Launch of the final Delta IV Heavy has been delayed until further notice. An issue with a liquid pump in the gaseous nitrogen pipeline, crucial for providing pneumatic pressure to the launch vehicle's systems, led to the postponement. The anomaly prompted a meticulous troubleshooting process by the United Launch Alliance (ULA) team. Work to diagnose and rectify the issue is underway to ens
Blind people can hear and feel April's total solar eclipse with new technology
Minh Ha, assistive technology manager at the Perkins School for the Blind tries a LightSound device for the first time at the school's library in Watertown, Mass., on March 2, 2024. As eclipse watchers look to the skies in April 2024, new technology will allow people who are blind or visually impaired to hear and feel the celestial event.
Mapping the best route for a spacecraft traveling beyond the Sun's sphere of influence

The heliosphere—made of solar wind, solar transients, and the interplanetary magnetic field—acts as our solar system's personal shield, protecting the planets from galactic cosmic rays. These extremely energetic particles accelerated outwards from events like supernovas and would cause a huge amount of damage if the heliosphere did not mostly absorb them.

Currently, the scientific community cannot reach a consensus on the boundaries or contours of this protected space, and they're exploring mission concepts for an interstellar probe that travels beyond the sun's sphere of influence to answer these questions.

The United Launch Alliance (ULA) has announced a postponement in the final mission of the Delta IV Heavy rocket, now rescheduled for Friday afternoon. This delay comes as the rocket was prepared for its last journey from Cape Canaveral Space Force Base's Space Launch Complex-37. NROL-70 is conducted for the National Reconnaissance Office, carrying a classified payload, speculated to be an Electronic Signals Intelligence Satellite.
