NASA is providing live coverage of the return to Earth of SpaceX’s Crew Dragon after five days docked to the International Space Station.

Known as Demo-1, SpaceX’s inaugural mission with NASA’s Commercial Crew Program is an important uncrewed end-to-end flight test of the new system’s capabilities.

The spacecraft departed the space station at 2:32 a.m. EST and is on track for a splashdown in the Atlantic Ocean about 200 nautical miles off the eastern shore of Florida.

At approximately 7:48 a.m., Crew Dragon will separate from its trunk containing its solar array and radiator. Four minutes later, the spacecraft’s thrusters will initiate the deorbit burn at 7:52 a.m. The 15-minute, 25-second burn will place the Crew Dragon on its final re-entry path into Earth’s atmosphere. The nosecone will be closed before the spacecraft enters the atmosphere.

At about 8:41 a.m., drogue parachutes will deploy, and the four main chutes will begin to open less than a minute later to slow the Crew Dragon during its final descent prior to its water landing at about 8:45 a.m.

SpaceX’s two recovery ships are positioned nearby to recover Crew Dragon and return it to Cape Canaveral Air Force Station, Florida, to conclude its mission.

Medad Rufus reports two balloons with 434 MHz transmitters built by Imperial College Students for the Exploration and Development of Space (ICSEDS) will launch from Wormwood Scrubs, London on Saturday, March 9.

On the UK High Altitude Society reflector Medad posted:

This is a launch announcement for the launch of ICSPACE6 & 7 from Wormwood Scrubs, London, UK. We have had some success with the launches of our previous pico balloons and we hope it works 100% this time.

The hardware is nearly identical to the previous launch; only software changes made. The winds are expected to take it towards the Netherlands/Belgium and further east into Germany.

Here is the information about the balloons to be launched tomorrow:

Callsign: ICSPACE6
RTTY: 434.600 MHz USB
50 baud 745 Hz shift ASCII-8 no parity 2 stop bits
Launch time aim: 10:40 am on March 9
Transmits 10 pips before transmitting message. 30s gap between each transmission

Callsign: ICSPACE7
RTTY: 434.250 MHz USB
50 baud 745 Hz shift ASCII-8 no parity 2 stop bits
Launch time aim: 11:40 am on March 9
Transmits 10 pips before transmitting message. 30s gap between each transmission when below 3000m. Above 3000m, it will transmit with a gap of 60 seconds.

We appreciate all listeners for our flights. I hope this flight goes well.

Here is information about the launch of ICSPACE4 & 5 four weeks ago.

At 2:32 a.m. EST, Crew Dragon undocked from the International Space Station to begin the final phase of its uncrewed Demo-1 flight test. The spacecraft is slowly maneuvering away from the orbital laboratory into an orbital track that will return it and its cargo safely to Earth.

NASA will continue to provide live coverage until Crew Dragon is out of the immediate area of the station and will resume at 7:30 a.m. for the reentry, splashdown, and recovery.

In about five hours, the Crew Dragon will separate from its trunk whose exterior contains a solar array that provided power to Dragon and a radiator to reject heat.

Following separation, Crew Dragon’s thrusters will initiate the spacecraft’s deorbit burn at about 7:52 a.m. The 15-minute, 25-second burn will place the Crew Dragon on its final re-entry path into Earth’s atmosphere. The spacecraft is expected to splashdown in the Atlantic Ocean at about 8:45 a.m., its speed slowed by an enhanced parachute system in which drogue parachutes will deploy about four minutes before landing to unfurl four main chutes less than a minute later.

After Crew Dragon lands in the Atlantic Ocean, SpaceX’s recovery ship will recover it and return it to Port Canaveral, Florida to conclude its mission.

SpaceX’s inaugural mission with NASA’s Commercial Crew Program is an important end-to-end to test of the new system’s capabilities.
