Space.com: The Japan Aerospace Exploration Agency (JAXA) is developing both a new rocket and suborbital point-to-point craft. The rocket will launch either a traditional capsule or a mini-shuttle. Both craft will have the option of carrying three crew members and up to 400 kg of cargo. The capsule design would have two variants, a heavier capsule for landing on the ground and a lighter capsule for landing on water. The capsule design itself will be an evolution of JAXA’s current H-IIB Transfer Vehicle, which has already delivered cargo to the International Space Station. All the crafts will be launched by a new Mitsubishi Heavy Industries rocket, designated H-X. To keep up with suborbital developments in the US, such as Virgin Galactic’s Spaceship Two, JAXA also plans two point-to-point vehicles that would use rockets and ramjets to attain hypersonic launch speeds and hence higher altitudes than those of the competition.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
