To casual observers, landing a rover on Mars can seem kind of like old news, believe it or not. Especially after all of NASA’s successes. But many are likely not aware of the so-called ‘Mars Curse.‘ The fact is, many of the spacecraft that attempt to land there fail and crash.
Next to run the gauntlet of the Mars Curse is NASA’s Perseverance rover. It’ll attempt its long-awaited landing at Jezero Crater on February 18th. The people at NASA have given the Perseverance rover some finely-tuned tools to get it to the Martian surface safely and to beat the Mars curse.

In the coming decades, a number of missions are planned for Mars, which include proposals to send astronauts there for the first time. This presents numerous logistical and technical challenges, ranging from the sheer distance to the need for increased protection against radiation. At the same time, there is also the difficulty of landing on the Red Planet, or what is referred to as the “Mars Curse“.
To complicate matters more, the size and mass of future missions (especially crewed spacecraft) will be beyond the capacity of current entry, descent, and landing (EDL) technology. To address this, a team of aerospace scientists released a study that shows how a trade-off between lower-altitude braking thrust and flight-path angle could allow for heavy missions to safely land on Mars.
