Trojans

 A new study by the SETI Institute suggests two worlds will only rarely share the same orbit.

Of course, that happens in our neighborhood with planets and asteroids.  Those asteroids are called Trojans.

Mining

 Mining in space, if all goes well, will be a major driver of civilization at some point.

Currently, however, there are technological, legal, and economic hurdles to overcome.

Monkeys

 On this date in 1959, two monkeys survived a short spaceflight.

It was a crucial step toward human spaceflight.

Asteroid

 A mile-wide asteroid just flew past Earth.

Had it hit, it would have caused immense damage on a regional scale.

Energy

 A new study by physicists argues we need to quickly embrace nuclear energy and renewables or risk societal collapse.

If we do, the study predicts we could be a true interplanetary species within 200 years.

Interstellar Meteorte

 Avi Loeb and Amir Siraj of Harvard have determined that a meteorite that landed in Papua New Guinea in 2014 was an interstellar object.

It was also metallic, which is interesting.

Carpenter

 On this date in 1962, Scott Carpenter became the second American to orbit Earth/

It was his only space flight.

Galaxies

 Astronomers have found a spray of stars linking two galaxies.

That would make inter-galactic travel more feasible.

UFO

 According to Michio Kaku, the Pentagon now has 400 reports of UFO incidents.

In last year's report to Congress. it listed 144, of which 143 were unexplained.

Fermi

 Scientists are still struggling with the Fermi Paradox-- if there are other civilizations in the universe, why aren't they here?  A new study suggests civilizations reach a  crisis point where they either stop expanding or collapse.

Maybe scientists still concerned with this question should first tall to MUFON and the Pentagon.

Starliner

 NASA is set to launch the Bowing Starliner on a second uncrewed test flight.

The first one didn't go especially well.

Mars

 This year's Humans to Mars Summit is underway in Washington, DC.

This one expects to focus on international relations.

UFO

 Congress is holding public hearings on UFOs today.

It's the first such proceeding in fifty years.

Ingenuity

 Ingenuity suffered a communications glitch recently.

JPL says it was due to dust in the Martian atmosphere.

Amalthea

 Amalthea is a moon of Jupiter-- the largest of the swarm of tiny moons after the Galileans.

It orbits at about half the Earth-Luna distance and completes one orbit in roughly 12 hours.

NOMAD

 DARPA. the Pentagon's high tech agency, is studying ways to build large structures in space.

The program is called NOMAD.

Water

 Scientists using data from China's rover argue there may have been large amounts of water on Mars much more recently than previously thought.

Mars could have had substantial quantities of water 700 million years ago, according to the study.

Space Solar Power

 The UK is studying space solar power as a way to meet greenhouse gas emission goals by 2050.

It could have a demonstrator in orbit by 2035.

Starlink

 The head of the Russian space agency has threatened Elon Musk.

Russia objects to Musk's Starlink satellite network, which is giving Ukraine Internet access/

Young Worlds

 Some scientists say for a rocky world to support life it must be young.

Young rocky worlds are geologically active,which generates the energy and complex chemistry required for life.

NoKo

 North Korea recently launched a ballistic missile from a submarine.

It was the latest in a series of test flights.

Crew-3

 Crew-3 astronauts safely returned home yesterday.

They spent 6 months on ISS.

Exploring Luna

 Chinese scientists think lunar explores will be able to get oxygen and fuel from lunar rocks.

That'd be a big plus.

Canada

 Canada is considering extending its criminal jurisdiction to the Moon and in-space facilities.

It would apply only to crimes allegedly committed by Canadian citizens.

Tiangong

 China plans six missions to its Tiangong space station this year.

It also plans to expand Tiangong and invite commercial activity.

SpaceForge

 Welsh startup SpaceForge argues the ultimate answer to climate change is to put manufacturing into space.

Its first experiment is planned to launch this year.
