NASA's Twin Spacecraft Will Execute Powered Slingshot Maneuvers on Their Way to Mars

NASA's twin spacecraft, ESCAPADE, will perform powered slingshot maneuvers above Earth on their way to Mars. The spacecraft, named Red and Blue, will measure how the solar wind interacts with remnants of Mars' ancient magnetic field. They will use thrusters to boost their speed, combining Earth's gravity with their maneuvers. The first spacecraft will do so on November 7th, and the second on November 9th. These maneuvers will increase their speed from 10.14 km/s to 10.78 km/s, an increase of over 2,000 km/hour. The slingshots are necessary because ESCAPADE didn't launch in the usual Mars launch window. The spacecraft will fly through Earth's magnetotail, making them the first to do so.

• ESCAPADE is composed of two spacecraft, Red and Blue, which will fly in formation to eliminate uncertainty about solar wind interactions.
• The spacecraft will perform trans-Mars injection burns, using thrusters to boost speed and take advantage of Earth's gravity.
• The first burn will occur on November 7th, and the second on November 9th.
• The spacecraft will be visible to some observers on the ground, appearing as a pair of dim, refrigerator-sized objects moving against the starry background.

The mission aims to understand how Mars lost its atmosphere and became cold and dead. The data from ESCAPADE will help scientists study the effects of solar wind on Mars' magnetic field and how the planet's magnetic field has changed over time. The mission is a critical step in understanding planetary evolution and the potential for life on other planets.
