Although many space missions around the world are on hold, work on NASA's next Mars rover Perseverance continues. A small plate was just installed on the back of the rover which shows a diagram of the Sun, Earth, and Mars, along with the words "explore as one" hidden in morse code. Along side this poetic diagram are the names of 11 million people microscopically etched into a chip. The rover will carry a helicopter to the surface of Mars, which recently completed a final spin test of it's rotors. It's critical to avoid delay at this point, because if Percy doesn't launch in July, it will be 18 months before the planets are once again favorably aligned.
As rovers continue to explore Mars, life found 300 feet below the ocean floor raises hopes that the red planet could still harbor life somewhere under its surface.
Elsewhere in the solar system, the European probe BepiColombo will swing by earth on April 10th for a gravity assist to put it on a circuitous trajectory through the inner solar system, eventually ending at Mercury. Its intuitive to think its more difficult to go away from the sun as towards it, but BepiColombo actually "takes more energy to enter orbit around Mercury than it would to get to Pluto" due to the immensity of the sun. Bepi-Colombo, launched in 2018, will require 1 flyby of earth, two of Venus, and 6 of Mercury before finally settling into orbit in 2025. |
