NASA will be broadcasting a live stream of a spacewalk on Friday, April 17th, to upgrade the power system on the International Space Station. Astronauts Shane Kimbrough and Peggy Whitson will be performing the spacewalk, which is expected to last about 6.5 hours. During the spacewalk, the astronauts will be replacing a failed voltage regulator with a new one, as well as installing a new adapter plate and cable routing assembly. The spacewalk will be broadcast live on NASA TV, and viewers can follow along as the astronauts complete their tasks. This is an exciting opportunity to witness a unique event in space exploration, and to learn more about the work that goes into maintaining the International Space Station.

The NASA Reaches Maximum Utilization of Space Station is a program designed to maximize the use of the International Space Station (ISS) for scientific research and exploration. The program includes the development of new technologies, the expansion of existing capabilities, and the utilization of the ISS as a platform for commercial activities. The program also seeks to increase the number of astronauts and cosmonauts aboard the station, as well as to increase the number of experiments conducted on the station. The program is part of NASA's overall mission to explore and expand our knowledge of space.

This revolutionary new technology uses graphene to construct a tractor beam, which is a device that can manipulate objects from a distance. The graphene-based tractor beam works by creating an acoustic wave that can be used to move objects in three dimensions. This technology has the potential to revolutionize the way we interact with our environment, allowing us to manipulate objects without having to physically touch them. It could also be used for medical applications, such as manipulating cells or tissues without damaging them. This technology is still in its early stages, but it has the potential to revolutionize the way we interact with our environment.
