🗞️ Driving the news: On April 14, Blue Origin’s New Shepard carried an all-women crew—including pop star Katy Perry and philanthropist Lauren Sánchez—on an 11-minute suborbital spaceflight
• While the mission is symbolically significant, questions remain about the environmental sustainability of space tourism, even when powered by reusable rocket systems
🔭 The context: Named after astronaut Alan Shepard, New Shepard is a reusable suborbital rocket system developed by Jeff Bezos’ Blue Origin
• It uses a liquid hydrogen and oxygen-fueled engine, which emits only water vapor during flight. Nearly 99% of the rocket's dry mass is reused
• The mission also marks a notable cultural milestone, as it's the first all-women spaceflight crew since 1963
🌍 Why it matters for the planet: Despite lower direct emissions, suborbital launches still release particles like soot into the upper atmosphere, where their warming effects are significantly amplified—up to 500 times greater than at ground level
• The expansion of space tourism raises concerns about its cumulative environmental footprint, particularly as flights become more frequent
• However, advances in reusable rocket systems like New Shepard offer a path to reduce material waste and promote circularity in aerospace
⏭️ What's next: As private spaceflight accelerates, its environmental regulation remains limited
• With ticket prices in the hundreds of thousands, critics argue space tourism remains an exclusive venture with questionable climate trade-offs
• Future assessments will likely focus on lifecycle emissions, atmospheric impacts, and the role of commercial space in advancing sustainable innovation versus spectacle
💬 One quote: “This opportunity is so incredible — so that I can show all of the youngest & most vulnerable among us to reach for the stars, literally and figuratively,” - Katy Perry, highlighting the mission’s inspirational intent
📈 One stat: According to a 2022 UCL study, soot released by rockets in the upper atmosphere has a warming effect 500 times greater than if released by aircraft at lower altitudes
