What methods can be employed to send a spacecraft to Uranus despite the former’s immense distance from Earth? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of scientists investigated ways to cut the travel time to the second most distant planet from the Sun. This study has the potential to help scientists, engineers, and mission planners develop low-cost and novel techniques for deep space travel while conducting cutting-edge science.
How can nanosatellites help advance lunar exploration and settlement? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers from Grahaa Space in India investigated the pros, cons, and applications for using nanosatellites on the Moon. This study has the potential to help scientists, engineers, mission planners, and future lunar astronauts develop and test new technologies for advancing lunar exploration, and possibly beyond the Moon.
What are the best methods to explore Valles Marineris on Mars, which is the largest canyon in the solar system? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers investigated how helicopters could be used to explore Valles Marineris, which could offer insights into Mars’ chaotic past. This study has the potential to help scientists and engineers develop new methods for studying Mars’s history and whether the Red Planet once had life as we know it.
Astronomers Observe Dark Matter Bridge in the Perseus Cluster
Space exploration not only allows us to look out into the universe but it also allows us to look back at Earth. ESA’s Biomass satellite will measure the amount of carbon in the world's forests, tracking how the carbon cycle absorbs and releases carbon over the seasonal cycles. It launched this week from the Kourou Spaceport in French Guiana atop a Vega-C rocket and safely reached its intended orbit. It has a synthetic aperture radar that can penetrate forest canopies like an infrared telescope can peer through dark dust clouds.
The James Webb Space Telescope has a number of science goals. One of them is to help understand the evolution of galaxies and their formation within the first billion years after the Big Bang. Astronomers have completed an initial Webb telescope survey that discovered 1,700 galaxy groups. Many of these groups date back to when the Universe was less than 1 billion years old. The survey spans 12 billion years of cosmic history, from these ancient formations to the present day.
Space-based solar power (SBSP) has long been the dream of many space enthusiasts and energy economists. However, the reality of economic constraints has long left any practice projects on the ground. There has been plenty of discussion about how to lower the cost of entry to build the kind of space-based solar power satellite described by John Mankins in his books and articles. However, even with the advent of lower costs to orbit thanks to reusable rockets, the economic case for SBSP is still not great simply due to the sheer amount of mass required to get into orbit. Unless we get that mass from somewhere else, with a smaller gravity well. Astrostrom, which means something like "Star current" in German, is an organization based in Switzerland that hopes to make space-based solar power a reality.
Astronomy has entered the age of gravitational waves. While there are plenty of differences between gravitational wave astronomy and typical waves of the electromagnetic spectrum, they share one similar feature: frequency. While we have detectors for a wide range of electromagnetic frequencies, gravitational wave detectors only focus on a narrow band of relatively low-frequency signals. That will change with the upgrade of the GEO600 gravitational wave detector located at the Max Planck Institute for Gravitational Physics.
