With weather at 80 percent go for launch and everything proceeding as planned, optimism and enthusiasm were high at Monday morning’s Ascent Abort-2 flight test preview news conference at Kennedy Space Center in Florida.

“We are incredibly excited,” said Jenny Devolites, Ascent Abort-2 crew module manager and test conductor. “It’s such an honor to be a part of this activity and to have this opportunity.”

The Ascent Abort-2 flight test of the launch abort system for NASA’s Orion spacecraft, featuring a test version of the crew module, will lift off from Space Launch Complex 46 at Cape Canaveral Air Force Station Tuesday, July 2. The four-hour launch window opens at 7 a.m. EDT. NASA TV will broadcast launch activities, starting at 6:40 a.m. A postlaunch briefing is  scheduled for approximately two hours after launch. Audio of this briefing will stream live on the agency’s website.

Orion will help pave the way for Artemis missions with astronauts to the Moon and then Mars.

“This test is extremely important,” said Mark Kirasich, Orion program manager. “Our Launch Abort System is a key safety feature of the spacecraft — it will protect the crew members who fly onboard Orion during the most challenging part of the mission, which is the ascent phase.”

Ascent Abort-2 will verify Orion’s abort system can pull the crew module away from an emergency during its ascent to space. The two main objectives: execute the abort by demonstrating it can be completed end to end, and collect key data. There are approximately 900 sensors — including temperature sensors, pressure sensors and microphones —located throughout the vehicle.

At liftoff, the booster will provide about 500,000 pounds of thrust. It will take 55 seconds to ascend to 31,000 feet, traveling more than 800 mph, at which point the abort will be initiated and the abort motor will ignite. Also igniting will be the attitude control motor, which provides steering.

Twenty-seven seconds after the abort, the jettison motor will ignite, pulling away the Launch Abort System from the crew module. The crew module will then free-fall and descend back to the ocean. As a backup communication system, 12 ejectable data recorders eject into the water in pairs. The highest altitude reached will be about 45,000 feet.

“It’s certainly a very exciting test for us tomorrow because it is so important,” NASA astronaut Randy Bresnik said. “The neat part is the next time this whole Launch Abort System flies, there will be crew underneath it in Artemis 2.”

Preview News Conference for Ascent Abort-2 Flight Test Today at 11:30 a.m. EDT

AA-2 mission patchNASA will host a preview news conference for the Ascent Abort-2 flight test of the launch abort system for NASA’s Orion spacecraft at 11:30 a.m. Monday, July 1, at NASA’s Kennedy Space Center in Florida. The flight test will help pave the way for Artemis missions with astronauts to the Moon and then Mars.

The launch and preview news conference will air on NASA TV and the agency’s website. Participants include:

  • Mark Kirasich, Orion program manager
  • Jenny Devolites, Ascent Abort-2 test conductor
  • Randy Bresnik, NASA astronaut

The blog will feature highlights from the preview news conference.

The AA-2 flight test’s four-hour launch window opens at 7 a.m. EDT Tuesday, July 2. A test version of the crew module will launch from Space Launch Complex 46 at Cape Canaveral Air Force Station in Florida. NASA TV coverage will begin at 6:40 a.m.

Managers Give “Go” to Proceed to Launch at Readiness Review

A test version of NASA’s Orion crew module is ready for rollback at Launch Complex 46 at Cape Canaveral Air Force Station in Florida. During a Launch Readiness Review on June 28, the team preparing to launch Orion’s Ascent Abort-2 flight test gave a “go” to proceed to launch on Tuesday, July 2.

At an Orion Program Launch Readiness Review held June 28, the team preparing to launch Orion’s Ascent Abort-2 flight test gave a “go” to proceed to launch on Tuesday, July 2. Pending the outcome of a range readiness review to be held Monday, NASA is targeting the opening of a four-hour launch window at 7 a.m. EDT. Engineers will close out final operations at the launch pad over the weekend and on Monday to prepare for the test.

The Mobile Access Structure at Space Launch Complex 46 will be pulled back for the final time Tuesday morning before launch. Technicians had rolled it back earlier this week to perform end-to-end systems checkouts. The team also will temporarily pull it back on Monday to remove tape protecting sensors that will be used to collect data during the test.

NASA will hold an overview on the test at 11:30 a.m. Monday, which will air on NASA TV and the agency’s website.

Dragon Cargo Spacecraft Berthed to Station

Two days after its launch from Cape Canaveral Air Force Station in Florida, the SpaceX Dragon cargo spacecraft was installed on the Earth-facing side of the International Space Station’s Harmony module on Monday, May 6, at 9:32 a.m. EDT.

The 17th contracted commercial resupply mission from SpaceX (CRS-17) delivered more than 5,500 pounds of research, crew supplies and hardware to the orbiting laboratory. After Dragon spends approximately one month attached to the space station, the spacecraft will return to Earth with about 4,200 pounds of cargo and research.

Dragon Spacecraft Captured at 7:01 a.m. EDT

While the International Space Station was traveling over the north Atlantic Ocean, astronauts David Saint-Jacques of the Canadian Space Agency and Nick Hague of NASA grappled Dragon at 7:01 a.m. EDT using the space station’s robotic arm Canadarm2.

Ground controllers will now send commands to begin the robotic installation of the spacecraft on bottom of the station’s Harmony module. NASA Television coverage of installation is scheduled to begin at 9 a.m. Watch online at www.nasa.gov/live.

The Dragon lifted off on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida Saturday, May 4 with more than 5,500 pounds of research, equipment, cargo and supplies that will support dozens of investigations aboard the orbiting laboratory.

Here’s some of the research arriving at station:

NASA’s Orbiting Carbon Observatory-3 (OCO-3) examines the complex dynamics of Earth’s atmospheric carbon cycle by collecting measurements to track variations in a specific type of atmospheric carbon dioxide. Understanding carbon sources can aid in forecasting increased atmospheric heat retention and reduce its long-term risks.

The Photobioreactor investigation aims to demonstrate how microalgae can be used together with existing life support systems on the space station to improve recycling of resources. The cultivation of microalgae for food, and as part of a life support system to generate oxygen and consume carbon dioxide, could be helpful in future long-duration exploration missions, as it could reduce the amount of consumables required from Earth.

CRS-17 Liftoff No Earlier Than Friday, May 3, at 3:11 EDT

NASA and SpaceX are targeting no earlier than Friday, May 3, for the launch of the company’s 17th commercial resupply mission to the International Space Station. Launch is scheduled for 3:11 a.m. EDT from Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida.

On April 29, the space station team identified an issue with one of the station’s Main Bus Switching Units (MBSU) that distributes power to two of the eight power channels on the station. There are no immediate concerns for the crew or the station.

Flight controllers are scheduled to perform a series of maneuvers to robotically swap the failed MSBU for a spare on Wednesday, May 1 and Thursday, May 2. After the swap is complete, flight controllers will conduct a series of checkouts on the newly installed MBSU and take steps to return the station to full power capability to support SpaceX capture and berthing.
