Startup Rocket Lab has joined SpaceX and Blue Origin in the world of rocket recovery, today bringing its Electron booster back down to Earth for the first time ever as part of its landmark “Return to Sender” mission.

Last week, the Earth had its closest shave with an asteroid ever recorded, when a small space rock skimmed just 370 km (230 miles) above the surface. For comparison, that’s closer than the orbit of the International Space Station.

Following the historic Crew-1 launch, which saw four astronauts lifted into space from US soil on the first ever crewed operational flight of a commercial spacecraft, SpaceX’s Crew Dragon has now safely docked with the International Space Station.

Based on isotope analysis of meteorites, scientists at the Lawrence Livermore National Laboratory have determined that our solar system may have formed much faster than previously thought.

The British government has commissioned a new study into building an orbital solar power station by 2050. It will look into space-based systems that use giant solar arrays to generate electricity and beam it to Earth in the form of microwaves.

Asteroid Apophis has attracted its share of attention, with several projected close shaves with Earth in the coming decades. While most have been ruled out, a previously-overlooked factor has opened a small window for a possible collision in 2068.

History was made today as the US, after a nine-year hiatus, returned to regular crewed space flights from American soil to the International Space Station (ISS) with the launch of the SpaceX Crew-1 mission from the Kennedy Space Center in Florida.

A relic of the 1960s Space Race may be paying Earth a brief visit with NASA announcing that a rocket booster from the 1966 Surveyor 2 robotic Moon lander mission is suspected to have returned from deep space and taken up temporary orbit around Earth.

ESA has given the go-ahead for its Atmospheric Remote-sensing Infrared Exoplanet Large-survey (Ariel) mission to progress from the study phase to the implementation phase, with an industrial contractor to build the spacecraft to be chosen in mid-2021.

A short burst of gamma rays 5.47 billion light years from Earth caused by the collision of two neutron stars that put out more energy in a half-second than the Sun could in 10 billion years has revealed the truth about luminous infrared kilonova.

By analyzing data from radar and optical telescopes, scientists have given radar the ability to make observations of meteors that burn up in the Earth's atmosphere that have previously only possible using optical telescopes.

After a long road featuring uncrewed test flights, launchpad explosions, parachute tests and finally crewed test flights, NASA has now officially certified SpaceX’s spacecraft system for transporting humans to the International Space Station (ISS).
