The Apollo 11 mission, which landed the first two humans on the Moon, remains one of mankind’s most impressive achievements. To honor that historic event on its 50th anniversary, several activities are taking place at Kennedy Space Center in Florida, including multiple shows on NASA TV and the agency’s website:
Tuesday, July 16: Astronaut Michael Collins, who served on that historic mission in July 1969, will start the day with a visit to the Astronaut Crew Quarters in Kennedy’s Neil Armstrong Operations & Checkout Building before participating in the day’s televised events.
From 9:15 to 10 a.m. EDT, Collins will speak with Kennedy Director Bob Cabana at Pad 39A, the site of the July 16, 1969, launch. Cabana was the commander of STS-88, the first International Space Station assembly mission, which celebrated its 20th anniversary on Dec. 10, 2018.
Friday, July 19: Tune in to a pair of special live broadcasts from Kennedy’s Apollo/Saturn V Center. The first, an Apollo 11 show titled “NASA’s Giant Leaps: Past and Future,” is from 1 to 3 p.m. EDT. It will honor the heroes of Apollo, and examine NASA’s future plans, including the Artemis missions that are part of the agency’s Moon and Mars human space exploration. That will be followed by a program titled “STEM Forward to the Moon” from 3 to 3:30 p.m. EDT, featuring kids across the nation participating in Moon landing simulations and other activities.
Remember to tune in to NASA TV and the agency’s website for the special Apollo 11 coverage.
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.”
NASA 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.
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.
