NASA’s Europa Clipper on track for Oct. 10 launch to Jupiter’s icy moon despite radiation worries

NeRD

Three weeks from now, NASA’s Europa Clipper probe will lift off and embark on a long-awaited mission to study Jupiter’s icy moon Europa, which scientists think is one of the most promising places to look for life beyond Earth. The launch appears to still be on track for Oct. 10, as per the agency’s original schedule, which comes as a relief to scientists after the team discovered a few possibly defective transistors just months prior that threatened to imperil the mission. Any signs of life on Europa would likely be…

Rocket Lab aborts launch of 5 ‘Internet of Things’ satellites at last second (video)

NeRD

Rocket Lab aborted a launch at the last second today (Sept. 18). The company’s Electron rocket was scheduled to launch five “Internet of Things” satellites for the French company Kinéis today at 7 p.m. EDT (2300 GMT) from New Zealand. The countdown clock reached zero, and Electron appeared to fire up its first-stage engines. But they immediately shut down, resulting in an abort.

NASA’s ‘Hidden Figures’ women awarded Congressional Gold Medals

NeRD

Although they may never completely shed the label, the women who worked for NASA as human computers during the space race are no longer “hidden figures,” and they now have a medal to prove it. On Wednesday (Sept. 18), the women as a group and four individuals who have come to represent their collective experiences were awarded the Congressional Gold Medal, one of the highest civilian honors in the United States. As authorized by Congress, the medals were bestowed to Christine Darden and posthumously to Katherine Johnson, Mary Jackson and…

SpaceX launches 2 European navigation satellites, lands rocket (video)

NeRD

A SpaceX Falcon 9 rocket launched two European navigation satellites tonight (Sept. 17) and then landed safely, acing its 22nd mission. The Falcon 9 rocket, carrying two spacecraft for Europe’s Galileo satnav constellation, lifted off from Cape Canaveral Space Force Station in Florida tonight at 6:50 p.m. EDT (1850 GMT).  The Falcon 9’s first stage returned to Earth safely as planned, landing at sea on the SpaceX droneship “Just Read the Instructions” about 8.5 minutes after launch. According to a SpaceX mission description, it was the 22nd liftoff and landing for this…

FAA plans to fine SpaceX $630,000 for alleged launch violations

NeRD

The U.S. Federal Aviation Administration (FAA) plans to fine SpaceX more than $630,000 for allegedly failing to comply with regulations on two launches last year. “Safety drives everything we do at the FAA, including a legal responsibility for the safety oversight of companies with commercial space transportation licenses,” FAA Chief Counsel Marc Nichols said in an emailed statement today (Sept. 17).  “Failure of a company to comply with the safety requirements will result in consequences,” he added. The first launch cited by the FAA is PSN SATRIA, which lofted an…

NASA astronaut photographs SpaceX’s private Polaris Dawn capsule reentry from ISS (photo)

NeRD

An epic picture of Polaris Dawn’s nighttime reentry has been beamed to Earth from space. NASA astronaut Don Pettit caught the conclusion of Polaris Dawn, a private space mission that included the first-ever commercial spacewalk, during its SpaceX Dragon spacecraft’s return to Earth before dawn on Sunday (Sept. 15). “In addition to the multi-colored entry trail over Florida, the basic cone shape of the Dragon capsule can be seen,” Pettit wrote on X, formerly Twitter, Sunday afternoon about his picture taken from the International Space Station (ISS).

SpaceX’s private Polaris Dawn astronauts splash down to end historic spacewalk mission (video)

NeRD

Polaris Dawn has landed. The historic SpaceX astronaut mission — which conducted the first-ever private spacewalk, among other achievements —returned to Earth today (Sept. 15), splashing down safely in the Gulf of Mexico off the coast of Florida at 3:36 a.m. EDT (0736 GMT). “Polaris Dawn we are mission complete. Thanks for all the big help pulling this mission together,” said mission commander Jared Isaacman after the crew splashed down in the ocean.

Astronauts 3D-print first metal part while on ISS

NeRD

ESA scientists have successfully demonstrated 3D printing of a metal part in space for the first time.  3D printing in space poses challenges, as many methods rely on gravity to position materials during the printing process. This is because when creating metal structures, molten metal is often used as part of the filament, or printable medium. In space, its behavior can be unpredictable, which can result in poor-quality objects, as the filament might shift or be placed incorrectly due to the lack of gravitational forces. Scientists therefore had to adapt…
