![]() Her latest book, " Why Am I Taller?", is co-written with astronaut Dave Williams. Elizabeth's reporting includes multiple exclusives with the White House and Office of the Vice-President of the United States, an exclusive conversation with aspiring space tourist (and NSYNC bassist) Lance Bass, speaking several times with the International Space Station, witnessing five human spaceflight launches on two continents, flying parabolic, working inside a spacesuit, and participating in a simulated Mars mission. She was contributing writer for for 10 years before joining full-time. Įlizabeth Howell (she/her), Ph.D., is a staff writer in the spaceflight channel since 2022 covering diversity, education and gaming as well. If funded, the mission would launch to space around 2025.įollow Elizabeth Howell. ![]() ![]() It would orbit Jupiter and get more information about Europa's ocean in a series of flybys. The cycling of material between the ocean and ice shell could potentially provide sources of chemical energy that could sustain simple life forms."Īmong NASA's proposed missions to Jupiter's icy moon is the Europa Clipper, a mission pegged to cost about $2 billion. "The Galileo mission found strong evidence that a subsurface ocean of salty water is in contact with a rocky seafloor. "Hidden beneath Europa's icy surface is perhaps the most promising place in our solar system beyond Earth to look for present-day environments that are suitable for life," NASA officials wrote in a statement. These interactions could potentially create the energy necessary for life, providing that the building blocks – such as amino acids – are available, scientists have said. That flexing not only creates energy, but can grind the water of the moon against rocks. Calculations of tidal flexing make it possible for moons and planets to host liquid water even if they are far from a star's traditional "Goldilocks zone," the area surrounding a star where heat and energy allow water to remain liquid on a planet.
