payloads to orbit and beyond. But the rocket is years behind schedule. Initially, Jeff Bezos said that New Glenn would be ready to launch by 2020, but the latest estimate is that the first launch is expected to take place no earlier than August 2024.

NASA and Blue Origin announced in February 2023 that the first launch of New Glenn will carry NASA’s EscaPADE spacecraft to Mars. The Escape and Plasma Acceleration and Dynamics Explorers mission is a small planetary science mission that will use two spacecraft to measure plasma and magnetic fields around the Mars. With simultaneous observations from two locations in orbit, scientists hope to learn more about the processes that strip away atoms from the magnetosphere and upper atmosphere on the Red Planet.

New Glenn will reach a towering height of 95 meters (313 ft) which will dwarf any other commercially available vehicle. And it will be capable of delivering 45 metric tons, almost 100,000 pounds, into space.

But if New Glenn can’t get off the ground by late 2024, it will miss the launch Mars launch window, and the mission will have to be delayed until 2026. Mars launch windows typically come every 26 months. ESCAPADE was originally scheduled to launch as a secondary payload NASA’s Psyche mission which blasted off on a Falcon Heavy rocket in October, but NASA removed ESCAPADE from the launch because it

By Michael Lanza

Chances are that, by now, you’ve heard of Idaho’s Sawtooths—having typed that name into a search box may be the reason you’ve landed on this story. Maybe you’ve been intrigued at what you’ve heard or images you’ve seen from Idaho’s best-known mountain range. Perhaps you’ve even been there and the experience has only amplified your curiosity to see more of this range.

As someone who’s had the good fortune of having backpacked all over the country and in many other countries over the past three-plus decades, including the 10 years I spent as a field editor for Backpacker magazine and even longer running this blog, I rank the Sawtooths among the 10 best backpacking trips in America.

I’ve wandered around the Sawtooths at least a couple dozen times over more than two decades, including numerous backpacking trips, dayhikes, peak scrambles, rock climbing, and backcountry skiing. While there remain peaks on my list to climb, a few trails to hike, and many lakes to leap into (or just sit beside), the Sawtooths have become my backyard mountains. I feel at home there.

This story presents the five reasons I think every backpacker should take a multi-day hike through the Sawtooths—spotlighting the characteristics of a trip there that make this place unique. I believe this argument may persuade you to go (if, somehow, the photos don’t do it).

See my e-book “The Best Backpacking Trip in Idaho’s Sawtooth Mountains” to learn all you need to know to plan and pull off a five-day, 36-mile Sawtooths hike through the core of the Sawtooths, and my Custom Trip Planning page to learn how I can help you plan every detail of a multi-day hike there.

The Venerable Hubble Space Telescope Keeps Delivering

NGC 4753 dust lanes zoom 1024x469 1

The world was much different in 1990 when NASA astronauts removed the Hubble Space Telescope from Space Shuttle Discovery’s cargo bay and placed it into orbit. The Cold War was ending, there were only 5.3 billion humans, and the World Wide Web had just come online.

Now, the old Soviet Union is gone, replaced by a smaller but no less militaristic Russia. The human population has ballooned to 8.1 billion. The internet is a fixture in daily life. We also have a new, more powerful space telescope, the JWST.

But the Hubble keeps delivering, as this latest image shows.

The lenticular galaxy NGC 4753 is about 60 million light-years away. Lenticular galaxies are midway between elliptical and spiral galaxies. They have large-scale disks but only poorly defined spiral arms. NGC 4753 sees very little star formation because like other lenticulars, it’s used up most of its gas. The fact that they contain mostly older stars makes them similar to elliptical galaxies.

Among lenticulars, NGC 4753 is known for the dust lanes surrounding its nucleus. Astronomers think that spirals evolve into lenticulars in dense environments because they interact with other galaxies and with the intergalactic medium. However, NGC 4753 is in a low-density environment. Its environment and complex structure make it a target for astronomers to test their theories of galaxy formation and evolution.

This Hubble image is the sharpest ever taken of NGC 4753, revealing its intriguing complexity and highlighting the space telescope’s impressive resolving power.

Astronomers think that NGC 4753 is the result of a merger with a dwarf galaxy over one billion years ago. The dwarf galaxy was gas-rich, and NGC 4753's distinct dust rings probably accreted from the merger. NGC 4753's powerful gravity then shaped the gas into the complex shapes we see in this image.

NGC 4763’s unique structure results from a merger with a dwarf galaxy about 1.3 billion years ago. The video below from NOIRlab explains what happened.

NGC 4753 also hosts two known Type 1a supernovae, which are important because they help astronomers study the expansion of the Universe. They serve as standard candles, an important rung in the cosmic distance ladder.

Galaxies like NGC 4753 may not be rare, but the viewing angle plays a key role in identifying them. Our edge-on view of the galaxy makes its lenticular form clear. We could be seeing others like it from different angles that obscure its nature.

This is a model of NGC 4753, as seen from various viewing orientations. From left to right and top to bottom, the angle of the line of sight to the galaxy's equatorial plane ranges from 10° to 90° in steps of 10°. Although galaxies similar to NGC 4753 may not be rare, only certain viewing orientations allow for easy identification of a highly twisted disk.

Juno Reveals Secrets About Europa’s Icy Surface

galileo feature 1024x576 1

Europa has always held a fascination to me. I think it’s the concept of a world with a sub-surface ocean and the possibility of life that has inspired me and many others. In September 2022, NASAs Juno spacecraft made a flyby, coming within 355 kilometres of the surface. Since the encounter, scientists have been exploring the images and have identified regions where brine may have bubbled to the surface. Other images revealed possible, previously unidentified steep-walled depressions up to 50km wide, this could be caused by a free-floating ocean! 

Juno was launched to Jupiter on 5 August 2011. It took off from the Cape Canaveral site on board an Atlas V rocket and travelled around 3 billion kilometres. It arrived at Jupiter on 4 July 2016 and in September 2022 made its closest flyby of Europa. The frozen world is the second of the four Galilean satellites that were discovered by Galileo over 400 years ago. Visible in small telescopes, the true nature of the moon is only detectable by visiting craft like Juno.

During its close fly-by, one of the onboard cameras known as Juno-Cam took the highest resolution images of the moon since Galileo took a flyby in 2000. The images supported the long held theory that the icy crusts at the north and south poles are not where they used to be. Another instrument on board, known as the Stellar Reference Unit (SRU), revealed possible activity resembling plumes where brine may have bubbled to the surface.

The ground track over Europa that was followed by Juno enabled imaging around the equatorial regions. The images revealed the usual, expected blocks of ice, walls, ridges and scarps but also found something else. Steep walled depressions that measured 20 to 50 kilometres across were also seen and they resembled large ovoid pits.

The observations of the meanderings of the north/south polar ice and the varied surface features all point towards an outer icy shell that is free-floating upon the sub surface ocean. This can only happen if the outer shell is not connected to the rocky interior. When this happens, there are high levels of stress on the ice which then causes the fracture pattern witnessed. The images represent the first time such patterns have been seen in the southern hemisphere, the first evidence of true polar wandering.

The images from the SRU surprisingly provided the best quality images. It was originally designed to detect faint light from stars for navigation. Instead, the team used it to capture images when Europa was illuminated by the gentle glow of sunlight reflected from Jupiter. It was quite a novel approach and allowed complex features to become far more pronounced than before. Intricate networks of ridges criss-crossing the surface were identified along with dark stains from water plumes. One feature in particular stood out, nicknamed ‘the Platypus’, it was a 37 kilometre by 67 kilometre region shaped somewhat like a platypus.
