Rocket Lab is proceeding as planned with its efforts to recover and reuse spent rocket boosters from its Electron launch vehicle, and has completed its first prototype parachute for use in the recovery process. Rocket lab CEO Peter Beck announced last year that it would be aiming for reusability with the first stage of its rocket, using a system that includes the booster re-entering Earth’s atmosphere, then deploying a parachute to slow its descent so that it can be caught mid-air by a helicopter and returned to land.

Already, Rocket Lab has made good progress on its plan, with two tests under its belt of the guided re-entry par tof the process, including a launch in early December 2019, and one just last week. Now, Beck said on Twitter that the company is ready to move on to stage two, which is developing the parachute system that will deploy once the rocket has completed re-entry, to slow its rate of descent. Rocket Lab’s first parachute prototype is ready, Beck says, and the company will start testing it using low-altitude drops, as well as testing the capture process, beginning next week.

SpaceX is already planning the next big test flight of its future Starship rocket out of southern Texas. As early as mid-March, the company is hoping to fly a test version of the vehicle to a super high altitude and then land it upright on solid ground, proving the rocket can be reused and potentially touch down on other worlds.

The upcoming test is detailed in new paperwork SpaceX filed with the Federal Communications Commission, which provides licensing to aerospace companies that are hoping to fly their vehicles to space. Specifically, the FCC allocates which radio frequencies companies can use to communicate with their vehicles during flight.

SpaceX notes in its filing that it wants special authority to communicate with its Starship rocket while the vehicle flies to an altitude of 12.4 miles or 20 kilometers — nearly halfway to the edge of space. Starship would take off from SpaceX’s test facility at Boca Chica, Texas, and the company would attempt to land the vehicle near the launch site using the rocket’s Raptor engines. SpaceX also plans to send data of the vehicle’s trajectory to both the Air Force and NASA.

There’s no two-ways about it, the Universe is an extremely big place! And thanks to the limitations placed upon us by Special Relativity, traveling to even the closest star systems could take millennia. As we addressed in a previous article, the estimated travel time to the nearest star system (Alpha Centauri) could take anywhere from 19,000 to 81,000 years using conventional methods.

For this reason, many theorists have recommended that humanity should rely on generation ships to spread the seed of humanity among the stars. Naturally, such a project presents many challenges, not the least of which is how large a spacecraft would need to be to sustain a multi-generational crew. In a new study, a team of international scientists addressed this very question and determined that a lot of interior space would be needed!

During their yearlong mission in 2012, NASA’s twin GRAIL spacecraft made the most detailed gravitational map of the moon ever created.
