One spacecraft could visit all of Saturn's inner large moons
Wednesday, 31 May 2023 19:18
If you've ever played Kerbal Space Program, you know how difficult it can be to get your spacecraft into the orbit you want. It's even more difficult in real life. This is why it's pretty impressive to see a proposal to study all of Saturn's large inner moons in one go.
At a broad level, orbits are pretty simple. Planets and moons are basically ellipses. Once set into motion, spacecraft generally follow an elliptical or parabolic path, so it's just a matter of lining up your spacecraft's orbit with your destination and point of origin. You can do the calculations by hand if you know the math.
Cutting-Edge Reconnaissance Satellites: Revolutionizing National Security from Space

NASA talks UFOs with public ahead of final report on unidentified flying objects
Wednesday, 31 May 2023 15:28
NASA held its first public meeting on UFOs Wednesday a year after launching a study into unexplained sightings.
The space agency televised the hourslong hearing featuring an independent panel of experts. The team includes 16 scientists and other experts selected by NASA including retired astronaut Scott Kelly, the first American to spend nearly a year in space.
Several committee members have been subjected to "online abuse" for serving on the team, which detracts from the scientific process, said NASA's Dan Evans, adding that NASA security is dealing with it.
How much damage will lunar landings do to lunar orbiters?
Wednesday, 31 May 2023 15:01
Multiple missions are destined for the moon in this decade. These include robotic and crewed missions conducted by space agencies, commercial space entities, and non-profit organizations. The risks and hazards of going to the moon are well-documented, thanks to Apollo Program and the six crewed missions it sent to the lunar surface between 1969 and 1972. But unlike the "footprints and flags" of yesterday, the plan for the coming decade is to create a "sustained program of lunar exploration and development."
This means establishing a greater presence on the moon, building infrastructure (like habitats, power systems, and landing pads), and missions regularly coming and going. Given the low-gravity environment on the moon, spacecraft kick up a lot of lunar regolith (aka.
Metal fuel for carbon-free energy on Earth… and the Moon

Everything burns. Given the right environment, all matter can burn by adding oxygen, but finding the right mix and generating enough heat makes some materials combust more easily than others. Researchers interested in knowing more about a type of fire called discrete burning used ESA’s microgravity experiment facilities to investigate.
