Getting to Upmass: A Dragon’s Tale

A Station that Needs Everything
A Scrappy Startup Contracted to Ship 35.4 Metric Tons of It
Ought to be Easy Enough, Right?

The International Space Station (ISS) is not exactly a self-sufficient outpost. The station’s occupants can’t jump into a Soyuz and pop over to an orbiting Wal-Mart when they run out of food, water or toothpaste. Everything the six astronauts need to survive — save for the random plastic wrench or replacement part they can now 3-D print — must be shipped up from the majestic blue planet 400 km below them.

The second day of the Next-Generation Suborbital Researchers Conference took place in Colorado on Friday. Although I wasn’t able to attend, I have compiled highlights via Twitter posts. (You can follow along with hashtag #nsrc2016.)

Below is a summary of updates that cover Sierra Nevada Corporation, Cecil Airport, Spaceport Colorado, FAA Office of Commercial Space Transportation, World View Enterprises, NASA Flight Opportunities Program.

There was a presentation by Charles Walker, who was the first person to perform commercial experiments in space as a payload specialist on three space shuttle missions.

A separate panel discussion on human-tended space research reached the unsurprising consensus that government should lift its ban on sending scientists into space with their experiments.

SpaceX’s cancellation of a Falcon 9 launch on Thursday was the second scrub in 24 hours related to fueling problems.

The launch was canceled with 1 minute, 40 seconds left to go in the countdown. The problem related to loading of super cold “densified” liquid oxygen (LOX) that has been added to the newest variant of SpaceX’s launch vehicle.

ESA to Invest in Sierra Nevada’s Dream Chaser

Sierra Nevada Corporation is receiving an investment from ESA for its Dream Chaser spacecraft:

Once the agreement is signed, ESA will begin work building the first flight model of the International Berthing and Docking Mechanism (IBDM), which Sierra Nevada’s Dream Chaser Cargo System will use to attach itself to the space station.

ESA said it would spend 33 million euros ($36 million) to complete the design of the IBDM and build a flight model for Dream Chaser’s first cargo run. Future IBDMs will be financed by Sierra Nevada, ESA said.

ESA and Sierra Nevada in early 2014 agreed to adapt the IBDM to Sierra Nevada’s winged Dream Chaser, which was originally designed to carry astronauts and more recently has been adapted for unmanned cargo missions.

The agency spent about 8 million euros on the early work, which slowed after Sierra Nevada failed to win a NASA contract to send commercial crews to the space station.

ESA said it had spent some 20 million euros in total in recent years working on IBDM and on preparatory work for Dream Chaser.

At a press conference last week, ESA Director-General Johann-Dietrich Woerner said it was possible that Dream Chaser would be launched aboard Europe’s Ariane 5 booster from French Guiana. He said ESA could use the vehicle to launch microgravity experiments into space that would be returned to Earth.

Praise for NASA’s Commercial Cargo Contract Awards

CSF_logo2Commercial Spaceflight Federation

NASA announced three cargo contract awards to ensure robust and affordable transportation of critical supplies, scientific experiments and commercial payloads to and from the International Space Station (ISS) through at least 2024. NASA selected Orbital ATK, Sierra Nevada Corporation, and SpaceX to continue and expand upon its successful public-private partnerships with American companies to obtain reliable cargo resupply services for the ISS.
