스페이스 클럽 팔콘 9의 SSO-A 사명 발사 일정

[한국항공우주연구원]

Falcon 9 로켓의 주요 이벤트를 따라 Spaceflight의 SSO-A : SmallSat Express Rideshare mission에서 64 명의 작은 궤도를 따라 가십시오.

캘리포니아 주 밴 덴버 (Vandenberg) 공군 기지의 우주 발사 단지 4 - 동쪽에서 오전 9시 31 분 (태평양 표준시 기준 1:31 pm, 1831 GMT) 오전 10시 31 분에 높이 229 피트 (70 미터) 로켓을 내릴 예정이다.

T-0:00:00: Liftoff

After the rocket’s nine Merlin 1D engines pass an automated health check, the Falcon 9 is released from Space Launch Complex 4-East at Vandenberg Air Force Base, California.

T+0:0:59: Max-Q

The Falcon 9 rocket reaches Max Q, the point of maximum aerodynamic pressure. The first stage’s nine Merlin 1D engines produce about 1.7 million pounds of thrust.

T+0:02:21: MECO

The Falcon 9’s nine Merlin 1D engines shut down.

T+0:02:24: Stage 1 Separation

The Falcon 9’s first stage separates from the second stage moments after MECO.

T+0:02:32: Stage 2 Ignition

The second stage Merlin 1D vacuum engine ignites for an approximately 6-minute burn to inject the SSO-A satellites into orbit.

T+0:02:38: Stage 1 Boost-back Burn

A subset of the Falcon 9’s engines ignited to help the rocket reverse course and target a landing on SpaceX’s drone ship “Just Read the Instructions” offshore Vandenberg Air Force Base.

T+0:02:43: Fairing Jettison

The 5.2-meter (17.1-foot) diameter payload fairing jettisons once the Falcon 9 rocket ascends through the dense lower atmosphere. The 43-foot-tall fairing is made of two clamshell-like halves composed of carbon fiber with an aluminum honeycomb core. The fairing halves will deploy parafoils for a controlled descent into the Pacific Ocean.

T+0:05:58: Stage 1 Entry Burn

A subset of the first stage’s Merlin 1D engines ignite for an entry burn to slow down for landing. A final landing burn will occur just before touchdown.

T+0:07:45: Stage 1 Landing

The Falcon 9 rocket’s first stage booster touches down on SpaceX’s drone ship in the Pacific Ocean.

T+0:10:01: SECO 1

The Merlin 1D vacuum engine turns off after placing the SSO-A satellites in an orbit approximately 357 miles (575 kilometers) above Earth.

T+0:13:47: Begin SSO-A Deployment Sequence

The separation sequence begins with deployment of the SSO-A Upper Free Flyer from the Falcon 9 rocket at T+plus 13 minutes, 17 seconds. Four microsatellites will subsequently separate from adapter rings on the Falcon 9 rocket’s second stage, followed finally by release of the Lower Free Flyer around 43 minutes after liftoff. The two free flyers will then continue their mission, deploying an additional 60 smallsats over the following four hours. Final separation of an SSO-A payload is set for around 4 hours, 45 minutes, after liftoff. Credit: Spaceflight
