Thermal imaging on the quality control line

On a high-speed food and beverage line, what you can see is not always what is happening. Thermal imaging adds a different layer of control. Instead of relying on surface appearance, it measures heat distribution as seals are formed and products move through the line, providing continuous, 100% in-line inspection instead of just sampling.

Glitch with 1980s computer stops work on NASA's Hubble Space Telescope

The Hubble Space Telescope was deployed April 25, 1990, from the space shuttle Discovery. Avoiding distortions of the atmosphere, Hubble has an unobstructed view peering to planets, stars, and galaxies, with some calculated to be more than 13.4 billion light years away.

The 1980s are back at NASA, and it's not a great look.

Engineers at the Goddard Space Flight Center are working to resolve an issue with the payload computer on the Hubble Space Telescope. The computer halted on Sunday, June 13, shortly after 4 p.m. EDT. After analyzing the data, the Hubble operations team is investigating whether a degrading memory module led to the computer halt.

The team is preparing to switch to one of several back-up modules. The computer will then be allowed to run for a defined duration to verify that the problem has been solved. The team would then restart all science instruments and return the telescope to normal science operations.

The purpose of the payload computer is to control and coordinate the science instruments onboard the spacecraft. After the halt occurred on Sunday, the main computer stopped receiving a "keep-alive" signal, which is a standard handshake between the payload and main spacecraft computers to indicate all is well. The main computer then automatically placed all science instruments in a safe-mode configuration. Control center personnel at NASA's Goddard Space Flight Center in Greenbelt, MD, restarted the payload computer on Monday, June 14, but it soon experienced the same problem.

The payload computer is a NASA Standard Spacecraft Computer-1 (NSSC-1) system built in the 1980s that is located on the Science Instrument Command and Data Handling unit. The computer's purpose is to control and coordinate the science instruments and monitor them for health and safety purposes. It is fully redundant in that a second computer, along with its associated hardware, exists on orbit that can be switched over to in the event of a problem. Both computers can access and use any of four independent memory modules, which each contain 64K of Complementary Metal-Oxide Semiconductor (CMOS) memory. The payload computer uses only one memory module operationally at a time, with the other three serving as backups.

The science instruments will remain in a safe-mode state until the issue is resolved. The telescope itself and science instruments remain in good health.

Launched in 1990, Hubble has contributed greatly to our understanding of the universe over the past 30 years.

UPDATE FROM NASA: JUNE 22, 2021
NASA continues to work to resolve a problem with the Hubble Space Telescope payload computer that halted on June 13. After performing tests on several of the computer's memory modules, the results indicate that a different piece of computer hardware may have caused the problem, with the memory errors being only a symptom.

The operations team is investigating whether the Standard Interface (STINT) hardware, which bridges communications between the computer's Central Processing Module (CPM) and other components, or the CPM itself is responsible for the issue. The team is currently designing tests that will be run in the next few days to attempt to further isolate the problem and identify a potential solution.

This step is important for determining what hardware is still working properly for future reference. If the problem with the payload computer can't be fixed, the operations team will be prepared to switch to the STINT and CPM hardware onboard the back-up payload computer. The team has conducted ground tests and operations procedure reviews to verify all the commanding required to perform that switch on the spacecraft.

If the back-up payload computer's CPM and STINT hardware is turned on, several days will be required to assess the computer performance and restore normal science operations. The back-up computer has not been powered on since its installation in 2009; however, it was thoroughly tested on the ground prior to installation on the spacecraft.
