Blue Origin delays New Glenn’s return to flight until January

Blue Origin now aims to fly New Glenn again in January, missing its 2026 goal after May's launch pad explosion, a delay that also hits Amazon Leo and NASA.

What is a light-day? The milestone Voyager 1 is closing in on

The milestone Voyager 1 is closing in on — one light-day away from Earth — is about distance, not time. And it's very, very far.

Voyager 1 Briefly Goes Silent, Scaring Everyone

Voyager 1 went silent for more than 24 hours on October 18 and 19, and the team is still trying to figure out what happened. Diagnostic data collected after communications were restored showed a group of thrusters went offline, with backup units kicking in. This indicates the onboard computer detected some kind of anomaly, and whether it is a recurrence of previously observed clogged fuel lines will have to be investigated. It is currently unknown whether the blackout is related to a recent switch of multiple instruments to lower-power versions, which should give both spacecraft a few more years before power reserves fall below usable levels.

Roman Telescope Saves Fuel, Doubles Mission

NASA's Nancy Grace Roman Space Telescope, launched August 30 on a Falcon Heavy, now has enough fuel for at least 22 years of science operations, more than double its original 10-year design life. The gain comes from three factors contributing roughly four years each: the spacecraft came in 18% under its mass budget (8,056 kg vs a planned 9,800 kg ceiling), its first mid-course correction burn used just 18 kg of a budgeted 200 kg, and the upcoming orbit insertion burn is expected to come in under budget too. The story draws a parallel to James Webb Space Telescope, which similarly got about 20 years of fuel (double its estimate) from precise injection and efficient burns back in 2022.

Artemis II Rocket Was Powerful Enough To Disrupt GPS

A pre-print study found that Artemis II's rocket stages had a surprisingly wide impact on the upper atmosphere. The first stage occurred too low to significantly affect the ionosphere. But the 2nd and 3rd stage burns were large enough that they could have sustainably disrupted GPS signals at the time. Waves also traveled through the atmosphere across the entirety of North America in the form of gravity waves. The research relied on thousands of sensors across the globe.
