Welcome to Edition 6.40 of the Rocket Report! There was a lot of exciting news this week. For the first time, SpaceX launched a reusable Falcon 9 booster for a 20th flight. A few miles away at Cape Canaveral, Boeing and United Launch Alliance completed one of the final steps before the first crew launch of the Starliner spacecraft. But I think one of the most interesting things that happened was NASA’s decision to ask the space industry for more innovative ideas on how to do Mars Sample Return. I have no doubt that space companies will come up with some fascinating concepts, and I can’t wait to hear about them.

Going vertical Down Under. Gilmour Space has raised its privately-developed Eris rocket vertical on a launch pad in North Queensland for the first time, the Australian Broadcasting Corporation reports. This milestone marks the start of the next phase of launch preparations for Eris, a three-stage rocket powered by hybrid engines. If successful, Eris would become the first Australian-built rocket to reach orbit. Gilmour says the maiden flight of Eris is scheduled for no earlier than May 4, pending launch permit approvals. This presumably refers to a commercial launch license from the Australian government.
