How High Did Blue Origin New Shepard Really Go?
Blue Origin launched its New Shepard suborbital rocket system into space on April 14th carrying a famous group of passengers into space. In the aftermath of the flight, there has been celebration, criticism and everything in between. As a former NASA scientist, I will leave that banter for other formats and stick to a science question that some of you may be curious about. How high did the Blue Origin NS-31 mission actually go, and did they really make it to space?

For the answers, I will turn to the pioneers of U.S. space travel, NASA. The flight aboard the autonomous, reusable rocket named for Alan Shepard, the first American in space, lasted 11 minutes. It is reported that the rocket system ascended to an altitude of roughly 66 miles. According to the NASA Jet Propulsion Laboratory website, '…. the edge of space – or the point where we consider spacecraft and astronauts to have entered space, known as the Von Karman Line – is only 62 miles (100 kilometers) above sea level.'
By that definition, NS-31 definitely reached space, but how does it compare to other things in space? As an atmospheric scientist, I thought it would be interesting to frame the discussion in terms of the atmospheric layers. Most of us will never leave the troposphere. They zipped through the stratosphere and into the mesosphere.
Layers of the atmosphere.
My friend and colleague Dr. Kathryn Sullivan flew on three Space Shuttle missions and became the first American woman to walk in space. She went on to serve as the NOAA Administrator and became the first woman to dive to the Mariana Trench, the lowest point on Earth. The Space Transportation System or Space Shuttle was designed to operate between about 120 to 600 miles. However, its highest altitude achieved was an altitude of roughly 386 miles when it released the Hubble Space Telescope in 1990.
Kathryn Sullivan was the first American woman to walk in space.
Other reference points that may be familiar to you include the International Space Station, which is in a low Earth orbit that can vary between 200 to 250 nautical miles. The Moon is a little over 238,000 miles from Earth, and the Sun is 93 million miles from Earth.
The Blue Origin mission barely breached the threshold for space, but they did it. The mission probably has garnered more media attention this week than many of NASA's 135 Space Shuttle missions between 1981 and 2011. Those historic missions and the pioneers associated with them should not be forgotten. This point may is likely the source of some of the cynism out there. NASA and other space-faring organizations have never stopped exploring space, studying Earth, and advancing technology. They continue to blaze trails. Others have joined the journey too.
FORT WORTH, TEXAS - APRIL 8: The moon begins to eclipse the sun on April 8, 2024 in Fort Worth, ... More Texas. Millions of people have flocked to areas across North America that are in the "path of totality" in order to experience a total solar eclipse. During the event, the moon will pass in between the sun and the Earth, appearing to block the sun. (Photo by)
However, this Blue Origin moment should not be dismissed. If anything, it has science, technology, engineering, and mathematics in your newsfeed. STEM is critical to our lives, so I cannot hate on any opportunity to celebrate it or expose it. I do have one request though. Let's celebrate the scientists, engineers, programmers, and other key personnel too.

Amazon's Kuiper satellites to get boost from rival SpaceX
Amazon's race to challenge SpaceX in orbit is getting a helping hand from its chief competitor: SpaceX itself, which will launch the next batch of Amazon's Project Kuiper internet satellites skyward on Wednesday. A flock of 24 Kuiper internet satellites will ride aboard a SpaceX Falcon 9 rocket before dawn. The mission, dubbed KF-01, has a 27-minute launch window that opens at 2:18 AM ET and will lift off from Cape Canaveral Space Force Station. Once complete, it will bring the total number of Kuiper satellites on orbit to 78. Amazon ultimately plans to deploy more than 3,200 spacecraft in its first generation constellation in low Earth orbit, aiming to stake a serious claim in the satellite internet market — a market that is currently dominated by SpaceX's Starlink's network of roughly 8,000 satellites. While Kuiper and SpaceX may make for strange bedfellows, Jeff Bezos' Amazon inked a three-launch deal with SpaceX back in December 2023. That agreement came scarcely two months after the e-commerce giant faced a lawsuit from shareholders over an earlier decision not to consider SpaceX when it doled out its first round of lucrative launch contracts, even though the Falcon 9 is the most reliable rocket flying today. The catch is, at least half of Kuiper's initial constellation must be deployed by by the end of July 2026, per its license from the U.S. Federal Communications Commission. The clock is ticking: among the other selected launch providers — United Launch Alliance (ULA), Arianespace, and Blue Origin — only ULA has an operational rocket available to carry satellites to orbit. ULA launched the first two batches of Kuiper satellites; the first batch launched in April. Blue Origin, Bezos' other company, will eventually carry Kuiper satellites on its massive New Glenn rocket, but it has only flown once so far, and it did not manage to recover the booster. The second launch is currently scheduled for August 15.

These 4 Exercises May Be Key to a Good Night's Sleep
When you're exhausted, starting a new exercise routine may sound like a nightmare, but a new study suggests getting active could be the secret to a good night's sleep. Scientists in China reviewed existing clinical trial data and found that certain forms of exercise, including yoga and jogging, that appeared to help people sleep longer at night. The findings suggest physical activity should be considered as a frontline treatment for insomnia, the researchers said. 'The most important takeaway from this research is that we can confidently tell people with insomnia, 'Exercise really can help you sleep better,'' lead study author Zhi-jun Bu told Gizmodo. Bu and his colleagues were inspired by the idea of 'green prescriptions,' which are essentially interventions for physical and mental health that involve exercise or nutrition. They focused on insomnia because it's both common and debilitating. More than half of American adults are believed to have experienced difficulty sleeping, while a recent survey from the American Academy of Sleep Medicine found that 12% of U.S. adults have been diagnosed with chronic insomnia. Eating Dairy Before Bed Can Give You Nightmares, Study Suggests The researchers analyzed data from 22 clinical trials involving more than 1,300 participants and 13 different interventions for insomnia, including cognitive-behavioral therapy, seven forms of exercise, and so-called active controls, like stretching or being given lifestyle advice. As the researchers had expected, people who received CBT saw significant improvements in their sleep quality and duration, as did those who practiced Tai Chi, yoga, and walking or jogging. Of these, yoga was linked to almost two hours of extra sleep compared to controls, while walking or jogging was tied to a significant reduction in the severity of people's self-reported symptoms. And Tai Chi apparently provided the most benefits for sleep of all the exercises tested. The findings were published Tuesday in the journal BMJ Evidence-Based Medicine. Bu conducted the study while a researcher at the Beijing University of Chinese Medicine's Center for Evidence-Based Chinese Medicine; he's now pursuing a doctorate at The Affiliated Hospital and Clinical Medical College of Nanjing University of Chinese Medicine. The analysis is promising, but it has limitations. Some of the trials included were of lower quality than others. But there is other evidence to suggest that exercise can promote rest; a study published earlier this month found that daily exercise was associated with deeper, more restorative sleep. It's also unclear why physical activity can help us doze off, but the researchers have some theories. 'Yoga incorporates breath control and meditation, which helps regulate the autonomic nervous system and reduce anxiety and stress. Tai Chi, as a mind-body practice combining physical movement and mental focus, may enhance parasympathetic activity, reduce inflammatory responses, and promote brain plasticity and circadian rhythm regulation,' Bu explained. 'Aerobic exercises such as walking or jogging may improve sleep structure by increasing energy expenditure, enhancing melatonin secretion, lowering cortisol levels, and boosting the proportion of deep sleep,' he added. Barely Sleep and Still Feel Fine? Thank Your Lucky Genes Other questions remain unanswered: There's no established optimal 'dose' of physical activity for insomnia, and the timing of our exercise could be crucial, too. A study published in April found that performing intense workouts up to four hours before bed could disrupt sleep, for example. Some individuals might also benefit most from specific forms of exercise. Yoga and Tai Chi might be best for people who don't sleep enough, while aerobic exercise might work best to reduce people's daytime sleepiness and fatigue, Bu said. 'Overall, exercise is a natural sleep aid with low side effects, low costs, and high accessibility, making it especially suitable for promotion in primary healthcare and community health settings,' Bu said.
