US space agency NASA announced it is partnering with the Pentagon’s DARPA to develop and test a nuclear-powered rocket engine to send astronauts on future missions to Mars. But some experts remain sceptical.
The LauncherOne rocket, which was launched as part of the UK’s first-ever rocket mission, fails to reach orbit following an "anomaly", organisers say.
The comet is a rare visitor. The last time it passed Earth was during the Upper Paleolithic period when Neanderthals still roamed Earth.
The telescope "will be one of humanity's biggest-ever scientific endeavours", says SKA Observatory's Director-General Philip Diamond.
Shenzhou-15 was the last of 11 missions that began in April 2021 with an aim to assemble the "Celestial Palace" – the second inhabited outpost in low-earth orbit after the NASA-led International Space Station.
The rocket has been named after Vikram Sarabhai, the pioneer of India's space programme.
Dubbed Artemis I, the mission brings the US a big step closer to putting astronauts back on the lunar surface for the first time since the end of the Apollo programme 50 years ago.
Iranian state TV reported that the carrier would be able to put a satellite weighing 80 kg into orbit some 500 kilometres from Earth.
The larger of the two strikes churned out boulder-size slabs of ice, which may help researchers look for ways future astronauts can tap into Mars' natural resources, scientists say.
Burst of gamma-rays -- the most intense form of electromagnetic radiation -- was first detected by orbiting telescopes on October 9, and its afterglow is still being watched by scientists across the world.
It was Japan's first failed launch in nearly two decades, and the only one for an Epsilon rocket, a solid-fuel model that has flown five successful missions since its 2013 debut.
NASA says it succeeded in deflecting an asteroid in a historic test of humanity's ability to stop an incoming cosmic object from devastating life on Earth.
