NASA discovers the cause of a malfunction in the chute during the landing of the asteroid sample

Inconsistent nomenclature in OSIRIS-REx landing plans is what caused the parachute to deploy out of order during the return capsule’s descent to Earth on September 24, NASA says. advertiser In a statement yesterday.

The OSIRIS-REx spacecraft carried samples from the asteroid Bennu to Earth in late September, an “astrobiologist’s dream.” Gizmodo previously reported. Bennu is a remnant of the formation of the solar system, so scrutinizing its composition will provide hints about the primordial components of life, as well as the components of our early solar system. The sample box from the asteroid contains a A larger amount of asteroid fragments than expectedIt is a blessing for scholars. However, these additional materials were discovered outside the can; secovery teams are having difficulties opening the boxwhich contains the bulk of the samples.

The sample was parachuted back to Earth — specifically in the Utah desert — on September 24, and since then NASA has been carefully working to open the case.

The return capsule landed safely on Earth despite the design flaw, but the space agency (naturally) wanted to get to the bottom of the hiccup to ensure it wouldn’t happen again. A video review of the descent and scrutiny of the system design plans indicated that the affected parachute was knocked out of order by the capsules’ parachute actuator wires.

The drug was supposed to spread, slowing the capsule’s descent to the surface when it reached an altitude of about 10,000 feet (3 kilometers). Instead, when the capsule was at an altitude of 100,000 feet (30 km), the anesthetic retaining cord was cut, separating it from the capsule while still in its packaging. Then, when the capsule reached about 9,000 feet (2.7 km), the anesthetic was deployed, completely separating it from the rest of the system. According to a NASA statement, the capsule safely reached Earth thanks to the power of the main parachute.

NASA found the problem in the design plans for OSIRIS-REx, specifically in the liberal use of the word “primary.” In designs of the device that transmits electrical signals, the “main” refers to the main chute, but on the receiver side of the design, the “main” refers to the pyrotechnic device that deploys the anesthetic chute. “Engineers connected the two mains, causing a malfunction in the parachute deployment procedures,” NASA said in a statement.

The agency’s conclusions about the parachute tornado can be confirmed by testing the system that releases the parachutes, located in one of the glove boxes housing the Bennu sample at the Johnson Space Center in Houston. The sample materials will need to be processed first – an exhaustive, if slow, task – but then engineers can delve deeper into the devices, to ensure such a mistake doesn’t happen again.
