Sounds like my in-house Rocket Scientist/Super Model is busy this afternoon, so I’ll put up the space updates.

First, the mysterious X-37B is also taking along a not so hush-hush experiment. The METIS is similar to other tests such as LDF and MISSE on the reaction of various materials exposed to space for varying durations.

Building on more than a decade of data from International Space Station (ISS) research, NASA is expanding its materials science research by flying an experiment on the U.S. Air Force X-37B space plane.

By flying the Materials Exposure and Technology Innovation in Space (METIS) investigation on the X-37B, materials scientists have the opportunity to expose almost 100 different materials samples to the space environment for more than 200 days. METIS is building on data acquired during the Materials on International Space Station Experiment (MISSE), which flew more than 4,000 samples in space from 2001 to 2013.

“By exposing materials to space and returning the samples to Earth, we gain valuable data about how the materials hold up in the environment in which they will have to operate,” said Miria Finckenor, the co-investigator on the MISSE experiment and principal investigator for METIS at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “Spacecraft designers can use this information to choose the best material for specific applications, such as thermal protection or antennas or any other space hardware.”

We’re curious about something not mentioned in the release. How different is the orbit of the X-37B from the ISS, in terms of both altitude and inclination, and what effects might that have on the exposed materials?

Next up, Space-X. We’ve all enjoyed watching Elon Musk’s Falcon 9 attempt to safely land after orbital launch missions. Looks like they’ll try again in June. But the other major endeavor underway at Space-X is to crew certify a manned spacecraft. And one of the key tests for that is the pad abort. We’ve all seen the escape tower atop Mercury and Apollo capsules. Space-X uses a rather different approach with their manned variant of the Dragon spacecraft.


That’s an unmanned test, but I’m thinking Space-X could make some money selling that as a carnival ride.
