Get ready for a thrilling journey as NASA's Escapade mission takes center stage! This groundbreaking endeavor, a collaborative effort between NASA, Blue Origin, and UC Berkeley, promises to unveil the mysteries of Mars' atmosphere. But here's the catch: sending anything to Mars is no easy feat, as history has shown us.
The Soviet Union's early attempts in the 1960s ended in failure, and even the US struggled with quick flybys. It wasn't until 1971 that the Mariner 9 mission successfully orbited another planet, breaking the losing streak. Fast forward to today, and Mars remains a challenging destination, with only a handful of functional orbiters and rovers, mostly operated by NASA.
On Sunday, NASA's Escapade mission will launch, aiming to add two more orbiters to the exclusive club of successful Mars missions. This mission is a game-changer, not just for its scientific goals but also for the stories it tells.
New Glenn's Debut: NASA has chosen Blue Origin's New Glenn rocket for this mission, marking its official debut. New Glenn, the new kid on the block, will launch Escapade into orbit and return to Earth. Blue Origin's first attempt with New Glenn didn't go as planned, with the rocket's first stage missing its landing target and plunging into the Atlantic, prompting an FAA investigation. All eyes will be on Blue Origin to see if they can nail the landing this time, a crucial step towards becoming a commercial vendor of reusable space launch vehicles, just like Elon Musk's SpaceX.
The Budget Challenge: Escapade's budget is a story in itself. Mars missions are notoriously expensive, with the Mars Exploration Rover mission costing over $1 billion. Escapade, however, had a much tighter budget, part of NASA's Small Innovative Missions for Planetary Exploration (SIMPLEx) program. UC Berkeley and Rocket Lab were allocated $55 million to build two orbiters, a challenging task that Dr. Robert Lillis, associate director for Planetary Science at UC Berkeley, describes as "tough to build robust, well-instrumented interplanetary probes on a low budget."
The Cost of Admission: NASA's goal with Escapade is to reduce the cost of Mars missions, opening up more opportunities for future exploration. The Indian Space Research Organization's successful Mars Orbital Mission in 2013 set a precedent with its $74 million budget, and Escapade aims to match that. If successful, Escapade will be NASA's first low-cost mission to Mars, a significant milestone that could make future missions more frequent and affordable.
Unraveling Mars' Magnetic Mystery: Mars, despite being Earth's close neighbor, still holds many secrets. We know it had water at some point, but solar winds have been stripping away its magnetosphere, making it inhospitable for water to exist. Escapade aims to study Mars' magnetosphere by deploying two orbiters that will follow each other, providing more consistent measurements. Dr. Lillis explains that the magnetosphere on Mars changes rapidly, and waiting for a single orbiter to circle back leaves many changes unmeasured.
"With Escapade, we can measure cause and effect at the same time, the solar wind and upper atmosphere simultaneously. To understand this dynamic system, we need that perspective," says Dr. Lillis.
So, will Escapade's mission be a success? And what will it uncover about Mars' magnetic field and its history? Tune in to the live stream on Sunday at Blue Origin's website to find out!
