NASA Tests Water Powered Spacecraft in Orbit

Picture two tissue box-sized spacecraft orbiting Earth.

Then picture them communicating, and using a water-powered thruster to approach each other. If you can do that, then you’re up to speed on one of the activities of NASA’s Small Spacecraft Technology Program (SSTP.) It’s all part of NASA’s effort to develop small spacecraft to serve their space exploration, science, space operations, and aeronautics endeavors.

Where you can travel in space depends on how much propellant you’ve got on board your rocket and how efficiently you can use it. But there’s a source of free propellant right here in the Solar System – the Sun – which is streaming out photons in all directions. You just need to catch them.

And right now, the Planetary Society’s new LightSail 2 spacecraft is testing out just how well it’ll work.

The Lunar Gateway Will be in a “Near-Rectilinear Halo Orbit”

After months of discussion, the space agencies behind the Lunar Gateway have decided how the space station will orbit the Moon. NASA and the ESA are developing the Lunar Gateway jointly, and the orbital path that it will follow around the Moon is a key part of mission design. It’ll affect all the vital aspects of the mission, including how spacecraft will rendezvous and land at the station.

SpaceIL Scraps its Plans to go Back to the Moon. Instead, it’s Got a New Secret “Significant Objective” for Beresheet 2

Mystery. Secrecy. A Need-To-Know Basis. These are the hallmarks of science. Wait a minute: no they’re not. So what’s with all the mysterious secret objective talk from SpaceIL about Beresheet2?

The Blue Origins Founder Wants to Get to the Moon by 2024

Blue Origin is going to the Moon. In an hour-long presentation in Washington DC on May 9th, Jeff Bezos spelled out his plans for reaching the Moon, confirming what many guessed he was hinting at in a tweet from the previous week.

Bezos and his company, Blue Origin, are developing a lunar lander capable of landing a large payload of 6.5 metric tons (14,330 lbs.) on the lunar surface. The lander is being called ‘Blue Moon’ and the target date for its rendezvous with the Moon is 2024.

Voyager and Pioneer’s Grand Tour of the Milky Way

During the early 1990s, NASA’s Pioneer 10 and 11 probes became the first robotic missions to venture beyond Neptune. In 2012 and 2018, the Voyager 1 and 2 missions went even farther by crossing the heliopause and entering interstellar space. Eventually, these probes may reach another star system, where their special cargo (the Pioneer Plaques and the Golden Records) could find their way into the hands of another species.

Which raises an important question: where might these spacecraft eventually wander? To address this, Coryn Bailer-Jones of the Max Planck Institute for Astronomy and Davide Farnocchia of NASA’s Jet Propulsion Laboratory recently conducted a study that examined which star systems the Voyager and Pioneer probes will likely encounter as they drift through the Milky Way over the next few million years…

Beresheet Crashed.

The Israeli Beresheet spacecraft has crashed into the Moon. The craft, whose name is Hebrew for “in the beginning” made its descent to the Moon but failed to stick its landing. If it had been successful, it would have put Israel in elite company, and made them only the fourth country to have a soft landing on the Moon, joining the USA, China, and the former Soviet Union.

Using Black Holes to Conquer Space: The Halo Drive!

The idea of one day traveling to another star system and seeing what is there has been the fevered dream of people long before the first rockets and astronauts were sent to space. But despite all the progress we have made since the beginning of the Space Age, interstellar travel remains just that – a fevered dream. While theoretical concepts have been proposed, the issues of cost, travel time and fuel remain highly problematic.

A lot of hopes currently hinge on the use of directed energy and lightsails to push tiny spacecrafts to relativistic speeds. But what if there was a way to make larger spacecraft fast enough to conduct interstellar voyages? According to Prof. David Kipping – the leader of Columbia University’s Cool Worlds lab – future spacecraft could rely on a Halo Drive, which uses the gravitational force of a black hole to reach incredible speeds.

A few hours ago, the SpaceX Crew Dragon splashed down in the Atlantic Ocean, about 200 miles off the coast of Florida. The splashdown is the last act in what has been a successful first flight for the Crew Dragon. The flight, called Demo-1, was launched on March 2nd and spent five days at the International Space Station (ISS).
