Space agency tasked with establishing Coordinated Lunar Time, partly to aid missions requiring extreme precisionThe White House wants Nasa to figure out how to tell time on the moon.A memo sent Tuesday from the head of the US Office of Science and Technology Policy (OSTP) has asked the space agency to work with other US agencies and international agencies to establish a moon-centric time...

First attempt with private Kairos rocket was intended to test viability of homegrown commercial launch businessA rocket made by a Japanese company has exploded seconds after it was launched with the goal of putting a satellite into orbit.Tokyo-based Space One’s 18-metre Kairos rocket blasted off from the company’s launch pad in the Wakayama region of western Japan, carrying a small government test satellite, on...

Exclusive: Paper by UCL professor says ‘wobbly’ space-time could instead explain expansion of universe and galactic rotationDark matter is supposed to account for 85% of the mass in the universe, according to conventional scientific wisdom. But proponents of a radical new theory of gravity, in which space-time is “wobbly”, say their approach could render the elusive substance obsolete.The proposition, outlined in a new paper,...

Exclusive: Significant discovery, made by James Webb telescope, provokes disagreement over conditions on planet’s surfaceAstronomers have observed a distant planet that could be entirely covered in a deep water ocean, in findings that advance the search for habitable conditions beyond Earth.The observations, by Nasa’s James Webb space telescope (JWST), revealed water vapour and chemical signatures of methane and carbon dioxide in the atmosphere of...

Intuitive Machines, private company behind lander, says mission will end after five days rather than the expected to seven to 10Flight control engineers expect to lose contact with the private US moon lander Odysseus on Tuesday, cutting short the mission five days after its sideways touchdown, the company behind the spacecraft, Intuitive Machines, said.It remained to be seen how much scientific data might be...

Unmanned Slim spacecraft responds to signal from Earth after touching down at awkward angle in JanuaryJapan’s moon lander has responded to a signal from Earth, suggesting it survived the two-week lunar night, the country’s space agency has said.The unmanned Smart Lander for Investigating Moon (Slim) touched down last month at a wonky angle that left its solar panels facing the wrong way. But as...

The environmentally friendly LignoSat probe – set to orbit this summer – has been created to combat harmful aluminium particlesJapanese scientists have created one of the world’s most unusual spacecraft – a tiny satellite that is made of timber.The LignoSat probe has been built of magnolia wood, which, in experiments carried out on the International Space Station (ISS), was found to be particularly stable...

Space agency announces ‘successful liftoff’ and says rocket has already released one micro-satelliteJapan’s space agency has successfully launched a second test model of its new flagship rocket H3, in a welcome boost to its space program after last year’s inaugural flight failed.The launch further burnishes the country’s space credentials after the historic “pinpoint” moon landing of Japan’s Slim spacecraft last month.

Slim spacecraft landed on the moon and is communicating with earth but is not generating electricityJapan’s Slim spacecraft lands on moon but struggles to generate power(I’m really enjoying the soft piano music being played in the background of this Japanese space agency live feed. Very calming in a tense situation!)The probe is now “scanning the surface” and looking for a place to land, space...

In launch event on Friday, agency shared plans to test over US cities to see if it’s quiet enough by engaging ‘the people below’Nasa has unveiled a one-of-a-kind quiet supersonic aircraft as part of the US space agency’s mission to make commercial supersonic flight possible.In a joint ceremony with Lockheed Martin Skunk Works in Palmdale, California, on Friday, Nasa revealed the X-59, an experimental...

After four-month journey, Aditya-L1 will measure and observe sun’s outermost layersIndia’s solar observation mission has entered the sun’s orbit after a four-month journey, the latest success for the space exploration ambitions of the world’s most populous country.The Aditya-L1 mission was launched in September and is carrying an array of instruments to measure and observe the sun’s outermost layers.
