UAE mission to space delayed; new launch date, time announced: As it happened

[Editor's Note: This blog is now closed. Tune in for updates on the next launch attempt, scheduled for Thursday, March 2. Read more about it here.]

The UAE is shooting for the stars again — with astronaut Sultan AlNeyadi blasting off for the longest Arab space mission in history.

AlNeyadi, the second Emirati to take the UAE flag to space, is set to become the Arab world's first long-term mission specialist. Together with his crewmates from Nasa and Roscosmos, he will be spending 180 days on board the orbiting laboratory of the International Space Station (ISS), conducting experiments that will significantly contribute to humanity's understanding of life on and beyond Earth.

Khaleej Times has all hands on deck to bring you real-time updates from the ground station at Dubai's Mohammed Bin Rashid Space Centre (MBRSC) and the launch site Kennedy Space Centre at Cape Canaveral in Florida, US.

AlNeyadi was expected to blast off from Earth and embark on a 25-hour journey to the ISS at 10.45am (UAE time).

Here's what happened during the launch attempt on February 27:

10.27am: 25-hour flight to ISS

SpaceX Crew-6 is expected to reach the ISS 25 hours after launch. The microgravity laboratory is orbiting Earth every 90 minutes at a velocity of 28,000kmph and the journey to the space station is a series of rocket burns or engine firings that must be precisely timed to achieve the correct orbit.

SpaceX Crew-1 reached the ISS in 28 hours; SpaceX Crew-2 docked to the ISS after a 24-hour journey; SpaceX Crew-3 arrived at the ISS after 21 hours; SpaceX Crew 4 achieved it at just 16 hours; while it Spacex Crew 5 (preceding AlNeyadi) reached the ISS after 29 hours.

10.23am: We're almost there

We're now down to the last few minutes before liftoff. Before that epic moment, here's a quick look at what happens next once the spacecraft blasts off.

Dragon Endeavour will accelerate its four passengers to approximately 28,000kmph, putting it on an intercept course with the space station. The crew will dock at approximately 2.38am EST (11.38am) UAE time on Tuesday, February 28.

10.16am: Two sets of spacesuits

AlNeyadi and his Crew-6 colleagues have two sets of spacesuits. The one they are wearing now is worn inside the Crew Dragon spacecraft during launch and ascent to space. It will be the same suit they will use on the way home during re-entry into Earth's atmosphere.

The other set is designed for spacewalks or Extra-Vehicular Activity (EVA), and this type of suit is called by Nasa as EVA suit, which is actually a miniature spaceship shaped to conform to human body that protects astronauts from radiation, dust, debris and extreme temperature while in space or on the Moon.

This is how the UAE flag is stitched on AlNeyadi's suit:

Temperatures on spacewalks may vary from as cold as -121 degrees Centigrade to as hot as 121 degrees in sunlight. EVA suits provide astronauts proper pressure for the body and supply them with water to drink and oxygen to breathe.

AlNeyadi is trained to do spacewalk.

10.10am: Falcon 9 at the moment

The launch escape system for the Dragon spacecraft Endeavour is now armed. From liftoff until they reach orbit – roughly 12 minutes – the crew would be able to escape safely in the unlikely event of an emergency, Nasa said. RP-1 (rocket grade kerosene) loading and first stage liquid oxygen loading has begun.

---

10.07am: Helmets closed

The crew access arm has retracted and the astronauts have closed their visors. The Dragon launch escape system will now be armed in the unlikely event of a contingency. After, SpaceX will begin loading propellant into the Falcon 9 rocket for launch.

9.50am: 'It's a go for launch'

Commander Stephen Bowen has confirmed that SpaceX’s Dragon Endeavour spacecraft is ‘Go’ for launch. Weather remains favourable, and the team is on target for a 10.45am (UAE time) launch.

SpaceX tweeted a clip of the astronauts waving Earth goodbye:

In less than an hour, the SpaceX Falcon 9 rocket, with Endeavour atop, will lift off from Kennedy Space Centre’s Launch Complex 39A in Florida.

The crew will dock Endeavour to the forward port on the space station’s Harmony module about 25 hours after liftoff.

9.43am: 'Until we meet again'

An hour before liftoff, AlNeyadi tweets a heartfelt 'goodbye' message for the UAE and everyone he's leaving behind on Earth — for six months.

Here's his tweet:

9.35am: Ground crew in action

All eyes are on their monitors at ground control room of the MBRSC, with the crew following the mission closely.

Here's what's happening behind the scenes:

Outside the control room, top officials of the centre are speaking with the media, sharing more details about the mission and the latest developments in the sector.

9.30am: Sky still looking great

Weather officials continue to predict a 95 per cent chance of favourable weather conditions for SpaceX Crew-6 launch from Kennedy Space Centre.

The flight crew is seated and secured inside their Dragon Endeavour spacecraft preparing for their 25-hour journey to the International Space Station. About 45 minutes prior to liftoff, the SpaceX launch director will conduct a poll of mission managers to determine if they are ready for launch.

"With a successful ‘Go for launch’ decision, the crew access arm will retract, the crew will close their visors, the launch escape system will be activated in the unlikely event of a contingency, and SpaceX will begin loading propellant into the Falcon 9 rocket for launch," Nasa said.

9.21am: Astronauts' training

With a little over an hour before the launch, the energy is picking up in Florida. Experts on the ground share their insights on what these space missions mean for countries and for the world.

Salem Al Marri, director-general of the MBRSC, took the opportunity to explain the UAE's mission of honing its own space crew — which started in 2017. In 2018, the country announced its first astronauts: Hazzaa AlMansoori and Sultan AlNeyadi.

“It’s a big responsibility for us. We kicked off this astronaut programme in 2017. We wanted to have a sustainable programme, a programme that has a positive impact on human space flight. So we selected our astronauts. We made sure they are training with Nasa, with Roscosmos. They get the full set of training to become astronauts that can contribute to the advancement of space flight. So, this mission is a fulfillment of that vision today," Al Marri said.

9.10am: An international mission

For Nasa, international partnerships are the 'lifeblood' of its commercial crew programme. Nasa administrator Bill Nelson said: "As we go back to the Moon, it’s (no longer) just the US government, it’s now an international mission. It’s a public-private partnership as we go back to the Moon and then to Mars. In this particular case… the crew going to the International Space Station (ISS) it’s very much a both of those as well.”

Remember when AlNeyadi shared how a large UAE flag is now on display at a Nasa training facility? All these flags at Nasa do symbolise the global nature of space endeavours.
