Engineers Solve Data Glitch on NASA’s Voyager 1

A critical system aboard the probe was sending garbled data about its status. Engineers have fixed the issue but are still seeking the root cause.

Engineers have repaired an issue affecting data from NASA’s Voyager 1 spacecraft. Earlier this year, the probe’s attitude articulation and control system (AACS), which keeps Voyager 1’s antenna pointed at Earth, began sending garbled information about its health and activities to mission controllers, despite operating normally. The rest of the probe also appeared healthy as it continued to gather and return science data.

The team has since located the source of the garbled information: The AACS had started sending the telemetry data through an onboard computer known to have stopped working years ago, and the computer corrupted the information.

Suzanne Dodd, Voyager’s project manager, said that when they suspected this was the issue, they opted to try a low-risk solution: commanding the AACS to resume sending the data to the right computer.

Years after shuttle, NASA rediscovers the perils of liquid hydrogen

$1:

America's space agency on Saturday sought to launch a rocket largely cobbled together from the space shuttle, which itself was designed and built more than four decades ago.

As the space shuttle often was delayed due to technical problems, it therefore comes as scant surprise that the debut launch of NASA's Space Launch System rocket was scrubbed a few hours before its launch window opened. The showstopper was an 8-inch diameter line carrying liquid hydrogen into the rocket. It sprang a persistent leak at the inlet, known as a quick-disconnect, leading onboard the vehicle.

Valiantly, the launch team at Kennedy Space Center tried three different times to stanch the leak, all to no avail. Finally at 11:17 am ET, hours behind on their timeline to fuel the rocket, launch director Charlie Blackwell-Thompson called a halt.

And that's why SpaceX uses Kerosene and Liquid Oxygen, or Methanol and Liquid Oxygen in their rockets.

I am obviously way behind the times because I didn't know Neptune had rings.
