Of Course I Still Love You has arrived at the landing zone for the STP-2 mission! A record-breaking 1236 km downrange, that took almost 6 days to reach.




23 июн.

The fairing recovery unit, comprising GO Ms. Tree and GO Navigator, has just arrived at the center core landing zone where OCISLY is waiting. They will soon head even further downrange to the fairing landing zone. This could be up to 1400 km from the launchpad.

GO MS. Tree (Mr. Steven) has arrived at the fairing recovery zone! It's an impressive 1350 km downrange. (Droneship is stationed 1236 km downrange.)

Landing Zone Weather Update: Considering their significant offshore position, weather is looking good! Max waves of 1.3m and max wind gusts of 20 km/h at surface level. Predictions via http://ventusky.com

The @AF_SMC @SpaceX STP-2 mission will deploy sats to 3 different orbits. Orbit 1 is 300 x 860 km x 28.5 deg, for Oculus-ASR, Armadillo, TBEx 1/2, Stnagsat, LEO. I'm not sure if NPSAT-1, PSAT-2, BRICSAT-P, TEPCE 1/2 are also going to Orbit 1 - can anyone confirm? (1/3)

Orbit 2 is 720 x 720 km x 24.0 deg, for COSMIC-2 FM1 to FM6, GPIM, OTB, Prox-1, Lightsail-2, and FalconSat-7.

Orbit 3 is 6000 x 12000 km x 45.0 deg, for the DSX research satellite.

The Falcon 9 second staget will perform a passivation burn and end up in an orbit slightly different from DSX.

Falcon Heavy still looking beautiful as it targets 2:30am for STP-2's launch.

ЦитироватьPhotos: Falcon Heavy reaches pad 39A for its first night launch
June 24, 2019Stephen Clark

SpaceX's Falcon Heavy rocket rolled out of its hangar and up the ramp to pad 39A at NASA's Kennedy Space Center in Florida, then was raised vertical at the seaside launch complex early Monday in preparation for a late-night liftoff with two dozen weather observation and technology demonstration satellites.

The rocket stands 229 feet (70 meters) tall and 40 feet (12.2 meters) wide, made up of three Falcon 9 rocket boosters bolted together to produce more than 5 million pounds of the ground-shaking thrust at liftoff.

The Falcon Heavy is set for launch during a four-hour window opening at 11:30 p.m. EDT Monday (0330 GMT Tuesday) on the Space Test Program-2 mission sponsored by the U.S. Air Force. It will be the third flight of the Falcon Heavy — the world's most powerful launcher — the first Falcon Heavy launch at night.
See our Mission Status Center for live coverage of the countdown and launch.

T-minus 1 hour, 38 minutes. A weather briefing to the SpaceX launch team a short while ago showed that all weather criteria at the Kennedy Space Center are currently observed "go" for launch.

There is now a 90 percent chance of acceptable weather for liftoff of the Falcon Heavy at 2:30 a.m. EDT (0630 GMT).

At launch time, forecasters expect only a few clouds, southwest winds of 8 to 12 mph, and a temperature of 82 degrees Fahrenheit.

The SpaceX launch team has given the "go" for propellant loading and launch.

RP-1 kerosene should now be loading into the Falcon Heavy rocket.

Liquid oxygen should be flowing into the rocket at this time. Venting visible at launch pad 39A suggests propellant loading is proceeding ahead of the Falcon Heavy's third launch at 2:30 a.m. EDT (0630 GMT).

Falcon Heavy vertical at the pad on this perfectly clear night. It's going to light up the sky soon. @Teslarati view from 525ft, VAB roof.

We have posted a launch timeline with illustrations of the major events during this morning's mission, which will last more than three-and-a-half hours from liftoff through deployment of the last of the 24 spacecraft on-board the rocket.

Assuming the Falcon Heavy takes off at 2:30 a.m. EDT (0630 GMT), the last of the payloads -- the Air Force's experimental DSX payload -- will deploy from the rocket at 6:04 a.m. EDT (1004 GMT).

An interesting payload is GPIM, the NASA/USAF/Ball Aerospace Green Propellant Infusion Mission, testing hydroxyl ammonium nitrate (NH3OHNO3, or HAN) as a less toxic alternative to hydrazine

GPS-RO meteorology is quite common now, so it's not clear to me if the long-planned COSMIC-2 is still super relevant.


4 мин. назад

Another major space weather payload aboard is the US-Taiwanese COSMIC-2/FORMOSAT-7 project, with six 278 kg satellites to study the atmosphere using GPS occultation.


7 мин. назад

The biggest payload on STP-2 is AFRL's DSX, the 670 kg Demonstration and Science Experiments satellite with space weather experiments. Based on the 2.6-metre-diameter ESPA ring, the satellite will deploy electric-field-measuring wire antennae spanning 54 metres.

All weather criteria are currently observed "go" for launch at this time.
