NASA’s twin Mars probes, part of the ESCAPADE mission—short for Escape and Plasma Acceleration and Dynamics Explorers—are finally nearing their long-awaited launch after months of uncertainty. Blue Origin has announced that the two spacecraft are now scheduled to blast off on the second-ever flight of the company’s massive partially reusable New Glenn rocket. The current target liftoff window opens no earlier than August 15 at Cape Canaveral Space Force Station in Florida, a bit later than originally planned as the team recently moved the launch back from late spring.

ESCAPADE aims to revolutionize our understanding of Mars by studying its magnetosphere and how the solar wind interacts with the Red Planet’s thin atmosphere. This mission will attempt to unravel why Mars lost most of its atmosphere over time, a process critical to understanding the planet’s past habitability. These two identical probes have faced delays since being pulled from their initial scheduled launch last October after concerns that a postponement in New Glenn’s development might escalate costs significantly. The New Glenn rocket finally made its debut in January, deploying a test payload to Earth orbit, but an attempted booster landing at sea was unsuccessful. Still, with that initial flight complete, Blue Origin is ready to support its first interplanetary payload.

According to Space.com, the newly confirmed August launch window means the ESCAPADE spacecraft will take a more roundabout journey, arriving at Mars in 2027. Their convoluted trajectory provides a unique opportunity: during their initial cruise phase, the probes will operate out near the Sun-Earth Lagrange Point 2, about 3.5 million kilometers from Earth. This is a rarely explored region that hasn’t seen dedicated spacecraft visits since the 1990s Wind mission, promising new insights into solar and interplanetary weather. While this means the spacecraft will spend longer exposed to space radiation, mission engineers assure that this extended transit shouldn’t pose major risks to their structural integrity.

Meanwhile, both the Perseverance and Curiosity rovers continue their science campaigns on Mars’ surface. NASA’s update earlier this month covered new findings on Jezero Crater’s rim, where Perseverance is investigating mysterious spherule formations believed to provide crucial information about the crater’s ancient rock sequences. Curiosity, for its part, is actively exploring the fractured terrain of Mount Sharp, revealing fascinating details about Mars’ geology and past climate.

Listeners, these next weeks promise excitement as the world awaits another milestone in Mars exploration with ESCAPADE’s launch, while the rovers press on with their unprecedented work.
