NASA and commercial industry partners Boeing and SpaceX are making significant advances in preparing to launch astronauts from U.S. soil for the first time since the space shuttle’s retirement in 2011. As part of the Commercial Crew Program’s public-private partnership, both companies are fine-tuning their designs, integrating hardware, and testing their crew spacecraft and rockets to prepare for test flights

Here’s a look at the milestones so far in 2018:

Crew and International Space Station

In March, astronaut Eric Boe visited Space Launch Complex 41 (SLC-41) at Cape Canaveral Air Force Station in Florida. He had the opportunity to see a United Launch Alliance (ULA) Atlas V rocket on the pad and check out the Crew Access Tower. The crew assigned to Boeing’s Starliner spacecraft will launch from SLC-41 atop an Atlas V on their way to the International Space Station.

Also in March, astronauts Bob Behnken, Eric Boe, Doug Hurley and Suni Williams toured SpaceX’s Launch Complex 39A facilities to survey the launch pad and tower modifications. The crew assigned to fly on the company’s Crew Dragon will liftoff aboard a SpaceX Falcon 9 rocket from historic pad 39A.

Later in April, NASA trained Boeing and SpaceX teams to operate the Mine Resistant Ambush Protected (MRAP) armored vehicle designed to help personnel escape the launch pad in the unlikely event of an emergency on launch day. Astronauts and ground crews would have the option to shelter in place in the MRAP, or drive away from the launch pad.

In June, astronauts Ricky Arnold and Drew Feustel installed new cameras on the space station during a spacewalk. These high-definition cameras will provide NASA with an enhanced look of Boeing and SpaceX’s capsules as they approach and dock to the station.

Boeing continues to manufacture its Starliner spacecraft inside NASA Kennedy Space Center’s Commercial Crew and Cargo Processing Facility in Florida. The company is currently producing three Starliner spacecraft. Boeing’s Starliner is designed to be reused up to 10 times.

In January, astronauts had the opportunity to train using mixed reality—a combination of real world and virtual environment—technology to practice exiting their seats in an uncommon landing situation. The crew were suited up and secured in a mock-up Starliner allowing them to simulate removing their seat harness and opening the hatch of the spacecraft without assistance.

In February, Boeing completed the first in a series of reliability tests of the Starliner flight drogue and main parachute systems in Yuma, Arizona. Data collected from these tests continue to improve accuracy of computer models in predicting parachute performance and verifying reliability.

In March, teams from Boeing, NASA and ULA gathered in control rooms across the country for an integrated crew exercise of Boeing’s Orbital Flight Test. Boeing also completed two joint rendezvous docking system simulations with the space station.

In May, the White Room, which astronauts will walk through just before boarding Starliner, was installed on SLC-41.

In June, Boeing, NASA and U.S. Army teams rehearsed safely bringing the Starliner spacecraft home to Earth at White Sands Missile Range in New Mexico. When the vehicle prepares for landing, it will deploy a parachute system and touch down in the desert. This exercise tested procedures and communication in place for recovery teams to retrieve the capsule and the crew after landing.

Also in June, Boeing, ULA and NASA simulated an evacuation from SLC-41 to practice escaping from the pad in the unlikely event of an emergency on launch day. Astronauts and ground crews rehearsed zip lining from the launch tower to the ground and driving an MRAP to a triage site for medical attention. Boeing also connected the upper and lower domes of its Crew Flight Test spacecraft and attached its docking system in June.

In July, the dual engine Centaur for the ULA Atlas V rocket that will launch Starliner in the uncrewed Orbital Flight Test was completed.

SpaceX

SpaceX continues to test its systems and integrate its launch infrastructure to support the Crew Dragon capsule. The company currently has six Crew Dragon modules in various stages of production and testing.

In March, SpaceX performed two parachute tests, the company’s 14th and 15th overall parachute test supporting Crew Dragon development in the Mojave Desert in Southern California. The latter test demonstrated Crew Dragon’s ability to land safely in an off-nominal situation, deploying only one of the system’s two drogue parachutes and three of the four main parachutes.

In April, astronauts completed a SpaceX spacesuit fit check at the company’s headquarters in Hawthorne, California. These suits will help keep the astronauts safe and comfortable throughout their journey to and from the space station. The company is manufacturing custom suits for each astronaut to ensure a proper fit and comfortable ride on Crew Dragon.

Also in April, SpaceX, NASA and the Department of Defense (DOD), conducted joint rescue and recovery exercises in the Atlantic Ocean off of Florida’s eastern coast. In this simulation, DOD pararescue specialists jumped from military aircraft, parachuted to the water, and simulated stabilizing the Crew Dragon capsule and safely removing astronauts from the spacecraft.

In May, SpaceX completed its 16th overall parachute system test for Crew Dragon at Naval Air Facility El Centro in Southern California. This test demonstrated the system’s ability to land the spacecraft safely in the unlikely event of a low altitude abort.

In June, the Crew Dragon capsule for SpaceX’s uncrewed flight test, Demo-1, arrived at Plum Brook Station at NASA’s Glenn Research Center in Ohio. There, the spacecraft underwent testing in the In-Space Propulsion Facility—the world’s only facility capable of testing full-scale upper-stage launch vehicles and rocket engines under simulated high-altitude conditions. The chamber allowed SpaceX and NASA to verify Crew Dragon’s ability to withstand the extreme temperatures and vacuum of space. Crew Dragon also completed acoustical vibration testing on-site at Plum Brook Station.

In July, SpaceX shipped its Crew Dragon spacecraft to Kennedy Space Center in Florida for processing in preparation for Demo-1, and completed its first high-altitude balloon drop test – and 17th overall parachute system test – in the Mojave Desert from ~50,000 feet.  SpaceX also completed another major round of astronaut and operations team training and simulations in preparation for the Demo-2 mission. Heat shield qualification, as well as a majority of qualification testing for both Crew Dragon and Falcon 9, is now complete.
