NASA adopting Apollo's urgency to build a moon base and land astronauts within two years
NASA plans to return astronauts to the moon with the Artemis III mission set for next summer. Following that, Artemis IV aims to accomplish a historic moon landing by 2028, marking the first since the Apollo missions. Administrator Jared Isaacman emphasized the importance of efficiency and a fast-paced approach similar to Apollo's playbook. Docking exercises with SpaceX and Blue Origin's landers will occur before the moon base establishment.
A $5 nut doomed SpaceX’s first rocket; its satellite crashed through a shed roof and landed beside its own shipping crate
In March 2006, SpaceX’s first rocket failed because of a $5 aluminium nut that cracked from corrosion. The cadet-built satellite on board was thrown clear and landed in a storage shed beside its own shipping crate. Reports first blamed human error, but a review board pointed to corrosion, a cause even Elon Musk called only “most probable”.

This partnership builds on decades of collaboration between the two nations.
In 1981, two satellites were launched by NASA to study the interactions between Earth's magnetosphere and ionosphere
In 1981, two satellites were launched by NASA to study the interactions between Earth's magnetosphere and ionosphere. The Dynamics Explorer mission used two spacecraft, DE-1 and DE-2, to study space plasma, electric currents and energy flow. Both satellites launched together and followed polar orbits. DE-1 operated at higher altitudes, while DE-2 studied the region closer to Earth before re-entering the atmosphere in 1983.
In 2006, NASA and French Space Agency CNES launched a satellite in a joint mission to probe the properties of Earth's thin clouds and aerosols
In 2006, NASA and French Space Agency CNES launched a satellite in a joint mission to probe the properties of Earth's thin clouds and aerosols. CALIPSO studied clouds and airborne particles from orbit. Its data helped scientists understand climate, weather and air quality, while its observations improved atmospheric models and satellite weather measurements.
From Thumba to tomorrow: Indian space programme is preparing for its biggest leap yet
India's space program began with a small rocket range in 1962. It progressed to launching its first satellite and developing indigenous launch vehicles. Chandrayaan-3's lunar landing marked a significant achievement for the nation. The program now includes private sector involvement and ambitious future goals. India aims for a space station by 2035 and a lunar landing by 2040.
Space start-up OrbitAid to demonstrate in-orbit re-fuelling tech for satellites
An Indian space startup, OrbitAid Aerospace, is preparing to launch AyulSAT, a satellite designed for in-orbit refueling. This technology aims to extend the lifespan of satellites and reduce space debris. India will become the fourth nation to showcase this capability. The mission lays the groundwork for an orbital economy focused on servicing and sustaining satellites.
Elon Musk's SpaceX to launch 400+ satellites in bold push to transform Alaska’s internet connectivity
SpaceX successfully launched 24 new Starlink satellites from California, boosting its orbital network to over 7,900.
